Butterflies didn't begin to describe the jittery feeling she had in her belly as she sat in the warm, sweet smelling waiting room. She'd saved diligently, planned meticulously, did all the research she could before offering her body to be a mother for monster kind. She'd picked this clinic because of the excellent reviews. The bulls were attractive, polite, big, and well trained to serve their women. Their breeding sessions were long, the studs promising tons of warm up and slow love making. Their belief that more female orgasms led to more successful pregnancies wasn't exactly scientifically proven, but no one has complained and many happy ladies leave thoroughly bred and often come back here for the second or third children, so they accept it as gospel. She was sure this would be worth all the months of saving.
Still, now that she was here after doing all the set up, paperwork and traveling, the reality of what she was going to do started settling. She was equal parts excited and nervous. She was no stranger to sex, but breeding? For a job? She'd also never been with a monster before, though she always wanted to be. She knew this was a service needed for their people and the idea that she was doing this for a specific purpose sent tingles through her lower belly. She'd never felt a lover raw before, and she was eager to try. She wondered how it must feel without the thin film of a condom between them. She wondered if she'd feel the heat of his semen, if his throbbing could be felt more clearly when they were unprotected. She wondered if-
"Miss (Y/N)!" Her name was called by a friendly human nurse, pushing through double doors. She was snapped out of her day dreaming and stood to attention a little too quickly.
"Y-Yes! I mean, uh...Yes, that's me," She mentally kicked herself;
way to look too eager
.
The heavily pregnant nurse giggled a little, "You can follow me this way!" She waved her hand, gesturing for (Y/N) to follow. She grabbed her belongings and quickly followed after her, trying hard not to stumble over her own feet in excitement.
"Is this your first time?" the nurse asked her, humor in her voice.
"O-Oh uh...Yes, it is," She looked down at her feet, feeling a heat spreading over her face. She wasn't sure why she felt embarrassed to admit it. Maybe it was the idea that they knew exactly what she'd be up to for the next couple hours.
"Oh dear, I don't mean to tease," She patted her shoulder as they walked, "I can just tell you're excited. With good reason too." She winked and nudged her side, "Trust me. You'll love this place, and you picked out a good stud too. He lives to serve!"
The nurse led her down the long corridor, leading her past other rooms where she could hear the faint sound of moaning women and bulls. The soundproof doors only doing so much to mask what was happening behind them. The sounds excited her, hopefully she'd be like them soon. 
"And here we are! This is your room. Let's get you inside and acquainted with your new friend." She smiled and led her into the room. It was a clean, simple room, clearly designed for one thing. In the center was a modified massage table. It was wider and adjustable, accessorized with straps and ties to keep the breeding female on her back, thighs spread wide and wrists tied above her head. Simple stands nearby had lubes, oils and toys available to use and a pleasant floral smell made the room feel welcoming.
"Welcome, Miss (Y/N)." She came face to face with her chosen stud as he stood from his comfy chair to greet her. He was a large man, bigger than she was expecting. Fluffy chest and legs, with large curved horns adorned his head of black hair. He was only clothed in tight, cow print briefs that left nothing to the imagination. She couldn't help but ogle him. He politely ignored her drooling and gave her a kind smile. "It's a pleasure to finally meet you." His sweet voice eased her racing mind.
"The pleasure is all mine!" She was worried she sounded too eager, but he didn't seem to notice and approached to grab her hands.
"I promise to make this experience as pleasurable for you as possible. Your wish is my command." He pulled her hand up to his lips and kissed it tenderly. Her stomach did flip flops.
"He will be the one to walk you through the rest. We are always available if either of you need any assistance. Otherwise, have fun you two!" The nurse took her leave and shut the heavy door behind her, leaving the two to their 'work'.
She stood there awkwardly for a few moments before speaking, "I'm sorry, this is my first time...uhm...breeding. I'm a little nervous."
"That's understandable." He approached her and tentatively put his hands on her shoulders, "Ultimately, I care more about your comfort than just doing my job. Please let me know how I can help you. Or, you're free to go, if need be. Not sure you'd get a refund at this point though," he chuckled nervously.
"Oh no! No, no, I don't want to go anywhere!" She quickly denied; no way in hell is she walking out of here now. "It's just been a while and...uh...well, I like kissing?"
He smiled and leaned down close to her face, stopping just before her lips, "May I?" 
She felt shivers running down her spine, his voice soft and sweet, seeking her consent so earnestly. She nodded and leaned forward, pressing her lips to his. His lips were soft and he smelled so nice. She stepped closer to him and allowed his prying tongue into her mouth. He moaned in response, tasting her as his large warm hands began running over her sides and hips.
"If it helps, we start with a full body massage. It will relax your muscles and mind," He muttered against her lips as he slid his hands slowly under the hem of her shirt. His skin against her bare belly felt hot, the proposition was enough to make her wet.
"That sounds wonderful!" She eagerly lifted her arms to help him take her top off. "I could really use one, honestly."
"Then I promise to be thorough. Get undressed and lay on the table please. I never understood why humans wear those silly things anyway." He chuckled as she tossed her bra to the side. She agreed.
