By exploiting his voyeur fetish.

"And you sure love this sensation" you say. "Did you ever expect to see a pretty couple like us, walking in in naked ?", you ask him.

"I admit, it's something new for me. But do you really think you can talk yourself out of my office ?", he replies. "People outside were really upset of your behavior.", he explains.

"I'm sure they were, but you are different. I bet you have your reasons to talk with us private.", you argue.

"Go on", he says, smiling somewhat amused.

_"You don't wanna call the cops, you could have done this earlier if you wanted to. So I guess you like what you see.", _you question him.

"Hold on, Lady Godiva! Do you really think I'm into barely legal teens?", he replies to what you're trying to imply.

"I think you're not a pervert, but it's totally normal if you enjoy watching a nude couple sharing some intimate moments. You mentioned you watched what we did under the table, but you didn't say, you find it disgusting, and you never told us to dress up.", you argued decisively.

By the look of his face you can say, you nearly got him where you want. With you heart beating like a hammer within your chest, you keep talking.

"So I thought, we could make a little deal". you begin to speak, "You like what you see and we love to be naked. What about ... a little live show, especially for you and you could forget to call the police, while we dress up and leave.", you offer.

Holding your breath you wait for his answer.

"Damn girl", he says with his fist beating on his desk,_ "you won. But you'll never tell anybody what happens here.", _he responds.

"You can bet" ,you say, while thinking of what naughty things you're going to do in front of him.
