Finally, out of the blinding light from the cargo doors, in came a large gypsy vanner horse, with a naked otter woman riding on its back.  The large feral stallion trotted into the lab proudly, its head raised high as it slowed down and turned around full circle in front of the observation room, giving an excellent view of this fine animal.  His fur was all black, but his mane, tail, and hoof featherings were all an ivory white.  His muscles rippled and tensed under his short fur as he whinnied and reared up, standing on his back legs briefly while the otter woman yelled out a quick "YEEH-HAW!" with a giggle.  Then the horse came down hard on his front legs, shaking the entire lab with his powerful frame and stature.

The otter winked at the guys sitting in the observation room, then she pulled her leg up, making sure to flash her underside at the guys as she slowly slipped off and dismounted the horse.  She pulled the reigns up and off the horse's muzzle, giving him some quick pets and a kiss on the nose.  The horse moved his head up and over, nuzzling the otter's ear a bit before the otter slipped away and waved over to the room again.  "Hey boys, I need someone to help me handle out here.  Any volunteers?"

Everybody in the room jumped out of their seats before Rhem called out, "Hold it!  Stay in your seats.  All of you need to continue observing.  [i]I got this[/i]", with a wicked grin.  He ignored the mumbled groans of his colleagues as he then leaned forward and stood up out of his chair, and sauntering over to the door with a big grin on his face.

[i]It's good to be the king[/i]

The chubby panda entered the lab and closed the door tightly behind him.  He looked over at the lady otter, who just looked at him and shook her head.  Rhem raised an eyebrow and walked over to her and the horse, "Hello there."

The otter shook her head again, "Unacceptable"

Rhem looked around, then back at her, "What do you mean?"

She gave him a playful glare, "I'm naked, the horse is naked, you have to be naked too."

Rhem looked down at his body.  He had forsaken his pants back in the lab, but his lab coat and shirt were still on.  So he nodded to the otter and walked over to one of the small consoles that flanked the table in the center of the lab.  He unbuttoned his coat and tossed it over the console, then his long-sleeve shirt, and finally his undershirt.  As he stood there, now completely naked in front of his colleagues, he couldn't help but bend over in the direction of the observation room and wiggle his rear teasingly at them.  He ran his paws over his slightly rounded figure, making sure his fingers graced the curves of his belly, his thighs, and his ass.  His cock started to harden again in the cool morning air that was blowing through the lab now.  His balls hung heavy between his legs and bounced playfully off of his thighs as he wiggled around.

His vain little show was interrupted by the otter subtly clearing her throat.  Rhem looked over at her and stood up straight, walking back over to her as casually as he could with both of them being naked.  She was lightly brushing the horse and seemed to really not take any notice of Rhem's half-hard cock.  That was okay.  He liked it when they played hard to get.

She turned towards him looked him right in the eye with a big smile and extended her hand,"It's nice to meet you Mr. Rhem.  My name's Lisa."  Her voice was vibrant yet easy on the ears.

Rhem smiled and shook her hand, "Likewise.  However, my dear, we've already seen each other naked.  I think we can dispense with the formalities of -Mr.-"

Lisa chuckled and nodded.  "Shall we introduce the volunteer to his partner today?"

Rhem nodded back to her, "Absolutely".

Lisa ran her paw under the horse's chin, rubbing it affectionately.  As she walked towards Draco Rex on the table, the horse followed her over without any need of a lead.  The little dragon looked over at them with a bit of fright in his eyes as they approached the table.

"Mr. Rex", she started, "Meet Bruce.  He's a..."

The horse nosed past Lisa and started to sniff at the little green dragon.  The horse sniffed at the dragon's belly, then up to his snout.  He gave Rex a little lick on the nose, then started nuzzling him.

Lisa had a big smile, "There we go!  Bruce is one of our resident stallions here, and he's very friendly.  He enjoys playing with the big bouncy balls we have scattered in the fields, laying out and absorbing sunshine, and sometimes runs out to the beach and plays around in the surf."

Rhem patted the side of the big horse.  "Bruce, meet Draco Rex.  He enjoys getting sodomized six ways from Thursday"

Lisa gave Rhem a playful punch in the shoulder, which made him break out into giggles, "Oh, come on, I thought it was funny", he said.  Lisa shook her finger at him and went back to petting Bruce's neck and mane.

"Anyway, Lisa, are we ready to get started?  The volunteer has already been stretched out."

Lisa nodded, "Yeah, we should be ready to go then."  Then she led the horse over to the foot of the table, turning it around and making it face Rex.  Rhem walked up alongside Bruce and patted his side, giving him some gentle rubs.  Lisa reached down under the table and pulled out a little spray bottle, giving Rex a few quick sprays of some oddly smelling substance across his tailhole.

"This..", she explained to Rex, "is some hormone extract from mares in heat.  Since horses primarily react to scent, we just made you smell like a slutty mare just begging to be bred!"

Lisa put the bottle back under the table and stepped back from the horse, gesturing to Rhem to do the same.  He took several steps back, then he turned and looked over his shoulder, giving the guys in the room a toothy grin.  Then he turned back and watched the horse.

