Sauna and steam action is the best! Right before covid-19 closures, i was at the gym mid-morning. A quiet time and hopped into the sauna for a few minutes. Noticed the custodian noticing me, but thought it was more of a suspicious look, not a curious one. A few minutes later he came in to "mop" the floor, which was a bit surprising since there wasn't really anything to clean up. And then suddenly it dawned on me, to spread my legs just a bit and I noticed his curiosity was piqued. From that point on the pleasure was all in the tension and the subtle back and forth interactions and expressions of interest. He finally whipped out his dick for a short while, thick and well hung. And then poof!, someone else arrived and the mopping was done.
