Best friend-next-door/sex buddy

Doe is probably the closest female friend you've got right now; The "Grace" to your "Will" (except for the fact you're straight). Since middle school, you've been tight with each other. You tried dating a couple of times in 10th grade, but things didn't go so well. Even so, you've decided to remain friends.

A year ago, when you were planning on hanging out at Doe's house for the long weekend (since her parents were out -f-town for a few days), the 2 of you ended up making-out, which led to the 2 of you sleeping together. You regretted it at first, but after talking it over with Doe, the 2 of you reached a bit of a pact: If both of you are horny, you'll sleep together, no strings or emotional problems attached. So far, it's worked-out reasonably-well.
