C.H.R.I.S.T.M.A.S. With Additional CM

Peter was enraged.

His older brother refused to do his part of the chore again and he was forced to do it, or else faced the wrath of their mom.

Alone.

It was unfair.

But what was he going to do but to grit his teeth and bear it? He's just a silly, underaverage-in-every-sense teenager who couldn't face the world alone all by himself.

Wait till he was eighteen and he'd fly away from this mouse hole; just like what his father did five years ago.

Thinking about his father irated Peter further and he practically threw the garbage he had been carrying onto the ground. Wet splosh sound of questionable content rang as the filthy bag hit the dirty snow that had covered the even filthier ground at the back of their hom--

House.

He refused to call this torturous building a home he'd return to at the end of the day. He hated this house. He hated his family. He hated his life.

This was a frigging Christmas and he can't even enjoy the tiniest glint of it!

His mom was out at work at some greedy, money-hungry place he didn't bother remembering anymore, as she switched her jobs quicker than a blink of an eye. His brother decided to be a jerk, as usual, and stayed at hom-- house, to squeeze any happy moment out of his system. His friends? Hell, like he HAD any friend.

Peter turned around only to stop midtracked. In the dimly lidded small backyard, something caught his eye; something that seemed strangely out of place and very noticable to him rested on the snowbed close to the far end metallic fence. He examined it with his gaze as he walked closer to it. Its shape was tubular. The length must be around a foot or more and the widest part was about four inch wide. As he approached it, it became clearer and clearer for him to determine what the mysterious object was.

A dildo.

A BIG one, too.

He loved that.

Yes, he was gay. Rather submissive and always love big dicks. If it came with bigass muscled body then it was pure heaven.

Just don't ask him how he managed to hide this fact from the other family members.

Peter smiled lewdly and picked the sex toy up to see up close. It turned out that the deep red thingy was not human's in shape. The endtip was tapered and there was no usual mushroom head there. Near the base was a large bulbous portion that looked a little too large for his anus to handle without any injuries. It was certainly quite weird for him.

But a little experiment wouldn't hurt. This was Christmas after all, so he could pretend this was the present that he had been waiting for.

A toy in hand, Peter waddled back into the kitchen with a somewhat cheerful face. He and his brother had dinner a moment ago. Not a ceremonial, marvelous one for the holiday, mind you. Just some microwaved pizza that HE had prepared. And what did his brother do? Watching TV in the living room like he owned the place, walking into the kitchen when the microwave dinged, plummaging through more than half of it, and going straight back to the royal throne of entertainment.

Agh, his brother was in the house! Happy face switched off. Grumpy face switched on. All set. Onward!

Peter advanced out of the kitchen, trying to be as 'normal' as possible: indifferent, uncooperative, and super-negative. He did not forget to hide the item of happiness from his ever curious brother's line of sight as he walked across the living room and up the stairs to his little sanctuary.

Good. His brother didn't seem to care about him much.

Peter reached his tiny room and closed it shut, trying not to slam it out of excitement over a new toy and risked calling for his brother's attention. He threw the toy onto the top of his bed and duck low to fished something from underneath his bed. Unbeknowst to him, the base of the red dildo shone bright green for a brief moment, but when he rose up again with lube, the glow had already stopped.

Peter did not waste anytime and lubricated the inhuman dildo with excesstive amount of lube. If anything he knew that the faster he get it done, the less chance he'd get caught in the action. And another was that more lube equaled less pain and resulted in a smoother session.

Yes, that'd mean he's depriving himself from enjoying it fully. But if he'd get to have a roof over his head then he will definitely

Grit and bear.

Finished with the toy, he ridded himself of his jeans and boxers, and then went to lube up his ass with his fingers, pushing it in one by one. His cock stirred slightly as blood began pumping into them. He closed his eyes and enjoyed the stimulation.

During his preparation, the dildo started to glow again, faintly and unnoticable. Millions of symbols so small that human's eyes couldn't distinguish one from another flashed green starting from the base and ran up the tubular object halfway and stopped.

