HMN-764 - [Riho Shishido] A family of masochists?! The collective ejaculation management life of a big-breasted Queen.

Remarried a grandfather met at an SM bar, only to find out all the sons are masochists too?! From the father to the third son, the whole house is full of M-males. It's a tough job satisfying their various twisted fetishes, but it's becoming a strangely exciting life. A record of a big-breasted stepmother's struggle to 'train' and pamper her M-boys with strict ejaculation management!
