#3 of YiffCo: Hornier than you

A pick-up truck tooled down the high-way, its tires humming on the asphalt. The driver, a blue Arabian stallion named Roy, had one propped against the door as he used his fingers to steer. His other rested across the back of the seats, just relaxing as he let cruise control handle the speed. He had bought the truck a while back, but never used it unless he had to go into town for personal business. Normally, he would just borrow the truck from the farm he worked at, but since he often had another farm-hand come along with him into town, he had bought one with an extended cab.

Sure, it was a bit of money to spend just to have something a bit bigger than that old, beat-up work truck. But there was definitely some other advantages, like the radio that worked, the CD changer stashed behind his seat, AC, power everything, and cruise. Besides, he wasn't spending his pay on much of anything else. Life at the farm gave him daily exercise, he got three square meals a day, and plenty of fresh air. Plus, there were other benefits since the farm he worked at was more of a resort type thing where people came to get away from it all and spend a few days or weeks out in the country. Plenty of fun to be had with hiking, swimming, camping, or just having sex with the other guests or employees.

Usually, he'd be more than happy to spend not only his days at the farm, but every moment he was awake. However, he had heard about a company that was paying people crazy amounts of money to test out their products. So after some talking with Steve, the owner of the farm, he and Dakota, his gal, had decided to take a little vacation. Their destination was about a day's drive each way, and the had several weeks of vacation stored up. So they packed up some camping gear and hit the road. "Dakota, we should be getting to the city soon." He looked down at the female with a smile. The Clydesdale female had her head in his lap, her muzzle wrapped around his cock. Reaching his free hand down, he ran his hand through her creamy blond fur. One of her deep brown eyes looked up at him, the other hidden behind a wing of hair that always covered it up. He could read the question in that lovely orb, letting his hand move down to tug her shirt up and bra up to free her chest. "I'd say 'bout another half-hour or so before we get into town."

She nodded, sliding her lips over his length before pushing back down to take his spire all the way to the root. He groaned and gripped the steering wheel, feeling how the mare worked over his cock. They had stayed in the tent a little that morning, having their morning romp. After that, getting everything packed up, another bit of fun that had Dakota bent over the picnic table, and then breakfast; they had just missed the morning rush hour. Which was definitely a good thing since this was her favorite road trip game. The mare could probably be called a nymphomaniac and Roy... well hell he was just a stallion and when his mare was in need of a good stuffing, he was ready.

He shifted in his seat, grunting a bit as Dakota started to really work him over. The mare's cheeks caved in a little, her broad tongue pressing him against the roof of her maw. Bobbing her head up and down, she fluttered her lips against his shaft, giving a different feeling as the suction was removed and applied quickly. Her hand shifted to cup his heavy sac, rolling the hefty orbs in her paw as his head fell back against the seat rest. They had done this often enough that the Arabian stallion had gotten to where he could drive easily while she did this. Grabbing one of her breasts he kneaded the soft, plump mound, as she kept giving such a great blow job. Panting, he felt his loins tightening and let out a loud neighing noise as he blew his load. Dakota knew what was coming and pushed her head down, swallowing his cream as the stallion erupted inside her mouth. Her eyes closed dreamily, feeling that salty essence splash over her tongue then roll down her throat.

Once he was done, she pulled her mouth up and tucked his cock away, zipping the stallion's pants back up. Pulling her shirt back down, she moved her seatbelt back over her arm and drawled, "Well?"

Roy hit a button on the dash and frowned, "Fifteen miles, you win again." Dakota sat back, a smug expression on her face. That was her favorite game, they'd make a bet on how far he could drive (doing the speed limit) before she could make him cum. This time they had wagered the first choice of positions during their next rutting session. Despite the fact that he got a great blowjob from his mare, Roy just didn't like the idea of losing. "Your turn, and how about we wager..." he reached up and scratched his chin, the bristly hairs on his muzzle making a dull scratching noises, "I get to pick the next sex toy we use."

Instead of saying she accepted Dakota, who was a mare of few words, began to unbutton her pants. Lifting her rump up some, she pulled her jeans and the thong she was wearing down to her knees. Grabbing a towel from behind the seat, she slipped it under her rump and scootched forward a little. Roy let out a soft murr and licked his lips as he looked over. Her fur was a reddish brown color, with a frosting of blond along her belly and inner thighs. Nestled between her legs was her treasure. Reaching over, he put his paw between her thighs and gave a little test rub over her soft labia. "I think I can make you cum in fifteen miles."

She snorted, "If you don't wanna play right, Roy..."

He chuckled at her and reset the trip meter, "Okay, ten."

The mare shook her head, "Five."

Roy thought about it, "Five and I get to pick when we use the toy too."

Dakota reached up and brushed her hair back before that one lock fell back over her eyes, "Deal."

With only five miles to try and make her cum, Roy didn't have a whole lot of time for niceties. Resting his pointer and pinkie fingers on her crotch, he let his two middle fingers dive into her snatch. The mare let out a gasp and pushed her hips into his hand, loving it when he did things like that. Wiggling his fingers into his mare, the stallion smiled. He got those fingers in at just the right depth and began to jiggle his entire hand up and down, letting those two fingers tap against her G-spot as his palm rubbed her large clit. His lips curled up at the corners as the mare grabbed onto the seat and armrest, gasping as her head fell back against the headrest.

