You may cum but...

[baloo]

You may cum alright, buut you must go over the edge precisely when it turns 15 past the hour!

You may cum but you must attach 1d6 clothespins to your genitals before you do so and you can not remove them. If any fall off you must replace them.

 

[MessyAshy]

You may cum but the world will know. the method, the duration, the porn you watched, and your name and picture will be sent to every phone in the world.
