Sperm Donation Clinic (long and very detailed, breeding, anticipation, cuckhold/cheating, height difference, too tight, rough) – Part 1

Skip to ******* for the sex!
———————
“Well, you do still have options.” The fertility doctor spoke empathetically as she broke the news to Mr. and Mrs. Hayes, that the husband, Joe, had virtually no swimmers in his baby maker. This eclipsed the realization on both of them as to why they’d struggled to get pregnant for the past year, despite being in their twenties. They’d married young, with the dream of creating a family together. That dream was getting ripped out from under them before they’d even gotten the chance to try. The wife, a very small, barely 5 foot woman, tucked a lock of her dark, voluminous hair behind her ear, and tried to breathe through the anxiety building in her. Nadia had always wanted to be a mother, but she’d never anticipated becoming one would be so difficult. Her hand reached out to grip onto her husband’s as the doctor continued.

“Of course, the first thing we’d look at is artificial insemination. Surrogacy is also on the table, though, many prospective parents choose the former due to… financial limitations.” The doctor paused, and Nadia and Joe took a knowing look at one another. They weren’t made of money. Far from it, actually. She was a ballerina, dancing for local shows only, and he was a low level IT Specialist. They had just enough money to be comfortable, and not a lot left over for something as expensive as IVF. The doctor stood up and grabbed a brochure to hand over to the childless couple. “If you’d like to proceed with artificial insemination, we endorse the Vie Clinic. They’re sort of a… one stop hub, where you’re taken through the entire process from sperm donation all the way through birth. From what I’ve heard, they have a near 100 percent conception rate. I’ve also known patients who said they were able to meet their sperm donor before the process began.”

Joe’s eyebrows tugged inward as he flipped through the brochure, feeling some resentful morose at his own genetic makeup for putting them in this situation. He cleared his throat. Maybe there was a bit of insecurity mixed in there too. Something about knowing another man’s sperm would be put up inside of his wife made him angry. Knowing that it was very well their only option for pregnancy, even more so.

The couple left the clinic and drove home in silence. That night, they had an argument about trying out the IVF. Nadia bitterly drank wine afterwards and cried in the living room, until Joe came out of their bedroom and sighed with an apology on his lips. He agreed to let her give it a try. It was the only way they’d ever have a family together.

The door jingled above Nadia as she stepped into the cool breeze of air-conditioned sterility. She approached the front desk of the Soleil Clinic with a bit of a rosy hue in her brown cheeks and a shy smile bloomed on her full lips. That same nervous movement, brushing her hair behind her ear, happened again. Not that it helped much, considering she had bangs. She looked over the horizon of her glasses and bangs alike, and finally spoke. “Hello, we’re here for an appointment. To talk about… um, well… how to get pregnant.”

The receptionist behind the counter gave a friendly chuckle and said they’d come to the right place, and gave the married couple a packet of paperwork to fill out. It was a lengthy process that they’d just barely finished by the time their shared surname was called. After being led back into one of the consult rooms, just as sterile and pristine as the lobby, the woman that had brought them back took a seat and gave them a welcoming smile. It eased Nadia’s nerves a bit, and she relaxed visibly in her chair.

“So,” the doctor began, still warm, “You two have been having some trouble getting pregnant, is that correct?”

“Yes.” They both answered in unison, and Nadia huffed through a bashful smile, her plump lips pulling over her pearly white grin. Anyone looking at the couple could see that she was the one with the better genetics. She had an hourglass figure, with natural tapering from bust to waist, waist to hip, where hers were adorned with soft hip dips (and the stretch marks that she so often complained about). For her job, she actually didn’t have the body type the industry typically wanted to see. Even with a ballerina’s rigorous training schedule, her body was stubborn to survive a famine that wasn’t coming. Child-bearing hips and lower belly, that her genetics wouldn’t give up no matter how many salads she ate or runs she went on. That was what made this sort of a cruel joke to her, that her own genetics were damn near perfect for bearing a child—though she’d never tell Joe. It would just make him insecure. That often cropped up in their marriage through Joe’s jealousy. He knew what he had, and didn’t want to lose it.

