JUQ-199 Sneaking around with his mother-in-law behind his wife's back

Yuka's mother-in-law came to take care of her pregnant wife. Arika-san's visit relieved my wife's frustration, but since I was forbidden to masturbate, all I could do was suppress my lust for Arika's attractive body and intoxicating scent- san. Mr. Arika, who sensed the awkwardness of such a couple, comforted me after my wife went to bed. I was told to say if I was in any trouble, so I showed Gingin my swollen groin and asked Arika to serve me just once.
