For the second time in a row Shelby had to watch out as kids ran past him in costumes, trying to score the last candies they could before the trick or treating time came to a close. He was only dressed in his usual blue jeans and a shirt as he had no reason to do the same as an adult. While he was fond of the fall season and everything that came with it he unfortunately was far too old in order to do much and with the apartment complex he lived in there wasn't even the opportunity to pass out candy since it was code locked. As he opened that door and walked inside however there were a few that attempted to celebrate the season with paper cut-outs of pumpkins and leaves, which was the extent of the decorations that management would allow to be put up.

"At least there aren't any kids here that would be bummed out by the prospect," Shelby said to himself as he made his way to the elevator and pushed the button for his floor. "If I was a kid that lived in a place like this I would go door to door on every floor and rake in the candy... not that it matters to me."

Eventually the elevator got to his floor and opened with a loud ding, the sheep moving through and heading to his apartment. Though it was a larger building there were only eight doors in total since the apartments themselves were supposed to be high-end, with his being at the end of the hall. That meant that it stood out when he passed by one of his neighbors and found an actual jack o'lantern sitting in front of the door with what looked like chocolates spilling out of it, along with a note that read trick and treat and to take as many as wanted in order to spread the Halloween cheer. As Shelby looked at it he saw that the owner had made or bought enough chocolates to keep the entire building in sweets for the weekend, and since management would probably confiscate it soon anyway for blocking the hallway he grabbed a handful and took them with him back to the apartment.

Just as he finished putting the candies in his pocket he felt his phone vibrate, releasing the chocolates and grabbing it to see who it was. It was his friend Marshall asking if he could come over for a bit; the black and white scaled dragon lived a floor below with his stallion partner Hank and the three of them were good friends, though he knew Marshall for much longer since the horse had only moved in with him a few months ago. He quickly texted back that he had just gotten home and that he could come up in about twenty minutes while he walked inside his apartment. After a quick confirmation Shelby put his phone on the counter and began to get ready for the arrival of his guest starting with pulling his coat over his horns.

As he did Shelby heard something fall to the ground and when he looked down he saw the candy he had collected earlier lying there on his floor. The sight caused him to remember the others and he dumped them all out on the counter next to his phone, seeing that he had managed to grab nearly a dozen upon passing. He felt a little guilty having so many before he remembered just how many were there for the others, but he remembered that they would probably be gone soon anyway by management. As he made his way to the shower he unwrapped one and popped it into his mouth, and as soon as the taste hit his tongue his eyes widened slightly in surprise.

While the sheep had been expecting just a normal chocolate what he got instead was something flavored exactly like tiramisu, causing him to let out a noise of excitement as it melted in his mouth. Not only were they expertly flavored but the texture was amazing too; it was definitely not expected from candy that was just lying out in a hallway, and after he had gotten naked to take his shower he left the water running to go back and grab two more. He ate them both while waiting for the water to warm up and though he wanted to run back and get the rest he took a deep breath and calmed himself, reminding himself that he would probably be getting some sort of food with Marshall once he had arrived.

As he stepped into his shower and let the water cascade over his body he felt himself shivering slightly despite the warmth of the water, the sheep realizing that a tingle of pleasure had started to radiate from his stomach as he washed off the dirt and grime of the day from his fur. The taste of that candy was still in his mouth and he found himself licking his lips as his hands went to start shampooing his body. Even though he had resigned himself to only having those three and no more he felt an almost longing feeling in order to have another one. It made him wonder what was even inside those treats as he fully lathered himself up and covered his body with the soapy bubbles.

Just as he was about to wash himself off Shelby suddenly felt his stomach gurgle and his hands went down to it. While he wasn't in any discomfort it started to feel like his insides were shifting, something that was definitely not normal as his fingers ran through the soapy brown skin of his stomach. It felt like his flesh was... rippling, moving and bulging under his fingers like he was doing some sort of workout despite just standing there. He let out a soft moan as his abs contracted and the sensations spread to his upper chest and sides, causing him to shift forward until he was underneath the stream of water once again.

