I think it has something to do with the bladder pressing against my g-spot or something, but when my bladder's full, I masturbate more.

This is unrelated to my piss kink, but I suspect penetration sex would feel better on a full bladder.

I'm saying this because my bladder is full rn, and I am humping my pillow and I feel like cumming any second.

Update 1: I've been edging with my full bladder for the past hour. Usually I play casually but the dms are inspiring me. I'm going to edge until I can't take it any more and drink a lot of water will replying to dms. Once I can barely hold it, I plan to go to take a shower with a makeshift dildo in hand and fuck myself with an overflowing bladder

Update 2: Sorry for the late update, things came up.

After another half hour of edging, I couldn't take it anymore. When I stood up to shower, I couldn't even stand straight. I felt like a dog with a tail between its legs while waiting for the water to heat up.

So I went in, as planned, fucking myself with a full bladder. It was intense. The urge to pee was so strong, I actually couldn't feel anything else. All my senses were focused on my bladder. So I guess if I were fucked like that, I probably wouldn't be able to focus. So I let go while pumping my pussy, piss running down my thighs. I had the idea of rubbing my clit while peeing, and that was pretty hot. Half way through, I couldn't pee. I think because I was so well potty trained, I couldn't relax enough to get the rest out.

I finished it off on the toilet and came a couple times. Overall, I probably wouldn't do that again with a SUPER full bladder. It was uncomfortable and hard to focus on pleasure. I don't even know if I came while doing it because the urge to pee literally blocked out everything else lol.

So yeah, that was a learning experience, thanks for reading.