Green light pierced his eyes for a moment and Peter frantically looked around for the source. Did something happen? Did he get caught? But the moment he acknowledged the light, it had already gone. Seeing nothing and not wanting to waste any more time, he continued his work until the hole was slick and prepared for the sheer girth of his new toy.

Peter grasped the dildo and lay down on his bed, face up. His cock bounced slightly upward in anticipation as he positioned the tip of joystick at his rump. He prodded it with a little pushed, teasing himself and getting mentally ready for it. Steadily, he pushed it in at the slow enough pace that he would get used to the size and fast enough pace that it would ensure a quick orgasm.

The green light came into his vision again, but this time it did not disappear when he noticed it. But, somehow, he did not bother looking up for the source and going at it still. He felt the intruding object inside his bowel grew larger, but shrugged it off as being his imagination.

Still, bigger equals better, so, no qualms from him.

The truth was, the now green-litted dildo was indeed getting bigger. As lines of runes fully adorn the shaft, it began its primary function of fulfilling its user's desire. From the surface, what the device could fish out of the current user's mind was 'pleasure' and all the fetishes that Peter himself did not know he had. With the information given, the dildo decided on a course of action and continued to grow uncontrollably, streching his orifice abnormally wide.

If this was any ordinary dildo then he would have cry in pain right now.

But in the lust-laden mind of Peter's, he was feeling intense pleasure like he never had before. He couldn't believe how wonderful a toy it was. He was just halfway through insertion; his prostate barely touched at all and it felt like he was on the brink of orgasm, even though his cock was not fully hard yet.

A llittle more push and he suddenly reached his peak for the first time this night. Waves of pure pleasure washed over him.

But the ejaculation didn't come.

He was orgasming but he didn't cum!

Confused and sexually high as he was, it did not occur to him that the dildo had been making its way in further and further until it's lodged deep to the start of the bulbous portion, which was now as wide as its starting length when he had found it.

When his sphincter spread out to the curve, Peter stifled a moan as another dry orgasm racked his entire being again. Jolts after jolts of euphoric sensation bolted through his nervous system, spanned out from his rump and gathered at his crotch, building up pressure at the base of his manhood. The dildo moved on its own accord smoothly and soon almost all of the dildo sunk into his bowel, left only the very base to be seen.

The magical device activated another command. His belly glowed green in a vague tubular shape and yet he didn't seem to mind much. He was too busy with afterglow that was cut short by the cumulative pressure that was suddenly became too much for him to bear and a loud scream escaped his mouth.

In that instant whatever trance that managed to grasp him broke, and immediately realized the mistake he had done. That was loud, too loud actually. His brother downstair could have heard that!

And he would come up to check what shenanigan he's up to!

He can't be caught! No!

Distraught, Peter sat up, unintentionally pushed what left of the toy all the way inside, eliciting a moan from the stimulation it provided and the pressure that had gathered. And when he glanced downward, he let out another scream, now of horror as his belly and chest was pressed out in a vague spearhead shape of the enlarged dildo, glowing sickening green. He tried to yank it out but, to his abhor, only made it dug deeper and stimulated him to no end.

Decided that the moment has come, the pressure that had been concentrating around his groin shot upward and thrusted into his member; the sensation not different from cumming, though as before, nothing came out. His dick twitched in tandem with the orgasmic waves times and times again. The pressure hardly dissipated even though it was being distributed into his sensitive organ.

Peter crossed his eyes, shouting, screaming, and thrashing about from the agonizing, torturing, and addictive pleasure.

The hell with getting caught. This was too good to pass!

All the while his proud member went from half-limp three to fully-hard four inch (underaverage, remember?) in one-sixtieth of a second. It didn't stop there as the hard prick bulged and twitched and jerked and grew and expanded. At first by millimeters, then centimeters, then inches, growing ever longer, stretching ever longer. As this happened, the protruding shape and color in his torso flattened, faded and became indistinguishable to the eyes. His manhood, in the other hand, pointed upward to the ceiling, past his nonexisting pecs and stopped an inch short to his chin.

Just an inch short! He didn't know what caused this but come on!

