Chapter 3: The Family That Plays Together, Stays Together

Previous Chapter

Turns out three years made all the difference. Twilight assumed she buried a mistake in her past. A single moment of weakness when her emotions got the better of her. Coincidentally, with running off to Ponyville and Shining joining the military, she was afforded the chance to leave these confusing feelings behind. And for the longest time she hadn’t thought about it. But the moment her brother came back into her life: heart fluttered, throat tightened, and she felt a little queasy. Maybe time apart made it worse. Too much anticipation was self-destructive after all.

What’s wrong with me? She demanded, concerned she might have contracted some sort of disease. The pain coming as a slow clenching. And, she thought it odd she was saying this, but it literally felt like a knot had formed in her stomach.

“So you knew?” Twilight’s voice cracked, barely managing to finish out the question. Eyes searching her parents' faces, as if confirming what her mother said could make the sickness subside. Illness a symptom of confusion a misunderstanding. It did not. Another part of her secretly acknowledging the truth her mind would not accept. Growing wet and impatient in the gap between her thighs. Sabotaging her will.

“Really Twilight, you should give us some credit as parents. It would be awful if our own children were having sex and we didn’t even know,” Velvet said, joining her husband in the kitchen. She nibbled playfully at Night-light’s ear, pushing up against the kitchen counter, banging on a cabinet door that refused to get out of their way. He bit back, sucking her neck. She rolled her head to the side, granting him better access to nuzzle her satin skin.

Twilight, trying to retain some modesty, looked away. Though not at Shining. She couldn’t manage that yet. The memory of being taken by him rose once again and her symptoms flared. Those thoughts didn’t belong. They were making her ill, causing uncertainty to cloud her judgment. Basic need for his affection was illogical. There were other stallions that could satisfy her bestial desires. And if that couldn’t be arranged she knew- certain spells. Aware of society’s rules; what the other ponies would think. Just because her family legacy of such debauchery didn’t excuse her actions. Sex with her brother was a mistake, that was all. But if that were the case, then how come the only thing she could think about was getting a chance to do it again?

“The main thing is we’re not mad Twilight. In fact, it’s quite the opposite,” Night-light assured as Velvet continued to poke and prod, causing him to dribble some tea down his front, “It’s okay to show the ones you love just how much they mean to you. Sex can be many things, but for somepony special, it is the physical manifestation of that love.”

Twilight Velvet stole the last of his words planting a sensuous kiss across his lips, ending with a playful tug using her teeth. Nigh-light set down his tea. “What your father’s trying to say is love's complicated. It’s something you have to decide for yourself. And, when you’re ready, share it.” Velvet giggled at her daughter’s continued silence, “Looks like we should provide an example.”

Taking more than a quick peck this time Velvet dove in, mashing her snout into her husband’s. Drawing his tongue into the vacuum between their mouths, they struggled to taste one another, saliva sealing the conjoining orifices. Night-light returned the gesture by illuminating his horn and focusing a simple psionic upon her fur. The hair stood static under the glow as Velvet felt several intrusive magical fields ravaging her curves. Each once acted independent, squeezing or rubbing or pushing at her body. Her breasts pushed together, compacted to the point where it felt like there was no more room between them, and then released. The motion repeated over and over she bucked lightly. Delighted in part due to the precision of the spell which provided equally distributed amounts of pressure across her form. One magic field proceeded to fold itself, slipping between her plump mounds, and then expanded all at once opening her sopping pussy with a ‘pop.’ At the intrusion she gasped, then retaliated, enveloping her husband’s most sensitive spot in her own magical aura. Tugging the dangling pouch until its contents erected, much to her excitement.

Stunned that her parents were heatedly fondling each other and quickly progressing toward full blown intercourse, Twilight did the one thing she was most practiced at: she sat and studied the situation. Shouldn’t she be revolted? Wasn’t there some societal influence to condemn this action? Not only were her parents literally going at one another unabashed, but they were siblings. Didn’t that matter?

No. It didn’t. Twilight shook her head, surprised at the confidence in her conclusion, but it was true. That moment, nothing else mattered to her parents. Strangely enchanting such a sensual sense expression could exist between two ponies. Each of their movements so refined it belied the hours of exploration it must have taken place to memorize exactly what each of them wanted from a sexual encounter.

