Twilight explains, “The next time she sat us, after putting us to bed for the night, Cadance bent herself over the dining room table, started hoofing herself, and waited for mom and dad.”

Twilight sighs, eyes closed, and slumps against Shining’s pillows. “That time I was awake. I heard everything. I think mom finally walked her home sometime after midnight. Though carried might be more appropriate.”

He’s so busy digesting her story that it takes a couple moments for him to notice that she’s slowly rubbing her crotch. “Twilight!” Shining yelps, looking away. “What the hay!? Stop it!”

“What? Urgh. I’m horny. Maybe if I come I can get some sleep. I know you are, too. What’s the problem?”

“I’m—You’re my—” he stammers. “You don’t—”

“I don’t what?” she demands. “Masturbate? Get off? Please. I’m not your baby sister anymore, Shining. Ah . . . ”

For a few moments the sounds of their parents fucking his crush mix with Twilight’s little grunts and whimpers. His mom moans and says something. Twilight gasps and nods her head, muttering under her breath. His dad laughs.

It’s awful. Listening to his parents molest his little sister is even worse than listening to them molest his fillyfriend. And if he can’t find the will to stop Twilight, how is he supposed to handle Cadance the next time she sits them?

He looks between his legs. Once again his dick is betraying him. It used to be his best friend.

“Oh, Shiny,” Twilight groans, following his gaze. “Are you getting turned on again?”

“No!” He whirls around so she can’t see. “No, it’s not—it’s not like that.”

“Poor Shining Armor. Do you need help? I can make it all better,” she sings. “It must be so hard being the only pony in this house that Cadance won’t fuck.”

She crawls up behind him, drapes her forelegs over his shoulders. He can smell her pussy juices on her hoof. She says from right beside his ear, “You’re not the only one she plays with. And almost every night. She’s a real pervert. Unfortunately she doesn’t have a dick, but she’s real good with her tongue, and her magic. And she’s so soft . . . Have you ever run your hoof through her chest fluff? I have actually fallen asleep on her chest. Too bad mom and dad never let her stay the night.”

Cadance has never let him cuddle with her. Well—he’s never asked.

Twilight sighs. “We talk about everything. You know, filly talk. When you’re not around. I bet I know exactly what mom and dad are doing to her.” Twilight shuffles them to the side so Shining’s facing where his parents’ bed is.

Cadance is on their bed, on her back, according to Twilight. Her hips are over the edge so dad can fuck her. She’s got her knees spread wide, giving him all the room he wants. He needs it. He’s really rough when he fucks her. It’s how she likes it. He puts his weight into it. The only reason she isn’t yelling is because mom’s sitting on her face, facing dad. Twilight bets their parents are making out, when they’re not saying such naughty things about Cadance. Or maybe one of them is sucking the other’s horn. Oh, yeah. Ponies can do that. Cadance does that to Twilight sometimes. It’s really good.

“Do you want me to suck your horn, Shiny?” Twilight asks, in the same sweet voice she uses when she asks Cadance to read her a story, or help with homework. “Or do you want to suck Cadance’s horn? She’ll let you, I bet. You just need to tell her.”

Shining clenches his eyes shut, but he can’t block her voice or the sounds from down the hall.

And if she’s not on her back . . . Cadance must be kneeling between dad’s legs, giving him a blowjob. Ha! Those lips that kiss Shining good night are busy kissing dad’s cock good night, too. Sometimes she finds a way to suck his cock before he and mom leave for the night. Shining has probably tasted his dad’s cum, only a few minutes old, once or twice. She’s really good at it. She can fit most of dad’s cock in her mouth but there’s still a little bit that’s dry, that she can’t manage. Dad’s got a huge cock. Of course he does. Shining has to have seen it once or twice. That’s why Cadance loves when they fuck her. And if she’s buried her face in dad’s lap then mom must be eating her out.

Twilight’s hoof is on his dick, somehow. Stroking him. She’s got her weight on his back and her chin on his shoulder, and is slowly hoofing him. He grips the sheets beneath his butt and tries not to cry out. He’s so horny. He can’t bring himself to stop her, no matter how wrong this is. He’s too weak. And she’s taking advantage of his weakness to . . . to do what? Tease him? Torment him?

Get him to fuck her?

She nuzzles his cheek, licks him, and whispers, “Kiss me.”

“What?”

His little sister grabs his chin, turns his face, and kisses him.

“Mmph—Wait. Stop!” he yelps, pulling himself free. He whirls around to face her and her smug smile. “Stop. Why are you acting like this?”

“Don’t you want to?”

“That—” he splutters. “That doesn’t matter. I can’t. You’re my sister.”

“It’s a little too late to be playing big brother, big brother.” She cocks an eyebrow. “And you’re one to talk.”

“Well—Cadance is different. She’s—” How is it different, again? “She doesn’t take advantage of me!”

