Hello. Welcome to my clinic. It says here you're here to deposit a sperm sample. Well, the process is pretty simple. You just need to jerk off in front of me, and I'll collect the sample. So go ahead. Get hard.
...Are you having difficulties? How annoying. Most guys just get hard at the sight of me. Don't worry. I've got a fix for this. We'll get that sperm sample one way or another.
I may find all of this distasteful, but I'm a professional after all.
