私の痙攣するペニスからのハンズフリー射精、推定力とステンレス鋼の音

I start out with the small sound, getting my urethra ready for more. Beating off with a sound stimulates my urethra all the way down to the prostate. After getting things going, I move to a bit larger sound and add estim electrode pads to my dick. With the power pumping and my dick twitching, I add estim nipple clamps and continue stroking in and out with the steel rod. I start to orgasm hard and cum tries to push the sound out of my urethra. I pull it out and cum flows as my urethra spasms.
