The "Sauna - Slut" I Fucked away in the hotel sauna!

I've never experienced that before. I had a seminar over 3 days in a really good hotel and wanted to do two or three sauna sessions in the evening to relax. The saunas in the hotel complex were all very small, but everything was very nicely done. And then I cum to the second sauna session and then this. A really attractive blonde was sitting in the sauna and kept touching herself in between. I just had to stop and watch for a while. I couldn't help but notice that my boyfriend was having fun down there too. And then I dared to go into the sauna. What happened next was simply unbelievable!