“Uh, huh.” Twilight rolls her eyes. “Oh, Shiny. You’re right, you know. She’s so gentle, so caring. Sometimes I want that, too. But listening to her and mom and dad, thinking about what they’re doing to her right now . . . I really miss getting fucked.”

He slumps. Of course. “Who?” he asks, afraid of the answer. It’s not dad, and not him. Some colt from school? A Unicorn friend of hers? A professor? Whoever it is, Shining will beat him up. “Who?!” he demands.

“Carpenter, obviously.”

Shining’s jaw drops. “No . . . ”

Twilight nods solemnly. “It’s true. He used to rape me. Over and over . . . Every time he sat for us. When he put me to bed . . . when you weren’t home . . . or when you were sick, already asleep in bed, or just plain not watching out for your little sister’s well-being—”

“No!” Shining exclaims, pointing at her. “You’re—you’re lying!” She has to be. He wouldn’t. She’s never liked him. And if she’s lying about Carpenter, then she must be lying about Cadance, and his parents too. Maybe tonight really is Cadance’s first time, and—and maybe he still has time to save her. “He wouldn’t do that! How could you?!”

“Hmph,” she scoffs. “Well, fuck you, too. You make it sound like it’s my fault he fucked me.” She shrugs. “Well . . . eventually it was. I guess. I did beg him, once or twice. Towards the end, before Cadance showed up. Because, Shiny—maybe you didn’t know this, but Carpenter fucked me so good. Over and over. Night after night. Every time he sat us, whenever he could get me alone. He made me suck his dick. He grabbed me by the hips and fucked me. He sat me on his lap and hoofed me while I pretended to read some tedious picture book. He came on my face and in my mouth and all over my cunt and even in my tail. It’s why I started taking so many baths. And his cum tasted so good. Thankfully, since I drank it almost every visit.”

“No,” he whispers. “I would’ve seen it. I would’ve noticed!”

She laughs. “All you ever noticed was whether he paid attention to you or not. You didn’t notice when he took me to the bathroom for twenty whole minutes. Or when he sent you outside to do some mindless chore, and got really mad when you finished early. Or all those times he invited his real friends over. Besides, I bet you would’ve watched, if you’d known. You just found out your fillyfriend is getting railed by other ponies, and your only response is to be quiet and listen. You would have acted all upset and betrayed, but you would’ve sat and hoofed yourself to the sight of your best friend fucking your little sister senseless.”

She looks pointedly at his cock, proving her point.

He covers his cock with a foreleg and points at her with the other. “Why—”

She sighs. “Oh, Shining . . . I was just starting to like other ponies, and there were all these confusing changes going on in my body . . . You don’t know what it’s like, being a young mare, Shiny. Sometimes your body wants things it really shouldn’t want. Like diiiiick~” she sings. “Have you ever seen a large stallion and wondered how his gut would feel pressing you down, face first, into the ground? Have you ever wanted a pony to pull your hair and bite your neck? Have you ever woken up, sore and flushed and too horny to think? I have. Carpenter didn’t intimidate me. I’m not scared of some simple colt. I’m scared of my own body. So, no, I didn’t stop him. Once I figured out what was going on—once I realized it wasn’t what babysitters did, that it wasn’t right, that I could stop him—I didn’t even want to. I let him rape me. Use me. Oh, I kept fighting him. I couldn’t really tell him I wanted his cock in my mouth and his balls on my face and his cum splashing down my chin. Or that I wanted him to bring his best friend back so they could both fuck me senseless and drown me in cum. So I teased him. Sometimes I’d let him find me reading a book on my bed, lying on my stomach, with my legs spread and my tail flicked out of the way. Or I’d find some reason to bend over for him. I spilled drinks, knocked things over, and even backed into him accidentally. When he tried to rape me, I’d struggle just enough to make him mad. Once I grudgingly told him mom needed me to take a bath, and that he had to draw one for me, and could he wash my mane for me, and maybe between my legs? We made such a mess that night. There was bathwater everywhere, and I swallowed so much cum. We almost got caught so many times. It was so hot. And sometimes, Shiny—sometimes I was just so mean. I feel bad for Carpenter. He was just as helpless as you are, and it was all my fault.”

She slinks toward him. Shining tries to back up but hits the wall behind him. Trapped. He gulps.

Twilight doesn’t notice or care how he feels. She touches his cock, grabs it lightly, and starts stroking him absently. “The nights he didn’t rape me were worse than the nights he did. I couldn’t sleep. I couldn’t concentrate. I was whiny and irritable and bratty—just like you are most of the time. Sure you are. Even Cadance thinks so. You complain when she can’t come over, or when you have to go to bed, or when you think mom and dad treat me too nicely. Life must be really hard for you, Shining Armor. But I’m a filly going through puberty. It sucks for mares. All you colts get are boners that you can’t hide, and nopony blames you for those. I’m so jealous.” She looks at his cock, licks her lips. “Oh, if all I got were boners I’d never stop hoofing myself. I’d spill my messy, sticky cum all over the house. I’d drown Cadance in spunk. Heh, you'd probably start waking up to my dick in your mouth. Instead everything hurts, and it’s so hard to get myself off. The last couple months with Carpenter, I was the one raping him. Can you imagine that?” she whispers in his ear.

