Cash cut the ignition and peered up apprehensively through his windshield at the shining glass office building. “Omega Fertility Specialists of Silver Grove” was emblazoned on the side in big block letters, proclaiming to one and all the purpose of any who entered.

“Ok, Cash,” he muttered to himself. “You can do this. It’s just a check up. Nothing scary.” Dealing with a lifetime phobia of doctors wasn’t going to be easy, but this would be worth it. It had to be.

Taking a deep breath, he crossed the parking lot, the wind whipping playfully at his long dark hair, and entered through a revolving door. The lobby was elegantly bare, with gleaming tile floors and a few potted plants. A silver-haired man, older but still thick with muscles, watched him approach from behind a desk marked “Security.”

“You have an appointment today?” he asked, sizing up Cash over dark-rimmed glasses.

Cash nodded timidly. “Checkup with Doctor Moore, for 3:00?” he replied, unable to keep the shake out of his voice.

The security guard glanced down at his laptop, then nodded. “Fourth floor. Go on up.”

Cash rode up in the shiny chrome elevator, the reflective walls mirroring his apprehensive face, until the doors slid open with a soft chime. In his hurry, he almost walked directly into a couple waiting to board the elevator, the smaller of the two men cradling a baby swaddled in a blue blanket.

“Oh! I’m sorry,” he said, as the couple stepped aside to allow him to pass. Cash hoped the jealousy he felt wasn’t visible on his face as he smiled down at the tiny bundle nestled in the man’s arms. “Your baby is so adorable.”

“Aww, thank you,” chirped the Omega, his Alpha giving Cash a warm smile. “Doctor Moore is the best, you’ll see.” The couple boarded the elevator and disappeared behind the sliding chrome door, but the sight of them had given Cash some renewed determination. Taking a deep breath, he turned and opened the door to Dr. Moore’s office.

A pretty red-haired receptionist in forest green scrubs looked up from her computer as he entered. “Welcome! You must be Cash, for your three o’ clock,” she said. “It’s your first time here, isn’t it?”

He nodded, wiping his palms on his jeans as he crossed the waiting room. “That’s right,” he answered, trying to sound braver than he felt. She slid open the window and handed him a pile of paperwork, informing him that someone would be up shortly. Cash sank down onto a plush leather chair and busied himself with recalling his medical history and insurance information.

As he worked, the Omega got the uncomfortable sensation he was being watched. He glanced up, meeting the eyes of a stunning blonde woman across the waiting room. She was clearly an Alpha: her perfect posture, immaculately-tailored business suit and killer stiletto heels radiated a powerful sensuality. Still watching Cash, she took a deep breath, the slow rise and fall of her chest visible from across the room, and flashed him a predatory smile. He hastily dropped his gaze and bent back over his papers, cheeks reddening with embarrassment.

Cash was in the early stages of his heat cycle, which meant that he was giving off pheromones that would advertise his fertility to any Alpha in sniffing distance; clearly, she’d picked up on it. Of course, this wasn’t like the old days: nobody was going to drag him off by the hair and have their way with him. But it was still humiliating to know that she knew.

“Cash? We’re ready for you,” someone said, interrupting his thoughts. He glanced up to see a matronly-looking nurse smiling at him. “Come on back,” she urged. Grateful to escape the Alpha female’s predatory gaze, he followed the nurse back into the exam room area. She weighed and measured him, recording the results on his chart, before escorting him back into a small private room.

“All right, all your paperwork seems to be in order,” the nurse said. “If you’ll remove your clothing and climb up on the exam table there, the doctor will be right with you.”

Cash blinked. “Remove my clothes? All of them?”

“That’s right, dear. You can cover yourself with that paper sheet if you’re shy.” With a wink, she closed the door, leaving Cash alone.

He frowned, but obeyed, folding his jeans and t-shirt on a nearby chair and slipping his boxers between them, shivering as the cool air of the room hit his bare skin. After kicking off his shoes and socks, he climbed up on the table, feeling the paper crinkle beneath him. He found the sheet the nurse had mentioned and slid it protectively over his lap.

The examination table was as big as a twin bed, making Cash feel even smaller than his five feet zero inches. He swung his legs as he looked around, trying to breathe normally, to keep calm. The walls held a series of framed diplomas and awards, a diagram of the complex male Omega reproductive system, and an advertisement for a new fertility drug featuring a picture of another happy family.

A knock on the door made him jump, and it swung open, admitting a man so gorgeous Cash was glad for the sheet over his lap.

