My favorite place to pee is in the steam room at our local rec, it's all tile and when there is a thick cloud of steam you can barley see 5 feet from you. Of course, like any pool I enjoy peeing in the hot tub, the lap pool and the kids area. The kids area has quite an aquatic playground in it, growing up in this town I soaked that thing with my piss and I'm glad I know I'm not the only one who did, kids like to pee in pools, it just feels good.
Still as an adult I like to swim or soak in the hot tub, drinking to fill my bladder and go piss in my steamy potty. You can hear it splash on the tile and the dark room with soft lights will rarely give you away. I've definitely caught older men playing with themselves behind the steam, usually they get up and leave but someday someone is going to get a pee show. I'll have to rub myself until I cumm because that pressure on my bladder make me so honey I squirm.
