Nelson thought he could get away, but Mr. K has a nice surprise for the young horse...


Hey everyone!

This is an idea that I had a while back, thinking on the cliché of tennis instructors banging their middle aged housewives students; I decided to give it a flip! Then, while thinking which species should featured in it, I remembered that avatar?user=81389&character=0&clevel=2 Nelson Darkstar is an enthusiast of tennis and decided to feature his horse fursona in it ! Hope you will like it folks, please let me know with a fave, a comment or a vote!

I thank avatar?user=48220&character=0&clevel=2 Gritou for the editing and, this time, avatar?user=81389&character=0&clevel=2 Nelson Darkstar for letting me borrow his character :3

"Am I doing it correctly, Nelson?" The chubby cow mooed seductively, eyes lashes vainly fluttering as she looked at the tennis instructor while swinging her racket.

The blonde maned horse circled the portly woman, examining her moves and body; especially the body. While obviously middle aged, the bovine had that kind of chubbiness that actually enhanced her generous natural curve, in a way that was quite attractive to the horse.

"Almost Mrs. K., you need to bend a bit more... Let me show you." The black equine told his trainee, closing the space between them with one stride of his long legs. Bending his back a bit, he embraced the older cow from behind, pressing his white clothed-body against her D&G gym clothes.

"Oh yes, show me Nelson!" The bicolored bovine chirped excitedly, pressing her impressive booty against his crotch and his fully engorged erection. Bitch giggled at the discovering, wiggling her butt as the horse accompanied her moves, demonstrating how to hold her racket. How he would love to hold her rack right there and then...

Raising his eyes, the young horse found the big bull where he had left him, watching them from a bench outside the court with a grim expression on his muzzle. Mr. Keruac's presence was the main reason why his paws hadn't even brushed those impressive knockers, and why he was keeping a flirt-less, professional demeanor.

Of course, the vapid cow was too stupid to tone down her horniness, practically feeling up the black equine at any opportunity and using the sickly sweet voice of a teenage girl with a crush. Not that Nelson cared if the housewife was so stupid to flirt with a young, fit fur in front of her husband's very eye; after all, it was none of his business.

The thought didn't really ease his mind as his eyes shifted from the practicing cow to her obviously infuriated husband; though, to tell the truth, he wasn't watching over the bull just out of preoccupation. He had seen him standing just a the beginning, but the brown furred male was astonishingly handsome, tall and broad shouldered, a muscled frame that his almost juvenile t-shirts and shorts failed to hide.

And the small hint of a gut just made the horse's legs weak, who was wondering how it would feel to have it pressed against his back as he got fucked by the middle aged bull... Which made his erected cock ache even more for release. Unfortunately, it seemed likely all he would get was a quick pawjob, and just that...

"Nelson, I feel like you should show me again!" The thrilling voice of the cow interrupted his train of thoughts, bringing him back to reality as he thorn his eyes away from her bovine spouse.

"Oh no Mrs. K, you were doing it just fine now!" The horse was quick to answer, regardless of the truth. He glanced quickly at the watch on his wrist, thankful that the lesson was at its end.

"But I am not doing it right, I need your guidance!" The cow whined, obviously wanting to feel those young muscles all over her. Usually, he would have obliged quickly, but a pair of jealous eyes was stopping him.

"You needed just a few corrections Mrs. K, nothing more." Nelson reassured her, showing his teeth in a charming smile while dismissing her. "You mastered it, next time we will try out the service!"

"Oh dear, the hour passed already?" The middle-aged woman pouted, clearly disappointed by this cruel trick of time, and probably unsatisfied by the horse's behavior. Her flicking ears were a sure sign of her annoyance, but she had to bear with it this time around.

"Yep! But there is always next time!" He said cheerfully, his tail swishing behind him. The young instructor sure hoped to have the cow all for himself, her husband was eye candy but a serious cock blocker...

"Oh yes, next time!" The bovine echoed him, swiftly getting closer to him and standing on the tips of her hooves to plant a big kiss on his dark cheek, dangerously near to his lips. And dangerously long too, so much that the horse wondered if he needed to shove her away himself.

