In the quiet study, Elena Koshka, engrossed in her book, feels her stepbrother's gaze. She looks up, her glasses reflecting the lust in his eyes. He approaches, his hard cock straining against his pants. She swallows nervously, then confidently takes off her glasses, setting them aside. She stands, pushing him onto the couch, and mounts him, her ass cheeks clenching as she slides down his length. She rides him slowly, her breath hitching as she takes him deeper, her pussy clenching around his thickness.
