一天我去朋友老张家探望他，看到他膝盖痛而躺在沙发上休息。
我们聊了一下后，老张对我说：
“你可以去楼上帮我拿双袜子吗？我脚好冷。”
我走上楼，看见老张的双胞胎女儿全裸躺在床上，于是我对她们说：
“你们爸爸要我上来干你们。”
两个女儿一脸不信的说：
“怎么可能，证明给我们看。”
于是我对楼下喊道：
“老张！两个都要吗？”
老张回：
“废话！一个哪够！”

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?"