As the soap washed away from his body the sheep's eyes widened once more, causing him to gasp when the suds disappeared and revealed his abs. Though he had always considered himself to be fit the stomach that he was staring at looked like he had gone to the gym for years and had only done crunches. The eight-pack that he sported was practically bulging and the more he stared down at his chest the more he could see the changes weren't just confined to there. His gasps turned to pants as he watched his pectorals thicken to match and his sides practically sucked in until they were almost pure muscle.

Shelby felt his back press against the glass as he tried to figure out what was happening to him, though the transformation wasn't just content to stay in his midsection. He groaned loudly as his shoulders popped and expanded, watching as his biceps swelled and his forearms lengthened while the fur that covered them grew thicker. something similar was starting to happen to his thighs as they became almost bloated with muscle before the excess mass traveled down his calves and feet. The sensations were almost too much for the sheep to bear and as he gripped his expanding hands against the glass wall of his shower a new change was happening that nearly floored him right there.

Up until that point his maleness had remained unchanged, but as the deep throbbing of his new muscles caused pleasure to spread to his body he watched his cock start to grow. His pants matched the throbs of his shaft as it quickly grew to its usual length, but before the sheep could rap his hand against the shaft it surged with new growth. Shelby watched with his mouth open in sheer awe as the sensitive brown flesh grew in size and girth until he was staring at something that most porn stars would love to have. That was combined with the rest of his increasingly athletic form as the sheer pleasure he got from his transformation caused him to cum without laying a finger on his member.

The water quickly washed away his seed as the muscular ram slid down to the floor of the shower, panting loudly as he looked down at himself. The body that he had didn't feel like his own but as he ran his fingers along the ridges of his enhanced physique he could feel himself shiver from the touch of his own body. Not content to just stare at himself though once he had recovered from his orgasm he stood up and turned the water off, then immediately went out of the shower and towards his bed room. After nearly hitting his head on the top of the door frame he found his full-length mirror and finally got to fully see himself.

Though he didn't have a scale or anything to measure his height the sheep knew that he had at least gained enough height on his new frame to push himself past the six-foot mark and gained a hundred pounds of pure muscle on his previously slim frame. As he gave a flex and watched the reflection move he almost felt giddy, watching his muscles pop and shift with his movements. He felt... powerful, like he could take on the world, and despite the bizarre changes that had happened to his body he started to laugh in sheer glee. It continued on for a minute and when he looked at his own face there was an almost manic expression on it, though that didn't concern him as a grin spread across his face...

He needed more...

Without bothering to put on any sort of clothes Shelby ran back and grabbed the rest of the candies from his counter, only taking the second to unwrap them before putting them into his mouth. As he swallowed the sweet tiramisu-flavored candies he could already feel the strange chocolates starting to do their work, the sheep's smile growing wider as he flexed his arm and watched it thicken right before his eyes. With the remaining candies sliding down his throat the sheep huffed and began to move back towards his couch, feeling his entire body twitching and stretching with every step that he took. Had he bothered to put on any clothes they probably would have ripped off of his frame at this point as he flopped down on the couch and heard the frame groan in protest underneath him.

The sheep's body was quivering and writhing as the candies began to take effect, this time the transformation more immediate and drastic than the previous time. For a second a level of clarity entered Shelby's mind and he began to wonder if he had accidently overdone it, especially as he turned over to his stomach and saw his forearms become thicker than his legs. But the sensations of pleasure quickly suffused through his mind and that look of fear became a smirk as he realized just how good it felt, how strong he felt from those candies as his body continued to twitch and stretch. His breathing grew more intense and as he began to chuckle once more he could feel his voice deepening.

"Trick... treat..." he muttered, Shelby almost feeling like someone else was saying it as his muzzle even began to stretch as his skull was growing to match his new body. "Trick... and treat..." his last word was cut off by a gasp as he felt something pushing out of the top of his head, a second pair of horns appearing just behind his first while his originals began to curve and lengthen as well. Was the candy the trick, or was this body his treat as he watched his hips and sides lengthen while his shoulders pressed against the back of the couch.

