Spreading the Love

Zachary woke up in cold sweat, his head spinning like he had just stepped out of a washing machine, his pupils wide and his fur standing on end. The old fox slowly pushed himself off of the ground into a sitting position, groaning and mumbling as he rubbed his aching head, his whole body feeling sore like he'd been run over with a steamroller. One part in particular was especially sore however, the canine glancing down at his flank, a drop of thick and yellow tinted cum dripping from his tailhole, the memories of what had happened shortly before he had passed out rushing into his mind. He quickly staggered onto his knees, clumsily pulling his underwear and his pants up from his ankles, his cheeks blushing, desperately hoping that no one had noticed him lying behind some bushes in the nude with his asshole creampied. Zachary took a long breath before getting up onto his feet, his whole vision going blurry and unfocused as he stood up, his feet wobbling and shaking, the man stumbling from side to side before finally collapsing against a nearby tree, desperately holding onto the trunk with both hands to stop himself from falling head over heels back down onto the grass, almost puking from the nausea and the disorientation, his empty stomach being the only thing stopping him from heaving up onto the ground. He pressed his head against the tree and groaned, steadying his breath and closing his eyes, trying his best to let his body acclimate and ease up, his tail dangling limp between his legs. After a few minutes of simply breathing and staying still, the fox began feeling slightly better, his stomach no longer doing back flips with every passing second. He opened his eyes and carefully let go of the tree trunk, stepping back a few steps, his knees still on the brink of buckling but still managing to keep his body off the ground. He looked around the park, noticing that it had probably been about an hour or two that he had stayed unconscious based on the location of the sun, the cool breeze passing through the forest making him feel a bit better. He saw no signs of the young kangaroo that had caused it all to happen, his head still aching as he tried to remember everything that had occurred. He walked over to where he had been lying, a pool of cum still on the grass, the canine grimacing uncomfortably as he felt the backside of his underwear quickly soaking up the sperm leaking from his abused asshole. He stopped on his tracks as he noticed his glasses lying on the ground as well, suddenly realising that he wasn't wearing them even though he could see just fine. He picked them up, squinting at the pair in confusion, his eyes somehow having been completely fixed up to perfect 20-20 vision. He also felt that his clothes were somewhat loose, looking down to see that his pants and his shirt were somehow slightly bigger than what he remembered them being. He rummaged through his pockets to find the keys to his car, turning around and starting to shamble in the direction of the parking lot, his ears ringing and his throat dry. 

Zachary stumbled over to his car after a good handful of minutes of walking through the park, finally slumping up against the roof of it, panting and huffing, his head feeling as if he was about to pass out once again. On the way to the car he had spotted several other couples in the midst of the same thing he had just gone through, cubs laying right in the middle of the field with their friends or family railing them, the infected people not even seeming to care as they moaned and squirmed in public, the whole world seeming like a blur or a dream to the canine. He grabbed the side mirror and angled it to look at himself, his jaw dropping as he spotted the man staring back at him from the reflection. He had completely changed, looking like he was nearing his forties instead of being in his sixties, his fur having regained almost all of its colour that had been lost and dulled with age. He had grown a few inches in length, and instead of a slight beer gut he was sporting muscles like in his prime youth, abs peeking out from the neckline of his shirt. He stood and stared at his new body in absolute disbelief, frozen in place for almost a minute straight with his maw open until he finally shook his head and opened up the car door, sitting inside. He confirmed that he wasn't just seeing things, looking at himself through the rear view mirror as well, eventually coming to grips with his new, much more youthful look. He assumed that this was Adrian's doing, or more specifically the work of the "gift" that the kangaroo wanted to give him, the fox rewinding his memories back to all of the news he had heard and read of the odd STD that had begun spreading throughout the country. He could never have imagined just how incredible the effects of the infection would be, baffled as to how or why it would have this sort of an effect on people. He thought back to first seeing the neighbour's kid earlier on that day, remembering just how much better Adrian had looked, having suddenly gained muscles and grown in height just like he had, everything finally clicking into place. He sighed and started his car, trying to think of what he should do next, his first thought being that of immediately going over to a hospital to get checked out. Just as he was about to back out of the parking lot however, his head felt as if it was about to explode from pressure, the canine collapsing onto the steering wheel and groaning in pain for a few seconds before all of the physical agony suddenly disappeared. In its place was something new however, a primal desire like thirst or hunger, except that this need was for much more than just nutrition, his whole mind suddenly focused on his grandson. 

