Author's note: This story has a bit of a slow start. If you want to jump straight to the action, skip to about a third of the way in. Enjoy.

Mark Michaels stood in the early evening gloom, staring up at the soft glow of Kelly’s third-floor apartment window. The light meant she was home and that he would see her for the first time since introducing her to his uncle, Dr. Jacob Michaels, earlier that week. Kelly had been suffering from terrible headaches, and he had recommended she see his uncle for treatment. His uncle was a neurologist—that was true—but what Mark hadn’t told Kelly was that Dr. Michaels specialized in an unorthodox subset of neuroscience, and used methods that would land him in prison if the authorities were ever notified.

Nervous flutters filled Mark’s stomach as he imagined seeing Kelly again after his uncle had had his way with her. Would she look different somehow? Warmer, more amenable, less headstrong? Mark had been in love with Kelly since the moment he’d met her in their freshman sociology class, but she had never seen him as anything more than a friend. He was made painfully aware of that fact any time she blew him off, asked him to help her move without so much as a hug in thanks, or came over to complain about her latest boyfriend.

Mark took care of himself, eating right and going to the gym. He knew he was decent-looking because he’d been propositioned by girls plenty of times in college and had been asked on dates since then. But nothing ever came of it because Kelly was the only girl for him. Too bad she’d been friend-zoning him for going on five years. While he’d put up with it in the hopes she’d one day see him for the worthy man he was, now his wait was over—whether she wanted it to be or not.

Mark knew he couldn’t test out Kelly’s new… malleability until his uncle handed over her reins, so to speak, and that wouldn’t happen until her appointment the next morning, but the urge to see her had been overwhelming. As he climbed the stairs to her apartment, he remembered what his uncle had said to him on the phone earlier that day. “She’s part of my study now, Mark, but after tomorrow, you can use her as you wish whenever she’s outside the walls of my office.”

That had been the deal. His uncle held the command words that would turn her into the woman Mark wanted her to be, and she would continue to visit his uncle’s office as long as the doctor had use for her. Mark’s time with Kelly would be a finder’s fee of sorts, and could end any time his uncle decided. He wished he knew what his uncle planned to use her for, but he hadn’t been forthcoming, and Mark knew not to press him. Uncle Jacob could be scary when he wanted to be.

He rang Kelly’s doorbell and waited, feeling his stomach twist with excitement and apprehension. When the door swung open, he drank in the sight of her. Kelly had big green eyes, a clear, lightly tanned complexion, and waist-length honey blond hair he’d longed to plunge his hands into almost as often as he'd imagined plunging his cock inside her. She had the perfect figure, with a tiny waist, round breasts that jiggled just the right amount when she didn’t wear a bra (such as now), and a firm, plump ass that begged to be slapped. The only thing Mark would’ve changed about her appearance was her height. At five foot nine, she was only an inch shorter than him and often wound up looking down at him when she wore heels, which he despised. Women were meant to look up at men.

Kelly’s full lips pressed into an annoyed pout when she saw him. “Mark, I told you on the phone, I’m too busy to hang out right now.”

He fought to keep smiling, though he felt a pulse of pure rage at her rude dismissal. “I know, Kel, sorry. It’s just that I haven’t seen you since your appointment with my uncle and wanted to ask how it went.”

“That’s private medical stuff,” she grumbled, then relented, opening the door wider and motioning him into the apartment. “You can only stay for a few minutes. I’ve got an early morning tomorrow.”

Mark knew her early morning was the follow-up appointment with his uncle, but didn’t let on. “Okay, no problem. So, how did it go? How are the headaches?”

A blank look came over her face and she gazed into the distance, as if remembering. “It went great. Your uncle is a genius and has such a wonderful bedside manner. I felt comfortable with him right away.”

“Oh, cool,” Mark said distractedly as he stared at her chest. Her nipples had hardened as she spoke, their stiff peaks clearly visible through the thin white tank top she wore. “What did he do to treat you? Medication, or something?”

“Oh, no,” she said, still staring at nothing. A flush had risen in her cheeks. “His methods are much more involved than simple medication. He was very thorough and hands-on in his approach, and I feel like a new woman. I’m lucky to have him as my doctor.”

“Um… okay.” Mark felt himself growing hard at the clear evidence of his uncle’s manipulation of Kelly’s mind. She was having a subconscious response to whatever had happened during her appointment. It was the first solid proof Mark had ever seen of his uncle’s boasts, and it meant she would be his soon. His to use or punish, however he wished, for the poor treatment she’d given him over the years. Maybe Kelly had never seen him as a viable boyfriend, but he was about to become the center of her goddamned world.

