Sven approached the teen slowly, unable to prevent his cock from spilling its seeds onto the floor with every step he made. The pup's eyes were fixated on his lengthy red wolf erection, watching it growing thicker and even longer with Sven's arousal. Sven slipped his clawed hands underneath the teenager's arms and lifted the lightweight pup easily.
"You will not remember this," Sven lied, and licked his tongue across the pup's face as the pup raised his stare. "Wrap your legs firmly around my abdomen if you don't want to enjoy these new mating pleasures, pup. Lean your head back and I'll be quick as sunset in the moon sheen of winter."
"The moon what?" Matt questioned, cringing away from the werewolf's drooling licks. "I thought y-you said I'd get to choose to be your um, your mate, once I was a werewolf you said. Please stop licking me! It ... it's too gross!"
Matt Foster shuddered from the werewolf's strange odor. It was nothing like his dog's scent, but Spinner was a Beagle-coondog canine mix unlike any other mutt anyway, and he was the first one the werewolves had silenced by letting him loose from the choke chain restraining the howling mutt at the side of their farmhouse.
The werewolf smelled like their horses after a humid day, sweaty and tangy, slightly meaty. The werewolf finally stopped licking him, but now the beast was sniffing him, leaning its black muzzle far closer to him than he thought necessary. And its breathy snorts tickled despite the wolf snout's spittle spraying onto his face and neck, drool spilling downward onto and against his bare chest.
Then the huge maw opened, exposing ivory white fangs. Four three-inch long upper canine fangs stretched strings of ropy saliva between the tips of them from four pointy lower canine fangs curving slightly inwards to form what would be an inescapable bite once they closed, and Matt leaned his head away from the dripping mouth lowering and twisting toward the front of his throat. The beast lied. It didn't want to turn him into any werewolf, or a mate! The werewolf wanted to take a bite out of his neck or tear off his head and feed on him. And then he felt its long wet tongue press onto flesh, licking and soaking his throat, and Matt wildly fought back.
"No! I changed my mind!" Matt screamed, kicking at the werewolf's legs, knees slamming into its solid muscled thighs without effect. "Stop! Oh jeez, please stop! Don't eat me! I'm just a kid. I'm not big enough!"
But Matt had seen what one of the werewolf beasts did with his baby sister, and she was only a 5-month old infant. It bit her in two and swallowed each half, bones and all, like she were a tasty appetizer.
Matt struggled more furiously when its fangs began to clamp down and around his neck, roughly forcing him to press up against the soft silky pelt of its warm sweaty chest.
Sven slid his hands downwards along both sides of the slender pup's abdomen, flexing his erection and spreading the teen's kicking and swinging legs with his stiffened red cock and slowly lowering him onto its upright slime coated stiffened tip.
The pup's moan alerted Sven the instant the human realized what he was doing, and used that exact moment of motionless shock to stab the tip of his cock into him and penetrate the tight young rectum. The pup struggled uselessly now, squirming on his cock so violently it had even managed to help slide its leaking tip inside another inch and bring Sven closer to his full mating discharge.
Feeling the pup's horror and suffering increase as his erect hard length grew warmer in its approaching orgasm, an orgasm that he was purposely prolonging for the larger, more powerful release of his mating seeds lengthy and abundant ejaculation, Sven snaked his arms upward along the boy's back. He gripped his hands around the boy's shoulders and started to slowly force his shaft even deeper inside the youthful virgin pup.
Sven wasn't aware that when his oozing cock stretched and ripped virgin muscles within the boy that the human had instantly absorbed his seed, spreading Sven's own genetic material throughout the human's tissues and fluids, tainting the blood returning to his human heart as it spread through the human's DNA and began to speed up the pup's transformation.
Within seconds, the teenager was angrily pounding his fists against Sven's chest in his resistance at both the pain below and the internal changes rapidly spreading through human organs and altering bones.
Matt's struggles were cut short when the increasing new pains below suddenly knocked him unconscious again.
Sven's hard swollen mating knot's thicker 2" bulge, 4" from the base of his dark red 12" erection, forcefully stretched and squeezed its 3" long growth deeper inside the pup's rectum, tying the human onto his large shaft as human muscles tightened around Sven's sheathed 12" wolf cock.
Sven released his jaws gentle grasp on the boy's throat, embracing the unconscious human teenager and flexing his stiffened shaft in the throes of ejaculation, forcing the boy immediately awake and back to full consciousness.
"Watch and feel how we become mates for each other," Sven said, releasing a thick lengthy discharge of hot seed into his mate. His knot would tie the young boy on his erection for two to three hours. "You're my lifelong werewolf mate whether you want your own arousal and my same sexual pleasures or not, pup. Even if you try to fight them, you will have all of my own needs now, too."
"Oh jeez, it-it's too, oh no it's oh ... too big," Matt groaned, and dragged his face across the werewolf's damp chest fur. His inhaled gasps choked him, and breathing made him cringe from the strong smells that clogged and saturated the inside of both nostrils. "No! I-I'm not your mate I'm-I'm, oh God, it hurts, oh crap it ... ah, what's it doing? I can almost feel it p-ahh pump-pumping. It's making me get a-a oh jeez no! Not-not mine, too! My-my cock! It-it's getting me so hard I-I'm getting a hard-on!"
Nauseous from the excruciating and outrageous penetrating pressure Matt felt from between his legs up into the deep interior of his abdomen, and also from the heat of the strong hot flow of the werewolf's fluids streaming inside him, Matt was horrified that the beast could really be doing this to him. He wasn't sure if it was pumping its cum inside, or its urine, but his brain wasn't willing to give in and accept the horror that there was a steady heated flood being transferred inside him despite the erection it was giving him.
