Family Incestry

Twilight failed. She still hadn’t gotten the perfect present, let alone a present at all. Worse, she was already at her parent’s house.

I bet Shiny got mom something really nice she brooded, wondering how to compensate for her efforts. Maybe some flowers? Or a nice piece of jewelry? A book? No, too expected. None of those things conveyed her true feelings. Besides, it was too late to do anything now. Potential solutions would have to wait.

Chomping down her oatmeal Twilight greeted her father, Night-light Sparkle, returning from his errands. A fresh bouquet of roses perched in his mouth. Twilight was glad she hadn’t done that. Dad always gets Mom flowers, duh.

“Something wrong pumpkin?” Night-light offered. Parental intuition.

“Ugghh,” huffed Twilight, prepping the room for her complaints, “I was going to surprise Mom by making a lovely histogram of our family, only the research materials were no help at all. I was sure with all the information here in Canterlot there would be something, but no. Apparently documenting over three-thousand years of history is an excuse to forget about the most recent hundred or so. I mean really, anypony would have assumed their research started with the most recent decedents working back from there…”

Night-light nodded, half-heartedly acknowledging his daughter as she droned on. Slipping a teabag out of the cabinet and into a steaming mug of water, he relaxed. It was best to have a little distraction when Twilight was being Twilight.

Suddenly, she chuckled. Something atypical of her usual rants. “Actually, you should speak with one of the castle’s reference librarians. Did you know they forgot to list one of you with parents? There’s only one pair noted for the both of you. Kind of silly, right?”

Night-light averted his gaze and set down his tea. Careless, should have seen it coming. In fact, looking at Twilight, he saw it building: the coming torrent of questions. Such a dangerous animal when provoked by curiosity, undoubtedly she would probe too far. Further than he was comfortable with at least.

They were going to wait to tell her when she was older, right? About their relationship? Well, maybe she already was older. And she was going to find out sooner or later...

Life in Canterlot was hectic. Royal duties had consumed each of the Sparkles in turn; Shining a soldier, Twilight apprentice to Celestia, Velvet an ambassador, Night-light a council member. Leaving very little time to reflect on trivial things like ‘who begot whom.’ Truthfully, it had been years since the last time any of them saw hide or hair of their relatives.

Unsure how to approach the subject, Night-light began with an aside, “So Twilight, you know you and your brother are purebred unicorns, right?”

“Obviously, since you and Mom are both unicorns.”

“And we’re purebreds as well.”

“So grandpa and grandma are unicorns. Makes sense. Why’s that unusual?”

“Well,” Night-light continued, hoping to avoid further detail, “it’s because Crescent and Gleam Sparkle, your grandparents, come from a long line of purebreds.”

“Okay. Though I’m sure plenty of unicorn families go back generations.”

“Yes but, in order to keep their bloodlines pure, those families chose to follow royal Canterlot tradition. To breed more powerful unicorns.”

“A royal tradition?” Twilight interjected, trying to listen to her father but eager to hear whatever secret it was obvious he was hiding, “What royal tradition? And what’s that got to do with-“

Then it hit her. Once, she read about an old tradition enacted to promoted inter-marriage of family members to breed desirable traits into future generations of equines. Traits useful to the monarchy, like magical aptitude in unicorns.

No.

“Wait. Does that mean grandma and grandpa are-?”

“Yes,” Night-light admitted reluctantly. Realizing she had figured it out, he cut her off before she could say more.

She said it anyway. “Brother and sister?”

“Yes,” Night-light repeated. He hoped telling her was the right thing to do.

“S-so wait, are you and Mom…” The purple mare’s throat closed around her words.

Ah, there it was. What he had been truly afraid of. “Yeah, but sweetie-” It was no use.

The confession broke the dam, her feelings flew out unfettered. “Oh my- it can’t… NO! Sweet Celestia, no!”

Taking her mentor’s name in vain; it was serious. Hyperventilating, daughter fell into father’s embrace, a soothing stroke brushing the nape of her neck.

“It’s not that hard to imagine. You and your brother are both very gifted unicorns. Your mother always expected you would find out eventually.”