Shining shudders. He can imagine it. Twilight is . . . stubborn. Driven. Good with a hoof. And so cute, if he can stop denying it to himself for a moment. Yeah. He can really imagine it.

Twilight lets go of his cock and sighs. “I had everything I needed. Stress relief. Attention. Distraction. A stallion to fuck me through puberty. It was perfect.”

Twilight smiles pretty at him, then strikes the wall beside his head and glares at him.

“And then you complain once—once!—about how you don’t want him to babysit you anymore. And Carpenter goes away, replaced with this bimbo whore,” she spits, “who gets way more dick than I do. Who’s skinny and beautiful and sexy without trying. Who breezed through puberty with the grace of a swan. Who won’t stop gushing about all the stallions that fuck her, now that mom and dad started introducing her to their friends. Who’s an actual fucking Princess! When we’re together stallions stare at her, and I’m just this tiny little filly in her shadow. You don’t even notice me anymore. Neither you nor dad. You only care about Cadance! Well, lucky you. What am I supposed to do, huh?” She grabs him and shoves him against the wall. “Tell me!”

“Ahh!” Shining hisses. “Twilight!”

Twilight releases him, breathing hard. “I’m sorry. I know it’s not your fault. I’m sure this is all so strange. Cadance is a whore. She doesn’t really love you. It’s probably mom and dad’s fault. Finding out had to hurt. But you need to grow up, Shiny. You need to make it up to me. You need to help me. What should I do? I really don’t know. Should I just pretend to be normal again? That colts are yucky, and that all I care about are books? I don’t think I can do that. I need a stallion, Shiny. Maybe it’s time I stop mourning Carpenter and start looking for somepony else. It can’t be anypony at school, or else they’d all call me a slut, and Princess Celestia would never accept a slut as her apprentice. I’d ask you—” she laments, “but you’re too proud and squeamish to help your little sister, and anyways you’ve got Cadance to fuck you when you need it. Oh, wait, she doesn’t fuck you, does she? She fucks me. Whenever I ask. But she’s lacking a vital piece of equipment. Well, whatever. Maybe I should ask daddy for help?” she wonders, touching her chin and pretending to think real hard about it. “It sounds like he knows how to treat little fillies. Can you believe he’s still fucking her? And unlike you, he loves me. He wouldn’t stop until I was really helped. He wouldn’t be squeamish. He and mom would move Canterlot to help me. But I don’t think I can put up with their judging. So—maybe I should just go to daddy’s work and meet the stallions he marshals. Surely some of Celestia’s Castle Guard would want to fuck me, right? I’ve always liked a stallion in armor. It looks so powerful. So strong and brave and grown up. I bet it wouldn’t be too hard to find somepony who’s into little fillies like me. But what if it’s not just one of them? What if a bunch of those sweaty, disgusting Guards decide to fuck me at once? I’ve never been in a gangbang before. Do they hurt? Can you say no? Can you stop when you’re done?” she asks, then leans close and whispers, “I hope not.”

Shining gulps. It’s too much. “Please, stop,” he says.

“Hey, Shining. Don’t you want to be a Castle Guard one day? What would you do if a filly my age wandered into your barracks, turned around, and flashed her tiny filly pussy at you? Would you fuck her? Would you hurt her?”

“I, uh, I don’t—”

She scowls. “Yeah, I know you don’t know. You don’t know anything. If something isn’t presented on a silver platter you don’t know what to do, do you?”

“I don’t—”

“You can’t even manage to operate Cadance properly. The rest of us have figured it out. Stop whining about it and just fuck her!”

“Don’t—”

“Come on, Shining. Be a stallion for once!”

“Hey!” he snaps, shoving her back. “Why are you being such a bitch? It’s not my fault you’re so fucked up!”

He freezes.

Twilight leans back, eyes wide.

“Ah!” Shining waves his forelegs, panics. “I didn’t mean that. I shouldn’t’ve—You’re not—Twilight, I’m—”

“—right,” Twilight finishes, no longer looming over him. She looks stunned. Like she’s remembering what’s going on. “You’re right. I’m sorry.” She slides off the bed, slumps, her ears flat and her posture tiny. “Good night, Bee-bee-bee-eff-eff.” Then she’s gone, gently closing the door behind her.

Shining blinks. It’s so quiet all of a sudden.

“Good night, Twilight,” Shining mutters. He’s left alone with a throbbing erection, the sounds of lovemaking sliding in from down the hall, and a burning sensation of guilt. He’s fucked up, again. Not just tonight but, if what she said about Carpenter was true, for years now. She’s not lying. Twilight’s a terrible liar. It all fits. The way she never made eye contact with Carpenter, which Shining thought was rude. The way she got so stressed when he sat them, which Shining never understood. The way Carpenter leered at her and perved on her and joked about fucking her, which Shining always tried to ignore.

