Squeaky-Clean Fun
Twilight Sparkle lifted her tail and raised her ass high into the air. “C’mon, Shiny,” she said in that cute, squeaky voice of hers. “Come fuck me.”
Shining Armor’s cock went stiff. He stared at his sister’s glistening marehood and licked his lips. There were no words as he walked to Twilight and stood over her. He may have only been a few years older, but he was so much bigger, so much stronger than her. He grabbed her toned flanks in his hooves and savored the way her soft flesh moved under him.
He poked at her entrance with the the tip of his dick. He slipped inside, and her gasping, desperate moans only grew louder. He thrusted, in and out, slamming into her with all he had.
Twilight was his little sister, and he didn’t care. She was his filly.
“Oh, Shining!” she cried, nectar spilling down her thighs. “Shining! Shining!”
“Shining Armor! Twilight Sparkle! Come downstairs!”
Shining’s eyes flew open, and he let out a yelp as he tumbled out of his bed and onto the floor. He let out a groan and rubbed his aching head. Scowling, he turned to his bedroom door and shouted, “Why?!”
He got no answer.
With a roll of his eyes, Shining cracked his neck and headed for the hallway. There was no point in ignoring Mom; she’d just come running upstairs to come get him anyway. Why his mother couldn’t respect his need for daily afternoon naps he would never understand.
And this nap had been a good one, too! He fell asleep right away, and looking at the clock, he had have been sleeping for at least two hours. He had dreamt about a whole bunch of cool stuff! Like hoofball, and his last Ogres & Oubliettes game, and having sex with his sister—
Shining froze. Sighing, he dragged a hoof down his face.
That’s the third time you’ve had that dream since Summer Vacation started, he thought to himself, keeping his head low. Why are you having such gross dreams? She’s your little sister! Stop it!
He closed his eyes tight and tried to forget about the dream, but that just made him remember it more. He could see Twilight smiling as he rode her, shaking her butt to invite him in. C’mon, Shiny...
He bonked a hoof against the side of his head. A burst of pain ran through his skull, but it was enough to distract him from the memories. No more weird sex thoughts. Twilight isn’t cute, or sexy, or hot.
Shining Armor opened his eyes and saw Twilight’s ass.
“Twilight!” Shining yipped, skidding to a halt behind his sister. “Wha, what are you doing here?”
In front of him, Twilight stopped walking and shot him a raised-brow look. “You do realize that I live here too, right?”
Shining blinked a few times, then put on a smile. “Yeah, yeah, I mean... I just didn’t hear Mom call your name.”
“She called it right after yours.” Twilight kept walking, but slowed down to step into line next to her brother. “Are you feeling okay? Or has all that awful rock music you listen to finally burst your eardrums?”
That got a genuine chuckle out of Shining. The tension leaving his limbs, he said, “Hey, it may be ruining my ears, but even Starswirl Priest is better than freakin’ Bethooven.”
Twilight’s ears pricked up. Scrunching her muzzle, she said, “Is not. According to studies done by top audiobiological researchers, listening to Bethooven while you sleep helps increase brain mass!”
“You better be careful with that,” Shining said. He wrapped a foreleg around Twilight and pulled her close to tousle her mane. The scent of old books wrapped around him; it always seemed to follow Twilight around. “If this brain gets any bigger, it’ll probably explode!”
Twilight struggled to free herself from his grasp, but even as she fought, she laughed. “Very funny,” she said, slipping away. She smiled. “So, what do you think Mom wants?”
The two of them scurried down the stairs. “I just figured dinner was done,” Shining said. “I mean, what else could it be?”
“I don’t wanna take a bath with Twily!” Shining Armor yelped, ears going flat.
Next to him, Twilight nodded. “And I don’t want to take a bath with Shiny!”
“My darlings, please, calm down!” Twilight Velvet said, her attention focused on the stove in front of her. “You read what the papers said. There’s a water shortage, and we need to be less wasteful!”
