Septimus was underneath a muscle car, his working carefully as he unscrewed the oil cap. He quickly moved out of the way, the thick and viscous liquid leaking out into an open container. He wiped his brow in satisfaction. The Pontiac that was brought in was nothing short of classic muscle and the bull was always a fan of such archaic displays of power. It was a Firebird; one of his clients a salt and pepper horse like himself.

Grabbing an oil covered towel that was off to the side, Septimus wiped his hands. He gave a huff and his silver nose ring wobbled between his nostrils. Where was his valuable employee at this time? He slid out from the undercarriage of the car and made sure to watch his horns as he made his way out. Having an ancestry from Texas, his horns had that nice curve to them and the fur that he had that wasn't in oil was a blackish brown color. It was a much darker color than his son who had a pure brown fur color. He got that from his mother.

Tufts of white fur popped out from his overalls on his chest and if someone would have caught him changing in the locker rooms beforehand, they would see it cover over his pecs before dipping down into the V of his pelvis.

His large maleness and balls wobbled between his legs as he got up off of the cart. A lot of the men and women he was with would describe him as "well endowed." Having a breeding bull heritage did have its advantages...and disadvantages. Barely any underwear would be a comfortable fit on him while he was in his overalls and the blue, indigo color that faded over time had rips and tears near the crotch area for...obvious reasons. Sometimes, the excitement of doing his job and being covered in sweat and musk after a hard day of work was just too much of a burden to bare.

Septimus smiled and adjusted himself as he made his way back to the employee workroom. He could hear the sound of laughter and his ears flicked. The silver loop that was through one of his ears matched the color of the bar piercings in his nipples. The two perky nubs stuck pressed forward against the material of his mechanic overalls and his pecs would have bounced in the tight material if the muscle that ballooned outward did not keep them in place.

Walking into the employee workroom, Septimus huffed. His dutiful employee, who had only been a member of his garage for a month, was watching a video on his phone and giggling up a storm. The donkey's overalls were zipped down, casually showing his own open chest. The grey fur that dipped down into the donkey's abs and Septimus could see a tuft of fur poking up from the man's crotch.

He was young which was only highlighted by the fact that it sounded like he was listening to some dumb internet fad. Truthfully, Septimus did not know but the irritation he was feeling started to begin to bubble inside of him. His ears flicked, his nose huffed, and his tail began to flip back and forth behind him.

"Sam..." Septimus sighed audibly and the donkey snapped to attention. Sam tried to hide his phone down between his legs, a red blush crossing his face.

"I have spent the last thirty minutes on the Pontiac. What have you been up to?"

When Septimus walked forward, he practically dwarfed the younger and smaller jock. The donkey crouched in the chair, his chocolate brown eyes looking upward like he was caught rummaging through the pantry late at night. For all the muscle, the donk was the epitome of beauty over brains. Septimus's own blue eyes locked with Sam's own.

"I-...I..."

The donkey's gears in his brain started to turn and a sheepish smile crossed his face. The bull thought his heart skipped a beat. It was hard to be mad when he got all flustered. Sam's face started to turn a shade of red and it wasn't because the lounge was hot. Beads of sweat rolled down Sam's front side and his neck. The overalls had small dark spots where precipitation had gathered.

Septimus continued to wait for an answer and he just continued to stare. The donkey was starting to fiddle with his thumbs.

"Yes?" Septimus said with an air of expectation to his voice.

"I thought I would take my break a bit early. It was just so hot in the garage and I stepped out to grab water," Sam said as he looked up at Septimus, blinking innocently. He hiked a thumb to the water cooler. Five different paper cups were scattered around it.

Septimus bit his cheek. The dumb donkey could have just used the same cup but he had to get greedy. The bull made a mental note.

"And...you just forgot to come back?"

Sam's eyes flicked left and right and he went back to fiddling with his thumbs. He appeared so cute and innocent. Septimus's eyes wondered, however. They started to scan over Sam's form. Especially the fact that the zipper of the donkey's jumpsuit was practically still down and there was a rather large wet spot right at the crotch.

"Well, not exactly..."

"Uh huh," Septimus said and he started to tap his foot. Sam blushed an even deeper red. If the employee of the month thought he was going to get out of this little blubber by acting all shy, then he was up for a rude awakening. Part of Septimus wondered why he kept the aloof jock around.

Septimus's eyes started to move lower, particularly around the wet spot. It formed a large, dark circle and Septimus's nostrils instinctively flared. A musky scent reached his nostrils. It smelled of male and sex. The bull had smelled it before on many occasions and just the whiff he got of it sent a tingle up his spine. Septimus continued to keep his composure, his arms crossing as he watched Sam squirm.

The bull stepped forward now and lowered the distance between them even more. Sam's eyes darted around. From the floor, to his boss, to his boss's crotch, up the boss's abs, up to his mighty chest...

"Eyes here, pup," Septimus commanded with a bark to his voice.

