Umber slowly undressed and placed his clothes in a neat pile on the back of the toilet. His pressed business attire; including a pastel blue shirt, tie, slacks, and cufflinks all set aside as well. The 33 year old stallion was a bit nervous, but also excited. He never imagined when landing his dream job in a prestigious stock market trading company he'd find a community like this. The job was high pressure, fun, and… in a twisted way this type of company party did make a sick sort of sense. 

It was Saturday night in a private office building owned by their company away from the big downtown headquarters. On the outside it was just a normal building, but inside was a whole other story. The privileged members of the team as well as the company's president used it for a way of relieving stress among coworkers. Umber wasn't shy about his sexuality at work, but it wasn't until the junior trader accidentally mentioned being a bottom that half the office perked up. As it turned out, those office parties were usually built around someone drawing the short straw to be the nightly breeding mount. However, Umber was a different breed of stallion that the office rarely could have a bit of fun with. A willing participant. The fresh face and hole.

Umber was smaller than most stallions. His petite figure and curves gave him a slightly more feminine appearance. Standing as tall as he could and looking in the mirror, he took a deep breath then stepped out of the private bathroom into a sea of his already naked coworkers. The chatter died down as all eyes turned towards him. A whistle from a few of the guys were followed by grunts and cheers. 

“Hell yeah, he's fucking hot!” One of them said, from the back of the crowd.

“Check out those curves!”

“Mmmm, you see his cute ass from this angle?”

“Oh I bet he'll call off work Monday! I'm gonna breed that twink, HARD!”

“Now, now boys, don't scare him,” the company president said, stepping forward. His name ironically was Chief. He wrapped an arm around Umber standing beside him.
“Are you still ok with this kid? You can still back out now, it's not a job requirement.”

“Yeah. I want this. It's just…a little awkward, ya know?” Umber looked up at Chief and scanned the crowd of stallions who were all getting hard looking at his smaller body. This caused his own nervous cock to start growing as well. After a few seconds his 12 inch member was flexing in front of everyone. 

“Ok then,” Chief turned from Umber then back to the crowd. “Alright boys, who drew number one?” 

A black horse stepped forward hand raised. It was Umber's direct supervisor, Onyx. The smaller stallion blushed seeing it would be his boss that would be the one to break him in for the others. Obviously this was the first time he was seeing him nude, and it certainly wasn't disappointing. Onyx was muscular and fit. His 15 (or so) inch stallion cock was thick with a predominant flare and balls that just screamed to be milked dry. 
Umber caught himself staring as he was led to the center of the crowd. There, in the room's middle was a large circular bed, covered in a silky red sheet. There were multiple pillows for obvious support. Surrounding the bed all along the room's edges were a series of couches and chairs. Some of his coworkers were already reclining on them and casually giving each other handjobs to stay hard. 

“On your back boy,” Onyx instructed. 

The small dark brown stallion laid back looking up at the towering dark male over him. He gulped, having his legs forced apart, and tail brushed aside. The dark stallion smirked, flexing his shaft up and squeezing some precum over Umber's hole. The cheers and laughter from the crowd seemed to deafen around Umber as his focus became on his boss’ cock. Nodding to show he was ready to submit, he awaited his first breeding.
Onyx snorted and clopped his hooves forward pushing his flare inside with a loud PLOP! Umber moaned delightfully as he felt his body stretching open by the stallion's thick cock.

“Damn, nice and tight! Hold on boy, I'm not holding back,” Onyx grunted, then began pumping. In and out… hard and fast..
He wasn't kidding about his intentions.

PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

Umber laid back and closed his eyes. Every thrust caused him to let out soft moans. He could feel Onyx's cock deep inside him. It felt so good getting used like that. His body was the perfect size to squeeze tightly around the stallion giving them both immense pleasure.

PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

He wasn't sure how long Onyx was inside him before reaching climax. He just enjoyed the sensation of feeling that flare grind back and forth on his prostate. His own small cock slapped against his chest repeatedly spraying precum all over his body. He didn't care about that though he could hear whistles and cheers from his other coworkers as Onyx grunted and neighed. A loud gasp escaped Umber as a rush of warmth filled him up. The black stallion's cum was super thick and there was a lot of it. Even after pulling out Umber felt a few ropes hit his thighs as Onyx stepped away. 