“Taking baths isn’t wasting water,” Shining grumbled. “And what about you? You waste water all the time!”
“He’s right,” Twilight said. She closed her eyes, turned up her nose, and put on her best ‘scientist voice’ to explain, “By my calculations, you use approximately one-hundred more gallons of water in your garden every day than either of us do taking a bath.”
A thick crimson passed over Velvet’s cheeks. “Well, yes, but my plants need the hydration. How else am going to grow Shining Armor that broccoli he loves?” Shining’s face managed to grow even paler at the mention of his mother’s broccoli.
“You could always buy it,” Twilight said. “There’s a nice little supermarket just down the road—”
“And have us eat magically-grown food?” Velvet scoffed. “I may be a unicorn, but I grow my food naturally, just like the earth ponies. There’s no love in a magic tomato!”
“There are no worms either,” Shining grumbled.
“In any case, my mind is made up,” Velvet said. She turned off the stove and gave both of her children a wide smile. “Starting tonight, you two will start taking baths together.”
Both of her children groaned as one. “But Mom, that’s... weird!” Twilight said, leering at her brother.
“There’s nothing weird about it,” Velvet said. “You and your brother used to bathe together all the time, and you never complained then. What’s the problem now?”
Shining glanced at Twilight, memories of their foalhood playing in his head. Yes, they used to take baths together, but things were different now. No longer was she the tiny little filly who cried in the dark, or who feared the monsters under her bed.
She was a mare.
Well, as much of a mare as a fifteen-year-old pony could be. She still had the long, gangly legs of a teenager, and even the occasional magic surge. But the fact remained that Shining couldn’t bring himself to stop staring at her smooth coat, her soft lips, her toned flanks—
“The decision is final,” Velvet said, returning to her cooking. “Now, run along. Dinner will be done in just a little while.”
Shining’s eyes went wide as he realized he was staring at his little sister’s rear. Cheeks going hot, he looked up—only to find Twilight looking him in the eyes, her inviting lips slightly parted. Her brows were furrowed up, in the way they always furrowed when she was thinking hard. Shining would have found it adorable if his face didn’t feel like it was on fire.
He turned his face to the floor and walked away, out of the kitchen. His hackles stiffened when he realized that Twilight had followed him. The two of them trudged into the living room and collapsed onto the couch.
“This is completely illogical,” Twilight said.
“Tell me about it.”
“Well, as I mentioned, taking a bath only uses on average about forty-two gallons of water, while—”
Shining smirked. “I wasn’t being serious, Twily.”
Twilight shrank. “Oh.”
Shining let his head fall back onto the couch. For the quickest of moments, he imagined what it would be like to take a bath with Twilight. To gaze at her wet mane, to watch the soapy water run down her body...
Stop it! He scowled and bit down on his tongue. Stop it stop it stop it!
“Are you okay?” Twilight asked, looking at him.
It took Shining a moment to realize he had bitten down so hard that tears had started to form in his eyes. “I’m fine,” he said, wiping them away. “And, uh, sorry about all this. I can just not take baths for a little while if you don’t want to share—”
“No, no, it’s fine. I’d rather this than have to live with a biomedical hazard for a brother,” Twilight said. She gave a weak smile. “And maybe Mom has a point. It’ll be just like old times, right?”
Shining nodded and took a long breath. “Right.”
A few hours later, Shining and Twilight stood across from each other, right next to the bathtub. Their mother had taken the time to not only fill the tub, but check the temperature and fill it with mountains upon mountains of bubbles—just like when they were kids.
Twilight pawed at the tile floor. “So.”
“Yeah.”
Silence.
“Um.” Twilight put a hoof on the side of the tub. “Do... do you wanna get in first?”
If only to get this whole thing over and done with, Shining started to nod, but stopped when he realized that would make him look far too eager. Instead, he just stayed silent as he climbed into the tub. He made sure to keep his tail down as much as possible, protecting himself from any wandering eyes.