“Well you’re both in luck then, because here at Vie Clinic, less than 1 percent of our donation receivers leave our care childless.” The hope sprung back to life in the couple, and a smile dressed Nadia’s lips, one that reached her warm dark eyes. Joe, on the other hand, was still a bit hesitant, and the smile that pushed onto his features was more forced. “So let’s talk about fertilization. Here we offer two types of fertilization. The first is the traditional method of in vitro fertilization. The second is a recently FDA-approved method that harnesses the body’s natural processes to aid in the conception. We can also connect you with a surrogacy program, if that’s the route you’d like to take. Now, have you both given thought to the type of donation procedure you’d like? Or to the type of donor you’re ideally looking for?”

“Well,” Nadia began, clearing her throat, and squeezed her husband’s hand. “Um, we didn’t know there was more than one option. And… I guess, ideally, we’d have a donor that looks like Joey.”

“Oh, yes, of course. It’s a very newly approved procedure, so not many clinics are offering it and even fewer clinicians know about it,” the doctor chuckled, and then leaned forward on her desk. “Well, there are pros and cons to both methods. The IVF requires a lot of fertility treatment for you, Mrs. Hayes, and… it can be painful. It also runs the risk of producing more fetuses than intended, and you may end up with triplets… more. It is a very tried and true method, though.

Alternatively, we have that second method I was telling you about. It’s called instinctive manual insemination, or IMI for short. Many… couples, choose to forego this option.” The doctor paused, taking a glance at Joe. He lifted an eyebrow for her to continue. “Well, it involves using the female reproductive system’s natural framework to… make the magic happen. See, when a woman experiences an intense orgasm, the vagina forcefully pulls the ejaculate into the cervix. When the right moment during ovulation is chosen, and this happens, there’s a near 100 percent possibility of pregnancy. Typically a lack of fertilization in married couples is chalked up to bad timing or… an inadequate activation of that process, in the female’s body.”

Joe’s eyebrows lifted in disbelief, and then he looked away suddenly, huffing and offended. “I do not have trouble pleasing my wife,” he insisted. But the look shared between the doctor and Nadia spoke silently otherwise. The sex wasn’t bad per se, but Nadia couldn’t say she’d ever actually had an orgasm with her husband. She never minded, because she was able to get herself off with the right combination of reading material and toys. Sex with Joe had always been something done more out of necessity and bonding, though she didn’t have the heart to tell him that.

Nadia chewed on her lower lip tenderly, in thought, before gently turning to her husband and near pleading with him. “Honey, let’s just… give it a try. Maybe we can try the IVF first? Maybe we won’t even have to take that route. Right?” she looked to the doctor now, who nodded and gave another sympathetic smile.

“Yes, of course. As long as we have a donor on file who genetically matches your preferences, we can look into IVF first. Though, I will say… if you’re looking for the more budget friendly option, by nature, the IMI method isn’t nearly as expensive.”

As the doctor typed on her computer, occasionally looking over at Joe’s features to plug in appearance information into the search, Nadia dared to ask the question they’d been dreading the most. “How expensive is it, exactly?”

“Typically one treatment costs around fifteen thousand, maybe more, maybe less. Typically more than one treatment is also needed.” Nadia nodded slowly, a breath escaping her, overwhelmed with how impossible this situation was becoming. They couldn’t afford fifteen grand. They both knew that.

“And how much for the other one? The… instinctual one.” Her voice broke around the word. Though the doctor hadn’t quite said it in plain language, Nadia knew what she was suggesting. In plain words, she’d be having sex with her sperm donor… and, apparently having an orgasm with him as well. The thought of sleeping with someone but her husband made her nervous and almost turned off. But, then, with quiet shame… the thought of finally having an orgasm with a man intrigued her in a way that made butterflies erupt in her stomach. The thought of finally having the type of sex she read about in erotica made her heart-rate pick up, and she tried to not act too excited at the expense of Joe’s feelings.

