I fucked my gf in the same room as my sleeping friend

Me and my gf were out with my friend and we decided to stay at his place because it was pretty late. After a little while we all decided to sleep. We basically had two mattresses on the floor, one for me and my gf and one for my friend. After a while my friend fell asleep and we could hear him snoring a bit and we were joking around about that. I said to my gf something like "yeah he's not waking up any time soon that's for sure" to which she then started pressing her ass against my dick which immediately got me hard. I knew what she was doing so I reached under her top from behind and started massaging her tits, and then I went down to rub her clit. She was trying hard not to moan but eventually turned and said she needed to be fucked. I was kinda worried about my friend waking up but she got me so horny than I pulled her panties down and started fucking her from behind. I had to cover her mouth to stop her moaning too loudly when my dick slid into her soaking wet pussy but I couldn't slow down because she felt that good. After a while I turned over and she climbed onto my dick and started riding me, which I then pulled her top off. I was getting so turned on seeing her tits bounce and she was riding me and trying not to moan. After a good time of a few other positions too I told her I was about to cum, and then she suddenly got down and took my dick into her mouth, sucking it intensely, trying to take it all into her little mouth until she swallowed all the cum I'd shot out. I tried to sleep after that but I was still so horny with the though of it that she ended up having to give me another blowjob during the night. My friend never seemed to mention anything in the morning so I guess there really was no waking him up.
