18th Hatchday

Spike tried to hold in a moan as Cadance’s hand brushed against the tip of his cock, the soft fabric of his briefs rubbing the sensitive head of his rigid dragonhood and blasting his nerves with pleasure the likes of which young dragon had never felt before. He had ‘taken care’ of himself in the past, plenty of times, in fact, but this… THIS was something else entirely. It was as if every sensation was amplified thousands of times over, just the simple touch of Cadance’s fingers against his boxers enough to cloud the dragon’s mind with bliss. As such, he found himself having some trouble responding to Cadance’s question.

“Buh… huh?”

Cadance giggled, playfully rolling her eyes at the dragon’s reaction. ‘Boys… just a little fondling and their like putty in your hands…’ She wrapped her thumb and finger around the top of Spike’s shaft, forming a ‘C’ shape around the smooth contours of the draconic member, a pleasing warmth radiating through the layers of cloth that separated her hand from his crotch. Cadance’s eyes gradually widened as she traced the thick cylinder of flesh down the dragon’s pants, marveling at how it seemed to keep on growing as she rubbed it. ‘Spike certainly is packing!’ She paused as, finally, she got Spike to let out a moan.

“I said, how much do you know about sex?”

Spike clenched his eyes shut, fighting against the pleasure battering his brain in order to form a coherent thought. “Ah! Mmm… w-what do you m-mean? I know what s-sex is, if that’s whaah… what you’re asss-king…”

Cadance glanced over at Twilight even as she continued stroking the dragon’s pride, smirking at the mare across the table. “Told you so.” Twilight gave her a sheepish smile, blushing either from embarrassment or from the continued ministrations from the stallion standing behind her.

Spike looked across the table as well. “Huh? W-what are you talking about? Twilight?”

Cadance pulled her hand from the dragon’s pants, returning to his chest to once again rub his smooth scales and give the quivering dragon a chance to recuperate. “Well, Twilight’s been a little… worried about you. She figured that, since she neglected to give you ‘the talk’ “ - she paused to glance at the mare in question once more, Twilight sinking down in her chair in an effort to hide herself - “you wouldn’t even know what sex WAS.”

Shining Armor chuckled, continuing to rub at his sister’s breasts as his other hand kept rubbing her farther south. “Kinda ridiculous if you ask me. Cadance and I had already ‘hooked up’ before I ever got the talk from my dad. If you know what I mean…” He pulled his hand from underneath Twilight’s skirt, Spike blushing as he watched a strand of something break apart between the stallion’s fingers. “Even little ol’ Twilight here “ - he gave his sister a pat on the back - “was doing ‘scientific research’ on me before being taught the birds and the- oof!”

Twilight elbowed her brother in the stomach, causing the stallion to keel over in pain. “Shining!”

“Ugh… what? Was it something I said…?”

Cadance giggled as her husband recovered, rolling her eyes at the siblings’ antics. She turned her attention back to the dragon sitting before her, hugging him from behind as Spike’s frayed mind tried to process what Shining had said. “What I mean to say is, have you ever had any… sexual encounters with somepony else?”

“He better not have!” Spike jumped when Twilight’s fist hit the table, glancing over at the mare as she pointed at him with a burning glare in her eyes. “If he did, he was underage! I swear to Celestia, Spike, if you even THOUGHT about doing something like that...”

Shining winced as he straightened himself out, arm over his stomach where Twilight had hit him. "Hypocrite..."

This time he would have to take a knee as Twilight struck him in the same exact spot.

Spike waved his hands in front of himself. “N-no! I haven't had sex yet… just, you know, rubbing myself and stuff…” The dragon didn’t think the blush on his face could get any brighter; here he was, on what he thought would be a nice, calm eighteenth birthday, talking to his family about the fact he masturbates! ‘This is NOT how I thought today was going to go…’

Spike covered his face with his hands, hoping to hide his humiliation from the ponies in the room. He peered out from behind the protective barrier of scales when Cadance began rubbing his back, the Alicorn leaning over to whisper in his ear. "Don't be embarrassed, Spike. It's perfectly normal for you to be doing that. In fact, it would be strange if you didn't!" Her other hand continued to draw circles on his chest, the dragon shivering from the light contact of her fingertips against his scales. "But, that being said, " - her fingers began heading back down his body, Spike tensing up the closer the mare got to his waistline - "doing it by yourself is NOTHING compared to the real thing, as I'm sure you've noticed."

Spike gasped as her fingers grazed his shaft once again, absentmindedly rocking his hips against her as she palmed his still-hidden cock through his pants. "Uh-huh... your h-hand feels a-amazing!"

Cadance giggled, both at the compliment and the fact that, as she pulled her hand away from the dragon's crotch, he actually whined in disappointment. "Thanks, but trust me when I say there is SO much more to the world of sex. So many things that would just blow you away..." She walked around the chair to stand in front of him, placing herself between him and the table. With half-lidded eyes she placed her hands on the armrests on either side of the dragon, leaning in over his lap and giving him a perfect line-of-sight down her dress at the dark crevice of her breasts. "And I'm here to show you as MUCH as I can..."