She’s your sister, he repeated to himself. He sank into the warm water, letting the bubbles wrap around his coat. She’s not gonna be looking at you like that! It’s gross!
Twilight took a deep breath and climbed into the other side of the tub. She kept her face turned away from Shining, and when she spread her legs to step into the water, Shining got a clear view of her tight marehood.
The blood was already rushing. Shining jolted up straight and moved both of his hooves to cover his cock, but that just made him harder. Stiffening under the water, Shining silently thanked his mother for adding so many bubbles—the two of them could barely see each other’s faces, let alone what was under the water.
Twilight settled in across from him, just next to the faucet. Hints of pink had already flushed into her cheeks, and she held her limbs tight, as if she were afraid to lose them. Shining did the same, if only to hide away his shame.
And yet, even that wasn’t enough to keep them apart. Shining only just now noticed how small their bathtub actually was; while it may have been fine for a couple of foals, it wasn’t anywhere near enough to fit two almost-fully grown siblings. Their hooves kept clomping against one another under the water, sending both ponies recoiling every time.
Aside from their occasional gasps or apologies, the room was quiet. Neither one said a word for a few minutes, instead opting to simply soak and let the silence fester.
Just as Shining’s boner softened and the image of his sister’s naughty bits began to fade from his mind, Twilight gritted her teeth and said, “If we’re here to bathe, there’s no point in just sitting here.”
“Huh?” Shining tilted his head. “What do you mean?”
“I mean, the goal of taking a bath is to get clean.” Twilight squirmed. “So, we should, y’know... wash ourselves?”
Is she asking you to wash her?
“Are you asking me to wash you?” Shining asked. It took him only a second to bite his tongue.
Twilight went from pink to red. “No, featherbrain! I’m saying I’m going to wash myself, and you should wash yourself!” She scrunched up her muzzle. “Wash me... I’m not a little filly anymore, y’know.”
Shining gazed at the way Twilight’s damp mane fell over her shoulders, delicate and graceful. “Yeah,” he said, swallowing. “I know.”
“Why don’t we turn away from one another?” Twilight asked. She lit her horn and brought over two bars of soap from the cupboard under the sink. She floated one over to Shining. “We can give each other a little privacy, at least.”
Shining nodded and took the bar of soap in his magic. The two of them let out a few small grunts as they got up and turned around, trying their best not to tangle their tails. Shining sat down and started lathering under his forelegs, trying his best to focus on a crack in the wall in front of him.
How do girls wash themselves? he asked himself. They do loads of crazy stuff with their manes, right? Or is that just in the shower?
The image of Twilight showering popped into his head, warm rivers of water trailing along her neck, across her stomach, down to her—
He slapped himself with the bar of soap. Snap out of it! That’s stupid and freaky and gross, dude!
No matter what his thoughts screamed, however, they couldn’t stop the fantasies, and they couldn’t stop the blood from returning to his cock. He swiped the soap across his neck and tried to ignore the tip of his penis sticking up through a hole in the bubble cover, tried to ignore the feeling of his sister’s tail brushing against his, tried to ignore her soft humming.
But he couldn’t, and now all he could imagine was Twilight on top of him, her body pressed into his, humming into his ear—
The soap fell from his magic and into the water. He sighed and swished his hoof around, pushing away the bubbles to search for it.
This is what I get for not jacking off for two days, he thought. All I can think about is sex.
He cursed his pubescent hormones and brushed his hooves along the floor of the tub, but the bar of soap was nowhere to be found. It must have slipped around to the other side of the tub. He lifted himself up and turned around.
Twilight was standing up and rubbing her pussy. Her eyes were closed.
If Shining Armor had wings, they would have gone rigid. “Twilight!”
Twilight opened her eyes and looked at Shining, then at her hoof, then back to Shining, and then back to her hoof. She dove back under the water. “Why, wha,” she blubbered. She scowled. “Shining, I told you to turn away!”
“I was!” Shining said. “But why were you—”
“I was cleaning myself. Y’know, washing off the lather?” Twilight’s bright cheeks betrayed her wrathful glare. “Why were you watching?”
