My daughter Yuri is full of energy, and my wife Rumiko is homely and kind. Blessed with such a wife and children, I was spending very happy days.

But my daily life changed drastically. It was a holiday... I happened to overhear Yuri and Rumiko having a ridiculous conversation.

She said, “You want to do something about the fact that our sex life is in a rut, don't you, Mom?”

She said, “Yeah...I guess so...”

"Then why don't you try anal sex?”

"I'm not too keen on that..."

"Then how about this? I'll have anal sex with dad in front of you, mom."

The conversation went on and on and on. In the end I wound up having sex with Yuri...

I wonder what is going to happen to me...?
