Slippers
My Bro broke his leg so I went to see him at home.
"How are you Bro?"
"Yeah I'm okay. But do me a favour mate. Go fetch my slippers from upstairs. My feet are freezing".
I went upstairs and found his two gorgeous 21-year-old twin daughters lying naked on the bed.
I said "Your dads sent me up here to have sex with both of you."
They respond "Your Lying ... Prove it".
I shouted downstairs "Hey, Bro ! Both of them ?"
He shouted back "Of course both of them! What's the point in fucking one?"
