Chapter 1

“Shining, are you sure you’ll be okay without me?” Cadance kissed her husband gently on the cheek, searching his eyes.

“Honey, you know I can take care of myself. Just take some time off and relax with your parents. I’ve got plenty of frozen hayburgers, and by now our advisors practically run the kingdom without our input.” He nuzzled her gently, inhaling deeply of her almost rose-like natural scent.

Princess Cadance had been smelling even better with every day her pregnancy progressed, and even though she wasn’t due for another six months, she was just beginning to show the hint of a belly bulge. Shining Armor sucked tenderly on the hot, throbbing vein of her neck, smiling as she groaned and pushed him away.

The princess looked her muscular husband up and down, smiling knowingly. “As much as I enjoy your little love bites, Shiny, please don’t give me any strange marks before I go home to mom and dad,” she whispered into his twitching white ear.

“How can I resist, when my wife has such a smoking hot body?” he replied, reaching out with his teeth to playfully nip at the air next to her cheek.

Her tail flicked back and forth in response, and she leaned her neck against his neck before dragging her body close to his body. They ended their farewell by gently touching their horns together, a little zap of electric magic making them both gasp with pleasure.

“I’ll be back in just two weeks, love. I’m sure you can keep yourself company that long.”

He put on an affectation of hurt and loneliness, pushing out his lower lip. “B-but…?” His eyes darted backwards to his own underbelly momentarily.

“Okay, but this is just for the spank-bank, hubby. The train’s about to leave without me!” The pink alicorn turned around slowly, wiggling her flank at her husband. Her tail flicked back and forth to give him the most teasing of glimpses at her vulva, but his eyes stayed mostly trained on her luscious rump.

He didn’t want to hurt her feelings so he didn’t say anything, but the addition of baby-weight seemed to make her asscheeks so obviously larger, more kissable, and beautifully round. Shining Armor mentally gathered a series of snapshots to keep himself occupied later.

“Love you, Shiny,” she cooed as she finally boarded the train. Her personal assistants had already loaded her luggage, and she blew her husband a kiss through the window.

“Love you too, Cade,” he mouthed back at her, smiling and willing his body to keep itself under control and sheathed in public.

Twilight Sparkle yawned and rolled over, letting her wing filter the sharp winter sunlight that streamed in through the tall crystal windows of her castle.

Sure, she was the ‘Princess of Friendship’ and yeah, there were plenty of ponies who loved to idolize her. But in her humble opinion, she wasn’t much of a leader, at least compared to the way her five best marefriends (and Spike!) kept her aloft. So missing the beginning of the day wasn’t too much of a problem for her, especially on a Thursday. Who does anything important on a Thursday, anyway?

Scrabbling little claws could be heard down the hall, though. Rather than wait for Spike to pound on the opaque crystal, she tossed her bedsheets to the floor and opened the double doors just moments before he arrived.

“Twilight!” he cheerfully exclaimed, “you’re awake!”

Pressing one hoof against her forehead, she groaned a positive reply. “I’ve asked you not to bother me this early, haven’t I?”

“But it’s almost eleven?” he tried to counter.

“Oh. I guess I stayed up reading a lot later than I thought last night. Well, I’m up now, anyway,” she relented, grinning at the little dragon. No doubt he was hungry and tired of eating pathetic dried snacks from the pantry.

Almost on cue, he scraped one toe-claw on the floor absentmindedly before asking. “Do you… want to make some breakfast?”

With a swift grasp of her magic, the Princess scooped her sidekick up and placed him on her back. She gave him a quick snuggle with her bedhead mane before trotting down the hallway. “Of course. What do you think about crepes today?”

“Sounds great!” The little dragon grinned and hugged his friend’s neck tightly as he rode her comfortable back towards the kitchen.

Meanwhile, in another corner of Ponyville, a green earth stallion straightened his mane while looking in the mirror. Pinewood’s small yet ever-growing little empire of construction certainly occupied most of his daily efforts, not to mention the oft-sleepless nights he suffered. Half the time he couldn’t shut off the thoughts of paperwork, planning, and pay schedules. Other nights, like the last one, he found his mind wandering aimlessly back to the mare--

No. He shook his head again, trying to direct his thoughts back to productivity. She’d made her intent clear to him in words, though at times her actions had taken them down much more intriguing roads of lust and passion.

Twilight Sparkle had certainly been a most entertaining lover, and in the dark of the night they’d reached impassable heights of passion together, but-- Once their more carnal needs were fulfilled, they did have some public duties to attend to, separately. He recalled the mutual agreement, just weeks ago, with a hint of longing:

She’d already proclaimed her devotion to him publicly, showing off to the crowd how powerfully his masculine physique fit like the missing puzzle piece to her lithe velvet body. After bringing each other to orgasm repeatedly and continuously, the purple princess had been covered, both inside and out, with sticky white strands of his ownership.

“I love you, Pinewood,” she had whimpered, as the observing ponies devolved into a public orgy of give and take, push and pull.

Her green stallion had helped her away from the crowd, and once alone they’d shared a long silence that seemed to convey far more than any words ever could.

I think… I think we both might need a little rest now, don’t you? the princess had intoned directly into her lover’s thoughts with a telepathic link. Come sleep with me?

And soon enough the two had arrived back at her bedroom to slumber, a warm and intimate bundle of two loving ponies.

The following morning, they had known it was time to return to the daily grind. After just a quick romp, they had showered playfully together, each cleansing the other’s body with tender hooves and effervescent kisses underneath the warm water. Once prepared to meet the day professionally, he’d left her behind at the castle.

“I’ll be back before you know it, love,” he’d murmured into her ear, letting his lips just barely caress the ticklish lavender softness.

“Don’t keep me waiting,” she’d replied, rubbing her bone-hard yet still warm and velveteen horn against his cheek.

That had been weeks ago! Weeks! A stallion as virile as Pinewood was finding it so hard to concentrate with this much pent-up passion bubbling underneath his skin!

He splashed cold water on his face for the eighteenth time before heading out the door. Self-stimulation wasn’t relieving the root pressure, either, but Pinewood had been far too busy with his responsibilities to actually take any time off work to meet with Twilight.

Curse this booming economy! he rolled his eyes and headed off to the nearest construction site, hoping there would be no hang-ups or delays in the production schedule. Ponyville had come to rely on his team of skilled workers to deliver on time, but they were simply demanding too much out of the limited labor pool he had access to.

Spike was just slurping up the mess of spinel syrup on his chubby cheeks when he and Twilight heard a friendly knock at the front door of the castle.

“That’s odd,” the princess mused while dabbing a moistened napkin on her baby dragon’s cheek. “Rainbow Dash and the others don’t usually knock.”

Keeping her excitement bottled up, she trotted over to the door. Secretly she hoped it would be Pinewood after all this time, though she knew it was unlikely he’d be free in the middle of the week like this.

Letting the mass of the counterweight do most of the work, she tugged on the opening mechanism with a little ball lightning of her magical powers. Smiling, she greeted the outdoors and warmly called out with a little bit of silly ceremony for fun:

“Princess of Friendship, how may I help you?”

“Twily!” exclaimed a familiar voice, and Shining Armor almost tackled his sister to the iridescent floor in his big loving hug.

“Shiny?” she asked, a little confused at seeing him here unannounced, but happy to see him nonetheless.

“Cadance is off to visit her family, and I thought it would be a perfect time to come see my little sister! How have you been, you little booger?” He kissed her on the cheek before rubbing his hoof against her mane in a feigned noogie.

“Bluh! Stop it, tangle-fuzz!” she protested, squirming her own legs into the sensitive pits between his barrel chest and his forelegs, trying to tickle him and gain the upper hoof.

“Hey!” he yelped, tumbling head-over-hooves with her as they wrestled for sibling dominance.

Spike walked in from the dining room just before things got awkward, offering Shining Armor a clawful of half-eaten breakfast pastry, coated with tooth-wrecking turquoise.

“No thanks, little buddy, I already ate.” Shining and Twilight giggled together, and she shut the door behind him after he pulled his overnight bag inside the castle.

“I’m so glad you decided to visit,” she squealed. “Things have been a bit too quiet in the last couple weeks, and I could use some company.”

“Hey! I’m not boring, am I?” asked the little green-eared dragon.

“I’m sure she doesn’t mean it like that, Spike,” the white unicorn reassured him, smiling. “Twilight and I just have a lot of gossip to catch up on, and it’s always better to keep these kinds of discussions face to face, that’s all.”

“Gossip?!” Spike exclaimed, his eyes darting back and forth. “Like what you and Cadance are planning to name the foal? I personally nominate Spike Junior, because of how awesome a team we’ll probably make.”

“We’ll take reasonable suggestions into consideration, of course,” Shining replied diplomatically, though he was trying not to roll his eyes with Twilight. “Why don’t you show me around, Mr. Awesome?”

Pinewood wiped a thin film of dirty sweat from his brow. Though it was still winter and the temperature outside was just a few degrees above freezing, it was warm to the point of being stuffy inside the current worksite. His team was putting the final interior finish on this particular apartment building, and after today’s efforts cutting and installing the trim for all the doors and windows, it would definitely be ready for the painters tomorrow morning.

Thank goodness, too. He could already feel the weight on his mind start to untangle, as if he’d actually be able to sleep tonight. He felt a pang of loneliness and decided that he’d earned a little break after this checkpoint, and after making sure none of his workers had questions about their responsibilities, headed home to wash himself up. It was just after noon, and the cool air quickly prompted him to bundle his scarf tightly around his neck as he trotted down the streets of Ponyville.

After a relaxing shower to remove any traces of sawdust or caulk from his fur (taking special care to clean underneath his hooves as well) Pinewood truly felt refreshed. He looked at himself in the mirror, feeling a completely different set of emotions than when he’d done it just a few hours earlier. He felt accomplished, satisfied, and most of all energized. The untamed physical energy of his body was now finely tuned like a white-hot acetylene flame, ready to focus its desires on his mare. He knew that there would be no denying himself now-- he had the time and energy to visit Twilight and reignite the passions they’d previously had to shelve for far too long.

Pinewood took a few more minutes getting himself ready, brushing his own forest green fur until it was nearly glossy. He smiled at himself, noticing how full his sheath felt underneath him. His stallionhood wasn’t obscenely erect, just pleasantly heavy; it was like a half-chubby sausage that hung nicely in front of his two larger-than-average gonads. He grinned and moved his tail back down to cover most of his package, then walked through a quick spritz of earthy cologne before heading out towards Twilight’s castle.

He already felt a change in the way others looked at him, now that he moved with a subtext of physical desire. Mares glanced surreptitiously up and down, half wanting him to see how their eyes wandered across his muscular physique. Stallions could tell that he was focused with the drive of testosterone, the drive to breed and take control of what belonged to him. He loved every bit of the public attention, feeling a little twitch of pride in his pelvic muscles with every step. He was going to meet his lover.

Arriving at the most luxurious architecture in town, Pinewood knocked three times on the vast crystalline door. Simultaneously he reached out with his mind, trying to find the purple tendril of Twilight’s consciousness somewhere out there in the dark.

Pinewood, is that you? he heard the telepathic voice of the Princess of Friendship. She sounded surprised at first, then a bubbling of various other emotions suddenly came washing through the green stallion. She must have realized the subconscious throbbing force of his desire which came across on the bi-directional link between them.

He replied to her wordlessly, smiling at his own reflection in the faceted doorknob. Good afternoon, my love. I’m sorry I kept you waiting so long, but I’m here now. Forgive me?

Of course, Pine. But I have to apologize too-- my big brother is visiting from out of town. I’m sure we’ll be able to make some private time, though. Twilight opened the door and embraced him. She seemed to be holding back at first, but after a moment of silently inhaling each others’ scent, the hug became more passionate.

“Oh, Twilight,” he whispered in her ear while his hoof traced its way down her back to rub tenderly into the base of her wings. “I’ve missed you so much.”

“Me too,” the purple alicorn replied with a small moan. His body was already having its effect on hers, and she knew that it would only be a matter of minutes before her marehood would begin to betray her lust. “Come say hi to Shining Armor. Have you two met before?”

