A therapist who rubs her crotch against paper panties amidst the confusion of treatment. Further, with a superb technique, she gradually removes the paper panties of an aroused male client by wriggling her hips, and then presses his protruding glans against her crotch, inserting it with the panties still on. The male client, continuing to expose his defenseless lower body to such lewd acts of the therapist, reaches his limit of endurance and releases a large amount of sperm. Seeing this, the therapist's reason collapses, and she enters into forbidden full-on sexual activity at the shop. This time, she finds herself in the position of being taken advantage of.
