During my wife's pregnancy, my mother-in-law, Naho, came over to help take care of her. Naho was a great cook, had an incredible figure, and was even more beautiful than my wife, so I was often entranced. After a while, I couldn't have sex while my wife was pregnant, and I couldn't masturbate with Naho around, so I finally reached my limit and went to a married woman's brothel... But I unexpectedly encountered Naho, and she licked my mouth with a passionate French kiss, saying, "Don't tell my daughter..." and I lost my reason...
