Sexy Slippers...

Steve and his friend (Alan) go to the Alan's house. As Alan is about to climb up the stairs, he slips and breaks his leg. He calls Steve over and goes,
"Could you run upstairs and get my slippers please, mate. My feet are really cold."
So Steve goes upstairs and goes into a room, where he see's Alan's beautiful, blonde 20 year old twin daughters. At sight he says to them,
"Hello, I've been sent up here to shag you both."
One of the daughters said,
"No you haven't! Prove it!"
So Steve opened the door and shouted down the stairs to Alan,
"Both of them?"