Twilight realized the emotion welling up in her wasn’t disgust over what she had done in the past. It was jealousy. Envious she wasn’t able to experience the connection her parents had. Angry she wasn’t courageous enough to rebel at what society dictated. And depressed that maybe she had missed her chance to ever be with Shining again. All the time spent thinking about her brother and that night, wondering if she could come up with another excuse. Just to let him know that she wanted something more than a brother. That everything they had done was okay because it felt so right. Perhaps a wasted effort.

Velvet and Night-light continued to wrestle across the kitchen tile. Mother mare playfully took a long, lavishing lick at Father’s behind. Cleaning the area from taint to tail, spit enticed the crevasse to arousal. Visibly, Night-light shivered, the wet skin exposed to air, made sensitive to even the slightest breeze. Large hanging spheres swung pendulously between his legs as his scrotum acclimated to its new saliva coating. Spit dripping down, prepping for the inevitable debauchery. Intrigued by Velvet’s friskiness, he indulged a sniff at her backside, judging how his efforts were coming along. Apparently, he was doing very nicely because a musky odor permeated from between her cresting flanks. Arousal rolled into his sinuses and devoted his mind completely to pleasuring her. So the magical massage continued to pound her body, unrelenting. Side by side now, his mare plucking hungrily at his distending shaft, Night-light planted his snout on her flank and took another deep, suffocating breath. Hairs from her rear tickled the inside of his nostrils as he kept nuzzling her fine lacquered coat. A quick flick of the tongue allowed him to taste her cutie mark: stars resonant of bitter earthen flavors, a hint of saccharine perhaps, this due to being a freshly showered mare. Twilight Velvet reeled at the attempt on her rear, sputtering loudly in a combination of grunts and moans. Purple and white tail flicked back to fend him away, but only managed to entice his lust further; wafting her scent around the room. Fruitless in her efforts, she decided the only appropriate course of action would be to perpetrate her own erogenous attack. Deftly cupping her husband’s scrotum with her fore-hooves, Velvet allowed her pursed lips to draw some of the forgotten smegma from around the base of his loins. Proceeding, she bisected his testis with a probing tongue eventually sucking one of them into her maw for a taste. She swirled it around relishing the textures and flavors of its package before allowing it to fall back to its standby position. Over the years she had been allowed to become intimately acquainted with such a delicate part of her husband. Far be it for a male to show any kind of weakness. Every suck, nibble, pinch and prod carefully placed to ensure pleasure, not pain.


Shining watched his little sister continue to squirm at the sight of their parents. An enlightening experience, if not mentally scarring. The deliberate fondness of each action as lovers crisscrossed, searching out their favorite spots. Breaking away from the spectacle for a moment, he considered Twilight. It was curious. She grown more beautiful in their time apart, maturing in the areas he had hoped, but it wasn’t really the reason he felt attracted to her. Well, to be fair, his throbbing sex was appreciative of her looks, but it was mainly the familiarity of her body. The fact that he was comfortable thinking about her as his pride swelled beneath him. Like there was something just right about mounting her supple frame and whispering that he would take care of her into her ear. The only mare who knew him better was probably his own mother. And considering how much he loved her…

“Twilight.”

Ever the big brother, Shining could see the timidness in her eyes as she watched the contorting ponies on the ground. Studious as always, thought Shining.

“Twiley,” Shining repeated.

No response.


By now Twilight Velvet and Night-light were on act two of their performance: the presentation. The playful mare straddled her husband’s chest, laying pouty pony pussy out on display. Its sopping heat left a trail of need stuck to him as her puffy lips winked, pleading for attention. Night-light lifted his head to the paunch, simultaneously stimulating her anus with a wet nose. The flesh gave way initially. Cheeks spreading, until Velvet shuttered, her muscles contracting around the familiar phallic shape of his snout, inviting him to remain lodged in her pale, finely toned ass. Incensed by female aroma, Night-light licked the sopping passage, spreading her labia wide and stimulating her clit. Also his nose buried itself deeper into her perfect little doughnut anus, satisfying the needs of both her holes. In shock more of Velvet’s essence trickled out. A reward for his diligence.

Obviously enjoying herself, but not wanting to be outdone, Velvet looked down at the full girth of her mate’s heaving rod. The member jiggled up and down cutely as Night-light worked, feverishly eating out her behind. Inviting as it was, she bypassed it, favoring something a bit more teasing.