Spike had to close his eyes as his twitching dragonhood throbbed inside of his pants, straining against the cloth prison containing it in an attempt to break free. Cadance continued leaning forward, placing her head next to his and her mouth adjacent to his ear. With a breathy whisper, warm air brushed across the dragon’s ear as she said, "Me, you, Shining and Twilight... all four of us are going to head on up to the bedroom " - she reached underneath herself and patted the large bulge in the dragon's pants - " and we're going to give you a… hands on lesson on everything we know. Sound good?"

Spike found he couldn't formulate the words in his mind, simply settling for violently shaking his head up and down to express his agreement. With one final pat between his legs, Cadance pulled away, making sure to stand up slowly to give the dragon one final look at her ample bust. Spike simply stared at her as she smiled and patted him on the head. "Good boy..." She turned towards the pair of ponies across the table and clapped her hands to get their attention. "Twilight, Shining, let's head on up and get a little more... comfortable."

Spike turned towards them as Twilight answered her sister-in-law with a moan. Shining had both his arms wrapped around her and was cupping each of his sister's breasts through her dress. He had latched onto one of the mare's ears with his teeth and was lightly tugging on the sensitive appendage to make his sister groan. With his wife's call Shining pulled away, leaving Twilight to recover in her chair for a moment. He smirked at his wife as his sister took a moment to regain her breath. "Yeah, I think Twilight's ready to take this upstairs..."

As Shining helped Twilight up Cadance did the same for Spike, the dragon blushing as his erection formed an obvious tent in his pants as he stood. Cadance gave him a pat on the back and motioned him to follow, the dragon dutifully obeying the Princess’s command as the she made her way towards the door. As he passed the chair Twilight had been sitting in Spike saw a small puddle glistening in the light. He caught a whiff of something coming from both the chair and the two mares in front of him, something strong that, for some reason, brought heat to his face and made his cock throb in his pants.

He nearly shrieked when Shining suddenly wrapped an arm around his shoulder, the stallion patting him on the chest with his other hand. "Dude, trust me. As someone who's had a piece of both of THOSE, " - he pointed ahead at the two mares in front of them, Spike’s eyes immediately locking in on their swaying rears and they walked - "you are in for one Tartarus of a birthday party..."

Spike gulped. 'What am I doing!? I've never even TOUCHED a naked mare before and now I'm expected to go all the way with TWO at the SAME TIME!?' He could feel his heart hammering in his chest, breath coming in short bursts as the group began to make their way up the stairs to the second floor. His nerves had no effect between his legs, however, his erection still twitching in his pants as it pointed like a compass towards the pair of females walking in front of him. The sister-in-laws were chatting about something, Cadance more animatedly than Twilight as she wrapped an arm around her waist and pulled her close. Twilight quickly separated herself from the Alicorn with a blush, Cadance laughing at her as they entered the private hall.

Spike had an epiphany as they passed the door to his room; what if this was all a dream? 'Yeah... maybe I'm still asleep. I'm sure I'll wake up soon...' His wish would not come true, but the dragon would have a rude awakening as, distracted in his own thoughts, he bumped into Twilight, who had stopped in front of the door to the master bedroom. The tent in his pants poked her right between the cheeks of her rear, rubbing the tapered tip of his dragonhood against the soft globes of her ass and causing the dragon to groan before he quickly pulled away in embarrassment. Both dragon and mare had matching blushes across their faces, neither one able to say anything as they avoided eye contact with the other.

Spike jumped when Shining patted him on the back, Twilight doing the same as he slapped her ass in passing. "C'mon you two, save it for when we're actually inside!"

Both Spike and Twilight found their blushes growing to historic levels of embarrassment, turning away from one another and rubbing the back of their necks. Cadance giggled at the pair and opened the door to Twilight's bedchambers, beckoning them inside with a wave of her hand. "Let's get ourselves comfortable, shall we?"

Spike found it amazing as he entered the bedchambers at how knowing something was about to go down completely changed the atmosphere of the room. A room he had been in a thousand times before without problem suddenly weighed down on him, eyes focused on the bed the group approached as if it were the gallows and he the criminal. He also found it amazing that, even with all the conflicting thoughts and a kind of morbid metaphor in his mind, his member was STILL fully erect. He looked down at the tepee that was his pants, a wet spot forming at the peak of the tent as his tool prepared itself for the job to come.

Cadance and Twilight were the first to reach the grand bed, Spike suddenly stopping in place as, without warning, Cadance lifted her dress up and over her head in one smooth motion and tossed the garment to the side with her magic. She was gorgeous; smooth curves running up and down her body and giving the mare a perfect female form. She had on a pair of lacy pink panties and a matching bra, the only two articles of clothing that hid the Alicorn's body from the wide eyes of the dragon. Even then they barely obscured anything, and Spike was taking full advantage of this fact as he drunk in the sight of the first nearly-nude mare he had ever seen in real life.