“Captain of the Canterlot Royal Guard? Prince of the Crystal Empire? I’ve heard of him, of course, but I’ve never had a chance to meet him in the flesh. I hope he won’t be overprotective of his little sister.”

She kissed Pine on the cheek briefly, knowing she wouldn’t be able to stop herself if she spent any time near her stallion’s lips. “I bet you two will get along great.” Her horn, hot with the rush of blood to her face, touched his ear and made him shudder impatiently. It would definitely be a challenge to keep themselves restrained until they were alone.

She caught him up on the minor details of her brother’s visit while they walked down the hall to the living room, her soft flank rubbing against the rippling muscle of his thigh as they walked in perfect step with each other.

“Shiny, I’d like you to meet my coltfriend, Pinewood,” she announced as they entered the room. “Pine, this is Shining Armor.”

“How do you do?” the green stallion gave a friendly smile.

“Coltfriend!” exclaimed Shining. “Nice to meet you, Pinewood. I was starting to think my sister would never find somepony who’d put up with her silliness. Tell me, is it blackmail? What kind of dirt does she have on you to force you to stay?”

Twilight gave her brother a friendly shove with one hoof, but it didn’t really make him budge.

“Dirt? Oh no. Twi and I found ourselves to be an unlikely match, but there’s just some kind of connection between us that I can’t really explain.” Pinewood gave Twilight a little nudge with his muzzle, just barely kissing her shoulder. “She’s much more than just a marefriend to me.”

A knowing grin flashed quickly across Shining Armor’s face, as he realized the two lovers had been intimate-- probably more than once, and definitely to a state of mind that was much deeper than vanilla sex. He found himself suddenly blushing at the ideas that were beginning to float up inside his head. The white unicorn now understood that all this tension in the air wasn’t simply his own loneliness for his wife, but also a charged electric field between this tall green stallion and his beautiful purple sister.

At the very same moment, Pinewood sensed something radiating from Shining. Almost the same kind of attractive glow that Twilight seemed to cast inside his mind, like a mesmerising candle in the blackness. He smirked and ran his hoof down Twilight’s neck, slowly following the hidden veins and muscles that led toward her heart. He was pleased when he saw Shining’s eyes follow his green hoof down the slender bosom of the Princess. Pine hadn’t planned on showing off like this, not for her brother… but if Shining was going to watch, he couldn’t resist putting on a show now.

Spike, having previously stuffed himself silly with whipped cream and carbohydrates, was already half-asleep on his comfy chair. The dragon rolled over to face his pillow and began to snore steadily.

Twilight felt the awkward pause between the three ponies seem to grow exponentially.

“So, Shining Armor…” Pinewood remarked, “you’ve been away from your wife for how long?” His hoof ran back up Twilight’s shoulder toward her wings, which were now extending steadily past half-mast.

The unicorn was almost breathless, watching his sister display such submission to Pinewood’s gentle touch. “S-six days now…” he whispered back, suddenly realizing how the green earth pony seemed to be drilling a hole into him with his gaze. He licked his lips unconsciously, then felt a sudden shift in his own weight as blood rushed to fill his sheath.

Twilight’s eyes were closed now, and she seemed to be arching her neck, aiming her muzzle skyward and leaning into Pine’s hoof which followed its way down that sensitive line of her backbone, making her twitch and stretch like a cat. She finally stopped her gradual rotation, ending with her tail pointed straight up before Pinewood.

The green stallion’s hoof rested between her tail and her cutie mark, just inches from her blushing marehood and the tight donut that crowned those puffy lips like a warm and welcoming jewel.

“I used to… dream about getting a chance to see my sister like this…” Shining gulped, not sure why Pine was teasing him this way. And why was Twilight acting so calm, presenting like this in front of her brother as if to flaunt her feminine power and make him jealous of Pine? An odd thought seemed to twinkle through Shining Armor’s mind now, wondering how it might have felt for her to take Pinewood’s member. He blinked and realized he’d been staring at the green stallion’s belly for some time now, entranced as he watched Pinewood grow in throbs and pulses until fully erect.

The earth pony was certainly blessed in the masculine department. The dark green shaft was perhaps an inch or two longer than Shiny’s own midnight blue tool. And what a head on it too! Pinewood was clearly king of his own body’s responses, and the throbbing flared ridge of his cockhead was already glistening, near orgasm but held back like a powerful dam.

“It seems my magical masculine power is working double time for me today,” Pinewood began explaining, “and you’ve been caught in the crossfire of our attraction. Twilight, kiss your brother.”

Two sharp gasps. The princess looked at Pine for half a moment, then met Shining’s eyes. “Pine?!” she hissed. “What about Spike?”

“Then I guess you’ll have to be quiet about it. I don’t ask twice, you remember.”

Twilight took two steps closer to Shining Armor, her face blushing as she considered the opportunity to finally taste her big brother’s lips.

The white stallion seemed stunned, unsure of whether this was a dream or real life, and felt himself pucker up in anticipation. “Oh, Twily…”

The siblings met muzzle to muzzle, first hesitantly then quickly letting go. Lips played out over lips, nostrils flared wildly, and two tongues grazed across each others’ wet surfaces electrically. Shining’s vision flashed with a thousand colors as he savored this moment, not caring how wrong it felt in the back of his mind. That part seemed so easy to keep quiet right now, with the great lecherous throbbing of heat in his stallionhood keeping him so excited.

Pinewood grinned, knowing the unicorn would soon find it impossible to turn back. “Why don’t we go to the bedroom, Shining Armor? I think we have something to discuss.”

“Uhm,” he replied, panting for breath and restraining his lips from latching back onto Twilight’s. “Okay.”

Pine led the way, followed by Twilight with her wings held high. Shining trotted quickly to catch up, his mind reeling from both the recent events and the intoxicating cocktail of scents that he inhaled from both ponies ahead of him.

Locking the bedroom door behind them, Pinewood turned and faced Shining. “So as you can probably see, Twilight’s not only my marefriend. She’s agreed to be my submissive toy in the bedroom, and that includes following my directions when I ask her to be used by anypony I desire. The fact that you’re her brother is only a bonus for me, and I feel like the two of you are starting to agree with me. Twilight, suck my cock. Put on a show for your brother, too.”

The princess felt giddy as she tucked her wings back down halfway and then knelt on all four knees under Pinewood’s standing body. She was careful with her horn, laying it gently against her stallion’s belly while she turned her head to rest her lips halfway up his green shaft. Her rump was forced to angle upwards at Shining’s face, and she flipped her tail up so the silken purple and magenta fibers made a beautiful fan across her lower back.

Shining groaned at the sight. His little sister’s round anal muscle winked twice at him, and then suddenly her outer lips blossomed open to reveal the rich pink flesh of her marehood. He was suddenly hit with a concentrated scent of heat and desire, and felt his tongue involuntarily extend out past his lips for a moment. He’d only ever been with Cadance before, and Twilight’s body was so new and unexplored, though so incestuously familiar on the outside. “But… I’m… married,” he tried to protest.

Pinewood let out a slow moan as he felt his mare’s lips glide passionately up his length to suckle his head. He’d need to coerce his rod to soften slightly for her before she could fit it in her muzzle, though. “What your wife can’t provide to you, can’t hurt her. Go ahead and taste your sister.”

Twilight looked up from her position underneath Pine, and felt the thickness of the flared head begin to subside just a tiny bit. Staring her brother right in the eye, she slurped Pine’s cockhead into her mouth, coating her lips and tongue with the slick clear fluid that immediately oozed out from it.

“But I--”

It’s OK, Shining. Suddenly Twilight’s voice filled both stallions’ minds. I want this too.

One more second of hesitation from the royal guard. His heartbeat seemed to be pounding impossibly loud in his ears, and he thought he was hallucinating his sister’s approval.

Suddenly Twilight took away his choice, grabbing his mane with a strand of magic and moving her flank backwards at the same time. Her marehood collided with his muzzle, and both siblings moaned loudly.

Oh god, Twily, you taste so good! echoed through the three-way link now. He pushed himself forward, not needing any encouragement. He was hungry, starving for her juices, running his tongue up and down each fold slowly, carefully, rounding the corner near her ponut and then coming back downward on the other side. He stopped short of her clit, opening his eyes to see the effect he was having on his sister’s body. Then with a shove he encircled the sensitive button, forcing Twilight’s body forward and her mouth deeper onto Pinewood’s cock.

Pinewood bit his lip and let Twilight take half his length now, her throat muscles just beginning to tease and swallow at the encroaching ridge of his cockhead. With a quick exhale, he thrust forward, breaching that tightness with several more inches of his member. Twilight’s wings popped up and rubbed against his body, as she was forced to begin holding her breath. Once Pinewood had entered the deepest parts of her muzzle, he wouldn’t pull free until he was finished with her. Precum was now dribbling like a leaky faucet directly into the alicorn’s belly, and the look on her eyes clearly showed that she was loving every second of this.

Instincts were the only thing running through Shining’s mind now; instincts and love. He tried to turn Twilight’s body, pushing her into a position where he’d be able to mount her without interfering with Pinewood’s pleasure. But the green stallion deftly shoved him aside.

“I get her first.” Pine commanded, motioning with his head toward the bed. “Lie on your back, Shining.”

A little confused, the white unicorn walked over and laid down on the bed, his legs splayed towards the ceiling and his head upside-down looking at Twilight.

“Get on top of him,” Pine said to Twilight. She followed, settling into position with her muzzle just inches from her brother’s cock. She rested her clit directly on his waiting lips, shuddering with anticipation.

Pinewood hopped up to mount her now, his thick green tool completely covered with precum and saliva now. It slapped Shining on the cheek, and the prince suddenly realized he was powerless to move away from the impending onslaught.

“I like lots of tongue, don’t you?” Pine suggested, pushing his cock forward so it slid between Shining’s muzzle and Twilight’s blushing marehood.

Twilight nearly squealed with delight, but instead she quickly opened her mouth to engulf Shining’s cock. She only took it halfway at first, slowly pulling her head backwards so that she could mix the mess of fluids across its surface. Her tongue swirled around and back again as she suckled harder and harder, taking another half inch of blue tool into her throat with every bob.

Pinewood pulled back, letting his cockhead rest on Shining’s lips. “I don’t feel any tongue. Is something wrong?”

“But I--” In a flash Pine’s cockhead entered the unicorn’s mouth, grinding wetly against his tongue.

“That’s better,” the green stallion sighed, pumping back and forth a couple times to get his point across. He pulled back out and then dipped his cockhead into Twilight’s waiting pussy, groaning as he felt it spasm and tighten rhythmically. He stopped with he was only halfway in, then pulled back out to switch to Shining’s mouth again. “More tongue, I said.” This time Pine’s cock knocked on Shining’s throat, making the unicorn gag and squirm. “Don’t worry, I won’t suffocate you,” Pine reassured him between little gasps.

Shining’s body clenched down around Twilight’s, his legs grabbing hold of her frame for support. This allowed him to thrust his hips upward, suddenly hilting himself inside his sister’s throat. He felt a burst of involuntary magic at that pleasurable sensation, and at the same time his own throat opened up to allow Pinewood full access. The pain was indescribable, and he felt a gag of precum fill his sinuses. But the pleasure! The pleasure was immensely more convincing, and though his throat muscles burned with pain, he found himself wishing to be nowhere else but here and now. He mimicked Twilight’s swallowing motions that were driving him mad with ecstasy, and was pleased to feel Pinewood’s member throb and leak another squirt of fluid in response.

“Good boy.” Pinewood pulled back now, switching to Twilight’s marehood again. Now that his appetite was whetted, he gave her several steady thrusts, plunging completely into her to the hilt and then drawing himself out entirely before repeating the motion. Every time his cockhead slipped free from her tender lips, he felt a fresh glob of precum squeeze out onto Shining’s waiting tongue. The unicorn was eagerly lapping at the underside of Pine’s cock with every pass, and even kissed his dark green balls between flicks of Twilight’s clitoris.

After at least a dozen of these long pistoning motions, he returned to Shining’s maw. “Oh, fuck yes.” He didn’t hold back this time, grinding his thick cockhead against the tight muscles of Shining’s throat over and over, in and out until he knew the unicorn would be at the limits of his saved breath.

