Makoto is married to a younger man and has a higher career and income. Her pathetic son is visited by his father-in-law, who sexually harasses him constantly. Thinking that his son will not be satisfied with his wife, he has his sights set on his sexy wife's body. He uses oil to tease her, gives her an extra thick massage, and gives her an intense fuck, as her pent-up desires explode. Her body is on fire and her brother-in-law makes her cum over and over again with a vigorous piston-like fuck.
