It's not really a choice

You don't really have a choice at this point, and decide that if you should just comply with the blonde. You wait for the attendant to unzip his shorts, since your hands are still bound behind your back. "What are you waiting for? Surely a slut like you knows how to suck a cock." The blonde says, clearly enjoying degrading you.

"I can't unzip him." You reply, hoping to not piss off the blonde even more. The blonde laughs, and the attendant moves to unzip, but is stopped.

"Use your teeth, slut." You wince at that, but set to work on unzipping his shorts. It is much harder than you imagined, especially woth the material being stretched out.

You lose track of how long it's been since he started, but he has brought you to orgasm at least two more times. You faintly feel his cock twitch as he pulls out of you, and you collapse backwards, with a dazed expression and an even more dazed state of mind. You hear the blond laughing, and the attendant groan as he showers you with spurt after spurt of cum. You moan, and lay there in a puddle of your cum while you get covered in his cum. When he finishes, you couldn't be happier. Being used like that always turned you on, but it had never happened before, and you felt good being someone's personal fucktoy. Then, the blonde pulls you back up to your knees and tells you to...
