Last Saturday I met up with a few people for an outdoor festival. There's this one girl who thought I was a police officer at first but ad the day (and night) went on, she seemed really into me with virtually no effort on my part.

Anyway, we sent only a couple of messages over Instagram, and I'm taking the conversation to WhatsApp to get to know her a little but better and escalate a little bit. She agreed, and my goal here is to fuck her, so how should I approach this?