She could have stopped breathing when the doctor answered. “Two thousand dollars.” The choice was glaringly obvious. There was no ultimatum even, it was their only option. She chewed on her lip, and tried to understand the whirlwind of emotions building in her as the doctor continued, now with a sigh of her own. “Unfortunately we… don’t have any IVF candidates that match your husband’s profile. However, we do have one IMI candidate that does. Though, he doesn’t match it completely.” Nadia stared at the doctor with a deer-in-the-headlights look. “Well, firstly… he’s Greek.” Joe panned his disbelieving gaze back over to his wife. Joe, though lighter in complexion, was of hispanic and irish descent. Nadia—some alluring mix of indian, bahamian, and russian. The combination had given her a deep, warm and glowing permanent tan. They’d spoken frequently about how they would raise their children with their heritages. How would that be possible now, when his heritage would be wiped off the board and replaced with Greek instead?

Nadia tilted her head in Joe’s direction as she sighed again, another of what was becoming an endless disappointment of a trip. “Well, let’s hear the rest. I mean… Our baby will still be half of me, honey.” It came out like negotiation, and a nervousness bloomed like butterflies in her belly as the doctor continued.

“Other than that, he’s also got very dark brown curly hair. Great facial structure. Uh, blue eyes, though…” she paused as she scrolled, and then opened her mouth in hesitation before speaking. “Um. He is quite tall though. And, stature wise, very large. Says he worked as an officer in the Navy SEALs up until… January of this year. I don’t know if that’s what you both were wanting to throw into your child’s gene pool…?”

Her heart rate began to thud in her ears as the doctor described the man who would be breeding her. She couldn’t stop the tells in her face of how much the was anticipating this now, and then how guilty she felt about wanting this man… right in front of her husband. From his description alone. She nervously tucked hair behind her ears again, trying to take an easy and collected breath.

Nadia chewed her lip in debate, throwing a worried look over to Joe, who now seemed to be completely seething with jealousy over this. “Baby, it’s our only option,” she whispered pleadingly, trying to find his eyes. “Joey. Joe, look at me, please.” The short, curvy woman tried as she reached out to place her palm against her husband’s face, trying desperately to rationalize the lust she felt as she spoke. “If we want to have a baby, we have to do this. You know we can’t afford the IVF… and this sounds… like it will be less painful too. And less risks. It’s just a one time thing, and then it’s done, and we can forget it ever happened. And we’ll finally have a family.”

There was a long moment of deliberation. Both women in the room were looking to the only man, until he drew in a long inhale, and finally stated, “Fine.” Then, a moment later. “But I don’t want to meet him.”

—–

Nadia was ovulating, and Lukas was… larger than she expected.

When the doctor had told them that he was a large man she expected that to be said in relation to her husband’s 5’10 stature, not… this. As she sat there, nipples puckered up beneath her modest turtle neck from the air conditioning in the room, the woman couldn’t form words. If she had seen this man outside of this clinic, she might have rightly been… afraid of him. They both were going over each other’s demographical charts, as one final means of consent, to give each other the green light, and then the IMI would begin. His stated he was 6’4, 42 and two-hundred-forty pounds.

Nadia’s mind buzzed with the shock of this. The idea of this man fucking her was intimidating, if not scary. He looked like he’d worked in the Navy. Her doe-like brown eyes took a worried coast down his heavy form, and then back up to his defined jawline. She couldn’t meet his eyes, she realized. He was quite attractive. More attractive than any man she’d ever seen before off of tv screens, and certainly more than her husband. So attractive it was intimidating; she thought she was pretty and liked the way she looked, but this man looked like god. That, too, made her nervous—exactly with what she wasn’t sure. The lust she felt for him throughout the intimidation was undeniable, though, as she could feel it pooling up out of her pussy. She shifted nervously against the feeling, crossed one leg over the other, and cleared her throat. Before she could speak, he did instead, though.
His voice surprised her as well. It was deep and husky, but somehow unassuming and gentler than she anticipated it to be. “Lukas. Nice to meet you.”