“I dropped my soap,” Shining said. “I was looking for it, and I turned around. That’s it.”
“Oh.” Still frowning, Twilight looked down into the water. She lit her horn, and a bar of soap floated out of the water. “Here.”
Shining watched her lift it, and quickly realized: based on where she had found it, his soap must have been sitting right next to her—
He shook his head and growled. “This is stupid. Mom can’t make us share a bathtub.”
“She can if you ever want to attend another hoofball game,” Twilight said. “Of if I ever want to apply for another Canterlot Museum All-Access Pass.”
“Whatever. I can deal.” Shining tried to shake the picture of his sister touching herself out of his head, but it wouldn’t go. He cursed under his breath. “I’m getting out of here.”
He stood up, bringing Twilight eye-level with his raging, bubble-coated boner.
Shock spidered down Shining’s spine. He sat back down, hooves flying to cover his cock.
Twilight’s jaw fell open. “You... you pervert!”
“I’m not a pervert!” Shining said, glancing at the door. “And keep it down, or Mom will—”
“Why did you have an erection?” Twilight asked, spitting out each syllable like it was dirt.
“I can’t help it!”
“I’m your sister!”
“So?”
“So why did you have an erection?!”
“Because you’re hot!” Shining said.
Silence.
Twilight blinked. “I’m... what?”
Oh no oh no oh no oh no
“You—I’m not—I didn’t—” Shining stammered, hooves shaking. He couldn’t see straight, couldn’t keep a thought going for more than a second. When he finally managed to rein in his tongue for long enough to form a sentence, he blurted out what he felt was most important: “Don’t tell Mom!”
“I won’t,” Twilight said, frowning. Her mouth hung for a moment, as if she were meant to be talking, but couldn’t find the words. She wrung her hooves. “You... you think I’m ‘hot’?”
Shining paused before taking a hard swallow. “Yeah,” he said with a small nod. “Super hot.”
Twilight sank into the water, until just her wide eyes were visible. Her face was a beacon of red under the water. She stayed like that for awhile, just staring ahead.
“I’m sorry,” Shining said, shaking his head. He covered his eyes. “I’m a freakin’ weirdo, I know, and we should probably just never talk about this again.”
“No one’s ever told me I’m hot,” Twilight said in a timid voice, lifting her head. “No one.”
“What? That can’t be true. I’ve been to your campus; there’s stallions all over the place.” Shining felt his fear slipping away, replaced by the familiar fire in his chest he often called his ‘BBBFF sense.’ “You’ve gotta have colts falling over themselves trying to talk to you!”
“No.” Twilight pursed her lips. “All the colts at school just kinda ignore me. I mean, it’s not like that’s surprising. I’m too awkward for any of them.”
“Now, I know that’s not true.” Shining grinned. “You’re the smartest, kindest filly I know, Twily. And, like I just said, I think you’re pretty cute, too. Those guys at school aren’t too good for you; you’re too good for them.”
“I... you think so?”
“I know so.”
The smallest of smiles crossed Twilight’s blushing face. Under the water, she brushed Shining’s leg with her tail. “Thanks, Shiny.”
The touch sent a shiver running through Shining’s body, coating his bones and snuffing out that fire in his chest. “Oh, um, no problem,” he murmured. His cock was still hard, but at this point, he didn’t even care. He stood up, letting his boner hang free. “I think I’m just gonna go—”
“I think you’re hot too,” Twilight blurted out.
Shining froze. “You do?”
“Yeah. I always have.” Twilight bit her quivering lip. “I mean, I think so. I haven’t read many books on physical attraction, but based on what I do know, I’m attracted to you.” She took a breath. “This feeling is called arousal, I think.”
what
Shining flapped his suddenly dry mouth. Seconds passed, and he could only bring himself to sit back down and make one sound: “Uh-huh?”
“Uh-huh.”
“Oh.”
The two sat.
“So, um,” Shining said, “what now?”