His girth was not to be messed with either. What should he compare this to? A tree trunk, yes that would work. It was magnificent, humongous as he like it.

Then another wave of pressure rushed into his sacks, causing it to hang lower and gaining more masses. His balls went from pathetic to golf balls, oranges, grapefruits, soccer balls, bowling balls as more pressure flushed into them and the accumulated amount starting to fade. It ended at the size of overgrown watermelons. He hadto shift in his stance a little to accommodate the size.

Now not only his cock, his balls were in a perfect proportion. The object of manliness was very tempting, and it occured to him that his proud item was not touched at all this night.

This would not do.

Peter reached his hand out to touch the heavily veined pillar of meat and got his reward with immense pleasure. Precum squirted out and he quivered just from that. He pulled out his hand and quickly replaced it with his embrace.

If that was immense, then this was INFINITE.

Precum JETTED out going upward into an arc and rained back down on his head. His tongue lashed out instinctively and licked at musky liquid. Salty and tangy and completely MANLY. It gave off a sense of power... Of domination... Of control. Everything that he had not in his life and always craved for.

The feeling of being in charge of his life for once; being the man of the house.

He had to get more of that scent.

Peter hugged it more tightly and stroked it up and down, squeezing more juice from it and bathed himself in slimy clear fluid. With more lubricration, his stroking become more frantic, fulled with determination. The feeling of his clothed arms against the skin was like heaven, and every time it rubbed the mushroom head his cumslit would reward him with more juice.

Then with a loud roar, he finally came. Shooting out streams of cum so strong that he lost control of his dong, and thrashed around wildly like an unhandled fire hose, sending white viscous fluid around the room. Walls, ceiling, furniture, everything were painted white and all the excessive liquid ran down to gather at the floor, creating a pool a few centimeter deep.

Strangely the door was not being targeted at all.

Peter saw this and aimed his now more docile weapon to the rectangular piece of wood and washed it through with the last shipping of this batch of seed.

What he did not take in mind was that his brother WAS coming to get him.

So, when his brother opened the door at the same time as he was blasting that last shot by chance, the older male immediately got doused from head to toe with the gooey substance. The shot was also forceful enough that he sent his hated sibling to the other side of the hallway. The victim was hit so hard, first from the blast, and second from being pressed into the wall, that he cried out, swallowing some of the stank goo in the process.

Peter was feeling greater than he had ever felt in years. Not only he just had the best orgasms ever, that manly scent of his was wafting EVERYWHERE. His room was a mess. There were some indentations in the wall where the first stream was directed at. The pool of cum flowed out to the hallway where his brother was left soaked white, sputtering some out of his mouth.

"Cough. Cough. What in the fuck wa--" His brother was cut short when he lifted his head and finally saw his younger sibling sitting on the edge of the bed, half naked with a gargantaun hardon that refused to go limb despite shooting gallons of cum just a moment ago.

That cock was HUGE, and that was an unacceptable understatement.

In the throe of lust and excitement, Peter failed to notice that the tip of his maleness was now at his eyes level and the diameter was just a few inch away from that of his torso. The balls hung so low that it touched the surface of the cum pool underneath his bed.

Peter looked at the soaked male and instantly on the brink of yet another orgasm. His brother, Billy, was coated entirely in HIS scent. He sniffed. Yes, his scent; no one else's. His and his alone.

Peter got up and marched toward the dumbstruck Billy, waddled through his own puddle, out of the room to grab him, and gave his brother a devious grin.

Billy shuddered at the contact at his shoulders and tried to squeeze away without any success. Peter was strangely strong... His scent was strong... So... Overwhelming... So good...

Billy mentally slapped himself for letting such a thought entered his mind. What was he thinking! This was the stupid Peter he was talking about. There's no way that this pathetic huma--

Now his thought was cut short when he saw the big tool glowed green. No, this was not humane at all! What... What is this alien thing before him!

Peter ignored the glowing radiance, and starting to lick at Billy's face, collecting his cum and replacing it with thick drool. Billy did not comply, however, and struggled against his grasp with all his might.