Nadia nodded slowly, finally getting some sense back into her after a few moments of him staring expectantly at her and her avoiding his eyes. When she finally did look up at them, she noticed he had a fleck of brown within the blue. Not a thought about her husband crossed her mind now, as she introduced herself to this man, who was twice her size. “Nadia. Um…” she paused, not sure if ‘nice to meet you’ was the most appropriate greeting. She huffed nervously then, and took a glance over at the doctor, who’d been watching their entire interaction.

“How… um…” she started, and then glanced back over at Lukas’ massive form. “How is this going to work? I mean… anatomically, I…” But she didn’t really have to say it. He was quite literally twice her size. Though she wouldn’t come out and say it outright, if this was any indication of what she’d be trying to fit inside of her after lunch, she wasn’t sure if it would even be possible. All things considered, she was tiny… everywhere.

The doctor gave her a gentle smile and then explained. “Oh, no worries. You’ll have plenty of lube at your disposal. And we’ll also be giving you each some medication, that will make the entire process go smoother. It’s a bit like viagra, but works to increase lust and relax you at the same time.”
Okay. That made her a bit less nervous. What replaced the nerves was a wandering mind… wondering how he might fuck her. If he would be slow and gentle, let her take her time, or if he’d be rough… She wasn’t used to rough sex by any means. Missionary and doggy were the most she and Joe ever did. Her eyes flickered back to Lukas’ muscles, so bulky you could practically see the years of training that went into them. Then she dared to have an explicit thought, one pulled from an erotica she frequented when she couldn’t get off with Joe. Nadia imagined how his hands might feel around her neck, how his tall form would tower over her in missionary… how she’d probably be able to feel the strength behind his muscles as he choked her. Her heart pounded so hard she could feel it in her belly.
She wondered how hard he might fuck her, and the realization came to her then… This was a man who had not only trained in the most rigorous branch of the military, but stayed working as a SEAL for twenty years. Some gut feeling inside of her told her he wouldn’t have mercy on her; that he probably couldn’t even if he tried. He looked like the type to not know his own strength. His footsteps alone had been so heavy she’d heard him walking halfway down the hall to this conference room. Imagining him using that same strength to thrust into her made her both frightened and intensely horny for it to actually happen.

“Have you… donated before?” she asked Lukas now. Maybe if he had a previous donor she could get an idea of what she was in for. He gave something of an amused half-grin. Even his smile was intoxicating. She felt a tug deep in her abdomen at the sight of it, and a second later her pussy flooded out arousal.

“I haven’t. I just signed up last month. My wife and I… have been having a hard time making ends meet since I left the military. This…” he paused, taking a glance over at the doctor and then sighed, and leaned back in his seat, legs wide-stance. “Well, my wife’s not happy about it, but it’s an easy grand. Well… I’m assuming easy.” As if he realized the innuendo in his words after he spoke them, that same half-grin tugged up his lips and he gazed over at Nadia, holding eye contact.
She nodded. Then realized her mistake. Shook her head and quickly followed up. “I—No, actually. I’ve uh, never been able to have an orgasm before.” A pause. “With a man, I mean.”

He gave a slow nod, as if deliberating, and then the doctor interjected again, with a cheeriness that Nadia couldn’t seem to match, not with knowing how her pussy had been throbbing for Lukas this entire visit, and neither of them were even naked yet. Easy might have been a good word to use if he could turn her on this much, this effortlessly. There was some quiet anxiety in her chest about what she’d tell Joe when she went home in the short layover before the insemination appointment they had scheduled in a few hours. Then a pang of guilt, because this was supposed to be obligatory. She wasn’t supposed to be sitting here having fantasies about it.

