Azusa Mayumi, a diligent housewife, is very fond of her daughter and son-in-law because they have not yet given her a grandchild to hold. Azusa Mayumi loves and cares for them dearly. One day, while her son-in-law was taking a shower and ran out of shampoo, he called for help from outside. His mother-in-law, holding a bottle of shampoo, knocked on the bathroom door and walked in without a hint of embarrassment. The son-in-law, sitting in the bathtub, covered himself with his hands, feeling shy. That night, he craved intimacy and called for his wife, but she rolled over and fell asleep, which frustrated him as she couldn't meet his needs. He went outside and heard noises from his in-laws' room. When he peered into the room, he saw them making love. After looking for a while, he returned to his room, glanced at his wife, and shook his head in displeasure. The next day, after breakfast, he waited for his wife and father to go to work, and immediately persuaded his mother-in-law to fuck each other, the mother didn't want to, but she still liked it, so she didn't use all her strength to push him out, the two of them fucked each other in pleasure, in the afternoon of the same day, the mother and he sat in the room folding clothes while the wife was outside drying clothes and the father-in-law was in the living room, The 2 people continued to sneak at the beginning with passionate kisses, almost found out, luckily but on high alert when his wife passed by, then the 2 people continued the clumsy affair, fortunately the father-in-law and wife went out at that time, so the 2 people comfortably fucked each other in the house without being detected. It's just because his wife is bad, but he can't even serve his physiology, so he clumsily has an affair with his mother-in-law, otherwise this clumsy love affair will happen everywhere, right?