Spike stood paralyzed as Cadance turned towards him, bringing her hands behind her back to begin working on something between her shoulders. His eyes widened as he watched her lacy bra start to move, staring at the thin piece of cloth that was the only barrier hiding the Alicorn's voluptuous bosom from his gaze. He didn’t get to stare long as the soft click of something plastic coming undone, in actuality as loud as a pin drop but in the dragon’s ears sounding like a bomb going off, was followed up by the garment falling to the floor.

Spike jumped when Shining grabbed his chin and lifted it to close his unknowingly open mouth, though he continued staring straight at the mare’s chest like a deer caught in headlights. A large, round, pink set of headlights with a darker center circle that tightened the briefs around his crotch.

“Ahh… that’s better. Always is nice to let the ladies breathe every once and awhile, wouldn’t you say Twilight?”

Twilight’s only reply was a blush before she followed Cadance’s example, reaching behind her and unclasping her bra. Though not as large as her sister-in-law's, her pair was no less impressive to Spike, who reached down and covered his crotch with his hands in order to hide his growing erection. Twilight made a similar move, crossing her arms over her bosom to hide her twin mounds from the world. At least until Cadance reached over and stopped her, giving her a calming smile that broke Twilight’s embarrassment and left her fully exposed to the two males in the room as she lowered her arms to her sides.

Shining gave his sister a whistle. “Lookin’ good, Twilight!” Cadance frowned at him, puffing her chest out to get his attention. He gave her a jokingly muttered “you too, hon,” as he passed her on his way to the bed, climbing on top of the sheets and laying on his back as he waited for somepony to join him.

Cadance playfully rolled her eyes at her husband, walking behind Twilight and wrapping her arms around her slim waist. “How about we get started, huh?” She gave her a light push on the ass to get her moving, the bookish mare stumbling forward onto the bed in front of her brother. Shining simply smiled at her and patted the bed next to him, Twilight following his unspoken invitation as she climbed up towards him.

As Twilight got situated, Cadance turned towards the unmoving dragon still standing by the doorway. She beckoned him to approach with a finger and half lidded eyes, the dragon still covering his crotch as he complied. When he got close enough Cadance placed her hands on his and pried them away from the impressive bulge between his legs. She reached down, Spike tensing up as he waited for the imminent contact to his groin, but instead the mare hooked her fingers underneath his shirt and began tugging it up.

“Let’s get the birthday boy nice and cozy, shall we?”

Spike lifted his arms and allowed the mare to undress him, blushing as she whistled at his physique. “My, you certainly are in good shape Spike.” He shivered when she ran her hands over his trim abs, working her soft hands over the light green scales that ran down his body. "You work out a lot?"

Spike shook his head. "N-no, not really. Just small jobs around town and helping Twilight with stuff in the castle..."

Cadance brought her hands back up, wrapping her arms around his shoulders in a light hug. She gave him a warm smile before leaning in and kissing him on the cheek, a strange sense of deja-vu hitting Spike as she pulled away. "It's okay, Spike. Lighten up a little. We're just here to have a little birthday fun."

He shut his eyes and sighed as Cadance unwrapped one of her hands from behind his back and snaked it down his front, quickly descending towards his waist. He opened his eyes and looked straight into hers, taking one last deep breath before giving her a nod of his head. She nodded back and smiled, looking down between the two of them as her fingers dug underneath the waistband of his pants.

"Let's see what we're working with here..."

Spike closed his eyes as the Alicorn crouched down in front of him. He couldn't watch! 'Crap, she's probably gonna see it and laugh at me. She's probably used to someone as big as Shining, and he's probably hung like a horse!' Spike gave himself a face-palm in his mind. 'I mean, he IS a horse! Why is that even a saying-' His eyes popped open as a rush of cool air washed over his draconic spear, staring straight ahead and standing as still as a statue as only silence followed his member's daring escape from the cloth prison that was his pants and briefs.

"Sweet Celestia..."

Spike gasped and glanced down as he felt another pony’s skin wrap against his shaft for the first time in his life. Cadance was on her knees, putting her face at the same level as his crotch. The mare held his pride up with both hands, eyes wide and mouth open as she gazed upon the foreign member before her. "Spike..."

The tantalizing tower of dragon dick was breathtakingly beautiful. The entire draconic spear practically shined in the light on its own, from the tapered tip designed to wedge easily into any tunnel it wished to plunder all the way down the pink rod of flesh to the base. Other than at the head, where a small bump signified a pleasing increase in girth for whoever attempted to take what the dragon was packing, the whole member was without a single imperfection; a perfect cylinder of pleasure waiting for somepony to play with.

Cadance’s breath hitched in her throat as she gawked at Spike’s impressive member, holding it as if was was some revered relic from ancient Equestria. She brought her other hand up and cupped the dragon’s warm balls, panting as she felt the twin orbs fill her hand with ease. The Alicorn could barely manage to hold one of the impressive globes in the palm of her hand, having to bring her other hand down to get a good grip on the dragon’s perfectly symmetrical light-green eggs. She lifted them, testing their weight as she rolled them around in their sac. With a blush she realized that she was now a member of a probably small group of mares throughout the entire history of Equestria who had the chance to fondle a dragon’s ‘jewels’, and probably the only one who was going to drain them of their life-bringing essence.

