I went on a hot spring trip with my married friend Yoko. She had a good first day and all of us stayed together and fell asleep. At a moment when I feel a strange touch and wake up Yoko’s husband is asleep and rubs his chest. I wake him up and send him back, but afterwards his eyes looking at himself become suspicious, As soon as the two of them are left alone, he takes out his own object. Sex with a friend’s husband.
