I've been the personal trainer of Teryx for a while now. I've been training him for so long in fact that I know his body as well as I know my own.I love the muscle mass I've built up on him. And we always smell so virile after training.I've put so much work into our body. Is it wrong to want to partake in the fruits of my own labor? (3.1k words)

Training Teryx

For TeryxC by GhostKing

###

<He's late,> thought Teryx as he made his way to the front door. The rain dragon had been expecting his trainer for some time now. He had changed into his gym wear an hour ago. His clothes weren't necessarily tight, but they left little to the imagination.

The blue rain dragon stood in front of the mirror. He had to admit, even with his trainer's... unusual methods he had made significant progress. He even ripped one of his old suits when he tried to put it on. He currently wore a white short sleeved T-shirt with matching black shorts. They were a little tight on him; the bulk he had accumulated from his sessions left his clothes taut against his skin.

On top his head stood two long horns with the same dark blue hue as his skin. From the tip of his snout and running down to his neck was white. Boarding between the white and dark blue sections were segments of light blue. His golden mane that flowed from his brow to the base of his neck naturally stood on end. Running down the center of said mane were a series of three white horns. The top of his tail cycled throughout colors of the sunrise, from the same dark blue featured on the rest of his body to white at the tip.

*Ding dong* went the doorbell.

<Finally!> Teryx excitedly rushed to the door. No, he was not excited. He was eager to get this over with so he could get back on schedule.

He opened the door and looked down at his late appointment.

"Yo!" Lumus said with a smile. His fingers made a peace sign as he waved at Teryx.

Anyone who saw the two would have thought that Teryx was the trainer. Physically, Lumus was average at best. The wine-red dragon-tanuki mix was neither tall nor short, thick nor thin. The top half of his muzzle was a lighter shade of red. The tip of his thick tail was shaped like a leaf. His golden hair was slicked back and tied into two braids by his ear. His thick beard was also tied into three braids, one in the center and one on either side. He had two horns extending out the side from just above the temple that turned so they turned to the back. Two large wings sprouted from his back. Even his clothes are average, a loose-fitting t-shirt and cargo pants. If Teryx didn't know better, he would have sworn he had forgotten about today and rushed over.

"Come in," Teryx ordered as he stepped to the side. "You were supposed to be here almost an hour ago."

"Sorry, my last appointment went long." Teryx knew what that meant, considering what he collected as payment. He just rolled his eyes in response.

They made their way to the kitchen where Teryx had left his bag. It was also one of the least visible rooms in the house and he didn't want anyone to see what was about to happen.

"So, shall we get started?" Lumus asked, breaking the silence.

"Yes, we're already late." Teryx tried to sound like this was just another business transaction. But that was a lie. He looked forward to this every week. Although he told himself it was the workout, he knew it was really about what was about to happen.

Teryx leaned forwards over the table and braced himself. Lumus stepped up behind him, pressing their legs together. He laid his tail on top of the larger dragon's and just stood there.

"I'm going in," he notified Teryx.

Warmth.

A comforting warmth was coming from the back of legs where Lumus made contact. Lumus then pushed his right leg into the bigger dragon's. With it, the warmth became a more intense loving heat and its origin moved from behind to within. After regaining his balance, his left leg followed suit. The same warmth could be felt from his tail. This warmth grew as well as the red one sank into the one below. Lumus's lower half was completely encased inside the larger Teryx.

"Need a moment?" Lumus asked after noticing Teryx's unusual breathing.

"I'm... fine..." Teryx said between breaths. His legs and tail felt full.

They felt warm.

They felt complete.

"O.K. then..." Lumus placed his hands on Teryx's wide back, just inside the shoulders. Teryx had to stifle a moan as they pushed in. Like before, the warmth started at the point of entry, but this time it shot through like a wire down his arms and pooled in his hands. As more of Lumus's arms sank in, the pooled warmth grew quickly, flowing up through his arms. As it grew, Teryx's control lessened. Soon all of his limbs had been surrendered to Lumus's heat.

Lumus's torso was now resting on Teryx's back. For a brief moment, one could feel the other's breathing both as one pressed against another and as the other. This too was cut short as the red mass sank through the shirt into the inviting blue bulk underneath. The heat exploded into his back and joined his limbs together. The heat has taken over everything but his head.

This session was feeling odd. Lumus's heat was changing within him. Usually, he could feel the heat next to him, embracing his spirit within the confines of his flesh. This was the first time he felt it inside him.

Teryx's thoughts became fuzzy as Lumus made his final push. Like with his arms, the heat shot though his head and stared in his snout. It flowed not only from the snout but was rising up his neck too. The last of Lumus's head had encased itself with the rain dragon and with it, the heat took over.

Bliss.

For an instant Teryx was lost in utter bliss. Lost in the heat. The heat was all around him and within him as well.

But the heat quickly subsided, and his consciousness returned to reality.

The reality of his tongue moving around his mouth on its own. The reality of his hand rubbing his chest controlled by another. The reality of his body now standing normally as if another person hadn't just sunk inside.