Shelby let out a roar as his entire body seemed to push out at once, fangs growing from his muzzle as the rest of his form exploded with new muscle. He was becoming so big that he could no longer fit on the couch anymore as he rolled off and felt to the floor, still groaning and shaking back and forth as his shoulder blades pushed out of his back. As Shelby looked up the fanged grin on his face grew wider as he felt something push out of his spine, a row of spikes forming down form his neck to his tail as he felt his feet and hands grow while pushing against the floor. Just like before his cock was the last of his body to be affected, and as the corrupted treats continued to fill his mind with lust and pleasure he could feel it practically pressing against the ground as he turned over and began to stroke himself in earnest.

The nearly seven-foot tall sheep was thrusting his hips up in the air as all he could think about was needing more. More muscles, more growth, more candy... it spun around in his head like a top as he stroked his new foot-long cock. Even though he had a physique that would put most body builders to shame it wasn't enough, and even with his body still mutating and growing the corrupted sheep knew that soon it would come to an end. As Shelby opened his eyes once more, revealing the disappearance of the pupil, he suddenly remembered where he could get all the candy he wanted as he stretched his heavily muscled frame and slowly moved towards the door...

Less than an hour after Marshall had called Shelby to see if he wanted to hand out the dragon found himself walking up the stairs towards his floor, texting to tell the sheep that he was on his way. Since his partner worked the later shift it wasn't uncommon for the two to hang out together while he waited for the horse to get back. When he got to the door of Shelby's floor however he looked at his phone and saw that he hadn't gotten any sort of response back. While that was a bit unusual the dragon just shrugged and thought that perhaps the sheep wasn't at his phone, which just meant he would need to walk.

As he opened the door however Marshall stopped when he saw something that he hadn't expected to see; which was a very muscular, very naked man that appeared to be collapsed in front of their door. There were also sounds coming from the area that he could hear even with the distance between them that made him wonder if the guy was choking on something. "Excuse me, sir?" Marshall asked as he closed the distance between him and the other man. "Do you need me to call... an... ambulance..."

The phone that Marshall had been holding dropped to the ground as he got close enough to see that not only had the huge behemoth of a man laying there looked somewhat similar to Shelby, but that he also had his head buried in a Jack O' Lantern before it turned up and looked at him with solid white eyes. This creature looked like something out of a horror movie, but as it let out a hiss it caused the dragon to turn and run back down the hallway. Before he could even take a step in the opposite direction however the hulking sheep man had turned around and pinned him to the ground on his back.

"Trick and treat," Shelby said in his new deep voice as he looked down at the dragon, who just stared at him in shock as he gave him a fanged grin. "Time to spread the Halloween cheer." Before Marshall could even process what had been said to him he suddenly saw the candy-covered tongue of the creature slither in front of his muzzle like a snake before pushing into his maw. The corrupted sheep watched in sheer glee as he felt it slide past his lips and deliver the treat to his friend so that he could share in his joy.

Though there were a few muffled grunts in the beginning the effect immediately started to take hold, watching the dragon's eyes suddenly become unfocused and glassy. It didn't take long until Shelby could feel Marshall start to suck on his tongue, trying to get more of the candy into his gullet. As the naked sheep man continued to press against the dragon's body he could feel his form starting to shift quicker too; normally Marshall wore looser clothing because he was a bit overweight but as the mystical candy took hold he could already feel his scaled form starting to stretch and grow. As Shelby felt the legs that he was on top of inflate like a balloon he pulled his tongue out of the dragon's mouth and reached back and grabbed another large handful of candy, pushing it right into the dragon's maw as he chomped it down greedily until there was nothing left.

With Shelby's own body filled with the corruptive candy there was another need that he had to take care of, picking up the dragon while he still could and pushing him up against the wall. Though his body was already starting to grow once more Marshall was quickly catching up, the two of them grunting and grinding against one another as the seams of the loose cargo pants that the dragon wore began to split at the seams. Even though they were both in the hallway neither of them cared as Shelby took his clawed hands and ripped the pants right off where the thickening tail of the other male was. Seeing their muscular forms both growing, watching their bodies ripple and swell was almost too much for him as he pushed his cock between the meaty cheeks of the dragon.

Even with the intense sexual euphoria coming from their changes Marshall let out a gasp and looked down at himself, groaning as his arms pressed against the wall grew more impressive with every second. "Wha... what's happening to me..." Marshall managed to say, the corruption that had consumed Shelby still eating away at him as he his voice began to deepen. "What have you done... Shelby..."