Shining’s forehoof tapped against Pinewood’s flank in the universal request for mercy.

“What a weakling,” Pine scoffed and released himself from the spasming depths of Shining’s muzzle. Twilight’s inner lips were even wetter and more fiery this time he plunged into them, and he felt the little secret folds of her flesh alternate between yielding and fighting his advance, pulsing hotly between suction and pressure. His mare was nearing her orgasm, and he knew that he wouldn’t be able to resist skydiving off that mountaintop with her.

Shining Armor sputtered for air, stopping his oral attention for just a moment. Then he was hit with a cascade of liquid that splashed out of Twilight’s pussy each time Pinewood hilted into her. It tasted like little more than hot slippery water, but it was loaded with the irresistible scent of his sister. He found himself drinking down every little bit that he could catch, burying his muzzle between Pine’s tight and churning ballsack and Twilight’s white-hot love button.

Twilight’s wings were flapping up and down rhythmically now, causing her throat to slide back and forth along her big brother’s cock, coaxing him to join them in their ecstasy. She bucked back harder onto Pinewood’s shaft, grinding her rump into his crotch and then filling Shining’s mouth with her winking clit. It had grown to nearly twice its initial size now, and was so sensitive that her thighs began to tremble around Shining’s head.

Piiinne… the princess whimpered in her stallion’s head. I need you to cum…

His cockhead, flaring suddenly inside her warmth and rubbing up against the swollen and sensitive entrance to her womb, obliged. The first pulse of seed was propelled from deep within Pinewood’s body, pressurizing the spongy underside of his member and making Shining armor moan as he realized what was happening right against his face.

Pinewood grunted and pounded harder into Twilight, forcing her head down until she was as deep as possible onto Shining’s cock. The unicorn came simultaneously, calling out his sister’s name as he filled her belly with several thick ropes of cum.

“Twily!”

Over and over the three ponies fluttered in the throes of pleasure, their muscles all seeming to be connected in one sweaty beast of sensuality. Twilight dutifully swallowed every bit of her brother’s offering, until she felt him begin to soften slightly in her throat. But Pinewood had only just begun, and she felt the familiar cramping of her inner muscles as there were already more than twenty throbbing jets of the green stallion’s wonderful seed now filling her womb.

“Stay on his cock, Twilight,” Pine instructed, pulling his still-diamond-hard member out. Most of the cum already inside her body would stay where he’d placed it, but the subsequent spurts began to cascade out her puffy labia, directly onto Shining Armor’s muzzle. Twilight shuddered with the sudden emptiness when Pinewood switched back to thrusting into her brother’s lips, though she was able to keep her muscles tight enough to retain the gallon of cum.

Shining was exhausted and in no shape to resist Pinewood, so he reveled in the coating of cum on his face, then lazily swallowed the still-squirting cockhead that was offered to him. His head was still spinning with the endorphin rush of his orgasm, and the taste of Pinewood’s creamy load seemed to have some kind of amplifying effect. He felt his cock immediately re-stiffen inside Twilight’s mouth, and he swirled his tongue around and around Pine’s green member before it plunged deep into his throat again.

Sighing with pleasure, Pinewood unleashed an even heavier flood of seed into Shining Armor now that there would be no way for him to spill any. He grinned when he felt the unicorn tremble with another orgasm, throat muscles tightening and releasing, tightening and releasing around the unstopping flow of thick salty lifeforce.

Again Twilight swallowed Shining’s cum, though this second one so soon after the first was thinner, more like watery marecum than true stallion seed.

“Harder, Twilight. Make him cum over and over with my cock in his throat. Make sure he associates the pleasure with my taste.”

She renewed her actions, milking Shining’s cock mercilessly though he squirmed and shook with hypersensitivity that bordered on torturous pain. She involved her hooves as well , rubbing and squeezing her brother’s balls which she knew must already ache with emptiness.

Pinewood felt Shining’s body buck hard, and he pulled back out while simultaneously reducing his river of cum to a mere trickle.

“Stop!” the unicorn begged, coughing up a mouthful of sweet and sticky goo.

“If you really wanted me to stop, you’d use your magic to stop me.” Pinewood plunged forward again, then pulled out to let the unicorn breathe.

“But it’s too much to swallow!” Shining sputtered, shaking his head left and right. But it was true, he wasn’t exactly resisting.

“You’ll be alright, I promise.” Pinewood thrusted deep into the now-submissive pony, releasing another torrent of cum.

It filled Shining’s stomach until it was painful, then the unicorn felt a cramping muscle give way to allow the flood to travel deeper into his body. He was unable to relax, though, as another orgasm throbbed hard in his sore stallionhood.

Why won’t-- it-- go down?! he wondered, grunting around Pine’s throat-filling firehose as he trembled another watery cum into Twilight’s mouth.

Because you love my cock now, Shining. As long as I keep feeding you my cum, you’ll always find my cock irresistible, and those sissy little squirts of yours are a fun little side effect for you. Pinewood smiled at Shining, pulling back out to paint the unicorn’s face and mane with another hot string of cum before thrusting it inside that wonderful throat again.

Twilight also was about to cum again, sandwiched between the two stallions like this, and when she felt a fourth? or was it a fifth? rising squirt of sweet nectar burst forth from her brother’s cock, she moaned and shuddered a waterfall of marecum onto Shining’s face. Her wings flexed backward to caress Pine’s body as she came down from this orgasm, feeling blissful and relaxed now that she’d fulfilled her stallion’s wishes.

Finally satisfied with Shining’s eager motions on his cock, Pinewood willed his member to reduce in size and flow. A few more dribbles of his delicious seed got on Shining’s face, and Pinewood hefted his body off the 69-ing siblings. The green stallion turned around to lie on his back in the center of the bed, beckoning both of his conquests to to lie with him.

Weakly, Twilight Sparkle lifted herself off her brother and cuddled against Pine’s left shoulder. Her muzzle was surprisingly clean, for she had expertly swallowed Shining’s cum without spilling any. Her marehood, however, was a different matter, and she felt the sticky coolness of drying seed which coated her underside and thighs. She kissed her stallion on the cheek, and sighed, already drifting off to a restful sleep.

Shining Armor followed, awkwardly mimicking his sister on Pinewood’s right side. He chuckled and wiped most of the cum off his face with a hoof before nuzzling Pine’s muscular chest and falling asleep as well.

Chapter 2

When Shining Armor finally awoke, it was dark. Perhaps two in the morning, with just the calming light of a crescent moon illuminating the crystalline bedroom. As his blurry eyes adjusted to the darkness, he only gradually realized that he was cuddling with a stallion.

And his sister.

He was cuddling with a stallion and his sister.

And he had the stallion’s cum all over his face and in his belly.

And his own cum was on Twilight Sparkle’s face. And in her belly.

His eyes widened as he realized his cock was quickly hardening again.

“Good morning, Shining,” whispered Pinewood, rubbing gently down the unicorn’s shoulder with one hoof.

Shining Armor shivered slightly. It was partly from his remaining surprise at what he’d done last night, and partly from how good it felt to let the green stallion caress him like this. He’d always been straight as an arrow, always lusted over beautiful mares alone, and never considered intimacy with one of his same sex.

But here he was. Shining’s legs were intertwined with Pinewood’s. And the back of Shining’s neck nestled in the warm pit of Pinewood’s foreleg. Shining’s horn rested gently across Pinewood’s upper chest, the soft green fur like a grassy field for Shining’s gracefully tapered spiral bone.

And Twilight… oh, beautiful Twilight slumbered in the mirrored position, her face just close enough to his that he could just lean slightly to kiss her…

What was wrong with him?! He saw a little snail-trail in the corner of her mouth, no doubt a remnant of his own sticky cum.

The white unicorn suddenly gasped as he felt Pinewood’s thick green member throb impatiently between their thighs. He now realized that their cocks were crossed with each others’, and if they humped their hips forward they could fuck each others’ firm yet yielding abdominal areas.

Pinewood did just that, grinding his body slowly so his cock would probe and glide across the supple skin of Shining’s crotch.

“Goo--hood morning, Pinewood!” Shining Armor gasped his response, bucking his own hips so he could feel more of their two cocks. His thick dark tool twisted and shoved around Pine’s, each one gradually rising to its full hardness against the other.

A pang of guilt or shame suddenly made Shining Armor stop moving. “Wait, I don’t think we should do more…” he tried to protest.

Pinewood stopped as well when he heard that. “Why do you say that? Aren’t you enjoying yourself?”

Shining Armor bit his lip and tried to clear his head. Trying not to wake Twilight, he turned his head upward so he was nearly kissing Pinewood instead and whispered, “I mean, I’m a married stallion! I can’t do this to Cadance! And me being with Twilight is just wrong too!”

“But you don’t regret last night, do you?” Another beseeching throb of Pinewood’s cock against Shining Armor.

The unicorn gulped involuntarily. Why did he salivate like that just now? His tongue felt all slippery and ticklish inside his mouth. “No, last night was amazing… I just don’t know if it’s a good idea.”

“I’m sure Cadance will understand. She is the Princess of Love after all, and if her stallion has needs she can’t fulfill…” Pinewood’s cock throbbed again to drive home the point.

Shining still seemed unconvinced. “And what about Twilight? I mean, she’s my sister… fantasies when I was young might have been okay, but actually doing anything…” He looked back down at Twilight’s peaceful face.

She really was beautiful, especially now. Twilight Sparkle had a bit of an afterglow about her, with maybe the faintest of pulsing magical energy that was just barely present surrounding her horn. If you were close enough to feel it, that is.

Shining felt his sister’s powerful magic in his lips and in his own horn. It reverberated with the different, yet complementary beating of Pinewood’s heart so close to the unicorn’s ears.

“I was absolutely serious earlier,” Pinewood murmured soothingly. “Twilight and I have a bond much stronger than most ponies in love. She gives herself unconditionally and unstoppingly to me. So you can trust me when I say she loves you enough to want your happiness in everything, including the deepest, fiercest, and most satisfying of fantasies. I can tell that you still want to feel her marehood give way to your virile advance. You want to fuck your sister, don’t you?”

“Uhh…” Now it was Shining’s turn to throb a quick bead of precum between their bellies.

“Who says it’s wrong, if you both enjoy it, anyway? She clearly wants you too, and it would only make you both so happy.” Now both ponies’ cocks throbbed twice in unison, and Pinewood grinned at the way Shining Armor was blushing.

“Well I…” mumbled the unicorn as he wiggled his hips again.

“Then kiss the sleeping Princess,” Pinewood encouraged.

Oh, Twily, he thought as he leaned in and met his sister’s muzzle again, this time tasting the cocktail of his and Pinewood’s cum mixing between their two tongues.

Twilight’s eyes fluttered open and she sucked him harder into the kiss, passionately leaning into his muzzle and bringing her wing down to embrace his body. Her hind leg rose up to sneak in between Pinewood’s thigh and Shining’s cock, and she smiled while rubbing it for a moment.

“Good morning, big brother,” she said before yawning, turning her head away from Shining while stretching out her jaw muscles. With an adorable flip-flop of her ears, she turned upward now, giving Pinewood a kiss on on his chin. “Good morning, Sir.”

“Good morning, love,” he returned, resting his nose against hers for a second or two while hugging both siblings tightly to his furry green body. Then with a sigh he released his gentle hold, kissing Twilight four or five more times, on different corners of her muzzle. “Why don’t you present yourself for our guest? He seems to have a friendly member who would like to get to know your deepest secrets.”

Twilight gave her big brother a sultry look before untangling herself from the bed, standing up and facing the wall. Her rump was directly in Shining’s view, and even within his reach if he were to roll off of Pinewood’s body.

Before Pine unwrapped his leg from Shining Armor, though, he gave the unicorn a knowing glance. “This is a favor I’m offering to you. I only request that you consider returning it in the future,” said the green stallion.

Shining Armor gulped and considered the massive green tool that throbbed against his own. “I’ll think about it. I mean, thank you. For sharing Twilight with me, that is.”

Smiling, Pinewood gently helped Shining off the bed and then leaned back to watch the show.

Shining Armor walked slowly around his standing sister, admiring her from all angles. His cock swung heavily underneath him, and he loved how he could feel the fresh stream of precum begin to rise and flow, dripping steadily from the tip.

