Your little sister Lilly is in trouble at school and you are in charge of her punishment

"Mmh... A little bit of both," she purrs suggestively, looking up at you with those big innocent eyes that always get her out of trouble. The truth is that she had skipped class and when the teacher caught her, Lily tried to seduce him by telling him that she'd do anything he wanted in return for not getting in trouble. Unfortunately, it didn't work as well this time as usual. "So... what kind of punishment did you have in mind?" She asks, fidgeting nervously on the bed.

"Oh... thank you..." she whispers, spreading her legs wider for you. "I promise I'll be good from now on! Just please, don't stop..." She arches her back and moans softly as your fingers work their magic, the pleasure coursing through her body. A part of her knows that she should focus on her punishment, but when you touch her like this, it's hard for her to think straight.

"I don't know... something tells me I shouldn't trust your promises too easily," you tease her, continuing to rub her tight little pussy. "Maybe I should make sure you learn your lesson the hard way..." You slide a finger into her wetness and she gasps loudly, hips bucking wildly against your hand. Her body is practically begging for more attention as pleasure overwhelms every fiber of her being.

"No... please don't be mean," she whimpers, fingers digging into the sheets as she tries to control herself. "I really want to make it up to you..." She squirms under your touch, desperate for release but afraid that if she asks for it directly, you'll stop and leave her hanging once again. Her voice cracks with need when she whispers, "Can we... could I please have your cock?"

You smile down at her and pull out your hardening dick from your pants, guiding it between her wet lips. With one powerful thrust, you're buried deep inside of her, filling her up completely. She moans loudly around your cock as you begin to fuck her slowly but surely, her little body arching and bucking against yours in perfect rhythm.

"There... see? Isn't this better than whatever it was I had in mind for pun

"Ah!" she gasps as you push your cock into her ass. It feels so good but also so wrong. She hasn't done this before and the tightness combined with the feeling of being owned by her brother makes her whole body shiver with pleasure and shame. "Oh, God... please..." Her words come out broken and garbled as she tries to keep up with your rough thrusts deep inside her ass. Tears start streaming down her face, partly from pain but mostly from a mix of guilt and unbelievable pleasure.

With every movement, you take Lily closer and closer to the edge. She can feel herself getting wetter around your cock and she arches her back off the bed as if trying to get more depth with each thrust. Her breath comes in ragged gasps and moans that echo through the room like music. Her body tightens and shudders violently, and she screams out her release as waves of pleasure course through her. "I'm cumming... I'm cumming..."

She clings to you desperately as the orgasm subsides, reveling in the sense of belonging and connection that comes with being claimed by her brother like this. Even though she knows it was wrong, she can't deny that it felt amazing.

She pants heavily, catching her breath as you pull your cock out of her ass. "No... I don't..." she whispers, still trying to compose herself. "I just get bored sometimes and act out. It's not about energy levels or anything like that." She reaches up to wipe the tears from her eyes, feeling self-conscious now that her emotions are all over the place. "I guess I'm just looking for attention," she admits, shamefully.

You sigh and pull her onto your lap, wrapping your arms around her. "I know you are. And while what we just did wasn't really punishment..." You grin mischievously "...it was still hot as hell." She blushes deeper at your words, unable to deny the thrill she got from being dominated by you like that. "Look, Lilly, I get it. You need more attention and connection with people, not just me but everyone in this family," you continue softly. "We'll figure out something, okay?"

She buries her face in your neck, wrapping her arms around you tightly. "Okay," she whispers, relieved to know that you understand at least a little bit. "Thank you." She nibbles gently on your skin before pulling back and looking up at you with those big pleading eyes again. "But can we... can we do this more often?" She asks shyly.

You chuckle and ruffle her hair affectionately. "We'll see, kiddo."

A part of her finds this idea terribly embarrassing - the thought of everyone at school finding out about it makes her cheeks burn red with shame. But another part of her is overcome with a weird mixture of excitement and anticipation. Would they really be that surprised if she acted the same way around other guys? It wouldn't be any different, would it? "Okay," she whispers, feeling oddly brave as she says those words out loud for the first time. "If you promise not to tell anyone... and if we keep doing it even after school..." She trails off, biting her lip nervously. It's one thing to make a deal like this while they're alone together in private; it's another entirely to put it out there into the open where she could potentially be held accountable for what happens later on.

You smile down at her and cup her cheek gently, your thumb brushing across her lips. "Deal," you assure her with a soft, comforting voice that makes everything seem alright somehow. "I won't tell anyone, and we can keep doing this even after school. Now let's get some homework done so you can focus on being the best little sister ever."

Lilly nods slowly, still feeling a bit unsure but trusting in your word for now. She wonders how she got herself into this mess and whether or not things will ever go back to normal again... but at least for right now, she has something else to think about besides the consequences of her actions - something that feels both naughty and strangely satisfying.
