He meets his ex-girlfriend for the first time in two years. They are both married now, but he can't forget the exciting sex they had back then that he can't have with his current partner, so they have a one-day affair. "You're married, right?" He is so excited that he thinks Mizuki has become someone else's wife. He reveals his sexual tendencies, has perverted sex, and cums inside her many times. Because she is his ex-girlfriend, it feels even better. Deep throating, exchanging saliva, licking anal, peeing, swallowing, cumming inside...sex where a man and a woman just instinctively interact.
