A man goes to a disco and starts chatting up a very attractive looking Chinese girl.

She appears to be all over him and soon asks him back to her place "for a coffee". 

When they get to her flat she tells him to help himself to a drink while she slips into something more comfortable....

Just as he finishes getting the drink the sexy Chinese seductress returns wearing only a see-through negligee.

"I am your sex slave!" she says, "I will do absolutely ANYTHING you want"

Well the man is taken a little bit by surprise and can't believe his luck so he says: "I really fancy a 69"