At his words, she seemed to snap out of her trance, and her annoyance returned. She rolled her eyes at him and pointed to the door. “Since I can see you didn’t even think to bring me a snack or dessert or anything, you should go. Like I said, I have an early morning.”

He smiled sheepishly and let her lead him to the door. “Sure, sorry to bother you, Kel. Next time I’ll come prepared.”

As he slipped back out into the full dark of night, Mark’s smile became a sneer of anticipation. Come tomorrow, Kelly would learn her proper place, and he’d be the one to put her in it.

*****

Mark arrived at his uncle’s office the next morning at seven forty-five, as directed. The waiting room was empty and the girl behind the counter waved him through as soon as he gave his name. He couldn’t help but noticing how beautiful the receptionist was, as was the nurse who met him as he walked through the door into the back offices and led him to his uncle’s office.

She wore an old-fashioned nurse’s uniform, complete white stockings and a white winged hat, though the skirt was so short he could see the curve of her ass cheeks as she twitched her way down the hallway in front of him, and her obviously augmented breasts strained the buttons of the uniform top. She was the right height for a woman and had to tilt her chin up to look at him. Instead of glaring like most women did when they caught him staring at their tits, her crimson lips curved into a lascivious grin and she winked.

“Mark!” called his uncle from the office. “Come in, my boy!” The vision in white polyester patted Mark’s cheek and strode away, leaving them to their appointment.

Mark entered the office and took a seat before his uncle’s dark wood desk. “That girl,” he said. “The nurse? Is she…”

“Under my control? Of course.” His uncle was blandly handsome and in good shape for a man in his early fifties. He wore wire-rimmed spectacles that he liked to take off and clean when he was thinking, a habit that annoyed the hell out of Mark. “Nurse Tabitha is fully mine, as is every employee and patient in my practice.”

“Um… cool.” Mark shifted nervously in his seat, staring at the framed diplomas on the wall behind his uncle.

“I can see you’re apprehensive, Mark, but you have nothing to be nervous about. Kelly will be here in a little under fifteen minutes, and I will hand you the keys to her kingdom, as agreed. I do insist you stay in the office today for your first encounter. It is imperative you learn the ins and outs of my methods before you leave with her, so you don’t interfere with her training.”

Mark’s eyes snapped to his uncle. “Here? I’m supposed to… be with her here?”

“Just for today. Once I’m convinced you understand my method, you’ll be free to leave.”

“Okay.” Mark didn’t like it, but knew there was nothing he could do about it. This was his uncle’s show; he was just along for the ride.

Uncle Jacob half-stood behind his desk and peered at Mark’s lap. “Goodness, you’re already rock hard! You need to pace yourself if you’re going to be in any shape to break in Ms. Porter.” He grinned. “Though you are young and possess quick recovery time, I’m sure. If you’d like, Nurse Tabitha can come in and service you before Ms. Porter arrives, so that you’re able to last longer with her.”

“Service me? I—uh—I think I’ll wait for Kelly,” Mark finished lamely, his cheeks flaming. But he couldn’t help imaging the nurse in the short skirt wrapping her crimson lips around his cock and sucking him till he blew his load down her throat. The fantasy was not helping calm the bulge in his pants. If he wasn’t careful, he’d shoot into his pants and wouldn’t be able to play with Kelly when she arrived.

In a panic, Mark banished thoughts of Nurse Tabitha and began flexing his thigh muscles while thinking of every gross turnoff he could. It worked. His erection softened, then disappeared completely.

“Before Ms. Porter arrives, allow me to tell you the ground rules for engaging with her. Her initiation phrase, which switches her from autonomous mode to standby mode, is ‘1-9-2-0. A woman needs a man like a fish needs a bicycle.’ It’s my little joke, you see?” When Mark shrugged, the doctor sighed and continued. “Then she will return the phrase, and a choice will need to be made.

“Ms. Porter currently has three persona settings built into her subconscious: loving girlfriend, enthusiastic slut, and reluctant bitch. Each can be cathartic in their own way, and you may switch between them as you go, though I ask that you enjoy each setting for at least a half hour before switching. Too many psyche changes in a short amount of time can be taxing on the subject and may put her into a defensive sleep mode. Though, that can be fun too—my very own twist on the Sleeping Beauty fairytale!”

