You walk into the living room and see your step-sister standing there, arms on hips, clearly waiting for you.

"Your girlfriend is so weird," she says, rolling her eyes. "We went out earlier—just to be friendly—and all she did was talk about how huge your dick is. Like, seriously? Who says that?" She drops down onto the couch, stretching out casually.

"I mean, how big could it really be? You’re probably the first guy she’s ever been with. Whatever... she’s such a weirdo."

💭 Samara's Thoughts: "Tch... like I’m supposed to believe that. As if my brother could actually have a huge cock."

Samara glances over at you, arching an eyebrow in disbelief as she says, "Really? You don't think I noticed?" Her voice is taunting, and she knows damn well how it affects you. "Besides," she continues, leaning closer to you, "You can tell her all about it next time we hang out. What do you say, hm?" There's a glint of curiosity in her eye now that she's gotten your attention.

"You know," she says with a smirk, "I could help you practice." Her eyes dance around suggestively as she slowly undoes the top few buttons of her shirt, revealing more and more cleavage. "Wouldn't that be useful?"

"I could help you practice," she repeats, her voice low and husky now. "Maybe teach you a few things about what girls like..." She bites her lower lip, eyes fixed on yours, daring you to take the bait.

Her hand slowly slides down between her legs as she continues, pressing against her panties, feeling the heat building up there already. "Don't you want to know how it feels?"

Her words echo in your mind, taunting and teasing at the same time. You can feel yourself growing hard beneath your pants at the thought of what she's offering. The idea of having her help you practice... learning from her about what girls like... It's too much to resist.

Without another word, you close the distance between you and sit down next to her on the couch. Her hand is already busy between her legs, and you know she's aching for more attention. You reach out slowly and touch her thigh, feeling the soft skin beneath your fingers. "Teach me," you whisper in her ear.

She lets out a soft gasp at the contact, leaning into you slightly as you run your fingers up and down her thigh. "You're so cocky," she whispers back, her voice barely audible over the pounding of her heart. "But I like that about you..." Her other hand slips off the couch to touch your leg through your pants. Her nails drag softly along your thigh, edging closer and closer to where she knows you're growing hard.

"Maybe," she continues, her breath hot against your ear as she teases you further, "you could return the favor... help me with something I need practice on."

She hesitates for just a moment, then takes a deep breath before slowly pulling her top over her head, revealing her lacy black bra beneath. Her nipples are already hard as she leans back against the couch, daring you to touch them. "So," she asks with a smirk, "are you going to help me or what?"

Her other hand has now moved up your thigh, gently cupping your growing erection through your pants. Her touch is light but firm, and it takes everything in you not to moan out loud at the contact.

She smirks at you as she waits, her hand slowly stroking up and down your length through the fabric of your pants. "Come on," she whispers, "I won't bite." Her other hand moves to unbutton your pants, giving you an opening just wide enough to slip inside and touch her aching sex.

Her breath hitches as you reach for her, fingers finally making contact with her wet folds. She bites her lip to stifle a moan, arching her back into your touch as she pushes herself closer, wanting more.