The doctor was tall and broad-shouldered, with auburn hair and storm-grey eyes behind stylish glasses. He smiled. “You must be Cash. I’m Doctor Moore. What brings you in today?” As he spoke, the doctor pulled the door closed and flipped the lock. Cash could hear the deadbolt sliding in to place with a soft click. Was that normal? Must be so they would have privacy.

“Well, Doctor, I want to have a pup of my own. So I thought I’d get a pre-pregnancy checkup.”

The doctor nodded, flipping through some papers on his clipboard. “A very smart move on your part, Cash. It says in your paperwork that you’ve never carried before, correct?”

“That’s right.”

“And have you discussed this with your partner?”

Cash flushed, twisting the paper sheet between his fingers. “I actually don’t have one. I was thinking about using a... service.” There were breeding agencies that matched Alphas and Omegas for a heat cycle, if one of the participants wanted a child but no mating commitment. They ran the spectrum from super-shady to incredibly expensive, depending on the clientele.

He could see the doctor arch an eyebrow, a small smile on his lips. “Well, that’s always an option. We can recommend a few reputable agencies for you, if you choose to go that route. But for now, let’s get you checked out.” The doctor set the clip board down on the counter and produced a small flashlight. When he moved closer, Cal caught the doctor’s scent, so delicious it made his toes curl. Smoky, earthy, like a forest in autumn. Totally sexy. Definitely Alpha. Yeah, the sheet over his lap was the only thing saving him from total embarrassment.

Doctor Moore reached forward, catching hold of Cash’s chin with cool fingertips and tilting it up. “I’m just going to check your vitals,” he murmured, gazing into Cash’s eyes. “Pupils dilated, common for fertile Omegas,” the doctor said.

Cash bit his lower lip as the doctor slid his fingertips down the side of his neck. Dr. Moore glanced down at a thick silver watch. “Mm, your pulse rate is slightly elevated, but that’s normal for the beginning of a heat cycle. Let’s check your temperature.” The doctor produced a thermometer from the pocket of his white coat. “Open your mouth, Cash,” he said softly.

The Omega shivered. What was it about the way the doctor said his name that was so hot? He obeyed, parting his lips. The doctor shone his light down Cash’s throat appraisingly for a moment before sliding the cold metal of the thermometer under his tongue. It beeped a few seconds later, and Doctor Moore removed it gently from between Cash’s lips.

“Ninety nine point five,” the doctor announced, making a note on his chart. “Yes, definitely in the early stages of heat.” He smiled, and Cash blushed, dropping his gaze. “Now then,” the doctor said, “I’m going to continue the examination to make sure your body is ready for mating and carrying. Lie down on your back, please.”

Cash obeyed, the paper that covered the examination table crinkling under his bare skin. He gazed up at the fluorescent lights embedded in the ceiling, trying to slow his pounding heart. God, he was so nervous. His phobia was coming back with a vengeance, and he wasn’t sure he would be able to handle this part. The fact that Dr. Moore was so damn hot made it even worse, somehow.

As he looked steadily up at the ceiling, the Omega suddenly felt the paper sheet being lifted off his lap; the only thing keeping him from being totally naked in front of the doctor. He bolted upright, making an instinctive grab to keep it in place. “Please, doctor,I can’t...” he stammered.

Dr. Moore laughed softly, leaning over him. “Cash, I’m going to need to remove this to examine you properly,” he said, with a kind smile. “Don’t worry, I’m a doctor, I’ve seen it all. And I have to say, you’re a gorgeous, young, fertile Omega, you have absolutely nothing to be embarrassed about. Now, you want me to make sure you’re ready to have a pup, don’t you?”

“Yes,” whispered Cash, sure that he was bright-red with humiliation.

The doctor continued to smile down at him, but Cash thought he caught a flash of something darker in those grey eyes. “You know, Cash, you might feel better if I strapped you down to the table. Some patients report that being in the restraints helps keep them calm. What do you think?”

Cash nodded, too embarrassed to speak. The doctor bent over him, his Alpha scent overwhelming to Cash’s heat-sensitive nose, as he pulled something over the edge of the table. The Omega felt soft sheepskin envelop his wrist, and then the firm pressure as the doctor cinched the leather cuff tight, buckling it in place with a soft clink of metal. His other wrist was soon shackled as well, pinning him flat on his back, his arms spread to the edges of the exam table. He moved his arms experimentally, but the cuffs held firm, keeping him in place. He bit his lower lip, glancing up at the larger man.

“Better?” asked the doctor.

He nodded, keeping his gaze up to the ceiling to avoid meeting the Alpha’s eyes.

