The rumor that when a girl gives you sex in her room is a sign that it's OK to have sex... it was true. When I missed the last train due to overtime, I asked, ``Senpai, is it okay if I stay with you?'' I lied and went to my junior colleague, Mr. Uno's room, even though my wife was there, but I had some ulterior motives. As soon as I entered the room, I took off my stockings, I could see a glimpse of her breasts, I was seduced by her close contact with me in my loungewear, I had a shy face with no make-up, which was different from the atmosphere at work... The forbidden fruit was so delicious that I fucked her all night, even though I knew it was cheating.
