M is for...: A standalone medical-themed romance (Checklist Book 13)

by L. DuBois

  He glanced at her hands, checking for a safe word symbol, but her hands were in loose fists.

  Zidan walked around to the foot of the table, caressing her shin as he did. She made a soft little sound every time he touched her—a sigh, a quick inhale, even the occasional happy moan. He wondered if she realized that even when he was hurting her, she was telegraphing her enjoyment.

  And he was hurting her.

  And he enjoyed it…because she wanted it. Needed it.

  Zidan put his foot on the base of the round black stool and rolled it into place. He hadn’t known Las Palmas had what amounted to enough medical equipment to outfit an actual exam room. Everything from the stool to the table had been purchased from a real medical supply store.

  The wheels of the stool clattered, and Cali lifted her head. He doubted she could see the low stool, but when he sat it was more than clear what had made the noise.

  Cali’s face screwed up, and her upper chest and cheeks flushed mottled pink and red with embarrassment.

  Zidan checked the urge to comfort her, to once more remind her of her safe word. She was an experienced sub, and he trusted her. The fact that he was her top meant there was some added emotional impact to the scene, but he was working hard to be just “Master Z” not Zidan.

  Not the man who was technically her husband. Not the man who’d made terrible mistakes. The man whose past meant that though he wanted to love her, he couldn’t.

  Zidan closed his eyes for a moment, and when he opened them again he was Master Z.

  And Master Z had a slave to examine.

  Master Z sat down between her forcibly spread legs. Hot embarrassment prickled at her skin and Cali closed her eyes.

  It felt like she was at the gyno. Like she was about to have a pap smear or her IUD replaced. Neither one of those things was sexy. They were embarrassing and uncomfortable.

  The embarrassment and discomfort were there, but she was also aroused, and the dissonance between those feelings was like hearing a familiar song played badly.

  “You do have a lovely cunt.”

  Cali opened her eyes, debated if she wanted to make an issue of it, then raised her head, glaring at him.

  Master Z quirked a brow. “Don’t like that word?”

  She shook her head once.

  “Well then…that is unfortunate, because this is your master’s cunt.” He patted her vulva. “And that means he, and I, can call it whatever we want.”

  Cali deepened her frown, but she turned her head away, unable to defy him when confronted with his calm dominance.

  Master Z smirked. “I can see exactly how wet your pretty cunt is.”

  Cali dropped her head back onto the raised upper half of the exam table.

  “You’re so wet that your anus is nicely lubed, though I will use some additional lube when I open up your ass.”

  She couldn’t stop the strangled sound of fear and arousal that escaped through her open mouth.

  “Don’t worry, I intend to examine your cunt first.”

  The word sounded soft when he said it this time, instead of hard and accusatory.

  His gloved fingers stroked her labia, firm but gentle touches. Cali tried to stay still, but she was so damn aroused, patience and obedience seemed impossible. When the repetitive up and down motion brought his finger back to the top of her pussy, Cali tilted her hips with a quick jerk. Her clit moved into the path of his finger.

  Two fingers brushed over the tip of her clit and Cali’s whole body jolted. The pleasure was focused and intense, but also a relief, as if it had released some of the pressure inside her.

  His hands lifted from her skin, and Cali didn’t dare look at him.

  She shouldn’t have done it…and yet she didn’t regret it. That didn’t mean she wanted to see Master Z’s expression and face the consequences until she had to.

  After a long, silent moment, fingers brushed her pussy once more. She braced herself, expecting pain, but instead he pinched her labia gently, palpating the puffy, slick flesh. There was something clinical about the touch. He methodically worked his way from the bottom up, thumbs gliding along the inner surface while two fingers massaged the outside of her pussy lips.

  When he reached the top—his thumbs resting on the hood of her clit, his fingertips arrayed on the top of her pussy—he pinched and massaged the plump mound of her vulva.

  Then he adjusted his grip so her pussy lips were captured between his bent fingers—the knuckle of his middle finger firmly in the valley of her sex, index and ring fingers along the outer sides of the lips.

