a dangerous twist

My master looks down at me with a satisfied look in his eye. There is still a glint of mischief in it.

"My second wish will take a long time to explain" he says

"I have to do anything you want master"

Here's my next wish, from now on you are fertile, every time a living thing cums in you there is a 50% you will get knocked up by it. In addition to that whenever the situation presents itself you will subconsciously do everything you can to get cum inside you. Consciously you won't want to get pregnant but you won't be able to overrule your body. You can still ask people not to cum in you, you can even beg them, but your body will tell a very different story. Nothing will make you cum as hard as having cum in your pussy. You will do, say, and fuck anything and anyone you have to to get cum in you pussy. As the final part of this wish I want this effect on you to continue until I say its over.

I shudder with fear as I feel my pulse rise in anticipation.

"If that's what you want master"

"It is."

I snap my fingers and his wish is true, I can feel myself getting wet at all the sex that this could lead to.