As everyone watched, the horse stood there, sniffing at Rex's ass where Lisa sprayed.  Then the horse took a step back and snorted loudly.  He turned around and started walking out towards the large bay doors.  He lifted his head and sniffed the air aggressively.  Then he just idly stood there, sometimes clomping around to another part of the lab to sniff at some of the equipment.

Rhem looked at Lisa with a puzzled look on his face, "Okay, what's wrong here?"

Lisa shrugged, "I don't know.  He may be a bit confused because we haven't used him for breeding before."

"I thought that we were going to use an experienced stallion for this?"

Lisa sighed, "The stallion we were going to use was mistakenly lent out this morning for someone to ride.  That was the holdup earlier, when I was trying to find our horse.  When I found that a paperwork mix-up had our staff give out the wrong horse, I brought in this guy."

Rhem walked up to the side of the large Gypsy Vanner stallion, rubbing the base of his neck.  Rhem smirked to himself as he thought about how his black and white fur almost perfectly matched the tones of the horse's fur and mane.  "Well, he is a very beautiful horse.  Is there anything we can do?"  The horse's ear perked back, and the horse leaned around to look at Rhem.  He gave Rhem a quick lick on his arm, then he leaned to the side, pressing into Rhem's paw as he rubbed the stallion's neck.

Lisa walked around to the front of the horse, patting his nose gently and giving him a quick kiss between his eyes.  "There, that's a good boy, right?", she said.  The horse seemed to nod and pressed his muzzle lightly up against Lisa, and she started to rub and caress his cheeks and forehead.  "Well..", she said to Rhem, "we could try physically stimulating him.  Scent works most of the time, but some horses are different.  Horses are just like us, they can be turned on in different ways.  The majority are turned on by the main thing, but sometimes you have to venture outside the norm to get a rise out of 'em."

With that, she put her paw just under the horse's chin, signaling to the horse that she wanted him to follow her.  He perked his ears up at attention and followed her as she led him back to the foot of the table where Draco Rex was strapped down.  Lisa gave the stallion another "Good boy", and kept petting his snout.  She sat on the foot of the table and slid her big otter tail up and along Rex's body.  The tip of her tail ended by his belly, so she looked back at him with a smile and rubbed his side gently with her tailtip.  Then she looked back over at Rhem, "Okay, since horses get distracted easily, I'll keep Bruce's attention here with some loving pets.  You get under him and see if you can get him started.  Whatever you do, be very gentle.  A horse's skin is very sensitive.  If he moves himself away from you, stop immediately.  And watch out for his legs and other body movements.  He weighs in at more than 500 kilograms, so if he starts to shuffle and move his legs, watch out.  If he steps on your foot, he's likely to break it."

Rhem nodded and approached the horse.  He looked over at Lisa and started, "Hey, have you ever...?"

She cut him off before he could finish.  "Not with this one.  If I did, I'd know what to do now."

Rhem grinned and turned his attention back to the stallion.  He ran his paws along the side of the horse, amazed at how toned and powerful the muscles were.  Even the horse's belly was taught.  As Rhem lightly touched over the horse's fur, the horse's skin twitched and the horse snorted what sounded like a chuckle.  Rhem called out with a playful voice, "Oh, do we have a ticklish horsie?"

Rhem started lightly dancing his fingertips across the tip of Bruce's fur, making the horse twitch and snort.  The panda couldn't help but think that this was absolutely hilarious.  He started laughing and tickling the side of the horse, while the horse started fidgeting around and whinnying.

Lisa grunted, "C'mon Rhem, get serious!"

Rhem called back, "Hey, for all we know, this is what will do it for him, right?"

But before he could do anything else, the horse pulled back from Lisa and spun around, using his shoulder to knock Rhem clumsily to the ground.  The horse knelt down and used his weight to pin the panda to the ground.  He then started licking Rhem's face relentlessly.  Rhem busted out laughing, though a bit strained with the heavy horse keeping him pinned against the ground.  As the horse gave him one big, wet lick after another, Rhem said, "Lisa, this guy is absolutely ADORABLE!  Can I take him home with me?"

Lisa got off the table and went over to the horse, who was still busy licking and nuzzling all over Rhem's face.  She patted Bruce under his chin and got his attention, leading him off the panda and closer to the bay doors.  "That's really cute Rhem, and I'm glad you two really like each other, but this isn't what you're here for.  Maybe we can just continue this later today when the other stallion gets back in?"

Rhem picked himself up off the floor and stretched out.  "Yeah, perhaps that is the best solution.  Such a shame, though, all this work to get the volunteer ready was a waste.  We'll have to put him through it all over again in a few hours."

Rex's head lifted off the table as he looked over at Rhem with wide-open eyes and let out a exasperated "Whrrppph?!!"

Rhem looked back at Rex and waved him off, "Oh, don't worry, you'll be fine".

Suddenly one of the techs called into the lab from the observation room, "Hey guys, we just got a call in from the stables.  The stallion is back, but he broke free from the handlers.  He darted up the trail that leads here."

Lisa turned a bit pale and looked over at Rhem, "You need to shut those doors [i]now[/i].  Stallions are very competitive, and if..."

Before she could finish, they could hear that noise echoing in from around the building.

