I go to that beach a lot, and I have a thread going on OCC.
That said, I'm not sure if I saw your gf or her friend. A clear face pic of each of them (nude or not) would help. If your interested in giving me more info it might help me remember if I was there that day. In the meantime, check out my thread. For all I know, they're already on there. Either way, good luck. I understand your feelings.