After a moment he flops back, stares at the ceiling. Crap. Leave it to Twilight to make an awful night even worse and make him feel tiny and insignificant. But she’s right, of course. She always is. Shining does wait for things to be presented to him on silver platter. His dad will get him into the Guard Academy. His mom makes sure he’s well fed and entertained. They hired a babysitter that takes care of him, even if he’s too old to need one. And it’s not Twilight’s fault Shining has been acting like a naive colt.

No more. He knows what to do.

Shining slides off his bed and leaves his room, slinks down the hall. This close there might as well not be a door between him and Cadance. He can already see her. She’s riding his dad, her forelegs balanced on his chest and her wings unfurled. Or maybe she’s on her back, with his mom sitting on her face and his dad buried between her legs. They’ve been at it for so long, she’s probably come a bunch of times. And maybe she’s covered in his dad’s cum—

Wow. Shining really is fucked.

He stops, faces the door. He’s mad, but not at her. He’s mad that he was so naive. That he never noticed. That he never stood up for himself.

Shining could go back to his bed and pretend to forget everything that’s happened. It wouldn’t be the first time. It’s not like he can fix anything by confronting her. And he’s exhausted, mentally and physically.

But the next time he sees her—

No. Twilight was right. He can’t wait for ponies to make decisions for him. He has to take responsibility. He has to start acting like a stallion.

He knocks.

Twilight’s magic immediately blooms over her door and lets him in. At first he doesn’t see her. It’s dark, and she’s not on her bed or at her desk. He steps inside. Here his parents and Cadance are much louder, and much more vulgar. No wonder Twilight couldn’t sleep.

“Twilight?” he whispers, approaching the bed trying to spot her. There—a flash of pink. He climbs onto the bed and peers down at her. She’s squeezed herself between the wall and her bed, hugging herself. She always finds the tiniest spaces when she’s upset.

“If you’re here to yell at me,” she whispers, glancing at him before staring at the floor, “don’t bother.”

“I’m not mad,” he admits. “Er. Are you comfortable down there? Do . . . do you want to sit with me?”

She scowls, but lifts a foreleg. He reaches for her, helps her climb up and out of the hole she put herself in. Once she’s up she settles into her pillows and sighs. “I would be. If you came into my room and told me I was a bad sister.”

“I’m not gonna—”

“I know.”

Sitting there, Twilight doesn’t look like a monster, or a bully, or a filly who’s had to grow up too quickly. She just looks like Twilight: the smart, obsessive, and frantic little sister he’s known almost all his life. The little sister who’s always been there for him.

And he wasn’t there for her. When she got scared about her body. When she suffered under the pressure to succeed, self-imposed or otherwise. When Carpenter took away her innocence. It doesn’t matter whether she liked it or not. He should have been there for her.

“Twilight,” he croaks. Fuck. He’s about to cry. After Cadance, his parents, and Carpenter, this is what breaks him? How much he loves his sister?

When he doesn’t say anything more she looks at him. “What’s wrong with you?”

“Twilight!”

Her scowls softens. After a moment she smiles a small, sympathetic smile and reaches for him. He slides into her grasp to hug her. She’s so warm. And smooth. And kind, when she tries.

“It’s okay.” Twilight squeezes him tightly, holds him still, and rubs her cheek against his. “I love you, Shining.”

“Twilight, I’m so sorry—”

She shushes him. “It’s okay.”

“No! No. You were right,” he mumbles into her shoulder. “I let you down. I’m helpless without everypony. I’m useless.”

“Me too, you big dummy,” she whispers, kissing his forehead. “So is everypony.”

He laughs.

She nuzzles his cheek, then kisses him. He’s stunned. But it’s gentle. Caring. Almost familial, if families opened their mouths, licked their lips, and tasted each other’s teeth. She really has grown up. “Oh, Shiny,” she breathes. The stress drains from her body, as she slumps against him. For a few moments, she seems content to just kiss him. And he’s more okay with it than he had expected. It’s an intimacy Cadance has never given him. She reaches her hoof down his side, stroking his barrel.

“Twilight . . . ”

“Shh, just let me do this. Please.”

She wiggles against him, keeps making out with him. She may be his sister but she’s having an effect. It doesn’t help that he can hear his parents and Cadance still. He winces. She must be able to feel his growing erection pressing against her inner thigh, must be able to feel the heat pouring off of him.

“Are you turned on, Shining?” she whispers, shifting her weight. “From listening to them?”

He nods.

“Or from me?” she asks, poking him.

He nods.

“You poor stallion.” Twilight gently lays him back and climbs atop him, propped up on her forelegs, so she’s kneeling over his waist. His erection is jutting up between them, while her tail is flicking across his knees. “Getting off listening to your new fillyfriend fucking other ponies. From your sister making out with you. You’re such a pervert. What if your friends found out?” she teases. “What if mom and dad found out?”

“Sh—shut up,” he whines, looking away.