[i]clomp clomp clomp, clomp clomp clomp, clomp clomp clomp...[/i]

Within moments, the other stallion raced in through the bay doors, making a quick loop around the interior of the lab and coming to a screeching halt just a few meters from the Gypsy Vanner.  This stallion, however, was a brown and white draft horse, and a good bit larger than the Gypsy Vanner stallion.  Both stallions started eying each other up, using their front feet to bump the ground a few times.  The draft horse reared his head up a bit and snorted loudly at the Gypsy.

Lisa called out tensely, "Rhem, that is [i]Tornado[/i], the stallion that was supposed to be here in the first place.  Stallions tend to be very competitive, so I need you to get back into the observation room where it's safe.  I will try to handle this.  Keep an eye on what is going on, and have a tranquilizer rifle ready."

Rhem opened his mouth but wasn't able to mutter even a syllable before Lisa yelled out, "[i]NOW!!![/i]"

The panda quickly walked over to the door to the observation room and slipped inside.  Lisa walked very slowly over the Gypsy Vanner, who was closer to the door.  She brought her paw up under his chin and patted it, whispering, "C'mon boy, time to go.  Follow me"

But as Lisa tried to walk away, Bruce didn't budge.  His eyes were still fixed on Tornado.  Lisa grumbled tensely and reached for his reigns, but he shook his head and took a step towards the draft horse, and stopped there.  Lisa's ears pinned back against her head, her tail stiff as she watched this situation quickly spiral out of control.  She called out, "Guys, I think right now you need to tranq the Gypsy.  He's smaller, the sedative will work quicker on him.  And you best shoot him now before these two come to blows.  This is going to get really serious really fast if you don't get on top of it."

She slipped back against the wall of the lab and shuffled away slowly, although neither horse seemed to notice.  She slinked her way to the bay doors, moving out of the lab completely but watching from the doorway.  The otter looked over at the observation room as the guys in there seemed to be arguing with each other.  She grunted and yelled, "Guys?  NOW!"

Rhem went over to a console and hit the intercom button, "Um, someone forgot to bring the rifle.  BUT!  We have the tranq dart, so maybe you could just run up and poke one of the horses with it?"

Lisa facepalmed hard and shook her head, "I work...with idiots."

The Gypsy Vanner took another step towards the draft horse.  They were now almost touching.

"Bruce, get back here!", Lisa shouted.

Both horses leaned forward just a bit and sniffed at each other.  Their ears perked, and the draft horse snorted and grunted.  Then Bruce slowly moved forward, moving alongside Tornado.  He craned his head down and to the side a bit, nosing under the draft horse's belly.  The draft horse kept his head high, ears still perked and alert.  But the situation was still tense in the lab.

Bruce nosed over Tornado's belly, sniffing around idly.  Then he moved forward a bit more and buried his nose between the legs of the draft horse.  He sniffed at the draft's sheath a few times before he opened his mouth up and gave it a big lick.  The draft horse shuddered a bit and whinnied again, but otherwise kept still.  Bruce licked over the tip of the other stallion's cock.  Then he did it again.  As the draft horse's cock grew out of his sheath, the Gypsy kept licking at the base of his cock, nosing it and breathing hotly over it.

Lisa, Rhem, and everyone else just stood in a stunned silence, watching this interesting turn of events.

Tornado's cock expanded quickly and started to harden.  Each time the Gypsy Vanner stallion licked the base of his shaft, his cock would tense up and slap against his belly.  Bruce moved his muzzle back a bit more and started licking and nuzzling the draft horse's balls.  That big, wide, wet tongue caressed the stallion's balls with the utmost care, slithering over those smooth orbs, making the draft stallion's cock tense and squirt precum all over the lab floor.

Lisa's jaw was hanging open, amazed at what she was seeing.  But she also couldn't help but be a little turned on by the sight of one stallion licking another stallion's balls.  She leaned up against the doorway to the lab and brought her paws down to her crotch.  Her pussy was already moist and warm.  So she slipped a few fingers across her vaginal lips and moaned at the teasing sensation.  She kept her eyes locked on the two stallions as she then took two fingers and slipped them into her pussy, wiggling them around just inside her as she blushed and tensed up, automatically squeezing her legs together around her paw.  She forced herself to relax and spread her legs once more, and she spread them wide as she pushed her fingers deeper into herself, squealing with passion as her fingers plunged in deep.

Rhem, still in the observation room, was watching this all very closely.  His cock was hard and throbbing, his balls aching for release.  But, he kept his paws at his sides.  Release would come later.

Christopher walked up next to Rhem, and they both watched the stallions.  Bruce was still licking and nuzzling the cock of the draft horse, licking up and down the length like a lollipop.  Chris looked at Bruce then back at Rhem with a smirk on his face.  Rhem rolled his eyes and grunted.  He knew he didn't want to hear whatever smartass comment Chris had, but if he knew it was coming anyway.

"So, Rhem...", Chris started.  "Bruce is really licking that stallion's cock, isn't he?"

Rhem nodded, but said nothing.

"You know, Bruce was licking your face just like that too, Rhem.  Does that mean you're a dick-head?"

The guys in the observation room started chuckling.  Rhem shook his head and sighed.  "Chris, I'm going to remember that next time you're up for a raise"

Chris was still grinning.  He was standing next to Rhem, leaning ever so lightly against him.  "Well, that's fine. Next time I'm up for a pay review, are you going to remember my balls too?"

