A beautiful girl in a uniform intently stares at a middle-aged man's anus. Curious and excited, she starts by licking his anus while giving him a handjob, gradually getting his penis erect. She then carefully inserts fingers and anal beads, teasing the man with playful remarks like "How funny~♪" as the beads spill out from his ass. Next, she puts on a strapon and mounts him doggystyle, thrusting hard and rhythmically, making the man moan involuntarily. Seemingly drawn by the noise, several naked men suddenly burst into the room.
