The events take place in a world where the social norm is to select a man for mating in special clinics. Men never see girls he breed with, only nurse. Everything must happen naturally, but with strict rules. What the video should contain: it's a man's POV. A nurse gives instructions before the sex procedure. I'll describe it roughly, the text may vary, and my only request is no insults. Let the nurse be strict, somewhere between a trainer and a scientist. "Welcome, subject 2208. This is a standard pre-conception screening procedure. Congratulations, the client has chosen you for the procedure. According to the contract, you cannot refuse, or you will receive the standard penalty of having your penis polished, without orgasm, of course. If you're ready to continue, sign my sole with your tongue and we'll continue." ...Before the procedure, we'll undergo a standard arousal test. If your penis becomes soft during the procedure, the company will suffer reputational damage. In that case, you'll be a test subject in an experimental program where we test sperm quality based on long-term chastity belt wearing and regular spankings. You don't want to be part of this program; you can rest assured, I wont stop. ...Now about the preparation itself. I'll carefully examine your chastity belt for any imperfections. Afterwards, I'll remove it for a scheduled cleaning. ...Now about the procedure itself. We respect the privacy of our clients, so during the entire procedure, you'll be gagged and blindfolded. Our clients have a premium package; they can request pre-whipping, electric shocks etc. Well, subject, you're in good hands, in mine. By the way, what do you think of my new idea? A remote that tightens or loosens the straps. Talking about it, l want to climb on you myself. You know, it's illegal. It's illegal to extract sperm from you for personal use, but nothing more. I know techniques to keep you from cumming for four hours. Don't tell anyone. Oh, you'll be gagged. I hope you don't refuse me, but if you do, you know the consequences. I can keep your face out of the auction for up to six months, without explanation. Imagine what a good boy you'll be under my command, not cumming for that long... You're ready." She then blindfold man, and in the next scene with a black screen, arrange some kind of surprise, the sound of an electric shock, a whip, or the client's voice voicing her insidious plans.
