Coed Cockteasers 2
Aw, that's so sweet. It's just not the same, is it dear? Touching hard plastic instead of a throbbing member? Of course I'd get along just fine with that, but it's not the same for you at all.
You want to know the best part about my stroking technique? It's that last, final stroke. Number 1. The final stroke. Because before that comes 3, and 2... so they know. I look them in the eyes and they now that if they don't orgasm on that last stroke, if they don't spurt their yucky load right then, then it's over. All that lead-up for nothing if they don't make it. And I can wait so long before I give it to them... but they have to be ready or else all they've suffered for is gone. Gone! It's so adorable, the look on their faces.
Of course, sometimes I'll just look them in the eyes and never give them that last chance. 1's not in the list of primes, you know. It's just one.
Someone that frustrated will do just about anything to cum, so before I untie them I always make sure to let them get soft. I typically have to leave the room for that part. Then I lock them up in this chastity belt I've got, lubed up condoms and all. I love a cock that's covered up like that, protected from all forms of stimulation.
The deal is that once they get up and go away, I'll mail them the key (which I hide before I let them up). Then, once they get it, they have to mail me the belt and lock back intact, or else I send a picture of them all bound up out on the campuswide email. That way I can guarantee that nobody cheats, and everybody has to wait for at least a week until they get to cum. I have a nicely organized collection of pictures now arranged by size, width and overall stamina. I've never lost a belt.
