My mother-in-law, Ayaka, lives with us to support my wife who is in the late stages of pregnancy. Ayaka mediates between us and my unstable wife, but I've reached my limit due to her order to not masturbate. Then one day, I lost my sense of reason when I saw Ayaka's bra in the dressing room and she saw me sniffing it. However, instead of getting angry, Ayaka sympathized with me and gently reached out her hand to my crotch, saying that it was okay if I was her.