Twilight held her wings tightly to her body until he leaned in close to kiss the muscles at their bases, and as the twin feathered appendages slowly rose and unfurled toward the heavens, she let out a softly pleasured sigh. On the underside of her wings, the fluffy down, finer than the finest silk, beckoned for Shining to explore with his lips. The princess stifled a gasp when she felt him nibble slowly along the contours of her shoulder, tracing his way up the leading edge of her wing until his neck was extended as high as he could go. Then he reversed his motion, taking a slightly different path back down and burying his muzzle into the dreamy fluff in the crook of her wing.

It was magical, and Shining Armor savored every moment of it. He’d made love to an alicorn before, sure. But never to Twilight Sparkle. He smiled as he felt her body respond to all the same tricks he’d had to learn to please Cadance, though his sister was responding a little differently. Twilight’s body smelled so vividly unique compared to his wife’s, and Twilight’s proportions were likewise a wonderful change from what his own body had been used to touching.

Shining ran his left hoof across Twilight’s back now, gently stroking her wings to a relaxed position nestled against her sides. “I love you so much, Twily,” he sighed, kissing her neck.

“I love you too, Shiny,” she whispered back, pressing her body harder against his flank.

He wished that he could capture this moment to always have an image of Twilight like this, so eager and ready to be rutted by her big brother. It was intoxicating, this intense desire, almost dreamlike because he’d only ever thought it could happen in a dream. But it was real; it was so real that it looked real and smelled real and felt real.

And his stallionhood was really ready.

After a quick little nip of his teeth on Twilight’s neck, Shining Armor reared up, feeling his muscles all work together in that familiar masculine action of mounting a mare. He groaned loudly into his sister’s ear when his cock found its mark on the first thrust, the hot wet outer folds of Twilight’s pussy quickly engulfing the first few inches of his shaft. He froze in place, feeling a throb of precum ooze out of him in response to the overwhelming wetness. It was like his cock was already incredibly sensitive, teetering on the edge of orgasm and yet somehow still in his control.

“Oh fuck, Twilight, you feel so good,” he finally said, pulling himself backwards and grinning at how her muscles swirled and twitched with anticipation. He willed his body to have strength of muscle now, shifting his weight back and forth between his legs and Twilight’s hips as he slowly slid into her again only to stop at the halfway point.

“Nhaaa…” the princess whimpered when she realized that he was teasing her like this, holding back and then pushing forward just a tiny bit. She shivered with anticipation.

Torturously slow, Shining Armor pulled back out completely this time, letting his cockhead press downward to catch Twilight’s winking clit the next time his hips pushed forward. “Fffff…” he hissed with pleasure, grinding the upper edge of his knob against the miniature tongue-like hardness of his sister’s button. Around and around he circled that sensitive little nub with every ridge of his cockhead, fucking it harder and coating it with so much precum that a thick clear glob fell wetly to the floor below them.

“Oh, goddess…” moaned the princess. Her whole body was now writhing in sync with Shining’s, her tail pressed up against his abdominal muscles and her shoulders rising up and down trying to find the right angle. She was desperate to feel him inside her. “Fuck me, Shiny!”

One,

Two…

Three impossibly long seconds passed, each sibling holding back breath only to feel the deep pulsating throb of the other’s heartbeat and arterial thrums.

“Hnn!” Shining exclaimed as he humped forward, steadily thrusting his entire length inch by veiny inch into his sister’s welcoming depths. He didn’t stop his forward movement until he felt the inner limits of her body, that taut and powerful ending of her love tunnel, stop him and press back to resist the motion of his cock.

Squeeze!

Twilight’s tender flesh suddenly firmed up in certain delectable places, rippling tightly in a tight oval to surround Shining’s staff from its base to its hard rigid head. He bit down on her neck now, too far lost in seeking his own pleasure to care that he might be causing a little pain to his trembling little sister. She couldn’t seem to stop whimpering now as waves of dopamine and serotonin bounced back and forth along with magical and electrical impulses inside her mind and body.

“Oohh, yes…” she moaned with him. Twilight had always been so attractive, but now in the throes of ecstasy as she waited for her brother to pull back out and really start fucking her… the lavender alicorn was just too beautiful for description.

Shining Armor pulled backwards, more vigorously now, and with another sharp gasp he pounded deeply inside her again. Slap after slap, his balls swung heavily underneath his advancing cock until they collided wetly against her flank.

Twilight couldn’t decide whether to hold herself back and wait for her orgasm later, or to just let every perfect feeling take over her body now. It was almost too late for her to try to change the inevitable, anyway. Shining pulled back, hissing with intense pleasure the entire time, then pushed deep into his moaning little sister over and over and over again.

The sounds of flesh on flesh filled the air, and on one particularly hard thrust forward Shining Armor felt a deep clench of Twilight’s body resist him when he pounded firmly against the entrance to her womb. Then he moaned as he felt a new hot swirling wetness that suddenly surrounded his cock and trickled out her lips to run down his thigh… it must have been the thick load Pinewood had pumped into her womb earlier that evening!

“Fuck!” the princess yelped, wishing she could have maintained her grip on Pine’s seed. It was definitely too late to try to stop her brother from fucking the cum out of her now. She was just about the crest the point of no return, and while Shining was savoring the sensation of her creampie oozing out steadily around his hilted member, she didn’t want to waste this chance to cum hard with him. “Don’t stop, Shiny! Fuck me harder!”

Few words could ever spur a stallion into overdrive like those, and Shining Armor released his biting hold on her neck to grunt his own response. “Oh, goddess, Twily… your cunt is so fucking hot and wet…”

His cock began to throb steadily with every time he pulled backwards, and the shovel-like flare of his cockhead caught another slippery glob of cream which then fell heavily onto the floor below them. The unicorn’s mind was reeling with pleasure as he considered how wrong this all was, how wrong it should feel to gain pleasure from the sloppy wetness of his sister’s pussy, how wrong it was to let himself go and let Pinewood watch, how wrong it was to so obviously become the submissive stallion putting on a show for the earth pony’s ultimate enjoyment. But it didn’t matter, as Pinewood had said. They all wanted this, and they all were having a good time together. Wrong was so right!

The ambient glow of Twilight’s horn increased in fits and starts along with Shining’s ragged breaths as the two ponies writhed and pistoned each other back and forth. Neither one wanted the ecstasy to end, and yet with every rolling moment they were riding higher and higher up the roller-coaster ramp towards release.

“Shiny…” Twilight whimpered, feeling her knees begin to tremble. Her clit was like a glowing ember now, sending hot sparks of pleasure that manifested as little skittering sparks all the way through her body before escaping from the tip of her horn every time her brother’s scrotum slapped wetly against her crotch. Her labia were coated with the nearly frothy exudation of Pinewood’s milky white seed, and thick swirling dribbles of the sloppy mess were now covering Shining’s cock from tip to base, even running down his ballsack too.

“Oh, I…” Shining found it all too exciting that he was using another stallion’s emission to lubricate his eager cock, and as his own orgasm began to rise in pressure deep within his body, he pressed his muzzle even harder into the delightful little bit of warmth between Twilight’s ear and her neck. His nostrils flared like those of a wild mustang, and he felt every muscle in his body seem to cry out with joy as he plunged deeper and deeper and deeper into his sister’s twitching body, forcing her to feel every rock hard vein of his cock until he felt that he could slide no deeper--- “I… I love you, Twily!”

“I love you, Shiny!”

And then he came.

The siblings came together, grunting and moaning and squirting hot cum and magic all over each other.

“F-- fill me up, Shining!” Twilight moaned in between her cute little gasps for breath, riding high on her orgasm. The pulsing change in Twilight’s marehood, no longer leaking Pinewood’s seed but now eagerly accepting the addition of Shining’s cum into the swirling mess inside her womb, caused Shining Armor to bite down so hard on his sister’s neck that he could swear he tasted a little blood on his tongue. It didn’t matter, though, as the magical reverberation between the two ponies made it clear to him that she enjoyed the pain, letting him mark her like the slutty sex toy that she truly was. Little fireworks shot forth from both of their horns, lavender and magenta and other nearly indescribable ultraviolet hues that glittered and seemed to echo the powerful release that Shining felt himself give to his receptive sister.

At the same time, feminine wetness gushed forth from the hidden recesses of Twilight’s marehood, rinsing part of the previously-frothed stallion’s seed from her labia and then washing down both ponies’ hind legs in a hot slippery waterfall of marecum. The scent in Shining’s nostrils was erotically overpowering, a mixture of his own testosterone, his sister’s unbridled desire, and of course Pinewood’s dominance over the entire situation. The alicorn whimpered as she finished cumming, bucking against her brother in little squirts and gasps. “Don’t stop, please Shiny… don’t stop.”

It seemed that the initial feeding that Pinewood had given to Shining Armor, though not potent enough to fully put the unicorn in Pinewood’s control, had certainly had some kind of effect on how Shining Armor’s body and mind responded to demands like this. He climaxed for far longer than he’d ever recalled, pumping more and more of his seed into his sister until he felt his balls finally give up as they parked themselves snugly against his body, emptied and satisfied. His cock remained hard still, and he experimentally gave the member a few strong twitches inside Twilight’s depths. No more of his offering came out of his flared cockhead, but it still felt good to tweak and flex that pubic muscle while pegged so tightly inside his sister. She responded with a couple of undulating flexes of her own, the wet slurp of her outer labia like music to his ears.

“Nnaahh!” He grunted and nipped her playfully on the ear now, his sensitive cockhead almost stinging with the added stimulation of her last squeeze. “I don’t think I ever want to stop, Twily,” he whispered lovingly, then kissed her cheek and sighed. “I’m so happy that we could try this together.”

“I’m glad you enjoyed it too, Shiny.” She smiled back at him. “Truthfully, I guess there was always a little part of me that wanted to be with you like this… and now we’re more than just siblings.”

Chapter 3

Shining Armor smiled and kissed his sister lovingly on the lips from his position mounted on her weakening frame. “I wish we could stay like this forever,” he whispered, feeling his cock finally begin to soften just a tiny bit.

“Me too, Shiny…” she moaned into her brother's mane, though her body clearly began to twitch and tremble its way back toward equilibrium, tightening on Shining’s rod until he finally couldn't take the pressure anymore.

“Ahh, fuck!” he gasped into her tricolor mane, his cock slipping free of her outer lips as he nearly tripped backwards on his own hooves. He was forced to dismount the princess, and then he stood waiting there, looking at the cummy mess of her quivering marehood just inches from his face. He had an urge to bury his muzzle in those folds and get lost in the sticky wetness of his sister’s well-fucked cunt.

A slutty cough escaped Twilight Sparkle’s throat, but only a moment of awkwardness passed between the two.

“That was beautiful, my love,” intoned Pinewood from his vantage point on the bed. “Now that you have more cum filling your delicious sex-toy body, I want you to try the spell we discussed earlier. I know you have plenty of skill and mana for it.”

Shining Armor turned toward the earth pony, slightly confused. He almost opened his mouth to ask what spell Twilight might be using, but Pinewood’s commanding gaze made the white unicorn grind his teeth shut. Clearly this was something that Shiny was supposed to witness without giving his input.

“Um,” Twilight began, not sure exactly how to warn her brother while still obeying her Master. She decided that nonverbal direction would have to do. “Just…” she gulped, suddenly feeling somewhat… hungry and insatiable when looking at the chiseled jaw line of her white-and-blue unicorn sibling.

The princess slowly turned around, then hopped up on the bed in the clear space Pinewood had left for her. The green earth pony stood up expectantly to the side of the luxurious bed, watching as his beloved Twilight took a reclining pose on the sheets.

“Just take a taste,” Twilight said to her brother, lying on her back and spreading the messy beauty of her crotch wide for Shining to see. Her left forehoof traced its way down her downy chest until the soft fur below her belly parted so enticingly for his entranced eyes. She was far too beautiful for words, and the come-hither look in her eyes was all he needed.