With his mind back to normal he started to realize something was off. As if waiting for that thought, "Teryx" smirked.

He pulled down his shorts' waistband low enough to pull out his dick and balls. Lumus looked at the tools that came with this body. Contrary to what his bulk might convey, Teryx's dick was just average for his size and not eye-wateringly huge. That was about to change. Unlike the rain dragon, Lumus's dick was housed inside a slit on his crotch. This difference in anatomy was apparently important enough for a normal possession to not align the two properly. All that means is it had to be done manually.

Lumus's spectral body had fully matched Teryx's physical one. That would put his slit right at the base of their cock. Lumus grabbed hold near the base and started to will his dick out. As it emerged, Teryx could feel it stretching his member. Thanks to Lumus keeping his eyes fixed on their crotch, he could see the head of the invading member widening his own shaft by a couple of inches. After it passed the rest of his length stretching past its original size tightly hugging the dragon-tanuki's thicker shaft. The added girth made the ridges along the bottom of his shaft more pronounced. He would be moaning if Lumus hadn't taken his voice. Unfortunately for Teryx, it did not stop once it reached his tip. It continued on, stretching Teryx not only in girth but in length. It stopped about an inch out. Thank God Lumus was soft. Lumus was hard the first time he stretched him. He thought his dick was going to pop like a balloon. Lumus shook his new member, feeling the increased weight he gave it.

Then the balls dropped. Lumus never cared enough about his own anatomy to learn where they were for him, but they fell into Teryx's sack hard. The tanuki ancestry showed as Teryx swelled to double their original size. His libido suddenly grew with the extra testosterone suddenly running through his veins. Lumus would take care of that; this was his norm, after all.

"There we go, now I've got a proper dick for my size." Teryx said. Or, rather, Lumus said with Teryx's voice.

He tucked their privates back inside their shorts and made their way to Teryx's bedroom. He knew he would be able to find a full-length mirror there. There Teryx was made to check out his reflection. Everything was the same as before, but now Teryx's mane had extended round the rest of his face forming a beard in the same style Lumus wore. He learned long ago that no one else could see Lumus's features on his face. That was for him and him alone. What others would see though is his new obscene bulge in his pants. Since Lumus was not looking at it, Teryx could only see it from his peripheral vision. Even then, it was like night and day.

Before leaving Lumus lifted Teryx's arm, pulled open the sleeve of his shirt, and sniffed his armpit.

"The Hell is this!?" He asked angrily.

<What?>

"Flower scented deodorant?"

<It's not flowers, it's->

"Anything that's scented might as well be flower scented. I'm gonna have to work you extra hard today to get you smelling right," he grumbled.

He grabbed the bag of Teryx's change of clothes and headed for the gym.

Lumus was not kidding about the extra work. He worked that body for almost the entire day. It started out like usual, but he didn't show any signs of slowing when nearing the normal hour mark. Lumus started to become less responsive to Teryx's concerns and started ignoring him all together after two hours had passed.

Teryx was always one of Lumus's favorites. He responded well to his training, both in terms of results and performing the exercises themselves. They both quickly became eager for their sessions. Teryx loved the feeling of the workouts, his body being molded into perfection with Lumus right there in him, supporting him. Lumus was all too happy to help. Lumus felt a potential in Teryx that he didn't get in his other clients. They just didn't respond the same way. They didn't fire him up in the same way. He needed to push Teryx to his best.

Teryx had passed the point of exhaustion a while ago, but Lumus still kept going. The odd heat was moving his body for him. Even the routine itself was ludicrously intense. He was lifting well past his previous records with ease. He was changing machines purely out of boredom. Only Teryx could feel his body beg for rest. Lumus only stopped for water and to use the restroom. At this point he was sure he only got water just so he could sweat more.

Every trip to the restroom came with a "scent test". He would shove their hand in their pants and give his length a couple of strokes (the feeling of his cock being stretched further sent waves of pleasure throughout Teryx's body) and gave the hand a sniff. Then he would check his armpit, shoving his head into the sweaty cave and not only huffing the musky air and giving the occasional lick so Teryx would taste his own armpit sweat. He could not get enough of Teryx's natural scent. He needed this smell. He needed to have it whenever he wanted. There was only one way to do that; He needed to be the source.

They stood in front of a mirror when Lumus finally stopped for the night. His shirt was drenched in so much sweat he looked like he swam with them on. Lumus was having fun watching his pecs, pumped from the work out, bounce and the shirt sticking to them like a second skin. He tried some other poses, each showing off another muscle group. He seemed to like what he saw. Unlike the real dragon, the one in the mirror still showed the usual changes. The hair smoothly flowed down to his upper back, and he had a full beard tied into three braids. He had a fang sticking out from behind his upper lip in each corner of his muzzle.

He went to the locker room and toweled off before changing into another pair of T-shirt and jeans. He skipped taking an actual shower because he [i]finally[/i] undid what Teryx had done. His post-workout musk was amazing; it would be a crime to get rid of it early.

