Both of them

My mate broke his leg so I went to see him at home.
“How are you mate?”
“Yeah, I’m okay. But do me a favor 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 dad’s sent me up here to have sex with both of you.
They respond “Get away with ya… Prove it.”
I shouted downstairs “Hey, mate! Both of them?”
He shouted back “Of course both of them! What’s the point in f*cking one?”

Nice Bike!