He was hungry. “Uh,” the white unicorn mumbled as he leaned toward the bed, his legs finding a stable position between the floor and the mattress while his muzzle made a beeline for the double creampie of his sister's pussy. “Oh, fuck,” Shining groaned when his lips made contact with the alicorn’s twitching clitoris, and both ponies’ horns began to glow with a sensual aura. Shining felt his spiraled head-bone throb hard, as if Twilight was tying her own magical prowess to some essence that he'd offered her. It felt good, though, to keep sucking and slurping on her growing clit.

Shining licked, teased, and kissed his way down the outer lips of Twilight’s sex, cleaning any globs of seed that he found along the way. Some of it was familiar in taste, like when Cadance had made him clean up his own cum after their marital romps. Other sticky white strings were muskier, a little less salty, and most of all so intoxicatingly masculine… certainly Pinewood’s deeper deposit from earlier, scooped out by the flared ridge of Shining’s cock just minutes ago. And all of these sweet and creamy flavors were underscored by the heady aroma of Twilight’s ever-present lubrication, that morning-dew of feminine wetness that even now seemed to gush forth from the depths of her pleasure cave. He reached the bottom edges of her labia and cradled a tongue-full of the three lovers’ emissions, dragging his whole muzzle back upward through the mess while swallowing. In any other context, the slow and slimy trip down his throat would have made him rethink what he was eating, but to ingest this heavenly cocktail of fluids… it was so filthy and wrong as to make it irresistibly right. He ended up on her clitoris again, and with a suction that nearly popped his ears, began to polish that throbbing little knob in earnest.

“That's it,” she encouraged him, wrapping her hind legs around his head as he began to lose himself to the dancing button against his tongue. “Good boy, Shiny…”

While his thoughts swirled strangely, making Shining Armor moan and writhe unlike any masculine stallion before or since, Twilight’s clit continued to increase in size. Throbs and uncertain hip-thrusts pushed their way into the white unicorn's muzzle, and soon enough he couldn't even find the cum-filled entrance of her inner lips with his tongue. Those folds had seemed to seal shut, growing firmer and more desperate with every velvety heartbeat under his probing tongue.

“Hmm?” the unicorn grunted, pulling his lips away from Twilight's crotch inquisitively.

“Don't stop!” she moaned, pressing his head down with one hoof. A brilliant magenta flash suddenly filled the bedroom as her spell crossed its point of no return.

Shining Armor immediately recalled Pinewood’s rude insertion into his muzzle, because for some reason Twilight's clit was growing inch by inch into the likeness of a stallion’s veiny pride. Fuck, it really was a fucking cock, wasn't it? He wiggled backwards, trying to extricate himself before the swelling head of Twilight's clit grew completely into a pulsing rod inside his throat, but the alicorn's thighs were too tightly wrapped around his head.

What the fuck? he cried out, reverberating inside the minds of both Pinewood and Twilight Sparkle.

“She's using your own testosterone to try out masculinity for herself,” Pine explained. “Also, some of my dominant hormones are involved. Struggling will get you nowhere.” The green pony grinned, trotting around to stand behind Shining Armor’s rump.

“Hrg?” the white pony gagged, completely unprepared to have his throat fucked by his sister. The head of Twilight’s cock, though not as thick as Pinewood’s, pressed uncomfortably into Shining’s esophagus. He had no choice but to swallow hard, feeling a searing throb of pain rocket through his entire body. He’d timed it completely wrong, a rookie cocksucker mistake, and was paying the price now. Tears welled up in his eyes when finally the next pulse of his sister’s new member forced a wet glob of precum directly into his aching throat, lubricating the rest of her length and allowing her to hilt herself eight inches into Shining Armor.

“Celestia! Fuck! Keep sucking!” Twilight Sparkle moaned, her eyes rolling back in ecstasy. She could feel the tightness of her brother’s muzzle along every sensitive new inch of her stallionhood, and even though the fine lavender fur of her crotch now almost filled his nostrils, she felt the drive of her new cock begging for more. Deeper. She needed to be deeper inside him, and it was so tough to hold herself back for another moment.

Pinewood smirked and hopped up to mount Shining’s flank, bringing his teeth down gently on the white unicorn’s left ear while his veiny green monstrosity probed up Shining’s thigh and between the cheeks of his rump. “I’m so glad you decided to join us, Shining,” grunted the earth pony. “And I bet your ass will be almost as tight as your sister’s.” Pinewood knew the dripping faucet of his own eager precum must be coating the base of the unicorn’s blue tail with so much lubricant that it would trickle down onto the darker anal ring below.

And then, there was a loud squelching POP, and Shining Armor’s eyes widened when he felt the steely tip of the dominant stallion’s hardness find its mark and dig its way six inches deep with a single thrust. He was an anal virgin no more.

FUCK! bounced back and forth along the mental link between the ponies, as Shining felt his mind nearly overload with pain and pleasure alike. He’d never been taken this way before, though Cadance had helped him to experiment with toys sometimes. Something was different. Not just the throbbing insistence of the real thing currently violating his innards, but something different about himself. Was there some kind of thaumic reflection from Twilight’s spell? Was the tingling flesh of his backdoor somehow… more sensitive? More willing to be… prodded and…

Shining Armor felt the painful spasm of a gag build from his abdomen up until it made his whole body quiver and reject several inches of Twilight’s shaft. She kept him pinned just enough that her cockhead lay on his tongue, oozing salty liquid. He was barely able to breathe around it, blinking hard to clear the tears from his eyes. Then the pain began to subside, and a warm fuzzy feeling now radiated across his skin. He felt flushed, rosy-cheeked, and most of all ready for the promise of pleasure from the two cocks now spitroasting him.

“Good boy,” sighed Pinewood, letting his weight shift and pivot so inch by inch he’d slide into the unicorn. Simultaneously, Shining’s frame would be forced forward and down onto Twilight’s dick. “There you go, Shining. I knew you’d enjoy it, but that was an even quicker adjustment than I’d thought. Go on, try some motion.”

The purple pony opened her eyes again, looking down to watch the last couple inches of her newly created cock slip away into her brother’s throat. She exhaled a slow hiss through her teeth, trying to control her own breathing and keep herself on the slightly more relaxed side of the orgasmic climb. Now she caught Shining’s gaze as he experimented with his tongue, lovingly giving back to him her facial expression of bliss to show how much she was enjoying this treatment.

Though he was very much pinned between the two other ponies, Shining Armor was still able to fidget his body from side to side. He found that by arching his back, he could pull away from Twilight’s crotch slightly, and though her cockhead still plugged the entrance to his throat, he could do quite a bit of gymnastics in this newfound space with his tongue. Carefully he swirled the muscle around Twilight’s dick, tracing up and down a vein that seemed to pound hard with desire. He kept a close watch on his sister’s lovely face, trying his best to see her reactions and figure out what she liked. The fluttering of her eyelids was probably the best reward he’d ever had, and when he felt her hoof start to idly caress his mane he knew he was tickling a good spot between the stiff core of her shaft and the spongy cumtube that ran along its underside.

Pinewood slowly pulled himself backwards, savoring the way his newest conquest was just beginning to learn how to tighten or relax in response. He held his long green cock barely inside Shining’s ass, on the verge of popping out even, and squeezed his pelvic muscles for a few throbs in time with the thumping of his heartbeat. The stretched anal ring of that royal white rump below him squeezed back, as if begging him to stop the tease and get on with the fuck. Pinewood grinned. Soon, yes very soon he’d give that slutty stallion enough to make him walk funny for a week.

Shining Armor realized that he’d been holding his breath for nearly two minutes now, and though he could probably go longer with magic, he took this opportunity to back himself up two inches onto Pinewood’s cock. In the process his throat freed its tight grip on Twilight’s member, and he was able to take a few deep breaths while she gasped and squirmed under his muzzle. He continued his attention on the ridge of her cockhead and was rewarded with another delectable dribble of precum directly onto his tongue while he played with the sensitive opening at the end of her dick. Why was he acting like this? Shining hadn’t shown even half as much enthusiasm when he’d taken Pinewood’s cock into his throat, and here he was trying to earn high marks for effort and technique.

“Ohh, Shiny…” moaned Twilight Sparkle as she began to grind her hips up and down, her soft rump lifting away from the sheets before falling back down. She was tingling all over and her horn was glowing with a low steady burn, a fizzle of magenta light that illuminated the sultry features of her face. She traced the edge of her brother’s muzzle with her hoof until she could feel the way his lips slipped so wetly around her cock as she thrust upward, begging him to open his throat again so she could fuck him harder. “Deeper, again!” she gasped, unable to really make a complete sentence around all the elongated vowels that she vocalized. “Pleee-ease, Shiny!”

“I think you’d better ramp it up, boy. Your sister and I are getting a little impatient.” Pinewood waited until he saw Shining Armor’s chest expand with a deep breath of air, and then the green stallion suddenly thrust forward again. He grunted with pleasure as he felt the immediate warmth and tightness of Shining’s innards spasming around his length, but this time the unicorn took it like a pro.

Shining Armor pushed back hard against Pinewood’s crotch, humming happily around his sister’s cock. He felt so delightfully full, like this was something he’d been missing all his life. Grinding his belly against the silky sheets, he realized that his own cock wasn’t even hard! Sure, he had just finished unloading a huge load into his sister, but he was so incredibly turned on right now that it was surprising to find his cock soft and hidden within its sheath. He was leaking an unending stream of precum, though, lubricating the dark folds of skin there and matting the white fur of his belly. “Mmmff…” he moaned again, louder, sending a buzzing vibration into Twilight’s thick rod before taking another deep breath inward.

Twilight knew what that sharp inhale meant. He was ready for her to fuck his throat. She gripped his head between her hooves, forcing his muzzle down until she felt her cockhead pop through the muscles that separated his mouth from the deeper recesses of his esophagus. Fuck, it felt so good to just play with that barrier, even better because she’d already known for herself how painful and pressurized it felt to be the one giving the oral service to a well-endowed stallion. She recalled how Pinewood had abused her throat-muscles before, and, savoring the memory, decided to give her brother an equally advanced workout. She deserved no less than outright cock-worship on her magically provided member, after all.

Out… slurp… Shining Armor stared directly into his sister’s eyes as he swirled his tongue around her cockhead immediately after she pulled him up enough for him to do so. Then when he felt her push down, he swallowed hard to engulf her thick ridge with his throat.

In… throb… Twilight squeezed her thigh muscles around Shining’s neck and saw the rising up of tears in his eyes as his throat was forced to swell around the pounding veins of her shaft. He’d always been such a jock, and now to bring him down to her own level… Just a cocksucker. No dominance of his own. It gave her such a rush to share this intimacy with him, and then when she focused on Shining’s rump, getting so steadily reamed by her Master’s cock… Twilight Sparkle’s body flexed and strained, and she felt the beginning rumbles of cum pressurizing her heavy balls. Oh yes. She wanted to feed her brother such a thick load to reward him for being such a good little fucktoy for the two of them.

Out… Shining Armor simply couldn’t get enough. Sweet Celestia why did it feel so good through all the pain? His entire body was electric with pleasure, and Pinewood was still only giving him the first seven inches of that irresistible dark green tool. The unicorn swore he could feel every branching vein, every sliding fold of sheath skin, every delightfully hard nubby protrusion that crowned the thick head of Pinewood’s cock. And he loved it all, needed it all to slide in and back out, raking its way across his now-stretched innards, coating his intestines with the sticky sweet nectar of Pinewood’s balls.

The green stallion couldn’t stop himself from leaking precum if he tried. He’d found a good rhythm now, humping in and back out perhaps once or twice every few seconds, savoring the way Shining’s tail twitched and tickled his belly fur every time he plunged into his new little anal slut. So incredibly wet in that tunnel, it took every bit of his restraint to just slide in until he felt the resistance of Shining Armor’s deep inner ring. That second barrier could wait just a little while longer; he didn’t want to cum before Twilight did.

Of course, the princess was already nearing her point of no return. In, then out, then in again, her cock began to reach a new level of hardness, and its flaring head a new pleasurable level of sensitivity. In, out, in, out, in she directed her member into Shining’s throat. Though now she knew there would be a steady flow of tears from the pain she was causing his abused muzzle, she didn’t care. Out, in, out… then one last squelching in was tougher than before, and required more force from her hooves down on Shining’s head, and caused her to cry out, realizing she’d been holding her breath-- “Oh god, Shiny!” Twilight moaned, finally unable to hold back the impending torrent of seed now rising powerfully up her shaft. “Swallow it all!”

