I workout at a gym a few times everyweek. I don't get out of work until 11:00pm and since the gym is open 24hours a day I workout closer to midnight. After I finish working out I shower and then use some of the other things the gym has to offer like a hot tub, dry sauna and a steamroom. Most guys uses these things while naked. One time I went in to use the steamroom and was in there alone and naked when 2 other guys came in. They came in naked too and sat away from me. The steam isn't on constantly and only kicks in every so often and when it does you can't see 2 feet in front of you. Well the steam came on and must have been going on for at least five minutes before it finally turned off. After it did the steam began to clear up and things became more visible once again. The two guys were having sex. I am not gay but I did see the whole thing because for me to leave would have required me to ask them move because they were blocking the way to the door. I didn't want to interupt them so I let them finish. When they did they move out of the way I left but not before maybe giving them the wrong impression. I went to shower and they did so shortly too. It was a shower room, not individual showers, so you could see everyone. They began to talk to me and asked if I was gay. I told them I wasn't and was asked why I had an erection. They said I had one when I left the steamroom and they would have taken care of it for me before I left. One guy put his hand on my ass and offered to take care of it now. Him touching me caused me to start getting hard but I declined. He made a comment about how it looks like I might like it. I declined again and told him I needed to shower. They did watch me shower which I could see was causing them to get aroused. I guess me soaping myself up may have been arousing but I quickly did it, rinsed off and got out of there, got dressed and left. I never saw those guys before that night and haven't seen them since.
