I (24M) have always been attracted to her (27F) and masterbated to her quite often. We were at this house party on Saturday night and it was quite a big house. I ended up going to bed there at like 4am. About 2 hours later I heard her come in. I was just in my boxers because I was way too warm. She came in beside me and she got very close to me. I didn’t move. I was hard straight away. I had my back turned to her and she started putting her hand around my body and grabbed my dick and was stroking it. At this stage I let out a moan because I couldn’t help it. I turned over and we made eye contact and just started kissing her. I got on top of her and started having sex with her and we did it very quickly so nobody would catch us. She was asleep when I woke up the next day but I messaged her after and we are meeting up tomorrow for more sex.
