#143 of Transformation Stories

This one was way overdue to be posted, but this is the perfect day to finally get the job done! This commission for Damakoes takes place on Halloween night, and it's every bit as spooky as you would hope!

The aforementioned hybrid finds himself addled with frustration, thanks to the pandemic. Without a Halloween party to attend, the dragon-wolf decides that he's going to wear his costume and get some mileage out of it anyway...and it turns out that the costume is happy to abide the idea.

It's been waiting just as long as Damakoes, and as he places the extra heads on his shoulders, he feels an almost instant connection with their fake flesh.

Is it really all that fake? Or is the sinew growing between his neck and the new heads all in his head? What about the rippling muscles, extra limbs, extra cock and brazen, sexual appetite?

It's hard to say...

2020 was perhaps the most selfish year that most people could recall, and even those who weren't hit by the myriad of problems that came in the first half of the year were starting to see things taken away by the second.

It just so happened that Damakoes found the perfect Halloween costume the year before, and when he ordered in November of 2019, he saw it in his closet almost every day, building up an impossible sense of anticipation.

He wasn't surprised when he got the text message saying that the party was cancelled, but he couldn't help the disappointment that came from reading it.

"Thanks anyway. Stay safe," he repeated, as his thumbs swiped over the screen and delivered the message. He was grateful that the tone of his text wasn't strong enough to convey just how broken up he was inside, and as he stood at the closet for what felt like an eternity, the idea of having wasted all that money and time was pushing a slump into his shoulders.

It would have been the best one I ever wore, he thought. Everyone would have loved it...

As much as he was excited about impressing other people with his impressive taste in costumes, Damakoes was mostly disappointed for himself: there was an understandably selfish moment of frustration that came thereafter, as he bemoaned the missed opportunity.

It wasn't the first thing that the cursed year had taken from him, but as he looked upon the costume with thinned lips, he decided it would be the last.

"You only get to wear it for the first time once...and I'm not waiting another year for my perfect moment," he declared, as he pushed angry digits into the buttons on his shirt. The costume didn't require a top, and he felt it would look that much better if he didn't have a t-shirt on, given how much more presence that would lend to the cuffs that were soon to grace his wrists.

He'd wear the costume all by himself, if that was the only way that he got to enjoy it; social media wasn't quite the same as having people with him, but the canine could think of plenty of folks who would be excited to see the big surprise he'd been talking about all month, even from a distance.

Tossing his phone back to the bed and throwing his shirt to the floor, Damakoes moved with aggressive purpose, even in something as simple as pulling the outfit from its hanger. He couldn't help his frustrations venting with his every move, but as he pulled the pieces from the hanger and slapped the cuffs on his wrists, he was already starting to feel a little better.

"Hello, gents. Pleasure to finally make your acquaintance," he joked, speaking to the pair of artificial heads as if they could actually hear him, much less that they could respond.

They were carved from foam and then wrapped with a special latex that made them feel incredibly similar to real, uncovered flesh, and each one was fitted with a strap so they could cross on Damakoes' chest without sticking out too much.

The large swath of black fur upon his underbelly was perfect for that part of the outfit, keeping the straps far less obvious than they would have been. As he fastened each one in place, the heads climbed up from his back and rolled over his shoulders, until a pair of carved, fitted necks settled against either side of his collarbone.

False, broken chains hung from his bracelets, fake blood coated the fangs of each of the fake heads, and Damakoes was ready to frighten anyone foolish enough to come to his house that night with an absolutely _terrifying_Cerberus costume.

"Sorry we don't have any guests to test you guys out on," Damakoes muttered. "For what it's worth, just looking in the mirror, I'd never know that you were fastened on like that...you look ready to take a bite out of the spookiest night of the year!"

Props could only do so much to look realistic on their own, but Damakoes was happy with the ones he'd purchased, and having to wait so long to finally wear them kept a hint of rose in his proverbial lenses.

