A married couple returns to the wife's parents' home for the first time in a while. Her parents warmly welcome them, but during a family gathering, when the father-in-law mentions wanting to see a grandchild, the wife suddenly becomes upset and leaves the room. To her parents' surprise, she reveals she's been refusing her husband sexually and won't respond to advances. Seeing their disappointment, he feels guilty. Late at night, as he heads to the bathroom, he notices a light coming from his in-laws' bedroom and quietly peeks inside—only to see them having sex. Though he knows he shouldn't watch, his sexually starved body can't look away. Unable to calm his erection, he begins masturbating in secret—until his mother-in-law catches him. Panicking, he tries to hide, but she says, "Wait," explaining that with her daughter absent, she gets pent up, and if he's okay with it, she'd be willing. Starved for touch, he quickly becomes aroused, but her expert, lingering handjob and blowjob tease him mercilessly, denying release. Just as he's on the verge of exploding, she takes his climax into her mouth. The next day, the father-in-law and wife go out to a nearby izakaya. Awkward after the previous night, the mother-in-law seems uneasy. As night deepens and they don't return, he gathers his courage and heads to her bedroom. Gently lifting the covers, he begins caressing her as she lies asleep. Soon, he hears wet sounds—her pussy starting to respond. Overcome with desire, he can't resist and thrusts inside her, nearly assaulting her in his need.