Disobedient... He won't accept it.

Without knowing it, Peter growled. Sending shiver to Billy's spine and only caused him to wiggle about harder. Peter growled louder, teeth showing through the curled up lips. Billy was afraid as shit now.

Seeing no compliance, Peter went to give this property of him a punishment. He opened his jaws wide, turned his head sideway and bit on Billy's throat hard, but not hard enough to draw any blood. Billy yelped in pain and continued to squirm, so Peter applied more pressure to it until Billy got the message and stayed still at last.

Upon reaching understanding, Peter released it and gave him another warning growl before he spoke authoritatively, "Strip off your cloth, Billy."

Billy alerted at the order, "Wha- What? No!", and suddenly regretted it as he was given another growl. "Wait! Ok! I'll do it. Don't bite me! Please."

Satisfied with the answer, Peter backed away to give room for his brother, while staying on toe if the older male decided to make a run. Billy saw this opportunity and was going to take it, when something in his mind told him not to and to do as he was ordered.

He was conflicted, that's for sure.

As the event unfolded, unseen alterations were being made to Peter's mind and body. One of them being the properties of his pheromone that was floating inside the house, and strongly concentrated on his seed and he himself. Every breath Billy took sent it pumping through his vein and going directly to his brain where it deciphered the signal and sent the appropriate reaction to his system.

Peter saw Billy hesitated for a moment, before he began putting off his shirt. Good. No more defiance. He got rid of his shirt himself and now standing naked before his brother, his gigantic cock glowing still.

Billy threw his shirt away and ran his eyes over the other's bare body as he went to work with his pants. Somehow it appealed to him more than pussies and boobies had ever done before. The glow on his cock now spread into his torso and Billy noticed the ripples on the skin wherever the green light went. He stared as the flesh ballooned outward and then contracted itself and formed firmed muscle, before it bulged outward again only to deflate back into even bigger muscle mass.

For Peter himself, he was feeling ecstatic. He felt power surging forward from his groin, up his torso and down his thighs, leaving them more powerful than they'd ever been, and going further. Soon he was sporting firm six packs abs and pecs, strong thighs and calves, enormous biceps and highly defined shoulders. And to Billy's changing mind, this was pure heaven.

Peter flexed a bicep, admiring it with his gaze. It was perfect for an important figure like him. He was to be admired by his subordinates after all.

The change did not stopped there as Peter felt itchy all over and went to scratch. What Billy, who had stopped everything altogether by now, saw was patches of white fur that sprouted here and there, growing larger, and despite its lushness, did not conceal any definition of muscle at all, and only help in accentuating every mounds and valleys better.

Now Peter was heavily muscled and fully covered in white luscious fur. Sensing no further changes on the way, he examined his new body and got used to it quickly before he grabbed his object of interest again.

Billy.

He shredded the remaining clothing on the man and barked out an order, "Down on all four," which he was glad to see it done in no time.

Billy did as was told and presented his rump to his alpha... Wait, did he thought 'alpha'? Peter was his a-- brother... No, this was wrong. He shouldn't do it, but he couldn't stop himself.

He couldn't.

His alpha was calling.

Peter sunk his face into that butt and took a whiff at his property. Earthy, quite promising, this would indeed prove to be a good recruitment to his... pack. Oh right, his pack. His face felt a little weird as he licked at the butthole, tasting the sphincter of his soon to be packmate and subordinate. Glowing green again, Peter's head transformed. Nose and mouth protruded forward forming a muzzle. Tongue lengthened in proportion. Teeth grew sharper and more vicious as his face took on a shape of a wolf. Eyes turned amber and ears tipped into triangle shape and moved upward to the top of his head, twitched to every sound being made.

Peter did not know what happened but he had never felt this alive before. The additional senses only made his cock drooled more precum as he tasted and smelled Billy. His tongue licked and left thin film of saliva at Billy's rump. Soft, wet, slurping sound as Peter became more adventurous and probed his slimy appendage into the other's bowel made Billy moaned in ecstasy. He flicked it around, touching along the surface and rubbing against his prostrate, making its owner's cock jerked violently.

