You see why I need to put you in chastity, don't you? No? Be honest with yourself. I believe you know... What is that? I cannot hear you... That's correct! It's because your penis is so little! Little dicks like yours do not deserve to cum. You've probably never satisfied a woman. No? No, what? I want you to say something! say, "I have a tiny little penis that has never brought a woman to orgasm!" And since you've never cummed a woman, it wouldn't be fair for you to do so, would it? How long do you think we should keep that thing in a chastity cage? Be realistic...
I suppose I could just let you go out and find a plain-Jane little miss average to date and eventually marry, but you know what? I don't want to risk the two of you bringing more beta geeks into this world, so I've decided you'll spend the rest of your life locked up in chastity.

No masturbation, or one-night hook-ups at the club - you'll be confined to chastity indefinitely. We may meet every ten years if you like, and I'll assess your beta status - sort of like a parole hearing - and bring some of my bratty girlfriends to decide whether or not to end your life sentence.
But don't get your hopes up, loser. The decision ought to be unanimous!
How long will you have to be locked up? That is up to me. I might be generous and let you off easily.
Or I might be in the mood to make your cock so frustrated and your balls so blue that you'll be crying and pleading to be released before it's over. Anything from a day to a week is fair game. I will, however, give you the option of accepting a longer chastity sentence...if you are stupid enough to accept it.
Until then, your cock will live in fear!