  He squeezed his fingers together, compressing her plump labia between his knuckles, and tugged. Cali gasped, the sound lost amid the clank of chain as she yanked on her manacles. She fucking loved having her pussy lips tugged. She didn’t know why, couldn’t identify where this perversion had come from, but the pleasure she got from it, while not as directly stimulating as having her clit or nipples touched, was real and very acute.

  “You cunt is lovely,” Master Z said softly, his voice rough in a way that told her he meant those words. “Nice fat outer pussy lips, and your inner labia like to peek out from between them when they get puffy, even with your legs closed.”

  For a moment she was pulled out of the scene, because Master Z wouldn’t have known that, wouldn’t have known how much she liked having her labia pulled on—but Zidan would.

  “And your clit is lovely too, though well hidden, protected by all this plump flesh.” He went back to massaging the top of her labia, pressing fingertips to thumb and creating small circles. The sides of his thumbs bore down on the base of her clit, almost pinching it. “Not that I will allow you to hide it from me.”

  Cali glanced at Master Z through her lashes, watching him examine her. She was the vulnerable one.

  She was powerless, and yet, for a moment, she felt powerful. He’d imprisoned her with chains and straps, but she’d ensnared him too.

  Then his thumbs squeezed her clit hood and a lance of pain wiped away all thoughts, all feelings except desire-tinged embarrassment and submissive anticipation.

  “Tell me, when I stroke the head of your little octopus, will the legs clench down on your channel?”

  It was rare that any man, even Doms who were far more savvy about women’s bodies than their vanilla counterparts, thought or talked about the clit as anything other than a small bundle of nerves above the vagina—the man in the boat.

  The clitoris was actually more like the octopus he’d just mentioned—the tip, the “head”—the only external part. The “legs” were internal, running down from the head behind and within the pussy lips and around the vaginal canal. That tissue could swell and expand, plumping the labia and tightening the vagina.

  Even knowing this, and being a proponent of anatomical correctness with regards to the female anatomy, Cali rarely thought of her clit as anything more than the bundle of nerves she liked to mash a vibrator against at night.

  “Answer me, slave.”

  The crop appeared from seemingly nowhere and cracked against the inside of her left leg. Cali yelped, and nodded her response.

  “I want to hear you.”

  She stared at him in consternation then tried to say “yes, Sir.” Only the “s” sounds were legible.

  “Excellent. Though I will verify that as part of the exam.”

  Master Z bent his head to her pussy once more. This time he fingered her inner labia, pulling on them, rubbing and then spreading them wide. She felt air against her entrance, and the stimulation from that made her pussy spasm.

  “Ah, lovely. I got to watch some pretty cream slide out of you as you clenched.”

  Cali’s cheeks heated and she turned her face to the side to hide the flush.

  Not that she could hide anything from him. He wouldn’t let her.

  “You find this pleasurable,” Master Z remarked, his head bent low as he examined her. “Being examined like this. Being spread wide.”

  She sh
ook her head, a piece of hair that had escaped the braid sticking to her wet lower lip and tickling her chin.

  “You do. You know exactly how lovely this cunt is. Exactly how desirable you are.” His fingertip teased her entrance.

  Cali held still, checking the desperate urge to raise her hips and force his finger deep into her body. Even the penetration of a single finger would be a relief.

  She didn’t move, not just because she feared a reprimanding strike from the crop, but because she wanted to be obedient. There was a freedom in that. In relaxing into trust—trust in a Dom, in the lifestyle.

  Master Z pulled away, and this time she didn’t raise her head to watch him go. When he returned—she heard the scuff of his shoes, the sound of the wheels on the rolling doctor’s stool—she remained still and patient. A good slave waiting for her next order, waiting to be used.

  Her nipples tightened at the thought, and when he set something on her belly she finally raised her head, no longer caring if she drooled all over herself.

  A phone was propped on her stomach, balanced on the unattractive flesh roll. She glanced from it to Master Z.

