Incestuous Pony Antics (w/ self insert OC)

“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.
