Adult aspiring idol Himawari Natsuno is practicing her dance routine in front of a mirror when the office doorbell rings during her break. With no one else around, she opens the door—only for an obsessed fan to force his way inside. When a nervous Himawari asks what he wants, he says, “You promised, remember? You said you’d do anything for me,” then drops his pants and thrusts his rock-hard cock at her. There is no staff member around to drag him away today, so what will happen to Himawari?