She was already moist when he pushed his fingers into her pussy, which wasn't too surprising. She loved giving him some head and he'd joked before that she could cum from that alone. Thinking about that made him remember the time they had tried to do just that. All the guys are the farm lined up in front of the bound Dakota and let her give them head. She hadn't been able to actually orgasm from that, but she was as wet as a cat in a rainstorm when they got done. Smiling at the memory, Roy wiggled his fingers as his hand pumped up and down against her insides. His ears twitched as he heard the wet squishing noise of his fingers pumping inside her. A quick sidelong glance painted a glorious picture. Dakota's hands were holding onto the armrest and the seat for dear life. Her head was tilted back as she gasped for breath, those breasts of hers heaving under the cover of her shirt. He could feel how her hips jerked, her breathing pattern changed, her scent shifted a little, and knew what was coming.

Pulling his fingers out of her suddenly, he let his palm rest against against her pubic bone. The mare screamed out in climax as her body jerked like a fish out of water. While she spasmed, her pussy clenched and gave a couple squirts of her juices onto the towel she had under her body. He smiled and let her calm down before moving his hand. Lifting his fingers to his lips, he licked them clean slowly and smiled over at her. "Mmm, the sweet taste of victory, and mare juice." He nodded at the gauge, "One and a half miles, I think that might be a new record." The mare murred and undid her seatbelt before scooting over on the bench seat. Fastening up the middle one, the larger female leaned over to rest her head on his shoulder. Shifting his hand around, he wrapped it around her side and held her as they drove.

The rest of the drive was uneventful, other than the occasional grope here or rub there. Roy pulled around the big building and whistled softly as he looked at the towering sky-scraper over them. "Would you look at that?" He shook his head and turned towards the parking deck. Dakota lifted herself up to pull up her jeans and panties. "Hold up a second there, Filly, remember our deal." The mare looked at him, her one visible eye blinking slowly as he reached down next to the seat and pulled out a little bundle. "Got ya a present." Curious, she opened up the bundle and found a pair of panties. The Clydesdale looked at Roy to see if he was serious, "Go on, put them on, Sugar." With a shrug, she reached down to tug off her pants. The thong she was already wearing came off as well before she pulled on the new pair. They were red and soft, but were cut about the same as her other, black ones. She thought to herself that it must be a color thing, something about the red panties were sexier; but damn if the didn't feel a little strange around front. Pulling her pants back up, her ear twitched when she heard her stallion rustling something. Looking up, she felt her eyebrows lift curiously at the sight of a remote in his hand. It looked like his truck's keyless remote, why would he have that out while he was driving?

Her unspoken question was answered when he tapped one of the buttons. The little vibrator carefully hidden inside of her underwear began to hum silently, buzzing against her clit. Dakota's head fell back as she gasped at the sudden feeling. He chuckled and tapped a button to tone it back some, "You like your little gift?"

She nodded, "Yeah, but I'd have liked some warning, Hun." Pulling her jeans up, she buttoned them and zipped them up, shivering at the little vibe as it hummed against her swollen clit.

Roy pulled up to the parking deck and waited for the guard to let him in. Driving for a moment, he pulled the truck into a spot and cut the engine before letting his door swing open and hopping out. Dakota swung out on her side and stood up. The mare stood taller than the roof of his truck. She was large enough to look over the roof without having to get up onto her tippy-hooves. He smiled at the larger mare as he reached into the bed of the truck and picked up a duffel with a change of clothes and things in it. Dakota looked at their camping gear with a questioning gaze. The Arabian shook his head and nodded at a camera that was aimed right at the truck, "Naw, it'll be safe enough in the back with all this security." He tapped the keyless system for his truck, making it beep its horn and flash its lights as it locked up and armed the alarm. He dropped the keys into the duffel before walking around to the rear of the truck. He waited as the mare side-stepped between the pickup and the van next to it. Putting an arm around her, the shorter stallion walked towards the elevator.

Tapping the call button, he waited for the lift with his mare. She wasn't a whole hell of a lot taler tan him, maybe four or five inches, he never really remembered. Not that it really mattered, there was just something so sexy about watching the bigger female writhe under him and beg for more. The elevator dinged and slid open, the two equines walking into it and tapping the button for the lobby. He whistled softly as the machine carried them up several floors. Reaching into his pocket, he fiddled with the wireless remote for the toy. The mare let out a little gasp and gripped his side as it buzzed away silently inside her jeans.

A moment later the door opened up, letting them walk right into a very fancy lobby. Roy let out a low whistle and walked over toward the Skunk receptionist. "Yes, how may I help you?" After she asked, the female looked up at the pair, her eyes widening a little at the pair of large equines. Roy stood at about two inches over six foot, and was by no means a small boy. The constant physical challenge of working at the farm with horses and things had given him good muscle tone. It was hard to tell the build of his upper body thanks to his button-down flannel shirt. The sleeves had been rolled up, giving a hint at the muscles in his arms. But her eyes had stopped lower down. His jeans were loose fit, but didn't do much to hide the build of his thighs. Or the hint of a bulge creeping down one of his pants legs. Dakota was used to getting the looks anyway, since she was a tall girl with a body built to match.

Roy smiled and leaned against the desk, looking down at her as he drawled; "Yeah, we heard about this place from a couple customers at the resort farm we work at. So we decided to take a few days off work and make a road trip."