Mark’s eyes widened as his uncle laughed, and he wondered, not for the first time, if the man sitting before him was entirely sane.

“After I’ve had another six months or so,” Dr. Michaels continued, “she’ll contain at least six settings, each more nuanced than the three she contains now. But I assure you, she can make all your wildest fantasies come true as she is today.”

“Great,” Mark said. “What do I do to pick a setting?”

“Simple. For loving girlfriend, simply say, ‘pink and purple.’ For enthusiastic slut, say, ‘blue and green.’ For reluctant bitch, say, ‘red and black.’ No matter which setting you choose, she will be unable to refuse anything you ask of her.”

“Anything?” Mark breathed.

“Indeed. Except, of course, the commission of certain crimes, namely serious assault and murder. You could order Ms. Porter to spank my beautiful nurse until she weeps for mercy, but you could not force her to cut Tabitha’s throat or chop off her fingers.”

Mark’s mind raced as he tried to banish that horrifying mental image and decide which version of Kelly he wanted to be with for the first time. He adored her, worshipped her, but he was also angry with her and had been for a long time. Before he could be the man she deserved, he had to be the man she needed, the man who could bring her to heel and teach her a harsh lesson for all the years she’d tormented him and treated him like the help. Worse, she’d treated him like a eunuch, a man without needs or wants or dreams of his own. He planned to disabuse her of that notion thoroughly.

“When you’re finished playing and wish to return Ms. Porter to herself, say, ‘Men are afraid women will laugh at them.’ She will remember nothing of your encounter.”

“What if I want her to remember?” Mark asked.

His uncle tapped a finger on his chin in thought. “Well, now, if you want her to actively remember a punishment or lesson, I see no reason why not. She can do nothing to protect herself, after all. You may also impart lessons subliminally, such as an urge to always refer to you as ‘sir’ or ‘master’, or to assume a certain position whenever you walk into a room with her. That’s a popular one among my clients. People can be so creative. One of my favorites is a man who made his wife forget how to dress herself. She would remain naked unless he aided her, often after hours of begging.”

Mark smiled in anticipation and glanced at the clock. Kelly would be here any minute.
“Is there anything I can’t do?” Mark asked. “Like… sex-wise?”

His uncle smiled. “You wish to follow the rules and avoid upsetting me. Smart boy. No, I see no reason to limit your activities with Ms. Porter. Use her however you’d like.”

Mark’s erection had returned. He sure wished Kelly would hurry up and get there. It was weird having a boner while alone with his creepy uncle. As if he’d summoned her, Kelly tapped on the office door and poked her head in.

“Nurse Tabitha told me to come right in, Dr. Michaels. I hope that’s—” Her green eyes widened and she stared at him, her pink lips pursed in a round “o” of surprise. “Mark! What are you doing here?”

“Please come in, Ms. Porter,” his uncle said, “and I’ll explain my nephew’s presence.”

Kelly looked uncertain, but nodded and took the chair next to Mark. She wore a sheer, sleeveless button-down blouse in the same shade of green as her eyes and a tight khaki skirt with high-heel sandals. Her blond hair was twisted into a thick French braid that coiled down her back almost to the slope of her ass. She wore minimal makeup, just as Mark liked, except for a hint of shimmery eyeshadow and some mascara. The top button of her blouse was undone, and he could just see the upper slope of her breasts.

“My eyes are up here, Mark,” she snapped at him, startling his gaze away from her tits.

“Sorry, Kel. You just look nice today, is all.”

“Why is he here, Dr. Michaels?” she said in an annoyed voice. “This was supposed to be a treatment session for my headaches. Doesn’t this violate HIPPA or something?”

“Mark is here because I have enjoined him to take part in your treatment.”

Kelly’s cheeks flushed in anger. “What? That doesn’t make any sense!”

“My nephew is a good friend to you, Kelly, and wishes to help you overcome your nasty headaches. He’s told me what an important part of your life he is, always helping you when you need it, whether it be fixing things around your apartment, helping with schoolwork, or just lending an ear as you vent about boyfriend problems.”

Kelly turned to Mark, her eyes flashing. “That is so inappropriate, Mark! You make it sound like we’re dating or something. We just hang out together sometimes, nothing more. I want you to leave!”

Mark glared at her, his heart pounding with anger. How dare she? He’d basically devoted five years of his life to her, and she saw him as a toy that could be put away in a drawer when she didn’t need him. Fuck that, he thought. I’ll show her who's a toy.

