My mother-in-law Yuka comes to help care for my pregnant wife. Her presence eases my wife's frustration, but with masturbation forbidden, I can barely suppress my desire around Yuka's voluptuous body and intoxicating scent. Sensing the awkward tension in our marriage, she comforts me after my wife falls asleep. When she asks me to share whatever is troubling me, I show her my rock-hard bulge and beg her to take care of it just once.
