Flirt

You don't have any money, but maybe you could show her a good time instead?

"Eh, sure, why not," she says. Great! You retreat together deeper into the alleyway for a tryst. She leans in to pin you against the wall, and has her merry way with you! It's a quick affair but an intense one. You put yourself together again and walk out.

It's a few hours before you notice - you're starting to feel under the weather. You suppose getting all naked and rolling around in a dirty alleyway wasn't such a good idea? You've got turbo-hantavirus! You die!