An intense heat in her loins almost made the Alicorn dive in right then and there and milk the dragon for all he was worth, but she held herself back and continued with the original plan. “Wow, Spike… this is-”

The twitching rod was suddenly pulled from her grasp as Spike stumbled away, pants still clinging onto him halfway off as he reached down to once again cover himself up. "It's too small, isn't it? I'm never going to please a mare with... with THIS!"

Cadance was flabbergasted. "Uh… buh… huh!?" She stood up and quickly made her way over to the dragon, reassuringly placing a hand on his shoulder and pulling away his hands with the other. "Spike, if there is one thing you are, it is CERTAINLY not too small... Celestia, I think you have an inch or two over Shining!" She once again grabbed onto his member, slowly stroking it up and down as she tried to build up his ego. "Spike, trust me when I say this; any mare would be lucky to have somepony like you. And I'm not even talking about having, well, " - she brought her other hand down and wrapped it just underneath the tapered head of his shaft - "THIS. You're one of the kindest, gentlest creatures I have ever met, pony or no." She gave him a smirk when he moaned from her continued ministrations, her hands expertly working over the contours of dragon flesh sticking out from between his thighs. "Plus, it's more about how you use it than the size. Though, this is certainly a nice bonus." Her hands left his erect rod to throb in the air on its own as the mare backed away and turned towards the bed. "And that's why we're here to teach you. Come this way, Spike."

Spike blushed and followed the mare towards the bed, using one hand to hold up his pants that threatened to trip him with each step he took. Once Cadance reached the bed she turned to talk to him, but she paused before speaking a single word when she noticed him hobbling his way over to her. She chuckled at him, pointing towards his pants as his blush grew even brighter from her laughter. "You can go ahead and take those off, Spike. We won't be needing them from here on out."

Spike sheepishly rubbed the back of his head and gave her a weak smile. "Oh... OK."

Letting go caused the pants to drop to the floor, pooling around his ankles in a puddle of cloth. He nearly tripped over himself as he stepped out of them, his entire body practically vibrating from excitement. He felt like he finally realized what was about to happen; he was gonna get laid, and with a Princess to boot! With newfound confidence he strode over to the bed, intent on sweeping Cadance off her hooves and pleasing her to the best of his abilities. At least, that was until she patted the ground next to her, turning her head towards the approaching dragon and asking him to sit.

“For now, watch what Shining does with Twilight. Make sure to pay attention to Twi’s reactions, and what he does to get those reactions from her.” She gave him a sly wink. “I’ll be expecting you to get the same from me…”

Spike tried to gulp down the lump in his throat. With a grunt he sat on the floor, crossing his legs in front of him with his pink pride peeking up between his thighs. He looked towards the mare seated next to him, eyes locking in on the curve of her breast that sat just a couple feet away from him. His mouth watered at the perked up stub on top of the mound, feeling a sudden urge to lean over and grab and knead the flesh between his fingers. Cadance apparently noticed his gaze, snapping her fingers in his line of sight to get his attention before, without a word, she pointed him in the direction of the bed.

What Spike saw brought a fresh wave of blood to both his cheeks and the member between his legs; Twilight was sitting on top of her brother's stomach, leaning down to kiss him right on the lips. From this angle Spike couldn't see much of what was happening up top, but he could certainly see what was happening below the stallion's waist.

Twilight had one of her hands between her legs, her dress-skirt lifted just enough to give Spike a glimpse of her purple panties as her fingers ran over a large wet spot at the frilly garment’s center. Her other hand was behind her and was openly groping the large bulge of Shining's crotch, fingers closing around the stallionhood hidden beneath his pants. Spike swore he could see the entire thing twitch as it was rubbed, feeling the ghost of Cadance’s hand from before rubbing his own. At least, he thought it was just his imagination up until Cadance went lower and cupped his balls, lightly rolling the heavy orbs around in her grasp.

"Now, Spike, it's always important to build up your partner. Don't just rush in and skip to the main event; foreplay can be some of the most pleasant parts of sex." She released the orbs from her grasp and let his balls rest once again on the floor, her hand moving up to wrap around the base of his tapered tip. "Of course, I'm sure by now you knew about that." Cadance turned towards the siblings on the bed and reached forward with her other hand to tap at her husband's leg. "Let's move on, hon. Can't see much with your clothes still on."

Shining groaned as he sat up with Twilight in his lap, her hand still cupping the tent of his pants. He made a move to remove his shirt but was stopped by his sister, who pulled his hands away and grabbed it with her own. "Let me, BBBFF..." She slowly pulled the cloth garment up and over his head, revealing a chest that appeared to be chiseled out of marble from years of guard training. Spike watched as his best friend began to grope her own brother, much like Cadance had done to him. At least until she brought her head down and began to make a trail of kisses down the center of his body, stopping only when she reached his waistline and the beginning of his pants.