She didn't need to be told twice, shedding the rest of her clothes before laying face down on the cushy massage table. Her excitement was starting to overtake the nervousness she felt. Maybe it was the way the room smelled, it was very soothing and it made her head feel fuzzy.
"Now just relax, I'll take good care of you," He ran his hand down her back and to her ass, savoring her curves and smooth skin. "Beautiful." His voice sent shivers down her spine. Goosebumps rose on her skin as he poured the warm oil over her shoulders and down her back. Gently, he began working it into her skin, massaging the tension out of her with expert hands.
She moaned as he rubbed little circles over her tense shoulders, "You're really good at this..."
"I'm glad to hear it! I hope you'll allow me to massage all of you. The more relaxed you are, the better. Your body is also very..." His hands slid down her back to her ass and grabbed it firmly, "very beautiful." She bit her lip and moaned, the praise sending thrills from her head to her toes.
"Please...your hands feel so good..." She lifted her hips a little to entice him to move his hands lower. He understood and moved down to slowly rub and knead her ass. She spread her legs and he responded by running his warm slick hands between her thighs. He would barely touch her pussy before moving his hands back to her inner thighs and ass. She bit her lip, frustrated. The bastard was teasing her!
Sticking to his promise of being thorough, he moved down to rub her legs and feet as well. As impatient as she was, she had to admit she was pleased that he meant what he said. "You're really really good at this." She praised, hoping that would spur him to go faster. She let out a giggle as he rubbed hands over her foot, tickling her.
"You make it very easy." He smiled at her, "Now, would you mind rolling over for me?"
She complied, rolling onto her back eagerly. He stood next to the table, leaning over her to run his slick hands over her breasts. She moaned and arched her back, pressing into his hands. He wasn't touching her nearly as much as she wanted. Her whole body felt so warm already and he was taking his sweet time. Impatient, she reached over and ran her fingers over his hard cock through his briefs. To her delight it pulled a moan from him, but he stopped her hand. "You first. I need you to be ready to take me."
She wasn't worried. The thick member was already rock hard and throbbing, bigger than she thought he'd be, but she could absolutely take him now...probably. 
She whined as she laid back and let him run his hands over her waist and belly. "You're being so slow...I could take you now, honest!"
"I just got started," he chuckled, sliding his hands down to her hips. She opened her legs for him, praying he'd massage her between her thighs and ease the ache building in her belly. As if he could read her mind rubbed her inner thighs and hips, only grazing her pussy. She couldn't help but move towards his touches, getting desperate. He would avoid her movements, building more tension in her body.
"Please!" She cried out when he lightly ran his fingers over pussy and moved away again. This game was getting too much for her, and she snapped her knees together, trapping his hand between her legs.
He chuckled, "I'm sorry. You're just so cute when I'm teasing you." He leaned down and gave her a gentle kiss as an apology. He eased her thighs apart again and his hand slid between them. She moaned against his mouth, spreading her legs further. "Let me give you some relief." He muttered against her lips, dragging his fingers over her slick folds. 
Finally!
Sighing in relief, she reveled in his gentle, coaxing movements. His hand started rubbing in slow, steady circles, his other hand groping her breast. Her head felt fuzzy, all she could think about was being deeply fucked. She parted her lips to kiss him more deeply and began rocking her hips against his hand. She was so ready, she had no idea how he was controlling himself, she was so horny she could barely think. "Please please please...." She muttered into their kissing. 
He decided to give her a taste of what she wanted and slid two of his fingers inside of her, moaning as he felt her heat. Her knees fell open and her hips rocked in time with his hands. She'd been teased so much, she could already feel herself getting close. Just a little more...she reached up to grab a handful of his hair and pulled him into a deeper kiss. Almost there....
She cried in despair as he pulled his hand away, "W-Wait! Please don't stop!" She gave desperate little hip thrusts, aching for anything to touch her.
"I'll let you come soon," He promised, kissing her forehead reassuringly before moving between her legs. He rained little kisses over her hips and thighs, "I want the first time you come to be on my tongue."
The dirty words hit her core like lightning. She whimpered as she felt his warm breath over her sensitive pussy, "Please...!"
A slow, dragging lick through her folds was her reward for begging. It pulled a moan from deep in her throat, and her back arched. "Delicious." He muttered against her pussy before burying his face in her. He sucked and licked and kissed, every movement tender and slow, savoring her against his tongue. She felt like she was melting, she was so wet, her body so hot. Her mind was numb, she could only focus on the slick warm heat of his tongue, and the coil of pleasure being wound tight in her belly. He was just...so...slow...deliberately keeping her right on that edge of ecstasy. His large hands held her around her waist, limiting her movement. She caught him looking up at her, a mischievous look in his eye. He did promise to make her come, but it was only going to happen when he wanted it.
"Oh god! Oh please don't stop, I'm so close...!" She panted, her body was tense, she was right there, she wanted him to finish her so badly!
He stopped licking, only pressing his wet, soft lips to her clit. He spoke between kisses, "See?"
