A couple of months ago my GF [25f] and I were invited to her best friends [25f] birthday party. The whole evening my GF was teasing me in different ways and gestured me to follow her at some point. She led the way from the living room to her friends bedroom and told me she wanted me to fuck her in her friends bed. The problem was we didn’t had any condoms with us and she didn’t want me to creampie her, because she was worried it could leak out while we were still there. So the plan was I would pull out in time and she suck me off for the last bit. Good plan in theory, right? So we started going at it and it was great. When I realized I was close to cumming I told her and pulled out, but it was already to late. I had passed the point of no return and came while she was still turning around. So there we were sitting in the bed with a wet spot next to us. We freaked out a bit, but ultimately decided to just leave it as is, not to talk to anyone about it and hope we didn’t run into someone when leaving the bedroom. We got dressed again and joined the others in the living room again for an uneventful rest of the evening. A few days later my GF told me her friend had told her someone came in her bed at her birthday party. Luckily she suspected someone sneaked in there to jerk off to her panties or something.