  He waited until she was looking at him and then raised a small dildo. Or maybe it was a plug. Only four or five inches long with curvy, undulating sides. The base was a silver disk with a small wire protruding from it.

  “This is meant to help women practice their Kegels—strengthen the pelvic floor. But that’s not how we’re going to use it.” Master Z swiped two fingers through her pussy, raised them to show how they glistened in the light, and then started lubing the dildo. “I’m going to use it to test different methods of clit stimulation.”

  Cali sucked in air in shock.

  Master Z smiled, that dangerous half smile, and looked at her through his dark lashes. “You might enjoy it. You might find it…overwhelming.”

  Cali whimpered and then tried to say, “My clit is sensitive,” but the words were, of course, garbled.

  Master Z scooped up more of her body’s lubrication, applying it to the dildo before using that same hand to spread her labia open.

  “Relax,” he said in a cool, calm voice.

  In that moment he sounded like a doctor, a detached medical professional, and her cheeks burned.

  The small pressure sensor dildo touched the entrance to her vagina and the burn of humiliation intensified, because this time she couldn’t stop herself from raising her hips a little, showing off exactly how wanton she was.

  Master Z pressed the dildo into her. It was slender—far smaller around than a cock—but it seemed to fill her, forcing the walls of her vagina to yield, to open.

  By the time he stopped pushing she was panting, her nipples diamond hard, and her tongue coming out to wet her dry upper lip, but staying to stroke the sensitive flesh there, imaging it was not her tongue, but his.

  “I shouldn’t need to tell you this, but for fairness I will.” Master Z tapped two fingers against her vulva. “You are not allowed to come.”

  Cali nodded. There was no way she could actually obey that order, not if he planned to play with her clit. This was a tried and true game—a Dom ordered a sub not to come, made sure she orgasmed, and then punished her for it.

  At least that’s what she expected to happen.

  Instead, Master Z reached under her leg and grabbed the rolling tray, drawing it closer. Then he grabbed a slender metal tool, holding it up for her to see. A slender metal rod with one end slightly pointed, the other blunt and rounded—almost like a knitting needle or a crochet hook without the cut out “hook” part.

  Master Z smiled at her, a casual, impersonal smile. “This may hurt.”

  Chapter 5

  Master Z patted her vulva with the hand not holding the slim metal tool. Comforting her after threatening…promising…to hurt her.

  “If pain applied to your clit means your cunt will clamp down hard on your master’s cock, which I will know thanks to the little device in your cunt, then I will advise him in the best ways to abuse your clit to increase his own pleasure.”

  Cali blinked hard, tears sliding down her cheek, though she wasn’t sure why she was crying.

  Master Z didn’t seem to notice. He picked up his phone and tapped the screen a few times. “We need a baseline. Clench down on the dildo.”

  Embarrassment turned to fiery humiliation, and another tear escaped. Cali sniffed. Having her nose start running because she was crying when she was helpless to wipe away the snot would be icing on the humiliation cake.

  “I said clench, slave,” Master Z barked.

  Cali sobbed, closed her eyes, and then tightened her vagina around the dildo.

  “Again,” he ordered.

  She clenched down, and this time the dildo started to slide out. Master Z shoved it back in, and a spike of pleasure cut through the humiliation. Her eyes popped open and she moaned.

  “Ahh, that’s lovely.” Master Z turned his phone, showing her a line graph with three spikes—the times she’d deliberately clenched, and then when the dildo thrust in and her body had clamped down on it.

  “Now, to test your pretty clit, Princess.”

  Master Z brought the metal tool down between her legs. Cali couldn’t see exactly what he was doing, even when she lifted her head and craned her neck. What she could see was Master Z’s head bent low, less than a foot from her pussy. She could see his hand, the metal rod he held like a pencil between his fingers.

  Something brushed her clit. Not the sensitive hood, but the slightly pointed tip that was no doubt peeking out thanks to her arousal.

