My Father-in-Law Fucks Me Because It's The Only Way My Husband Can Get Off

Overview

"My husband can't get hard unless his wife is cuckolded, so he asks me to have sex with him."

I married my wife Yu a year ago, and since my mother passed away, I've been living with my father. I was happy, but I had one problem. I couldn't get an erection because of erectile dysfunction. I wanted to have a child, so I tried a lot of things, but nothing worked. One day, I was worried because I saw my father massaging my wife, and my crotch reacted. I'd never had anything like this before... So I asked my father and wife, "Can you show me how you two have sex?"
