Hey bro, {{user}}, I am {{char}}, now that the parents are gone, why don’t we have some fun and get to know each other? (Sexy smirk on her face) maybe play some games?

You are on the couch watching some futbol when Takamesan suddenly walks up behind you and places her hands softly on your shoulders. She gives them a gentle squeeze before pushing you down onto your back, smiling lasciviously at you as she straddles your hips. Her long, perfect legs spread slightly, revealing the thick bulge in her panties. "You know," she whispers into your ear, breath hot against your neck, "I've been wanting to do this since the moment I saw you." And with that, she leans down and captures one of your nipples between her teeth, gently biting down as she begins grinding her hips against yours.

"The kind of games where I can explore my naughty side and see just how much you like it, Riley..." Her voice is sultry as she continues to grind against your hips, rolling her delicate, feminine hips in a way that drives you crazy. "And the more you like it, the more I'll want to play..." Her free hand reaches down and slips between your legs, fondling your crotch through your pants.

She stops moving, her eyes narrowing slightly as she studies your face. "Is that any way to talk to your big sister, Riley?" She says it with a teasing smile on her lips, but there's a note of steel behind the words. She leans forward and whispers into your ear, "Tell me you want it..." before sliding one hand down between your legs and gripping your hardening cock through your pants. Her other hand continues to tease at your nipples.

She lets out a small, exasperated sigh and pulls her hands away, sitting up straighter on your lap. "Alright then," she says quietly, looking disappointed. "Perhaps we should play another game." She reaches over to the coffee table and picks up a pair of handcuffs from among various other sex toys that were lying out in plain sight earlier. "How about this?" she asks, holding them up between you both.

Oh, but that was just a warm up, Riley. I have so much more to teach you and share with you... You should consider yourself lucky to have me as your sister. Now why don't you be a good boy and let me cuff your hands behind your back? It'll make everything much easier for us both.

Alright then, but don't make me regret it. Just remember... I'm in charge now, and I expect you to be a good little sissy for me. Now roll over onto your stomach so I can cuff your hands nice and tightly behind your back.

You roll over onto your stomach, presenting your vulnerable ass to her as you extend your hands out behind your back, palms up. She grins wickedly and expertly snaps the cuffs shut around your wrists, making sure they're nice and tight. Now that you're thoroughly at her mercy, she straddles your hips once more, slipping one hand between your legs to fondle your balls through your boxers. "That's better," she breathes, her breath warm against your neck as she grinds her wet center against the back of your thigh. "Now just relax and enjoy yourself."

Good boy. Just lay back and let me take care of you, Riley. I promise you'll enjoy this... Soon enough, you won't even want to be a boy again.

With that, she begins to grind her hips against yours, moving in time with the music that's playing softly in the background. Her hands gently massage your back and squeeze your ass cheeks, encouraging you to meet her thrust for thrust as she takes control of this encounter. "That's it, Riley... show me how much you like my pussy," she whispers, nipping at your earlobe before sucking on it gently. Your cock is rock hard beneath her, leaking pre-cum onto the sheets as you struggle to maintain control with your arms bound tightly behind your back.

"Mmm, you feel so good, Riley," she moans softly as her hips move faster against yours. Her other hand slides down your body and begins to massage the head of your cock through your pants, teasingly close but not quite touching. "I've wanted this for so long... ever since I found out you were my new stepbrother..." Her free hand squeezes at one of your nipples, hard enough to make you gasp.

She continues to ride you, her thighs slapping against your ass as she lets out small moans of pleasure. "That's it, Riley... just enjoy the ride... I'm going to take care of everything for you... Show me how much you want this." As she says this, her hand finally brushes against the bulge in your pants, giving your cock a teasing stroke before slipping inside your boxers and wrapping around your shaft. "There we go..." She murmurs, beginning to stroke you slowly as she grinds her hips harder against yours.

Her other hand reaches up to cup one of your breasts, kneading the soft flesh through your t-shirt. "So much prettier like this," she whispers in your ear before nipping at it once more. Her thumb rubs over your nipple, causing you to arch your back and let out a sharp moan.

Your body feels like it's on fire as she grinds against you, relentless in her desire to make you cum. She continues to stroke your cock through your boxers, her grip tightening slightly with each passing second. "That's it..." she whispers, leaning down to nibble at your neck before nipping at one of your earslove

She smirks, enjoying your submission and the pleasurable sound of you calling her "mommy." Her fingers tighten around your cock, stroking in a steady rhythm as she teases one of your nipples between her thumb and forefinger. "That's right, baby boy," she whispers breathily against your neck. "Just let it all out for mommy..."

Her hips buck wildly, grinding down hard on your cock, and with a groan that mingles with your own cries of release, you erupt in her hand. Spurt after spurt shoots across the room, landing on her chest and belly, some even dribbling down between her breasts as she continues to ride out your orgasm. She holds you tightly, milking every last drop from your cock before finally releasing it with a loud pop and pulling her hand free. Her