Rhem looked at Chris, then back at the lab.  Rhem's paw moved over and gently cupped Chris's balls, "You're forgiven".

Chris chuckled and parted his legs a bit as Rhem's paw caressed his balls and sheath.  He moaned and humped lightly at Rhem's paw while he watched the stallions.

Bruce moved his muzzle down along the length of Tornado's cock, finally licking at the tip and catching some precum on his tongue.  He kept licking the draft horse's tip as it flexed and shot precum all over the Gypsy Vanner's muzzle.  Finally, the draft horse started to move forward, past the Gypsy Vanner.  He turned around and got behind the other stallion, bumping his nose up in between Bruce's legs.  Bruce spread his legs out a bit and flicked his tail off to the side.  As Tornado sniffed along Bruce's underside, Bruce spread his legs a bit more and braced himself.  The draft horse pushed his nose forward between the Gypsy Vanner's legs until his nose reached Bruce's balls.  He parted his lips and gave Bruce's balls a quick lick, which made Bruce's cock start to grow and expand out of his sheath.  The draft horse kept licking Bruce's sac, dragging his smooth tongue along the smooth surface of Bruce's heavy balls.  Tornado slipped his tongue along the groove between Bruce's balls then pressed his lips against the Gypsy Vanner's ballsac in what almost seemed like a kiss.  Bruce's cock grew fully out of its sheath and shot pre across the floor every time the other stallion licked over his balls.

Finally the draft horse pulled his head back and jumped up, his chest landing hard on Bruce's rump as his front feet wriggled around and locked in around Bruce's hips.  The draft horse's cock throbbed and stood hard at attention, hanging in the air as the stallion lined up on the asshole of the other stallion.  Tornado's cock shot a quick shot of pre into Bruce's crack, making Bruce flick his tail to the side and exposed his tailhole.  The draft horse inched forward, his cock rubbing up inside Bruce's crack, shooting more pre until it was dripping down Bruce's crack and onto the floor.

Tornado's cocktip finally found Bruce's tailhole, rubbing across it and shooting pre all over it.  Bruce snorted as he felt the stallion's cock against his ass and he pressed himself back, pushing his tailhole against the bigger stallion's cock.  Tornado bucked his hips and pushed his cocktip firmer against the smaller stallion's wet, slick tailhole, stretching it out until it finally yielded to the larger stallion's cock.  The large draft horse bucked his hips again, pushing the first few inches of his thick, veiny cock into the submissive stallion's ass.

Bruce whinnied and pushed back again, perking his ass up as Tornado bucked his hips and crammed half of his length into the smaller stallion.  The draft horse nipped at the Vanner's mane and finally caught a good chunk of it in his mouth, biting down and scruffing the smaller horse.  Bruce's ears pinned back flat and he lowered his head submissively as he let the larger stallion dominate him.  Tornado yanked back on Bruce's scruff, making Bruce's cock jump and slap against his belly, firing off another shot of pre that splashed against his chin as his head hung low.  Tornado squeezed his front legs around Bruce's waist as tight as he could, locking the submissive stallion in place as he bucked his hips and drove the rest of his cock deep into the smaller horse.

As Tornado's cock pushed into his ass, Bruce perked his ass up and back, pressing deeper into the thrusts from the larger stallion.  Tornado pulled back and rammed his cock deep into Bruce's ass, and again Bruce pressed his ass back and up, welcoming the larger stallion's cock into him.  Bruce squeezed his ass tightly around Tornado's cock, making Tornado thrust harder and bite aggressively on Bruce's scruff.  Bruce lowered his head more until his chin pressed against the ground, with the larger stallion's frame pressing down heavily upon his body.  He kept his ass perked up for the dominating stallion, and each deep thrust of Tornado's cock into his ass made his cock jump and shoot more pre across his chin and neck.

Bruce snorted and whinnied as Tornado's cock thrusted deep into his ass again.  Tornado pulled his cock back and rammed it deep into Bruce's ass with unbridled fury as he started to work up a quickened pace.  The stallion's nostrils flared open as he started to breathe hard, his powerful muscles glistening with sweat as he brought the full might of his body behind each powerful thrust.  Bruce closed his eyes and braced himself as best he could as he let the larger stallion's cock drive deep into his ass over and over again.

Bruce's ass finally stretched out enough that each time Tornado thrusted, his cock slid in Bruce's tailhole up to the balls.  Each time Tornado slammed his cock into Bruce's ass, Tornado's large, heavy balls pressed up against Bruce's ass.  Bruce quivered at the feeling of the large stallion's balls slapping against his ass, causing his muscles to buckle under the strain of the dominating stallion's power.  Bruce's front legs gave out and he landed hard on his chest, but he managed to keep his back legs upright and locked, with the larger stallion's cock still buried deep in his ass.  Tornado stumbled a bit as his front end went down with Bruce, but he quickly got his front feet under him again and pushed himself up.  Then he brought his front legs over and down on Bruce's shoulders, pinning him down against the ground.

