Super-Spreader

Zachary grinned as he looked down at the almost peaceful looking cub, his own rod resting on his grandchild's belly, still leaking thick cum from the tip as Matt's chest slowly rose up and down. Almost before his eyes, he could see the cub transforming, the infection quickly going to work and changing the young fox's body to make him more suitable for attracting more potential victims. The boy grew an inch or two, both in height overall as well as the size of his cock, his muscles gaining more definition. Zachary caught a glimpse of himself through a reflection on a window, noting that he himself had also continued changing, seeming even younger than when he had arrived home, smirking at his new image. Not wanting to waste too much time on admiring his more toned form however, the old canine grabbed up the kid's limp body, carrying Matt upstairs and tucking the kit under the covers, just in case someone happened to come in before the boy had regained consciousness. His next step was to get rid of his wife for the time being, not wanting her to be an obstacle for the activities he had planned for the sleepover. He picked up the phone and dialed her up, hearing her chipper sound on the other end, 
"Is that you honey? I'm sorry I'm not home yet, it's dragging on a while longer here than I would've thought, I'm hoping to maybe catch the six o'clock train back."
"Oh, it's alright. I'm actually calling that maybe you should stay with your friend for a while longer, stay the night there, maybe even two?" 
"Stay here? What for?" 
"Well, Matt's got a bit of a sniffle, he's down pretty bad and I think I can already feel my own throat going as well. I don't see much point in you catching the flu as well, might as well stay there and enjoy the company of your friend some more, especially since you get to see her so rarely."
"Oh… I was really looking forward to getting to spend some time with Matt…" 
"So was I, unfortunately neither of us is going to be very good company while lying in the bottom of a bed with a sore head. I'm sure we'll get better soon enough, best for you to stay there until then."
"Well, I think I could talk her into that. See you in a day or two then sweetie, I'll call you tomorrow to see how you're both feeling."
"You do that, I'll talk to you soon."

Matt groaned and rolled over, a piercing ache suddenly shooting through his skull and making the kit grasp his head, whining as he curled up into a ball, the pain slowly subsiding over the course of a few seconds until it was only a dull, thudding burn. He relaxed his body and rolled over onto his back, the muscles all over his body feeling like he'd gone through the worst cramp in his life, the pain only lasting for a few more minutes until it suddenly all went away, a whole new feeling of bliss and pleasure covering him. He threw his blanket off and sat up, noticing that he was completely naked, his asscrack still moist from the creampie his grandpa had given him, the large load slowly trickling out from his tailhole one drop at a time. He stood up and took a long breath, feeling very peculiar, both physically and mentally. The boy didn't have much knowledge about adult stuff, but he assumed he should have been feeling much more violated than he actually did, his mind surprisingly calm even after being molested by his grandfather. He looked down at his body, noticing the changes he had been given, a new sensation of a foreign need slowly waking up deep in the pit of his belly just as he heard someone walking up the stairs, Zachary opening up the door to the guest bedroom with a grin, 
"Good, you're awake. You've got the gift now, how does it feel? it's telling you to do something, isn't it?" 
Matt tried to get his brain straight, still slightly unsure and confused about everything that had happened as well as what his own head was telling him, eventually relenting with a small nod, the older fox continuing, 
"Obey it, do as it tells you. You can't fight it, but it'll feel really good when you do what it says. It wants your friends, all of them, and we're gonna give them to it tonight~" 
The thought of doing to his friends what Zachary had done to him made the cub smirk, something deep in his subconscious telling him that the act was exactly what he should be trying to accomplish. 

The two males spent the next few hours getting prepared for the arrival of their guests, the older fox wiping away at least the most noticeable of the odd white stains and globs from the sofa while Matt prepared a very special batch of chocolate milk in the kitchen. He poured the milk into a large jug, setting it on the ground and kneeling in front of it, his cock already hard as he grabbed hold of his knot, kneading it as heavy drops of his thick precum dripped down into the drink. Zachary soon joined him, standing next to him with one hand resting on the boy's shoulder, the man's other hand pumping his shaft as he panted. Matt was still getting used to all of the new feelings and experiences that the virus had introduced to him, having never jacked off before and only having cum once previously, when he was converted. His head slumped down and his lips quivered as he dipped his tip into the milk, grunting as he orgasmed, large ropes and wisps of cum floating onto the surface as he unloaded everything he had to give, his body having been changed to make sure he'd be able to shoot enormous amounts of seed. Zachary chuckled at the cub, petting the boy on the head as he humped against his hand, giving one last thrust before aiming his canine dick at the jug and releasing, his cum splattering half into the chocolate milk and half all over the sides of the container. With the milk properly prepped for the sleepover, Matt smiled and grabbed the jug, mixing up the liquid inside before setting it inside of the fridge to wait for the right time. As one last step, the two foxes got dressed back up, knowing that the pair being butt naked while the friends were arriving would have caused some commotion. With everything prepared, the canines planned out how they would approach the evening, dividing the soon arriving cubs amongst each other. 