"...."

When his employee disobeyed, Septimus cupped Sam's chin. He moved the bottom of the donkey's muzzle up until the brown eyes were staring right into his. Sam's tail flicked excitedly against the backboard of the chair and the black tuff made circles around. Septimus still kept a neutral expression.

Sam was like his son. The younger stud could barely keep his cock in his pants until Septimus taught him discipline. This would just be another son. When he caught Max balls deep in his first man, Septimus knew he had to step in and show the breeding bull how to properly mount up. All that it took was a night on the couch, naked with a couple of beers, and some appropriate visual stimuli. Septimus had his son breed a fleshlight nice and deep. Even showed him the ropes by taking the toy away from him from time to time to fuck it full and deep with his own cock.

Septimus smiled warmly down at Sam now.

"That's a good boy. Eyes up here."

Sam obeyed and immediately his overalls tented. The radius of the wet spot on Sam's increased when the donkey's flare bloomed outward. Just inside, a white jockstrap kept everything together and Sam's cock barely had room to breath as it was pushed up and throbbed against his abs.

"Why did you really come to the employee lounge, hmm?" Septimus asked quietly, his voice velvety and smooth.

Sam could not find the words to speak. The zipper of his overalls was starting to bite into the underside of his cock to give a tiny bit of pinching pain. It wasn't a bad feeling by any means but it certainly was not pleasurable and reminded the donkey of how turned on he was. The jock said nothing and swallowed. Septimus chuckled as his hand felt the muscles of Sam's throat work the saliva downward.

"You can tell me, son," Septimus said softly.

The donkey opened his mouth as if he wanted to say something but then stopped. Septimus patiently waited and soon Sam was talking. It was like a dam burst and finally let the torrent of water it was holding back out and through.

"Because I thought about our first time..."

The bull's nostrils flared again and the smell of the donkey's pre triggered the particular memory. It was a particularly hot June day and the two decided to take full advantage of the private garage. They both stripped down, Sam suggesting it. Septimus remembered watching that lean but muscular jock body flex and move. The sweat only highlighted it and when Sam caught him looking, he would cheekily flick up his cropped tail and flex his arms and slap his ass.

The smell of pure musk was all it took. The jock knew what he was going for. Septimus fucked the truth out of the donkey and the stupid foal admitted about the gay vintage porn that he found in Septimus's office. The dumb stud wanted to be rutted like a 80s porn star and fucked on the hood of the delorian that came in. Septimus gave him everything. He ate Sam's hole out for what felt like hours and then sloppily made out with the jock. Sam had done his research and was prepped. Told him he had played with a plug for a week to prepare himself for Septimus's fat cock and all nine inches of pure stud.

When Septimus popped in, the donkey could only bray like he was in heat. They had to repaint the car due to the scratch marks but Sam was more than happy with staying late. The two kissed between each coat and Septimus had the donkey's legs up over his shoulders in a mating press in the time between drying, too.

Now, Sam was looking up at Septimus with the same needful look he gave him and the glance told the bull everything he needed to know. Using his thumb to stroke across Sam's cheek affectionately, Septimus's eyes scanned over his employee. Moving his muzzle closer until his lips were almost touching Sam's, Septimus gave a broad smile when the donkey started to shift in his seat and leaned forward needfully.

The bull moved just far enough back that their lips did not connect.

"What makes you think I shouldn't punish you? I should just let this simmer..." Septimus said with a sadistic purr to his voice, his right hand moving along the donkey's thigh and feeling the muscle under the overalls

"I should let you think about what you have done wrong."

Sam whimpered, his cock throbbing upward and he reached down to grab the zipper of his jumpsuit. Septimus quickly brought his hand forward and gently wrapped it around Sam's hand and the donkey's cock. Hips naturally rolling forward, Sam dutifully kept his hands right on the side of the chair.

Breathing hitting as Septimus's lips moved to his neck, Sam's hands gripped the sides of the seat and started to squeeze when his lover's blunt teeth started to bite harder into his neck. If Septimus could, he would bottle the sound of Sam's breath jumping upward. He pulled away from the bite area and then licked across the wound. It would not bruise but the grey fur was covered in bull saliva from Septimus's thick tongue.

Septimus's hands moved away from the donkey's abs and thigh and began to move up and around Sam's thick chest. His hands grazed across Sam's pecs and around the jock's perky nipples. Septimus leaned forward and smiled. His warm breath kissed Sam's cheek and the mechanic groaned.

"Can I please zip down my jumpsuit, sir?" Sam asked and his eyes sparkled. Septimus chuckled and took both of Sam's nipples between his index finger and thumb. He started to roll the nubs between his fingers and pulled away for only a moment to flick the nubs to life before coming back to them. Sam was putty in his hands, his body starting to react and heat beginning to pour off of it.

