While her husband is away on a business trip, her stepson comes to visit. The sex-starved mother gets caught masturbating by her son, but instead of being embarrassed, she takes advantage of the situation and starts playing with his drunkenly passed-out cock. "Isn't it big? Ah, it smells like sweat, it smells so good!" She enjoys his cock with her hands and mouth, saying, "No, don't touch it so much..." and "Mom, I can't help but want to fuck you, please lick my pussy!" Later, the wife is called to her husband's boss's house and learns that her husband owes him three million yen. The boss then demands repayment... "Why did you lend such a large sum to your husband?" "I wanted to be able to do whatever I wanted with your wife someday." Unable to disobey, she opens her pussy and anus, saying, "It's so hot today that my pussy smells like it's steamed." "If you smell it that much, I'll go crazy!" This two-part story features steamy scenes of a mother succumbing to her desires for her stepson.