The longer he stared at them and admired their presence on his shoulders, the more he felt like they were going to make up for the lack of other company in the house that evening, and they were plenty good enough to take downstairs for the start of the monster movie marathon that he'd planned out in advance.

Walking down the stairs became a bit of a trudge without a host of people there to frighten, and the couch would feel oversized and empty without friends on either side of him to share in the cinematic experience, but Damakoes was happy to entertain in the theatre of the mind: as he neared the landing of the staircase, he lifted his arms and found the prop heads moved with perfect fluidity, aiding in their realism and giving his shoulders a full range of movement.

"Can't you just imagine it? The look on their faces as we all howl out at them and spell their doom?"

As a matter of fact, we can...

Damakoes was just as guilty as anyone else of letting his thoughts wander from time to time, and he was skilled enough to change the tone of his internal dialogue at will, but he didn't remember doing so when the voice in the back of his mind changed.

Furs bristled at the back of his neck as he took in a breath and held completely still, but all that followed was silence; even the house itself refused to creak.

"Glad we're all in agreement on that, then," he murmured sarcastically. "Do me a favor and warn me next time before you decide to scare the living hell out of me, okay?"

The walls around him couldn't answer him, and the stairs could only offer the mildest whine under his approach as he descended them, but by the time he reached the bottom step, he could feel something else tickling his ears, prompting him to listen for that distant, yet eerily nearby voice once more.

You're not the one we intend to scare. You're a part of the act, aren't you?

Damakoes whipped his head to the right, feeling the voice was stronger on that ear, but when he looked, he only saw the living room. Doubting his own spatial awareness, he took a glance to the left, but the kitchen was empty, just as he expected it to be.

"So it's coming from between the ears," he groaned. "Just my overactive imagination trying to turn the worst Halloween ever into something a little more interesting; guess I can't blame it for trying. If this year were anymore disappointing, even putting on this costume would have felt like a waste of time."

There was just enough doubt in the back of his mind that Damakoes was fine with standing in the landing and waiting, as if he was begging the voice to call out to him again.

He was sure that he would hear something if he just waited long enough, but the longer he stood there, the sillier he felt for believing that anyone was talking to him in the first place.

"Well, you guys are still gonna love the movie marathon I've got planned. I know some of these classics haven't aged all that well, but it's all in the spirit of the season, y'know?" he dropped his concerns right there at the landing and addressed the heads like they were his friends, knowing they were the only things he'd have a chance to speak to that evening. "Besides...they're classics to me, but it's not like the two of you have ever seen them before!"

Seen what, exactly? The look of terror in the eyes of your guests as they realize that you really are a monster?

This time, the voice came from either side of his head, but when Damakoes glared at the pieces of his new costume, they were still looking straight ahead, just as he'd oriented them.

It had to be paranoia getting the better of him, and that was what he chose to believe, until he moved his paws to the neck of the rightmost head, feeling like it had slipped just a little out of place.

"The strap isn't on that tight," he grumbled. "Why the heck are you being so stubborn? Just move to the side already!"

His efforts were enough that he worried about damaging the neck of the costume piece, but mild panic was already setting in as he gripped the neck and squeezed it so tight, it would have been enough to choke a real, breathing beast.

That he felt a sudden dry spot in his throat had to be a coincidence, as far as he was concerned.

"Look, you're starting to chafe my shoulder a little bit. You need to f-friggin' move, dude!" he growled at the head, but his efforts continued to fall short of making a difference. Indents from his fingertips were left on the impressive, realistic flesh of the neck, and against his own, he felt the softest phantom pain, as if the other costume head was trying to reach over and imitate the act on him.

Fear emboldened his strength, and his jaw dropped as he pushed the head away from his shoulder, only to hear a gut-wrenching riiiiiip when the neck tore away from his flesh...and took some of his fur with it.

"I'm already as far to the side as I'm willing to go, Damakoes. To be honest, I'd prefer to be a little closer to the middle, but you called that spot a long time ago, didn't you?"

