My Stepsister and I Caress each other after a Family Party

After the family party, the atmosphere is still charged and passionate. My stepsister, a sultry brunette, and I can't help but feel the spark between us. We're both tipsy and feeling frisky, so we decide to sneak off to my room for some private time. The room is dimly lit, the air thick with anticipation. She's wearing a tight leather jacket that hugs her curves perfectly, and her long legs are encased in a short skirt. I'm wearing a casual look, but there's nothing casual about the way she's looking at me. We start with a simple caress, our hands exploring each other's bodies, our breaths growing heavier. The leather jacket is a fetish for her, and she loves the way it feels against her skin. She pulls it off slowly, revealing her tight top and skirt. I can't help but run my hands over her curves, feeling the softness of her skin. She leans in for a kiss, her tongue invading my mouth, our bodies pressing against each other. She starts to grind against me, and I can feel her heat through her clothes. I reach down and cup her ass, pulling her closer. She moans softly, her hands going to my belt. She unbuckles it, her fingers brushing against my growing erection. She pulls my pants down, revealing my hard cock. She starts to stroke it, her hand wrapping around the shaft. I can feel the heat of her pussy through her skirt, and I can't resist the urge to pull it up and slide my fingers inside her. She gasps, her eyes widening as I begin to finger her. She's so wet, so ready for me. She starts to grind against my hand, her body moving in rhythm with my fingers. I can feel her orgasm building, her body tensing as she gets closer. She comes with a soft cry, her body shaking as waves of pleasure wash over her. She pulls me close, her mouth finding mine in a passionate kiss. I can taste her orgasm on her lips, and it drives me wild. I push her down onto the bed, my cock poised at her entrance. She looks up at me, her eyes filled with desire. I slide inside her, feeling her heat envelop me. She moans, her body arching as I begin to move. I can feel every inch of her, every curve, every pulse. She wraps her legs around me, pulling me deeper. I can feel her orgasm building again, her body tensing as she gets closer. I fuck her harder, faster, my body slamming into hers. She comes again, her body convulsing as she cries out my name. I can't hold back any longer, and I come with a groan, my body shaking as I fill her with my seed. We collapse onto the bed, our bodies slick with sweat, our breaths coming in ragged gasps. We lie there for a moment, our bodies entwined, our hearts beating in sync. It's been a wild night, but we're both satisfied and content. We know this is something we'll never forget, something that will always be ours.
