Stop before things get too messy

Jimbo's hands are vigorously mashing and molding your bare breasts as your hand frantically tugs on his stiff erection.

"That's it," he gasps loudly as your rapidly jerk away while he tugs painfully on your nipples, "Don't stop baby, don't stop."

You feel his dick throbbing insistently and sense that his orgasm is almost upon him so you immediately cease jerking him off and release his dick.

"Whoa! What are you doing Titties?" asked Jimbo, his face an almost painful grimace, "You can't leave me with blue balls like this!"

"We're on the job," you reply sternly.

"Fuck that!" growls Jimbo, he reaches out and grabs two handfuls of your hair and pulls your head down into his lap. At the same time he thrusts up with his hips and rams his cock up between your lips and into your mouth.

As his shaft slides across your tongue and rams into the back of your throat it starts twitching and spurting, his cum leaping into your mouth and down your throat.

You struggle and **** at his sudden invasion but the hands holding your face down are too strong and you have **** but to let Jimbo sate his lust in your hot mouth. He is your partner after all, it's not like you can bite his dick off or anything.

Suddenly there is a knock at the car window. The noise causes Jimbo to relax his grip on your hair for a moment and you use the chance to break free, his cock popping from between your lips with a wet smacking sound.