“We... we should probably just keep washing ourselves.”
Shining nodded and picked up his soap again. A headache pounded in the back of his skull, and his ears were flat as he got up to turn around again—
“Wait,” Twilight said.
Shining stopped in his tracks and looked to her expectantly.
Under his gaze, Twilight trembled, and it took what seemed like hours for her to mumble, “Well, I mean, I know I said no to this before, but you could”—Twilight darted a glance at the door, then through the water at Shining’s dick—”wash me.” She managed to look Shining in the eye. “Is that okay?”
Shining just nodded.
Twilight took shallow breaths as she stood up and turned around, sticking her ass up in the air and presenting her nether regions to Shining. “I think there might still be some suds,” she said, reaching back and spreading her lips apart. “Could you get them?”
“Yeah,” Shining murmured.
He stood up and leaned forward, stopping only when he was mere inches from his sister’s damp pussy. His cock almost hurt, it was so stiff. Every instinct he had shouted at him to grab Twilight, to pin her against the wall, to pound her until the pressure inside of him was gone.
But he pushed those thoughts away. This was his sister. If they were going to do... this, it would be on her terms, not his.
He lifted a wet hoof and traced it around Twilight’s labia, basking in every tremor that ran through her. He wiped away the small bubbles and suds that hung on Twilight’s coat, moving his hoof from the lowest part of her marehood all the way up to her tight little asshole. He brushed the tip of his hoof just past her clit. Twilight’s twitching tail nearly took out his eye.
Already arousal dribbled from her lips, catching on his hoof. He held his breath and pressed the flat of his hoof into her crotch. Twilight let out a shivering whine, but still she leaned into his touch, letting his hooftip poke inside of her.
“Oh my gosh,” Twilight said in a breathy voice, eyes clenched tight. “That... oh my gosh.”
Shining pulled away, and thick strands of Twilight’s fluid clung to his hoof. “Should I keep going?”
Twilight nodded.
Shining moved to touch her again, but stopped. He stared at his sister’s delicate sex, then at his clumsy hoof.
He could do better.
Shining stuck out his tongue and ran the tip of it along the outer edges of Twilight’s folds, earning a gasp in response. His sister’s juices tasted sweet in his mouth. Her moans and murmurs filled his ears, spurring him on. He slid his tongue into her waiting pussy. Her walls pulsed around him, moving as if they were trying to grab his tongue and pull him deeper.
He lapped at her marehood and let the clear liquid roll down his chin. He nibbled at one of Twilight’s lips and her legs shook beneath her.
What are we doing? Shining asked himself, dipping his muzzle deeper into his sister’s gaping sex. If Mom or Dad were to see this... And what about Cadance?
Well, it wasn't like he and Cadance would ever be a couple, anyway. Cadance would never let Shining Armor eat her out like this. No, only his little sister would let him do that.
Sparks of magic flickered from Twilight’s horn with every lick. “Shiny,” she moaned, mouth lolling open as Shining pressed his tongue into her clit. “Oh, Celestia, Shiny please...”
“Please what?” Shining asked, flicking his tongue around the deepest parts of her snatch.
“Please...”
Shining lit his horn and opened Twilight up even wider. He drank up the juices that spilled from his sister’s pussy. The smell of her excitement wafted through his nostrils and kept his cock hard. “What?”
“Please,” she said, reaching around and tapping her brother’s face. “Please stop.”
Shining’s eyes snapped wide. He scrambled backwards, his little sister’s lovejuice still dripping from his chin. “Sorry, sorry! I took it too far, didn’t I? Oh jeez, please, don’t tell Mom!”
Twilight spent a moment just panting and shaking. Her swollen pussy winked at Shining from across the tub, as if trying to lure him back in. She mumbled a few curses under her breath.
“Are you okay?” Shining asked in a low voice. “Did I hurt you?”
Twilight turned around and walked over to her brother. She pressed her body against his.
“Twily...?” Shining asked as his sister’s pussy rubbed against his cock. “What are you doing?”
