A timid young wife runs a beauty salon from home, using her professional experience while enjoying an apparently comfortable marriage with her gentle husband—until a vile neighbor arrives with a trap. During treatment, he exposes his throbbing erection and notices how wet she gets while staring at his thick cock. Exploiting his position as a customer, he turns the session into a predatory erotic oil massage, orders her to work lower, and pressures her to admit she is sexually frustrated and beg him to shove it inside.