Bruce's ears stayed pinned back submissively as he whinnied and wiggled his rear, the stallion's cock still buried deep inside.  Tornado locked his front legs down on Bruce's shoulders to make sure he didn't move again, then he leaned down and scruffed Bruce again, making Bruce's cock tense and shoot pre across his chest.  With the submissive stallion pinned down underneath him, Tornado resumed taking his ass.

The larger stallion bucked his hips and crammed his cock balls-deep into Bruce's ass.  Bruce's ass squeezed around Tornado's thick cock every time Tornado's balls bounced against Bruce's rear.  Tornado slammed his thick cock into Bruce's welcoming ass over and over again, and Bruce simply spread his legs out a bit wider and accepted the dominating stallion's cock as it rammed deeply into him.  The more Bruce submitted to him, the faster Tornado fucked him.  Bruce's body rocked every time Tornado's cock drove deep into him.  He bucked his hips and drove his haunches forward, forcing his cock in and out of the smaller stallion's tailhole again and again without mercy.  Finally Tornado grunted and squealed out loud, releasing Bruce's scruff and holding his head up high as he slammed his cock deeply into the smaller stallion and climaxed, his cock pulsing and tensing as he shot his cum deep into the smaller stallion's ass.  He kept his front legs on Bruce's shoulders, keeping his front end pinned to the ground while Bruce's back end stayed up and taking Tornado's load.  Tornado's cock jumped and tensed and pulsed as more and more of his cum filled the submissive stallion, his seed flowing down deep into the guts of the other horse.

Tornado slowly bucked his hips a few more times, his cock visibly throbbing as more of his cum shot out of his thick cock and into Bruce.  As Tornado worked himself back and forth, his cock eventually slipped out of Bruce's tailhole, fully flared and still shooting cum.  Thick ropes of cum splashed across Bruce's abused tailhole and down the crack of his muscular ass.  Tornado's cock kept throbbing and shooting his seed across Bruce's ass until his white cum was dribbling down Bruce's crack, and down his legs.  Finally, his cock softened up and started to shrink back down again.  He stepped off Bruce to the side and started to catch his breath as Bruce finally relaxed his back legs and eased himself into laying fully on the ground.

Tornado took a step forward, putting himself just alongside Bruce.  He leaned over and bumped his nose against Bruce's head, and Bruce turned to look at him.  Tornado whinnied loudly at Bruce and bumped him lightly, this time on the neck.  Bruce snorted softly and rolled over onto his side, his belly facing the dominant stallion.  Tornado put one hoof up on Bruce's shoulder and leaned forward, bumping his nose along Bruce's snout.  Bruce leaned down a tad and started licking Tornado's nose.  Tornado's ears perked and he snorted happily as Bruce started to lick and nuzzle all over his nose and snout.

Then, Tornado opened his mouth and stuck his tongue out, catching Bruce's tongue by surprise.  Bruce's head pulled back in surprise, but Tornado pressed his hoof down on Bruce's shoulder and pushed his head forward, locking his lips against Bruce's and forcing his tongue into Bruce's mouth.  Bruce could do nothing but sit still and keep his mouth open as the larger stallion kept him pinned down, using his tongue to explore around inside his mouth.  Tornado's tongue slathered around Bruce's mouth, snaking around Bruce's own tongue and licking around inside.  Tornado's large, thick, brown, veiny cock started to grow once more as he locked the submissive stallion in the deep kiss.

Tornado then pulled back from the kiss and pulled his hoof back off of Bruce.  But then he leaned down and bumped his head against Bruce's chest.  Bruce looked down at him, and Tornado again bumped his head against Bruce's chest, this time keeping pressure on just under Bruce's right hoof.  Bruce seemed to get the hint, as he rolled over onto his back and kept his hooves tucked in close to his body.

Tornado's cock jumped and leaked some pre, obviously ready for another go.  The large draft stallion moved to the side and carefully climbed over the smaller Gypsy Vanner horse.  The two stallions were now belly-to-belly, although Tornado did slide back a bit so he wasn't perfectly centered over the smaller stud.  Bruce's own cock, still hard from the fucking he got a few minutes ago, laid flat along his lower belly, while Tornado's cock was still hanging down low.  Tornado leaned down again and locked lips with Bruce again, forcing his tongue into the Gypsy Vanner's mouth and licking around inside there.  His cock started to harden up once more, dragging his cocktip along as his cock became rigid again.  His tip slid up along Bruce's balls, dribbling a little bit of pre onto them.  Then it slid up along the length of Bruce's cock, rubbing firmly against it until it came to a rest about halfway up the length of Bruce's shaft.

Tornado kept Bruce locked in that tongue kiss for several more minutes as he stood over him, forcing his tongue around inside the smaller horse's mouth.  Then he pulled back out of the kiss, nibbled a bit on Bruce's neck, and locked his legs around Bruce's body.  He took a small step back, letting his cocktip drag across the underside of Bruce's cock.  Bruce's cock jumped at the soft touch, shooting some pre onto his own belly.  Tornado's cock dribbled a bit of pre onto Bruce's cock, and then he shifted forward, pressing his cocktip down against Bruce's cock and sliding up along the shaft, smearing his precum along the full length of Bruce's thick studhood.