She giggles. “It’s okay, Shining. Haven’t you figured it out, yet?” She leans down to nuzzle his forehead. “Everypony in our home is a horny pervert. Mom and dad like young fillies and colts. Cadance is a whore. You like that your fillyfriend has somepony else to make her come.”

“Eh heh . . . What about you?” he asks nervously.

She pouts, not unlike Cadance when she’s about to do something terrible.

“I just want to get fucked by my perverted big brother, Shining,” she whines. “I’m so horny, all the time. Especially now,” she breathes, looking down at his cock. “With this thing so close.”

She shifts her weight and traps his cock between her soft thighs. Squeezes him, then slides up and down, biting her lower lip. Twilight’s already wet, slicking his crotch with her soaking pussy. She smells so good. Like Cadance does when she’s turned on.

“Are you thinking about her?” Twilight whispers, her eyes closed. Can she read his mind, or is he just that predictable? “Me too. I don’t mind if you pretend I’m her. It’s kinda hot. Like—Mmm—like I’m a Princess, actually, and you’re my Prince. Maybe one day? You could be my consort, a pony just for me. Nopony would know who you are. Wouldn’t that be naughty?”

“Ugh,” he grunts. “You have to be a Princess, first.”

“I’m working on it.” She holds onto his shoulders for balance and slides her pussy up and down his shaft. “Hmm. If I were a Princess . . . and you were my Consort . . . I would probably have other lovers. Would you like that? Would you like to watch?”

“Twilight—” he growls.

“I know, I know. I’m sorry. I’ll stop teasing you,” she lies. Twilight slides her hips back, goes from straddling to lying on top of him. Her smooth stomach rubs down his shaft, like one continuous soft teasing stroke.

“Oh—Ugh!” he grunts, clenching his core.

Twilight ignores his suffering and grabs his cock. “Wow,” she says. “Yours is so different from Carpenter’s. The texture is completely different.”

“Twilight!” he groans.

“Yeah, I know. He liked this, too.” She slides her hoof up and down, starts stroking him. “I’m pretty good, I think. At least, it looks like I am. I ought to be. We did this all the time.” She ducks her head and drools all over his cock. “His cock was a little thicker than yours, but he’s bigger than you are, too, so that’s normal.” She shakes her head. “Even now I still wonder how in Equestria he managed to fuck me way back then. It must’ve been so tight.” She peers closer. “I think I can manage this one.”

Shining purses his lips. He loves his sister. She can be kind and caring. She’s so smart. And she’s going to do amazing things. But sometimes Shining really wishes he could just shut her up.

Maybe she can read his mind, because she holds his cock to her mouth and slips her lips around it, swallows him whole.

“Twilight!” he yells, before slamming his forehoof over his mouth. Literally right behind him are his parents, and they’re wide awake. If he was worried about making noise with Cadance—

Twilight ignores him, just settles into his lap and suckles him. Her whole body slumps, all her muscles relax. She’s smiling, at least as much as she can with a dick in her mouth. He stares in wonder. His dick isn’t that big, but in her diminutive mouth it looks amazing. And it feels so good. Her tongue is firm against his shaft, and his cock head is drowning in a bath of hot, sticky saliva. It’s better than when Cadance did it. Maybe Twilight has more practice.

He whispers, “Do—do you really like doing this?”

She pauses, looks at him, frustrated. Shining immediately regrets asking. She slurps her mouth off his cock and rests her chin beside it. Her ear tickles the side of his shaft. “Yeah, Shining. I really do. Having a cock in my mouth is satisfying. Does that make you uncomfortable? That your little sister likes dick so much? That she wants to swallow your cum?”

“No?” he lies.

“Good,” she says, then grabs his dick and licks right up the underside. “Because if it’s not your dick, I’ll have to find somepony else’s.” She kisses it, gently at first then slowly slobbering over the tip. Drooling all over it. Getting it nice and slick. Swallows it again, suckles gently. And it feels so good. If this is all she does, he’ll come in no time.

Then she reaches for his shoulder and pulls herself up. Looms over him.

“What are you doing?” he asks, shakily.

“I’m gonna fuck you,” she whispers, crawling over him and straddling his waist. “I’m gonna steal your virginity and never give it back. Weird, huh? Because I don’t plan on keeping it.”

“Uh—” He grips the sheets beneath him, watches in awe as their bodies meet. Maybe she can’t tell, but the enormity of what’s about to happen is heavy. Despite how much he begged Cadance, he’s not ready for this. Not by a long shot.

But Twilight would never hurt him. And, yeah, she probably knows what she’s doing. It doesn’t hurt that she looks so fucking hot, propped up over him like this, her entire body exposed, her face desperate. When did his little sister grow up?

“Are you gonna stop me, Bee-bee-bee-eff-eff?” Twilight whispers, angling her hips so his dick is poking at her pussy.

Stop her? Shining’s never been able to stop her. He shakes his head.

“Are you scared?”

He nods. His heart thuds, louder than his parents through the wall.

