My stepsister and I were stuck in the closet, hiding from our parents. Space was tight, but our hormones were raging. She backed onto me, pressing her luscious ass against my crotch. I couldn't help but get hard. She felt it, and to my surprise, she grinded against it. I unzipped, freeing my throbbing cock. She looked back, then reached behind to guide me in. I slid into her wetness, her tightness enveloping me. We fucked silently, our bodies moving in sync, her juices coating my cock. I couldn't hold back, and she came with me, my cum filling her, leaking out as we finally pulled apart.
