The daughter-in-law has an irresistible firm butt, and the father-in-law sexually harasses her while the son is away. The frustrated daughter-in-law gives an awkward response, but the strong-willed daughter-in-law doesn't do what the father-in-law wants, so he asks his friend, a masseuse, to give him an erotic massage between the legs. The daughter-in-law feels so much that she can't resist and gets his cock shoved inside her. The father-in-law uses this as an excuse to have sex with his daughter-in-law without his son knowing.