“Ok next up!” He heard Chief call out.

Umber glanced up to see who it was. Though he didn't know the guy's name, he recognized him from one of the other teams. He was a pure white stallion with a dark black cock. He looked longer than Onyx but nowhere near as thick. Umber smiled and laid back with his eyes closed again. The white stallion said nothing as he slipped his full length into Umber's cum soaked tailhole. Gasping again, Umber clenched down around the stallion's cock squeezing him. They both moaned then it began again.

PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

Umber could feel himself cumming from being pumped full once again. His body shivered and his cock throbbed. His hands turned to fists, gripping the sheets while he bit his lower lip. The white stallion held his legs open and still as they both came. Despite the obvious nature of getting used as the office fuck-toy, they still cared enough to make sure he was ok.
The next stallion flipped Umber over, pumping him full on his knees. The 4th held him up, grinding a short thick cock perfectly on his sweet spot. It continued on like that for hours. Each stallion had a preferred position, and Umber let them use his body over and over. It was pure bliss! He never felt so satisfied in his life, getting repeatedly pumped full of cum. By the time about half of the office had finished inside, Umber and the bed were totally soaked. The air was rich with musky stallion cum. It took a moment for him to realize, but suddenly it all stopped. 

“How are you holding up?” Chief asked. Umber sat up to see him holding a few bottles of water. “Here, keep yourself hydrated.” 

“Thanks,” Umber replied, taking the bottle and downing it, then reaching for another. He was drenched in sweat and a mix of cum from himself and dozens of others. Chief sat himself on the bed's edge, rubbing Umber's back.

“I gotta admit I'm super impressed. You're taking the whole team like a champ!” 

“Thank you, sir,”  Umber replied, panting. 

“I think we can afford to bump your salary up a bit if you want to do this more often. Umber's face lit up by the prospect.
“Of course it's not solely determinant on your performance after hours. We still need you to be committed at the office.”

“Of course.”

“Good,” Chief stood up stretched. “Keep things up, the senior traders are up next. They tend to go a little rough. Then I'm always last, but I'll be more sensual.”

“Sounds great!” Umber replied tossing the empty bottles on the floor. Laying back in the wet sheets he closed his eyes and waited.

… …

PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

Chief wasn't kidding about the senior traders. The first new round had two of them inside Umber at once! Luckily their cocks were notably thinner than the rest, but the constant back and forth was wild! In an alternating pattern one would pull back and the other would thrust in  all while Umber was held between them.

PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

Then of course they both came at the same time causing an ocean of cum to spray out of Umber's tailhole from the sides. The next stallion was a draft horse. Easily the biggest cock in the room. It was nearly as thick as Umber's lower leg! If it wasn't for the sheer volume of cum already inside him, there was no way it would have normally popped inside. 
This monster was unbelievably intense. Umber could only fit half of it in, but that was more than enough to turn his moans into screams. This one also was keen on giving Umber a simultaneous hand job, filling him with sensations on both ends. Umber's cock throbbed repeatedly as he felt it being milked dry. Thankfully the draft horse pulled out to cum, and simply enjoyed painting Umber's body with it.

Enduring another solid 2 hours of relentless breeding, it was finally time for the Chief. There was a pause between the others and him, giving Umber a moment to get another drink and look around the room. By this time some of the other guys were getting dressed. A few were licking each other clean, and others making trips to the bathroom to wash up. It was clear there would be a smaller audience with Chief, if one at all. Great care was being taken to clean the floors as well. Everyone did their part to wash off all the excess cum around the room and on each other. 

“Well looks like you had a good time,” Chief said, walking over to Umber. Umber nodded and Chief sat on the bedside.
This was the first real good look Umber got at him. Chief was had deep amber fur like himself. He was gently stroking himself back to full mast, as it appeared he let himself fall flaccid while the other guys enjoyed themselves. His cock was a lot closer in size to Umber's than the others too. Though still bigger, it wasn't the monster some of the others had. The way he looked at Umber was different too. It was less like a plaything and more equal. 

“Yeah, this was intense…but good. 

“Glad to hear it. I don't normally have them all leave, but I wanted to do something special for our newbie.” 

Umber blushed and smiled. “Like what?”