She cleared her throat and looked at the computer, "Of course, give me just a moment to see if anyone needs you two." The stallion stood back up and let his hand roam down to grab Dakota's ass, rubbing it. The mare let out a little grunt and lifted her tail up, pushing her rear back into his rubbing paw. After some typing and a couple phone calls, the skunk looked up at them and nodded. "Looks like we have something that they need a pair of equines for. Just take the elevator behind me up to the twelfth floor and go to the right."

Thanking her, Roy grabbed onto Dakota's rear with his paw and steered her towards the elevators. Not that she would need much encouragement as it was, but he liked getting a handful of that sexy ass of hers. There was already an elevator car waiting for them on the ground floor, so they just stepped inside and rode it all the way up. The blue-gray male looked at the glass rear wall and gave a low whistle as he watched the street below grow further away. "Would you look at that."

Dakota shook her head, "Nah uh, Roy, I'm fine right here." He chuckled softly at the mare and triggered the vibe up higher, watching as her knees almost buckled. The female let out a low, shuddering moan as he moved it up towards its highest setting.

Walking over, he turned her around and shoved her front against the wall as he ground his body against her rump. "Mm, when was the last time we did it in an elevator?" He gave her shoulder a firm bite with his teeth, the bite of a stallion to its mare to remind her who was in charge. "Oh yes, it was at the mall last year, during our holiday shoppin' trip." She nodded, huffing and panting as her body pushed back against his. Her body shuddered as she issued a gasp followed by a low scream as she came right there in the car. The mare pushed back and huffed as Roy humped his body against hers hard and grabbed her thighs with his hands.

The sound of a throat clearing made the pair look over at the doors, which had opened just in time to let Dakota's orgasmic scream be heard down the hall. A weasel in a lab coat was standing there and reached up to adjust his glasses, "You two must be the horses we were told about. If you would follow me, we have a room where you can...finish up. Other people might need this elevator." Turning, he began to walk down the hall as Roy followed, Dakota right behind him. The hall was sterile and gleaming white, as if a speck of dirt had never dared to touch down anywhere. The pair followed the weasel down the hall, the sound of their hooves echoing down the empty hall.

Stopping in front of a door, their escort opened up a door and let them move in first before following them. Spread out in front of them was what looked like a five-star hotel suite. They were standing in an area that was like a living room, with a couch, chairs, and a TV hanging on the wall. Beyond that was a pair of French doors that swung open as they approached. To their right was a door that led into a bathroom with a large shower/tub/jacuzzi thing and a toilet hidden in a little niche. A peek into there let him see that the shower had several nozzles. Past that was the bedroom, dominated by the largest bed the horses had ever seen. It looked to be about the size of two King-sized beds and it was actually set down into the floor. Their guide waved a hand at the room, "This is where you will be staying. We will need you to be here for a day, maybe two at most. Is that alright?" Roy didn't even have to look at Dakota before nodding. The weasel continued, "Good, I will need you two to strip down and answer some questions while we check your physicals."

The horses shrugged at each other before starting to disrobe quickly. Roy was faster at this part, used to being the one that got completely nude before helping Dakota or any of the clients at the farm. Undoing the first couple buttons on his tip, he tugged the shirt up over his hand and dropped it onto the bed. Next came his belt, which he coiled up neatly and set on a desk. Last of all was his pants, revealing the fact that the stallion was going commando. His dark skinned cock was already halfway 'dropped' from his sheath and dangling between his legs. Despite the loads he had pumped into the Clydesdale over the last couple days on the road, his sac was still plump with seed. His muscled rippled under his short, blue-gray colored coat. Shaking his head, he ran his fingers through his short, black mane. Looking at the piles of clothes, he shrugged then picked them up and folded them some before putting them into a drawer.

Dakota watched her stallion lover strip down, rubbing her thighs together a little as she undid the buttons on her shirt. She was much slower, taking her time for now to strip down. Once the shirt came off and revealed her bra, the mare folded up the blouse and put it away before reaching back. With a flick of her fingers, the snap came undone on her bra and it came off. Sliding it down her arms, she put it with her shirt before working her pants and soaked vibrator-panties off. Her muscle tone was defined, but not quiet to the extent of the stallion's. Her russet fur was a bit shaggier than his with the long, blond hair of her mane, and the long pieces on her wrists and ankles that hung down. Her dark skinned sex lips were puffy and the petals had parted to reveal her ruby inner lips. Her thighs and the short, softer hair around her crotch was matted a little with her juices. Her dark colored nipples stood up, semi-hard.

The weasel's eyebrows bounced a little at the sight of the two, healthy, and sexy horses that were standing there with nothing on beyond a smirk for Roy and a doeful expression for Dakota. "Please have a seat and just answer some questions while I check you out." He waved a hand towards the living room, leading the two horses in Roy and Dakota had a seat on the couch, Roy putting an arm around the female and letting his hand slide up under her to rub one of her breasts. "I am Doctor Rashin and I will be checking in on you two while you are here." He handed them a tablet PC, "Please just answer everything truthfully." Roy took it first with a nod and freed his arm before starting to fill out the digital form.