"I will determine that," Septimus said with a growl to his voice and finally brought his lips up to his lover. The two kissed softly. The bull pulled himself up to Sam's hips and straddled him. Septimus's rump was right up against Sam's cock and he teasingly started to slowly grind into the donkey's thick cock. Septimus grunted when two hands moved down towards his rump and squeezed the muscular cheeks and the boss moved his hands off of Sam's nipples to grab the young and eager jock's wrists. He gently moved the hands towards the front of his thighs.

Sam squeezed into the muscle. He could feel the tight muscle and how the sinew flexed and moved underneath his touch. If Sam wasn't occupied with Septimus's muzzle, he would have been worshipping his boss as eagerly as he did on the first day they made love. Although their carnal passions were ready to explode out, Septimus took it slow and sensual. Their tongues explored each other's muzzles and Sam's tongue went over the bull's teeth. He enjoyed how they felt on his sensitive tongue and the donkey's cock throbbed cushioned right against Septimus's rump.

Begging with his body, Sam's hands squeezed encouragingly when Septimus went back up to his nipples. Their soft and intimate kissing brought squeaks and groans out of Sam and when Septimus's hands started to move back down Sam's abs, the donkey's tail started to flick excitingly behind him. Pulling away from the kiss, Septimus smiled warmly down at his donkey pup.

"You want your cock free?" Septimus whispered and nuzzled against his lover. He got up off of the donkey, bringing a trail of saliva on his lips and some pre on the backside of his overalls.

"Yes sir," Sam groaned and thrust his hips upward, his hard cock flopping around. "Please...."

"Good boy," Septimus said with a smile and brought his hand forward. He quickly started to unzip down. The zipper traveled lower and lower until it made it to the donkey's crotch. Full, sweaty and musky donkey balls flopped out of the overalls and Sam blushed when Septimus grinned down at him.

"Such a big stud," Septimus said as he brought his right hand forward. With his palm facing Sam, Septimus gave his lover a knowing look.

Sam smiled, reaching forward and grabbing his lover's hand. The overalls fell off onto the chair which left him standing naked and exposed. Septimus put one of his hands possessively on Sam's right asscheek and squeezed it lovingly and brought his other hand on the donkey's right hip.

Still beaming from ear to ear, the jock's cock stood straight up at attention. He watched his boss carefully. The bull was still in his overalls but the zipper had dropped lower which exposed more of Septimus's chest. Mixed in with the dark fur were tufts of grey along the chest which showed his age. Although he would be labeled a daddy, Septimus liked to think of his breeding capabilities like a fine wine.

Ballooned pecs now exposed along with perky nipples pierced with a silver bar, the artificial light brought out the glint of silver that matched the fur around his nipples and down his chest and abs. When Sam took a look at Septimus's horns, his eyes widened.

"Wow, those look new," Sam said with a sparkle of enthusiasm to his voice when his eyes fell on the large, curved horns tipped with silver. They sparkled in the light just as much as the nipple rings and gave Septimus a royal look. Sam stood as high as he could, reaching upward to begin to twiddle with the tip. Septimus brought his head down so Sam did not have to reach upward awkwardly and chuckled when Sam's cock throbbed between his legs as his hand moved from the polished horn up to the well-maintained silver.

"You like it?" Septimus said with a cheekiness to his voice.

"Yeah..."

Septimus gave a pleased rumble when hands began to move towards his pecs and began to flick over his nipples. Sam placed his muzzle up right between Septimus's large pecs, the two muscles on either side and the bull flexed them. The donkey had a pleased look on his face as the two mounds lightly squished his face and then the bull bounced them. Sam's head shook gently.

"I can't believe you can do that, stud," Sam dreamily sighed as Septimus continued to flex his body. As a reward for the comment, the bull grabbed the zipper on his jumpsuit and started to bring it slowly down to his crotch. His thick cock slumped downward, the base of it just peeking over the tight overalls.

"Such a good donk jock," Septimus said as he placed a hand on the back of Sam's head and scratched it affectionately. "Why don't you help me out of my clothes?"

Sam shot off of Septimus like a bullet from a gun. He walked behind the bull and Septimus allowed the donkey to pull his arm out of the overalls. If he wanted to, he could have prevented every move that Sam made but he was so into the eagerness of his lover that the thought of being an obstacle to Sam's needs never crossed his mind. Septimus walked forward and his arms were easily pulled through.

Sam quickly made his way to the legs and started to slowly strip the bull out of it. Little by little, more of Septimus's endowment started to show. The bull's powerful rump and legs were on full view and the donkey was salivating as the little tail flicked up and showed off his rump. He brought his hands forward and started to rub over the globes and Septimus flexed them teasingly. The bull's thick thighs held between them two round, full nuts that were held in a large, leathery sack. A nice smattering of grey fur mixed with black right along the bull's taint and up along his balls. Moving to the other side, Sam started to continue to strip Septimus down and got a full view.