“Just give them a few minutes and you'll see.”

One by one the other guys slowly trickled out. All waving with thanks to Chief and Umber for a good time with promises for a normal Monday morning. Then it was down to just the two of them. With the door slamming shut, Chief crawled onto the bed and between Umber's legs. Scooping his arms up underneath him, Chief admired Umber's half hard cock. 
“This really suits you, despite your size. You should be proud of it.”

Umber blushed again, “Th…thanks.” 

“After all you did for the guys tonight I think you deserve a little reward.”

“What do you me….OH!” He gasped as Chief closed his lips around Umber's cock. “Oh, yeah!” He moaned, watching, and stiffening back up.

Chief slurped up and down, letting Umber's musky cock slide down his throat. The flavor of dozens of his employees mixed with Umber's natural scent caused his cock to throb. He gently sucked all the cum off, then pulled back to clean Umber's body. Slowly and with detailed intention, Chief licked all over Umber. He swirled his tongue scooping up every drop hidden in the crevices. As he moved closer to Umber's head, he lifted the smaller stallion into his arms. Tongue tracing up his neck, the a brief kiss on the lips.

“You sure taste good,” Chief said seductively. Setting Umber down on the floor off the bed, Chief crawled on his hands and knees wiggling his butt in the air. “Come get it, Umber. You can top me as a reward.” 

Umber's jaw just about hit the floor. Chief was going to bottom for him! He certainly didn't need to be told twice. Umber stepped forward rubbing his cock between the stallion's cheeks. He smacked it across Chief's tailhole a few times, then pressed his tip on it. Looking back over his shoulder, Chief gave him an approving nod, then faced forward letting Umber mount him. 
“AH, that's it!” Chief moaned, feeling Umber's cock slide into his ass. “Good boy!”

Umber moaned as he began thrusting to his heart's content. He was pretty weak at the knees from being pumped full of everyone's cum, but he managed to hold onto Chief to stay upright. After being on the receiving end for hours, it felt good to be giving it to such a willing participant. 

PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

Both horses moaned, enjoying themselves together. Each thrust bringing them closer to a shared climax. Umber was amazed how in sync he was with Chief. Their bodies reacted back and forth with a throb and squeeze then a squeeze and throb. Despite having been milked over and over, Umber still could feel precum oozing from his cock.

PLAP PLAP PLAP PLAP PLAP PLAP PLAP 

“Sir, I'm close,” Umber moaned.

“Me, t…too. Do it inside, boy!” 

“UNGHAAA!” Umber shouted, feeling one final orgasm rock his system. His flare expanded and his cock throbbed, but after a long night he had been milked basically dry. Only a few dribbles escaped his cock, but that was more than enough for Chief to feel it. The way Umber's cock pulsed sent him over the edge as well. Chief's load was huge too! After edging all night, he exploded adding his mark to the already soaked sheets. Each squirt caused him to clench around Umber as he moaned and whinnied. 

SHLOOOP 

Umber pulled out and staggered trying to remain standing. Chief relaxed himself and spun around, holding Umber's hands to support him. Smiling up at his junior employee he smiled. 
“Good job, boy. You made me proud tonight. That raise will be in your next paycheck.”

“Thank you, Sir,” Umber nodded, then wobbled his way to the bathroom.

… …

Umber took his time cleaning up the residual cum that Chief hadn't licked off of him. Mostly it was on his back which wouldn't come off until he showered at home anyway. Pulling his clothes back on he tucked his nearly flaccid cock back into its cloth prison. Adjusting his belt and buttoning up his pressed shirt, he smiled knowing everything that just happened. He was back to looking like a business professional. 

Stepping out of the bathroom, he saw Chief was dressed back in his suit as well and changing the bedsheets. Shoving the cum-soaked ones into a trash bag, he tied it shut then swung it over his shoulder. 
“That about does it. Thanks for being such a team player, Umber. The guys really have taken a liking to you now.”

“Yeah I bet,” Umber scratched his head and blushed. “So uh? I guess I'll be on my way.”

Chief nodded and extended his hand, firmly shaking Umber's. “Of course, see ya Monday.” 

Turning and heading for the door, Umber could feel a bit of cum running down the back of his leg. It was gonna be a long drive home.