“Yeeeiy!” Night-light yelped, breaking the typical sexual oratory by letting out a rather un-manly squeal. Velvet’s tongue now lapped his own puckered plot-hole, readying it for a spell. The attention, while not what he was accustomed to, wasn’t necessarily unwanted. Gradually Night-light relaxed, but felt a pressure building at the budded entrance. Velvet solidified a magical field; the presence penetrating a few centimeters into his anal passage. Night-light emitted a solitary grunt over the sensation. As his sphincter clenched and unclenched, the aura slid further and further in, filling up the hole. The pressure on his prostate drove his already formidable penis to new lengths as it stiffened further, determined to satisfy his frisky lover. He bucked softly up at her, practically begging for any sort of resistance against the pulsating phallus. Confirming his groans of pleasure, Velvet relented, returning her attention to his demanding sex. However, again she did not immediately satisfy its wish, sadistically noting her methods must be driving him crazy since his lapping at her genitals ceased. She also took a moment to dispel the force rooting around inside of his ass. All his attention was to be focused on this moment. That way its impact would be greater. Carefully, she lowered her snout to his stallionhood making sure not to contact it and exhaled, caressing it with a cloud of moist pony-temperature heat. Night-light shook uncontrollably, disgruntled that she had barely touched him yet elicited such manic need.

He voiced concern, barely above a whisper, “C’mon honey. That’s not fair…”

“Fine, spoilsport,” she mocked, “I’ll have a taste.”

Starting at the tip she slowly, painstakingly, enveloped his flare in her cheeks. Having them puff out around its circumference. Coyly, she offered her tongue at his urethra, relishing a dribble of pre-cum that surfaced there. No wonder they named her Velvet. She was a goddess with her tongue and it was as soft as her namesake. The long appendage skillfully wrapped around his dick and took a single pump all the way to the base. Velvet watching her stallion’s scrotum pulse as she ascended back up the shaft, pausing again at its head for a loud slurp before popping her lips off it. The depressing of her lungs resulted in a sultry “ahhhh” as if she had just enjoyed a refreshing beverage. Her scintillating display made her children acknowledge she was indeed sexy, in every sense of the word.

Shining couldn’t stand waiting anymore. There would be no more mixed feelings or ‘could-haves.’ He needed to clear things up. “Sis, I think we should tal-”

Twilight Sparkle didn’t give him the chance. Immediately, Shining was tackled to the ground, purple pony using her full weight to overcome him. She dug her face into his broad chest, soft white hairs matted against her own plush violet coat. He coddled the younger mare in his hooves, strangely feeling his fur dampen. Tears poured from her eyes, the sobbing coming uncontrollably. Shining was surprised Twilight’s emotions finally managed to surface. He never could tell exactly what she was thinking. In some sense it was a relief. That means she must feel the same way.

“I-I’m so… it’s just that,” sniffled Twilight, unable to finish a thought as she attempted to cover her face. “I can’t, I just Shiny- I just, I want…”

The words wouldn’t come. Her intellect failed, leaving her powerless to fend off her feelings. Those same fears as when she was little crept into her mind producing a storm of doubt. What if he rejects me? If he doesn’t feel the same way as I do about him? Why do I feel like this in the first place? This is so wrong…

She squeezed her eyes tight trying to dam up the tears, continuing to utter nonsense. Seeing her resolve crumple, Shining decided it was his duty to take the initiative.

“Don’t,” he stated simply, “Some things don’t need to be understood. If they feel right, then there has to be something good about them, right?” Shining leaned rose his head to Twilight’s ear and whispered, “I love you sis.”


“Oh look hon, the kids are finally getting along,” Twilight Velvet remarked, taking a break from fornicating to see her offspring pawing at each other. She continued to invigorate her husband’s phallus, taking precise steps to escalate the procedure. Currently she was at the stage where she had ingested about half of its length, deep throating it quite nicely.
“Mmhm,” Night-light agreed, though he was unable to pay attention to anything other than his wife’s protrusive posterior. Its sights and smells re-stimulated his carnality, wanting again to pleasure her holes. Where to start was the question.

That delicious slobbering pussy? Her beckoning ringed anus? Or… Once more he found himself returning to his favorite spot: a cleft of flesh that stretched between tush and tail. The patch wasn’t covered in the soft fur of her coat or by the long silks of her tail. It was simply bare like her marehood. And even though she had washed earlier, it was one of those ‘hard to reach’ places, basted in a bit of yesterday’s juices. So the refined flavor of a mature female still waited in the creases of her loins. Tilting his head, Night-light aligned his snout for a suckling. Hearing his wife inhale sharply, he knew he hit the right spot.

