Des:Kana, my mother-in-law, came to Tokyo half a month ago to support my pregnant wife. I thought that thanks to my girlfriend Kana-san, her housework would be easier and her wife would be in a better mood, but she was more arrogant than before, and even more so, she became furious at me for comforting her alone. She is given a ban on masturbation. A few days later, she said that Kana-san, who had heard our argument, was going to take her place, saying that she was in agony because she couldnt control her sexual desire. I was on the verge of overflowing with sexual desire for her, so I made the excuse that it would only be once and asked for Kana.