Bruce whinnied softly and leaned up, licking along Tornado's chin.  Tornado snorted and bent down a bit, pressing his full body weight down on the smaller stallion.  Tornado bucked his hips and slid his cock against Bruce's again, both stallions' cocks twitching and shooting pre as their sensitive flesh rubbed up against each other's cocks.  Tornado pressed his groin firmly against the other stud's groin as he bucked and pressed his cock firmly against Bruce's.  As Tornado's cock rubbed pre across the smaller stud's cock and his own belly, each thrust started to get slicker and easier.  Tornado's cock glided firmly back and forth across the length of Bruce's cock, each stallion whinny-ing and snorting as their studhoods rubbed against each other.

Tornado's coconut-sized balls swung forward and gently slapped against Bruce's balls each time Tornado thrusted forward, making the smaller stallion fidget and press his groin firmer against the more dominating stallion.  Tornado started to pick up the pace, gradually thrusting and grinding their cocks together with more speed.  Both of their thick horse cocks were throbbing and twitching as their long, thick cocks rubbed and frotted and slid together.  Tornado's flare started to expand and he started thrusting much faster while pressing his belly down against Bruce's belly.  With their cocks sandwiched between their bellies, Tornado continued thrusting away against Bruce's thick horse dick until Tornado bucked hard and let out a loud snort, his entire cock pulsing as a few jets of his cum shot out from his cocktip and splattered across Bruce's muzzle.

The first steam of stallion cum splashed the bottom of Bruce's muzzle, making him look down at the source...just in time for the second stream to hit him square in the nose and douse his mouth, nose, and cheeks with the rival stallion's cum.  Then he opened up his muzzle and the third and forth shots of cum landed right in his mouth, across his tongue, and dribbled down his lips.  He accepted the rival stallion's cum in his mouth as more cum fired out of the larger stallion's cock, some of it missing Bruce's mouth and landing on his neck and muzzle instead.  As more cum filled Bruce's muzzle, he started swallowing it and sticking his tongue out to catch more.  After a good ten more squirts (and three more swallows), the large draft stallion took a few steps back, his cock twitching and shooting his cum all over Bruce's shaft, groin, and balls.  Tornado stood proud, his head held high as his cock continued to twitch and cum all over the smaller stallion's crotch.  Shot after thick shot of stallion cum covered Bruce's balls and shaft until it started dribbling down along his crotch, down his ass, and dripped onto the floor.  Bruce bent his knees a bit and dragged his cocktip across Bruce's cum-covered balls as another thick shot of his cum coated Bruce's large ballsac.  Bruce's balls twitched, and his shaft shot out a few shots of precum as he felt Tornado's cocktip rubbing up against his balls and still cumming all over them.

Finally Tornado's cock softened up and started retracting again.  He took a few steps back away from Bruce and reared up on his back legs, giving off a loud whinney and shaking his head around.  As he landed hard on the floor, Rhem hit the intercom button, "Tornado, even if you are just a simple horse I wanted to take a moment and tell you that, damn, [i]you are the man![/i]".

Tornado snorted again and walked up to the window between the lab and the observatory room.  He reared up and moved forward, landing his hoofs heavily upon the plexiglass.  He pushed his hips forward and smeared his softening cocktip across the window and shook his hips seductively before pulling back and landing on the ground.  He slowly walked over to Lisa, whom was still looking a bit in shock, and started lightly nuzzling her.

She grunted, "You bastard, don't play nice with me.  You just cheated on me with another stallion.  I'm not talking to you for the rest of the week".  She put her paw under Tornado's chin, and he complied with following her.  She slowly and carefully led him out of the lab through the bay doors and down the path to the stables.

Rhem, Chris, and everyone else in the observatory room were still in an awkward silence.  Rhem looked over at Chris, and Chris just shrugged.  Rhem then looked over to the rest of the observing scientists and technicians, whom looked at each other and shook their heads.

Finally Rhem spoke up, "Someone, PLEASE, tell me we got that on video."

Everyone in the room burst out laughing.  Chris buried his head into his paw, laughing but trying to make it look like he disapproved of the comment.  Rhem just grinned to himself and walked over to the door to the lab.  "Laugh all you want guys, but remember we still have a job to do here.  Get Lisa back here as soon as she returns Tornado to the stables.  I'm going to check on our volunteers."

Rhem slipped his musclechub body through the doorway and closed it behind him.  He walked over to Bruce, who was still laying on his back on the floor, although he was busy licking his own muzzle as best he could to get the jizz off.  Rhem knelt down and shook his head, "You poor thing.  They named you Bruce, so I'm not surprised you ended up being plowed by another guy.  I mean, really, with a name like "Bruce", your sexuality didn't stand a chance of being straight.  The good news is that I have a nice, tight little dragon here for you who is very much male.  And I hope you're up for using him like a sexual playground even half as much as Tornado just used you."

Rhem reached out and pet Bruce's muzzle, ending up with a bit of Tornado's cum on his paw.  He couldn't help but pull some of it up to his muzzle to lick it off.  He opened his mouth wide and slid his tongue up and down each of his fingers like it were a lollipop, coating his tongue in Tornado's cum.  It was very thick, a bit gooey even, warm, and salty.  Yet in an erotic way it was divine, like the aphrodisiac of the gods.  He licked a big glob of it off the back of his paw, rolling it around on his tongue when suddely Bruce nudged forward and licked across Rhem's tongue, stealing most of the cum off of it.  Rhem's eyes opened wide with shock, and a bit of amusement.  "Well then, I can't say I've ever done that before."

