Have sex with your parents.

"...to fuck your parents," Sophia says.

Your shocked. You never even imagined your parents having sex let alone them having sex with your girlfriend involved. You take a deep breath and tell Sophia, "Ok, I did say anything, but don't you think that's a little extreme?"

"Of course it is! That's exactly what makes it my darkest and dirtiest desire," Sophia says. "This is not something I would've ever imagined actually doing but you gave me the chance."

"Ok," you respond. "This will be an awkward conversation but I'll talk to them. We'll see what they have to say."

Over the week you keep fighting with yourself internally on how you will bring this up to your parents. It's not like they'd normally want to fuck their daughter-in-law...right? You promised your girlfriend to do it but will you really?
