During My Wife's Pregnancy, I Was Forbidden To Even Masturbate, And I Repeatedly Had Sex With My Mother-in-law Yuna, Who Had Come To Tokyo... Yuna Shiina(2023)

During my wife's pregnancy, my mother-in-law Yuna came to Tokyo to support my surroundings. My wife forbade me to smoke and masturbate, so I couldn't take my eyes off the beautiful and attractive Yuna. And one night, the hidden masturbation is found out by his wife and gets into a fight. Yuna-san witnessed it when I sniffed Yuna-san's underwear after my wife went to bed. Yuna didn't even blame me, and reached out to my crotch because I would solve it.