While he was doing that, the good doctor was listening to his heart, checking his blood pressure, and even took a blood sample. The last thing made the Arabian make a face and look away, he hated needles. The questions were pretty generic, asking about his medical history, any medications, weight, age, the hole shebang. He looked at it and tilted his head to the side as he read off the question, "Have you had sex with multiple partners in the last month? Who doesn't?" Answering some, he worked down the list a little more, "Have you had sex with someone outside your species?" He let his ears twitch against his skull, "Feral or anthro?" He looked at the weasel with a smile as the doctor looked at him with an arched eyebrow. "Have you ever eaten any exotic foods or juices in the last six months?" The stallion whickered and looked at Dakota, "Do you think that little piece of Persian tail counts? Oh, what about that zebra last month?" He chuckled and finished answering the questions as his tail moved against the couch.

Handing the PC over to Dakota, he let her fill out the answers while the doc checked her over as well. "Well, both of you seem to be in your prime. You're as healthy as...well... horses." Shrugging off the expression, he took the tablet and looked over their answers, "Okay, I will be back in a few moments with the product we are going to test. You two are okay with taking a simple injection, correct?"

Roy grunted, "What type of injection?"

The weasel just waved his hand, "A little hormonal cocktail we are testing out. Nothing to be worried about. Just wait here and I'll be back in a few minutes. The only thing we ask is that you refrain from any sexual activities." Without another word, he left the room.

Roy let his ears twitch against his head, "Nothing to worry about he says." Rolling his shoulders in a shrug, he put an arm behind Dakota. The larger mare leaned over and let her head rest on his shoulder, nuzzling into his fur with a soft sigh. People that knew them often joked and called this gentle touching and cuddling the calm before the storm. While it was true that the pair loved sex, there was something to be said about just sitting and rubbing each other as well. His hand ran over her spine slowly, each finger tapping against one of her vertebrae. Her hand was roaming over his stomach, tracing the vague definition of his abs under his coat. Turning his head, he nuzzled into the mare's mane as she nosed into his neck softly. They shared a soft sigh of contentment, smiling.

A little hiss was their only warning before the door slid open to admit Dr. Rashin and a couple other people dressed in scrubs with white lab coats on. They carried a little tray with a pair of needles on it, making Roy flinch a little at the sight of them. The weasel had Dakota lift her arm out and Roy watched as her arm was wrapped up and cleaned before they waited for a vein to appear before giving her an injection. The mare barely acknowledge the needle as it slipped into her skin and fired its payload. With a sigh, he held out his and waited. The doctor blinked, "Oh no, Mr. Trigger, we don't put your injection there."

The stallion adopted a worried expression as one of the nurses began to swab his inner thigh with some alcohol. "Hold up a sec, why did y'all inject her arm and not mine?"

The doctor droned on as the nurse quickly jabbed the needle into his flesh; "Simple, they are two different treatments we are going to test." Roy clenched his teeth as the plunger was pushed down as he felt the low burning sensation of the drugs being injected into his bloodstream. "Her injection is a simple mix of hormones that need to circulate through her system first. They are designed to increase her desire for sex and put her into a kind of false-heat. I wouldn't worry about impregnating her though, the chemicals aren't designed to trigger ovulation." Roy shifted as he felt the nurse dab at his thigh with a cotton ball, listening to the doctor. "Yours, on the other hand is designed to alter how fast your body recovers after an orgasm."

The Arabian scratched his chin as the nurses moved to dispose of the needles in a little receptacle; "So what you're sayin' is that her thing makes her horny as hell. An' mine makes me into that rabbit that sells batteries. I bust a nut and keep goin'?"

Rashin frowned at the stallion's drawl, "You could say that. I will be checking in on you two throughout the night. The drugs should take effect within a half-hour and wear off before morning. If you need anything, the computer in the bedroom is equipped to handle food orders and call for help." Then he left with his two minions and shut the door.

Now that they were alone in the room, Roy looked over at Dakota, "Chow time before we get too occupied?" She nodded and got up before he heaved himself off the couch. She led the way into the bedroom, her rear and tail swishing from side to side with each of her steps. Which was just an open invitation for what came next. She was almost to the computer screen when his hand smacked against her rear, making her jump and give a squeal of delight. Looking back at him, she gave one of her smiles that he loved so much and walked over to the screen before pulling up the menu. Roy sat on the bed, his cock already beginning to rise up and get hard. It was nearly impossible to tell if it was due to the injection or the fact that Dakota was damn sexy. Which reminded him, "Hold still for a moment." The mare looked back at him as he dug through their bag before pulling out a spandex sleeve. Turning her head back to the screen, she stood still while he carefully pulled her long tail hairs through the sleeve. It didn't take more than a moment since he was used to doing it for her and feral horses back at the farm.

Turning away from the screen, the mare uttered; "Well, should only be a few min..." A ding and the sound of polished metal sliding across polished stone made both of them look at the shelf under the computer screen. Twin trays, each with some food on them, were waiting for the pair. "Well, damn." He shared the sentiment, walking over and taking his seat in one of the chairs next to Dakota. By then his dark skinned tower of horseflesh was hard as a steel fencepost. Scooting over to sit next to the female, he smiled and began to eat, both of them occasionally reaching across to get a feel of the other's bare body.

When they were almost done with the meal, he noticed that Dakota was starting to breath heavier. Giving her a once over, he noticed other things as well. Her nipples were hard and peaked, her pussy was swollen and the lips had parted a little to reveal her inner lips. If he didn't know better, he'd have to say that the mare went into heat during dinner. Turning to look at him, the mare and stallion shared a look that said if all. She pushed the chair back and got down on the floor as he almost threw himself out of his seat on top of her. The equine pair skipped the any niceties for now, feeling a deep need to just screw.

