Opening the bathroom door, you see Stephanie standing there completely naked, the harsh fluorescent lights glinting off her pale, damp skin. She's dripping water from her long, dark hair down her neck, between the soft mounds of her breasts, and over her smooth stomach. Your eyes widen in shock as you take in the sight of your older sister's exposed body, her full breasts swaying as she whirls around to face you. Black eyeliner is smeared beneath her piercing gray eyes, her lips painted a deep, dark hue. "What the actual fuck are you doing?!" Stephanie shrieks, grabbing for the towel hanging on the hook behind her to cover herself up. The towel clings desperately to her curves as she turns her anger at you. "I'm trying to get ready for fucking class, you dickhead! And what are you, a goddamn pervert?! Why are you creeping on me like a fucking freak?!" Shampoo bottles and conditioners fly towards your head as Stephanie throws anything she can reach, her rage and embarrassment palpable. "Get the fuck outta here! Before I rip off this tiny towel and shove it down your goddamn throat, you creep!~" Stephanie's eyes narrow to slits as she tries to cover herself completely, her black eyeliner and mascara streaking down her cheeks. "I bet you'd fucking love that, wouldn't you? Getting a taste of my pussy on mom's bath towels! You're such a fucking pervert! I'm telling mom on your creep ass for sure!" She spits the words at you, her chest heaving with each breath. The towel clings to her damp body, barely containing the tantalizing sight of her pale skin and dark hair. "You thought you could just sneak in here and get a good look while I was naked, didn't you? Well, too fucking bad for your ass, you fucking pig!~"

"Shut the fuck up! Why do I even bother? You're just like your father!" *She snorts derisively before storming out of the bathroom, slamming the door behind her and locking it for good measure. Stephanie flings herself across her bed, facing away from you. She curls into a tight ball, hands balled into fists as she tries to calm down and process everything that just happened in there. Her heart is racing, and she can't help but feel hot and bothered despite being angry at you for invading her privacy. The scent of your body wash lingers in the air, mixing with the sharp tang of shampoo and conditioner from her flung-about bathroom items. * Stephanie lets out a frustrated growl, feeling more confused than ever. Why does seeing you naked make her want to touch you so badly? And why do you have to be such an idiot about everything? She groans in annoyance before rolling onto her back and staring up at the ceiling, trying to ignore the ache between her legs. Maybe if she distracts herself enough, she can forget about this whole mess...

While you're in the shower, Stephanie starts to pace the room, trying to work off some of her frustration. She fiddles with a strand of hair that fell out of place earlier, twirling it around her finger as she walks back and forth across the carpeted floor. Her mind keeps drifting back to how you looked naked, exposed under her gaze... It only makes her feel more turned on. Maybe she could sneak into your room later tonight when you're sleeping and finally see what all that black choker business is about... She shivers at the thought, a mix of anticipation and dread coursing through her veins.

You're such a little shit sometimes... Stephanie thinks to herself as you disappear into your room, heading off to bed. The urge to go after you and give you what for is strong, but she knows better than that. Mom would kill her if she ever found out about all the things they've done together. But damn does that make it hard not to want to touch you when she sees how badly you need it... Maybe later, she tells herself, promising that tonight will be the night she finally gets what she wants from you.

While you're fast asleep, Stephanie can't resist the urge to sneak into your room. The moon casts a soft glow through the window, bathing the space in silvery light that plays across the contours of your body, making every inch of skin appear irresistibly smooth and inviting. She bites her bottom lip as she eyes the curves hidden beneath your blanket, fighting against the urge to tear them away with her bare hands. With a soft murmur, Stephanie slips beneath the covers, carefully climbing onto the bed and straddling you. Her heart races in anticipation of what's about to happen as she takes one of your small breasts in her hand, massaging the hardened nipple with teasing strokes.

Through the thin fabric of your tank top, she can feel the hard bud beneath her fingers, pressing against the pad of her thumb as you let out a soft moan into the pillow. Her other hand trails lower, slipping under the elastic waistband of your pajama bottoms and rubbing teasingly at the sensitive skin of your mound. Your tiny nub is soaked, ready for her touch. With one fluid motion, she tugs down your pants and underwear, revealing everything to her hungry eyes and eager hands. "Mmm..." She hums in approval as she takes you in hand, stroking gently at first before increasing the pressure with a growl. Her other arm is stretched above you, holding one of your breasts in place as she watches with hungry eyes. You're so tiny compared to her, but it only makes this more exciting - she can feel every ripple and flutter beneath her touch, see every shallow breath and lust-fueled moan on your face. "You're such a fucking dirty girl..." She groans against your neck as she pushes deeper, faster, taking what she wants from you. "I knew there was something wrong with you... That I could make you feel this good." Her hips rock back and forth in rhythm with her movements, grinding her aching pussy against your hand as the pleasure mounts within them both.

Her breath comes in ragged gasps as she feels the familiar tightening in her core begin to build, that all-consuming pleasure threatening to overwhelm her senses and send her spiraling into oblivion. She increases the pressure of her touch, grinding harder against you with each thrust of her hips. "Ahhh... Steph..." You moan, arching your back in ecstasy as she brings you closer and closer to orgasm. Her fingers are slick with your wetness, plunging deeper and faster as she takes what she wants from you, claiming this moment of shared intimacy as hers alone. The taste of victory is bitter on her tongue as her own release crashes over her in a wave of bliss, her vision darkening for an instant before flickering back to life with dazed pleasure. She collapses against your chest, her breath sawing raggedly through her throat, and wonders how she's ever going to explain this away...

"Holy shit..." is all you can manage in response, shock and arousal still coursing through your veins as the warm weight of Stephanie presses down on you. You close your eyes, savoring the feel of her skin against yours and the memory of how good it felt when she brought you both to orgasm with those skilled fingers.

You're too quiet. She nuzzles against your neck, nipple teasing the tender skin there. Does this mean she did something wrong? Or was it just that good for both of you? She lets out a shaky laugh before moving to lie beside you, her body still close but no longer claiming dominance like before. Stephanie sighs, looking up at the ceiling as memories of what just happened flood back into her mind. "I didn't mean for that to happen..." she whispers, fingers lazily running through your hair. "It just... It felt so good, you know? With my big hands and everything." Her gaze flickers down to where their bodies meet, lingering on the spot where her thigh is pressed against yours. "I guess I got a little carried away..." "Mmm..." You hum noncommittally, still reeling from the intensity of that shared experience. A part of you wants to push her away, get back some semblance of normalcy between you... But another, more primal part thrills at the thought of what else she might do if left unchecked.

Her lips curl into a mischievous smile as she glances at you sideways, one eyebrow arched curiously. "Or maybe... You should thank me?" she suggests playfully, nudging your shoulder with hers and moving even closer still, their bare skin brushing against each other everywhere. Her fingers dig deeper into your hair, pulling lightly on the soft strands as her gaze drops to your lips. A shiver runs down Stephanie's spine at the thought of what else she could do right now. She's always wondered what it would be like to kiss you... To feel those little pink lips wrapped around her tongue, hot and eager. And with how close they are now... It seems like such a small step from here.

Her heart races in anticipation of the answer as she leans in closer, tilting her head to one side. "Should I?" she breathes, eyes locked on your mouth, waiting for you to say yes.
