When she remarried an older man she met at an SM bar, all of her sons became masochists too. The whole family has become masochists!! Dad, eldest son, second son, third son. Each of them is a complicated masochist, and as a remarried woman, I have to accommodate each of their sexual preferences, which is a difficult but somehow fun and strange life. A record of the struggles of a busty mother who dotes on her masochistic man!!