“You’re such a pervert,” Twilight said. She put her forehooves on Shining’s shoulders and began moving up and down and up and down, sliding her snatch along his shaft. “Mom is going to be really mad at us.”
“Only if she finds out—ah!” Shining moaned. His cock twitched under the heat of Twilight’s sex. Twilight pinned her brother’s penis between his stomach and hers. Even in the warm water, it felt hot against Shining’s body. His thoughts were fuzzy, clouded. All he could focus on were Twilight’s innocent purple eyes.
He leaned forward to kiss her, but instead their muzzles just smacked together. Twilight recoiled, hooves flying to her face. Shining cringed. “Oh, crap, sorry! I didn’t mean—”
Twilight kissed him back, leaning into him even harder than he had. They pressed their muzzles together, and Shining savored the sweet taste of his sister’s lips. He had wondered what these lips tasted like for a while.
Twilight was the one to take the next step, pushing her tongue past Shining’s teeth and into his mouth. Their tongues brushed against each other, twisting and dancing. Shining wrapped a strong hoof around Twilight’s head and pulled her closer. Twilight didn’t fight it, only pushing her muzzle in harder. The two of them stayed locked like that for awhile, only pulling apart to breathe or mutter a hushed curse.
And through all this, still Twilight slid along her brother’s cock, squeaking with each bounce. Shining let his hooves fall, and he stroked his sister’s tight flanks, running his hooves along her cutie mark, down to the base of her tail.
Just as Shining felt like he was going to lose control, like he was going to grab Twilight and make her his, Twilight stopped bouncing. She gazed down at Shining’s cock under the water and stuck out her tongue; then, with a slight readjustment. she let the tip of his dick slide inside of her.
“Holy...!” Shining spat, the air leaving his lungs. Pure ecstasy ran from his dick and through his body, destroying his thoughts and his words.
“Did I do something wrong?” Twilight asked, eyes going wide.
“No, no, I just...” Shining took a deep breath. “Keep going.”
Twilight nodded. She closed her eyes and grimaced a bit as her brother’s rod spread her open even wider. He was big, and her young pussy had to stretch to accommodate him. She rocked her hips a little bit, letting the flat head of his cock slide around her outer lips. As Shining took in another gasping breath, Twilight lunged forward and kissed him again. Her tongue was frantic against his, lashing out.
She eased his member into herself, grunting as each flaring inch slid in. She reached his medial ring and fell over his shoulder, breathing hard.
Shining swallowed. “Does it hurt?”
“A little bit. But it feels nice, too,” Twilight said. She kept moving downwards. “I’ve never done this before.”
you’re taking your little sister’s virginity
The thought only made his cock flare inside of her, earning him a squeak.
She could only take a few inches more before she stopped. But as soon as she reached her limit, she moved back up again, letting most of Shining’s cock slide out of her. It took a few cycles of this before she hit a steady rhythm, dipping up and down, fucking her brother.
Shining was content to just sit there and let her work, but soon enough saw her straining face and figured that was unfair. He moved his hips as much as he could from his position, thrusting inside of her. Twilight’s walls were soft and slick, and they felt like velvet on his dick. They pulsed against him and sent waves of pleasure rushing through his body.
“Oh gosh, oh gosh,” Twilight said again as she moved. The sparks flying from Twilight’s horn grew brighter. “Oh gosh!”
Shining didn’t have the brainpower ready to say anything. Instead, he grabbed Twilight’s flanks, digging his hooves into her smooth, nubile flesh. The next time Twilight came down, he pulled, forcing more of his stallionhood into her. She moaned into the air and hugged him tightly.
The instincts he had once fought off were coming to life. He moved his little sister around with force, slamming his cock into her tight little pussy. Every pump came with a grunt from him, and a squeak from her. Twilight was his to conquer, his to dominate—
“No,” he said under his breath.
Twilight kept moving her hips. “Huh?”
