Not long

With your new found control of your muscles the doctor does not have a hope in lasting very long. You put him flat on his back you then squatted down on to his cock guiding it in to your pussy.

Once you have his cock inside your pussy. You tighten your pussy muscles and squeeze his cock and start fucking yourself on it.

He does not last long and you feel him squirt in your pussy. Then he went limp and slipped out.

You look at your clothes they are ripped like the hulks.

You see a lab coat on a hook. It is a tight fit but at least your covered for the time being.

But that did not realy matter at the moment the only thing you realy care about now was finding more cock preferablely big cocks and lots of them.
