Stepdaughter

Me, wife and stepdaughter went to a friends place and had some drinks. I got too drunk and passed out in a spare room.
I woke to screaming yelling and wife and step daughter fighting. Apparently stepdaughter caught wife fucking my friend. I said they can have each other and we left her there. My stepdaughter took me the her place and I said I was going to fuck someone too then went to bed.
My stepdaughter came in the room and said, if I fuck you will you forgive my mom? I said yes. She sucked my cock, I ate her out then fucked her all night. We fucked again a few weeks later.
