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