Quid pro quo

'Wow, never pegged this guy for being so kinky back in high school. Nice too that he's hung.' Jennifer thought while she sucked down on your cock. She dwelled on that word.. thinking about how nice it night be to peg him later. All in good time, she thought.

Her sucking and stroking grew relentless.
Then you couldn't take it anymore, you exploded. Thick white ropes shot forth all over your body as she aimed your penis up.

You fell back into a chair, completely spent. She stepped into the store bathroom and returned with a damp rag. She cleaned you up, and the cold wetness of it quickly shrank your cock back to normal size.

"Oh fuck I expected freedom but I didn't expect that kind of release," you said. "I really owe you," you said stroking her hair, as she continued wiping you down. A little excessively, you thought, and you were starting to get cold.

"Oh you'll pay me back... many times over." She said.

"Speaking of that, how much does this cost me?" You ask.

"Oh. More than you know."

With that, you hear a 'snap' and your heart sinks.
