We let them watch at a CA resort [MF] [Group]

My gf and I (both 28 at the time) were in town for a wedding and decided to take a day for ourselves. We found a naked resort near Palm Springs and spent almost all day there. It wasn’t peak season so there were only 3 other couples there, besides staff. One couple were fucking as soon as we walked in/while given the tour. They left maybe an hour later and didn’t say much. The other was a middle aged couple from the east coast who we shared a joint with. They were lovely ppl and after a while of smoking with our feet in the hot tub my gf decides to suck on my cock, which she had been playing with since we all started smoking. As soon as my beautiful red head gf started sucking, the other couple took that as the cue to start playing as well.
They played next to us for a bit, mirroring our play, then moved to the big circle bed in the play room. From the hot tub I watched them fuck while getting some magical head ;) I hoped we could get better seats to watch the show but my gf dragged me along to the bathroom and that couple went to their room by the time we got out.
The third couple (who were closest in age to us) wandered from there room where they had clearly been enjoying themselves. Meanwhile, my gf and I picked up where we left off but this time on the circular bed. My gf was on all fours sucking my cock while I stood off the edge, leaning over to spread my gfs cheeks so I, and the other couple watching, could see how wet she was. Just glistening. I finally got so heated I did something I had never done before, except on stage (another story lol): I turned my gf around and licked her from clit to crack. At first she was surprised but she is a little submissive and likes when I take control. By this point, the guy from the other couple laid down on the bed in front of my gf, with his hard cock pointed straight up. As I fucked my gf and she moaned I could see he was pulsing with excitement and his girl called him to there room shortly after. I can’t properly express how amazing she feels but calling her “the best I’ve ever been with” is very understated.
We didn’t ever wanna leave, to say the least. We had only booked it for the day, not over night. And the staff was kind enough to let us stay into the evening. Eventually we put our clothes back on and left but we experienced something we’ll never forget.