Shining didn’t answer, but thrusted a bit harder—just enough to force a shuddering moan out of Twilight.
No matter how much his cock demanded it, Twilight wasn’t ‘his’. She was doing this because she wanted to. Shining Armor loved his little sister, and as he stared up at her face, contorted with pleasure, he realized that she loved him, too.
“Shiny—!” Twilight said, head raised high. “Keep going! Goddess above, keep going!”
Shining sped up his thrusts, ramming into her cunt with all his might. But the pressure in his loins was climbing, rising to the boiling point. He grunted and groaned, pumped in and out, in and out. Water splashed around them, over their hot bodies and over the edge of the tub. Shining buried his head in Twilight’s wet mane and bit down a scream, a shriek.
A thought hit him.
“Twilight,” he said through his heaving breaths. “You gotta get off of me, or I’m gonna—”
“Cum inside of me!” Twilight shouted, her voice echoing through the bathroom. “Oh goddess, please!”
do it
Shining kept thrusting. He felt himself nearing the edge. “Mom is gonna hear you—”
“I need you to fuck me,” Twilight growled. She took in Shining’s full length. “Shiny, please! Goddess, goddess, just get me fucking pregnant!”
Do it
“But—”
“Fuck me!”
CUM INSIDE TWILY
Shining Armor bit down a howl and thrust into his little sister for the final time, holding her down with his entire cock bucking inside of her. A thick spurt of cum burst from the tip of his dick, splattering along the walls of her pussy. He felt his jizz flowing inside of her, surging outwards, upwards, into her teenaged womb.
All of his thoughts, all of his instincts were gone, replaced by electric pleasure. He groaned into the air, letting his cock flare against her cunt, more and more cum spilling into her with every pulse. He edged open an eye and saw Twilight biting down on her lip, face bright red. He smiled and closed his eyes, calm washing over him—
Twilight came. Her inner muscles clamped down on Shining’s stiff cock, squeezing out its last gushes of jizz. Hot pussy juice flowed, running across Shining’s dick and into the bathwater.
“Shit!” Twilight shouted, making Shining flinch. She held him close, panting as the orgasm passed through her and her clit calmed itself. “Oh, fuck, fuck, fuck...”
He had never heard her like this; was this Twilight during sex? Shining opened his mouth to tell her to calm down before someone heard—but stopped. He gazed at her, still writhing in pleasure. His cock still sat inside of her, only just now starting to soften. He had just cummed inside his little sister, and in return she had burst all over his dick.
He knew he probably should have been worried, or freaked out, or something. And yet, he couldn’t bring himself to do anything but smile.
He wrapped a foreleg around her and rested her head against his chest. Her warm, shaking breaths traipsed along his wet fur.
“That was...” Twilight began, but didn’t finish.
“Yeah.”
He lifted her head, and they kissed again. The two of them closed their eyes and let their tongues dance one more.
The bathroom door opened.
“What was all that yelling about?” Velvet asked, stomping inside. “And who was swearing?”
Twilight and Shining stared at their mother. Their legs were still wrapped around each other, and Shining still rested inside of Twilight. If one looked into the water, they could see bits of semen floating around with the bubbles.
Luckily for them, Velvet wasn’t looking in the water. Instead, she stood across the bathroom, her eyes wide. “Oh, my...”
“Mom!” Shining yelped, holding Twilight’s stiff body. “It’s not what you think!”
“Not what I think?” Velvet asked, scowling. “Not what I think?!”
Twilight buried her head in Shining’s chest, her cheeks burning bright. “Oh, no...”
Velvet smiled. “You mean to say that I haven’t just walked in on my two adorable little darlings hugging each other?”
Twilight and Shining blinked. “Uh,” they said as one.
“Why, I haven’t seen you two hug this tightly since you were foals! Oh, I knew these baths were a good idea!” Velvet giggled and ran out. “Let me get my camera!”
Silence overtook the bathroom.
Shining and Twilight exchanged a glance. Then, with not a few grunts and hushed swears, Twilight lifted herself off of Shining, setting his softened cock free. She hopped out of the water and grabbed a towel.
