You have been cumming far too often to my sperm collection clinic. I think you're just a pervert with a tiny dick and useless balls. If you want to be welcome here again, you need to prove to me that you don't have a useless set of balls and tiny dick. After your exam, it seems you just don't measure up. The nurse uses her metronome to make you stroke to the beat, faster and faster, until you produce a proper sample.