“Alright, so if neither of you have any objections then we’ll officially schedule you for your insemination appointment today at… 3PM. Once you’re here just let the receptionist know and we’ll escort you over to our insemination unit in the next building over. There you’ll be able to ask any final questions… and back out if you need to.” Then she paused, stood up, smiled and held open the door for the both of them. “But hopefully you don’t need to.”
——–
Nadia was so nervous now that she skipped lunch, and when Joe noticed this he finally accused her. “What’s wrong?” he asked, and when she didn’t answer, he started making assumptions. “The visit didn’t go well, then?” He said it with concern, but she could see the little bit of triumph sparkle into his eyes. He wanted the visit to go badly. He didn’t want her to be fucking some other man at all, let alone finding that man so attractive she imagined him choking her right there in the appointment room. Nadia didn’t answer, and Joe leaned back in the couch, unable to stop the smug smile that ghosted onto his features. He turned up the volume on the tv, and then remarked. “Well. It’s just one time.” He echoed her words, somehow only now being accepting of them.
She glanced over at her husband, wondering if he might have ever said that if he knew exactly how badly she wanted this to be more than just one time already. Then she wondered if it might ruin their marriage had he actually met Lukas. She knew if she was intimidated by the man, her husband would be tenfold.

“Yeah.” She answered, and she was quiet the rest of the afternoon, until it was time for her appointment. She wasn’t sure what to wear to this kind of thing. Did she put on lingerie? Did she put on tight clothing? Was she supposed to intentionally entice him? She knew she was an attractive woman but the idea of having to turn on a man she knew nothing about made her even more nervous. What if she took off her clothes and he didn’t like the way her nipples puffed up, or the pudge on her belly, or… oh, god, those stretch marks on her hips. For much too long she stood in their shared closet and debated about what to wear, just so she could take it off. She decided to go braless, and put on a thong and then a flattering winter dress. Those were all easy to remove. Practical, even.
For the first time in a long time, she stared at her body in the mirror before she left the house. She was only 23 compared to his 42. She wondered if he might like her body regardless. Maybe if she was even perkier than his wife was. Tighter than his wife. More flexible. Those thoughts steadied the ballerina as she got into her car, and started it up.

She didn’t know what to expect, and the entire drive back to the clinic she was trying to keep calm. In the parking lot, she spotted Lukas getting out of his own car. His dark-tinted Audi hardly seemed like it would fit him. Compared to her SUV she imagined he might even fit in her own better.
As soon as the thought crossed her mind, she shook her head quickly, trying to remind herself to stop trying to fantasize about long term anything. Even about short term anything. This was a one time thing. She couldn’t have images of him driving her car, using his freehand to grip onto her thigh as he drove. She loved her husband. That wasn’t ever going to happen. She didn’t want it to happen… right?
She was so distracted with trying to understand her emotions that she hardly realized she was next in line.

“Can I help you?”

“I’m here for an insemination appointment.” She answered, now more matter-of-factly. She was just doing this because she had to. At least that’s what she kept telling herself. A few minutes later, a nurse opened the door to the lobby.

“Right this way, Mrs. Hayes.”

—————–

The medication they’d given her was already starting to work by the time they were taking the elevator down to the ground floor in the following building. Nadia could already feel her cheeks flushing with the arousal that was flooding through her now. If she could have ever imagined what being in heat would be like, this was it. Whatever that pill was, combined with her ovulating body, it made her ache for sex in a way that was so frustrating she could cry. By the time she was led to the suite she’d be bred in, her pussy had swollen up so much it was straining against the thong between her lips, pushing down on her sensitive clit. There was a puddle of arousal drenching her legs and her eyes widened as she realized it was starting to stream down her inner thighs. Was that some side effect? Was she supposed to be so horny her pussy was pulsating for penetration… doing absolutely nothing?
Even as a teenager, Nadia had never experienced such a vicious need for a man to dominate her. Instinctual, dirty thoughts that she might worry would send her to hell for having, started flooding her mind. Without any prompting. No need to read erotica this time. Her nipples were now completely puckered up against her dress, and she had the indecent urge to rub and pinch them herself, desperate for any stimulation. So desperate she considered reaching down and pumping her finger into her hole right there in front of the nurse.

