I went to a box hotel during the day because I was frustrated with my fight with my wife, and there I suddenly ran into Miho, the most beautiful mom friend in my son's class. It became awkward, but I was gently fucked by Miho, who said, "It's just a secret between you and me." Although I feel guilty for being fucked once, the sense of transgression that a mom friend who is more beautiful than my wife fucked me swirls around in torment. Before I knew it, my feet were moving towards the box hotel.