“But i-isn’t that- isn’t that… ” calming down, but still blubbering a little, she still couldn’t bring herself to say it. Incest. It made her feel funny. It made her think about Shining. And she knew why.

“Does that mean Grandma and Grandpa forced the two of you to-?”

“No,” Night-light laughed awkwardly. He had forgotten how cute she was when all worked up like this, “I love your mother dearly. Growing up together we realized how important we were to one another. It was actually a relief when we found out about your grandparents and they consented to let us marry.”

“Does Shining know about this?” Twilight continued to press her father.

“He’s known for a while now. We, well- uh…”

“We hesitated to tell you,” Twilight Velvet interrupted, followed closely by Shining Armor, “and I’m sure you can imagine why Twilight. It must be a lot of pressure being Celestia’s star pupil. Better not to get involved in the semantics of something beyond your control. You know how you are.”

“Basically, you didn’t think I could handle the truth?” Twilight jabbed, feeling more than slightly betrayed. Velvet and Night-light exchanged a knowing glance.

“No honey, of course not,” Night-light consoled her, “we always intended to tell you.”

“Actually dear,” Twilight Velvet chimed in, “I thought you’d be happy when you found out. You know, since you and Shiny-”

“Mother!” Twilight shouted, rather incriminatingly. Causing her to blush and look away from her brother.

True, Twilight Sparkle had always had a crush on her brother. How could she not? He loved playing games, exploring, teaching her new things; all activities she enjoyed too. In fact the first spell she ever learned, how to illuminate her horn, she learned from her brother. Not that she had ever been scared of the dark or anything like that. Besides, it was frightening to talk to the other foals her age, let alone colts. What if they didn’t like her? What if she got teased? Or, worse yet, what if they just ignored her? She wasn’t good at handling rejection. Probably because she never gave anypony the chance.

An irritable heat emanated underneath her tail, by now a familiar sensation. Like that first day she tried something with Shining. She recalled walking home from classes one day a few years back. Her brother and Cadence in tow.

“So Shiny,” Twilight overheard Cadence say, “I heard it was your parent’s anniversary tonight. Think it would be a good time for us to…” the alicorn trailed off, hoping he would fill in the details. To her disappointment he did.

“I can’t. I gotta take care of Twily tonight.”

“Mmmm, that’s okay. You’re a good brother,” she relented, flicking her tail against Shining’s posterior coyly. “We can always try something another time anyways. Have a good night Shiny,” Cadence said, almost at a whisper, drawing her boyfriend in closer.

An obvious tactic, Twilight concluded, but effective. Cadence was good at this sort of teaching. Twilight hoped to lean lots from what Cadence referred to as ‘flirting.’ The little unicorn was getting a free demonstration now.

“Yeah -uh, good-night then,” said Shining Armor, fumbling his words before leaning in.

Closer. Closer. Their fur came to within an inch of one another. Cadence blushed, which was difficult considering her already rosy hue, and closed her eyes in expectation. But nothing came.

Crack.

Two horns clacked together. The pain of which was nothing compared to the embarrassment that followed.

“Er, I- um, sorry- I didn’t,” Shinning stammered without forming a coherent sentence. The pair refrained from looking at one another. Finally he managed a “goodbye” before retreating into his home and slamming the door. Amateurish. How did I screw that up? Now Cadence probably hates me.

Cadence stood taking in the scene rather dumbfounded. “Hmmm. Some ponies…” she remarked as the purple filly followed her brother inside.

“Ha-ha,” Twilight laughed, upon seeing the frustrated stallion, “Big Brother loves Cadence, Big Brother loves Cadence!” She began to dance, hopping around in a circle. Then, to rub it in more, she resorted to the best weapon available to somepony her age: “Cadence and Shiny lying in the hay. Rolling around, going all the way. First comes love, then comes marriage, then come ponies in a foaling carriage.”

“Hush up, you.” Shining feigned an attempt to silence her with a hoof. Twilight jumped away playfully.

