Corrupting Bonnie

The story starts with a sexy young 18-year-old girl named Bonnie. She has a perfect body and a perfect face. But she also has serious money problems. She got an eviction notice, and wrecked her car. She had no money to buy another one. She made minimum wage at a fast food joint. Soon she would find herself carless and homeless. Things looked hopeless.
Then a handsome stranger made her an offer. He would give her more than enough money to fix all her problems, but with a catch. He wanted something in return. He wanted Bonnie. The stranger, a man named Carl, wanted some of that perfection of hers in return.
The stranger made her an offer. He would pay her cash in return for doing something she fantasized about for years. Something taboo. Something dirty. Will she give in, and will it fulfill all her fantasies or will she just feel used and dirty? Will the stranger named Carl save her or cause her doom?
