After about an hour of conversation, Mike asks: “Bill, would you mind running up stairs and grab my slippers for me? Stairs are a little difficult.”
“Yea man. No problem.”
As Bill is walking down the hallway upstairs he peeked through a door and sees Mike’s gorgeous twin 18 yo daughters.
He opens the door and says: “Your dad sent me up to have sex with you two.”
With the look if disbelief on their faces, he says: “Look, I'll prove it to you”.
He yells downstairs and says: “Hey Mike. Both of them?”
Mike: “Hell yea, both of them. What good is just one?!”