Gladly, he didn't have to, the portly cow getting back to her proper height and walking away, all the while waving her paw in a salute. Nelson waved her back, watching as she joined the handsome bull. They seemed to be a mismatched couple, her short and wide, with researched clothes; him tall and positively buff, with street clothes that replaced his usual suits during the week-ends.

Nonetheless, he found both of them very attractive. The black horse just loved a woman with some meat on her, and huskiness on his men, and those two just incarnated it. Too bad that they were going to have a fight, if he interpreted the metaphorical thunder clouds above the bull right, but that was beyond his car.

Giving his white-covered back to the bovine couple, he proceeded to gather the balls spread across the court's synthetic grass, bending over to reach them. He wished he could get a photo of himself like that, he knew how good his rump looked in those white tennis shorts, and that would make a good pic for Gropr...

Suddenly, he felt a presence looming behind him, a big shadow appearing just before him. That almost startled the black equine, but he knew better than jump straight up; he had a reputation to defend, after all, and being a scaredy horse would hurt it and his chances to get laid.

So he took his time to straitening up, making sure that his tail didn't swished too much as he did it. The equine masked his surprise at finding that the fur who had approached him from behind was none other than Mr. Keruac, alone, his wife nowhere to be seen. Being so close to the muscled daddy made his horsie cock jump in his underwear, despite (or maybe because of) the grim expression on the handsome muzzle.

"You're Nelson, right?" The brown bull rumbled as he towered over the equine. He wasn't that much taller than him, actually, but he had that kind of presence that gave him an extra foot in height... That aroused the blond-maned horse, even if he should know better than sporting a boner while being confronted.

"Yes! Mr. Keruac, right?" The young instructor answered with a smile, thrusting his paw forward. His paw remained there, the sign of salutation ignored as the bigger male grimaced at him; to his honor, his smile didn't wavered away, though a thin veil of cold sweat started to form on his fur.

"There is some place private where we can talk?" The bovine's question was more of a demand that didn't leave room for a no. The bull was truly intimidating, even in such casual clothes, reminding Nelson of his PE teacher back in high school.

His tail swished even more in nervousness, his ears flicking a bit too. There could be many reasons why the older fur wanted to see him in private... Not many very pleasant, considering his rough tone and demeanor. "I have a small office. This way." He managed to say without stuttering, brushing against his shoulders as he walked to the exit, leaving the balls in their bucket on the way out.

Mr. Keruac followed him without a word, a bigger shadow that trailed behind him. Usually, he wouldn't mind that, since it was always a prelude to some hot action... This time, though, it was not going to end up like that... Unless his instinct was right...

The tiny sparkle of hope accompanied him as they approached the low building that housed the locker rooms, and also the small rooms that passed as offices for the instructors. Stopping in front of what passed for his office, the tall horse fiddled with the keys until he found the right one, opening the door to the poorly lighted and heavy-aired space. The horse turned to face

"So, Mr. Keruac, what do y-" Nelson couldn't finished the phrase as he found the other male upon him, just a few inches away. His paws were clutched in fists at his side, as if he was about to punch him if the bull hadn't been surprising his anger; the horse tried to back away but his retreat was stopped by the small table that passed as his desk, trapping him with the furious bovine.

"Yer fucking my wife, ain't ya boy?" The older man growled, his hot breath washing over him, slightly smelling of cigar. The horse boldly held his position, staring right in the bull's eyes, trying to discern the emotions of his assailant; but those were like dark pools of still water, unreadable, with just a flicker of fire of emotions burning in them.

"I don't know what you talk about, Mr. Keruac. I assure you that-" The black equine started saying in his most diplomatic and soothing tone; he got confronted by an angry, jealous husband (or wife) at least twice a month, and he had developed a sort of method.

"Don't fucking lie boy!" The bull interrupted him, unaffected by the horse's voice, drawing so close that they were practically kissing.

"I'm not lying. Nothing happened between me and Mrs. K." Nelson said, trying to sound bashful and nervous this time, hoping that it worked better than be direct and proud. Once again, the approach didn't work as it should.

