Crossdresser beats off with estim and urethral sounding

I'm dressed in lingerie, and my dick is twitching as estim pulse pounds through my groin over and over. The higher the setting, the more my dick twitches and throbs. I pull my balls tight and squeeze them into a ball stretcher. The estim pulse hits my balls and shoots out the end of my dick over and over. I push a sounding rod down my urethra and the feeling melts the pain and pleasure together until my body spasms into an orgasm.