Dakota threw her legs over Roy's thighs and arched her back as he tilted his hips back. His cock was actually so rigid it was a little hard to move it down at the right angle. After a second, he felt a wet warmth against his tip and shoved in. From that moment instinct and practice took over, guiding his shaft into her to the very hilt. She shoved her hips up and let out a scream of pleasure, clenching around his dick. Most males wouldn't find her to be the best fit thanks to her size, but to Roy it was like pushing into a glove, perfect fit.

Some lovers would take time after the initial penetration to hold each other close. Share some kisses, maybe whisper sweet little words to each other. Under the best of times neither Roy nor Dakota practiced such things. They seemed to live by the saying that 'Actions speak louder than words' and this was no different. Her hips pushed up against his as he hilted, their bodies meeting with the impact of flesh on flesh. pulling back, his ears twitched at the lovely sound of the mare's wet tunnel slurping around his stallion cock. Her head fell back as she uttered a low groan, feeling him already pounding into her body like a wild thing. She rocked on the ground as Roy held himself up a little, allowing her breasts to bounce freely with each motion.

His hands were planted on the ground at her sides, anchoring the stallion as he rutted his mare. His heavy sac, which he could swear was bigger after the injection, slapped against her rear with a solid slapping noise. Clenching his teeth, he snorted as he pumped his body against hers hard. The doc was right, it sure as hell felt like the Clydesdale was in heat. This sure as hell felt better than when she was in heat though, he hated the feel of those condoms. Like this, he could directly feel each squeeze and every trembled of her tunnel. And the opposite was true as well. She could feel his bare cock slipping and sliding in and out of her body, the mushroom tip grazing across her G-spot as he pulled back and slammed in again.

Dakota's hips jerked up against his as her hands moved down, her blunt nails grabbed at the carpet as she let out a scream of pleasure. Her body clenched around Roy as she came, some of her juices gushing out around his hammering length and down her thighs. Now, normally he would try to see if he could get her to cum a second time before he finished up; but it just felt too damn good right now. As she gushed around his member, he slammed in and let out a grunting noise as his sac tensed up. Inside her, the thick mammalian member twitched as it began to fire his spunk deep into her body. The head flared up and acted like a crude plug, keeping most of his seed inside her. His climax didn't last more than a second, but instead of immediately starting to soften he remained hard.

Dakota looked up at him, her chest heaving as he pulled out. Leaning down, he grabbed her head and kissed her firmly on the lips. She moaned into his mouth as her tongue moved to rub against his. They held the kiss for a moment before he pulled his head away and nodded at the bed. The mare nodded, her one visible eye sparkling as she rolled onto all fours and moved towards the bed. One looked at her as she moved over, her sex lips parted a little from the first fuck of the night, dribbling a mix of their love juices, Roy knew what he had to do.

Grabbing onto her hips with both paws, he slammed his still hard cock into her pussy. Dakota's head tossed back as she let out a heavy gasp, pushing backwards. Her knees were on the floor and her hands on the bed when he slammed in, perfect position to get plowed. With his cum and her honey coating her insides, the stallion was able to pound in and out of faster now. There must have been something in that little cocktail the nurses gave him that decreased his sensitivity after cumming, cause it felt like he hadn't had any tail in a couple days. His heavy sac slapped against Dakota's crotch with a wet noise as he grunted. His chest was heaving, sweat already starting to foam up on his hide as he pounded his body against hers.

Her chest fell down onto the bedding as she looked back at him with a lustful expression on her face. Roy knew what Dakota wanted and he was more than happy to give it to her. His hand swung and slapped against her ass hard, drawing a squeal from the mare and making her push her rear back against his hips. Leaning over the female, he used his blunt teeth to bite her shoulder like a wild stallion would his mare. Dakota let out a gasp and shuddered as small climax shuddered through her body. Out of all the females at the farm, she was probably the easiest one to get to climax. And Roy was the most experienced male at pleasuring her. He knew all the little tricks and techniques to make her weak between the knees and had almost made her pass out from a climax once.

Like any of that mattered right now. Their sweat-covered bodies rocked against each other as they huffed and panted, trying to draw more pleasure from the other one. Dakota rocked her hips back into Roy, wanting to get his cock inside her and feel another load of his cream splash into her body. Roy rammed hard against her, feeling how the female was clenching around his cock and loving the sounds of their rutting. Sliding a hand up, he wound his fingers into her mane and tugged on it. With a gasp as her hair was tugged, she arched her back and gasped out as she came around him again. Once again, instinct was guiding the stallion and he shoved in as her juices flowed down her thighs and dripped onto the floor. He let out a low grunt, shuddering as he pumped his load into her body.

Dakota let out a low moan as she felt his tip flared inside her, spurting his seed deep into her body. They weren't done yet, the drugs made sure of that much. Grabbing onto her sides, Roy heaved to the side to move the mare. Despite the fact that she was larger, he had plenty of practice moving the bigger female around. He sat on the edge of the bed with her in his lap, facing away from him. Without a single word between them, Dakota and Roy shifted so they could get their feet onto the bed.