He looked to his uncle, who nodded, a slight smile on his thin lips.

“You heard me!” Kelly snapped. “Get the hell out of—”

“1-9-2-0! A woman needs a man like a fish needs a bicycle!” Mark shouted.

The words died on Kelly’s lips and her face went blank, all life leaving her eyes as she stared at a spot over Mark’s shoulder. Her skin was still flushed with anger, but as he watched, it faded back to its normal shade. Breath held, Mark reached out and poked Kelly’s cheek with the tip of his finger. She didn’t react.

His uncle was watching him with that same smile. “Make your choice, Mark.”

“Here?” Mark asked. “Now? You expect me to do this in front of you?”

His uncle stood up, smile widening. “Well, me and my nurse. But you’d prefer privacy? Ah, I guess I can understand that. I cannot leave you completely unsupervised, but I can leave you alone in a room with the girl. I have just the place. Follow me.”

“What about her?” Mark asked.

“Ms. Porter, come,” the doctor snapped and Kelly stood, her face still blank. His uncle led them to an examination room with a panel of opaque glass on one wall and a speaker by the door. Dr. Michaels tapped on the glass. “Two-way mirror. I’ll be able to observe and communicate with you through the speaker, if needed, though I doubt I’ll need to advise you. Just relax and have fun.”

Mark’s face twisted. “You’re gonna watch us? I don’t know…”

“This is my life’s work, and the research never stops,” his uncle said, still with that smile. “Take it or leave it, nephew.”

Mark looked at Kelly. She stood in the doorway, stock-still, her arms hanging at her sides, eyes distant. Ready. For him.

“I’ll take it.”

“Very good. Everything you might need is in the drawers of the exam table. Fun stuff. Enjoy.”

His uncle ushered Kelly into the room, then left, shutting the door softly behind him. Mark gazed at her, his dream girl, standing before him with no life in her eyes. A doll for him to play with. He shivered as he approached her.

He’d pondered the three personas on offer and realized he wanted all three rolled into one. A loving girlfriend, an enthusiastic slut, and a reluctant bitch. But if he had to choose one now, after how Kelly had spoken to him in his uncle’s office, how she’d treated him for years, he knew what he wanted. He could practically taste it.

“Red and black,” he said.

Kelly snapped to life and glared at him. “What the fuck, Mark? You shouldn’t be here. Leave!”

“Shut up,” he said and her mouth snapped shut, her green eyes widening with indignation. “When I ask you a question or give you an order, you will respond, ‘Yes, sir.’ Do you understand?”

“Yes, sir,” she gritted through her teeth, then blushed. “I don’t know what’s going on here, but you need to—”

“Take off your shirt, skirt, and heels and come stand by the exam table over here.”

“Yes, sir,” she said immediately, and her blush deepened. “If you think I’m going to take my clothes off, you’ve got another thing coming, you sick fuck.” But her fingers were already working at the buttons of her blouse. She looked down in horror as she finished with the buttons and skimmed her blouse off, then unzipped the skirt and let it pool around her ankles. She wore a plain white cotton bra and a red cotton thong. Obviously not underwear she’d been expecting to be seen in. Finally, she took off her heels and stood barefoot on the cold exam room floor.

“Come here, Kelly,” he said, his voice breathy.

“Yes, sir.” She stepped out of her skirt and walked to him. He couldn’t help but laugh at her expression of outraged disbelief as she followed his orders.

“God, you’re beautiful.” He put his hands on her breasts, gave them a firm squeeze. She gasped and slapped his hands away.

“Don’t touch me! How dare you?”

He felt his eyes blaze. “How dare I? How dare you! I’ve done everything for you for five years, and you treat me like a dog. A simpering little lapdog that’ll do whatever you want, no matter how badly you treat it. Well, I’m a man, Kelly, and I’m gonna show you how to treat a man. How to behave for your man.”

“How to behave? You’re crazy!” Her breasts heaved, straining against the thin cotton bra. “You’re not a man, you’re a—”

“If you can’t shut up, I’ll make you shut up. Take off your bra and thong, then leave your hands at your sides. Now.”

“Yes, sir.” She reached back to unhook the bra, freeing her breasts, then slipped out of her thong. Kelly’s tan lines ended at her more private places, which were pale and untouched by the sun. Her tits were amazing, large but firm, with pink nipples grown hard in the chilly air. Her mound was clean-shaven, just like he’d hoped, her belly taut.
