How can i turn friend into fwb?

Horny teen lol, i am pretty sure it is hard to pull these kinds of things with girls of your age, the fwb usually occurs in the college stage. You can get the "poon", but the usual route for kids of your age is to date here for the month tht it takes and then get it. Or sooner, or longer depending on the girl. If she is really attractive she might put out more often.
