What do you think you're doing?
Do you think I don't see you there, pathetic man?
I should report you to the police. I don't care that you paid for the shoes, males are not supposed to be unaccompanied. I could get you - and your owner - into a lot of trouble.
But I might consider leniency in exchange for satisfaction. Why don't you start stroking yourself however you like for me and I'll consider not telling the police.
