You wake up feeling groggy but very satisfied. Pulling yourself into a sitting posistion you quickly check and everything is still there, you are still male- however the condom is still on your cock. An attempt to pull it off only created massive pain as the teeth dig in.
Inspecting yourself you find that though the teeth are there they are not visable, not only that but your cock looks somehow bigger! You play with it for a bit and it has indeed grown- its fatter and a good 1/4 inch longer! Your play of course wakes it up and you get a wonderful feeling as your dick grows to fill out the condom, streaching the sides of its prision- watching it grow its obvious that its bigger now and your hand quickly finds your shaft. If one ejackulation made it bigger what would a second do?
A big grin spreads across your face as you begin to jack off- the pleasure is better than before- oh gods this is going to be a big load!
