Little Stepsister Rides me until I Cum in her Teen Pussy

As I watch my petite stepsister prance around the house, I can't help but feel a stirring in my loins. She's a tiny little thing, with her small tits and petite frame, but she's got a wildfire in her eyes that belies her innocent demeanor. She's always been a bit of a tease, but today, she's pushing her luck. She's wearing her school uniform, a short skirt that barely covers her ass, and a tight top that accentuates her flat stomach and tiny, perky tits.

As I'm sitting on the couch, she struts over to me, her hips swaying with each step. She leans in, her breath hot on my ear as she whispers, "I want you to fuck me, big brother. I want you to make me cum like you've never made me cum before." My heart races as I feel her hand slip inside my pants, her small fingers wrapping around my hard cock. She pulls it out, stroking it gently, her eyes wide with anticipation.

She climbs onto my lap, her skirt riding up to reveal her thick thighs. She grinds against me, her pussy rubbing against my cock through her panties. I can feel her heat, her wetness seeping through the thin fabric. She leans in for a kiss, her tongue exploring my mouth as her hands unbutton my shirt, pushing it off my shoulders. I pull her tight against me, my hands exploring her body, feeling the smooth skin of her back, her small ass, and the curve of her waist.

She breaks the kiss, her breath ragged as she whispers, "I want to ride you, big brother. I want you to fuck me until you cum inside me." Before I can respond, she's pulling down her panties, her pussy bare and glistening with her arousal. She guides my cock to her entrance, her eyes locked with mine as she slowly lowers herself onto me.

She's so tight, so wet, that I can barely control myself as she begins to move. She rides me like a pro, her hips swaying in a rhythm that drives me wild. I can feel her pussy clenching around my cock, her body trembling as she gets closer to her orgasm. She leans back, her tits bouncing as she fucks me harder, faster. I grab her hips, my fingers digging into her soft flesh as I thrust up into her, meeting her stroke for stroke.

Her breathing becomes ragged, her moans filling the room. I can feel her body tensing, her pussy clenching around my cock as she reaches her climax. I can't hold back any longer. With a groan, I thrust into her one last time, my cock pulsing as I cum inside her. She collapses onto me, her body shaking with the aftershocks of her orgasm.

As we catch our breath, she looks up at me, a smile playing on her lips. "You did it, big brother. You made me cum like no one else has ever done." I smile back at her, my heart pounding in my chest. This is one step-sister fantasy that's going to be hard to forget.