It took everything in her to hold back moans as every step forward caused the thong to shift between her legs. She must have been a sight to see then, when the nurse opened the door to the suite, and she was already breathing heavy, her voluminous hair already wild from how many times she’d nervously run her fingers through it. She’s never been so horny in her life. At the sight of Lukas she wanted to damn near attack him. The door closed behind them, and she heard a small click. Some look of desperation came to her features, as the need to be presentable was now over, and her lips hung slightly ajar, in a pant, as she tried to speak. “I—” but her body cut her off with an involuntary distressed moan, like it was forcing her to moan because there was no other way to placate this intense desire.

Lukas, still dressed, gave her a worried look, and then quickly strode forward, to take hold of her upper arms. Just as Nadia had expected, his grip was so harsh without even trying. He held onto her until he realized she wasn’t in pain… or at least, not the kind of pain that she didn’t want to give into. She was painfully horny and he realized that as the heavy scent of her pheromones began flooding the room. Then he chuckled, though he still tried to find her eyes, as if he were a bit worried about her.
“You’re in bad shape,” he commented lightheartedly, his dark loose curls fallen aesthetically into his face, and Nadia almost felt it cruel of him to not throw her on the bed right now and fuck the lust out of her. He clearly could see how badly she wanted it. Were formalities really necessary? And the joke… Nadia was typically so proper and reserved, now she wanted to tell him to shut up and choke her already. It took everything in her not to blurt that out and instead, she tried to catch her breath as Lukas continued.

“I didn’t mean it like an insult,” he promised. One large hand reached up to push some of her hair out of her face, and that touch alone sent heat through Nadia down to her very core. “Is that okay?” he asked, quieter now, voice deep-toned as his eyes found hers, and didn’t look away. She bit down on her lip harshly, nodded, and some instinctive need to arch her back, ass out, nipples upward, overtook her. She nodded, and let it consume her, arched her back for this man twenty years older than her, right there for him to come fuck her pussy.

There wasn’t much distance between them now, and with him towering over her by almost a foot and a half, his cock was at belly level with her. She could feel it’s heat, bulged out of his sweatpants as it strained against them. She was almost frightened at what she felt pressing up against her belly. It was larger than anything she’d ever tried to fit inside of her before, she could already tell without even looking at it. It was heavy, and she could feel it throbbing powerfully against her skin. A part of all that nervousness panged back into her again, as she realized this moment, even though her body wanted it so badly she felt stupid with lust, she was certain something that girthy wouldn’t be able to stretch her. The fear must have shown in her features because he chuckled softly, hand cupping her face now, as his thumb brushed over her cheekbone soothingly. “You don’t have to be scared. I’ll go slow.” Somehow he was so cool and collected, while she felt like a horny mess. “How much of that stuff did they give you?” he asked, sounding a bit amused, as he noticed how hard her nipples were, how she was arching for him already. In contrast to his words, his touches on her were so gentle, though she now had a very strong feeling that was intentional.

“I—I don’t know, um… 200mg, I think they said.” Nadia answered, flustered. With his hands on her now, every second he was still clothed and outside of her was torture. Her palms unashamedly found his chest, well… really, just below his chest. He was so tall her hands comfortably fell on his own abdomen, where she could feel the thickness of being well-fed and well-trained beneath her fingers. She half expected him to have visible abs—no wonder he was so huge. Somehow it was even hotter to her that he wasn’t some chiseled Greek god; it made him more human, though not less intimidating. If anything it was more intimidating. His body felt powerful.

“Really?” he asked, an eyebrow lifting. Was this some game to him? Why was he being so casual while she was damn near ready to beg him to touch her? It took every ounce of self control she had to not start rubbing her nipples up on his belly, and reach her hand down to take a real measure of just how big that monstrous thing between his legs was. “That’s how much they gave me,” he continued, his hands now smoothing down from her shoulders to her arms, and finally to her hands. Her breath hitched when he lifted them by the wrist, and guided them onto his cock. The density of his dick was lethal combined with that much girth, that much length. His cock was hard. Not hard like she was used to, hard like she’d never felt before. It was completely solid, with only enough give for the thick veins that lined it to pulse powerfully and stretch its head through her grip. “You’re so tiny. That must have went right through you…” he commented, still so calm for what was happening here.