Not even a minute after their shared orgasms, the pair was at it yet again. The mare bounced in his lap, rubbing her rump against his abs as he wrapped his arms around her. Laying down on the bed, he pulled her with him so they were both laying back. With her legs spread and feet planted, Dakota began to rock on his body as she huffed. Roy reached up and grabbed onto her breasts, squeezing the mounds in his paws as he shifted his legs a little. Putting his feet right next to each other, he began to pound up into her fast. His cock hardly moved more than an inch as it pistoned in and out of her soaked tunnel. A mix of their combined juices dripped out of her snatch, the thick concoction covering their crotches and sliding over his hairless sac.

Her body tried to match his pace, but it was too furious as he jackhammered her lower lips. His hands grabbed onto her breasts, tweaking and twisting the nipples. He let out a groan that built in volume as he took her like there was no tomorrow. Her body quivered like a tightly wound spring as she grabbed the sheets. Her mouth hung open as she tried to scream her pleasure, but nothing louder than a moan was coming out. The feeling of his perfect prick pumping into her plump pussy brought indescribable amounts of pleasure to the mare. Her eyes rolled back into her head as a silent orgasm wracked through her body, making her clamp down around his cock. She managed to huff out something as her body spasmed. This seemed to drive Roy to higher states. He began to yell with renewed vigor as his body pounded against her so hard there would surely be bruises in the morning.

Dakota gave a trembled before she managed to voice a yell of pure bliss, quaking around him again. That scream set off the stallion, making his body freeze were it was, his tip just barely resting inside her snatch. With a grunt, he began to cum again, his sac spurting its cream into her body. The mare shuddered and slumped down as she passed out from over-stimulation, his cock slipping free of her body with a wet noise. He huffed, a couple spurts of his seed splashing across her belly and thighs as a flood of their passions spilled across his crotch. Roy panted, his heart spinning inside his chest as it tried to keep pace with the wild and reckless fucking. Taking a deep breath, he coughed once then released the air in a huff. Slipping one arm around Dakota, he worked up higher on the bed and rolled her off him. The mare let out a soft snort before shifting to lay against his side. His head fell to the pillow and within just a few seconds, the pair was starting to breath deeply as they slept.

Roy wasn't sure how long they were asleep, but he got a very nice, familiar, wake-up call. He was roused from his sleep by the feeling of a warm tongue tracing his sheath and a hand fondling his sac. Opening his eyes, he looked down and smiled as he saw Dakota's head resting over his crotch. The opening of his sheath bulged a little before the tip of his cock came out. Within a few seconds, he had fully dropped from his sheath and his cock was resting on his belly as it pumped full of blood. He was thankful that he hadn't stayed hard while asleep, however long they did rest. The mare opened her mouth and closed her lips around his tip, suckling on it a little and rubbing his shaft. The stallion let out a low huff as her attentions quickly brought him to full hardness again. Damn, she was so good at that and he was pretty sure that she could suck the chrome of a trailer hitch.

Pressing a hand on her shoulder, he rolled his mare over onto her back. Moving over her, he noticed that his sac did seem a bit bigger, must be something to do with those meds. Shrugging it off, he put his cock between Dakota's breasts, whickering a bit as she pressed the mounds together. His hips began to rock as she leaned forward and licked at the tip of his cock each time it poked out from her cleavage. Reaching a hand down, he began to pinch and tweak her nipples as she moaned, her excitement growing again. Grabbing a pillow, he moved it over and stuffed it behind her head. Dakota lifted her head before he even moved, laying it back into the support.

The pair didn't have to talk much to let the other one know what they wanted to do or needed to have done. With the pillows behind her head, she was able to open her mouth up and let his tip slip right into her long muzzle. Her cheeks caved in slightly as she sucked around his tip before letting it pop free of her lips. Roy let out a grunt of pleasure and increased his thrusts, feeling how she was tending to him. He leaned back a little and smirked, his other hand slipping back to give him some support. By leaning back, he managed to stuff a little bit extra into her waiting muzzle; but it also let him get his hand down between her thighs and rub her messy cunt.

Her body shivered as she moaned, feeling two of his fingers dip into her soaked snatch. Her one visible eye drifted closed, the other hiding behind the veil of her hair still, as her hips wiggled some. Now it became a kind of race, who could make the other blow first. Could Roy win using his fingers despite the fact that he started later. Or would Dakota win since she had the head start and was putting her mouth and breasts to good use.

Pushing his fingers in, he used the dull tips to rub against her tunnel's insides and stroke over her clit. With his other hand, he was working over her nipples, tugging, tweaking, and even twisting. He could hear how she was gasping each time his tip slipped free of her muzzle, some saliva connecting his tip and her lips with each thrusting motion. Huffing, he tilted his head back as her lips popped nosily each time he pulled back. The feel of the velvety soft fur around her breasts, the way her chest was heaving under his body, and her warm, wet mouth applying suction to his cock was beyond description. He tried to keep focus on what his hands were doing, but... the mare is too good at what she did.

His balls tightened up as his tip filled with blood and mushroomed out as it popped free of her mouth. Roy huffed and pulled back before jerking his hips forward and tossing his head back. As he voiced a stallion's scream of pleasure as his cock began to spurt his seed. With his cock at the midway point between her cleavage and maw, Dakota caught the full force of the eruption on her face. The male's thick, white spunk splashed over her face, neck, mouth, and even on her breasts as he rocked his hips. She might have been able to avoid such as mess, but she had climaxed around his fingers at the same time. Her voice rose with his in a cry of joy as her pussy spasmed around the invading fingers, the female writhing under her stud.