To Sam, it looked as if the cock went on forever. Popping out of the overalls, it flicked upwards and pre splattered across the room and a bit got on his naked fur and muzzle. Sam could practically smell masculinity and his tongue licked upward to taste the pre. Spreading his legs, Septimus gave a pleased smile.

"You've done so well," Septimus cooed and brought his hand down to place it on Sam's cheek. He rubbed it affectionately once more. "Keep going. I'll give you your reward soon."

"Yes sir," Sam said, his voice dripping with lust.

Bringing the overalls all the way down to the floor, Sam was now kneeling before Septimus. The bull stood over him, his body practically blocking out light and casting a large shadow. The mix of oil, sweat, and musk that was radiating off of Septimus's body reached Sam's nose and threatened to completely paralyze him. If he had no self control, he would have dived forward. However, Septimus called the shots. If the boss wanted him to eat him out, he would. If the boss wanted him to cum, he would.

Two nipple rings glinted in the light, bringing Sam's eyes right back to Septimus's eyes.

Septimus was hard. There was no doubt about it. He stood at attention, his cock pointed forward and Sam was drooling. Every time the muscle bound stud moved, his cock would wobble temptingly above him and his balls would shift along with that beautiful piece of meat.

Septimus walked forward, Sam's head now flanked by two thick thighs and Septimus said one word...

"Lick."

Sam dived in. His tongue immediately found the earthy musk that was trapped within the jumpsuit moments ago. Saliva mixed with sweat and precum as the donkey started to lick and kiss everywhere. Septimus grunted approvingly, squatting a bit when the nimble tongue found his hole and started to lather it in spit. The movement was sending shivers up the dominant bull's spine and straight down to his cock.

"Fuck, you are so good, stud," Septimus sighed lustfully.

Giving a groan in response, Sam continued his onslaught. So much so, that the drool that covered his mouth and the lewd slurps coming from between Septimus's thighs was the only thing the donkey cared about. He wanted this daddy of a stud to be more than happy with his performance and each compliment that Septimus said fueled him.

Sam grabbed Septimus's tail, hiking it up and diving in between the bull's two muscular globes. His tongue licked across sweat and earth and he smiled lustfully when he made it to the bull's warm and winking star. He licked across the soft flesh and made sure to gently apply a bit of saliva to it.

The donkey knew he would never fuck such a stud. His body would be used by Septimus and he would enjoy every second of it. Sam made his way back towards the front and his nimble tongue followed back over Septimus's taint. He sucked on one of Septimus's testicles. The other one flopped over his nose and he could only inhale the masculine scent while he licked and suckled loudly on the other. '

When he popped out the right orb, he slowly moved to the left one. He gave it the same treatment and Septimus gave an approving rumble. Pre slowly rolled down the head of Septimus's cock and dripped onto Sam's muscular back. The bead ran slowly down over the fur and the donkey could feel it cool on his rump and drip down onto the floor. Several more beads followed and Sam pulled away from Septimus's balls. He held the two orbs in his hand, rolling them as he slowly licked across the bottom of Septimus's shaft.

The bull mooed softly and placed a hand on the donkey's cheek as he did so. Septimus's cock was placed right between Sam's ears. It was like a cute, perverted runway. Septimus's cock fit snugly right on top Sam's head and throbbed and pulsed. It continually dripped down onto the floor and onto Sam's back.

The beads were a continuous reminder to the donkey jock who he belonged to and what his role was. When Sam made it to the head of Septimus's cock, he licked greedily across the tip. His tongue went across the sensitive glands in a circular motion which got a couple of appreciative throbs from Septimus's cock and a few moos from Septimus.

"That's a good boy," Septimus cooed when Sam brought his soft lips to the tip of the thick cock head and took it into his mouth. He immediately tasted the pre that formed and pooled. He swallowed it down. The taste was salty, but not unenjoyable. Certainly a pleasant flavor that reminded him of his place. Bobbing his head a bit on Septimus's cock, the bull encouraged the behavior by moving the hand that was on Sam's cheek towards the back of the donkey's neck.

Up and down Sam's lips bobbed across the thick head. Even though it was just the tip, it was girthy enough that it gave the sub's jaw a good workout. He could feel his muscles starting to lock up for a moment Septimus knew that he was pushing his pup to his limit. He pulled Sam off his cock and the donkey looked momentarily dejected.

"Awww, don't look so pathetic," Septimus said and placed his large mit right under Sam's chin. He rubbed the soft fur and Sam blinked. "Come up here and give daddy a kiss."

"Yes sir," Sam said, his voice hot and breathy and the donkey stood on shaky legs.

The two shared another soft, intimate, and passionate kiss. Septimus brought his hands towards Sam's, rubbing the palms tenderly as their lips smacked audibly. Sam felt his heart flutter with each movement of their mouths flexing and relaxing. Up and down their lips went and the donkey felt safe and surrounded by Septimus's hard muscle. At this moment, he was his and his alone.