She paused to rub her face against his prominent bulge, moaning from the warmth radiating from his crotch as she felt him twitch against her cheek. After one kiss to the tip of the obscured appendage she brought her hands up and grabbed onto the waistband of his pants. She looked up at her brother with half-lidded eyes and licked her lips. "Commando?"

Shining smirked at his sister, giving her a nod in reply. "You know me all too well, Twily..."

With a single pull Spike found out what Twilight was talking about; Shining's meaty shaft swinging out into the air as it was freed from his pants and tapping his sister on the nose. She gave him a quick kiss on the tip before continuing to pull his pants down, revealing a pair of black, plum-sized balls resting against his taint as she unveiled her brother’s most private parts to the world.

Spike glanced at Shining's stallionhood and his own, comparing the two in his mind. 'Huh... guess Cadance was right...' Even though Shining's was thicker, the tapered head of his own draconic shaft gave him about an inch over the stallion's more blunted flare. He shuddered as Cadance rubbed the sensitive head with her thumb, tracing small circles around it that shocked him with bursts of pleasure.

"Pay attention, Spike. This will be on your... 'test' later on." Cadance gave him a wink as color flooded his cheeks, knowing exactly what she was talking about. He gave her a weak nod before turning back to the pair of siblings on the bed. Twilight had-

Spike gasped.

Twilight had her lips wrapped around the tip of Shining's cock, her head bobbing up and down her brother's thick shaft. Shining had leaned back against the bed, interlocking his hands behind his head and sighing out in bliss as he let his sister have her way with him. And Celestia, was she ever! She would take just over half of his stallionhood into her gullet in one smooth motion, stopping just past the bulge of his medial ring to run her tongue over what had entered her mouth. As least that was what Spike assumed she did; lewd slurps and the sounds of wet flesh on flesh ringing around the room as Twilight gave her own brother a blowjob.

Cadance made sure to mimic Twilight’s actions as best as she could with her hand, attempting to prepare the dragon for what was to come after the ‘lesson’. She had one hand wrapped around the middle of his long shaft, lightly squeezing the hardened rod to simulate a mare’s mouth. The other was trailing her fingers around the head of his shaft, quick strokes with the tips of her digits that caused the dragon to shiver in her grasp. “Now then, how much do you know about marehoods?”

It took his mind a moment to register Cadance’s question as he watched Twilight start to push herself down to the base of the stallion's member. Spike's eyes grew with each inch of throbbing cock that disappeared into her mouth, a bulge clearly seen moving down her throat as Shining’s member pushed deeper and deeper into her. He released the breath he hadn’t realized he had been holding in as Twilight’s nose pressed into the white fur of her brother’s crotch, the dragon’s light moan masked by the much louder one each of the siblings made.

"Whoa..."

Without thought Spike found himself slowly approaching the pair of ponies on the bed, moving in to get a better look at the action. Twilight began to pull away from her brother’s lap, each inch of stallion cock escaping from her throat glistening in the light from her coating of saliva. Spike could feel a strange tugging sensation on his own dragon dick, imagining himself in Shining’s spot for a moment with Twilight gargling on his own lengthy tool before looking down between his legs.

Cadance was looking at him with an eyebrow raised, hand still wrapped around his cock as she pointed at the spot next to her with the other. “Be patient, Spike. Your turn will come soon enough.”

Spike grumbled as he retook his seat, muttering under his breath, “Jeez, it’s MY birthday…” Cadance rolled her eyes and continued stroking his cock, the dragon’s disappointment quickly fading as pleasure once more invaded his mind.

The Alicorn tapped her husband on the leg once again, giving him the signal to move on to something new. This time, Shining brought a hand down to Twilight’s face and rubbed her cheek as she finished pulling his cock from her mouth and gave her a wink. With one last kiss on the tip she stood, walking forward a few steps to stand above her still prone brother before turning away from him. With a blush she looked at Spike, giving him a weak smile as she began to remove her soaked panties.

Spike thought about the situation he was in. Here he was, watching the mare he practically thought of as his mother standing above her own brother as she slowly stripped herself of the only thin piece of cloth she wore. Heck, it was only like half-an-hour ago that the dragon was worried about the fact that SHE was worried, and now here he was about to watch her get down and dirty with her own flesh and blood.

For some reason, his cock gave a mighty throb at the thought...

He gave Twilight a slight nod and a weak smile, the mare returning it with a grin of her own before she let the damp garment fall from between her legs. Everything was revealed; plump purple pony pussy lips slightly inflamed from arousal, a strand of the mare’s excitement holding onto her panties before breaking off as the underwear fell away. She took a moment to lift one of her legs and removed the undergarment from herself completely, the purple panty tossed to the corner by her magic. Twilight blushed but kept her hands at her sides, letting Spike take in the sights of her nude body. And what a sight it was; Spike could feel himself throb in need as he traced the mare’s curves, pausing at her breasts to take them in before moving back down to the slit between her legs.

Once again his pride throbbed, though this time the reason was plain to see. Twilight was friggin hot!

