Don't say anything.

From Create Your Own Story

You don't really care, he's not worth the effort to try to stop him. You just hope letting him cum will get you the cash.

Eliot pulls your arms behind you and presses you against the fence, squeezing your tits against the gaps in the chain links. He pressures you from the rear until hot semen spills into your ass, lubricating for real this time and letting Eliot slip even deeper into you. He pumps a few more times, finally fucking you well enough to get you to feel something. But it quickly subsides as Eliot's dick softens.

"Hey, you know you already came, right?" you tell him after a minute of his flaccid cock ramming around in your butt.

"Didn't say I had to stop after that," he says. "You said fifty bucks for your ass, so I'm getting what I paid for."

You sigh and let him play with you a little while longer. After a five minutes, you feel the head of his dick perking up again, getting hard from the smooth entry with his cum. You spread your legs a little and welcome the dick, able to genuinely moan for the first time this evening.

But then Eliot pushes you down and turns you around to face his crotch. "Clean it," he says, pressing his dick and balls into your face.

You try to push him back. "What the hell? I said I'd give you anal, that's all."

"Not a chance," he chuckles. "For fifty, I'm not cleaning myself up."

• You guess that sounds fair, and start sucking his dick.
• Spit at his dick and demand the rest of his cash.
• You're done with Eliot's behavior. Suck him off, then bite him off.
