Anal on the trail and being watched

[Maiken68]

It was July and hot as hell. My gf and I loved to hike the rockies in ABQ. We were several miles up, above the tree line. Georgeous day, when she got horny and wanted to have kinky sex fully nudes right there on the trail. We hadn't seen anyone for hours so I figure no harm no foul. We had been going at it for 30 minutes or so, long enough that by now I was balls deep in her ass and she was already loving it, when I look to my right where we left our bags and our clothes. A man and a woman about the same age as us and very attractive, were watching us, touching each other and clearly very aroused. I was startled at first, but quickly realized what a huge turn on it was and so I took my eyes off them and back to watching my hard 9 sink all the way up my girls tight ass. I slowed my pace as to take more time to finish and give them enough time to catch up. I glanced over every few minutes and saw just how goddam sexy the other.woman was and also how the man's cock was longer than mine but not nearly as meaty. I remembered once my gf said she wished I wasn't so thick at the base so I could get deeper in her ass and dig in to reach her G Spot which was all the way up in her ass about 12 inches. I asked my girl how she would feel if I told the other dude to come give her ass the deep loving she desired, and then I could get a slice of other girls pie and Maybe, just maybe I could get my dick all the way up her ass without causing her to much ***. What perfect matches we were as couples for swap sex because we all had the time of our lives and because regular fuck buddies. We must have traded partners 100 times in the months following. You know? There is something so amazing feeling about getting as far up your lovers ass and just unloading a bucket of cum in there and watching it flow out of her asshole and down her legs. It's truly magical.