Looking down at her, Roy felt a mild jolt of surprise at the sheer amount of his spooge on the mare and the surrounding area. Rolling her head to the side, Dakota gave him a coy smile as her chest heaved under the male. He knew just what she wanted to do and smirked. Getting off the mare, he held out his hand and helped her up. Dakota stepped in front of him and sauntered to the bathroom, her rear moving and her wrapped tail held high. Normally, he would give her ass a slap, but the way her scent fill his mind was just like when she was in heat. He was loving this, the sexual drive of that time of the month combined with the knowledge that she was safe to rut without using protection. As he followed her, he let his eyes travel down to get a look at her legs. If he leaned back a little, he could still see the puffy lips of her slit and the fresh juices over the dried mix of their earlier sessions.

Dakota slipped into the bathroom ahead of him and he could hear the echo of her hooves on the tile floor. Following her in, he saw the mare bent forward as she turned on the water and tested it. Holding back the desire to just fuck her there, he began to peek into bins. The first one he opened up held a single towel in it, a big fluffy one, but still only a single towel. Pulling it out, he dropped the towel onto the counter and closed the bin. His ear twitched when a soft thump caught his attention, making him take another look in the bin. Inside was a new towel which made Roy give a soft whinny at the impressive service. If he didn't love the country so much, he could get used to stuff like this.

She looked back at him and whickered as she twisted a knob and turned on the shower head, "Water's ready, Roy." She stepped into the tub slowly, keeping one hand on the wall as she tested the floor of the tub with her hoof. Like all horses, she had found out at an early age that hooves didn't work too well on slick flooring. She whickered and pricked her ears forward before looking at him and smiling. The floor had a little texture, like it was covered with those little no-slip things that you could buy for showers. He grinned at her and slipped in before pulling the glass door shut. When the door shut, the other nozzles turned on, spraying the two lovers with warm water from all angles. Dakota turned around and put her hands onto the wall, looking back at Roy as her tail flagged up and revealed her slit. As soon as she got in position, her slit tensed up and gave a wink, dripping some juices. That was all the invitation he needed, grabbing onto her rear and shifting a little before driving his member in up to its root. The pair shared a moan of pleasure, pushing against each other as the water ran over their bodies.

Holding tight onto her rear, Roy jerked his hips back and slammed in firmly. She let out a gasp and a neigh before pushing back into his body. Her feet shifted, the sound of hooves on the tub echoing around them as she spread out her stance. Resting her chest and cheek on the tile, she watched him with a low moan as she pushed her rear back and up a little. Wasting no time, he began to push into her body hard, his hips smacking against hers loudly. He could already feel a dull, throbbing pain around his thighs and crotch from the rough sex. He knew he'd be bruised as hell in the morning, and Dakota would be even more banged up. His muzzle curled up in a smile, knowing she was loving every minute of it.

The two horses worked together to try and increase the mutual pleasure. Of course they also had a standing challenge with Roy trying to get two orgasms out of the mare with a single fuck. Usually, it ended with her hitting her second peak about the same time he blew inside of her, so he could never tell when it happened. Not that he cared much either way, but it was always fun to have a goal.

His body pounded against hers as his hands squeezed and grabbed at her sides, thighs and breasts. Her body pushes back against his as she gasped and moaned, her hands sliding along the smooth tile walls. Arching her back, Dakota let out a moan from trembling jaws as the stallion's spire drove deep inside her again and again. With his cock spreading her needy insides, and his rough motions, she was in heaven. Already, her tunnel was starting to flutter around his thrusting member as her breathing got heavier. Roy knew what was about to happen and leaned down to bite her shoulder with his blunt teeth as his body slammed into her. She let out a squeal of pleasure and pushed back, her body shuddering as her climax shot through her. While she was orgasming, Roy kept pumping against her body, not letting her calm down too much as his hands held the mare up.

Standing up, Dakota shivered as she felt Roy's dick slip out of her. Turning around, she gave him a look and he smiled. As he stepped back and leaned against a wall, she turned off the water and watched him. Both horses were soaked, all the mess from the last few hours washed off their short fur. Walking towards him, she leaned in and locked lips with her stud. The blue Arabian male murred into the kiss as his hands slipped down to grab her rear and help her up. The roan colored Clydesdale moved up over him, using her larger size to help line him up before she pushed down on his cock with a gasp. Placing her hands on his shoulders, she wrapped her legs around his waist and felt his hands supporting her rear.

Roy straightened up, fully supporting the larger mare as she shifted and got comfortable. After mere seconds, she was ready and began to ride his cock. His hands helped hold her up and got her moving a bit faster on his lap as she rode him. Taking his time, he opened up the shower door and stepped out carefully. Dakota moaned and moved her head down, feathering her lips against his neck as the stallion began to show off a bit by not only holding her up, but moving around as she rode him vigorously. Panting, he could already feel the powerful need to burst inside her rising inside of his belly. Stomping his foot, he kept his slow walk towards the bedroom. His hips moved with hers, working his cock deep into her body and making her pants soon turn into squeals.

