Eva Slim, my sexy step-sister, and I sneak into our empty gym room, our hearts pounding with anticipation. The scent of sweat and sex fills the air as we lock the door behind us. Eva, a raven-haired teen with a tight, shaved pussy, wastes no time, dropping to her knees and unleashing my throbbing cock. She takes it deep, her big brown eyes looking up at me as she expertly works my shaft with her tongue. I return the favor, feasting on her wet cunt before bending her over the weight bench and slamming into her from behind. Our bodies slap together, the sound echoing in the room as we fuck hard and fast. Eva's moans grow louder, her pussy clenching around my cock as she nears orgasm. I pull out, painting her face with my hot cum as she eagerly opens her mouth to taste her own juices.