When they eventually pulled away from one another, Septimus was grinning. He let go of one of the donkey's hands, but kept the other safe in his clutches. Septimus's right hand started to slowly move up along Sam's abs and towards his chest. The donkey gasped when the hand found his left nipple and gave it a nice pinch before the fingers slowly started to tease around his mouth.

"Such soft lips....and a wonderful muzzle. Open for daddy..."

Sam did as he was told and even stuck his tongue out. Septimus chuckled and he teasingly circled his index and middle finger around the donkey's mouth. The movement was slow and deliberate as the circling started to get closer to Sam's open muzzle. Each movement had the donkey's heart beating hard in his chest as the fingers moved closer and closer. It was like Septimus had the ultimate say in his arousal. If the bull wanted him to beg, he would. If the bull wanted him to suck, he would.

"Suck..."

Speaking of, the command came right when the two fingers popped right into his mouth. Septimus's silver ring bobbed between his nostrils when he felt a light pressure as Sam did as he was told. He sucked on the fingers obediently, his tongue working across them. He could taste a mixture of chemicals from working on the cars and some dirt. Nothing too acrid however since Septimus kept his hands clean from most debris.

Septimus's other hand let go and started to move up towards the back of Sam's head and led him forward. When Sam started to walk forward, he removed the hand from the back of the donkey's head and lifted up his arm.

"Sniff..."

The bull's pit was right in front of Sam's face and when the donkey hesitated, Septimus stuck his fingers in deeper into Sam's muzzle and threatened to go down his throat. Sam did not gag but merely moaned at the feeling of the threat of his throat being stretched wide by just the fingers alone. He dived forward, sniffing but not able to lick since the bull's index and middle finger were lodged inside of his muzzle. It was like a natural ball gag, keeping him muffled and tame as he could only hump up against Septimus's legs like a horny pup as he tried to control himself around the breeding bull.

Septimus was thrilled. He never tried pit stuff with anyone before but it seemed his musk had a natural effect on jock donks. He stepped forward, pushing his thigh right up against Sam's hard and erect cock. The reaction instantly got a throb and a splatter of pre for his efforts. He barely registered the next needful moan when his fingers started to circle around in Sam's mouth. The amount of stimulation for the jock was getting to be too much.

The donkey started to breath more musk in and the earthy scent was straight from the source. He knew that when he walked away from the mechanic garage at the end of his shift, he would smell like Septimus. Not only would he be marked with the bull's cum but also marked with sweat.

"Step away..."

Sam did as he was told.

"Kneel."

It happened so quickly. Sam was down on his knees and right in front of his bull. Septimus started to stroke his cock in front of him. Moments ago, Sam was getting scolded for not working on a vehicle and now he was a pit slut and had his mouth and tongue open like a needy slut. He wanted it all. He wanted everything that his lover could give him and from the way Septimus was moaning and snorting, he was about to get it.

He could smell the sweat still sticking to his face and taste the fingers that were in his mouth moments ago. Sam could see Septimus's cock pulsing and jumping in front of him as Septimus took a pause to spit a glob of saliva onto his cock. It slickened it up and gave it a nice sheen as he stroked himself off.

The huffs started to come at more intervals and Septimus's eyes stayed locked with Sam's the whole time. It was like a predator watching its prey before it snapped its jaws around its neck. Sam knew that the moment would come and when it did, it would be explosive.

Septimus started to stroke himself faster. His balls wobbled between his legs and slapped his palms as his foreskin went over his cock again and again. Every inch was worked to magnificent perfection and all for Sam to see. The finish came far too quick, but Sam knew this would not be the only climax tonight.

"Fuck, gonna cum, stud pup. You ready for daddy's load?"

"Yes sir."

"Good boy. Open that pretty mouth wide for daddy. Fuck...oh god..."

Septimus's eyes nearly rolled back into his head and he closed them tight. His whole body flexed, the muscles rolling like tides in the ocean. Each one served its purpose and Sam was right in their line of fire. Like a cork being popped off of a glass of champagne, the first shot was the most explosive. A large glob of cum was pushed right out of Septimus's balls and the large bull thrust his hips forward. His tail hiked up and his anus winked as his body worked to cover his boy in his reward.

The glob hit right against Sam's open tongue and the donkey slurped up the offering. A stronger taste than the pre, Sam had no trouble slurping it up and swallowing it. Several more shots soon followed. Some landed in Sam's open mouth while others drenched his body in cum. Septimus's cock was now lubed with cum, the flesh turning slick due to the fluids and a lewd squelching sound started to echo throughout the garage. The shots that did not land on Sam ended up on the ground and spread themselves across it like a perverted show of virility.

The sprays of cum went on and on. Fifteen total shots and each one was thicker than the last until finally it only came down in a dribble to the floor. Septimus was shaking, his body still sending pleasurable signals right down to his toes. He looked down at Sam to see his body covered in cum and smiled, still stroking his painfully hard cock.

