A father lives with his son and his wife. Curious about his young, busty wife, he secretly films their life with a video camera. One day, while his son is away on a business trip, the father-in-law heads to the bedroom where his frustrated wife is masturbating. The father-in-law forces himself on his wife, who tries to stop masturbating and try to cover it up. At first, the wife resists, but her father-in-law's caresses make her feel aroused and she can't resist him and ends up being raped. The wife, captivated by her father-in-law's experienced techniques, takes a bath with him, caressing each other, and the next morning they have sex and cum over and over again, even allowing him to cum inside her.