If the Princess of Friendship was adorable, beautiful, cute-- any number of words that had certainly been used to describe her unforgettable face-- now she could only be described as passionate. Her mane was messy with sweat so it clung to her slender neck. The campfire-like glow of her horn now burst forth with a brilliant firework of colors, some of them impossible neon blends of hot pink and ultraviolet. Her muzzle scrunched up with the effort of her orgasm, and she whimpered over and over in time with the squirts of her cum directly into Shining Armor’s belly.

The white unicorn, being so mentally linked with his sister through magic, felt his own pleasure spike at the same time as hers. Sparks of blue fire erupted in tandem from his horn, and he felt the unmistakable pulsing of his own pelvic muscles as he spilled his load directly onto the sheets below his flaccid prick. The fact that he couldn’t breathe at all didn’t bother him, and he strained his neck muscles hard in order to impale his throat as completely as he could onto Twilight’s spasming cock. His lips met the very base of her crotch, sucking and slurping and daring her to keep squirting rope after rope of thick cream into his throat.

Just moments after Twilight Sparkle and Shining Armor began their orgasm in unison, Pinewood felt the ricochet of muscle tightness bounce its way through the unicorn’s body and around the earth pony’s cock. Pinewood groaned and sped up his thrusts now, helping Shining to keep his muzzle fully stretched around Twilight’s purple tool while the green stallion knocked even harder on the tight inner ring of Shining’s intestinal maze. In, out, in, out… Wildly thumping heartbeats of all three ponies were pounding, pounding and yearning for release in their bodies and minds.

Now was the time to give him every inch.

In. And then even deeper in. Pinewood grunted with effort and shoved his way through that previously untouched tightness, and suddenly felt his own cock reach its fullest ever hardness as he flared wide inside the white-hot depths of Shining Armor’s ass.

“Hrg!” It wasn’t a true gasp, as that would have required air to escape from Shining’s lungs. Twilight’s cock was far too thick to allow that right now. But still the poor abused unicorn felt a searing pain inside him where Pine’s cock had brute-forced its way into a deeper and tighter secret of his belly. It hurt to push back, but that was what his body’s reflexes were doing now, rippling and pushing back to try to reject that baseball bat of a horsecock. But the round muscles failed to resist such a complete entrance, and when Shining Armor felt Pinewood’s balls slap wetly against his own, he knew he was done for.

On top of the mental and oral orgasm he was still receiving from his sister’s throbbing throat-fuck, Shining Armor felt his entire body reel hard from the first shivering pulse of pleasure of a true anal orgasm. He’d never felt like this before, tightening his rump muscles around the flared head of Pine’s cock and milking it for all it was worth. Shining felt the first hot jet of cream, a real stallion’s cream, paint the inner walls of his belly, and he bucked his hips with enthusiasm backwards another inch to tightly hilt himself as a lowly cocksheath around Pinewood’s amazing pleasure-stick.

“Fuck,” the green stallion growled, flexing his body backwards and feeling how his cockhead didn’t budge from the impossibly tight folds that pulsed around it. “Take it all, boy!” The second spurt of Pine’s seed was nearly a pint of liquid alone, and he was just getting started. He opened his eyes through the haze of orgasmic pleasure, and saw Twilight’s cock throb its own seventh jet of cum into Shining Armor’s throat. The unicorn was being filled from both ends now, and his belly began to swell slightly as if he’d just had a big meal.

Throb. Three, four, and five squirts of Pinewood’s powerful masculine flow now filled Shining Armor’s rump, and the hot liquid swirled around Pine’s cockhead, bathing him with his own passion in a slick stew of hormones. He felt the rising pressure inside Shining’s belly now, and with a hard thwick he pulled himself back just enough to unplug his flared cockhead from that second ring of Shining’s intestines. Six, seven, and eight more pumps of his cum later, and the amount of seed that filled the unicorn’s backdoor now surely neared a gallon, and it was clear there would soon be very little room remaining.

“Do you-- hhaaann…” began Twilight, trying to ride out the last few pleasurable throbs of her cock’s expenditure before she began to deflate in her brother’s throat, “need a break, Shiny?”

The white pony shook his head from left to right once, squeezing his tongue against the underside of her cock and swallowing the waning flow of her cum. Being a stallion himself, he knew that unless she got a huge influx of mana soon, her hardness would have to take at least a short break after such an explosive orgasm. He could handle holding his breath a little while longer, and the warm pool of his sister’s cream that filled his stomach now was perhaps around half a gallon. A lot, but still manageable. Not painful.

In his rump, on the other hand, Shining Armor realized that Pinewood’s cock was still pumping cum a full pint at a time deep into him. Over a gallon and a half now must have been forced into his intestines, and showed no signs of slowing. With his mouth still tightly wrapped around Twilight’s member, Shining Armor raised his eyebrows at his sister inquisitively.

“He won’t stop until…” Twilight explained, wondering if she should intervene and ask her Master to go easy on her brother for now. But then again, the white stallion seemed to be handling himself quite well, especially the emotional side of taking so much abuse from both ends. “Until he feels you’ve been trained. He loves to take a pony past the breaking point, to make you belong to him.”

Just then the pressure inside Shining Armor’s belly reached a painful climax, and he grimaced with the development of this new discomfort. Throbs of continually added cum now met with a tight cramping action inside his digestive tract as his body tried in vain to force over two gallons of cum to move back out his rump, but Pinewood’s cock remained diamond-hard to make a good seal against Shining’s anus. Only a tiny little dribble of white escaped between that veiny green monster and the spasming ring, and the pinned unicorn curled his legs beneath him to try and focus his mind on anything other than the pain deep inside. His belly was swollen now to nearly twice its normal size, and though he wanted so desperately to prove that he could handle Pinewood’s offering, he felt a reflex of sickness begin to overtake his entire body.

Seeing her brother struggle like this, Twilight was torn. On the one hoof she wanted to use magic to make it easier for him, but on the other, Pinewood wouldn’t stop until he’d truly broken Shining. So, much like confronting an issue head-on, she decided to ramp up the pain for her brother, to quicken the inevitable. She rubbed her own body up and down with her hooves, spreading her wings out and embracing Pinewood above Shining Armor’s prone body. She used every bit of her remaining magic to keep her cock hard now, and then she pulled herself back so her cockhead was freed from Shining’s throat.

The unicorn gasped for air, strings of cum hanging from his lips while his tongue mumbled something against the thick purple gag of his sister’s cock. “But I don’t want to be trained,” it sounded like he said.

“Too late for that, slut,” responded Pinewood, and he pushed himself forward until he popped through that tighter inner ring again, forcing the next few jets of his cum to flood the fucktoy’s upper intestine.

Gagging and coughing loudly, Shining Armor bucked back and forth, trying to pull away from Pinewood. It was useless, and Twilight pushed her cock again into his throat. This time he wasn’t ready for it, and both ends of his body reflexively spasmed to reject the cum from his body one way or another. There was simply no room left for it, and the leak between Shining’s anus and Pinewood’s cock became a steadier flow now, squirting slightly back out onto the green stallion’s thigh with every thick pulse he forced into the unicorn.

Shining Armor, the captain of the royal guard, expectant father, icon of masculinity… reduced to a blubbering red-eyed mess. The rivulets of tears that ran down Shining’s face now mingled with the overflow of cum from his lips, and visual stimulation for Twilight was enough to drive her to a small aftershock orgasm now. Just a few quick bursts of cum that alone wouldn’t be too much to handle, but with the overwhelming pressure already inside his belly, Shining simply couldn’t swallow it.

Heaving his abdominal muscles painfully, Shining Armor gagged and gagged and loudly gagged again, expelling a mixture of Twilight’s and Pinewood’s cum from his throat. It cascaded in a thick bubbly waterfall down his sister’s purple cock, and the wet slurping sounds of seed and throat-slime were exactly what Pinewood wanted to hear. The green stallion gave just a few more hard thrusts, each one accompanied with several mouthfuls of cum that overflowed from deep inside the unicorn up his abused throat like a lewd geyser to coat Twilight Sparkle’s belly and thighs. Perfect.

Finally stopping his several-minute-long orgasm, Pinewood moved his body backward and dismounted Shining Armor. Over a gallon of seed immediately rushed out from the gaping ring of Shining’s ass, before the unicorn whimpered and sat backward, trying to tighten himself back up. His belly was still swollen, and perhaps an equal volume of cum remained inside his body, sloshing around and aching a little less now that he’d given up on holding it all.

Shining Armor pulled his head up off Twilight’s cock now, and let the remaining mouthful of cum that had refused to stay in his belly fall down in ropes across her deflating shaft. Sheepishly, he tried wiping his muzzle, but both of his forehooves were already covered in cum so it was no use. He sat there for a moment, dazed and clearly unsure of what to do next.

Twilight gave her brother a knowing look. “Welcome to the club,” she teased him, cleaning his chin with her wing. The white goo on her feathers was certainly a good look for her, and for a moment Shining wanted to ask to cum on her body. But that thought quickly quieted itself when he caught Pinewood’s eye.

Shining Armor found it hard to keep eye contact with the dominant stallion. So this is what submission was like. Interesting. It was especially telling that he seemed to have an urge to clean both of the semi-erect cocks around him, and still quite strange to feel his own member so soft and hidden in its cummy sheath. Truly he’d have some deep thinking to do after this experience.

“Um… Thank you? Sir?” the unicorn tried, unsure of what to really say.

Chapter 4

Shining Armor blushed, his cheeks warming with a slight pink tint underneath the slowly cooling face mask of cum that soaked his white fur. Part of him wanted to pretend that this hadn’t happened, to try to go back to the way he felt before tonight. He was captain of the royal guard, after all, and expecting a baby in just a couple of weeks. He had all the typical boxes checked when it came to masculinity and dominant strength. And here he was, trying to come to grips with the feeling deep in his gut that said yes to all these new emotions of quiet servitude, yes Sir I want you to be happy before I worry about my own needs.

No, he corrected himself. A little more saliva welled up underneath his tongue. I needyou to be happy. Fuck my own needs. Fuck me.

Twilight sensed the conflict brewing in her brother’s heart, and she winked knowingly at Pinewood. “Hey Shiny, want to take a shower with us? I can show you the best part about spending time with our Master.” As she said these words so soothingly, she touched Shining’s cheek with her hoof, wiping a little cum off her brother's lips, and reinforcing the positive thoughts with her own gentle caress.

Pinewood opened the door to the bathroom and held it open with one hoof while he looked at Shining Armor with a kind, reassuring smile. “Come on, boy. Let’s take a little break together.” The green stallion, though glowing with satisfaction, still had a heavy cock that bounced back and forth underneath his belly.

After giving her brother a slow and loving kiss on his cum-stained lips, the princess stood up. Her own magical horsecock was spent, but she clearly retained the concentration and strength to keep it half-hard as she trotted toward the shower. As she passed Pine, she slowed and swung her rump back and forth with her tail held high for his enjoyment. “Just follow my lead, Shiny. Master would love to see you give in and enjoy yourself, OK?”

It took a little more effort for the white stallion to stand. His body was swollen with cum, and as he rose to his hooves there was a rumbling slosh of viscous fluid inside his belly. He looked at the floor, full of shame that he’d been so wanton and receptive. And yet it gave him a strange sense of pride, that he’d been able to take as much as he had before finally expelling the overflow of seed. There was no discomfort now, though his stomach protruded with the gallons of testosterone-laced cream… perhaps that was part of the magic of Pinewood’s dominance. Shining Armor’s entire body was tingling with pleasure, and it felt perfectly natural for him to imitate Twilight’s slutty walk into the bathroom. He even lifted his tail as he passed Pine, presenting his cum-splattered rump to the dominant stallion as if to thank Pine for teaching him the true purpose of that sore round muscle between his firm white ass cheeks.

“Like--” stammered the unicorn, looking back over his shoulder, “like this?”