The large panda eyed Bruce, who was slowly leaning up to him again and sniffing at Rhem's mouth.  Rhem felt his heartbeat quicken just a bit with excitement.  He opened his maw wide and Bruce didn't waste a second in moving forward and locking lips with Rhem.  Bruce's tongue slid into Rhem's mouth, squirming against his tongue and poking around the wet area.  Rhem's cock hardened in an instant as he  let out a long exhale across Bruce's muzzle.  He slid his own tongue forward along Bruce's tongue, following it back into Bruce's mouth and slithering around in there.  He could still taste the salty residue of Tornado's cum in there, which made him all the more tense, and his cock pulse.

That's when he got an idea.  Rhem pulled back from the horsie kiss and stood up, walking over to the back of the horse.  The panda gently carefully climbed over the horse's haunches and bent over, bracing himself as lightly as possible against the stallion's hips.  Rhem spread his legs out wide and eased his hips down, letting his heavy balls drag across the big cum-soaked balls of the stallion.  The panda gasped as he could feel the incredible warmth radiating from the loins of this powerful beast, whose balls were flush up against his own.  He could feel Tornado's cum soaking into the short, velvety fur that lined his ballsac.  The sensation made him groan and press his groin firmer against the large balls of the stallion, the horse's coconut-sized orbs fitting nicely between the panda's thighs as he pressed his most intimate areas against them.  Rhem leaned forward and pressed his shaft down against the base of the stallion's muscular cock, getting huge gobs of stallion cum all over his length.  He twisted his hips from side to side, rubbing his dick all over the stallion's throbbing cock until his own was covered in the thick, white cum.  Then the panda started easing himself forward and back, letting his balls gently slap up against the stallion's nuts.

Rhem held on tightly to the stallion's haunches as he rubbed and grinded their balls together.  His balls glided slickly over the cum-coated balls off the stallion, making the stallion's dick throb and jump.  Rhem pressed his cock into the little cleft between the stallion's balls and shuddered at the feeling of the incredibly warm, wet balls of the stallion almost completely enveloping his cock.  He slowly pressed his hips forward and back, sliding his slick cock over those heavenly stallion nuts.

Then the chubby panda stood up, his dick throbbing and pulsing in the cold laboratory air as Tornado's cum oozed down his cocktip, shaft, and dribbled off his balls.  He had gotten Tornado's cum all over his inner thighs and even across his taint.  It didn't just wet his fur, there was so much cum that it completely coated his own fur and obscured the black in his fur coat.  The sight of his cock, balls, and groin area completely soaked and saturated in horse cum made the panda shudder and his dick dribbled pre steadily.  He took a step forward, still standing over Bruce, his leg a bit shaky from his adrenaline pumping.  Bruce craned his head down and pushed his nose up into Rhem's crotch, getting Tornado's cum smeared across his nose.

Bruce started licking across Rhem's thighs, lapping up all of the other stallion's cum.  He licked the area very thoroughly, with long, slow licks, making sure to get all of the salty stallion seed out of Rhem's fur.  Then he moved his snout down and slid his tongue up behind Rhem's ballsac, licking across the Panda's taint.  The Panda jumped a bit and tensed up, groaning blissfully as that stallion tongue slid up between his legs again and again, taking up all the cum that was embedded in his fur.  Then Bruce slid his tongue up along the back of Rhem's ballsac, making Rhem's legs buckle.  The panda felt his legs about to give out, but before he could brace himself for the fall, Bruce brought his front legs together and locked them under Rhem's armpits, bracing him almost like a pair of crutches.  The panda felt Bruce tighten his front legs against him, locking him there while the horse continued to lick over the panda's large, cum-covered balls.  The long, slick, agile muscle of the stallion worked over the panda's large orbs, caressing them and playing with them.

Rhem could only close his eyes and stammer incoherently as the stallion licked over his balls, making his cock jump and shoot pre across the horse's snout.  Then, having licked the panda's balls clean, the horse moved his head and simply took the panda's thick cock into his mouth, clamping his lips down tightly around the base of it.  Rhem let out a loud gasp and shuddered, involuntarily thrusting his hips forward and pressing his groin firmly against Bruce's nostrils.  Bruce didn't seem to mind at all, as he started to suck hard on Rhem's cock.  He slathered his tongue over Rhem's cocktip, making it shoot more pre which he happily licked up.  He slid his long tongue down along Rhem's length, caressing the very base of it and squirming it around as he caressed the base of Rhem's cock with his lips.

The chubby panda could only groan and whimper as the horse masterfully suckled on his thick cock.  He reached down and rubbed under the horse's snout, feeling the muscles in his mouth tense and flex as the horse worked his tongue all over the panda's cock.  The horse's tongue slid slowly over the tip of the panda's cock, sending a sudden spike of pleasure straight through the panda, making him tense up and shudder as he started to hump at the horse's snout.

