You get under Jake's desk.

You drop to your knees and climb into the space under his desk.

Jake slowly steps around the desk, as you hear the sound of a zipper and the clink of his belt-buckle.
He takes a seat in the chair directly in front of you. His legs are spread slightly and the front of his slacks are completely undone, his cock on full display.
You move forward a bit, so you can get closer to it. You don't have any real room to move your arms so rather than stroking him off to get him hard, you have to just wrap your lips around the head of his shaft. You make use of your tongue, slowly swirling it around the tip, which seems to get him going.
Above you, Jake says "Oh, that's new. Who taught you that one?"
You pinch his ankle, the only response you can maneuver in the position.
He just says, "Careful..." and then you hear the sounds of shuffling papers. You're a little surprised that he actually does work here.
His cock starts to grow inside of your mouth. As it does, you start to suck it more and more. Eventually, his pubes start to tickle your nose with every downward movement.

You aren't sure how long that you kneel there, bobbing your head on Jake's cock. After a while, your knees start to feel a little numb, so it must be a while.
You're not very good at telling what time it is anymore.
Behind you, you hear Al say, "Sir, your 10:00 is here."
Jake says, "Good. Let them in."
The door opens and you can hear two people come in, only one of them is talking. His voice, its owner is unknown to you.
"Thanks for seeing... us..." The voice trails off.
"Who's your friend, Meadows?" One says, most likely referring to you.
"She is the fruit of our labours, Greggs." Jake says. You slow down the pace of your sucking.
"You plan on sharing her?" A new voice says, but it quickly adds an "Ow!" to the statement.
The voice that belongs to Greggs says, "Don't say shit like that to management, shitbird!"
"If she was free-use, he would have offered her to us." He continues.
The Shitbird mumbles something under his breath. You don't hear what it is.
Jake says, "He's right, Knicks. In this business, you get what you pay for and their isn't a single dime of your money in her. So, keep that kinda crap to yourself and sit down."

Quickly, you lose track of what they're all talking about. They start talking about marketing and budgets and other stuff like that. It goes way over your head. You make a mental note to brush up on your corporate-speak, just in case. Maybe you could buy your way out of this life by selling some juicy company secrets to some other big-money outfit. Maybe.
Jake bumps a knee against your head, reminding you of your job.
You resume your blowjob in earnest. You throat his thick shaft as deep as you can manage, the spongy flesh of his tip hitting the back of your mouth. Suddenly, Jake's knees snap together, holding your head in place. The veins along his shaft begin to pulse. Then, hot cum shoots down your throat, giving you **** but to swallow the salty stuff.
The cock begins to deflate. But, being a consummate professional, you keep it in there. And soon enough, the shaft starts to come to attention once again and you begin the cycle anew.

Blowjob after blowjob. Load after load. You continue for what must be hours.
At some point, Greggs and Knicks leave and the voice of a woman replaces them. You never catch her name, just some vague talk about breaking in a girl of her own.
"So, you just left the whole personality in there? Completely intact?" She says.
"Well, I love slipping it to a real nasty bitch. That's why I hang out with you."
"Oh, really?" She says, laughing.
This woman is Jake's friend, apparently. Good friends, by the way he lets her speak to him.
He leans back and pulls your head off of him. You suck in a huge breath of air, having only used your nose for some time.
He says to the woman, "You want to give her a go? I can't attest to how well she eats pussy but she can suck dick like a champion, that's for sure!"
"Nah, I can't. I gotta phone those idiots in Washington. See how our FDA approval is going."
"Alright." Jake says, and pushes your head back onto his cock.
The woman leaves, saying "I'll take a raincheck on that, though."

You end up swallowing two loads after that.