“Don’t be. Trust me. It’s just sex.” She shifts backwards, presses the head of his cock at just the right angle, grunts, and pushes down his cock.

Suddenly he’s not a virgin anymore. He’s having sex. He’s having sex! With a filly! With his sister—urgh—who’s tight and hot and wet.

“Oh, fu-hu-huck,” she groans, quivering. Grips his shoulders with shaky hooves and settles her crotch against his. “It’s been so long . . . You know, Carpenter never let me be on top. This is so much better.” She twists her hips, exploring what must be surprising nuances and subtle differences between him and Carpenter. Shining wouldn’t know; his pleasure is pretty one-dimensional right now.

“G—glad—” he stammers. “—glad to help.”

She barks out a laugh. “Sorry. Don’t mention Carpenter. Got it.” She works her way down his cock, grunting and breathing hard, then holds herself there. She hovers her face above his. “Fuck. Uh . . . Should I tell you about the time I snuck up on Carpenter in the kitchen and sucked his cock while you were in the living room? He had to bite his forehoof to keep quiet.” She sighs. “Maybe I’ll do that to you, if you want. It’ll be a surprise. Whoa!” she exclaims, looking down at her gut. “Like that, do you? I felt that.”

Shining gurgles.

Twilight pants. “See? You’re such a pervert,” she pants. “You probably were. Before Cadance.” She reaches to wipe a strand of drool hanging off her chin. “I bet if Carpenter had stayed. You would’ve let him. Fuck you as well.”

“Twilight!”

Twilight laughs. “No, of course not. He was way too into. Little fillies to fuck you.” Her speech comes in bursts, when she’s able to speak between stuttering breaths. “He would’ve teased you. Just like Cadance.”

Just like Twilight, Shining thinks.

“Fuck,” she mutters. She grips his shoulders and kisses him. “Or maybe he. Would’ve shared. He liked sharing me. Maybe he would let you kiss me. While he fucked me. If he didn’t have to hide. That’s hot. The two of you—” Kisses him. “—and me—” Another desperate kiss, while her bouncing shakes the bed beneath his ass. “Shiny,” she mutters, biting at his face. “I’m sorry. I don’t think I can hold on very long.”

She’s slapping her rump onto his crotch over and over, sliding up and down his cock on her own. Doing all the work, like she always does. If she doesn’t stop he’s gonna come all inside his little sister. And she’s worried about letting him down? “Me neither,” he grunts.

“Pull—” she pants.

“What?”

“Pull . . . pull my mane,” Twilight insists, tilting her head down.

Shining twists her sweaty mane around his hoof and grabs it, yanks her head back.

“Ahh! Mmm. Mmm. Mmm!” she whimpers.

He dips his head and bites her exposed neck.

She squeaks and comes, clenching his cock and twitching in his lap. Her knees squeeze his hips, holding him tight. She leans back and gasps for breath. She looks just like Cadance does when she comes: uninhibited, arching her back, all curves and sweat and juices flooding his lap. There’s even a pair of glorious purple wings over her back, flared out and majestic on either side of her mane. She’d look pretty with a crown, he decides.

Twilight groans and collapses on his chest with a whoosh. “Wow. Ce-lestia,” she groans. “That’s . . . Oh, fuck. I needed that.”

After a few moments she shifts her weight and starts humping him again. This time with his forehooves on her hips, squeezing her cutie marks and lifting her with each thrust. Her cunt is slicker, hotter. And watching her come, smelling her musk—

“Are you close?” she asks, watching him.

Shining nods, pants. “Yeah. I’m—I’m gonna come—”

“Do it,” she hisses. “Just let it happen.”

“But—”

“I don’t care!” She slams her hips down, crotch to crotch, and rolls her hips. “Please—Just this once. I won’t make you again. Promise. Just this once.”

“Twilight!” His orgasm looms, and he can’t stop it. She’s not stopping. “I’m—”

She grabs his head and kisses him.

He kisses back and clenches his core and thrusts up into her and comes. Feels his orgasm crash over him. All the tension from the evening, from Cadance teasing him and his parents fucking her to his sister growing up so fast just floods from his body. Like he’s coming the stress right out. He presses his hips up, lifting her off the bed and burying himself as deep into her pussy as he can. He can feel his spunk shooting up inside her, filling her up. And he just keeps coming. She whimpers, dips her head and buries it in his neck.

He collapses beneath her, sinks into her bed. Slowly he catches his breath, feels his heart settle. He looks down at the mass of mane on his chest, and slides his hoof up. “Twilight?”

“Mmm?” she sighs, shifting her weight, cocooning him.

“Was that . . . okay?”

She nods, nuzzles his chest. “Perfect. I’m gonna make you do this again. A whole bunch. Maybe then Cadance will realize there’s competition and start treating you better, huh?”

A little of his spunk leaks out of her, slides down his hips. He yelps, and tries to lift her off his lap. “Oh, crap, Twilight, I came—”

“Shh,” she hushes, holding him tight. She’s trembling. “Just be quiet.”

