My wife wants a child and keeps asking me for sex, but I can't get in the mood. The reason? I have strong feelings for my mother-in-law, Hitomi, who lives with us. She has a better body than my wife, and her sensual presence under the same roof drives me wild. Just thinking about her makes it impossible to be intimate with my wife, and I suffer in silence every day. But one day, I finally take action. I ask my mother-in-law, "Mom, can you take a look at my cock?" Shocked by my unexpected request, Hitomi is flustered. The atmosphere between us instantly changes.
