I live in a caravan park where there are public bathrooms that long term residents of the park can access, these public bathrooms mind you, t hotter AND have more pressure then most of the ones that are in the actual houses.

So of course, when we moved into the park like 5 years ago, I started going to the public bathrooms instead of the ones in our house because they were nicer, I ended up discovering that one of the shower stalls right at the back of the bathroom had more pressure then the rest.

This of course became "my" shower stall, and every night I would go to it and have a shower, I, seeing the opportunity before me, started to spend longer and longer masturbating in this shower every day, every new thing I would try, would be in this shower, I spent hours every week masturbating in the shower... All in all I have probably cum onto the floor of this shower stall hundreds of times...
