So I joined this new gym and after my workout I wanted to try this new sauna they had and it was connected in the locker room so I stripped down butt naked and start heading that way I look for a towel but they are all out. I think nothing of it cause it was late and there weren’t a lot of people around. I head to the back end of the locker room open the door that leads down a short hallway and a corner to the sauna. I get in it’s empty so I get comfy and close my eyes to just chill about ten mins in I hear the door open and in walks in this fairly cute girl in here mid 20’s in a bikini! I look at her and shock and she looks at me in shock! I can see her staring at my cock and I embarrassingly cover with my hands and try to leave she just give a nervous laugh and says you must be new but this is a shared sauna and clothes have to be worn at all times it’s posted by the door! I embarrassingly say yes I am new and totally missed it she just giggles and says obviously as I stumble out of the sauna I can feel her eyes on me. I get back got the lovker room flustered but kinda turned on. Not sure how I will feel if I see here again lol
