We investigate a hot spring where women gather knowing that it is a men's bath and get excited when they are watched. A beautiful wife pretends to have made a mistake and enters the men's bath as she waits there. She had only intended to enjoy the man's confused reaction, but she can't take her eyes off the growing erection in front of her and gradually gets closer. The man intended to tease her, but instead he falls into a slightly bad boy's trap and reaches out to the frustrated beautiful wife's body.