As the hours went by, Matt's friends finally began arriving, being dropped off by their parents one by one at the house, both of the foxes waiting at the door to greet them. The first one to arrive was Cooper, the youngest of the whole group, a small, 8 year old sparrow, a tiny spot of white peeking through the top of his shirt while the rest of his feathers were brown. Only a few minutes later, Elliot was dropped off, the 10 year old tabby cat waving happily at the canines waiting for him. Soon after, Wes and Noah arrived together, the equine siblings walking side by side. Wes was 11 years old, a few years older than his younger brother, his grey coat dotted with the occasional blotch of white while the other horse was entirely jet black. With all of the cubs there, Matt brought the group into the living room, the coffee table set with all sorts of snacks, a big jug of chocolate milk sitting right in the middle. Zachary sat back and let the night start off without any interruptions, the kids watching a movie on the TV while enjoying the offerings, his sharp eyes scanning the friends from the sidelines, his cock throbbing in his pants. About an hour later, he noticed that the feline was seeming slightly drowsy, his grandson having noticed it as well. Matt glanced at the man, getting a nod before springing into action, the boy leaning up to Elliot and whispering, 
"Hey, can you come to the backyard, I've got something to show you." 
The cat nodded and the pair stood up, leaving through the backdoor as the other cubs glanced at the pair, slightly curious but not nosy enough to follow them. Matt dragged the friend along until they were well out of sight of any of the living room windows, getting the boy behind a small shed. Elliot looked at him inquisitively, expecting to be told why he needed the tabby outside, the fox instead pushing his lips against the cat's and grabbing on tightly. The feline moaned in surprise and struggled to get out of the tight embrace, his protests muffled by the tongue that had invaded his maw, his muscles feeling more and more weak with every passing second. Matt pulled back from the kiss and let go, Elliot dropping onto his knees, the infection beginning to work on him both due to drinking the spiked drink as well as due to the canine's saliva, unable to think straight as Matt grinned, 
"Just relax and don't fight it~" 
The kit pulled down his pants and grabbed onto the cat's head, shoving his cock into the other boy's mouth, starting to hump the tabby's muzzle. Elliot tried weakly to push his friend away, choking and coughing as the red rocket dredged his throat, whimpering as suddenly a burst of cum filled up his maw. Sperm shot out from his nose and dribbled down his chin as the fox moaned, the salty goop forcing its way down his throat as he swallowed, Matt pulling out of his muzzle and letting go of him. He flopped backwards, landing on his back as he began shaking and groaning, cum still leaking out from the corners of his mouth as the canine grinned and pulled his pants back up. 