“That’s perfect,” replied Pinewood, and he gave Shining Armor a healthy smack on the cutie mark with his hoof. “I’m sure you’re used to being the one calling the shots at home, but when you’re with me, I demand nothing short of full submission. I can see that won’t be a problem, but we’ll be ramping up your training pretty quickly. I trust you’ll be a quick study just like Twilight was when she offered herself to me.”

Shining Armor gulped and nodded quickly. “Yes, Sir.” It wasn’t that he was afraid of pain, exactly… the unicorn was perhaps more afraid of how far he was actually willing to go. This side of him was still so new and unexplored, and so far it had turned out to be so fulfilling, so fun to let Pinewood direct his body and use him like a toy. What would his wife say, to see him being so meek like this?

Twilight had already stepped into the luxurious shower ahead of him. There was plenty of room for all three ponies to stand and turn around each other comfortably, and though the water wasn’t running yet, there were multiple shower heads embedded in the ceiling so it would be easy to clean up.

Shining’s horn lit up as he used his magic to turn a nozzle, but he had scarcely opened it halfway when Twilight touched his horn with her hoof, shaking her head. “No-no, big brother. When you belong to Master Pinewood, he owns your magic as well. You’re not to use it unless given explicit orders.”

“She’s right,” Pinewood agreed, turning the water back off with his hoof as he stepped into the shower behind them. With a gentle push, he nudged Shining Armor into the corner of the tiled shower. “On your knees, boy.”

“Why?” asked the unicorn, though he did slowly kneel until he was laying on his belly and ankles.

“I like your curiosity, but it’s getting in the way of proper training. Twilight, go grab me a spare collar and leash.”

“Yes, Sir.” She trotted out and returned shortly with a simple leather collar that was attached to a short black leash. “Shall I put it on him, Master?”

“Go ahead, darling. I think you’re doing a great job of teaching him. This doesn’t elevate your status, though. It just means he’s still a few levels below ‘slave’ in my mind, at least until he proves himself.”

Shining Armor’s heart beat faster when he felt his sister fasten the collar around his neck. She wasn’t apologetic, just quick and methodical. “Now stand up, slut,” she commanded him.

“I thought he said--” Shining was confused, but the quick jerk upwards on his brand-new collar didn’t leave any room for doubt.

“I said up, slut!” Twilight grinned, clearly enjoying herself.

Coughing and shaking his head, Shining Armor rose to his feet. “Oh, I get it. Practice?”

“I didn’t ask you to speak. You are to address me as Mistress, got it?” Now there was a fire in Twilight’s eyes, and her thick cock throbbed hard underneath her.

“Yes Mistress!” The unicorn gulped at this unexpected streak of dominance from his sister. Sure, to everypony in town she was the Princess of Friendship, but to him she’d always been just a little tag-along. The role-reversal was spicy and enjoyable, like a rush of excitement over the crest of a roller coaster. Or maybe that was the belly full of cum. He could hardly tell the difference at this point, to be fair. His body was buzzing more intensely than a feline in a field of catnip.

Shining Armor stood patiently while Twilight circled him slowly, her eyes tracing their way up and down his desecrated fur with delight. If she was trying to make him feel humiliation, it was working. He felt more and more naked with every passing moment, and his eyes darted down to see her magical cock back at its full hardness, one pulsing vein standing out among the rest as she flexed her pelvic muscles.

“Do you like peeking at cock, boy?” she asked him with a grin, jerking the leash slightly.

“Yes, Mistress,” he replied almost instantly. He watched as her abdomen rippled with a little exertion, and suddenly a glistening pearl of precum appeared at the tip of her purple member, growing in size gradually until the surface tension lost out to gravity. The mouthwatering drop fell, ever so slowly, until it dangled halfway to the floor of the shower.

“Then say it. Confession’s good for the heart.” This time it was Pinewood speaking, just inches from Shining Armor’s ear. The white pony almost jumped. He’d been so focused on watching his sister that he hadn’t noticed how close Pine was standing.

“Yes Sir. I like peeking at cock.” They were right, Shining thought; it did feel good to say it out loud like this. He tested the logical next step. “I like touching cocks, Master.” And he knew it was true.

“Then you may ask your sister for permission to touch her cock.” Pinewood was practically licking Shining Armor’s ear, he was so close. The green stallion inhaled deeply, sensing the way the collared unicorn trembled and hesitated before him. It wasn’t quite fear, no, it was more like respect, as if Shining wanted so desperately to please Pinewood that it paralyzed him. Pinewood’s lips just barely grazed the soft inner skin of Shining’s ear with a hint of a kiss. “Go on, slut. Beg.”

Shining let out a slow exhale, closing his eyes for just a moment while he savored the touch of his Master’s lips on the sensitive membrane of his ear. Yes, it felt so good to give in like this. Slavery was some kind of odd freedom. He didn’t have to make any decisions for himself. Just say yes. Ask for more. Yes. He opened his eyes and spoke.

“Please, Mistress, may I touch your cock?” She was no longer his little sister Twily. She was the cock-wielding highest-level Alicorn who would train him to give pleasure. He wanted to show just how capable he could be, and bring great pleasure to their Master Pinewood.

“No,” came her quick reply. “First you must prove you understand just how far below me you are, slave.”

Shining Armor’s mind began to race through his options. He wasn’t allowed to speak without being asked first, but he hadn’t been given any instruction on his next task. Just that he needed to lower himself. Tentatively he lowered his head, bending one of his front legs carefully in a kind of curtsy.

“May I… May I kneel before you, Princess? Please?”

Her smile showed that he was on the right track. “Yes, boy. All the way down on the floor now.”

Keeping his head bowed, he folded one leg at a time underneath his body. It was easier said than done, with the swollen bulge of his belly in the way. Finally he was resting on the hard floor, his muzzle against the tile a few inches from Twilight’s hooves. He realized the tiles were relatively warm compared to the cool congealed globs of cum that remained on his face. But instead of shame, this sticky white reminder of his submission only brought about a strange pride inside him. He was coming to terms with the fact that he actually felt happier and more fulfilled like this, looking up at two hanging horsecocks, than he ever had in the rest of his life so far. It was absolutely electrifying.

“Belly up,” was Twilight’s next command.

“Yes Mistress.” Shining immediately complied, though it was slightly uncomfortable to feel his backbone rubbing on the floor of the shower. His distended stomach rumbled and shook as he presented it to both standing ponies. He blushed when he realized that now they were looking at the darker skin of his crotch and smiling at how his cock was still half-hidden in its sheath, as submissive as the rest of his body in the presence of such dominant instruction.

“Look at your own soft prick,” ordered the Princess. “Why isn’t it hard? Aren’t you enjoying this?”

He obeyed, looking around the bulge of his belly to peek at his own pitiful crotch. Both of his balls together were still smaller than one of Twilight’s heavy-hanging eggs. And Pinewood’s astounding cum-producers were several sizes larger yet. “I am enjoying my training, Mistress, very much. But I guess it’s easier to stay focused on your bodies rather than my own pleasure.”

“Good answer,” said Pinewood. “Your pleasure is always lower in priority than your Master’s. As a slave, your dick should be soft unless I command you to get hard. It’s probably not easy for you to do so without a little bit of stimulation, so during your training you may use your hoof if necessary. But your goal should be ultimate control of all of your reflexes, so that your heart rate, breathing, arousal, and yes even orgasm are all at the immediate command of your Master’s desire. Do you understand me, slave? I own you, body and mind and soul.”

“Yes, Sir. Thank you for this opportunity to serve you, Master.” Shining Armor truly meant it, and all doubt left his mind. He really wanted to reach that state that Pinewood was talking about, to be nothing more than an object for pleasure, a well-trained and proficient sex slave whose every moment was dictated by the whim of the greedy lecherous pinnacle of masculinity that was Pinewood.

“Good. Now I’ve already marked you with my cum, so the rest will be easy. Ask your Princess for her piss.” Pinewood grinned, waiting to see Shining’s reaction.

Surprisingly, there was only the slightest flash of hesitation on the unicorn’s face before he looked up into Twilight’s beautiful purple eyes. “May I have your piss, Mistress?” While he hadn’t really made it a habit to play with his own yellow water, there had certainly been times in the Royal Guard when questionable hazing rituals had made the steamy liquid a central focus in the games they’d played with each other in the stallion’s locker room. And there were the times when Cadance had been in heat, that he’d found her scent so intoxicatingly attractive that he’d begged for a chance to sip from the hot fountain of his wife’s pee. Now he wondered if Twilight’s flow would smell feminine or masculine, taste salty or sweet or bitter or clear.

She walked over her brother’s body so her hind legs straddled his cum-covered face. Closing her eyes and taking a deep breath, she started to relax that muscle inside her. Slowly, gradually she felt the warm pressure find its way past her inner valve and begin to rush through the tube of her cock. The magical rod was still rock hard though, so instead of hitting Shining’s face, the sudden flow splattered directly onto the unicorn’s belly. It made a wonderfully room-filling sound: thousands of heavy yellow raindrops pounded his body that was stretched taut like a drumhead with its full load of seed.

Twilight Sparkle moaned as she relieved herself all over her brother’s belly. There was no controlling her flow, and it sprayed hard in a single thick stream that widened slightly with its own pressure just before it hit his belly. Shining Armor inhaled deeply, watching the yellow liquid infiltrate his white fur. True to her unique nature, the Princess did indeed smell feminine at first, like the piss of a mare at the peak of heat. And then underneath that floral note, probably enhanced by her magical incorporation of Pinewood’s testosterone and whatever energy she’d taken from Shining, there was the darker musk of masculinity. It had the scent of a cock that had just bred a receptive hole.

Shining Armor’s mouth opened wide and he tried to stick his tongue out to catch a few of the second-hand splashes that bounced from his belly button. One or two salty droplets hit his lips, and he lapped them up quickly with a little grunt of happiness. Fresh piss never had the stale odor of an dirty stallion’s locker room, but it was hot and sweet and most of all reinforcing of his desire to prove his position at the bottom of Pinewood’s pecking order.

“It looks like he wants more,” Pine said now, stroking Twilight’s wings with his hoof. He guided the Princess a couple of steps backward so her firehose-like flood would at least halfway catch the unicorn’s muzzle.

“Yes, please Mistress--” Shining hardly got the words out when the high pressure flow hit his tongue square on and immediately filled his mouth to overflowing. He gulped down what he could, feeling the warm offering slide effortlessly down his throat to mingle with the cum she’d fed him earlier. He left his muzzle wide open now, letting the sound of the golden water’s flow fill his head with a peaceful reverberation. He closed his muzzle and pushed the pint of collected fluid back out so it cascaded across his lips and trickled into his nostrils. There it was a little more acrid than he could take, and with something between a cough and a sneeze his body cleared his nasal passages. He’d managed to block the backsplash with his hoof though, so it was mostly contained to his own face.

“Hah. You really do enjoy degrading yourself like this, don’t you?” mused Pinewood, taking in the beautiful scene while he felt the insistent pressure in his own bladder begin to grow.

“Yes, Sir,” Shining gargled again, swallowing a second big mouthful of his sister’s piss. The flow didn’t show any signs of slowing down, and while the majority of the yellow liquid was draining quickly, Shining could feel that he was almost completely drenched from head to tail. His back was submerged a good half inch in the swirling flow. Though the mud-mask of cum he’d previously earned had begun to dry before they’d started the water-based training, it began to loosen now with all the hot pressure of Twilight’s indiscriminate aim. He felt the smaller globs first start to remoisten, and then slide free of his fur. Then before he knew it, the tacky big ropes of seed that had once draped across his neck and mane were stringy and stretchy again, tugging away with the flow of piss until they slurped their way down the drain as well. He almost mourned the loss of the tasty white treat, but knew there would always be a chance for more.

What was slightly more alarming was the fact that he was enjoying this so much that he could feel a stirring in his loins. As he alternated between swallowing and inhaling the heady scent of his sister’s unending shower, he knew his cock would soon peek out of its sheath. And Pinewood had said that he should stay soft unless directed. Shining tried to focus his thoughts, but he was woefully inexperienced in reducing his arousal. All of his previous experiences as a dominant stallion had been such that his erection wouldn’t be more than a mild nuisance at times, and in fact a reinforcement of his stature at others. Now it could get him punished. And the thought of punishment in his submissive mindset was only raising his arousal more. Fuck.

