Employ the collar

You pick up the crazy, metal collar and the accompanying remote control. The collar has a cushion around it. It actually looks very comfortable. Just as you go to turn back to your assistant, you notice a third piece. It looks like a cock ring with wings. You scoop it up and hold the pieces out to Dr. Dee Throat. *snicker*

"Dee, we're going to use the collar today," you tell her.

"Very well, Doctor. I have a subject in the waiting room ready to go." She leads you out the back of the lab and into another room. This one is much more comfortable, but still sterile. The white walls and carpeting are only broken up by the tasteful and plush grey couches. One on either end of the room, about 5-6 feet apart. On one of the couches, sits a tall blonde. She has long, French tipped nails and an hourglass figure. Her long blonde hair lays straight and her make up is flawless. She has obviously spent a lot of time and money on her looks. You wonder if her tits are real. You'll probably find out soon enough.

You give her your best smile, but she doesn't notice as she is too busy texting on her phone. "Hello, I'm Doctor David." You like the way that sounds. "This is my assistant, Dr. Throat." You introduce yourselves as you sit on the opposite couch.

In a typical valley girl voice, the woman asks, "I'm getting paid for this, right?"

"You could say, once we're done here, you'll be loaded." You chuckle at you own joke.

Dee adds, "I think what the good doctor is trying to say is that you will be well compensated at the completion of the test." You chuckle even more.

"Whatevs," the blonde rolls her eyes and goes back to texting. "What am I doing anyways? Something about a medical collar for, like, lock jaw or something? I don't even, like, have that problem. Why did you need someone without a gag reflex to test for that?"

Dee looks at you and you gesture for her to put the collar on the subject. "Yes, ma'am. I'll need to put it on now."

Blondie doesn't even look up from her phone as Dee places the collar on her neck and latches it shut. She's doesn't pay attention to the description, either. "The collar specs state that it will provide full support to protect the neck, and when activated, will send a very mild electric current through the jaw muscles. You won't feel a thing. This will **** the jaw to remain open while keeping the muscles relaxed enough to prevent damage."

The woman just rolls eyes, "Whatevs." You're going to enjoy this. Dee is clearly showing her annoyance at this woman's attitude.

Dee comes over to you and hands you the remote and the final piece. You consider them for a moment and give the remote back to her. "Doctor Throat, will you please conduct the test?"

She smiles and nods, but remains professional.

You stand up and drop your pants. The blonde doesn't even notice. You're really going to enjoy this. You work the winged cock ring over your semi-hard member. You notice Dee out of the corner of your eye giving you an appraising look. She seems pleased. Sitting back down, you say to your assistant, "Doctor, you may begin the test."

Finally, the blonde looks up. "Wait, what's happening? Why is your dick ow..." She trails off as Dee activates the collar. The blonde's jaw pops open and she can only make unintelligible noises. With another button push, Dee activates the magnets in the collar and the woman flies across the room to land face first in your lap.

Balls deep in this woman's face with no resistance at all. You smile up at Dee. "A success!" You declare and she smiles back at you. "Let's start by measuring it's durability. Begin the heavy use testing!"

Dee flicks off the magnets and the woman stands back up, gasping and trying to talk. It all comes out garbled, though. Without warning, Dee engages the magnets again and the woman drops back down to her knees. She repeats this process several more times.

You lean back to enjoy your throat job. "A little faster please, Doctor." You order your assistant. "Let's really find out how much punishment it can take." Dee grins and complies. Rapidly turning the magnets off and on, the woman never gets a chance to sit straight, let alone stand.

You place your hands behind your head and just enjoy the rapid, hands-free throat job. You glance over at Dee and see that she is having fun as well. She's rubbing her thighs together as if she's trying hide how turned on she is.

Just as you feel that familiar rising sensation, the action comes to a stop with blondie's face pressed against you. You look up at your assistant questioningly. "Oh, Doctor, I forgot to tell you something," she starts. She goes off describing some experiment or other that you have no interest in. You wonder why she's even bothering you with this in the middle of your throat job.

That's when you notice the other woman beginning to thrash around wildly. Before she could only keep herself from falling over, now she desperately trying to free your cock from her mouth. You look over at Dee with a renewed sense of appreciation. That big brained slut! You continue to let her ramble on for a bit, taking the opportunity to fondle the blonde's big tits. They're real, all right!

After another couples minutes, you're ready to finish. "Doctor Throat, I think we're about ready to wrap up. Just a few more tests now."

"Yes, Doctor," she replies and releases the magnets again. The woman has just enough time to pull back and gasp for air before she is slammed down onto your cock again. Dee picks up a punishing pace and is now openly fingering herself under her lab coat.

Between your assistant's moaning and the blonde's gasping, you're ready to blow. "Stop!" you yell just when the collar connects to you again. "I'm cumming!" With a deep groan you unload the woman's payment directly into her stomach. You flop back onto the couch. "Ok, I'm done," you tell Dee, indicating that she release the woman.

The blonde falls to the floor gasping and groaning. The collar is still activated so she can't actually form words yet. Just as you go to pull your pants up, you catch sight of her phone that was discarded at the beginning of the 'experiment.' You get an idea.

Picking up the phone, you trail your cock across it, leaving a smear of cum across it's entire front. You toss it on the ground in front of her. "Think of me when you use it." You say with a wink.

You pull up your pants and head back to the lab, leaving the mess behind you.