"You're banging her. She always comes back from these silly lessons satisfied, barely even giving me a blowjob!" The brown bovine roared, veins appearing on his thick neck. The tennis instructor sighed internally: blueballed husbands were always the hardest to deal with him.

"Tennis is a very tiring activity; your lady might be just too out of stamina for more activities." He tried to explain, his ears flicking and eyes darting; he was feeling just partially the fear he was showing, he was a big horse, after all, if it came to throwing blows he would for sure not go down easily....

"Fuck the stamina! You think I don't know what is the small shrewd smile my wife come back is?" The bull continued in his tirade, angry as ever, his body know pressing against the horse's as he got closer; Nelson felt a mound pressing against his crotch, one that couldn't be mistaken for anything.

The horse smiled, his early suspicions being confirmed by that small (or not so small) detail, his fear evaporating and being replaced by cockiness. "I see. I can't hide it anymore."

"So you don't deny it anymore!" The muscled man grunted in satisfaction, looking down on the cocky horse, his erection pressing even more against that young and fit body.

"Oh yes. I fuck her. Here, in this office, on this table." Nelson started saying, his grin widening with each new word, his chin held high in pride. That only rekindle the other man's emotions, though the light in eyes was far from being of anger, as the sizeable hard on proved to him.

"Damn pretty boy, you taunt me with that!" Mr. Keruac rumbled, in all appearance ready to beat the shit out of the disrespectful fur. But the horse knew better, he knew that he was going to get something, and that something surely wasn't a beating.

"You saw how much she lust for me... Always pressed against me..." The black furred man continued, very much liking where this was going. His own cock had regained its stiffness, something that the bulkier man shouldn't miss as he was practically glued to the other fur, even though his arms were still at his sides.

"You... you... PUNK!" The bovine was utterly in dismay now, not knowing what to say, nor how to properly insult the horse; his brain was lacking blood, all gone to his more manly parts. The older fur liked the idea of his wife being fucked by someone else... He liked this horse... Oh yes... And maybe with another little push...

"That cow is such a fine piece of ass... and so loud... she moos so much when I eat up her pussy, before shoving my cock in." Nelson wanted to add more to the description, maybe how her tits slapped as she rode him, but a sudden pressure on his shoulders stopped him, two big paws grabbing them and strongly pushing him down.

The young equine let him do that, going on his knees as gracefully as he could, facing the big, prominent bulge in the bull's shorts. The musk hit his nose strongly, Mr. Keruac must have pre-ed a lot during their conversation; such a smell went directly to the instructor's head, his wide and long tongue licking his lips in lust.

"I... have a better use for... your insolent tongue!" The muscled bovine was saying, as he tried to unzip his pants with one paw, the other keeping the horse in his place; the young man would have helped him out, but it was clear the other wanted to be in full control. So he waited, as the bull managed to lower his pants and boxers, his springing cock almost hitting the dark furred horse's muzzle.

His mouth watered at the sight: a true bitch buster, nine inches or so, thick as a can, aimed directly at his muzzle. His own pridehood throbbed in his white pants, and he felt the need to have that thick cock in him; but his head was clear enough to know he needed to act his part. "Mr. Keruac, w-what are you doing?" He whined, ears properly laid down, feebly trying to get free from the strong grip.

"I'm teaching you a lesson, pretty boy. Now open wide, let's see if you suck cock as well as you eat pussy!" The bull bellowed, thrusting forward his dick, angled with his free paw. The equine didn't protest, opening his mouth wide to accept that thickness, his lips locking themselves down as the bovine thrusted in.

Nelson relaxed his maw and let the bull set a pace. His muzzle was long enough to swallow such a musky goodness without gagging, the tip barely scrapping against the back of his mouth; plus, he had enough experience in deep throating not to have problems even with bigger cocks. The bi-curious bovine set his paw back on the shoulder, moaning as he started to muzzlefuck the younger man right away.

The black horse wasn't idle, even if he couldn't bob his head as he would: his tongue knew tricks, wrapping around the moving length, stimulating the cockhead, slurping loudly to enhance the hotness of the action. With each thrust two brown furred balls slapped against his chin, properly tennis balls sized, as the bull fulfilled his secret desire.

