Description: HUNTC-528 "This is also an important test for commercialization, so do it properly!" I got a job at a condom manufacturer, and I'm the only male there. For some reason, a hardworking female science student uses me as a guinea pig every day. In order to get more realistic data, I decided to use my penis for all the tests that had been done with model male genitals up until now.