******

Then without much warning, he reached down to wrap his hand around hers—it was so much larger that she couldn’t even pull away if she wanted to. But she didn’t want to, as he began guiding her fingers into a pump on it, and Nadia felt herself become overwhelmed. Her mouth salivated for it, to taste it. She’d never felt such an urge in her life. But with both of her hands being guided up and down his heavy cock, she realized how badly she wanted to suck it. Another needy, involuntary moan left her, and his expression became more stern, as his own breathing began picking up, but he was still so in control. His free hand found her chin, and his thumb brushed over her lower lip, which was still ajar with panting. “Shhh. I’ll give it to you. That stuff really works, huh? Back in that office, I thought you were gonna call and cancel as soon as you got home.”

Oh, if only he knew how wrong he was. Nadia felt herself melting into the need for him, giving herself up to his dominance in a way she could never imagine doing with her husband. “No,” she moaned, trying to catch her breath as her lusty gaze reached his eyes with batted lashes. “I wanted you so badly, even in that office,” she confessed, as if it didn’t hold the betrayal that it did. It came out so easily, just as all her own juices had at the mere sight of him. She realized Lukas must have found that knowledge to be arousing of his own, as he suddenly became very serious and quiet, though he held her gaze. For a few moments he just stared down at her, his hard cock throbbing for engulfment, now laying in her hands. It was so long it reached halfway up her forearms.

“Get on the bed.” He suddenly demanded, all traces of the gentleness and amusement he’d had moments ago gone. “Now.” His jaw flexed as he said it, and with him towering over her, she felt something akin to fear in her belly, but it was quickly drowned out with how hard her pussy began tugging into itself. The aggression she’d known he was capable of was now here, and it made her hole ache to be abused the way she knew he was capable of.

Nadia got up on all fours, and like some other force was controlling her body, all willpower left her, and she completely submitted to him. Behind her, he was taking off his shirt, and then she saw as the clothes hit the baseboard when he kicked them aside. That display of the power he held behind his strength made her ache for him even more. There wasn’t a thought about her husband now, or how much she loved him. Her mind was dazed with the type of lust that caused her to fantasize about things she never did before. As Lukas stepped between her legs, she imagined him forcing her head down into the pillows as she screamed. Between her legs she was dripping a long chord of arousal from her pussy down into the plush white comforter. Her pussy was so swollen and giving off heat now that her hole was squeezed almost entirely shut with every pulse that went through it. It tugged on her asshole for penetration, and she moaned out a desperate and pleading noise, innocent but distressed. She just wanted him to fuck her already. Not for the cum, not for the pregnancy, but because she desperately, desperately needed to have his cock stretch her open.

“Mmm,” he groaned, deep and gruff, from behind her, as she felt his fingers reach her glistening, puffy pussy lips, and slowly part them. “Christ,” he grunted, and Nadia began moaning without shame. She couldn’t help it as his thumbs pushed apart her swollen mount to get a better look at the hole he’d be trying to force himself into. For a woman that he could fuck standing up while she was lying down on the bed, Lukas had known she’d be tight, but he never would have thought she’d be so tight that he wouldn’t be able to fit more than one finger inside. As he finally gave her what she’d been pleading for, his large middle finger tried to squeeze into that tight, tiny hole. When it barely gave, even with how soaked she was, he let out a quiet breath of air. “Whew. We… are gonna need that lube.”

Somehow even with Nadia practically writhing with pleasure beneath his finger, Lukas was still relaxed, though his cock was now getting redder and thicker with every thrust of his finger. How her walls squeezed warmly down on it, so tightly to prevent him from leaving. How her hole clung to his finger when he pulled it back. He could feel her pussy convulsing around his finger already, and he harshly pulled away, quickly, as if it were punishment. “Aht aht. Don’t you come yet.” It left him authoritatively, aggressively, almost in a growl. “You want to get pregnant, you cum after I fill you up.”