"Suck that bone pretty boy... Feel your punishment!" The bull rambled as he thrust in the willing muzzle, still going with that act. Nelson wasn't going to complain; those words were a turn on by themselves, his horsehood aching to be played as he delved his paw in his pants, slowly starting to pleasure himself.

This kind of scenario had happened to him before, the horse starting to reminisce as the thick pole conquered his long muzzle. Married guys using the pretext of punishing him for sleeping with their wives... An excuse for them to fuck the horse boy that he didn't mind; if it pleased them to pretend they weren't giving in to their homo urges, why not going along?

This bull was one of those types, muttering "pretty boy" as he fucked Nelson's muzzle, his paws still lodged on his shoulders. He must have been excited for a great while, watching the object of his lust being leered by his wife, while he wanted to do the same... Now, he got the opportunity, as his cock slipped between those big lips, the skilled tongue of the horse worshiping it and caressing it.

Nelson moaned around that piece of manly pole as he started to jerk himself off at a faster pace, his paw being carefully to stimulate his flare. He loved orally pleasuring someone, be it female or male, and the repressed passion of this daddy bull just added to it, the room being filled by the wet slapping of balls on a chin.

Slurping loudly, the black equine felt his orgasm approaching fast, something he would welcome gladly; but Mr. Keruac seemed far from being done, barely mooing as he shoved his cock in the younger male, no telltale signs of him being close to bust his nut... Maybe he should slow down his jerking and wait for the bull to spill his sweet seed in his mouth or...

That delicious cock disappeared from his muzzle while he was lost in thought, the two strong paws shifting their positions to under his armpits, commanding him to stand. The horse rose on his feet, panting, a trickle of saliva flowing from the corner of his muzzle, his white shorts slipping down thanks to the weight of his boner and leaving his ass bare to the air, as he hadn't been wearing any underwear that day.

The muscled fur looked at him, his paws keeping the slightly shorter guy close, their hard-ons pressing against each other now. Nelson refrained from making a joke, he didn't want to ruin the mood, especially since their muzzles were so close... maybe he should dare and kiss the bovine... Maybe he would like that.

"I'm gonna make you feel what my wife feels when you fuck her. Pretty boy." The brown furred male spitted the last bit like it was an insult, his rough paws turning the nibble horse around and pushing him on the desk.

"W-what?! No! At least put some lube!" The horse protested, his tail swishing; this time he wasn't acting, he knew he was good at taking cocks, but he needed at least some lubrication! He tried to get up, but the bovine kept him in place easily with one paw, the other grabbing his tail and holding it high, baring his hole.

"Shut up pretty boy! What a nice pussy you have there..." The cheating husband chuckled, his eyes surely fixed on the winking muscles. Then a pop resonated in the room, just before something cool and sticky hit it, sending shivers all along Nelson's spine.

"Damn bastard, he brought it!" He thought, recognizing the liquid by feeling. That would help a lot, but he could use a good fingering before being buggered.... He was about to tell as much to the domineering bull when he felt the tip of that massive cock posed against tailhole, kissing it but not entering it.

Nelson opened his muzzle but only a loud groan made it out of it, as the bastard bull pushed his cock forward, the lube letting it slips in easily. The tight hole let it in with some protests as it hadn't been stretched, inch by inch of juicy bullhood invading the poor equine, who couldn't do anything other than trying to relax and take it like a man.

Luckily, the black furred instructor wasn't a rookie at taking cocks, so the whole length entered him with just a small discomfort instead of pain, bit by bit, until the thick tool bumped against the prostate of the horse on its way in. Pleasure washed on him, making him moan as his own lonely cock jumped, regaining some of its hardness that was lost at first entrance.

"Looks like I found your g-spot." The brown bull taunted him as his crotch flushed against the lustrous black asscheeks, his paw finally freeing the equine's tail which went to rest on the side. Nelson was just half listening, his whole attention was on the big cock embedded inside him, the cause of so much pleasure; he was past the point of being coherent and talking back to his partner, all he wanted now was to be bred roughly, to be fucked as hard as possible.

