You would have been thrown out for sure....if anyone of the sauna officials had noticed!

I swear that that was a true story.

Ok, maybe not 3 or 4 minutes of sex underwater...maybe it was more like 1 or 2, but I am not sure. And it was not heavy fucking but slow and sweet penis into pussy.

Besides my own experiences, I have seen a lot of sexual activities in these huge spas.

Additionally, get his cock sucked and fucking in a private locker room is not that special, no? You can see a lot of videos on your favorite porn site.
(Maybe you got me wrong: I meant a private locker room where you can undress and lock the door - not a group locker room like for a sports team).
Edit: maybe pool cabin is the right word?
