My friend asked me to come over and fuck his girlfriend. I'd met her a few times and she was bangin' hot. I wasn't supposed to talk to them or make any noise. I had no clue what to expect. I came over and she was blindfolded and had a dog collar with a leash he was holding. He took off her panties and I took off her bra and he started screwing her from behind while I fucked her face. We switched positions a few times. While I was fucking her, he started rubbing her clit and I got a little weirded out with a dude-hand less than an inch from my junk but I certainly still had a good time. I tried like hell to hold off while I was fucking her from behind. Had to stop and go to her mouth again. Eventually I came down her throat without warning her or anything. She seemed to enjoy it. Then I left while he was still banging her.

It was a lot of fun and it's hot to think that she has no idea who else was fucking her. The downside is that my chunky regular FWB might not be hot enough for me anymore. I really want some vanilla one-man-one-woman sex with someone I'm really physically attracted to now. Then we can spoon and talk about feelings and get breakfast the next morning.