Zachary glanced through one of the windows towards the backyard, grinning as he spotted the other fox stumbling out from behind the shed, seemingly quite satisfied. It was now his time to strike, the man noticing his prey nearly dozing off before strolling up to the sofa and gently tapping the younger of the two horses on the shoulder, squatting down to get on Noah's level, 
"Hey, your dad just called, there's apparently something you needed to sort out with him, something about your computer." 
The cub glanced at his brother, confused, before shrugging and hopping off of the sofa, following behind Zachary as the two walked to the other side of the house, the canine closing the door behind the duo as they stepped into a small room that had been converted into a cozy little study. Still lightheaded and dizzy, Noah looked around, seeing no phones of any sort around, 
"Uhh… wh… where's the ph-" 
He was cut off as Zachary grabbed onto him and shoved him down against a chair near the corner of the room, coming up behind him and wrapping a hand around his muzzle to stop him from making too much noise, 
"Shh… just relax, you'll thank me once I'm done with you~" 
The man heard some footsteps coming close, getting ready to make up an excuse when suddenly the door opened, Matt peeking inside, 
"I did the thing with Noah, stashed him in the shed to let him sleep for a few hours."
"Good, wanna help me give this boy the gift as well~?" 
"Yeah!"
"Well then, you can take the backside, I'll take the maw~" 
Zachary slung the horse towards his grandson, the boy grabbing onto the disoriented cub as he sat down, quickly undoing his belt and flopping out his cock, motioning for the pair to come forwards. Matt pushed Noah on his knees, stuffing his face between the grandpa's thighs before yanking his shorts down just enough to expose his tailhole, the kit shaking with anticipation as he squatted down behind his friend, noticing the equine shaft spring to life. Both of the canines entered the dark stallion at the same time, Noah suddenly finding both his muzzle as well as his ass stuffed to the brim, able only to weakly moan and huff as Zachary grabbed onto his ears to pull him further down the shaft in his mouth, his tongue slabbering the thick knot almost on its own. Simultaneously, the eager cub behind him was drilling his flank, the fox's crotch bouncing off of his ass cheeks as the force of the thrusts forced him to swallow more of the grey muzzle's dick. Zachary was the first one to cum, Matt following close behind, the equine's cheeks bulging out as a sudden torrent of sperm filled his mouth, stopping him from yelling as he was knotted from the back, feeling the cum flowing into him from both ends. The surge triggered something inside of him, the erection he had been nursing suddenly going even harder, his tip flaring out as he exploded into his underwear, his seed dripping down his legs as he started to lose consciousness, his eyes rolling back as his muscles began spasming. 

Matt popped his knot out of the horse's tailhole, his yellow tinted cum spewing out and down the black flank, his erection still strong as Zachary gently set the unconscious Noah down onto the ground, 
"He'll get to experience the joy soon enough~"
The two foxes smirked as they pulled their pants back up and rejoined the other two cubs still relaxing in the living room, Zachary's eyes fixated on the young bird. The boys were sufficiently influenced by the spiked drink that he could simply grab onto Cooper's shoulder, leading the staggering kid upstairs and into his bedroom, tossing the sparrow onto the bed. The avian landed on his belly, his eyes half closed as he stared ahead, only half aware of what was even going on. He felt the man undressing his lower half, looking back to see Zachary's cock pointing up towards the ceiling as the fox massaged his ass cheeks with a hungry look, kneeling down and spreading his ass open. Cooper pushed his face against the mattress, moaning into the soft bedding as he experienced being eaten out for the first time, his small shaft quivering and gushing with precum as the old man rimmed him. Zachary had his muzzle stuffed between the little boy's buns, greedily licking at the tight hole, his tongue running over the bird's taint and ballsack before slithering inside of the tailhole, his nose buried in the cub's tailfeathers. After a few minutes of rimming, the compulsion in him grew even louder, his mind ordering him to stop with the foreplay and to just get the conversion done already, his shaft pulsing with anticipation. He pulled his maw out from the boy's backside and stood up, nuzzling his tip against the slick asshole, one hand rubbing and petting the bird's back as he took a breath and pushed inside, his girth slowly gaping Cooper open. The sparrow squealed and buried his beak under his hands, his legs trembling as the hard shaft in him pressed against his prostate, his mind almost completely blank and unfocused. After sufficiently stretching out the cub, Zachary grabbed onto his latest victim and pulled back, growling under his breath as he bucked hard, slamming all but his knot inside. He fucked the tight hole as hard as he could, right where him and his wife had happily slept together not even half a day ago, a smirk on his muzzle as he lightly yanked on the plumage on the avian's head, pulling Cooper's upper half off the bed. Watching the boy's dazed face, he plunged his knot inside, the young male whimpering quietly as he moaned and unleashed his load, filling the bird's ass with his viral seed. 