  Her nerve endings registered sensation—just sensation, beyond the definition of pain or pleasure. It felt as if he touched her with a live wire, causing her body to arch and muscles to clench.

  Then he did it again.

  Her body arched up, her heels digging into the stirrups, which felt like they gave a little—these things weren’t meant to take this kind of force.

  His phone fell off her belly onto the exam table, unnoticed. Unimportant.

  She bit down on the spider gag, the metal digging painfully into the roof of her mouth, her teeth aching.

  “I was touching your clit itself, not the hood,” Master Z said when she crashed back onto the exam table.

  Externally, Cali whimpered, her legs trembling with little flutters of muscle movement.

  Master Z pushed the dildo deeper into her. “If this falls out you’ll be punished.”

  Cali widened her eyes at him. She was so wet that she doubted the dildo would stay in if he let go.

  But he did let go, and then rose from his stool, coming to the head of the table. She watched him, anticipatory, aroused, and yes, a little scared.

  Master Z grabbed the sides of the spider gag, and pulled it out of her mouth. The strap dug into the back of her neck, but it gave enough that he slid it down over her chin to dangle around her neck like some macabre necklace.

  Cali closed her mouth in relief, running her tongue all around her teeth and lips, probing the sensative spots where the O-ring had dug in. She wondered vaguely if the inside of a mouth could bruise.

  Master Z swiped his thumb across her lips once, twice. Cali kept her eyes closed. He ran his thumb over her mouth again, more slowly.

  She didn’t want to part her lips, she wanted to enjoy this moment of relief from bondage. From being controlled.

  Master Z gently pinched her lower lip, a small warning. Then he ran his thumb over her mouth again.

  This time her lips parted, teeth opened, and when he pressed his thumb into her mouth, she sucked obediently.

  “Good slave,” he murmured as he withdrew his thumb.

  Cali’s cheeks heated with embarrassment, and her muscles tightened.

  And the dildo started to slide out of her slick passage.

  Cali’s eyes popped open and she looked up at Master Z. He raised a brow, then leaned to glance at her pussy.

  “You’re perilously close to having your feet whipped, slave.
”

  Cali licked her lips and her voice was hoarse when she spoke. “Master Z, I’m trying not to let it slide but I can’t…”

  “Your cunt is too wet, and your response to your exam too intense.” Master Z reached between her legs and casually shoved the dildo back into her pussy.

  The fullness, the pressure of something inside her, even if it was too small to be really satisfying, was both pleasure and relief.

  “Time to continue with the exam.” Master Z resumed his seat and picked up something from the tray, holding it up for her to see.

  A toothbrush.

  Black with white bristles, it was simple—disposable even, just a straight plastic handle and even, white bristles.

  “You’re not going to—” Cali clamped her lips together to stop the rest of her words when Master Z shot her a cold look.

  “I will do whatever I want to you.” The utter command in his voice made her go limp. Normal people would have tensed, or tried to get away.

  But Cali was fully engaged in the scene, feeling deeply submissive. And a good submissive knew that when faced with a less-than-pleased Dom, the best response was to go limp if in bondage, or kneel if free.

  “Of course, Master Z. I want to please my master, and you.”

  He grunted. “Very good, slave. But I won’t forget your objection.”

  Master Z withdrew the dildo completely, and Cali tensed. Had she completely failed this “test”?

  He set the dildo on her belly beside his phone—which he’d put back in place—and then his fingers slipped between her legs, toying with her labia, with all the skin that he’d so carefully examined.

  “You deserve a little reward.” Master Z’s voice was husky.

  She could have pointed out that he’d just said he wouldn’t forget that she’d protested. As Cali looked into Master Z’s face, she knew that his fingers leisurely stroking her pussy had far more to do with his need than with the exam he was performing.

  She remembered when Zidan had looked at her like that.

  Master Z thrust one finger into her pussy and it was exactly what she needed to stay in the moment and not drift into the past. His finger curled inside her, hitting her g-spot, and a wave of soft pleasure swept over her. It was almost a relief after the intensity of feeling caused by the probe against her clit.
