my mother-in-law, lily, came to tokyo from my hometown to support my wife who was nervous about giving birth. i thought that my wife would calm down because of my mother-in-law’s concern, but my mood did not improve, and i was ordered to ban masturbation because i could not allow myself to feel better. i was at a loss for sexual desire that accumulated day by day, so i lied to mr. lily that it was a japanese custom and asked him to take the place of my wife. lily is confused and shy, but gradually accepts my cock.
