A drunk vagrant

"Amazing that you're immune to STDs and can't spread them," you say.

"Yeah, I hate condoms," says Krissa.

"I guess it doesn't hurt you orgasm at the drop of a hat and have pretty much no shame."

"Yeah, yeah, yeah, whatever," says Krissa.

A man stumbles into the alley. He's about 50, wearing baggy, stained jeans, a ripped white dingy under shirt and mismatched shoes. He has a scraggly salt and pepper beard and greasy hair. He has a bottle of cheap wine in one hand. He walks up to Krissa and smiles, showing his dingy teeth. "How mush for a blow jub?" he slurs.

"For you, one dollar," you say. "She is kind to gentlemen in your condition." You turn to Krissa. "Get to work."

Krissa grabs a discarded piece of cardboard and puts it down before the man and kneels on it. She undoes his pants and pulls them down.

You can smell the man. He reeks of BO and urine. You smile as Karissa tries not to gag. She looks disgusted as she takes the man's penis and starts to stroke it. He gets hard, and she slowly and tentatively takes his cock into her mouth. The man takes a swig from the bottle, and some of the cheap booze drools from his mouth, down his chin and beard and dribbles on Karissa's head.

You smile as you enjoy Karissa's degradation. You have her get turned on by this despite the fact it disgusts her; in fact, the more disgusted she feels, the more turned on she gets.