He was able to pretend that he didn't see the lips moving from the corners of his eyes, but when he was staring right at the artificially attached head, denial became a coping mechanism.

As his lower lip trembled, Damakoes released the second head, moving his quivering wrists back to his lap. He tried to control his breathing and center himself, but a tickle at his left ear was followed by the feel of something that started out like neoprene...only to become slick and fleshy as it moved down his ear lobe.

"He's the brains of the operation, no doubt," the left head spoke this time. Its words were followed by a small rush of warmth, rolling over Damakoes' cheek with a weight that went beyond the ethereal presence it should have commanded. "But that would make us the heart and soul, wouldn't it?"

"If it does, I've gotta say...I don't really approve of his heart being in this much pain."

"And I don't approve of this much confusion in his soul..."

Now that the voices were on the outside , Damakoes couldn't ignore them anymore, but he didn't know how to respond to them, either.

Acknowledging what they said wasn't going to stop them from whatever nefarious means they had planned, and just thinking about trying to pull the heads from his flesh again was making him a little bit squeamish.

"Perhaps a little bit of a makeover is all he needs? A change of the body can be a reflection of the heart, soul and mind working in unity..."

It was a rather heartwarming idea.

"Toward the goal of terrorizing those mortals who might still wander the streets tonight..."

And in an instant, it became a bone-chilling plot that Damakoes found himself incapable of fighting back against.

"Do you think a three headed beast would be enough to frighten those souls who've taken to the streets in search of a good scare, Damakoes?"

The leftmost head was already shaking. "No, that wouldn't be nearly enough...what kind of creature has three heads, but only two arms? We need more than that!"

In the middle, Damakoes was already feeling overwhelmed by the unusual changes going on around him, but more than that, he could feel the influence of the other two heads weaseling their way into the back of his mind once more, as if they knew he'd resist their plans.

As they'd already grown into his body, however, they were already getting an inkling of the best way to keep him on board with their ideas, and they didn't mind taking a small detour to make sure that he'd play along.

"What do..."

His lips were dry, his throat was a desert, and his whole body was shaky with the reality of what was already happening to him; the possibility of what came next kept him trembling.

"What do y-you two need f-from me?"

Around the middle head, the other two shared a knowing grin.

"You simply need to relax and enjoy yourself," the rightmost head answered. "I think a good place to start would be stripping out of that silly loincloth...what kind of Cerberus ever wore clothing in the first place?"

Damakoes didn't leave much to the imagination when he picked the outfit in the first place, but calling the covering on his lower half a loincloth was underselling it a bit: what he wore was closer to a full skirt, complete with boxers underneath, as if he were actually expecting to behave himself around company.

The quivering in his arms came to an immediate stop, and determined fingertips flew to the waistline of his outfit.

"That's the way," the leftmost head whispered to him. "No one of your stature should be forced to display shame...especially when you've got so much to offer the world around you!"

Corrupting influence followed their every word, crawling up the lobes of his ears and right into his skull.

"You know, we should really be balanced in all ways, shouldn't we?"

This time, Damakoes was speaking back to his extra heads, and as his garments hit the floor and exposed the warm fuzz upon his sheath, he could feel new flesh coming to life just above and below his arms.

"You're in no position to be making demands, are you?" the rightmost head asked.

"Maybe I'm not," Damakoes admitted. "But if you each get an extra set of arms, is asking for an extra one of these so bad?"

His resistance was crumbling little by little, until he was a willing vector for whatever his new heads were up for, that evening.

If that was the only request he made of them, he was making their jobs a little too easy; they were more than happy to run with his idea if it kept him compliant, and the rest of his body was up for grabs as their existence became further intertwined with his own.

"Hardly need a second when you're already packing that much heat down there, but I suppose we are in the mood to scare people. No reason we can't frighten them with every aspect of your body, is there?"