The panda started sliding his hips back and forth, sliding his throbbing shaft in and out of the feral horse's mouth.  The horse's maw was so hot and wet, the tongue rolling over the panda's cock and curling underneath it, Rhem couldn't help but let his head fall back, his jaw open and tongue hanging out as the pleasure simply overwhelmed any sense of rational thought in him.  He simply gave himself into the divinely pleasure feeling.

The horse's tongue slipped out through his tight lips, grinding against the underside of the panda's cock until it hooked down just a bit and slathered across Rhem's ballsac.  Rhem jumped a bit at the feeling, his cock pulsing and shooting another quick shot of pre into the horse's maw which he quickly swallowed.  The panda almost melted as he felt the horse's tongue run up and down along the front of his balls, his body going limp and falling over the horse's head.  With the panda no longer strong enough to hump into his snout, the horse started moving his head up and down, lips clamped tight around the panda's thick cock.  Rhem grunted and sighed happily as he felt the horse's lips sliding up his shaft, exposing the wet cock to the cold air in the laboratory, right before the horse's head dove back down again and the panda's cock was engulfed in a sea of warm, slippery flesh.

A thought kept creeping into the panda's mind for but a brief moment before a wave of pleasure swept it away like a sand castle at high tide.  Yet, this thought kept coming back to him, stronger every time the horse's tongue caressed one of the panda's balls.  Each shot of pre shooting from the panda's cocktip, somehow, this thought kept coming back.  And as the panda felt the imminent euphoria and explosion of orgasm, this thought somehow broke through to him like an explosion ripping through the busy midday traffic jam.

[i]Too soon![/i]

Rhem somehow found the strength to plant his paws on either side of the horse's head, pulling his hips back and stumbling back onto the lower belly of the horse.  He fell down lightly right near the base of the stallion's shaft, his asscheeks firmly caressing the shaft with his stubby tail bumping against the large horse nutsack.  His legs were spread out on either side of the horse, and all he could do is look down past his belly at at the horse's face.  His erection was standing straight up, throbbing hard and shooting pre into the air and all over his crotch and the horse's chest.

[i]So close...too close.  Have to save the load for the kinky finale[/i]

Rhem leaned forward a bit, clenching his asscheeks around the horse's cockbase, making the stallion's shaft pulse and shoot some of his own pre across his chest.  The panda tucked his legs back under him as he continued to straddle the horse's lower body, smirking to himself at the sight of the horsecock that almost seemed to emerge from his own crotch due to the perspective.

[i]Damn, don't I wish...[/i]

The panda leaned forward, laying down carefully on the horse's cock and belly.  His own cock pressed so firmly against the thick, powerful shaft of the stallion below him.  His large, heavy balls rubbed against the base of the stallion's shaft, making both males quiver a bit and shoot some pre.  The panda flexed his cock muscles, making it tense and press harder against the stallion's cock.  The large horseshaft pulsed in return, shooting some more pre from his tip, but this time the panda was ready for it and tucked his head down quick enough to lick it out of the air.  He then gave Bruce's cocktip a kiss, before he leaned up and kissed Tornado on the nose.  Breathing a bit heavy from his pulse racing, he winked at the stallion and said, "Now that's a good boy.  I would have given you more, but we have work to do today.  Kinky, sexy science work that would make any ethics professor die from shock"

Rhem carefully brought his paws down to the horse's sides, near his shoulders.  He got a good grip on the stallion and carefully pushed his hips forward, grinding his groin firmly against the stallion's shaft.  His cock was pressed tightly between his own belly and Bruce's cock, and he absolutely loved that feeling.  His warm balls dragging back and forth over the thick, powerful horsecock.  It was just wonderful, so unique a feeling to have one's most intimate areas, most sensitive areas, pressed up tightly against the same areas of such a powerful beast.  The stallion's dick was so thick, and so damned hard with those powerful muscles, almost as hard as a rock.  Bruce's flesh only gave the tiniest bit under the pressure of the panda pressing his own dick against it.  And every time it throbbed, Rhem could feel the pulse through his own dick, through his entire body even.  His body shook just the slightest bit every time the stallion's cock throbbed and shot more pre over his chest.

The panda sat back once again and looked down at his crotch.  He used his paw to press his cock down and against the stallion's cock.  Side by side, of course there was no comparison.  Rhem was of average length, but he had above-average girth that made sure his partners always remembered him the next morning one way or another.  Yet next to this beast he was nothing.  Something about that was...somehow arousing.  Like he'd always have a challenge in life, a superior, something to always battle against.  A size he could never be, so he'd have to find a way to be superior through skill or tactics.  Good.  Life would be too easy without something like that to keep him on his toes.

Rhem finally planted his feet down and stood up above the stallion, leaning over to the side slowly and half-stumbling away in a lust-clouded stupor.  He took a few minutes to catch his breath and regain his composure, running his paws over his rounded belly and sides as the adrenaline faded away.  He could smell the musky aroma of stallion and cum which seemed to permeate his fur now.  It made him feel powerful, potent, virile.  Behind him, he could hear Lisa jogging up the path to the bay doors.

"Alrighty, I'm back.  So what do we do now?"

Rhem turned to her, grinning from ear to ear.  He stood proud with his heavy balls nestled comfortably between his thick legs and under his curvy belly.  He put his fists on his hips and brought his chin up as he looked at her, "Now, my dear, it's the dragon's turn"
