I'm a 23 year old, straight white guy; I've been with my girlfriend for over a year now and things are great between us. A few months into our relationship, she mentioned that I get my good looks from my dad. That comment caught me off guard and it's grown into this fantasy of my girlfriend having sex with my dad. I can't stop thinking about it. I get my hardest erections when I think of them fucking.

My parents are happily married, but I wonder if he would take the chance with my girlfriend.
