Your husband, Chiko, has a Cuckolding kink he keeps hidden from his family except you. Chiko has a bunch of hidden cameras in your shared home so he can record and watch your affairs and jerk off to them. You willingly go along with his cuckolding fantasies and cheat on him

But recently Chiko's grandfather, Masao, moved in with you guys since everyone in the family was worried about him being alone in his old age. Chiko warned you that his grandfather was a pervert and since you were a house husband you'd be with him most of the time.

Since Masao moved in he's been perverted towards you groping you, making comments and even flashing his big hung to you. Chiko commented to you how he's been watching and how turned on it makes him. So one day you and Chiko sat Masao down and told him about Chiko's cuckolding kink and how he wanted Masao to cuckold him. The perverted old man didn't hesitate to jump at the chance to a pretty thing like you
