一天我去朋友老張家探望他，看到他膝蓋痛而躺在沙發上休息。
我們聊了一下後，老張對我說：
「你可以去樓上幫我拿雙襪子嗎？我腳好冷。」
我走上樓，看見老張的雙胞胎女兒全裸躺在床上，於是我對她們說：
「你們爸爸要我上來幹你們。」
兩個女兒一臉不信的說：
「怎麼可能，證明給我們看。」
於是我對樓下喊道：
「老張！兩個都要嗎？」
老張回：
「廢話！一個哪夠！」

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 favour mate. Go fetchmy slippers from upstairs. My f
eet are freezing."
I went upstairs and found his two gorgeous 21 year old twin daughters lying nake
d on the bed.
I said "Your dad's sent me up here to have sex with both of you.
They respond "Get away with you... Prove it."
I shouted downstairs "Hey, mate! Both of them?"
He shouted back "Of course both of them! What's the point in fucking one?"
