Returning home to his wife's parents' house after a long time, the couple was warmly welcomed as always. But during a family gathering, when the father-in-law mentioned wanting to see grandchildren, the wife suddenly became upset and left the room. Sensing the parents' confusion, the husband confessed that his wife had been rejecting him sexually, turning him down whenever he made advances. Seeing their disappointment, he felt deeply guilty. Late that night, waking to use the toilet, he noticed a light coming from his in-laws' bedroom. Peeking inside, he caught them having sex. Though he knew he shouldn't watch, his arousal overwhelmed him and he couldn't look away. Unable to calm his erection, he began secretly masturbating—until the mother-in-law appeared. Panicking, he tried to hide, but she told him to wait, saying she gets pent up now that her daughter isn't around. Then, offering herself, she began pleasuring him. Being touched after so long made him quickly aroused, and her skilled handjob and blowjob brought him to the brink without letting him cum—until at the peak of ecstasy, she took his load in her mouth. The next day, the father-in-law and wife went out to a nearby izakaya. Awkward after the previous night, the mother-in-law seemed uneasy. As night deepened and they didn't return, he could no longer restrain himself and went to her room. Gently pulling back the covers, he found her asleep and began caressing her. Soon, wet sounds filled the air as she woke in surprise. Overcome with desire, he thrust into her almost forcefully.
