"Well, if you say so," Catherine obliged, and the doctor smiled again.
"Excellent," he said, and he wheeled over a tank of gas with a nose mask attached. He turned the valve on the tank and placed the mask over Catherine's face.
"Now breathe in deeply," he said, which she did. As Catherine's head began to swim, the last thing she saw before passing out was Doctor Thorn looking down at her, that wicked smile plastered onto his face.
~~~
Catherine was lying down on a white bed in a white room surrounded by misty white light. She tried to look around but was finding it very difficult to move her head. She felt as though she were glued to the bed and couldn't lift any part of her body, no matter how hard she tried.
A man dressed all in black stood beside her, looking down at her. His face was masked in shadows but she could tell he was smiling. His smile was wicked, the smile of the Devil. She tried to open her mouth to yell but her lips wouldn't part. She tried to move away from him but her limbs wouldn't budge. She was helpless to get away from him, helpless to escape.
The man reached down to the front of his pants and slowly undid the zipper. Catherine's eyes went wide as she watched him, horrified. He pulled out a huge, throbbing cock and took a step closer to her. She tried to move her head to the side again, away from him, but she was completely stuck. He reached down and pulled open her mouth, leaving it hanging wide. Then, as Catherine watched helpless with her eyes bulging out of her head, the man lowered his massive, throbbing cock down into her mouth.
Catherine felt her tongue press down into the bottom of her mouth as this thing slid its way inside of her. There wasn't a thing she could do to stop him as he began pumping his cock in and out of her frozen mouth. She felt the head of it press up against the back of her throat and she almost choked, but still there was nothing she could do.
Catherine both saw and felt his hands grab onto either side of her head. He pulled her up, driving his throbbing member deeper into her mouth. Catherine's eyes welled up with tears as the man began pumping faster, fucking her face with his cock. She almost gagged as it hit the back of her throat over and over but the man kept fucking her anyway, never stopping his primal thrusts.
Suddenly she felt the hands on her head squeeze hard as he came in her mouth. His cock pulsed as hot, sticky loads of come spurted out and shot against the back of her throat. She could feel her mouth fill up with a monstrous amount of semen, pooling in the back of her throat and bulging out her cheeks.
When he was finished coming the man pulled his cock, still hard, out of her mouth and looked down at her. The come was pooled in her mouth as she lay there. She tried to spit it out but couldn't. It was all she could taste, the bitter-salty mixture of a stranger's semen.
She felt him place one hand on the top of her head and one hand on the base of her throat, cupping over it. The man then began rubbing his hand up and down her throat, massaging it, causing her esophagus to relax and open up.
Catherine's eyes widened in protest as she felt his warm semen run like a river down her throat and into her belly, all without her control. She could only lie, frozen, as this man took complete control of her body.
After all of his come was gone he took his hands away and stepped back. He pulled his cock back up into his pants and fastened them, reaching down beside him to a large cylinder sitting on the floor beside him. He grabbed the top of the cylinder and turned it, then turned away from Catherine and began busying himself at the table on the opposite wall.
Catherine watched, her vision slowly becoming clearer, as the room around her began filling in with detail. The edges of the walls began to appear, shelving started to come into focus, and Catherine could hear ...
~~~
... the sounds of children playing outside in the waiting room.
Catherine blinked her eyes and saw the ceiling tiles above her, the glaring light of the fluorescent bulbs shining illuminating the room. She realized that her mouth was still open and she slowly closed it, her jaw feeling creaky. She ran her tongue around in her mouth and felt a strange coated feeling inside of it. She tried to get rid of the
feeling, but it stayed where it was.
Doctor Thorn turned around from the table on the opposite wall when he heard Catherine smacking her lips.
"Ah, awake now, are we?" he asked, smiling. "How was that? Did you feel anything?"
"N-no," Catherine said, "but I ... my mouth tastes weird. Like it's coated with something."
"Oh yes, that's just some of the wash that I used while cleaning your teeth. Here, you can rinse it out with some water."
He poured some water into a small paper cup and gave it to Catherine. She rinsed and spat into the basin beside her, Doctor Thorn picking up a clipboard from the table behind him.
"Well, things are looking better, Catherine, but I'm afraid I wasn't quite able to get all the work done that I needed to do. Are you able to come in tomorrow at around the same time?"
"Um, yes, I suppose so," Catherine said, her mouth still feeling gross. "What other work do you need to do?"
"Oh, mostly just taking care of some things I wasn't able to get to today," Doctor Thorn said with a smile. "It's all technical jargon, I don't want to bore you. Anyway, be sure to make an appointment with the receptionist at the desk and I'll see you in a few days, all right? Okay!"
He turned his back to Catherine and began fiddling with something on the table again. Catherine got up out of the chair and grabbed her purse as she headed for the door.
"Good bye doctor," she said.
Doctor Thorn raised a hand briefly in farewell, not turning around to look at her. Catherine walked out of the examination room and back to the receptionist's desk where she made her next appointment. She left the office feeling unsteady on her feet and with that taste still coating her mouth.