Aside his sheath, another passage was already starting to grow. From the original, the black and blue spackling of his unique member was starting to emerge, but even seeing the tip of it, Damakoes could tell that it was a little larger than it had been before.

He knew he had the cursed costume to thank for his new, rapid growth, but he wanted to see what the final outcome would be before he offered his new roommates any words of praise.

"Damn right there isn't," the rightmost head answered. "And you're gonna need to test that new equipment out here at home before you go trying it on anyone else, Damakoes. You'd better give that first cock a stroke...make the second one a little bit more eager to come out of hiding."

It was clear where the dominance in his collective heads now rested, and Damakoes was still so stricken with whiplash from the whole thing that he wasn't making an effort to get involved in the conversation.

He was simply following instructions when he grasped the base of his first length and held it with a firm, commanding grip. Stroking toward the tip and simulating a milking action on his own flesh, he moved his arm in accordance with what the other heads wanted, and all the while, the leftmost head simply watched the action, nearly drooling at the sight of what it was getting to enjoy.

Judging by the hint of nerves in its stare, it wasn't always_allowed_ to savor the experience.

"See that? Look at how much bigger you've already gotten...and how much better it feels when you've got someone else pulling the strings for you," the rightmost head continued its campaign to keep control of the hybrid, thinking that it might have found the perfect angle to play. "And just like that, we've already got a second tool in the mix..."

Granting a pleasure that no one else could was an easy way to work your way inside of a person's mind, but Damakoes wasn't being won over as easily as it seemed.

He was still clinging to whatever little fibers of consciousness remained as his other paw came to rest on his second member, holding it with a warm and tender grasp; he simply needed to feel that it was real, and knowing the reality of his new flesh, he was more than happy to jerk both of his cocks at the same time, wondering how quickly he could bring himself to his own knees.

"Shouldn't we...I mean...m-maybe we should focus on the arms?" the leftmost head chimed in, though his eyes were locked on the sight of a pair of rods that continued to grow, appearing just a hint longer each time Damakoes stroked them. "Those are great , but I don't everyone is going to be intimidated by what he's packing down below."

Corruption was still the goal of the first head to awaken, and it scoffed at the idea of worrying about the rest of the transformation. "You want to waste your time with beefing him up? Be my guest...but this part will be my department."

Worried that his craftier thoughts might give away that he wasn't as hypnotized as they thought, Damakoes played along and nodded his original head somewhat absently, hoping to sell the lie just a little bit longer.

He hadn't anticipated just how much pleasure he'd feel from sprouting a second cock, but the bliss of stroking them in tandem was such that he didn't have to worry about his words betraying him: he couldn't imagine making a sound beyond the long, continuous stream of gasps that poured over his lips.

"You know, more paws would mean more pleasure," the leftmost head pointed out. Though it was tough for him to break his focus from the trickling streams of precum that spilled to the floor, he had another job to do if they were going to convince anyone that Damakoes was a real Cerberus, and the small lumps of flesh that formed above and below his shoulder blades were still a few steps from being the extra arms they needed. "Just something to keep in mind..."

"Make them happen, then," the rightmost head countered. "I need to make sure he doesn't let up before he reaches climax...I want to see him paint the floor with his cum."

"Shouldn't he save it for someone else?"

"He should do whatever I say with it," the argument continued, until it was becoming difficult for Damakoes to stay on the proverbial sideline. "And right now, there's no one else here to make a mess of it with...so it's either on the floor, or on him. Understood?"

For a moment, Damakoes was worried that he didn't have a choice in where his seed ended up, but as he watched his paws moving back and forth over his tool, he couldn't keep a tiny grin from tugging at the corner of his muzzle.

The other two heads were so busy going back and forth at each other, they didn't even notice that they'd given the hybrid most of the control of his body back to him; if he didn't draw any attention to that fact, he'd be able to take advantage of the situation all he wanted...and he didn't see a need to change anything, right then.