‘There’s something I never expected to think today…’

With a wink towards her number one assistant Twilight began crouching down, lowering her hind end towards her brother’s face while bringing her’s closer to Shining’s crotch. Her methodical trip down was abruptly hastened as Shining’s arms wrapped around her waist and forcefully pulled her down right onto him. Both the mare’s and the dragon’s eyes widened as Shining immediately set to work on his sister’s juicy folds, long, deep licks diving into her slick tunnel to scoop out her sweet-tasting ambrosia. Just as it had when Twilight gave him a blowjob, lewd slurps and schlips began to come from the point of contact between brother and sister, this time sounding even sloppier as Twilight’s mare nectar was drunk straight from the tap to satiate the stallion’s thirst.

Twilight sat up straight on top of her brother, head leaning back to point at the ceiling as she gave a long, low moan to the heavens. She began to rub herself, hands working over her sides before moving up to cup her own breasts. Spike was mesmerized as the mare openly groped herself, kneading the dough-like globes of her breasts and causing them to jostle and jiggle about in her hands. She even took a moment to tweak the dark purple stubs of her nipples, moaning as she roughly fondled herself. Eventually her hands began heading southward, rubbing her sides and her stomach before reaching between her legs to spread herself apart and give her brother better access to her depths.

With her thick folds parted, Spike was given a direct line-of-sight to the bright pink flesh of Twilight’s marehood. Every so often her brother’s tongue would flick across the juicy folds to lick up her secretions, vibrations from the stallion’s groans running up his mouth into her quivering tunnel and causing the mare to moan. Spike could feel his dragonhood twitch and throb each time Twilight’s bulbous clit would wink out towards him, bright pink flashing from her thick purple lips as her body called out to be bred. Spike’s tongue extended from his mouth as he began to absentmindedly lick the air, mimicking the actions of the stallion buried underneath the mare’s plot who, from the sounds of things, was an expert at pleasing a mare.

Twilight cooed at her brother, lowering herself to lay flat on her belly on top of him. Her face wound up only inches from the stallion’s crotch and the mare nuzzled her cheek into the warmth radiating from the thick, black shaft. “Oh, Shiny… it’s been WAY too long since we did this…” Her wings extended, lifting up towards her head and Shining’s crotch. She wrapped the soft, feathery tips of her wings around the Prince’s thick shaft, rubbing it up and down as she laid a kiss on the flared head. Spike moaned to himself as Twilight rubbed her face across the top of Shining’s member, so focused on the pair of siblings on the bed that he never noticed Cadance palming the head of his own cock in her hand.

Twilight now had Shining’s cock encased by both her wings, her silky-smooth feathers pumping up and down as she suckled his head in her mouth and fondled his balls with her hands. Every so often she would pop the widening flare out of her mouth and rub her face against it, moaning and groaning as she smeared white streaks of stallion pre into her purple fur.

Cadance suddenly got up and tapped Twilight’s leg, lightly tugging on her tail to get the mare’s attention. “Shining’s close… we should move on before he finishes.”

The mare in question seemed to either not hear her, or she simply just didn’t care. Her wings were like a blur against his engorged cock, strands of pre sticking to her feathers and coating the stallion’s shaft with his own personal lubricant. Twilight cut the supply of lube off at the source, dragging her tongue across the face of Shining’s sensitive flare to lap up the drops of precum before they could even start to drip. Cadance got her attention with a firm slap on her rear, Twilight’s head abruptly pulling away from Shining’s lap as she gasped in shock. She looked behind at her sister-in-law, pouting even as her wings continued to rub her brother’s member. “What the hay was that for!?”

“I think it’s time to move on, Shining’s getting close. Remember why you invited us here.”

Twilight continued to jack her brother off with her wings, but, with a nod of her head towards her sister-in-law, began to gradually slow down. She rubbed his twitching shaft until she felt the bloated balls held in her hands try to pull up closer to his body, quickly ending all contact with Shining before he orgasmed. Shining gave a weary groan at being denied climax after getting so close, but his disappointment was short-lived as Twilight turned around and crawled up the bed on her hands and knees until she was parallel to him. Her tail lifted up over her back and out of the way of her marehood, showing off the plump, glistening lips to everypony in the room.

Shining excitedly stood up on the bed and made his way behind his sister, but before he could begin Cadance grabbed onto his shoulder and held him back. She held up a finger, signaling him to pause for a moment before she looked behind her at Spike. The dragon hadn’t moved from his spot on the floor and Cadance thought she could see a line of drool escape from his open mouth as he stared at the group of ponies on the bed. She waved her hand at him in an attempt to break his trance-like state.

“Come on up Spike, get closer for a better view…”

Judging by the glaze over his eyes, her bid to return Spike to the land of Equestria hadn’t worked. Still, the dragon subconsciously answered her call and made his way onto the bed to join her. As he got close, Cadance traced his line of sight down between Twilight’s legs.