“Oh my goodness Nighty-night… that’s amazing,” Velvet let the compliment slip as well as the pet name, thoroughly pleased that she had a mate so generous and willing. Truly, Shining still had a lot to learn.


He was doing his best though. Taking after their parents, the contorting forms of Twilight Sparkle and Shining Armor were expressing the pent-up desires that were three years coming. There wasn’t as much care in the process, just a sense of urgency. Their only purpose was to sate their growing lust. Furiously grappling each other, Twilight stopped crying to focus her attention on prepping for their inevitable mating. Atop him, her resulting movement was a desperate attempt to grind her marehood into his groin. However sloppily done, it did seem to work since Shining’s cock springing to life, intent on delivering its load into his sister proper.

“Oh Shiny, please. I-I need it. I want you to fill me up,” the purple pony begged.

Forcefully, Shining pushed his sister to the ground, trading places so that now he was on top. Looking up, she wrapped her fore-hooves behind him and pulled, closing in for a kiss before his genitals slid into her winking crotch. As the pair began to buck in excitement, Shining felt his sister hump back at him, following his rod out of her drenched marehood. The priority: getting the shaft back into her as quickly as possible. Juices spilled forth, congealing with spit and sweat, to create suction between two bodies. Pounding away, Twilight recognized the familiar sensation of her brother halting inside of her. His thrusts grew more erratic, betraying his intentions. He started to pull out, but Twilight kinetically stopped him with an aura of magic.

“No, it’s okay Shiny. I want it.”

They were the words he’d been waiting to hear. Shining surged forward at the invitation to seed his little sister. A few final strokes from her pulsating vaginal walls prompted the flood of semen. Heat pouring into her: giving her a warm, full feeling. It was like nothing she ever felt before. As if all the sex pervious to this encounter was just meaningless bucking. She found her true mate, a special somepony to share love with. Still caught up in the moment, Shining lowered his mouth around Twilight’s horn and gave it a powerful slurp.

Perhaps she had spoken too soon. This was like nothing she ever felt before. Twilight had no idea horns could work that way. Of course she knew they were sensitive, but to use it so deviantly… Her mind went blank, and for a moment all she could feel tingling at the base of her spine. Then a surge shuttered from her pelvis, erupting as a plume of opaque fluid which painted her brother’s invading phallus. She lurched up into her brother’s waiting embrace, panting. His member still sheathed inside her. The two hugged, each unwilling to let go, as tears returned to Twilight’s eyes.

“Thank you Big Brother. Thank you for sharing with me.”


Moving past foreplay, Velvet and Nigh-light were ready to proceed with full blown intercourse. They had done a fair job exiting each other for the main event. Her yawing vagina easily swallowed her husband’s rod with an un-ladylike squelch. Hopping up and down, the missus brought her vagina down the entire length of the shaft, slapping lightly against his balls, creaming the base and scrotum with cum. The full range of her movement was quite impressive, as she managed to lean over and nuzzle Night-light while still keeping pace. Building inside of her, his cock expanded to push out against the interior of her vagina. Its flare prompting a healthy amount of mare lubricant to escape. Feeling the cock’s growth peak inside her, Velvet quickly dismounted, much to her husband’s chagrin.

“Don’t worry dear,” she coaxed, obviously with a plan, “Let’s just try something new.”

Cradling the penis between her voluptuous breasts, Velvet began shifting again. Using magic to steady the motion Velvet’s tits bounced, letting him feel vibrations through her soft fat rather than the typical slap of mammaries on his stomach. Breasts continued to mash against his heaving erection until he couldn’t take it anymore. For the grand finale, Velvet spread her haunches across his lap, boobs bobbing to a halt. Leaning over, she enveloped the tip of her husband’s pride in one massive gulp, greedily slurping at it to draw out her prize. And come it did, hot sperm shooting everywhere, coating his wife in sticky secretions.

“Well that was a little hasty,” Velvet shot at Night-light, somewhat disappointed that her husband had climaxed without her. Though, it was a cruel expectation, as there was really no way resist her efforts. Laying in bliss, the collective of ponies exhaled. Father, Mother, Daughter, Son. Twilight personally felt a heavy weight lifting, the knot in her stomach untangling. So far she had only studied in friendship, but ‘love’ was perhaps a stronger emotion still.

Her mother turned to her, “So, do you want to switch?”

Twilight considered for a moment what her father would feel like. Different than Shining for sure. Passionate, with experience. For the most part what Twilight and Shiny did was experimenting.