“You’re so shy Shiny. You didn’t even kiss her.” Twilight could tell she was getting under her brother’s skin. She kind of enjoyed it. It was the type of thing she imagined siblings did all the time. “Actually, I bet you’ve never made out with any mares before.”

“Sure I have,” Shining countered defiantly.

“Nuh-uh, if you had then why’d you clonk Cadence on the head?”

“That has nothing to do with it. Plus I said be quiet.” Shining tried to ignore his sister’s taunts but wasn’t doing a very good job. Mostly because she was right.

That evening progressed as usual. Twilight and Shining went off to separate rooms to complete their schoolwork; a bevy of spells and incantations to serve them as adults in a unicorn society. Twilight practiced her precision levitating. To set the table for dinner, she floated plates and cups out of the cabinets to their proper places. Sticking to the schedule, food was to be served at promptly six o’clock. She expected her brother would be joining her soon.

However, she waited. And waited. Nopony came.

“Shining,” she called through the house, “food's ready.”

Again no response. Except she swore she could hear creaking coming from down the hall. Like somepony jumping up and down on a bed, accompanied by heavy breathing.

Walking, she swung open the door to Shining’s room, “Didn’t you hear me? I said dinner’s ready.”

“Whoa, hey Twiley,” Shining exclaimed, out of breath for some reason. Rolling over on his stomach he smiled politely, hasty movements made it obvious.

Oh right, Twilight concluded, Cadence. He must still be upset about that.

Seeing this moment of temporary weakness, Twilight formed a plan. Shining hadn’t ever kissed a mare. She had never kissed anypony either. Maybe they could use what Cadence taught her to solve their mutual problem. Taking a deep breath and swallowing, Twilight remembered the times she hadn’t asked out those potential someponies. She did not want to be rejected. But it was her brother, somepony she would have no problem doing this with. Somepony she liked. No- somepony she loved.

Just take it slow. “You know,” Twilight said, making her move, “we could practice.”

“What?” Shining replied, pretending not to hear.

“Kissing. You, me- I don’t mind.”

“Twiley, you’re my sister.”

“That’s true,” she admitted, “but I’m still a mare. And doesn’t that count for anything?” She batted her eyelashes and sat down next to Shining on the bed. He didn’t move.

It’s working, she told herself.

“I-I don’t know… it wouldn’t be the same,” Shining said.

“Oh, yeah right. I bet you’re just scared you’ll screw it up again,” instigated Twilight.

“No.”

“Then prove it. Or, admit I’m right,” Twilight smirked innocently at her ultimatum. The trap was set. Now she had only to wait.

Shining turned over and sat up. Using the opportunity, Twilight snuck a peek at his groin, seeing his flared stallion penis jutting out. What did she expect? He was a male after all. Of course, that’s why she looked there in the first place; but she regretted letting curiosity get the better of her. Civil society dictated ponies should be considerate of one another’s sex, as most just tended to ignore it day-to-day.The exited stallion leaned over, taking her hooves in his. It was a fragile connection. Rife with inhibitions, like at any moment either of them would pull away but, by some miracle, stayed. Their proximity closed and Twilight felt hot breath fog the area at the end of their snouts.

Pause. She didn’t know what to do next. First, she never imagined she would get this far. Years of fanaticizing about the all-important ‘first kiss’ rendered her quite the romantic. Two individuals drawing on their mutual attraction for one another, mentally and physically giving in to love: that was magic. Something she had always wanted to experience. Second, she should have lowered her expectations.

Lips touched. Good, as she had been expecting a horn slap. With that out of the way Twilight began her evaluation. No tongue, dry, forceful, sloppy technique. Her brother was terrible, just laying his lips on hers, expecting, for some reason, that the timid motion could convey a passionate and fiery love. Nothing like what a first kiss should be.

Ewww, no effort, D-.

Corrections were in order. Cadence would have had her partner drooling all over himself by now. Inexperienced but eager, Twilight forced her mouth into his. She had to have this: a first kiss was an important step in a young mare’s life after all. Mashing into him multiplied the sensation of pleasure between them. Though crude in their ability, any and all actions performed on their virgin bodies provoked new feelings of euphoria. Quantity was preferred over quality. Pawing each other, Shining returned the favor inspired by his sister’s enthusiasm. Spit lathered between, pooling in the creases where lip met cheek. Jockeying for position, Twilight extended a probing tongue. Finding his, she ran her own salivating appendage down its length, in a massage. Hay lingered, its flavor emulsified upon Shining’s taste buds, as he savored a hint of it from the solitary bite of dinner Twilight snuck.