"And that's one. Up, boy."

Sam obeyed, wiping cum away from his eyes and moving his hand to let it splatter to the ground to Septimus's amusement. The bull wrapped two arms around the donkey, pulling him close. Sweat, jizz, and fur met in the middle and Septimus kissed Sam's cheek gently.

"I'm not too hard on you, am I?"

"Not at all, sir," Sam said with a blush. "I...like when you take control."

"Good."

Septimus and Sam stood there in the garage quietly for what felt like hours. Just their heartbeats and arousal simmering between them. Sam was still painfully hard, his body not giving up and pumping blood straight down between his legs and Septimus was not any softer. For all the cum and dirty talk, the quiet moment between the two felt genuine and relaxed. Sam placed his head on Septimus's shoulder, enjoying his intimacy for a moment but he knew what he wanted next. The donkey took a glob of cum off of his chest and rubbed his fingers in it.

"Watch me now, stud," Sam said with a teasing grin.

Septimus's eyebrows raised and he gave Sam some space as the donkey's fingers started to trail down his own abs. They moved over the muscle, over his cum covered cock, and down in between his balls. He rubbed the cum on his winking pucker, grinning the whole time before he turned around and gave Septimus a show.

Using his cum covered fingers as lube, he moved his hand around his hips and this time approached his hole from the back in order to get a better angle. He speared them right into hole. There was only a grunt from Sam as the fingers moved deep into his tight and warm hole. He started to wiggle them about, making sure the cum was getting pushed nice and deep and lining his walls.

Septimus watched carefully, his nostrils flaring as he took in the sight. His cock almost looked as if it had gotten bigger from it but that was a mirage; he always was huge and Sam looked on from over his shoulder. He was bent over, his tail flagged as he started to work his cum-covered fingers into his hole.

"You want to breed your boy, bull?"

Sam knew he was provoking the stud but he didn't care. He wanted him. No, he needed him inside of him and spreading him again. He wanted to feel his bull pounding into him and using every muscle he could to make him scream out in ecstasy. The fingers weren't going to cut it.

Septimus said nothing but stepped forward. His hands moved naturally, finding purchase on the side of Sam's hips. It was as if they were made to grab and yank towards his cock. He placed the member in between Sam's thighs and held it there, his nostrils still flared and puffs of warm air were snorted out of his nose.

"You want my tight hole to cum into this time?" Sam asked as Septimus's fingers dug into the muscle of his hips.

Starting to move his thighs, he worked the cock between them. His balls sat right on top of his shaft as he continued to finger himself. He was in heaven as he teased his lover and made sure that he worked every angle of Septimus's cock that he could.

"I bet you were waiting for this for s-AHH!"

In one swift movement, Septimus grabbed Sam's wrist and pulled back to take the donkey's fingers out. The cum soaked fingers dangled in the air for a moment before he placed Sam's arm behind his back. Using his other hand, Septimus grabbed the other wrist and brought Sam's other arm behind his back. He had the donkey right where he wanted him now, his winking hole set up right for his cock. He placed the tip of his cock right against the entrance and rolled his hips, unceremoniously popping in.

The penetration was not easy for Sam to take but he was used to it, quickly relaxing his ring and groaning as the initial pain started to melt into pressure. Septimus was still quiet besides the snorts he was giving out of his nose and his hips rolled forward as he pushed deeper into his lover.

Finally, he spoke.

"Not so cocky now."

Sam was struck mute besides the long moans that came out of his mouth. His prostate was being smashed by Septimus's cock and the breeding bull was only halfway. Sam's mouth was agape when more inches were pushed into him and his legs started to shake and drool began to pool and drip down the side of his mouth. He was reduced down to a moaning, babbling, and begging slut as Septimus's cock broke him once again.

"Fuck..."

"Not yet, but soon," Septimus chuckled with a low rumble to his voice as his hips finally kissed right up against Sam's rump. Balls touched balls and flesh met flesh. Septimus's orbs riveled even the biggest studs at breeding farms and Sam endowment looked small comparatively. Taking one hand off of Sam's pinned arms, Septimus grabbed the donk's left hip with his left hand. He squeezed the muscle and used it to keep Sam up and from falling over.

Sam's prostate was already pushed up against. His legs were still constantly shaking but moreover, he was leaking. Pre dripped down onto the concrete floor of the garage and electrical shocks of pleasure shot down his spine. Septimus noticed this and could feel Sam's hole and muscles closing around his cock before relaxing. He gave Sam a teasing but quick jackhammer thrust.

Breathing reaching a hitch, Sam's cock throbbed once and he came. The shots were thick and full and splattered onto the ground and Septimus just grinned knowingly. Sam shivered as his body pushed out his load, his balls dancing between his legs as more of it shot across the floor.

