Cut down her throat.

As Seth yells cut you grab hold of Kelly's head with both hands and **** her all the way down to the hilt of your cock.
This time she does gag but you don't care.
Wave after wave of orgasm tears through your body as you empty your entire load down Kelly's throat.
It seems never ending and as you stare down at her you watch as it starts to spill out the corners of her mouth.
She takes her hands from your balls and cup them under her chin so any over spill won't go to waste,swallowing as much as she can with each jerk off your shaft and thrust of your hips.
"Fuuuck,fuck FUCK!!" you cry out as the final drop fires from your dick.
You lean back in your chair,out of breath and face flushed and let go of Kelly's hair.
She takes her mouth from your still hard member and smiles as cum drips down into her hand before swallowing what's in her mouth.
"Mmmm yummy" she winks at you.
"Well Kelly" Seth asks approaching the desk "You think he can deal with the pressure?"
Kelly laps the cum from her hands lick a cat lapping milk.
"Oh yes" she grins,her lips glistening with your load "I think he can handle the pressure"
