First time posting so bare with me!

I’m a 28F and 5 years ago I had an encounter that really exposed a new kink for me. I went to the gym like I normally do three times a week with my boyfriend. I decided we should go hit the sauna. We went in while the steam was pumping in the room so visibility was really poor, but we managed to find a couple of spots on the bench in the second row up.

My boyfriend was the handsy type so it didn’t really surprise me when I felt his hand working its way around me and onto my breast. It must’ve been the steam because I got all tingly from his touch and my hand went immediately to his shorts. I started rubbing his dick through his shorts while his hand slid into my sports bra to play with my nipple. Idk about you but my nipples love to be messed with and it sends sensation through my whole body. I pulled the string on his shorts and slid my hand inside to get a better hold on his dick. He went from zero to rock hard so I just kept pulling and stroking, once I felt his hand sliding down to my shorts I knew I was done for. His hand slid down the front of my shorts and knew right where to go.

I can feel the mess he’s making in my pants and I could take it anymore. I eased his shirt down to get his dick out and moved over him. Instinctively he slid mine down far enough and I sat down on him facing away. At first I was grinding on his rock hard dick, feeling my wet mess glazing it. Rocking back and forth sort of slowly but steadily. That’s went the steam started to dissipate…..

I looked across the sauna to see that WE WERE NOT ALONE IN THERE! Sitting against the opposite wall was a man, probably mid to late 30s, with a look of wide eyed disbelief. I was shocked and wasn’t sure what to do. I was so horny that my first instinct was to slide my boyfriend’s dick in me and start slowly moving my hips up and down as I leaned back against him. The man across the room just sat there still in awe of the show he was getting. The look he had somehow just turned me on even more. I’d never had an audience before but I could see that he was pleased with what he was seeing.

I started to pick up the pace and bounce a little more aggressively on my boyfriend’s dick. I found a rhythm and angle that was hitting so good and I just locked eyes with the other man while I could feel the O-train coming. Feeling emboldened, I asked across the room if he liked watching me getting fucked. He didn’t respond but his expression definitely did. So I said, “Then pull that out and show me that you like it.” Without hesitation the man pulled out his dick and started to stroke himself. I sped up to try to match pace with him and that sent me over the top. I had probably one of my top 3 orgasms of my life while I watched this stranger jack off to me riding my boyfriend, who at this point was basically just a dildo at my service. All of my attention was on the other man.

As I continue to bounce through wave after wave of ecstasy my boyfriend starts to get a little louder in my ear and asked me “do you want him to see you get filled for sprayed?” I didn’t even miss a beat and told him to cum all over my pussy. He grabbed me by the hips and forced me harder up and down on his dick until right before he needed to pull out. He grabbed around my breasts and pulled me back against him while pulling out of me, shoot string after string on my pussy and up to my naval. Seeing that was exactly what the other man needed to finish, as he shot multiple shots halfway across the room in our direction.

The man was the first to get up, reposition his shorts and leave the room. My boyfriend and I sat there for another minute panting on each other before taking a towel and cleaning me up.

I learned that evening that I’m really into being watched and I replay this memory often. Since then I’ve had many other more intentional experiences and each time is just as exciting as the last.