Sam's muscles were rippling as Septimus started to push in deeper. Sam was a perfect receptacle for his cock. His walls squeezed around Septimus's cock which threatened to milk out everything in his thick member and Septimus did not even realize how close he was to bottoming out until the base of his cock was the only thing popping out in between Sam's thick cheeks and his balls were pressed flush to Sam's thick ass.

Still spasming, Sam's hole clenched and relaxed around Septimus's member. The donkey's head was faced down and he was a hot mess as he tried to find his footing again. His cock was still up and hard, blood engorging the tissue due to the constant push against his prostate. He was in heaven and his body could not help but show how much he was enjoying the stimulation.

"Want me to fuck you, pup?" Septimus said with a smile.

"Yes," Sam said breathily and pushed back against his lover's hips. Septimus, with a grunt, obliged.

Hips started to move and shift. Sam groaned as there was a momentary release of pressure on his backside before the pressure was increased ten-fold. Septimus was using his massive, muscular hips. Gyrating his hips and pushing that cock into Sam's ass again and again, a steady rythm began to build. Balls slapped audibly on balls and Septimus watched his donkey pup lean down to grab his ankles, his tail hiked up. Sam's cock wobbled between his legs and beads of pre streaked across the floor.

"Thank God we aren't fucking on the car, huh?" Septimus chuckled as he pounded into Sam. The pace that he was at wasn't cutting it and his huge body moved fast and hard. Plap. Plap. Plap. Plap. It was like a well-oiled machine. Each hit made Sam squeak out in ecstasy and he blushed at the feminine moans that were coming from his lips. If he wasn't enjoying the furousity of the fucking, then he was certainly enjoying the dominance that was coming from his lover.

The bull felt no shame at pushing into Sam's tight, warm hole. He could feel it contract around his thick shaft as he fucked his boy. He wondered about his son Maximus. He would have loved to watch...

"Mmm, you feel so tight, stud," Septimus groaned out as a squelching sound began to echo throughout the garage. There was so much musk and heat in the small space that each of them got a full inhale of one another as their sex began to increase in pace. Panting, drooling, and pre cum streaked across the floor and began to build up inside of Sam.

"Good thing we aren't fucking on the car, sir," Sam moaned out as his cock throbbed again and his tongue coiled out of his muzzle. Everything felt so good like white hot shots of electricity were shooting down his spine. Septimus grabbed both of the donkey's hips now, thrusting into him at a feverish pace. Their bodies slammed together as each one got lost in the pleasure of the other.

"Good thing. Otherwise, we probably would paint it white. Speaking of, are you ready for your load, stud?"

Sam moaned. "Oh please, daddy. Give me everything!"

Septimus did not say anything more after that. The breeder genes that were inside of him started to each do what they were instinctual evolved to do. Septimus's body started to flex and roll as he propelled his hips forward in hard, slow thrusts. Sam was pushed forward by the force of the bull's hips and his mouth suddenly went agape.

The donkey could feel it filling his guts. Rope after rope of thick, hot cum poured inside of him and went straight up inside. If he was a women, there would be no doubt he would be pregnant and carrying a zygote but instead he could feel that warmth simply fill him to the brim. Septimus barely moaned, his teeth held in a clench as his climax shot through him like a fast-burning fire. His pleasure threatened to consume his mind and he hunched over and twitched as his body produced more cum and shot again and again into his lover.

Fifteen full, thick shots in total. So much that Sam could barely keep it all in. Some dribbled down his balls while other large globs splattered onto the floor in large, thick droplets. Septimus relaxed, his body not flexing for the moment and Sam brought his body up into a full stand. As he did so, the thick cock that was lodged inside of him continued to throb and push against his prostate and the donkey lifted up his arms and put them around the back of his lover's neck.

"Fuck, that was amazing," Sam panted out, his abs lifting and falling as the afterglow began to work its magic.

"As good as the first time?" Septimus asked with a grin as he placed his chin on the donkey's right shoulder and gave Sam's cheek a kiss.

"Oh yes," Sam said. "And I feel like working more now. You gave me an extra burst of energy."

Septimus pulled out of the donkey, a gasp following and then another splatter of cum onto the floor. The bull brought his arm back and then brought it down upon Sam's left butt cheek with enough force that a crack resounded throughout the garage and the donkey's cheek wobbled.

"You'll clean up first, stud. Then you can get back to the car. Use the showers in the back."

"Yes sir," Sam said in a sultry voice but not without a giggle when Septimus gave him a soft kiss on the lips.

______________________________________________________________________

"Fuck yeah, breed that stud," a younger bull said eagerly, his cock enveloped in a fleshlight and his mit clenching the fake ass hard in his hand. The material went up and down his hard and throbbing cock again and again, the tight suction on it barely able to withstand the girth of the bull's thick member.

On the TV was a recording of his own father, Septimus, fucking the brains out of his newest employee. Maximus watched with wide eyes, his own golden nose ring jingling as he took his left nipple in his hand and pinched it enthusiastically. He gave a loud moo, different from his father who was mostly quiet when things got hot and heavy.