As if a chorus of voices was simultaneously both yelling and whispering into his ears, Zachary felt compelled to lust after Matt, unable to purge the image of the young kit spread eagle and waiting for him on a bed, a bulge forming on the front of his pants. He groaned and gripped his head, desperately trying to steer his affection back towards his own wife of several decades, trying to affirm that he was not gay and that he definitely wasn't gay for his own underage grandson. But all of his efforts failed miserably, his mind almost immediately correcting his focus back to Matt, a desperate need for the boy growing larger and larger with every second that went by like a drug addict craving for his next hit, sweat pouring down his chin. With shaky hands, he reached for the car key and turned the vehicle on, pulling out of the parking lot and heading towards his own house instead of the hospital like he had originally intended to. His breathing was frantic and panicked, the lust inside of him overtaking his body, thick and yellow tinted precum seeping through his underwear as he tried to at least halfway focus on the road ahead of him. Zachary pulled up to his driveway after some time, stopping the car and turning it off, wiping his face and sighing as he took a second to just sit still, trying to piece his mind back together. Out of the corner of his eye he noticed a familiar young kangaroo peeking at him from one of the neighbour's windows, grinning and winking before disappearing behind the curtain, a car with a nervous and unfamiliar looking man stepping out and walking inside of the house, welcomed inside by Adrian. The fox stepped out of his car, walking inside and closing the door behind him. He could hear the sounds of his grandson walking and playing around upstairs, freezing completely still as his heart skipped a beat, a switch flipping in his head. He made up his mind: he had to do it. 

His mind set on sharing his newfound gift with his grandson, Zachary put his brain to work on how exactly he should approach the issue, leaning against a table and slowly massaging his erection through his pants as he pondered, fidgeting around. He was anxious to get to work, but he knew that he couldn't just immediately go for it, that would risk the kid being spooked and getting away before his seed began to work its magic. Finally, an idea sprung to his head, the fox scrambling over to the fridge and pulling out a carton of milk, pouring a glass half full of it. He set the glass down and pulled the band of his pants down just enough to slip his dick out, the red rocket sore for some release. He began jerking himself off, heavy droplets of his precum splattering onto the ground as he huffed and bit his lip, one hand stroking his shaft while the other kneaded his knot. Having already been on the edge for nearly the whole duration of his drive, it didn't take long until the man grunted, the first rope of his load on the way out. He quickly grabbed the glass of milk and held it out in front of his crotch, dunking the tip of his cock into it before finally letting go, moaning as he pumped his sperm into the liquid, the large glass quickly filling up and turning slightly off white. A few drops of the milk overflowed and spilled onto the ground before Zachary was done, the canine carefully setting the glass back down onto the table and stuffing his dick away, still half hard even after an orgasm. He grabbed a spoon and stirred up the milk, making sure his special additive was completely hidden and thoroughly mixed in before calling out upstairs, 
"Matt? Do you wanna come downstairs for a snack? I bought some cookies for you, the ones I know you like."
He grinned as he almost immediately heard small footsteps tapping along and down the stairs, the young fox soon after sprinting into the kitchen. Matt stopped in his tracks and looked at Zachary, staring at the man in confusion, 
"Grandpa? What did you…?" 
Thinking on the spot, the grandpa smiled, 
"Oh, you noticed, huh? I tried dying my fur, grandma said my coat was really starting to grey from age. What do you think, makes me look a lot younger, right?" 
Matt nodded before Zachary continued, pulling out a bag of cookies from the cabinet, 
"Now c'mon, sit down and enjoy some milk and cookies."
The cub hopped up onto one of the seats, grabbing the glass of milk with both hands and taking a gulp of it, the man grinning and watching slyly while he poured out some of the cookies onto a plate. Matt grimaced slightly as he wiped his muzzle of the thick and creamy drink, smacking his lips a few times, 
"Why's the milk all salty and stuff?" 
"Oh, it's milk from a nearby farm, very high quality, and very freshly milked. Tastes good, doesn't it?" 
The boy shrugged before taking another large sip, chasing it down with a cookie as the grandpa watched closely, stealthily jacking himself off under the table. 

