I haven't cum in a week, but I have been teasing and edging myself a bit most days. Yesterday afternoon, I spent about an hour playing around and edged twice. After the second edge, I laid in bed with my eyes closed, just catching my breath and cooling off for a while. Eventually, I thought about going to take a shower.

But then I felt the slightest twinge in my bladder--it wasn't a need, just the very first awareness that my bladder was starting to fill. I had drank about a liter of water while edging. The mental gears started turning. Horny brain was still running the show and I decided to do a hold and then eventually go take that shower and finally let go in there. I know it's really on the tame side of things, but I've actually never pissed in the shower before. I always use the toilet before taking a shower, so I just... never thought to do it in the shower instead.

I spent the next few hours naked in bed and letting my bladder fill. I continued to drink water as I pleased, but I wasn't pushing to drink a lot. To pass the time, I played Steam games for a while; watched YouTube videos; worked on some writing. The more my bladder gradually filled, the wetter I got. I was laying on my stomach for most of that time, providing a bit of extra pressure. I kept my legs spread slightly, just enough that I could rest my mons directly on the bed. Again, extra pressure, but against my outer lips rather than my bladder. If I pushed my hips down, my lips would just barely press against my clit; it was more than enough for me to constantly feel it.

I didn't want to be caught short and not make it to the shower, so when I felt the first leak, I admitted it was time. Only a few drops had leaked out, but it had me even more desperate to empty myself so I jumped out of bed.

It was evening and my housemates were home. I really didn't want to be running naked through the place, so I tortured myself for a few more seconds as I threw on jeans and a t-shirt as quickly as possible. Then I grabbed my usual shower kit [towels, hair brush, etc.] and bolted out of my room and to the bathrooms down the hall. Bathrooms, there's two, which is why the thought of being locked out never came to mind. It turned out that both bathrooms were empty, anyways, so I felt relief as I rushed into one and locked the door. My bladder clenched at the sight of the toilet, but I managed not to leak.

I dropped my kit on the floor and turned the shower on. Seconds felt like minutes as the water heated up; once again, I was dragging out the holding for as long as I could. My left hand was pressed against my cunt as if to physically hold back the flood and my right hand was beneath the spray of water to gauge the temperature. It made me leak for about a second before I got myself back under control.

As soon as the water was barely warm, something I could tolerate, I jumped in and leaned against the wall. I faced the spray of the showerhead and spread my legs apart and... nothing. My body was too wound up that this wasn't a toilet, that I was standing up, that it would get all over my legs... My bladder screamed for relief, but tension was holding relief just out of grasp. A drop or two would leak out, each one a small flash of blissful relief.

I needed so much more, but my body was still refusing to co-operate. I closed my eyes and tried to relax as much of my body as I could. A few drops became second-long spurts became a thin but steady stream. I moaned as the pressure in my bladder finally gave way to almost orgasmic pleasure.

Once I was truly, fully letting go, an impulsive thought brought my hand into the stream. It splattered across my palm and fingers and I was shocked at how warm the urine was. I suddenly pressed my hand directly against my pussy. I bore down, trying to piss even harder and the sensation of such a strong stream hitting my hand made me shake. I yanked my hand away, scared that I was going to cum. I don't know how I managed not to pleasure myself then and there, I have no idea where the willpower comes from. I was impossibly aroused, my legs were shaking.

I continued to push, forcing out as much piss as I could. Finally, a few weak spurts and then nothing. Absolutely drained.

I finished my shower, re-dressed, then caught the next bus. I had to get out of the house to cool off and bought a fast food sundae to help chill myself down.

I feel like this was a pretty tame experience, but it still really turned me on. I really enjoy seeing women piss standing up--in the shower, outdoors, at a urinal, anything. It's very arousing for me. Even writing this all out here got me worked up again, wanting to touch myself.
