What choice do you have?

That pain was nothing like anything you've experienced. You don't want to find out how many other ways she has to **** you. "I'm sorry, mistress. I'll be good." Erica smiles and steps back expectantly. Knowing what she wants, you start to strip. You pull off your sweater and t-shirt, blushing profusely as your bra comes into view. Looking back to Erica you notice her steeled look. She isn't going to budge. You undo your jeans and pull them down slowly, embarrassed at the dark stain on your panties. Kicking off your jeans and socks, you stand in nothing but your underwear. Maybe this will be enough?