He'd seen his older brothers shoot a load of cum, hidden from view, but their orgasm's had ended quickly. Less than a minute. But this creature was squirting and discharging a long powerful flow inside, an impossible lengthy hot blast that grew warmer with each throbbing flex of its huge stiff penis.
And his cock was getting fully erect, popping an undeniable boner from it, too.
Sven growled softly with more arousal when he felt his pup now responding with his own stiffening erection and the sudden awareness of his own human body's growing arousal. At least his body fluids were adjusting and increasing the pup's pleasures to reveal its altered and new found hungers Sven's seed was now giving the shocked human male.
Soon, the pup's own blood would become purebred werewolf blood, or it would turn him feral and permanently transform the boy into a savage feral animal. His kind often used the hides of those that had turned too feral, peeling the skins off the least fouled smelling creatures to use for bedding, or refining the skins and body parts into extra armor if their pelts were too dirty or ripe to use inside their den or lair.
Watching the pup's dark eyes fade to pale gray and then become white, Sven inserted his tongue roughly inside the boy's mouth, scouring the front, sides, the upper and lower areas inside it, and then sliding it down his throat and transferring ample saliva to make sure his mate enjoyed his favorite means of shared sexual pleasures when they were mating.
Matt wasn't sure why he was so hard, getting an even stiffer boner despite feeling sick and nearly choking on the thick fluids the werewolf gave him as it kissed him, feeding him its slick drooling tongue.
He'd pressed both hands to its chest as it plunged its long tongue up and down his throat for several minutes, and his cock swelled harder as though he were beginning to enjoy this! He didn't enjoy it. It was horrible, and the warm tastes of its hot saliva almost made him puke. But Matt felt his cock throbbing on its own, and when the werewolf's tongue filled his throat, held deeply inside, fluids pouring down his throat, he'd even helplessly ejaculated from the feel of everything now happening to him.
Matt gazed downward, groaning in pain as his abdomen tightened, sucking inward slightly before it suddenly hardened and bulged with the outline of new muscles being sculpted at his slender stomach. His abdomen was growing slightly longer, too, and as solid bumps across his abdomen swelled into the firm six-pack of muscle even more solid and larger than his oldest brother's abs, his pecs expanded to form the harder rounded muscles of a noticeably more impressive muscular chest and stronger physique.
Matt felt his thighs and leg muscles growing larger, harder, and more powerful as well, bulging calves and muscles even down into his feet. His feet were growing larger, Matt quickly corrected, startled by how quick and strange his lower body seemed to be bulking and growing hard with more muscle, changing every inch and prior familiar form into a more developed, older-looking new shape.
Older! He'd gained a more muscular physique, like that of a teen slightly older ... just like the werewolf's same physique. His legs looked just like the werewolf's legs, but without that thick white fur coating them and concealing the hard muscle. And now it excited him, making him get even hornier.
And wrapping his larger, longer legs around the werewolf's waist, Matt felt the painful hardness still deeply impaling him wasn't as painful like this. He wasn't surrendering to the werewolf's sex, but the decrease in pain was a welcome relief.
Pain enveloped Matt's cock, and looking down at it he saw that his bloated mushroom head was thinning and changing into ... oh jeez no not ... OH NO! Matt shuddered from the clearly similar shape that his cock was becoming, resembling the werewolf's own cock.
It didn't have a mushroom head on its huge tip any longer. Instead, the tip was pointed, like the silky white pelted werewolf's large cock, no, it looked just like the werewolf's glossy red penis! And watching in horror as his mushroom head disappeared and became more pointy like the blond werewolf's, Matt saw the veins on its hard length fading when the shaft turned dark red and smooth,becoming much more slick and glossy-looking.
Something was also happening to it further down, near the base, tapering his cock to an even pointier tip as it bulged from the inside and developed a 2" long thickened growth near the base. A knot just like the knot male dogs used to tie its mate for having prolonged canine sex!
And that's what he had felt, what had hurt him so much before, knocking him out as the werewolf slowly and painfully forced its own sex knot inside his ass, mating with him.
His cock had changed into a werewolf's cock! That must mean I really am being turned into a werewolf, too, Matt realized.
Maybe these werewolves also use their knot's to tie males for sex, Matt thought.
Then Matt felt his cock lift upright, and something else was happening at the base. He glanced down at the glossy red penis, watching as foreskin slid upwards and around its flexing, lengthening stiff length. His cock grew longer, foreskin attaching onto his abdomen and pulling its sheathed longer length upright and into the new warm canine like hairy werewolf sheath.
Matt guessed that his cock reached almost a foot long as the now hidden, fully sheathed pointed tip settled below the grooves of his six-pack's muscles. He hadn't felt it when the white-blond spiked fur started sprouting out over his entire body, but the exact same silky white pelt of the werewolf that had made him quickly blanketed his own flesh. And its smell was ripe and horse-like, meaty and strong.
Sven's wish for his mate to retain his dark features were replaced by his arousal of the duplicate twin his seed was creating. Twins were more rare and always mated one another, but it had been countless of generations with very few twins being made. And it was even more rare when a world was found that could create them.
Sven also knew his new twin would learn the sexual needs in him grew stronger with each mating. Even if he resisted the pleasures now, he'd eventually learn to become more obedient and fully accept what he was, a willing and easily aroused horny mate.