“But—”

“Shh.”

He sighs, and hugs her instead. Dips his head and kisses her forehead. She squeezes him back.

“I love you, Shining.”

“I love you, Twilight.”

She nuzzles his neck, and he feels wetness on his shoulder. She’s crying, a little. Coming down from the high. He might be too. He’s never come so hard. Sometimes he’s come more, but this is like his whole body came, not just his dick. His little sister knows just how to make him come. Carpenter probably never had a chance.

“Twilight,” he mutters, “I’m here for you. Always. If some stallion ever treats you badly, tell me and I’ll—I’ll beat him up!”

Twilight snorts, leans back to wipe her face. “You dork.” She smiles.

He laughs.

It’s quiet in the other room, finally. Their parents are gonna come investigate any moment now. “Uh, Twilight?” At the very least he ought not to get caught with his dick inside his little sister. “I should probably go—”

Twilight grips him tighter and whines, “No! No, no, please—just—” she shudders. “Don’t leave me, Bee-bee-bee-eff-eff. This is nice. Just stay here. Please.” She looks up at him, pouting, and activates her most manipulative little sister eyes. “At least until I fall asleep?”

Really, she’ll only admit to being a little sister when she needs something. If his parents get mad, he can just blame her. He’s too tired to care, either way. He smiles. “Okay. I’ll stay, Ell-ess-bee-eff-eff. For a little bit.”

SCREEEEEEEEE—

Shining wakes to a shriek that leaves him stunned for a few seconds, before he can clamp his forehooves over his ears.

THUMP

CRASH

He cautiously opens his eyes, expecting to find his family home burning and falling apart. Instead all he sees is a purple blur scrambling around her room in a blind panic, which is worse.

“—EEEEEEI’m gonna be late!” Twilight yells.

Shining groans, curls in on himself, still trying to wake up. At least he isn’t under attack—

Twilight grabs him and snarls, “How?!”

“Urgh. What?”

“How could you do this?” she demands, pointing behind him.

What? Shining cranes his neck, looks at the floor. Oh. Maybe he did knock Twilight’s alarm clock onto the floor where it has shattered into a dozen pieces. Maybe it didn’t go off in time. It’s hardly his fault. “Sorry? It’s not a big deal. We’ve still got plenty of time—”

She snarls and ignites her horn, filling the tiny room with her particular hue of crackling purple.

Shining scrambles out of her grip, falls off the bed, and leaps out of her room, landing on his backside. The door closes behind him. He listens to her tear apart her room in a madness. She’s probably going to wind up wasting more time panicking than if she’d just gotten up like a normal pony. What a weirdo. At least he’s out of danger for now.

“Good morning, dear.”

Shining freezes, then slowly looks over his shoulder. His mom is standing behind him, with a gentle smile, indecipherable eyes, and all the power of a mother at her disposal.

Fuck.

“Good . . . morning?” he says, trying not to look too guilty. There’s no way his mom didn’t see him tumble out of Twilight’s room and there’s no good reason he should have been in there so early. Of course a normal mom wouldn’t think he and his sister had spent the night together after fucking each other unconscious, but then apparently his mom isn’t all that normal. And she always knows. “Did Twilight wake you up?” he asks, casually.

“No, she didn’t. We’ve been up for a little while.” His mom smiles and reaches down to help him up. “Your dad’s making breakfast. Don’t wait too long!”

She slips past him in the narrow hallway and heads down stairs, humming as she goes.

That’s it? She’s way too cheerful for a mom who just caught her son sneaking out of her daughter’s bedroom. And far too cheerful for a pony who supposedly spent most of the night having sex.

He frowns. Usually just thinking about his parents and sex in the same thought is enough to gross him out. Now he’s just annoyed.

Whatever. He yawns, wipes the gunk out of his eyes, and stumbles downstairs, following the smell of hashbrowns and roasted apples.

Maybe his mom didn’t spend the night having sex with Cadance and his dad. And if not, there’s a chance he completely misunderstood what was going on last night. Maybe Twilight really was lying. Maybe he still has a shot with—

Cadance is sitting at the kitchen table.

Shining skids to a stop right before the squeaky stair. Why is she here? Why is Cadance still here? Didn’t she go home last night? Now he feels queasy. He was supposed to have time to sort his feelings. This feels like an ambush. But he can still escape. Turning around and going back to his own bed feels pretty tempting now.

He steps the final step, wincing when it squeaks, then enters the kitchen. His dad is standing at the stove, finishing breakfast. He’s chatting quietly with mom, who’s sitting at the table beside Cadance. And Cadance . . . Shining walks into the kitchen, finally facing Cadance.

Compared to the day before, Cadance looks like death. Her mane and tail are tangled messes. Her eyes are bloodshot. She’s staring off into space, her mouth slightly open. She needs a bath. And she’s holding her mug of coffee in her hooves, instead of using her teekay. When Shining steps up and says hi the only reaction he gets is a slow blink. Something terrible has happened.