As Matt was nearing the end of the glass of milk, having scarfed several cookies with it, he slowly began feeling slightly off, an odd tingling in the core of his body, his breathing becoming more shallow and his focus slipping away. He finished the glass before staring off at a wall, sighing and grunting, holding his head. Zachary stood up, the outline of his cock visible in one of his pant legs, the cub too confused to take much of a notice as he knelt down in front of the boy, 
"Something wrong?" 
"I feel a bit… I dunno…" 
"Here, let's get you to the sofa to lay down for a while~" 
The man put one hand on the kit's back, holding Matt's hand with the other, leading him to the living room and helping him lay down on his back on the sofa, kneeling down next to him, 
"There you go, just relax and let me take care of you~" 
Mumbling and writhing around slightly, the cub felt too weak and discombobulated to do anything as he watched his grandpa reaching down towards his crotch, snapping open the button of his shorts and tugging them completely off along with his underwear, his small sheath and balls left exposed. Zachary leaned down to push his muzzle between the alluring thighs, unable to resist giving them a long and slow lick, pulling his own cock out as the boy whimpered quietly. He slipped one of his hands under the boy's shirt, pulling it up and over Matt's head, pushing his muzzle into the fluffy fur on the kid's chest and taking a deep sniff, inhaling the young and immature yet unmistakably masculine musk. He climbed up onto the sofa, laying down on top of the boy, pushing his own body as close as he could to his grandson's and rubbing them together as he moaned, his dick throbbing against Matt's belly as he leaned down to whisper into the cub's ear, his breaths unstable, 
"I was given a great gift, and now it commands to share this gift with you. I know you'll love it, in the end you'll not be able to live without it, you'll see!"
The old fox pushed his lips up to Matt's muzzle, the boy's whimpers and whining quickly disappearing into muted moans as he felt the man's tongue invading his mouth, sweeping across the walls of his maw and wrestling with his tongue, his grandpa's hot breaths making his cheeks blush as the tip of his dick peeked out from his sheath. 

Zachary pulled back from the kiss, panting heavily as he rose up to his knees on top of the cub, shuffling closer until his crotch was right up against Matt's muzzle, the boy's arms pinned down against the couch by his legs. The man grabbed the kit's head with one hand and his muzzle with the other, prying it open. Matt closed his eyes and tried to wriggle back and forth, his attempts at getting away making no headway as the older fox pushed his erect cock inside of the boy's maw, closing the muzzle tight around his shaft as he moaned loudly. He began slowly humping the cub's mouth, his hands keeping the head still as he thrust into it, shuddering and groaning with every push, drooling from the sides of his mouth, his uncontrollable urges finally getting some relief. The grandkid tasted the man's salty precum spurting onto his tongue, swishing it around his maw, unable to spit it out, eventually swallowing it down his throat. With every glob of pre that he guzzled down, he began feeling more and more lightheaded and off, his limbs feeling very light and his head starting to ache slightly. But the most obvious effect was felt on his crotch, his small cock fully hard and erect, his knot pulsing as it grinded against the other fox's ass cheeks. He had never felt his length getting that hard before, nor had he ever experienced that amount of pleasure from just some light touching, his toes wriggling around as he moaned and whimpered. Zachary's knot bumped up against the cub's lips, another rope of precum oozing from his tip as he took one of his hands off the top of the boy's head and reached back with it, groping around his grandkid's crotch, giving the tiny stiffie a few quick strokes before moving even further down, the tips of his fingers brushing up against the kit's tailhole. He circled the rim of the asshole with one of his digits for a few moments, teasing the boy before eventually pushing inside, his initial load and his precum having pacified the young canine enough to only get a quiet grunt and a slight shift from the cub as the finger sank inside. 