Pinewood’s watchful eye noticed the head of Shining’s cock flop free of its protective fold of skin and continue growing to nearly full hardness. Pine idly regarded the dark tube of meat as it rested against Shining’s rounded belly. “Well well well. What do we have here?”

“I’m sorry Sir, I didn’t mean to get hard without permission,” sputtered the unicorn with his mouth half full of piss.

“Hold on, Twilight.” Pinewood’s command caused the Princess to immediately halt her flow, though it made her squirm slightly and squeeze her thighs together with the effort.

Pinewood walked around Shining Armor until he had the unicorn’s skyward-spread hind legs right in front of him. The green stallion lifted one hoof and placed it gently on Shining’s belly bulge so it squished a little yellow rivulet from the soaked fur.

“It’s good that you’re enjoying your training. I want you to know that I’m glad this will be easy. But that doesn’t mean you can bend the rules. It’s crucial that you learn to control your body so that you can be a true slave for me. So when I do this, you should not feel like it is a punishment. It is only to help you serve me better.”

Pinewood’s voice was gentle, careful. Soothing. Almost hypnotic. Already Shining Armor found it easier to focus on the peaceful way Pine’s hoof caused a warm pressure in his belly, rather than the tingling in his crotch. “Yes Sir,” replied the unicorn.

Pine increased the pressure on his hoof now, watching Shining’s face closely until he saw the hints of discomfort in the furrowing of the unicorn’s yellow-stained brow. “Part of your training is emotional, remember. You should be giving your mind freely to me, and I want you to be overwhelmed with shame and humiliation right now. Tell me when it’s working, slave.” And he pressed harder still.

“It hurts,” Shining tried to explain, knowing that his Master wanted a deeper confirmation. “My-- my body hurts because you gave me more cum than I could hold… at least at first… and then I wanted more, I really did want more, Sir. I wanted more and I didn’t know why… I didn’t know why I wanted to take more than my body could hold…” The unicorn groaned as he felt the humiliation wash over him. And the pressure of his Master’s hoof on his uncomfortably full belly only increased through his rambling confession.

“Look at me when you say these things.” Pinewood was clearly enjoying this, his dark green member flexing up and down as it began to leak a steady dribble of clear precum on the shower floor. “I find that it helps my slaves to come to terms with the depth of their dedication.” Pine shifted his weight slightly, with every few seconds increasing the pressure on his slave’s belly.

Shining did as he was told, looking directly into Pinewood’s eyes. He saw his own reflection in those deep pupils, saw his body so physically degraded inside and out, and began to feel tears rising. He was clearly close to an emotional breaking point. “I-- and then I guess I realized that the reason I wanted more was that I knew I didn’t have a chance of besting you, or even equaling you, Sir.” Shining was sniffling now, his yellow-stained cheeks glowing with the blush of strained sobs. “And then I realized that my best chance of ever feeling fulfilled was to live up to the expectations that you set as my Master.”

Meanwhile, the mixture of emotional torment and physical pain was doing quite a good job of helping Shining Armor lose his own erection.

“I mean, look at me. I thought I was a little bit above average before I met you, but that was clearly a lie. I’ve been deluding myself into thinking I was a stallion. I’m just a slave. Please, Sir… Please let me satisfy you?” He wasn’t saying it so the torture would stop. He genuinely couldn’t stop staring at Pinewood’s shaft now, his eyes hungrily tracing up and down the bulging veins while he licked his lips. The only thought remaining in his head now was the way he’d feel after swallowing another load of cum. The promise of satisfaction at a job well done.

“Are you willing to go above and beyond your own physical abilities for me?” Pinewood asked, pressing harder and harder still. “And your magic too, that’s just an extension of my command?”

“Yes Sir, anything for you Sir.” Shining was forced to breathe quick and shallow now, with the cum in his belly threatening to bubble up his throat in between gasps for air.

“Then get to sucking, slave.” And Pine removed his hoof from the unicorn’s belly.

Shining felt so good to hear those words. More than just the relief from pain in his gut, but the indication that he’d passed this phase of his training. “Thank you, Sir!” He quickly scrambled around, kneeling under his Master’s standing body so that he could latch his lips on the slippery head of Pinewood’s cock. It left his rump angled upward right in front of Twilight’s muzzle.

The Princess waited patiently for her Master to get into the rhythm of his blowjob, though her cock began to bounce up and down and leak its own stream of precum as she watched her pathetic brother humiliate himself on the pissy floor of the shower.

Shining slurped with gusto, gradually replacing the lingering salty taste of Twilight’s piss with the sweeter, stickier flavor of his Master’s precum. And oh, god, there was so much of it! He swallowed every drop that oozed from the sensitive hole at the tip of Pinewood’s cock, and dove into that little opening with his tongue to coax more out.

“Twi--” gasped Pinewood, clearly enjoying the thirsty attention on his dick, “do whatever you want with his rump. You’ve-- Fuck yes, good boy! -- You’ve earned it, love.”

She leaned forward, trying to savor the moment, but she was hungry of her own accord. Not only was there a delectable string of Pine’s cum that snaked all the way from Shiny’s tail all the way down his inner thigh, but she knew she’d need a fresh influx of masculine energy to keep up her magical stallionhood. And it felt far too good to let it subside just yet.

Twilight Sparkle dove into her brother’s rump, grinding her muzzle hard against the sensitive ring of his outer anal muscle and moaning at how it immediately twitched and tightened in response to her kisses. It smelled so good, mostly of her Master’s seed but also with a slight undertone musk of Shining’s sweat. She loved that day-old musk that stallions got. It wasn’t dirty, really, just rich in pheromones and hormones and whatever else it was that made both sexes crazy with lust. She had a hypothesis that the scent of mares in heat wasn’t just to attract sexually mature stallions, but also to drive other mares into that competitive spirit, to ensure that lust began to overcome logical reasoning.

And her brother’s scent was changing right under her nose, too. Just as she could tell that her own balls were heavy with the testosterone that Pinewood had magically bestowed, Shining Armor was undergoing a transformation of his own. His ass lips were far more responsive, puffy, and filled with sensitizing blood vessels than any stallion’s rump had a right to be. She grinned and continued to eat him out like he was a mare, running her tongue up and down the outer rim of his crack and then diving deep inside the welcoming depths to steal a warm mouthful of Pine’s cum. It was so delicious, creamy, sticky... everything that made cum irresistible. And it was all hers. She could feel Shining try to tighten his muscles to stop her, but her tongue was stronger.

Shining Armor had unconsciously begun to find a rhythm in his head-bobs, noisily smacking his lips on the upstroke as he quickly sucked in a little air. Then he plunged back down again, his tongue finding the sensitive medial ring of Pinewood’s cock just as his throat tightened up to prevent the entrance of that thick green head. He knew that speed and enthusiasm for the first half of this behemoth wouldn’t cut it. Pine would certainly expect him to completely impale himself.

But-- and his head was clouded with the pleasure Twilight was giving his rump, finding little sensitive folds and wrinkles just inside his cum-filled ring-- he didn’t know if he’d be able to do it without a little help. His neck was just at the wrong angle, and he knew that too much more of this would start to cramp his shoulder. That thought got pushed back out of his mind just as quickly as it had appeared. He doubled his resolve. He wanted to show off.

Adjusting his hooves while keeping the leaky head of Pine’s cock inside his muzzle, Shining found a slightly different position. Now he could get that extra bit of leverage. He could ignore the mild pain in his joints. His body belonged to his Master. He bobbed his head forward again, wincing slightly when the head of Pinewood’s cock bounced off the sore muscles that guarded the deeper tunnel of his throat. Ow. Try again.

Twilight sensed that now was the time to ramp up her analingus to a new intensity, and thanks to the refresher of a few swallows of Pine’s cum, her magic was at full strength. Moaning and focusing her mind, she dug her tongue as deep as she could inside Shining’s warm ass-cunt. At the same time she created a soft, pliable ring out of magic that slipped around her brother’s balls.

“Hmmf?” the white stallion interjected, with just the slightest hint of hesitation in his tongue’s motion.

Pinewood growled and stepped forward with two hooves, shoving his cock deeper into Shining’s throat suddenly. “That’s it, just swallow harder. Good boy.”

Twilight grinned and gave a slight nip with her teeth on the fleshy white mound of her submissive sibling’s cheek. When she felt him squirm again, trying to get his throbbing anal muscle back in range of her tongue, she let out a mischievous little laugh. “What do we say, slave?”

“Please!” he cried out, just barely intelligible around the sloppy wet rod that threatened to completely choke out his ability to breathe. “More!” His front hooves clopped hard on the wet shower floor.

Twilight and Pinewood locked eyes with each other as they both rammed forward. The purple princess suddenly found her muzzle completely surrounded by the show-quality globes of her brother’s rump, her sensitive tongue nearly six inches deep inside his cum-filled hole. And it was heavenly, that pulsing mess of slippery folds that held a mixture of her Master’s fluids and her own. She slurped deeper and deeper, coaxing mini-orgasmic contractions out of Shining’s body, swallowing every glob and dribble that he could no longer hold tightly inside himself.

Fuck… Fuck fuck fuck FUCK!

Meanwhile Pinewood groaned and felt a dam burst inside himself, like a geyser of hot steam-pressurized water that had nowhere to go but up and out. Cum quickly flowed in a sticky torrent, swelling the thick tube of his urethra and forcing the seal of his flared cockhead to mate perfectly with the deep clenching muscles of Shining Armor’s throat. He could hear no sound now but the pulse of his own heartbeat, for that rarefied moment of orgasmic pleasure as he felt himself go dizzy with excitement, his vision filled with the flailing motions of Shining’s mane and tail in front of Twilight’s ecstatic face.

Shining’s own orgasm, Sweet Celestia I’m going to get in trouble for cumming too, overtook his entire body. He shuddered and felt the tingling of his skin reach an almost painful crescendo as his half-soft cock pulsed out a pathetic imitation of Pinewood’s thick creamy flow. The biggest difference was how his small volume of slave-seed immediately mixed with Twilight’s residual piss and was lost down the drain. Sad. He would have liked to clean up his own mess… just another sign of his programming as a submissive slut, perhaps.

Gulp, gulp. Gag, swallow, gulp, and yes gulp again. Thank your Master for his gift, thank Him with your throat the only way that you know how, thank Him and beg for more, beg for this moment to last forever!

Shining must have swallowed twelve, thirty, a hundred? Who knew at this point. Certainly dozens of fresh jets of cum had coursed their way straight through the dynamic flexing tube of his neck and directly into his stomach to meet with that slutty salty mess of fluids already swirling around inside.

After a moment or so, Pinewood’s throbs began to subside, and Shining Armor found himself snapping back to the present. The white pony gulped a few times, thinking how strange it felt to consciously control those otherwise-involuntary muscles. They were certainly milking his Master’s rod automatically, just seconds ago. He looked up at the green stallion’s face, knowing there would be no way to hide his shame. But while Pine’s thick flared cockhead still plugged his throat, Shining was forced to simply look at that commanding masculine stallion’s upper body from below.

Twilight licked her lips and sat back on her haunches, sighing loudly. “Sir, I think your newest slave still has trouble understanding that you control his every move.” She grinned and slid one hoof up her own flagpole of a horsecock. “I can tell you came, big brother. Just from the way your tight hole spasmed around my tongue.”

Shining Armor’s training was certainly coming along, mentally. He immediately nodded, tears welling up in his eyes as he began to imagine the punishment that might come. If only he could control the reflexes of his fucking balls.

“Shh, shh…” Pinewood kept his soft yet baseball-bat-length meat stick still firmly plugged inside the unicorn’s throat. “I know it’s all still so new and exciting for you, but we’ll figure out a way to fix you yet. I think maybe if you meet one of my most dedicated slaves, you’ll learn by watching. Perhaps it’ll be just the idea of seeing my cock deep inside a pony more… submissive than you? You’ll have no choice but to lose that, hmm… last… shred? Is that the best word for it? Of your masculinity. We’re close, I can tell.” Pine winked at Twilight. “You remember Sparkchaser, don’t you?”