Mr. Keruac stayed put for a few seconds, probably enjoying the tight warmth around his sizeable pole. He shifted a bit before finally retreating his member, as slowly as it had come in, waiting for just the tip to be in before shoving the whole thing back in the hole, all the while eliciting loud moans and whinnies from the horse.

That was the start of the rut. The bull had been lusting over the horse for a great while, watching him flirt with his lady, jealous that the cow was getting to fuck him; but now it was his turn to own the pretty boy, and he wanted to make the most of it. Or so Nelson guessed in his last moment of clarity before all turned in meaty action.

The bull delivered what his appearance had promised: deep, strong thrusts wrecked the poor lucky equine, stretching his hole to the limits, poking every nerve down there, making his cock throb madly and oozing a pool of pre on the floor as its owner got fucked. The lack of preparation was actually enhancing the pleasure, Nelson being utterly lost in the world only bottoms knew.

The thick member went in and out of the young instructor, as the bull grunted over him, his big paws grabbing the horse's asscheeks to spread them open and, even, to spank them as he got used. The only sounds in the room where the grunts from the two males and smacks of flesh against flesh, of balls against balls, so loud that surely was declaring what was happening inside that room to whomever was outside.

Nelson couldn't decide if the brown ruminant was an expert at butt-fucking or an extremely lucky amateur. His thrusts weren't mechanical, never going in the same direction, that cock being shoved in different angles that only helped stimulate different parts of the horse's ass; and those paws resting on his butt were just helping, manipulating the horse from the outside, giving him even more pleasure.

The horse's wide tongue lolled out of his mouth as he got bred. He liked screwing big assed ladies, sure, delving his hoss cock deep in them: but what really liked, what was always assured to make him horned up, was the prospective of having a thick cock thrusted deep in him, of being used by another male.

That, unfortunately, meant Nelson was quickly coming close to his climax, his cum churning in his balls and waiting to be released. He was most sensitive when fucked, and cumming paws-free wasn't a rare occurrence. To top it off, he had been saving himself for Mrs. K, he was never bound to last too long...

The bullhood poked his prostate one time too much, triggering the orgasm of the hoss, who let out an almost deafening whinny as he came. His cock throbbed hard as it shot the white seed all over the ground and even on the horse's pants, all of his body spasming in pleasure, his own ass going out of control and clenching hard on the invading object.

The bigger male continued fucking the spent horse restlessly, shoving his big cock deep in him without sign of stopping, the orgasm not triggering his own. The continued stimulation of his prostate was almost painful now that he had cum, but still pleasurable, keeping the horsehood still hard and swigging with each thrust, smearing cum on his white shirt.

Nelson idled wondered in his afterglow how long the middle aged man could go on, shivering at the thought of cumming twice from being fucked by him. That bull really was turning to be a keeper... But time was running short for the both of them, as he felt the amazing presence of that member disappear all together along with one of the paws, leaving his hole gaping open for a few seconds.

Tiredly, the tennis instructor turned his head to look at the bovine, standing behind him and frantically jerking his big cock. He must have been pretty close too, since it took only a few movements of his wrist before the muscled fur came without much sound, rope after rope of cum being shot through his fist and landing all over the bent horse, even hitting him on the muzzle.

Panting, the bull slowly pulled up his pants and underwear, stuffing his still hard cock in them, hidden by the cloth. "I hope you've learned your lesson today, pretty boy." Mr. Keruac said between deep breaths. "Hit on my wife again, and I will be forced to repeat this lesson."

With that, he stooped outside, closing the door loudly behind him. Nelson was left alone, slowly recovering by the unexpected buttsex he had been subjected to, but feeling quite satisfied. It was hard to get himself up again, the movements pulling muscles in his abused hole, making him wince for the discomfort.

Stretching his limbs a bit, he licked off what little cum had reached his muzzle, savoring the strong musky taste of the bull for the first, and hopefully not last, time. The horse tossed away his cum--stained shirt and grabbed some spare clothes out of his back, chuckling to himself that Mr. Keruac would surely find a reason to repeat this, whether real or not.

"I wonder how long it will take before a threesome with the Keruacs..." He wondered aloud, as he prepared himself for his next lesson.
