OK, so this is my first post in FS but here it goes. I have been working with this girl who I kind of knew from back in high school and she invited me to hang out with some other people from work last weekend and we both had a bit to much to drink and ended up leaving the apartment and going to the back of my car (classy, I know.) She couldn't have sex because of her period but we managed to find other things to do. We ended up just sleeping on a couch together at our friend's house and in the morning she got up and left for work, I had the day off. The night after that, she comes over and we have amazing sex. I don't know any other way to put it haha. She's into the rough loud sex I've always wanted to have. Last night she was riding me and came all over me, I've never had that happen but it was incredible. After we had sex the last couple nights, we talked about all the things we liked and what we've done. That was almost as fun as the actual sex. A couple times we got so turned on by talking about it, we'd just fuck some more. We both know it's just for fun, but I'm wondering how long it can go on before one person becomes attached? Any of you have experiences like this? Good idea, bad?