Wow, I really must be a perverted pony, Twilight reconciled, dripping over the idea of her father, thinking about sex this much.

The floor of the kitchen now interspersed with pooling sex juices, accommodated the seeping kinkiness of the ponies. The room saturated with the smells of shame and lust.

“What? We could go all at once if you prefer…” Velvet said, insinuating that the two incestuous pairs combine to become an incestuous orgy. Her daughter intrigued by the proposition and obviously her son not having any objections.
Beckoning, Velvet slid off her mount and sidled over to hook a hoof around Shining. She prodded vainly at his retracting bulge. Shining struggled to overcome his physical limitations on willpower alone smelling the permeating arousal of his mother.

Fortunately, Night-light had plenty of experience with the refractory period. Being a male it was a frustrating problem, but being a unicorn, the solution was easy.

“Another round?” Night-light urged, “Guess we wouldn’t want to disappoint our ladies, would we?”

With that, his father focused, conjuring a magical blue aura beneath each of them. The cylindrical projections spurring their stallionhoods back to full size. The magic washed over their shafts bathing them with a thousand little pinpricks. To Shining it was similar to what it felt like when his leg fell asleep. Only this time it was his penis. The pleasure culminated, pressure building within his testicles. Semen loaded at the base of the barrel, ready to fire. Shining’s rod stiffed to the point where every pulse of blood thumped it against his belly in excitement. Devious smiles spread across their partner’s faces as the mares realized there would be more entertainment this evening.

Velvet wiggled atop her husband, healthy backside jiggling invitingly at Shining. Her son pounced upon it. Rubbing his chest against her arching back he brought himself up to her flushed rear, stabbing at the entrance. It was no less than what she deserved after all her teasing, as now she was the mare begging for it.

“Shining, I can’t wait- let me have it,” she groaned, backing into him so her marehood could slobber across the top of his penis. Now wet, it slipped between her thighs massaging her tulip-ed opening with a messy squelch.

Seeing her brother entrenched in her mother caused Twilight to succumb to a new level of depravity. It was a primal feeling, embarrassing for sompony who considered herself above the ‘base urges of animals.’ She could feel her ass waving back and forth, pleading to get pounded. Maybe it wasn’t so bad. After all, she had given in to her brother, who cares how much further she went now? In fact, it was sort of relaxing: letting go. Not taking the time to criticize every action. Only need and instinct drove her. She had lost control.

Night-light could see his daughter struggling. Evidenced by the strained look on her face. Judging by how things progressed so far, he concluded he and the Mrs. actually did a fairly good job acclimating her to their family situation. Also, watching and hearing the scene between Velvet and Shining put him back in the mood. Though he didn’t want to pressure Twilight into anything. His little filly already had such a big day.

The puddle on the floor spoke for her though. Shouted really, advertising a sensuous odor like a sample of the latest Canterlot perfume. Which compelled Night-light to respond: appearing next to her.

“Twilight,” he whispered “if it’s too much-”

“No dad, I want to. Really.”

She was still extremely sensitive from her earlier rutting, but at this point Twilight was willing to try anything. Which was good, because Night-light planned on making things a little more interesting.

“Over there,” he instructed as she turned to face her mother, “and get down.”

Twilight squeezed herself underneath Velvet, pushing her purple head past her mother’s swaying teats. Shining didn’t stop pounding away. Still ensnared in the heat of the moment, Twilight lapped up the residue left in the gap between mother and brother. Then looking back on her form, she saw Night-light draw close, sandwiching her and Velvet between the two stallions.

“Oh my gosh,” Twilight moaned, “this- mother I can’t believe… this is- just so impossible.”

“Well life is about more than just friendships dear.”

On either side, fluids and magic gushed from the orifices of the ponies. The mares attended to each other’s holes as well as their stallions' members. Involuntarily, as the ponies neared climax, magic flooded from their horns out across their mingling bodies, mashing them closer and closer together. That prickly feeling enrapturing each of them in turn. Never before had Twilight been as close to her family. Literally and physically. Her parents were right. She was lucky to be able to share this experience with those ponies she loved most. It would be complicated, but she could get used to this. Seizing up, mother and daughter released. Shining and Night-light feeling the shiver of vaginas stroke against their phalluses came as well. Sperm once again giving Twilight that warm safe feeling. Now being able to share with her father as much as she was her brother.

Twilight smiled. Completely satisfied she was able to continue the family tradition. Celestia was due for a letter, detailing the only love stronger than friendship: family.

“H-happy Mother’s Day.”