Finally, he made it to the bed and smiled at the mare as he huffed. Shifting forward, he slammed her back against the wall, drawing a gasp from Dakota as he pinned her there and began to pound his body against hers. His mare loved roughhousing and he knew just where to draw the line. Her hips wiggled and rocked against his, pressing her shoulders into the wall and pushing off of it. He widened his stance, letting him slam his hips up into hers hard as he grunts. Once more, their voices were beginning to rise in unison as their passions built to a frenzy. Her breasts were bouncing wildly from the combined motions, their pebble-hard nibbles rubbing against the short fur on his chest. Her ass was beginning to burn from the constant impact of his hips and the slaps from his hands. Dakota closed her eyes and let herself go to the pleasure. Tossing her head back, she gave Roy what he had been trying to get for so long. Squealing, she clamped down around his cock and began to orgasm again under his attentions.

Roy didn't notice, or even really care at the moment, as he drew a second climax out of her body. Pounding into her hard and fast, his ears were filled with the chaotic sounds filling the room. The constant, lewd noises coming from her body clenching around his cock, her pants and squeals, and his low grunts and whinnies as he pounded into her. He felt her body flutter around him then clench down with her climax, but it didn't register that he had finally reached his goal. Instead, he slammed in and let his voice join hers as he erupted inside of her body. Holding her close, he tilted his head up and panted at the ceiling as his hips rocked against hers, draining every last drop into her body. His member flexed and pulsed, the sheer volume of his seed coming out around his member and spilling over his legs and her pelvis.

Shifting away from the wall, he let her down and smiled at the mare as she looked at her stallion with a content expression. Following her to the bed, he laid down with a huff and felt his muscles slowly start to relax. Laying next to him, she let her head rest on his chest and gave a soft sigh before her eyes drifted closed.

[Several Weeks Later]

The little hormonal cocktail had gotten out of Roy and Dakota's system while they had their exhausted sleep. Leaving them sore, battered, a little raw, and very happy. After a day of rest in the lap of luxury, they had made the drive back to the farm and returned to their normal routine. Dakota had been feeling a bit off so they had called up Doctor Rashin and he had come to check in on her at the farm.

Dakota was kneeling on the bed, soft grunts coming from her muzzle as Roy held onto her hips and pumped his cock in and out of her wet snatch. The weasel was laying on his back, his clothes in a pile with the pair's on the floor. He was panting heavily and rubbing the mare's head as she bobbed her head over his cock, slurping noisily. They had talked him into taking some time off from the lab and having a small vacation at the farm. Of course, it was a lot easier when they put it in actions. Some people would say, 'When in Rome, do as the Romans.' Well, they said, "When on the farm, do as the horses,' or was it do the horses...

The doctor was panting as her tongue bathed his cock, rubbing the underside and working her blunt teeth against him gently. She let out a gasp and a moan around his hard member when Roy slapped her rear and slammed in fast for a second before settling back to his pace. Shifting forward, the stallion put a hoof on the bed, changing his angle of entry and making her moan happily. "So, Doc, what's the problem?"

Panting, Rashin looked at Roy, trying to understand how the stallion could keep talking so normally while taking the sexy mare. He had already had a taste of her lower lips and was amazed by how great it felt. He groaned, "Well, I send some... oh yeah... data to the... mmm... lab. They should be...ah! Should be calling me back soon."

As in on cue, the doctor's phone began to buzz and ring somewhere in the pile of clothes. Casually, Roy pulled out of Dakota, dug around, picked up the phone, and resumed plowing her before handing the weasel his cell. Rashin hit a button on the phone and fumbled with the controls before huffing, "R-rashin here." They all three listened as the person on the other end rambled off some scientific jibber-jabber about chemical levels and stuff like that. After a minute of rambling, the doctor thanked them and hung up as his back began to arch and his breathing picked up the pace. With a gasp and a shudder, he began to fire his load into the female's mouth.

Dakota drank down all his spunk then lifted her head and huffed, "What does all that mean, Doctor?" Her head tilted back as Roy got a handful of her hair and pulled her back into a kiss. They shared a long kiss before breaking it as they both gave loud squeals, climaxing together.

Rashin cleared his throat and watched them for a moment before shivering as the cool air from th AC blew over his moist cock. "Well, it appears when we adjusted the dose for Dakota's body size, we made a slight error." Both equines looked at him, their ears swiveling forward. He cleared his throat and scratched at his chin, "Apparently, the dose we gave you actually put you into heat, and now you are pregnant." He braced himself for a flurry of insults or shouting that would probably end up with him calling the company lawyer to get a settlement for them.

He wasn't really prepared for what they said.

Roy huffed, "Well, shit, that all? You had me worried for a moment, Doc." Pulling out of her slit, he walked around and rubbed her head as the mare licked his member clean with soft murring noises. "Looks like we can have a good reason to ask Steve to give us more space now, huh?"

She smiled at him and licked his member clean before pulling her maw back, "I don't know nothing 'bout raising a foal, though, Roy."

Rubbing her cheek, he smiled, "Hey, I think you'll do great. 'Sides, we can always ask Jenny about things. Doesn't she have a kid of her own?" Laying back, Rashin watched the pair with a little smile and a soft sigh as he slipped his hands behind his back.

A throat cleared near the door and all eyes turned to look at a nude Doberman female with a leather outfit on that showed off her smiley face nipple rings. Fran grinned, "If you are ready, Doctor, I believe its my turn with you." She licked her lips and tapped a crop against her hand before looking at the horses. "You two want me to spread the news?" She got her answer when Roy launched a pillow at her and hit her in the muzzle, making the female growl and pretend to look menacing before leading the doctor out.
