Ok here goes, my first lay report.
Back story: Ive been hanging out with this HB7 and have crashed at her place after a night on the piss. Nothing happened, and I was becomming a bit too chummy in a LJBF way, so I froze her out and in 1 day I got a text saying "you should come out tonight, it will be fun".
My friend and I got their early. Shot some pool, chilled out with a few people there. I went to the bar and EVERYTIME I was approached by women asking me to buy them drinks. First up I was rude and simply said "no", but saw my error and evolved to "I don't buy strangers drinks", then they would tell me their name blablabla, but I digress.
So the HB7 arrives, we continue to chill playing pool, I kind of ignore her, then give her attention. She leaves with her friends, I acted cool, said "no problem was fun, have a good night". I then got a text back saying "you and gary should come stay here, everyone is sleeping here". So I figure sure but text back "sure, but gary wont be sleeping in the room with us".
I get there, her friends are asleep on couches, so we fall back to her bedroom. We get in bed, have a little tug battle for the blanket and I go straight in for the kiss. AANNNDDD things go from there

, I am a gentleman, so no dirty details

I am not interested in this girl as a G.F, I just want to keep her as a F.B.
If anyone can offer their advice/past experiences on how to keep it about sex and not a relationship I'm all ears. So far I have been VERY careful to avoid future speak, e.g "we should go see a movie soon" etc.
