Shyness and uncontrollable pleasure... that's peeing. I can't stand it in my pants and I can't stand it, I'm incontinent, I'm stimulated by the high-speed friction of my cock, and I'm peeing continuously, and I'm shaking my whole body and drawing an arch, and I'm going to have a lot of incontinence, and I'm going to have a shame and pleasure from my urethra. The covered liquid splatters!
