Finding spa time has been a favorite activity of mine when visiting Vegas.
I've been to the spa at Wynn several times when staying there for work. It's usually about as exciting as hanging out naked in my room, and the few times I've seen other people in there it's been the kind of people who wear their robes over trunks into the steam room. The facility is very nice though. It's easy to imagine how it could be fun if anyone were there. I've used the privacy to jerk off in the sauna, steam room, and once room at the end with the large hot tub and cool down baths (like I say, it's deserted).
I've tried Paris, which is frankly pretty poor in comparison. Not as nice of facilities, too easy to see into the sauna, everything usually set too hot for me, although the shower area is nice. On one trip there was a guy who kept coming and going from the steam room, sitting closer to me each time. I eventually moved to the sauna, he followed me in and wanted to talk about whether I'd ever shaved my balls as he had done. We started to stroke a little bit until some guy came in with his phone. On the whole it's more fun to go back upstairs and try to see people on the cosmo balconies.
Luckily, each experience gets better! I've been to qua twice. The first time there was a guy way older than me following me around, trying to touch my leg. (I'm not so attractive or anything, but I'm happy to walk around naked in a spa.) When we were finally alone in the steam room (qua has a fantastic steam room) I started jerking off and his eyes about popped out of his head. I think he was trying to provide cover in case anyone came in and tried to use the shower but it was way too hot. I felt a little bad for laughing at him. He wanted to go to the front pools and I said no, then he told me about how he was going to his room to jerk off. If he'd been 20-40 years younger I might have been interested, but I told him I was going to come in the steam room, and I did (alone). Hung around a little bit because there were a couple of good looking people floating around. An asian guy in his 20s with the biggest penis I've ever seen, and another guy who was in great shape. We talked a little bit about the old guy, but didn't do anything.
Second time to qua, it was a very busy Saturday. Stepped into the steam room at one point and couldn't get space to sit. Walked in on a group jerking off that split up when someone was being given a tour, then saw a bunch of them individually after. Young black guy who was great at getting other people going every time he opened his towel. He almost immediately told me he liked my cock and how it would stretch him out. We jerked for a couple minutes at a time whenever we ended up in the same room together, which was frequent, and I let him stroke me or play with my balls as much as he wanted. Spoke of going up to a room but I was already checked out and he was staying with people. Shame. Later on, an older fella came in and immediately went to work with both hands. The young guy and someone else came in somewhere in the middle, joined in, and both of them got a turn each to play with the older guys balls and to get sucked a little by him before he came in the steam room. There were two other guys who weren't really into me but when the young guy was there would join in, and I saw both of them cum too. Ran into the old guy in the shaving room and listened to his stories about good times at other spas. Through all of this I'm jerking off but not finishing, because it's been a week for me and I'm just enjoying the tension. I go to the pools in front at some point with the young guy. I get in while he takes a chair, and I'm at a great level to sit and watch him stroke for a while. Eventually another guy comes in and sits next to me, carefully avoiding eye contact with anything and anyone. Take a break, juice, pretzels, guys watching golf on TV, through the showers, back into the steam room. I'm alone, so I'm stroking and the guy from the front comes in. I don't bother covering up, I just take my hand away and I'm sitting there, still hard. He sits right next to me, also uncovered, chit chatting about being hungover this morning, his friends, whatever. We start jerking. We stroke each other a little. He plays with my balls while I jerk off. It's gotten a little quieter / less crowded so I'm trying to decide whether I want to talk about going somewhere, or if I can just blow him a little, and then he's grabbing at my ass. He ends up fingering me while I finish myself off, and he cums right after. He says he'll be right back and leaves, I mop up a little with my towel and pretty much go shower, dress, and drive home after that.
I fantasize a lot about clicking with someone and taking it to our rooms, but short of that, this last trip was just about everything I could have hoped for. Anytime I saw someone sucking off someone else in that steam room, I couldn't believe my luck!