With the new arms coming in nicely and squirming to life behind him, he was getting some ideas about how he could add a new twist to the act, and his new heads wouldn't be any wiser to the fact that he was enjoying himself so much.

"Y...yes, understood," the leftmost head conceded, doing whatever it could to avoid the ire of his original companion. "It looks like he's...g-gonna make an awfully big mess already, isn't he?"

"Just as we planned," a sinister whisper spurred Damakoes into further corruption, but this time, the dragon-wolf was anticipating those words and playing along: the clench of four new paws around the fully erect lengths brought him pleasure like he'd never known before, prompting him to stroke with a slower touch.

He wanted to enjoy the unique experience for as long as he could, but there was only so much he could do when faced with such an onslaught of bliss.

"You can't resist it anymore, can you?" the rightmost head taunted him. "You can't handle what we're forcing you to do...you have to cum, don't you?"

The grin was too much to hide any longer, but Damakoes no longer cared about being caught. Fangs caught the glimmer of the moonlight coming through the living room windows, paws rushed back and forth over his twin cocks, and all three heads shared an expression of deep, earthly pleasure as the weight of orgasm came crashing down on them.

"I could probably last a little longer," he admitted, "But...there's so many other things I could be doing with all these extra limbs...I'd hate to be so selfish as to keep this secret to myself!"

His exclamation was followed by a long, thick hail of cum from both of his tips, sending a streak across the floor and leaving a mess in front of him that he'd worry about cleaning up later.

In that moment, he was too busy being blown away by the sheer ecstasy that grasped his entire bodice, flooding into his guts from the pair of cocks he'd been blessed with. The shock went far beyond an ordinary, full-body orgasm, bringing him to his knees and leaving his fur tarnished with the warm, thick stains of what he'd just done...but there was no shame in wearing that mess.

It only added to the wild appeal that he'd been given, and muscles that rippled with every clench of his climactic experience made him a proper beast...the kind of thing that would be frightening to see in the neighborhood at first glance, but for those brave enough to take a second look, the delights that would be had were untold and numerous.

"And just who do you think you are to go making plans like that?" the rightmost head demanded. "Who do you think is in control here?"

Damakoes didn't even give the leftmost head a chance to make a weak excuse.

" I'm in control, and if I say that we are going out to have a little fun tonight, you two don't have much of a choice in the matter, do you?"

They were only supposed to be pieces of the costume, but in their determination to build a better monster, they'd become part of one; the brains of the operation might have been satisfied with his new form, but just as it was when the night started, he was determined to show his costume off...and anyone would make a better audience than an empty living room.

"You know we're way too old to be out and about on Halloween, right? Like...we're not walking to a party or anything. That means people are gonna look at us funny."

Ben and Phillip weren't the kind of couple to let societal judgment bother them, but the latter was still a bit timid about the concept of trick-or-treating, especially when they were well into their adult years.

The former, however, wasn't too worried about their decision to put on costumes and wander the neighborhood, desperate as they were for social interaction.

"Have you seen anyone else out tonight? You're way too worried about this," Ben murmured. He gave his boyfriend a nudge and hoped to bring a smile back to the dalmatian's face, but his second nudge missed the target.

Phillip was stopped dead in his tracks, staring up at the creature that blocked the guiding light from the streetlamp above them.

"You two are a little old to be out looking for treats, but if you take a few more steps to the corner, you'll be in just the right spot to turn a few tricks...and you're certainly dressed for the part."

Chains rattled as the Cerberus lifted his multiple arms, and all three heads glared down at the pair of canines, thinking they'd be the perfect audience to appreciation his new, larger body.

Towering over them, draped in the menacing chill of moonlight, the transformed hybrid was scary enough to be the stuff of nightmares...but he'd dawned on just the right couple to make good use of his improvements.

"One cock for each of us, Phillip? Or do you still think we're too old to be out on Halloween?"

The Dalmatian didn't have a quip prepared for his boyfriend.

He was too busy drooling to come up with a reply...
