In a dimly lit room, a faceless figure bends over, offering up their plump, round ass. A thick, hard cock presses against the entrance, teasing, before sliding in with a smooth, lubricated glide. The unknown assailant grips the hips, pounding in and out, the sound of flesh slapping against flesh filling the room. The recipient moans, pushed into the bed, their ass getting stretched and filled. Finally, with a grunt, the anonymous cock pulls out, painting the red, used ass with hot, sticky cum.