Zachary fingered and fucked the boy's maw for several minutes, losing himself in the moment, his chest rising up and down as he gasped and moaned, absorbed in a state of bliss the likes of which he had never experienced before in his life, just the cub's tongue better than anything his wife had to offer. His lustful eyes narrowed as he suddenly pulled back from the slick muzzle, his dick dripping with spit and thick precum as he caught his breath, only a hair away from an orgasm. He wanted to save the fireworks for the main event, looking down at the nearly delirious young fox, Matt slowly blinking and huffing, the boy's half lidded eyes staring off into nothingness. The old man smiled with a toothy grin, surmising that the cub was sufficiently prepared for what he had been waiting for. He grabbed the kid by the sides, picking up Matt before sitting down on the sofa, gently setting the kit down on his lap, his cock poking through the boy's legs. Matt groaned groggily, looking down at the red rocket grinding between his thighs, his head swaying from side to side. Zachary slipped an arm around the kid and lifted Matt up, using the other hand to grab his cock and squeeze it between the two ass cheeks in front of him, pushing his tip right up against the tight tailhole. Slowly, he loosened his grasp on the boy, letting gravity pull the small fox downwards onto his shaft, grunting as the hole began to envelop his length, the snug ring squeezing and throbbing around it. Matt moaned in discomfort, his whine getting louder and louder as more of the length slid inside of his ass until he was howling and sobbing, weakly trying to lift himself off of the cock but managing only to further pleasure his grandpa, sliding his tailhole up the rod before stumbling and gliding it down even deeper. He was confused and panicked, not old enough to have any prior knowledge when it came to sex, his mind completely clouded by the dose of the virus administered orally. 

Zachary pulled the boy down and bucked his hips up hard, slamming his dick deep into the tailhole as he grunted, his whole body on fire with pure and condensed lust. The boy yelped and whimpered, clenching up and holding onto the man as his virginal hole was stretched wider and wider, the girth showing no signs of slowing down before finally he felt the knot bumping up against his hole, giving him a second to breathe and try his best to acclimate to the feeling of being hilted as his grandpa enjoyed the moment. Zachary gritted his teeth and roared as the searing hot walls of the cub's asshole hugged his shaft, the kit's body working on pleasuring the man as hard as he could, even if he didn't consciously recognise that fact. He was bounced up and down on his grandparent's lap, every stroke drawing a sharp and short scream from him, his own small dick flopping all around, a few tiny droplets of precum leaking from his tip. Zachary held the boy as close to his body as he could, revelling in the smell, the feel, the sound, and even the taste of it all, his mind completely absorbed into the moment. All notions of not being into other males or not being into young boys had entirely been forgotten by him at that point, any feelings of guilt or doubt about the changes in him wiped away. He wasn't thinking about his dear old wife, nor could he even, his internal transformation finally complete, the virus having rewritten everything that it had deemed important. The fox thrust up against the cub as he growled, his knot splitting the young canine's ass cheeks apart before plunging inside. 

Matt's back straightened up as he froze stiff, his mind almost shattering from the mixture of simultaneous pain and pleasure, his jaw hanging open as a warbling and shaky cry rang around the room. The knot tied to his tailhole throbbed and drummed with vigour as a huge torrent of cum began pouring deep inside of his bowels, the rush of warm and thick liquids filling him up quickly, a small trickle of the seed seeping out from under the knot, smearing into the warm red fur of his ass cheeks. As more and more of the sperm flooded into the boy, the virus entered his body, beginning almost immediately to make rapid changes to allow for yet another pawn to help spread the infection. Zachary grabbed onto the kid's red rocket and began to frantically jerk him off, the shaft twitching only after a few seconds, spurting out a few thin ropes of nearly colourless fluid. However, after another several shots of immature cum, the cub's tip began overflowing with seed similar to his grandpa's, the watery cum replaced with thick and plentiful globs with a yellow tint. He groaned and suddenly began convulsing, his muscles spasming uncontrollably, his eyes rolling into the back of his head as he slowly lost consciousness. Zachary simply held onto the boy, moaning and sighing as the seizure sent rolling waves of clenches down the length of his shaft, milking out every last drop of his sperm. He yanked his knot out from the ravaged tailhole, letting his load ooze out onto his lap as he let the cub fall down onto the sofa, scooping up a handful of the cum and smearing it onto Matt's belly and chest as he smiled, 
"I think your friends are really going to enjoy the sleepover, we'll make it extra special for them~"
