Giah and I had been dating for eight months. She is the woman of my dreams. Giah is super hot, 5' 4", fit but curvy with firm B cup breasts with large nipples, with long red hair and green eyes. More importantly, we had a lot in common and just connected on a day to day level.
But more important than her looks, or even our day to day compatibility, we were very compatible sexually. In our case that's much more important than you might think - neither of us were exactly monogamous by nature, and both of us were pretty kinky. We had an open relationship - we were both free to fuck other people, and we both took advantage of that freedom. The only rule was complete honesty.
With summer coming, we decided to take our first real vacation together. We are both trail runners, and we decided to take a two week hiking and running vacation in the Colorado mountains.
We spent the first week trail running every day in the San Juan mountain range in southwestern Colorado. While generally getting to bed early every evening so we could get an early start on the trail the next morning, we still found time for plenty of sex when we got back to our hotels. Not to mention one afternoon when we brought a blanket and fucked among the wildflowers in Putnam Basin high above Silverton, CO. A remote area that doesn't see many people during the week, though we would not have minded an audience.
After a week of running in the mountains, we took a couple of days break at a clothing optional hot springs in a tourist town at the foot of the mountains. People familiar with southwestern Colorado will know where this place is. This wasn't a spur of the moment decision; we had booked a cabin at the resort weeks ago, knowing that the cabins would have been full if we had waited.
I should mention that one fantasy that Giah had shared with me was to participate in a gangbang. Up until now, the most partners that she had at one time was two. I had participated in one of those threesomes, as I and one of her exes double teamed her, and she had shared with me the details of a couple of other such instances that had occurred before we met. We hadn't discussed making this a reality, and it didn't occur to me that this might be an opportunity to make it happen. However, unknown to me, it HAD occurred to Giah.
We checked in, left our bags in the cabin, and headed to the pools at about 4 pm. We both stripped down. Most of the guests were similarly naked, though a few modestly wore bathing suits. We spent several hours in the various pools, taking breaks to cool down, and once briefly back to our cabin for a light dinner. Giah was getting plenty of glances from men (and a few women) in the pools. During the late afternoon and early evening there wasn't much sexual behavior; it was technically against the rules.
However, at 9 pm the pools closed to day customers and remained open to people who were staying in one of the cabins or camp sites. We knew from what we had read online that it got a little more ... uninhibited ... after 9. We looked for a pool that didn't have anyone else in it and waded in. We started kissing; I rubbed my cock between her legs. My hands were rubbing her glorious ass. After making out for a few minutes, she reached down and put my cock inside her hungry pussy.
"Oh, God, fuck me, I love your cock so much. Harder, faster." I complied, kissing her as I drove my cock inside her, deep and hard. "I'm going to fucking cum, harder, faster" she said. Soon she was cumming on my cock, and I was filling her with my seed.
At that point, we noticed that there were two men at the edge of the pool watching us. We looked over at them, and Giah said, "Sorry guys, there weren't any people here when we got started. We didn't expect an audience."
One of the men said, "No problem at all, it was very hot. I'm Dave and this is Henry." Dave was tall and well built with long dirty blond hair. Both were naked; Dave's cock, semi-hard, presumably from watching us, was quite impressive, seven inches even though he wasn't fully erect.
"Nice to meet you," my sexy girlfriend told the two men. They weren't being very subtle looking at her small but firm breasts - her nipples were erect and very prominent - but then she wasn't hiding her interest in their equipment either, Dave's especially. "I'm glad we could entertain you." She looked at his hardening cock and smiled, "you definitely seem to like what you saw."
Dave responded, "for sure. Watching the two of you fuck was very hot."
We continued to chat; Giah was flirting overtly. She kept glancing at me, smiling, and squeezing my hand under the water.
Finally Dave said, "It was great meeting you guys, but we need to get going - we're meeting with four friends in our cabin to celebrate Henry's last days of freedom before he gets married." Almost as an afterthought, he said, "Hey, would you guys like to come?"
Giah looked at me with a twinkle in her eyes. I nodded. She said, "Sure, what's your cabin number?" They told her, and she said, "We'll be along shortly - we're just going to stop by our cabin first."
