So I've recently moved as the closed friend / family who are near is y gf sister  

  Ive moved in a week last night we al went out drinking with her fella and her .. After coming home around 3 am .. My sister and her fella were out cold within few minutes of getting back to there's .. So as he went to bed and my gf had passed out on the couch we both had to sit on the other 2 seater .. As she had a short top skirt on it rose up quite a lot .. As I put my hand on her leg and thanked her for putting us both up for a few days I started to rub her leg getting higher ever time .. As she didn't move my hand away I sat facing her I stopped my left arm for my right arm .. As I moved I got closer to her pussy afew times as we talked she parted her legs just enough for her skirt to lift up giving me a clear access to her pussy area .. As I kept rubbing and brushing my hand closer she began to ease up ...

 So I risked everything and started to rub her pussy .. She beg and to enjoy it as I slipped her panties to one side I ran two fingers up into her now soaked and wet pussy .. She began to really enjoy it .. As I stood up I held her hand walking out of the living room and outdoor in her back yard .. She dropped my pants and I was soon fucking her outside ... I lifted up her top revealing her bare breasts .. We fucked for what seemed  20 mins .. But felt a life time .. After we both came .. She and I made out before sorting our stuff out I returned to my gf .. Who was still passed out as she returned to her bedroom ..

 Neither of them both now about it and yes I do still fuck my gf sister when we're alone .
