Lately, Emi and I have been arguing a lot. My wife's father took this opportunity to help us reconcile and also wants us to have a grandchild for him, so he organized a trip to a hot spring with the whole family. He made me abstain from that for a month, and today is the day. Speaking of my wife's father, he is also old so his physical condition is not that great. My mother-in-law, on the other hand, is very young and has high needs, but my father-in-law always refuses her advances. After abstaining for over a month, I can hardly bear it anymore. I want to make love with my wife, but she refuses, no matter how much I beg. While wandering around the house, I accidentally witnessed my mother-in-law taking a shower, and her extremely seductive body made me lose control...