Maximus was still in his rugby uniform, the green jersey with yellow trim pulled upward to show his cream colored abs. The lighter brown fur that Maximus had shined in the light from the TV and his thick cock was out and proud along with balls that rivaled his breeding stud of a dad. If only he was in the garage and not stuck watching the camera recording back at home but he was lucky that his dad was so...open about the people he brought home and fucked at work.

Underneath his jersey, his hand worked across his thick pecs until he found his other nipple. He started to tweak and pinch it. His hands eagerly brought the fleshlight up along his cock. The fake toy ended with a free hole at the end where the tip of his engorged dick could pop through. It was cheap but he didn't want to buy anything too expensive. Nothing could really handle his cock over a period of time and with his boyfriend Jules staying late to make the newest designs of gay underwear, he was stuck at home with only the company of the TV and his virtualitized father to sate his urges.

His balls slapped against the lip of the toy and lube rained down onto the floor between his feet. He was cleatless; removing them when he got into the house so he wouldn't track terf around the home.

The door to the living room opened suddenly and Max was greeted by a familiar presence.

"Whew, what a day, son....I-"

Septimus stopped, his eyes falling upon his own flesh and blood playing with his cock and a familiar sound reached his ears. Particularly, the sound of Sam getting his ass blasted.

"Oh, I see you have made yourself comfortable while I was away. Where's your boyfriend?"

"Had to work late. Busy. Kinda like someone else I know," Maximus grinned, his eyes looking over at Septimus who was in his overalls. They were quickly unzipped, a silver cock ring and thick, erect cock flopping out.

"Cocky little fucker, huh?" Septimus chuckled as he walked forward and took a seat on the couch by Maximus who was now beginning to breath harder. Septimus leaned forward, lightly nibbling on his son's left ear which flicked when his blunt teeth found the end and he applied just a bit of pressure.

"Oh fuck..."

"That's it. Fuck your toy. Breed it nice and deep," Septimus grunted into Maximus's ear. "Just like how I bred that donkey slut..."

"Dad..."

"Hmmm?"

The toy started to slicken now. The pre was working it's magic and Max was already close enough. Now with his father egging him on, the taboo was starting to get him there even faster.

"Please...can I breed the toy?"

Septimus chuckled. He would never see his son as submissive. Whenever he fucked his boyfriend, or really anyone that the mouse allowed him to fuck, he was so dominate. So raw and masculine and in control. There was nothing his son couldn't accomplish. However, behind every successful adult, there's a parent who is willing to go the extra mile.

"Yes, son. Give it your load."

"Fuck! Yes sir!"

A torrent of cum. That was the best way to describe it. Maximus was so loud, his roar practically alerting the neighbors to his orgasm. Streaks of cum shot up and over his chest and muscles which Septimus caught in his hands to rub over Maximus's pecs and abs. He could feel the effort his own son put into his body, felt across it and massaged in the most lewd of all fluids into the sinew.

He then brought his hand up to his muzzle and sampled it.

Septimus gave a pleased rumble and started to gather, rubbing it into his own muscles and across his body. If the toy was an ass, it would be overflowing. Probably more than what Septimus did to Sam tenfold. Maximus continued to thrust up into the toy until finally he fell back against the couch. He was far from spent. Septimus knew better than that.

"Thank God I installed those new cameras, huh?" Septimus chuckled and Maximus gave a dopey, relaxed smile back at his father.

"Yes sir," Maximus said with a huff and winced when he pulled the cum covered fleshlight off his cock. Septimus grabbed it nonchalontly and pushed it right onto his dick.

"The cock ring looks new," Maximus said casually when his father started to use the fleshlight. Septimus reached forward and grabbed the remote on the table, rewinding him lining up his cock with the donkey. Maximus smiled contently, his tail thumping against the couch as his father leaned back into the cool leather. The eager son put his head on his father's shoulder, his hand reaching forward and continuing to rub in the cum that Septimus spread on himself earlier and added a little more that was dripping down his own treasure trail.

"That's cause the donk surprised me with it before I left," Septimus said with a smirk. "He loves the fact that my cock looks so big with metal around it."

"Heh, your cock is big enough as is without the ring," Maximus commented. "Can't believe you could even fit it in him."

"Everyone's eager for a bull to ride," Septimus groaned out as the fleshlight started to work it's magic.

"Yes indeed, dad," Maximus commented as he leaned forward and took one of his father's thick nipples into his muzzle and started to suckle on it. The two were practically falling into heat, their bodies getting close as sweat, cum, and musk began to interwine together into one hot concoction. Septimus continued to use the fleshlight and he knew that his son would be around to finish the job. He gave his boy a kiss on the cheek, pulling him close as he watched the recording of his wonderful fuck with his newest employee. Maybe he would introduce Sam to his son? Perhaps another time....
