KIR-020 A son-in-law who sneaks away from the eyes of his mother-in-law, a forty-something woman overflowing with sensual allure, to pursue the body of a mature woman. Shiokawa Kana.

My wife was hospitalized for her first childbirth. For the next few days, it's just me and my mother-in-law… I've been holding back from having sex with my wife, so I can't stand it anymore… My mother-in-law doesn't look like she's in her forties, but despite her slim figure, all the right parts are in the right places, making her very sexy… I want to do something about my mother-in-law's lewd body!! 'Are you really going to have sex? You can never tell our daughter about this.'