<We're going home now, right> Teryx pleaded as they left the gym.

<No, we've got one more, hopefully final, progress check to do.> Lumus's voice was off too. It lacked is usual playful demeanor and instead had a slower, more authoritative tone.

<Final?>

<Oh, you'll love this...> Lumus added ominously and pulled out of the parking lot.

Teryx didn't know where he was. Or, more accurately, he was too tired to care about where he was. He couldn't move. Shackles bound his arms above his head and spread his feet keeping him in a star pose while lying naked, face up on the bed. Besides, the inferno that kept his body moving left after securing him in place. Now nothing was keeping him from feeling the exhaustion from his earlier work out. All he could do was keep staring at his surroundings.

Eventually he heard a click as the door unlocked and in walked a muscular wolf.

"Sorry to keep me waiting. He was a surprisingly hard find." His speech had a familiar eerie slowness.

The wolf locked the door behind him before making his way to the bound dragon. He ran his hand along the dragon as he made his way towards his head. He stopped once he reached a pec and gave it a firm squeeze.

"Flex for me." Teryx couldn't even if he wanted to.

"Who... are... you?" He weakly managed to ask the strange wolf.

"Aww, you don't recognize me?" The wolf looked hurt. "I've only been building this," the wolf gestured to the rest of the dragon's body, "for years now."

"L- Lumus?"

"For now."

"'For now'?"

"That all depends on how you do on your final."

The Lumus-possessed wolf crawled onto the bed with Teryx. He straddled the rain dragon, placing a hand on either side of his chest and knees on either side of his waist.

"I tried this at the gym, but one can never truly know how others perceive them." He lowered his head and licked the sweat from Teryx's chest from the bottom up in one slow motion. "This way I can test everything."

He gave both pecs a squeeze before moving on to one of his outstretched arms. He ran his hand across the skin, feeling the bulky muscle underneath. He then buried his head inside the exposed pit. He stayed there for a minute, taking his scent in. This was the scent only a big, powerful man could make. This was the scent He would soon make.

He pulled himself away, he had more to examine. He went down to Teryx's tree-trunk legs. I bet I could even fuck someone while carrying them with these things he thought. He gave the thighs another squeeze to feel their firmness.

Both Teryx and the possessed wolf were loving this. Teryx's deep moaning was starting to get loud. The wolf's cock was fully erect by now, unable to do anything about it with the inferno inside deciding his actions.

Lumus spread Teryx's legs out a little more to get at his taint. He placed his nose at the base of the rain dragon's dick right above the balls and gave an audible sniff. The dragon's ridges slightly shifted along the snout underneath as his shaft pulsed with need. Without moving his head, he licked clean whatever he could reach with his tongue. Right before he could cum, the wolf stopped.

He crawled over to Teryx's head and whispered in his ear, "congratulations, you passed."

"What... did I... pass?" he asked, still on the verge of orgasm.

"My body test." Lumus stated as he began to undo the shackles holding him in place. No longer bound, Teryx's hand immediately flew to his dick to finish but was blocked by the wolf.

"Not yet, A: that's my orgasm you're trying to take from me and B: Not with that dick."

Teryx had forgotten his shaft shrank back to its normal size now that the other shaft was not inside.

The wolf walked over to a chair in the corner and sat down. Then the red dragon-tanuki stood up quickly unceremoniously exiting the body. The wolf was left slumped over in his chair.

"Don't worry about him, I just put to sleep for a bit," Lumus said before making his way back to the dragon still lying on the bed. "I've spent so much time on this body. It's more mine than yours. So, I'm going to take what's mine."

Unlike every other time he entered the bigger dragon, this time was quick. He dove into his chest, letting gravity push the rest of himself in. In less than a second all that could be seen was the tip of his tail sliding between his pecs.

Teryx's body was thrown into chaos. The heat was back. Then it fed off Teryx again to become the inferno that got him in this situation. But this time it wasn't slow and careful, it was fast taking over his entire body almost instantaneously.

He was lost in bliss again. But what brought him back this time was the stretch. This time, Lumus was hard. This meant that his dick was stretched to his full length and thickness almost all at once. Despite this, the throbbing heat of the bigger shaft finally pushed Teryx over the edge and he came. Teryx scooped the cum off with his hand before licking it clean.

"That's much better," Teryx said. "Don't you agree, Body?"

The original Teryx didn't respond. He was lost in the blissful inferno within.

"Hah! Of course, you have nothing to say; bodies can't talk."

Teryx grabbed the clothes he was wearing earlier and headed to the bathroom before putting them back on. He checked himself out in the mirror. The reflection showed Teryx's wine-red red skin contrasted against his golden hair and beard. He'll have to remember about the white horns not showing up for him. His abs and pec and top half of his snout were the same shade of a light red. His fangs were still peeking out.

He put on the clothes and headed out. The wolf would be fine. Teryx had a new body and new life that came with it to enjoy.