"This is your trick... and your treat..." Shelby replied with a fanged grin, watching the dragon groan louder as he pushed in even deeper underneath his tailhole. "Just give in to the candy, let it consume you just like you consumed it. Your treat... and your trick..."

"Trick... and treat..." Marshall repeated, his eyes closing as his head began to shift while being pounded into. He continued to repeat those words as his lips curled up, at first in a sneer as his already sharp teeth lengthened and then into a grin as a second pair of horns grew right next to the first. The grunts and groans that came from the dragon began to become interspersed with chuckles, then full on laughter as he opened his eyes again to reveal they were the same solid white as Shelby.

"Must... spread the Halloween spirit..." Marshall said, twisting his more powerful body around and causing Shelby to come down with him as he looked at the chocolate covered pumpkin there. "I need more... I have to have more! More muscles! More growth!"

Before Shelby could do anything the dragon had already started to use his lengthening tongue to lick every last drop of candy out of that container, and had Shelby not been balls deep in his friend he probably would be doing the same as he watched their miraculous sweets disappearing in the dragon's maw. His own body had continued to grow however from his previous gorging, his body sculpted out of pure muscle that made him look like he had been a statue constructed by an artist with a muscle fetish. His cock had also grown more in length too, continuing to push deeper into the dragon even though he hadn't moved his powerful hips to do so. As Marshall finished off the last of the candy he growled and tossed the container aside, bucking backwards and causing the muscle sheep to fall to the ground.

"My turn," Marshall said with a toothy grin as he leaned forward, his own abs still growing more underneath his scales as his spine popped with new height. Before he had been introduced to the candy he would have been shorter than the corrupted sheep, but as he continued to grow bigger they were eye to eye with the dragon still pushing more height from his expanding form. As their lips met once more and their muscular chests pressed together Shelby could taste the tiramisu candy on the other man's lips, causing him to moan and lick as he felt something press against his own hole. His thick legs had been raised up in the air and both were too far gone in the passions of their lusts to do anything different then let their new instincts take over.

As Shelby felt the nearly two-foot long cock stretch open his hole both were suddenly stopped by the sound of a door closing. At first they thought that it was a neighbor that had heard them as they looked up and around, only to find that the hallways were still as empty as ever. What they did find however after untangling themselves from one another was that instead of the one empty pail full of candy there were now two pails filled to overflowing with more of the chocolate, the two giving one another a fanged grin as they knew what they had to do now...

It was the middle of the night when Hank finally arrived home, the horse breathing an exhausted sigh from his shift at work as he made his way towards the apartment building he shared with his partner. The time for trick or treaters had long since passed and he found a different group of people that were out, adults that used the Halloween holiday to have parties, dress up, and drink. Since Hank was none of those he just wanted to get home as soon as possible and see what his dragon was up too before passing out. As he entered his building however he noticed something unusual that wasn't there when he left; it looked like someone had taken dozens of empty candy wrappers and had spread them along the floor of the building.

"Management isn't going to like that," Hank said as he went to the elevator and pressed the button for his flower. "Probably going to get a letter in the mail tomorrow, they already hate Halloween enough."

Once the elevator had arrived the horse stepped onto it and went up to his floor, only to be once more surprised when it opened again and found similar wrappers once more. Had someone done this intentionally in order to make the building manager angry? It wasn't something that he was particularly wanting to be a part of and hurried along towards his apartment. As he passed by a few doors he was shocked again to find that several of the doors were still somewhat open and he could hear... very loud activity of a carnal nature coming from them.

Perhaps this is how this building celebrated Halloween, Hank thought to himself as he finally got to his door and opened it with his key. Though Marshall had warned him that the building wasn't really into the holiday perhaps that had been a ruse, or maybe it was just something that the dragon didn't participate in. Either way as he entered the dark room he was going to be sure to ask about it when he saw him. When he went to turn on the lights for the living room he frowned when the strangeness continued in the form of none of the bulbs coming to life even after flicking it several times.

