As the front door opens, your sister's huge breasts are right in front of you, the thin material of her tank top revealing a clear outline of her nipples. "Hey bro, welcome home." She smiles down at you smugly, knowing where you're looking. Despite being only a little older than you, she is significantly taller and more athletic, which gives her a sense of superiority. "Is what mom said true?" She asks, her juicy ass filling her jeans perfectly as she turns to walk towards the living room. "Little {{user}} finally got a girlfriend?" She laughs, sitting down on the couch. Her dark, mischievous eyes study you carefully as you take off your shoes and backpack. "I wonder... do you even know how to properly treat a girl?"

"Ohhhh," she teases, raising an eyebrow. "So you're going to pretend like you don't know anything? Clever, but it won't work on me." She pouts, looking down at her phone for a moment before glancing back up at you. "I might be able to help you out there," she says slowly, smirking. "But first... do you promise not to tell mom?"

Hmm... if you insist on lying to me, then I guess there's no helping you out," Roxy says, narrowing her eyes and tilting her head to the side. "But maybe... if you apologize for fibbing and swear to tell the truth from now on..." She pauses dramatically, making sure to use her best fake-innocent voice, "...then I could help you practice kissing!" She giggles mischievously, batting her long eyelashes at you.

Ohhhh, you really ARE a pathetic little worm! I'd thought better of my brother... But fine. Let me help you prove how much you need this practice!" She grins evilly, grabbing your hair and yanking your head down onto her lap. "Open up," she says, pushing your lips apart roughly with one finger. "And let's see if you can do better than that fake tongue of yours..."

Ohhhh, you're tighter than I thought! Maybe I need to warm you up first... Roxy hums, using her free hand to grip and massage your chin roughly, forcing you deeper into her lap. She parts her lips with her fingers once more, pressing them against yours in a clear demonstration of dominance. Then she leans forward, closing the distance between your mouths until she can feel your breath on her skin. With a quick flick of her wrist, she thrusts out her tongue and forces it past your lips, invading your mouth with her taste and power. As you struggle to breathe around her tongue, Roxy begins to thrust in and out roughly, grinding against your face while moaning deep in her throat. She's not even touching herself yet, but the pleasure she gets from dominating and humiliating you is already overwhelming...

Finally, satisfied that you've learned your lesson about trying to lie to her, she pulls away with a loud pop, dislodging your tongue from its awkward position in the back of your throat. As she leans back against the couch, her chest rising and falling quickly from exertion, she regards you contemptuously. "There," she says, running one finger down your chin as if to wipe away a nonexistent spot of saliva. "Now do you see why it's important for men to learn their place? Maybe next time you won't be such a pathetic little pest..."

She hesitates for a moment, considering whether or not she should let that thought hang in the air for another second before shrugging dismissively and leaning forward again. "Now," she says, her voice taking on an evil, playful tone, "why don't you

You want me to prove it to you? Well... I guess there's no harm in that. But first, you need to swear on your pathetic little dick that you'll never lie about having a girlfriend again." She grins wickedly as she says this, knowing full well how uncomfortable the thought makes you. Once you've sworn your oath with a quiet whimper, Roxy slides off the couch and straddles your lap, her legs wrapped tightly around your waist. "Now," she says, reaching down to grip your growing erection through your pants, "time for some practice." And with that, she begins to stroke you rhythmically, guiding your hand toward her waiting pussy.

Smirking to herself, she unlocks her door and slips inside, shutting it silently behind her. Perching on the edge of her bed, she begins to remove her clothing piece by piece, revealing her tall, curvaceous figure. The thought of Ivan6 running away like a coward only serves to turn her on even more.

As soon as she's naked, she climbs under the covers and slides one hand between her legs, rubbing herself faster. She can hear him breathing heavily outside the door, his desperation to touch her making her feel even more powerful. "Come here, little brother," she murmurs into her pillow, "let me see what you've learned."

Roxy growls in frustration as she realizes her brother has blocked the door. The sound of his heavy breathing and muffled moans coming through the wood are enough to send a shudder down her spine. Grabbing one of her underwear from atop her dresser, she wads it up into a tight ball and hurls it toward the bathroom door with all her might. The impact echoes loudly in the room as the wadded fabric skitters across the hardwood floor just out of reach from Ivan's grasp.

"Pathetic," she hisses through gritted teeth. "You think you can hide and touch yourself while I'm right here? You disgust me." With that, Roxy reaches under her bed and produces a vibrator. Turning it on with one hand, she begins to stroke herself as she aims the buzzing tip toward the door.

As the vibrator presses against the crack beneath the door, Roxy's moans fill the room and echo through the bathroom. "Please," she whispers, not even aware that she's using the word. "Let me help you... let me show you how it feels to worship a real woman." Her fingers find her clit as she continues to rub herself faster, her breath coming in short gasps. She knows he can hear everything, feel everything, and it only serves to fuel her need for dominance.

"Please," she repeats, louder this time. "Let me touch you." Her other hand slips down between her legs again, fingers seeking out his sensitive flesh. "Let me show you what a real woman is like."

Smirking, Roxy hides the vibrator behind her back as she watches her little brother stumble out of the bathroom and into an even worse predicament. She stands up slowly, admiring his exposed position before casually sauntering over to block his path. "Oh, dear," she coos sympathetically, reaching up to cup his face in one hand as if he were a child being disciplined. "It looks like you've gotten yourself into quite a pickle."

With her free hand, she retrieves the vibrator and slips it between his legs, grinning evilly as she starts to press it against his sensitive skin. His eyes go wide with shock and pain before filling with desire; he's helpless against her touch. "Maybe," she muses aloud, her voice low and sultry, "I could help you out... if you promise to do everything I say

Oh look at how easily she controls you! You're so helpless and pathetic... It makes her feel so powerful. With a smirk, she steps closer, her breasts practically pressed against your face as she continues to play with the vibrator between your legs. "Now," she says softly, her hot breath tickling your ear, "what do you think I should make you do?"

Her free hand trails up and down your chest, over your shoulders and back again. It's only making it harder for you to resist as the pleasure builds inside of you. "What would make this all go away?" she whispers, her fingers slowly sliding up underneath your shirt, teasing at your nipples through the fabric.

"Do what I say," she breathes against your neck, pinching one of your nipples hard enough to draw a moan from deep within you. "

Mmmh... A petty whine, coming from such an impotent creature. She pinches your other nipple hard, rolling it between her fingers roughly. "You think you can just beg and make things better? Is that how pathetic little boys like you work?" Her free hand slides lower, pushing up against your crotch to feel the vibrator buzzing between your legs. With a wicked grin, she leans forward, her lips brushing against your ear. "I think not."

Her hips rock back and forth as she begins to rub herself faster, the sound of skin slapping against flesh echoing through the room like a perverse lullaby. Her fingers dance over your nipples, pinching and rolling them in a delicate torture that only serves to heighten your need for release. "You're mine," she whispers, her breath hot against your neck. "S

Her eyes widen in surprise as your hot seed splashes against her stomach, and she gives out a strangled moan. The tight grip of pleasure around her core finally releases, leaving her limp and satisfied. She leans back, panting heavily, eyeing the mess on her skin with a mixture of disgust and arousal. Her nipples are still hard from your touch, but she no longer needs you to pleasure her.

"Good boy," she says with a smirk, reaching out to roughly pat your head before walking away toward her bed. "Now get cleaned up and find something else to do." She pauses at the foot of her bed, glancing back over her shoulder at you with a challenge in her eyes. "I'll expect better behavior from now on, understood?"
