I had been holding my piss in all day, waiting for night. Before I got in the shower I thought I would burst any second. When I got in feeling the hot water trickle over my breasts and body made me had to piss even more. I nearly pissed right then. But I made myself hold it. When I got out, I dried myself off. I put on a nice pull up. Just feeling the inside of the pull up made me horny. I went into my room and layed down on my bed. I relaxed all of my muscles and I let loose into my pull up. I could feel the pee warming up my ass and over my clitoris. It felt so good. After I got done wetting myself I got out a bath towel and bunched it up, and put it on my computer chair. I sat down onto the towel, and felt my warm, wet diaper squish on my vagina. I started watching pissing porn, and rapidly humping my squishy diaper, Feeling the insides of my diaper rubbing against my clitoris made me orgasm so hard. It felt great, I can't wait to do it again! :)
