Even though my pregnant wife has reached a stable stage, she suddenly tells me that she's going on a trip with a friend for 2 nights and 3 days, and I reluctantly send her off... During that time, my girlfriend's mother-in-law, Rieko, took care of me. As I watched her emit her strange sex appeal without realizing it, she became extremely horny, and while we were alone together, I found myself celibate all the time... When Rieko found out about her situation, instead of getting angry, she said, ``Do it.''
