Explain your situation.

You frantically explain to him what happened, at least vaguely. You say that you made a bet with a friend and you ask him to ignore you.

"Damn. That's one kinky bet you made," he replies. "You're willingly walking around in here without a top, eh? And you're hot as hell."

Stepping up from the wall, you continue to cover yourself, and hope you can skirt around the stranger to make a break for it. He's in the way of continuing forward after all. Though it's hard to focus, feeling so exposed in front of him. There's not much you can do.

He approached you slowly. "Hey. I can help you get to the end. We can go together, eh?"

You take a step back, and remove one arm from your breasts (keeping the other there to cover up of course), and gesture for him to stay back. But he immediately grabs that hand, and holds it tight. It seems as if he misunderstood you.

"You accept? Let's go then!" With a smirk, he laughs, and gives you a tug. It makes it difficult to keep covering yourself up!

Quickly, you explain that you want to find the exit alone given your embarrassing situation.