Noah woke up, rubbing his head, finding himself propped up on a chair with most of his chin and lower half covered in cum, odd and muddled thoughts floating around in his head, one in particular a thought that he simply couldn't shake off no matter how much he tried: he absolutely had to sleep with his own brother. He had never had notions like that before, not even a passing interest in other males, but now he for some reason could do nothing except lust after guys, the thought of females suddenly seeming repulsive to him. The stallion pulled himself up and shambled into the living room, his pants still hanging open from the front, his brother the only one sitting in front of the TV, half asleep. Noah cuddled up next to his older sibling, moaning gently as he snaked his hands down to Wes' fly, zipping it open and feeling up the bulge that was already forming, 
"I'm gonna make you feel so good~!" 
The cub threw his own coverings off, getting completely naked before pulling the other equine's pants down, the mottled horse's cock half hard as he stroked both himself and his brother at the same time. Wes was only barely aware of what was going on through the haze, grunting and gritting his teeth as the younger boy jerked him off, his heavy balls resting against his legs as his tip began flaring up. Noah grinned and spit into his hand, coating his brother's shaft with his saliva before standing up on the sofa, lining his tailhole up with Wes' tip. He sat down on the rod, feeling it slide up into his asshole, moaning and shaking in pleasure as he threw himself against his sibling's chest and jacked himself off, panting and quivering as he rode the girthy equine dick. He could see his own belly bulging out whenever he shoved the shaft balls deep into himself, the male under himself puffing and muttering something incoherent. Suddenly, a rush of warmth flooded into his bowels, his whole body tensing up as he realised that his own brother just shot a load deep inside of him, needing every drop of self control to not orgasm right then and there as well. He quickly stood up spun around, Wes' cock still throbbing and shooting heavy ropes of sperm all over both of the boys as well as the couch, Noah quickly opening up the other stallion's maw before shoving his length inside, finally letting go and whimpering out loud from the absolute bliss, his seed dribbling down his sibling's muzzle. 

One by one, all of the converted cubs woke up, their bodies slowly but surely changing from the virus, the two foxes gathering them all up back into the living room and watching with satisfaction as they all sat there, naked and erect. Zachary scanned his eyes over the row of boys, slowly stroking himself as he huffed, his mind finally at ease, at least for the moment. He knew that he'd get another target soon enough, when whatever it was that was in his body decided that a male would be a good vector for further infection, but at least for tonight he'd get to simply enjoy the spoils of his hunt, wanting to make absolutely sure that the kids were all sufficiently and thoroughly infected. His grandson was already kneeling down in front of the bird and the younger of the two horses, masturbating and sucking them off, Cooper chirping happily while thick and yellow tinged precum oozed from the fox's muzzle. Zachary let his eyes wander down the other equine's flank, Wes noticing the interest and turning around with a sly smirk, flicking his long tail aside as he bent over with one leg up on the sofa, showing off his pucker. Happy to accept the invitation, the old man moved behind the stallion, grabbing onto his waist and squaring up with his hips, the boy moaning quietly as his asshole stretched open. Just as Zachary had entered the cub, Elliot quickly pounced on the fox, the kitten coming up from behind and wrapping his arms around the male, squeezing his shaft between the canine's cheeks. Chuckling at being stuck between two boys, the grey muzzle bent forwards to give the feline a better angle at his hole before thrusting forwards, driving his shaft deep into the stallion. The whole group of six males grunted and moaned in unison, letting free all of the excess sexual tension and energy that had built up in their bodies, letting their instincts lead as the evening went on and the moon appeared in the night sky. Zachary wedged his knot into Wes' tailhole and blew his load in the boy just as Elliot sank balls deep inside of him, the trio all embraced tightly as they orgasmed. 

At almost five in the morning, the last of the young kids finally slumped down and fell asleep, leaving Zachary as the final male still awake, the rest laying together in one big pile on the sofa. Everyone was completely soaked through with seed, both theirs as well as everyone else's, their furs thoroughly stained with the same yellow tint as their cum. The fox leaned his head down against the backrest of the sofa as he exhaled hard, relaxing his body and closing his eyes. Even after several hours of nonstop humping and breeding, after tens and tens of orgasms and what must've been gallons of cum that had left his balls, he still felt horny, his cock still standing at half mast even as he felt his mind slowly drifting off to sleep. The sex felt great, amazing even, but he had realised that the only true satisfaction and relief that he'd feel would be after a conversion, after passing on the gift that the neighbour's boy had given him. Nothing else would bring about that feeling of respite, the rest of the time he'd be stuck with trying to chase after that high, like a wild animal locked in a cage right next to a bitch in heat. Even still, he wouldn't give up the gift even if he could, that feeling of satisfaction after a successful conversion making up for all of the trouble and stress. As he laid his head down next to his grandson's and let his mind rest, he felt his subconscious ordering him to chase down another male, knowing that tomorrow would be equally as busy.