But she’s got a real dopey smile on her face. Ce-lestia. Mom and dad really did a number on her.

A purple blur rushes down the stairs and through the kitchen, nearly knocking Shining over. “Hi, Cadance! Bye, Cadance!” Twilight yells. “C’mon, Shiny!” She’s out the door before he can answer.

“Oh, Twilight.” Mom shakes her head and smiles. “Shiny, dear, do you want some breakfast before you go rescue your sister?”

He nods, sitting at the table, and stares at his hooves. Any other day and he’d be excited to see Cadance. He’d want to tell her about his day, and talk about comics and the Wonderbolts, and maybe, when nopony’s looking, ogle her a little. Even at her worst she looks like a Princess. And so sexy. But he can’t even bring himself to look at her. There’s supposed to be this Cadance-sized hole inside him, right? Like she’s dumped him, or something. Angry. He expected to be angry. She all but lied to him. And mom and dad have kept all of this hidden from him for months. Instead he just feels resigned.

“Oh! Hi, Shiny.”

He looks up. Cadance is smiling at him. “Um. Hi.”

His dad floats a plate of breakfast in front of him. It smells amazing. “I hope we didn’t wake you up when we got home.”

Shining shrugs, carefully not glancing at his mom. Act casual. At least the food is good. More extravagant than their normal schoolday breakfasts.

“Did you . . . did you spend the night?” Shining asks Cadance. Of course she did. But he can’t bring himself to ask how late she was up getting fucked. Or why she didn’t leave like she promised.

She sips her coffee and nods. “Your mom and dad got back pretty late last night—yawn—so they invited me to stay here. How fun is that?”

“Yeah, that’s . . . yeah. Really fun. Cool.”

His dad floats breakfast down for the rest of them, and sits on Cadance’s other side. “We didn’t want her walking home so late,” he explains, rubbing Cadance’s shoulder. She sighs.

Shining gulps, quickly looks back at his food. The three of them chatter about nothing. It’s just a normal family breakfast. Like last night didn’t even happen and today is just another day. But his parents are just waiting for him to leave. The three of them are sitting together, with Cadance sandwiched in the middle, looking less and less dead to the world. More and more excited. Nervous. Mom has her hoof on her withers, gently rubbing at Cadance’s wing joints. And dad is blatantly nuzzling her.

Cadance catches him looking and smiles, like she and Shining are sharing some sort of secret. Which one? That he and she have been fooling around? Or that he and Twilight fucked? Maybe she’s trying to tell him about herself and his parents. Literally overnight his family has grown incredibly complicated.

She winks.

“I’m done,” he mutters, slipping from the table. Any longer and he’ll have to watch the three of them go from nuzzling to fondling. Or he’ll say something he’ll regret. He rushes upstairs and hides in his bedroom. Feels his heart racing. Feels out of control. Last night, when he felt out of control, Twilight helped him, in her own way. What would Twilight do?

She’d tell him to stop being such a whiny bitch, for one. To stop complaining and whining and expecting things to come to him. So he can’t tell them to stop, can’t ask mom and dad to stop fucking his fillyfriend. Twilight would tell him to be a fucking stallion for once, and to take what he wants.

And despite everything, what he wants is Cadance. It’s always been Cadance. No matter how imperfect she might be. No matter how infatuated she may be with his parents. She’s going to fuck other ponies, and may never fuck him. She keeps secrets. And sometimes she can be hurtful. But so can Shining, when he isn’t careful. He has his own secrets. And he just slept with Twilight—his little sister! He’s not so much better than she is.

He looks at the comic book Cadance brought, just for him.

Cadance isn’t some bimbo whore. She’s funny. Clever. Shares interests with Shining and takes care of Twilight. None of that’s changed.

And if he can convince her to stop letting his parents abuse her? There’s something satisfying about being a knight in shining armor—

“Oh, I get it.”

—and trying to save the Princess in peril, even if it is a lost cause.

Of course, he realizes with a smile, Twilight would also tell him to go downstairs and fuck Cadance. But he’s not sure he’s ready for that level of chivalry.

Shining grabs his homework and heads back downstairs.

In the kitchen, Cadance is sitting between his dad’s knees, the two of them squeezed together on their tiny chair. He’s whispering in Cadance’s ear and rubbing a hoof between her thighs. His mom is leaning against her, kissing her neck. Cadance is panting and wiggling in place, a thick blush burning her cheeks.

Shining gulps, then steps up beside Cadance. Ignoring his parents, he says, “Have a nice day, Cadance.” Before he can chicken out, he reaches up and awkwardly kisses her on the cheek. Then he’s out the door, not waiting to see how everypony reacts.

It’s bright outside. Up ahead is Twilight, sprawled out on the grass, dozing. She’s curled around a pile of school books. It looks like she tripped. He picks her up and plops her on his back, grabs her books with his teekay, and trots off towards school. Wonders what he’ll say when he sees Carpenter, and when Cadance will sit them next.

Just another day.