“C’mon,” she said, drying herself off. “Let’s get out of here before Mom accidentally makes a porno.”
Shining smiled and followed after his little sister.
Later that night, Shining Armor laid in bed, both hooves on his cock. He kept a contented grin as he jacked off, stroking his oil-covered hooves along the length of his shaft. His rod pointed straight up, as stiff as ever.
And yet, in the back of his mind, he knew that nothing would ever replace the warm slickness of his sister.
He closed his eyes and thought about Twilight, thought back to the sound of her small squeaks in his ears. The memory of her teenaged body riding his meat played over and over again, until it was burned into his imagination. All he wanted was to live it again, to hold her close and feel her, to fill her up. He wanted to just hear her voice, to smell that soft scent of old books that always followed her around.
Was this love? It had to be. Shining knew with all his heart that he loved Twilight. There were no questions about that.
Shining stroked faster, faster. He felt the end nearing—
A knock came at the door.
Shining grabbed his blanket and threw it over his body, making sure it was disheveled enough to hide the silhouette of his dick. “Who is it?” he called.
“It’s me, Shiny.”
He smiled and took off the blanket. “Come in, Twily.”
Twilight slipped into the room, and when she saw her brother’s dick, closed the door behind her. “You really should lock the door if you’re gonna do that,” she said, securing the latch on the door. “You could have been caught.”
“We could have been caught earlier,” Shining said with a grin. “One of us was being pretty loud.”
Clouds of pink swirled through Twilight’s cheeks. “Uh, sorry about that. I got pretty crazy, didn’t I?”
“Crazy? Try insane.” A familiar thought crossed Shining’s mind, and he sat up with a frown. “Please tell me that I didn’t actually get you pregnant, though. Because if Dad finds out we’re having a baby, he’s gonna—”
“No, I’m not pregnant. Did you really think I’d let you ejaculate inside of me if there were any chance of pregnancy?” Twilight asked. She chuckled. “Post-sex birth control spells may be in the ‘Adult’ section of the library, but then it’s a good thing I’ve never believed in age restrictions for literature.”
Shining Armor let out a relieved sigh and collapsed back onto the bed. “Thank goodness.”
Twilight put her hoof on his cock.
“Twily?” Shining said, wincing. “Do you wanna...?”
“I think I’m good for now,” Twilight said, stroking him. Her face was bright crimson, and her voice shook as she said, “Today was fun, but I’m a little sore. I... I just thought I’d give you a goodnight kiss.”
Shining gaped as Twilight hopped onto the bed, opened her mouth, and fit Shining’s cock inside. There was no finesse, or patience with her actions; she took as much of his length as she could fit inside her mouth, and then some. Shining felt that familiar pressure return, and he laid his head down, letting the feeling of Twilight’s soft lips against his dick wash over him.
She swirled her tongue around his head a few times, then took him deep, letting the tip of his dick slide down her throat. Shining had no idea how she did it; he could only imagine that another book taught her how. She sucked quickly and with force, very nearly swallowing his dick.
Shining had already spent the last few minutes jacking off, so it didn’t take long for his cock to flare in Twilight’s mouth and let out a small splatter of jizz. The next spurt was an explosion, and Shining moaned as he coated the back of his sister’s throat with his thick cum. She could barely swallow before the next burst came, filling her mouth again. Small droplets of his cum spilled from her lips, dripping down her chin.
She waited for Shining’s dick to stop twitching, then ran her tongue along the head of his cock again, picking up any stray strands of semen. She wiped her chin and licked off the cum in her hoof.
“You...” Shining blubbered as Twilight pulled away, letting his cock flop onto the bed. “You swallowed everything.”
Still blushing, Twilight nodded. “Goodnight, Shiny.” She made it to the door and undid the latch, then laid her hoof on the doorknob and paused. She looked back over her shoulder. “I love you.”
“I love you too,” Shining said without a pause.