He took a look down at his cock, then picked it up purposefully, and slapped it against his other hand with heavy preparatory thuds. A soft grunt left him at the feeling. Then he suddenly slapped it against her pussy, heavy and dense with every slam it made. It caused some of her arousal to splash off of her and onto his cock, and he chuckled behind her, though now he didn’t sound amused, but more menacing. Nadia panted between her moans, as she watched him walk over to the bedside table, pick up the large bottle of lube and bring it back over to her pussy. His cock had swayed heavily in the air as he walked, and she felt that pull of tension in her belly again. Suddenly, now that he was ready to put his cock in, she felt more nervous than horny, and her breaths picked up. Her cheeks felt hot and her belly erupted with a mass of butterflies as she felt the cool lube pile up on her hole from a stream above it. Her hole throbbed it down inside before he could even start pumping it into her himself. As he did the pangs of pleasure exploded rhythmically through her body, and she began to shake. Lukas now seemed frustrated as he withdrew his finger again with a sigh after just a few seconds of finger fucking her. “What the fuck did I tell you?” He now came down on her, so he could speak into her ear, his breath on on her neck as he whispered threateningly to her. “Stop trying to come before I let you.”

“I can’t help it,” she pleaded out, and it was the truth. With his full weight on top of her now, he was able to wind his arm around, and choke her from behind, to force her to look back at him. Another needy moan tried to escape her at the shock, and her pussy arched up into his abdomen primitively, where she tried to rub it against his skin.

This only made him angrier, and he used his other hand to slap her face, like discipline. “Yes, you can. Breathe through it.” He paused, as he finally let up and released his hold around her neck, and pulled back. As he rubbed his cock head on her clit from below, he reminded her of something that he thought maybe she was forgetting. “No amount of lube is gonna stop this from hurting. I’ll go slow. Breathe through it.” Some low grunt in his throat rumbled out as he lifted one leg to anchor himself on the bed, and lined his head up with that tiny hole. This type of pussy was so tight, trying to take his amount of girth would take patience. He gripped onto his cock purposefully, and held his head directly in line with her hole, before he started trying to push it in.

Nadia’s body responded almost immediately, as the girth of the very tip of his cock stretched her beyond belief. Beyond anything she’d ever had try to open her. Though Lukas was going slowly, her hole was so tight it wouldn’t easily accommodate his cock. As he pushed in he met resistance, and then the insertion failed, and his cock slid past her pussy hole, slick and carrying a coating of lube and her own arousal up her asshole. He grunted quietly in frustration. As he realigned his cock, now dripping with it all, he wondered if maybe she had been right in the conference room after all. Maybe anatomically this wasn’t going to work.

But he had a grand on the line. She had a pregnancy. He pushed the very tip of his cock back into her forcefully, and she cried out in a lusty moan that died down into a soft hum of ecstasy as he began working her tight pussy hole open.

He released a drawn out groan under his breath as her pussy finally began to give a little, and stretched just a tiny bit more to accommodate half his tip. “Mm. Fuck. That’s tight.” His own arousal began to climb inside of him, and his entire body felt alive in the bliss of fucking such a tight pussy. He hummed out a low groan of his own as her hole finally gave again, and his entire cock head popped inside. “Fuck,” he grunted, as Nadia gasped, her eyes rolling into the back of her head. She’d never had her hole stretched like this, ever. Much less by a man twice her size and age. His mature, powerful cock felt like some kind of drug as it forced its way through the tightness that held it back. They fell into a rhythm and Nadia had become so overwhelmed with how good it felt, her moans became longer, louder, with more depth and less willpower. They exited her involuntarily, moaning so passionately she could hardly hear it when Lukas told her to turn around. She didn’t notice he wanted her to until his cock had been dragged from her vice-like walls, and he practically had to pry it out of her hole as it clung to its veiny girth. It left her feeling empty, but dazed, as she fluidly turned around to lay on her back. Her eyelids were hooded now, and as Lukas came advancing down on top of her, her tongue fell from her mouth. She panted as he pushed her legs up and the very tips of her toes reached his shoulders. She was too short for her ankles to rest on them while he fucked her. Anatomically impossible.
