Description: Thank you so much for joining our study. I’ll just be observing you and taking a few notes while you masturbate, and when you’re done I’ll need you to cum into a cup. Don’t worry; this is purely scientific, so you’ll just jack off as you normally do, while I watch. The study is fascinating as you pass through the phases of arousal, full erection, and of course… the ejaculation phase. The most important part, really. Now after you've cum into the cup, we'll start the second part of the study. Please eat your semen. Yes, really… drink up!