Entwined and wrestling for dominance, the siblings licked at each other until they finally had to pull back, bodies aching for oxygen as much as carnality. Eyes shut Twilight could feel a switch flip in the back of her mind, restraint melting away. No longer was it her brother before her but rather a mate, a stallion. To put it crudely, a rut buddy. When that had happened she didn't know, nor did she care. All she knew was she was feeling… hot.

Getting better… C

Recovering, Shining took a moment to boast, “Ha, see? I told you.”

“It was alright,” Twilight relented. A definitive bulge swelled to attention underneath her brother, now undeniably erect. Twilight licked her lips, cleaning the remnants of their make out session form around her mouth.

Ready for round two, she knew she could push him further, “But I’ve seen you kiss mom better than that.”

That was probably a little much. Already he was right where she wanted him. And he had shown no signs of stopping half way. Teasingly, Twilight rose from the bed to straddle her sibling, giving him a nice view.

“Hey Shining, you wanna-“

She didn’t get a chance. Reaching out, Shining Armor groped her waiting ass with both hooves. Lifting her delicate frame onto his face while lying back, he squeezed her butt together, forming a pleasing plump. Releasing her overtop him, the mass of quivering fat came down squarely upon his face. Greedily, he ran his virgin tongue against her pouty pony pussy simultaneously inhaling. Her bouquet rose in his sinuses. It smelled wonderful. Scent betrayed the truth of the situation: that under a dignified and composed exterior was a horny slut, waiting for the chance to escape. Probably still a little scared too, judging by the bitter taste of ammonia around her sex. The baseness of which excised the flavor of hay that had previously been such a delight.

Content of skipping further foreplay as well, Twilight copied her brother swallowing his genitals in a hungry gulp. It was a massive amount to take in for the first time, but she had practiced a few times before. Like at summer camp, when she took an ear of corn to see if she could fit it down her gullet. She could. And she stuck it in other places as well. Bobbing up and down, pretending that corn was in her mouth again, she sucked off his meat. He bucked at the resistance and she squirted back down at him, both her orifices now drooling. Ravenously the two siblings ate at each other, dinner long forgotten, enjoying the feeling of pressure building inside of them.

“Twiley,” coughed Shining as he drowned in her juices, “it’s… I’m gonna-“

Twilight didn’t heed her brother’s warning. Unrelentingly, she enveloped his dick and sucked as long and as hard as she could, feeling the load surfacing from within him as the penis twitched.

Sploosh

A large eruption of hot spunk emptied into Twilight’s waiting maw. Enthusiastically, the magical mare drank as much of the salty secretion as she could manage, before suction between lips and phallus broke, releasing the rest of his load onto her chest in short bursts.

Heat cascading down her throat and filling her belly, Twilight’s muscles clenched, vacating her essence onto her brother’s intrusive muzzle.

Lesson learned, A+

The exchange of bodily fluids did not seem to diffuse the situation. Cleaning off his member, Twilight savored the flavor of cum. Salty with a sweet undertone, a dash of oats here or there, maybe barley; quite a unique finish as it slid down the throat. However there was still some material to cover. Fully lubricated, Twilight’s wet slit darkened the comforter staining the fabric.

“I want it,” she demanded of her mate.

Eager to please, Shining rolled over his sister and positioned his drooping phallus at her entrance. Its retreat back into its sheath halted only a moment, needing encouragement to push its lust.

“Com’on Shining rut me. Rut me!”

Forcing his flopping appendage into her winking orifice, Shining Armor grunted. It was a forceful, primal noise from his gut. His mare needed him to fulfill the most basic instinct of his existence. If ever he needed to shorten his refractory period, it was now.

“Shiny, hurry up,” the wanton mare begged.

