I'm a Maso living at my wife's parents' house. Although I'm frustrated with my wife for not letting me, I'm doing my best thanks to my kind mother-in-law. My mother-in-law, Noriko, is a beautiful woman with a plump figure, and I couldn't help but follow her with my eyes. When my father-in-law jokingly told me not to touch her, I thought he found out and was more surprised than usual, but I laughed it off. At night, my mother-in-law went to the bath. I went to the bathroom to sneak a peek at my mother-in-law taking a bath. Then my mother-in-law touched her body and masturbated as if to show me. I couldn't hold it in anymore and opened the door and hugged my mother-in-law. When I told my mother-in-law, who resisted, that I had seen it all and couldn't hold it in, she said that it was just this one time and gave me her mouth and hands. The next day, everyone went out and when my mother-in-law was alone, I returned home. I caressed my surprised mother-in-law over her clothes. Ignoring her resistance, I took off her clothes and touched her crotch, and her underwear was stained with overflowing love juice. I inserted my cock into my mother-in-law, who was reluctant but reacted sensitively. I thrust my cock into her, enjoying her orgasm, and then I ejaculated. When I offered Shizuku dripping meat to her mouth, she sucked my Shizuku with a troubled yet slightly happy look on her face...