"Marshall?" Hank called out as he took off his coat and slowly moved through the darkness towards the next light switch. "Are you home? I think something strange is going on in this place."

Before he could reach the next light the stallion bumped into something that wasn't there before, tumbling backwards and falling on his rear as he tried to adjust his eyes to see what he had just hit. "Better be careful," Marshall said from the shadows, making it clear that it was the dragon he had run into. "All sorts of tricks and treats going on tonight."

Though he knew that it was the dragon's voice something felt... very off about it, like he was speaking through one of those devices that made one's voice deeper. As he tried to get up he suddenly felt Marshall's hands press against his shoulders and keep him there as he began to smell something sweet hovering around his nose. "Is that... is that what I think it is," the horse said, reaching forward and feeling the scaled thighs of the other male. "Oh my, uh, I didn't think you were that into Halloween."

"I'm just helping spread the Halloween spirit," Marshall replied, nudging the chocolate-covered cock to the stallion's lips. "I prepared this treat special for you."

Though Hank was tired from his day at work he didn't want to just throw the hard work of his boyfriend back in his face, plus that chocolate did smell really good. He decided that the dragon deserved a blow job at this point at least and began to lick against the candy-coated shaft, only to realize even in the darkness that there was something strange about the entire thing. As he licked down the entire length eh felt that his own muzzle had to go far further to reach the base, causing him to back away slightly while licking his chocolate-covered lips. He could also start to feel something happening in his stomach, a tingling sensation he didn't expect to have as he opened his mouth to ask what was going on.

The horse wasn't able to get out his question however as a second pair of hands suddenly wrapped around the back of his head and pushed his muzzle onto the thick cock, causing the stallion to snort as it stretched his maw. The entire time that Marshall had been standing in front of him Shelby was behind, both of the muscle hulks smiling as they finally gave their trick and treat to the last member of the apartment. They could already see the candy taking effect as the horse's eyes rolled into the back of his head while his hands grabbed against the thick thighs of the dragon in front of him. Though they could both see rather well in the darkness the sheep moved over and twisted the bulb so it would light up as the dragon moved the stallion over towards the couch.

Both males had been anticipating this moment ever since the candy had taken them over, putting the horse on his back and stripping him down while Marshall continued to keep the horse's maw on his shaft. When they had gotten down to his underwear they could already see the fabric straining as the horse's cock grew erect. The stallion worked in an office and despite his frame was quite skinny, but with a handful of chocolates they had already gotten into the horse through the dragon's cock they could see his thin build start to bulge and contort. There was one thing that Shelby wanted to do while watching their newest convert grow, straddling the thighs of the horse and pushing the head of it against his own tailhole.

Hank's shaft was already completely erect by the time that Shelby had started to slide down on it, the corrupted sheep pushing his thick rear down so that he could get as much of it inside of him as possible. He didn't just want to see the horse grow, he wanted to feel it inside of him as the flat chest of the male practically inflated with muscle. The second he got to the hilt he sat there and grabbed onto the thighs of the equine, feeling them quiver under his grasp as the candy took effect. They didn't just want some muscle stud either, as Marshall pulled his cock out of the maw of the horse he quickly replaced it with a handful after handful of candy.

With the pleasure from one male sheathing his cock and the other one doing the same in his throat after he had swallowed it was clear they wouldn't need long to corrupt this one, especially when Hank's eyes opened and they saw the iris and pupil were already gone. He would soon be just like them, ready to go out and serve tricks and treats to those who wanted them as the dragon began to bulge the horse's throat out. They weren't the only ones either, they had spent a long time waiting for Hank and had made sure that the others tasted the sweet candy so they could do the same. Shelby gasped and let out a loud grunt as the growth surge hit the horse's cock, leaning back as it practically bulged out his muscular stomach while the entire couch shook with Hank's growth.

It didn't take long before the shifting and undulating muscle of the horse's body began to settle down, the skinny man replaced with a hulking beast as the cock inside of the sheep throbbed hard. "Trick and treat..." both Shelby and Marshall began to chant, their white eyes glowing as Hank joined in the second the dragon pulled his cock out of the horse's maw as they knew that outside that apartment there were multiple buckets of candy waiting for them. It was time to spread the Halloween spirit...