Sensing that the lubrication was enough, he stood up. Billy groaned in protest but the look in his alpha's eyes when he turned around told him more than enough that this was just the beginning.

Billy bolted right up and followed Peter into his room. The impeding musk of his alpha stirred his cock into life. Peter was standing besides the cum soaked bed, and gestured the yet human onto it. Billy did not wait and hopped right on, lying on his back and splaying his legs wide, ready for his alpha to do with him as he saw fit. Peter grinned at the enthusiasm.

He stepped onto the bed; his weight making it creaked as its burden has never been this great before. Precum flowed freely from his hyperphallic organ like water from tap. In the back of his mind he wondered if Billy would be able to handle his girth, but something told him that it would be fine so he went with that.(

The tailless white wolf prodded the human with his mushroom tip, teasing the man a little. He would push in slowly so Billy could get used to it first before he moved on.

That was his intention.

But when he did it in reality, he just shoved it in halfway through without regard to the comfort of Billy at all. Blinding white invaded Billy's vision as the intrusion bring forth unimaginable pain and pleasure, mixed together into a perfect addictive blend. A bead of precum formed on top of his meager cock, already hard from the stimulation.

Peter slid his tree trunk of a prick out and let out a lustful growl. This hole was tight; he enjoyed the friction it provided so much. Too bad it would not stay tight by the end of this night. When Peter was fully out of Billy, he shoved back right in again, and deeper. Billy had to grit his teeth to accommodate the new girth. Its rounded mushroom head pressed out from inside his stomach.

Magic worked its way again when the entire body of Peter glowed bright green. In his blurry visage, Billy saw it concentrated into several green markings that adorn the white wolf from head to toe, giving him tribal looks. One marking was in a shape of ring at the base of his alpha's cock; its green light intensified as the others' faded.

Bolts of euphoric pressure shot up Peter's cock again.

He began humping at his subordinate, at first slowly and then escalated into a fucking frenzy as the pressure in his member grew. His balls were being tucked closer to him and mound of fur covered flesh erupted forth from the base of his pride and engulfed some part of it, pulling it close to his upper body, forming a sheath.

Unseen to both male, the manhood inside was being reshaped by invisible hands like it was made from clay. It lost its distinctive mushroom head and gained the tapered tip and a rocket shape of a canine instead. And as Peter was pounding faster and harder a knot began to form. It pushed itself from the sheath and was now teasing at Billy's ever more tender anus, poking deeper and deeper each time the alpha humped him.

Billy was over the cloud. He was being used by his alpha and he could not be any happier than to be in this spot. His eight inch hard prick was covered in clear precum and was on a verge of bursting many times. But he knew better than that. No cumming until he was permitted, so he suppressed it with all his willpower.

The pressure in his groin now moved to the back as another marking just above his ass crack glowed. Peter fucked Billy like a horny dog he was and in one forceful motion he was hilt deep into Billy, knotted to the very base. Peter howled then as he experienced the fiercest orgasm in his life, sending jets of cum directly into the man's stomach.

Billy was washed away in white again, as his alpha climaxed inside him. His belly swelled impossibly wide as gallons of seed was transferred into him. The knot that has been put in his rump prevented any escape. But with magic or not, his stomach has its limit, and soon the white musky gooey liquid surged out of Billy's mouth, making him drool waterfall of semen that pooled at his forming pecs -- the first sign of many changes to come.

Peter was spent, but not completely finished yet. As he climaxed the pressure in his rump shot backward, and now he had a white fluffy tail of a wolf, like the rest of his wolf-man body. With all the transformation done, the information that had been stored inside the magical device in the shape of a dildo poured into his brain. He didn't find a hard time to understand it all.

What Peter found was a device that can fulfill any wishes in the world, The Christmas miracle.

When he used it, it searched for the deepest desires of his heart and altered them to best suit him before it made them come true.

And what did he want the most this entire time?

A proper family. A loving, caring family that would share every happy moment with him and help support him in the time of trouble.

And now he had all the power to make that dream come true.

He couldn't be any happier than this.