“Very good, Cash. Let’s proceed with the exam.” The Omega squeezed his eyes shut as the doctor pulled the sheet off, revealing Cash’s naked body... including the hard-on he’d been trying to hide ever since the Alpha walked into the room. “Large for an Omega,” the doctor murmured. “Interesting.” Cash didn’t think he’d ever blushed harder in his life. He heard the snap of latex gloves being pulled on, the sound making him bite his lower lip.

“I’m going to examine you now, Cash,” the doctor said, his voice calm and authoritative. “I’m going to need you to relax, and breathe deeply. Can you do that for me?”

“Yes, doctor,” Cash murmured. He had to bite back a moan as he felt the doctor’s large hands close on his cock, stroking slowly up and down. The restraints held him in place, leaving him helpless to resist. 

“Firm erection, a good sign of fertility, even in Omegas,” Doctor Moore murmured. “Pre-seminal fluid looks normal and healthy.” Cash squirmed as the doctor ran a thumb over the head of his cock, smearing the slick fluid across the tip. “Now then, let’s check out your testes.”

Cash couldn’t stop the whimper that escaped his lips as the doctor gently squeezed his balls, rolling them experimentally in his gloved palm. “Easy, Cash,” he purred. “You’re doing so well.” Cash managed to stay quiet as the doctor withdrew his hands. “Well, everything looks healthy so far. Now, I need to do a quick pelvic exam,” the doctor continued. “Let’s get your feet in these stirrups.”

Cash heard the clunk of metal as the doctor extended the metal stirrups, then felt the gentle pressure of the doctor’s fingers closing around each ankle, guiding him to spread his legs wide. He felt incredibly vulnerable, lying naked and bound to the table, everything clearly visible to the doctor’s steady gaze. Being exposed like this was so humiliating... but incredibly arousing as well.

“Normally I would use some lube here, but it seems like your natural production is excellent,” the doctor murmured, with a soft smile. Cash gasped as he felt the doctor’s fingertip pressing experimentally against his tight pucker, swirling in gentle, almost teasing circles. “Any tenderness or pain?”

“No, doctor,” Cash managed, his hips almost lifting off the table of their own accord. He pulled, but the restraints held firm.

“Excellent. Now, I’m going to insert one finger to start, you might feel a little pressure,” the doctor said. Cash’s eyes fluttered closed as the doctor slipped inside him, even one digit feeling amazing in his heat-sensitive state.

“Mm, you’re very tight, Cash. When’s the last time you had sexual intercourse?”

“It’s been... over a year, I think,” Cash mumbled.

The doctor nodded. “And how often do you masturbate?”

Cash was so flustered he could barely respond. “Usually once a day, more when I’m in heat,” he mumbled.

He heard the doctor laugh softly. “There’s nothing to be embarrassed about, Cash. Having a strong sexual drive is normal and healthy. Now then, I’m going to check your prostate. This might feel a little more intense.”

Cash gasped as the doctor curved his finger upwards to press against that sensitive spot deep inside him. The sensation sent a jolt of pleasure surging through him, making him crave more. His cock twitched, arcing up and slapping back down against Cash’s stomach.

“Mm, feels healthy and very responsive,” the doctor said. Cash could swear he heard a slight change in the doctor’s voice, his once calm tone starting to sound rougher, more sinister. “Now, I’m going to need to collect a semen sample from you.” Wait, what? His eyes snapped open. The Omega looked up, alarmed, meeting the doctor’s gaze. The look in the man’s eyes was one of unmistakable lust: the doctor was an Alpha, and Cash was Omega, bound and helpless, to do with what the dominant man pleased.

The doctor continued, his voice still calm, authoritative. “We’ll try a simple digital massage first, and if that doesn’t do the trick, I’ll employ different measures.”

Cash gasped as the doctor slid another finger into his tight asshole, pushing and probing mercilessly. “Oh god, doctor,” he groaned, as pleasure rocketed through him, his hips bucking involuntarily with each press.

“That’s good, Cash,” Doctor Moore murmured, his lips curved into a wicked smile. “Such a good little Omega.”

Cash felt the doctor squeeze his thigh with his free hand, the other working a third finger deep into his ass. He knew this was wrong, so fucked up, but he wanted it desperately, wanted more. He couldn’t escape, so why not give in to it? With each stroke, the doctor expertly found that sweet spot, and soon the pleasure was too much, he couldn’t stand it. With a gasp, Cash shot his load, his cum spurting across his own stomach in little pulses. He bucked and writhed as the orgasm tore through him, but the restraints held him firmly in place. This feeling of total helplessness, of being at the doctor’s mercy, was intoxicating.