The Princess of Love smirked to herself. ‘So, little Spikey-wikey likes what he sees…’

Cadance reached up and dragged two fingers between the plump folds of Twilight’s marehood, earning a heated moan from the mare before pulling back and revealing a strand of liquid connecting her digits. She brought it up to Spike, the dragon’s eyes slowly widening as the scent of a mare filled his nostrils. He shook his head to clear it of the mist that had settled over it before he looked down at Cadance’s hand.

“Nice to see you join us, Spike!”

He blushed and rubbed the back of his head. “Hehe… uh... sorry about that. It’s a little much to take in all at once…”

Cadance nodded her head. “I understand, Spike. The first time for anypony is usually overwhelming, and I wouldn’t exactly call this a normal first time.”

Spike glanced at the entwined siblings. Shining had one of his hands on Twilight’s face, using it to turn her head towards him as they shared a deep kiss. “Yeah… I’m pretty sure none of my friends’ firsts were like this…”

Cadance giggled and rubbed his shoulder. “You can say that again!”

Spike returned the chuckle, the light laughter breaking the oppressive atmosphere in the room that had weighed the dragon down ever since entering the room. Cadance gave him a warm smile as she watched his entire body relax. “Good to see you’re warming up to this. Sex should never be a serious thing; it’s all about having a good time!” She nodded her head towards the other ponies on the bed, smirking at the dragon who smiled back. “Now then, let’s get on with the lesson, shall we? We’re just about wrapped up here.” She dragged a fingertip across Spike’s dragonhood, still standing strong between his legs. “And then, it’s your turn, birthday boy…”

She turned to her husband, only having to give him a quick nod before he went to get into position. As Cadance and Spike laid on their bellies behind him, Shining knelt down on his knees behind Twilight. Spike had a front row seat as he grabbed his cock and sandwiched it between his sister’s leaking labial lips. Without penetrating her he thrust forward, hot-dogging his cock between her thick pussy lips and coating the long black rod in his sister’s own personal lubricant. From this angle Spike got a real good look of the size of Shining’s ‘spear’; it had to be over a foot long by at least a couple inches, with a meaty girth to boot. The dragon winced as he looked at Twilight’s entrance; how in Equestria they were going to manage to squeeze such a large pole into such a tight tunnel was beyond Spike.

“How exactly is this supposed to be pleasurable? It looks like he’s going to split her in half!”

Twilight moaned out. “Ohh… I sure hope so…”

Cadance tapped her husband’s waist a few times, a secret signal passed between husband and wife before she turned her attention to the questioning dragon. “Rather than tell you, it might be better if you’re just shown…”

Shining Armor pulled his hips back and lined himself up with Twilight’s slick passageway, the wide head of his stallionhood resting at the gates of her marehood before popping in with a light push against it. Spike’s eyes widened as the stallion slowly buried himself inside of Twilight’s clenching pussy, the lips of her marehood pulled tight around the girth of his member. He continued without pause, both siblings gasping when his medial ring passed through and moaning when he reached the base, balls lightly swinging forward to tap her rapidly winking clit. Then the process repeated, but in reverse. Spike didn’t think his eyes could go any wider as the shaft pulled out of Twilight, slick from the copious amounts of juices that dripped from her lips and shining in the light as Shining withdrew.

Cadance grabbed onto the base of her husband’s member at the end of his withdrawal, only the flared head sitting within Twilight’s warm tunnel. She absentmindedly rubbed him as she began to once again point things out to Spike. “This is why foreplay is so important. Building your partner up gets them nice and wet for your entry to be a smooth one.” She used her other hand to push on Shining’s rear, getting her husband to stand up a little so Spike could see. The movement had the unintended side effect of stirring up Twilight’s insides as Shining’s flare shifted, causing the mare to moan loudly into the pillow her head rested on. Another tap was all the signal the stallion needed to start up again, taking a moment to readjust himself while keeping himself at a higher angle so the audience behind him could see the action.

With a loud slap Shining buried himself once more into his sister, both ponies moaning out as a foot of pony cock plunged into Twilight’s marehood. Spike tried to take in every detail that he could; how far Shining would pull out, how fast he would push back in, and the adjustments the stallion made to hit different areas inside of Twilight. Wet squelching noises rang in his ears as Shining’s thick pride wedged open Twilight’s tight tunnel, drips of her excitement rolling down his shaft and balls before falling to the bed below.

Cadance tapped the awestruck dragon on the shoulder and led him over to the side of the bed, Spike moving without taking his eyes off the scene before him. His cock bobbed in the air as he crawled across the bed, nerves lighting up in pleasure as his shaft and large balls rubbed against his thigh. On this side of the bed he was perpendicular to the pair of rutting ponies, and he could see more of the siblings’ bodies as both of their faces twisted in pleasure. Shining had his eyes closed in concentration, focused on thrusting into his sister as hard and as fast as he could. Twilight’s were opened, but Spike doubted that she actually saw anything from the way she blankly stared at the wall in front of her. Her eyes were rolled up as far as they could go, her mouth open and tongue lolling out of her mouth as she gasped and moaned with each smacking thrust her brother made against her rear. Spike watched as her curves jiggled from the force, her breasts especially as the two mounds swung wildly beneath her.

