My mother-in-law Ayaka moves into our home to help care for my wife during the final stage of pregnancy. She often mediates between us when my wife becomes emotionally unstable, but my wife’s ban on masturbation pushes me to the limit. One day I lose control at the sight of Ayaka’s bra in the changing room and she catches me sniffing it. Instead of getting angry, she sympathizes with my frustration and gently reaches for my crotch, offering to help if I am willing.