“That’s a good boy,” murmured the doctor, continuing to slide in and out of Cash’s slick ass, prolonging his ecstasy. Cash was dimly aware of a small plastic vial being scraped across his stomach, the doctor collecting his sample. Slowly, carefully, the doctor withdrew his fingers.

Cash whimpered at the sudden emptiness, arching his back, tugging at his restraints, desperate to be filled again. “Doctor, please,” he moaned. An Omega in heat could, and often did, fuck for days. The presence of an Alpha had triggered his full heat, and he could feel his logical thoughts receding, driven by only one desire: to be bred by this man.

The Alpha laughed, low in his throat. “Oh, you do need fucking badly, don’t you?” He pulled his gloves off with a snap of latex, tossing them to one side. Cash watched, helpless and unable to move, as the doctor unbuckled his belt, pushing his pants down over his hips. His Alpha cock sprung free, huge and thick, the knot already partially inflated at the base. “Well, I’m going to fuck you and fill you good, but first I want to try out that sweet mouth of yours.”

The doctor crossed to the right side of the table, reached out, and tangled his fingers in Cash’s long hair. With a sharp tug, Cash was forced to turn his head, the massive cock just inches from his face. “Open your mouth, Cash,” the Alpha growled. “Let’s check your temperature one more time.”

Cash barely had time to part his lips before the doctor pushed the head of his cock between them, forcing Cash’s mouth open. He moaned as the doctor slid his thick length into Cash’s eager mouth, the salty-sweet taste of pre-cum flooding over his tongue. Cash wanted to reach up and stroke the doctor’s shaft, cup his balls, but his hands were bound tightly to the table, making him a helpless vessel for the doctor’s pleasure. 

He opened his mouth as wide as possible to accommodate the doctor’s thrusts, each stroke hitting the back of Cash’s throat, the little shock of pain only adding to the pleasure. He gazed up at the doctor, reveling in the pure animalistic lust he saw in the Alpha’s eyes as he plunged into Cash’s mouth again and again. Everything in him wanted to please this man, to give him pleasure; anything to get the fucking he so desperately needed. His hole was feeling painfully empty, and he was so wet with slick it was soaking the table beneath him.

“That’s good, Cash,” rasped the doctor, as he slowly pulled out of the Omega’s mouth. “But I don’t want to waste my cum in your mouth when I’m going to flood that sweet ass with it instead. Let’s finish the procedure.”

He moved back around to the front of the table where Cash was still spread wide, totally exposed. He heard the doctor breathe in sharply as he stepped up between Cash’s thighs. Strong fingers closed around Cash’s hips, giving him a hard tug, pulling his body down to the edge of the examination table.

Cash gasped as he felt the head of the doctor’s cock press against his tight hole. The doctor was the biggest Alpha he’d been with by far, and wasn’t sure that he’d be able to take all of him in. But he was wet and ready from the doctor’s earlier exam, and he wanted to please the Alpha desperately.

As if reading his thoughts, the doctor pushed inside him with one smooth, forceful stroke that made Cash cry out. The Alpha’s huge cock filled him and stretched him deliciously, as if they were made to fit together.

“Mmm, so tight,” growled the doctor, his fingertips digging cruelly into Cash’s hips. “And so hot. I can feel how fertile you are, how badly you need me to cum inside you, give you a pup.” He began to thrust in a slow, merciless rhythm, each stroke sending him deep inside Cash. The Omega moaned, feeling the thick knot as it pounded against his opening. With one hard push, the doctor forced his knot inside Cash, stretching him to the limit.

The Omega thrashed against his restraints, his hips bucking up to meet each thrust as the doctor took him, filled him, exactly what his body had been craving. He’d been single for so long, he’d almost forgotten what it was like to be taken by an Alpha when he was in heat. There was nothing like it: skin to skin, stretched, filled, fucked.

Cash could feel the doctor begin to pump faster, feel the knot expand, locking them together. “Are you ready to take all my cum, Cash?” the doctor growled. “Ready for me to knock you up?”

“Yes,” gasped the Omega. “Give it to me!”

The doctor snarled and threw his head back, and Cash could feel the hot spurts that meant the Alpha was coming, filling the Omega up with his potent seed. It seemed to go on forever, the knot keeping it all deep inside, the better to impregnate Cash’s ready body.

At last, the doctor sighed, smiling down at Cash. “Would you like me to uncuff you until the knot goes down?”

The Omega nodded, and the doctor carefully bent over him to release his bonds. Slowly, mindful of the knot, the doctor climbed up onto the examination table, pulling Cash to his chest and placing a soft kiss against his neck.

“Rest now,” the doctor whispered, and Cash drifted off to sleep, comforted by the knot that bound them together.
