You pass out, she "heals" you

The serum she gave you was a little too potent. All the blood went rushing from your head to your penis, so much so that you fell over and passed out.

You're only out for about a minute. When you start to come to, you open your eyes and there's Kelly, furiously jacking you.

"Can't believe this fucking pussy. Passing out from this. I'm so pissed right now," she mutters.

The sensation of her hand rubbing up and down your shaft is incredible. You pretend to still be out and enjoy it. After a few moments, you feel that familiar sensation as it rises up. Then you let out a moan as your cum erupts filling the beaker.

Kelly is startled then yells at you, "YOU WERE FUCKING AWAKE!??"

You are too much in the afterglow to reply.

"And here I was doing this for no reason?? Oh you are so fucking dead."