Shining curled in closer to Twilight’s body and began jackhammering the last couple of inches of his stallionhood in and out of her at ludicrous speeds. Twilight gasped and lowered her head, reaching between her legs to rub at her clit with two fingers as the stallion pounded her as hard as he could. Spike’s shaft gave a mighty throb as he watched their reactions, imagining himself inside of Twilight as he hammered his draconic pride into her warm depths. He imagined her moaning his name as she clenched around him, calling out the name of the dragon who brought her such pleasure. The feeling of Cadance’s hand wrapping around his member returned, and without even taking a glance between his legs he began to lightly thrust against her as he did to the Twilight in his mind.

Twilight was gasping with each bed-creaking thrust from her brother, a slick combination of her juices and his running down the side of her leg to form a puddle on the bed. Taking a peek down her body gave her the view of Shining’s globular balls swinging forth to smack into her clit, a bolt of pleasure striking her center each time the wet thwap rang in her ears. The force of his thrusts forced her face into the pillow below, and as she turned her head and moaned Shining’s name she saw Spike and Cadance sitting on the bed next to her. Her tunnel spasmed and clenched around the stallionhood within her as she got her first good look at Spike’s shaft, the pink hand of her sister-in-law running up and down the long spire of draconic dick.

Imagining Spike laying underneath her, joining Shining inside of her marehood as the two males roughly bred her deep into the night was the last straw, the last thought she made before her world was reduced to static. She heard a mare screaming in the distance, the voice registering in her head as her own though she could not feel herself making noise. All she felt was her tunnel clenching around the hard rod of stallion steel still thrusting in and out of her, the added lubricant of her orgasm helping the shaft reach deep enough to kiss her cervix with ease.

Spike gasped when he heard Twilight, peeking between her legs to watch as her clit furiously winked in and out of her marehood. Jets of marecum rocketed out of her lips to paint her brother’s balls and thighs with her sweet nectar of bliss. Without pause Shining continued his deep thrusts, Twilight’s scream being reduced to incoherent babbles as waves of pleasure constantly crashed against her shores.

Spike watched mesmerized as rivulets of marecum ran down Shining’s rigid shaft. It seemed like the stallion would never stop sawing the last couple inches of his shaft in and out of the quivering mare beneath him. Only when Twilight collapsed onto the bed did Shining change up his thrusts, and even then it was only to use more of his member with each thrust, almost the entirety of his shaft tugging on her insides as it evacuated her tunnel before shoving itself back inside all the way to the base.

Twilight picked her head up from the puddle of drool she had made, gasping out as Shining started picking up the pace once again. The heights of pleasure she had just started to climb down from once more rushed into her loins, tongue lolling out as she rocked her body back and forth with her brother’s thrusts.

“OH! Shining! Fuck me! Harder, harder! Ooohhh…”

Spike’s member throbbed in Cadance’s grip as another salvo of marecum gushed out of Twilight’s battered marehood. This time, Shining continued thrusting the entirety of his shaft in and out of the squirting lips, lewd squelches and wet thumps ringing in the room as the stallion expertly pleased his sister through a second straight orgasm. Just as her climax began to die down Shining suddenly buried himself to the hilt and held himself there, groaning as his balls twitched and unleashed a heavy salvo of stallion seed deep into his sister.

Twilight’s mouth opened in a silent scream. The first shot of warmth into her depths caused her to fall head first into another round of spasms, the third orgasm of the night causing her eyes to roll into the back of her head and her tongue to loll out of her mouth. After the first barrage of shots, Shining began to thrust once again. He timed each thrust with the surges of semen spewing from his stallionhood, pulling out after each shot only to bury himself to the hilt before the next.

Spike’s eyes widened as Shining’s orgasm dragged on further than he thought possible. They widened even more as he saw Twilight’s stomach start to slightly balloon outwards, the immense load her brother was pumping into her bloating out her belly with stallion semen. Eventually, the pressure became too much, thick lines of pressurized cream leaking around Shining’s thick cock to rocket out against his balls. By the time his orgasm began to die down, most of the fur around his crotch was matted with a mixture of his and her cum.

Shining sighed, wrapping his arm around Twilight’s midsection as he leaned down and kissed her on the cheek. The mare’s only response was a weak twitch, drooling on the pillow her face was pressed into. Shining smiled at her as he straightened up, patting her on the ass before beginning to pull out his spent shaft from her weary passage. Each inch of fat stallion cock was followed by another stream of cum gushing out to puddle on the bed, until, at last, the wide flare escaped the confines of Twilight’s marehood with a loud pop.

Spike stood with his mouth open as white cream gushed from the mare’s gaping tunnel. It took a few moments for Twilight’s lips to return to their normal shape, and even then a small stream leaked from her lips and coated her thighs. He jumped when Cadance grabbed his shoulder, the mare grinning at him with eyes half-lidded as she continued to rub his aching erection.

“Looks like it’s your turn, Spikey-wikey… I sure hope you've been paying attention...”

Spike nervously gulped.

'Uh-oh...'
