The previous posts mainly dealt with typical spa features like massage jets, bubble benches, neck showers, jet cages and the like. This article is about the pleasurable fact that most spas and sauna parks in this region of the world (central europe) are nudist facilities. That is, you can (and should) use the facilities without swimwear.
Of course you can wear a bathrobe, or a towel around the waist while you are resting between using the saunas, and usually it is required for the restaurants. But effectively, it is absolutely normal and accepted to be naked almost everywhere on the premises. And even in areas where covering yourself is required, your private parts are still easily accessible... However, walking around with a boner or publicly masturbating would not be accepted, obviously. So you still need to be cautious, but it is much easier compared to areas where swimwear is required.
Showers
The first thing one usually does after stripping in the changing room is taking a shower, obviously. Shower rooms are the first opportunity to "get into the mood". Sometimes, the showers are separated by semi-transparent or opaque walls, so you can lustfully soap up or do some wanking without being detected. And if you are lucky, you might have the shower area to yourself, so you can do what you want, anyway.
First, there are the "normal" showers, usually right after you leave the changing room. At one spa I know, there are japanese-style lavatories (Sentō); you can see myself using one of those in the video.
And second, many spa areas feature special showers, sometimes called "adventure showers". The come with features like rain shower, sideways shower jets, colourful lights, pleasant smells, music, and the like. Depending on their construction, they can be very pleasurable. Here are some impressions:
Saunas, steambaths, and the like
Obviously, the sauna cabins, steam baths, vaporariums, Turkish baths etc. are the cornerstones of any spa. If a place is not frequented too much, you might be able to have them to yourself for some time. What you're doing the is only limited by your imagination... While good old manual wanking is the obvious technique, some steam baths lend themselves to humping/rubbing action. And I often smuggle a small plastic container with lube into the steam baths and enjoy myself in slippery teasing activity.
Indoor resting areas and relaxing rooms
Again, if you happen to be alone, you can enjoy yourself in unintended ways. The sofas, deck chairs etc. might allow for wanking in unusual poses. At one place I know, the relaxing couches and loungers are made of water-resistant material, so I used them for lubed humping - very exciting!
Outdoor areas
For my tastes, it's extremely arousing to be able outside fully naked. Most spas have outdoor areas with lawns, deck chairs, benches, little ponds, etc., and if you are lucky, some corners somewhat screened from view. It is exciting enough just being able to walk all nude through the area, and enjoy the sun and wind on your skin. If there are not too many people, I like to get more frisky, and do some teasing and wanking in the open.
The video below is a collection of scenes of enjoying myself at spas in the ways described above. I hope you get inspired!
