German version - English version in the shop! Next, please! Ah, YOU again. You're getting more and more involved in this project, aren't you? I've noticed. Either you're very into science, or I'm the reason. Then let's get started. I'll take your hard cock out of your pants and start the treatment. Today the following things will be used to achieve ONE intense orgasm at the end: Internal stimulation through the urethra with a thick dilator, vibration therapy, stimulation with E-Stim and breath control with my gloved hands. This is going to be very intense, are you ready? A side effect will be that you will become more and more addicted to my treatments.