Looking down between his legs in this haze of pleasure he was able to reaffirm something. Cadence. Since the siblings had stopped their make out session he hadn’t been thinking about her. His thoughts had been focused solely on Twilight. Funny how all this time growing up together he had never thought of her as that. But now, he couldn’t think of a better word to describe her: sexy.

Flesh gave way to a smacking sound, as fat reverberated with each impact of hips on ass. The two ponies humped furiously, spreading the natural lubricant of their love making around their groins. Gaining traction, Shining pushed off the mattress in a series of thrusts, bringing the brunt of his weight down on Twilight’s form. The force of which almost bucked her off the bed. Twilight was lost in an epiphany of lust. She could hardly care about her surroundings as she tore at the sheet to back her posterior into her brother. All she wanted was for him to have better access. To ram his long shaft deeper and deeper into her folds. Which is exactly what he did.

“Oh Shiny, that’s so amazing…” Twilight gasped, hardly able to contain her excitement.

Shining was having trouble as well. He slowed, withdrawing his cock less and less with each thrust. The rapid halting motion signaled his intent.

“Shiny no,” Twilight reprimanded, momentarily coming out of her stupor, “you can’t cum inside, I’ll get pregnant.”

Her brother was close and wasn’t intent on stopping. For an instant her body betrayed her. Some part of her actually wanted this. Sopping vagina sloshed and squirted, inviting the warm torrent of semen to spill into her. Seed her with potential foals, ponies that would grow up to be excellent unicorns, perhaps even more powerful than their incestuous parents. The instinct made sense.

Using the last of her self-control, Twilight offered an alternative, “Anal. Please Shining, shoot it in my butt.”
A mare offering him anal? Like he could miss this opportunity…

In surprise and eager for the transition, Shining withdrew his phallus, resting it on the crest of Twilight’s buttocks. Slippery with mare cum, he teased the rose-budded entrance with his flare, massaging at the hole. Twilight took a deep breath and prepared for the worst. She should have been a little more daring with her corn on the cob when she had the chance.

Forcing her head down and ass up, Shining mounted his sister. The first inch of his stallionhood slid into her puckered hole.

“Gaahhhh!” Twilight yelped, trying to acclimate to the strange sensation. Her pussy convulsed underneath them, disappointed that it could feel her other hole vying for attention. Naturally, Twilight tightened against the intrusion, clenching around Shining’s dick and holding him fast.

“You’ve gotta loosen up a little Twilight,” Shining observed, “if you don’t it’s not going to fit.”

“Hmmmfh, obviously,” she responded, breaking the intimacy a little.

Her anus pulsated as she visualized releasing her bowels. It’s no different, it’s just like taking a reverse-

Then she felt it. Deep within her a very familiar sensation arose, distracting her from the pleasures of having her rectum plugged. It told her things could end very badly.

“Shining I think I have to-“

“Ahh, hold on Twiley,” Shining said continuing to assault his sister’s rear. That same jerking motion she had felt in her pussy now present in her ass.

At once, everything came. Shining soiled the inside of his little sister, the opposite of where she had taken it previously. This time she couldn’t use her tongue to taste it, but it still gave a very pleasurable feeling of being warm and full. The feeling sparked the same reaction as when she had felt it hit her throat. Her marehood drained a sticky fluid of its own out onto the bed, further dampening the already soaked sheets. However there was still an emergency. Pressing her cheeks together as hard as she could, Twilight made a mad dash for the bathroom as she dripped cum across the floor.

“Twiley?” Shining said surprised, now reclining on the bed. His stallionhood expended but proud of its performance. Even managing an encore.

Reaching the edge of the porcelain, Twilight relaxed her sphincter emptying her bowels.

Just in time. By a slim margin, she had avoided a rather unpleasant accident. Semen and other unmentionables polluted the water below, the results of taking her anal virginity. Sitting on the toilet in her post coitus state, Twilight realized the magnitude of what she had done. Innocently she had played her brother into outright banging her. What would it mean for their relationship in the future? Could she ever look at him the same way again, after having sex with a member of her own family?

It was still too early tell.
