Family First
This turned out longer than expected. There's a lot of dialogue and transformation descriptions before the sexy action. So skip the first half of to simply get a male/male wolf/wolf incestfest. Or, if the "were" part of werewolf is what floats your boat, read the first half. Everybody wins! Except for people who don't have weird fetishes.
And speaking of people who don't have weird fetishes... don't read this story! I can't be held accountable for any unwanted memories or erections accumulated during the reading of my twisted writing. I can only show you the door. You're the one who has to walk through it.
And with that said... on with the show!
================================================================
Seth's fingers danced over the piano, teasing a nocturne from its tear-soaked keys. He'd been sitting in his brother's cabin hideaway for about an hour now, quietly crying as he softly played the instrument. But the sonata was slowing. By the second it sounded clumsier and more erratic. He tried to maintain the tempo and hit the right notes, but before Seth's very eyes, his fingers were changing, becoming shorter and stubbier. Dark fur was sprouting from his hands, and he felt pads forming beneath them. The nails of his previously nimble digits began to darken and lengthen into malicious looking claws. Within minutes, what was once a virtuoso performance had been reduced to childish pawing at the instrument.
Seth cried out and quickly stood up from the piano bench, causing it to fall.
"For Christ's sake, could you be any more melodramatic? Playing fucking nocturnes while sobbing over the piano? You are such a drama queen! You know, for somebody related to me, you really are a baby."
Seth looked in the direction of the voice. Standing in the doorway was a tall, muscular, anthropomorphic wolf. His brother Jared, who'd bitten him 'for his own good'. He was naked and his entire body was covered in pitch black fur. The only things that stood out from his dark frame were his icy blue eyes and the fanged grin he wore all the time.
"I mean, what's done is done," Jared continued, casually leaning against the wall. "No point crying over spilled milk, eh? I mean, it's not like you can ever go back, so why shed tears over it?"
"You didn't even ask me if I'd be okay with it."
"Well, if I'd asked, you'd have said no, so-"
"THEN WHY DO IT?!" said Seth, angrily cutting him off.
"No need to get testy. And as I said before, I did it for your own good."
"Yeah, you said that right before you bit me. Care to elaborate?"
"Not particularly." Seth scowled at him. He hadn't fully transformed yet, but a thick coat of charcoal fur was quickly covering his entire body. "Okay, fine. But you should take your shoes off. And you should probably take the rest of your clothes off as well, but-"
"No."
"-but I know you'll just refuse." Jared sighed. "Alright. How could turning you into a werewolf possibly be good for you? Well first of all, in a few minutes you'll be much almost as attractive as I am."
"Are you being serious right now?" Seth was livid.
"No. But you really should take your shoes off." Seth reluctantly complied. "And it was also inevitable. You've seen a few of the outbreaks on the news right? Werewolf bites and attacks? Well that doesn't do our numbers justice at all. We're everywhere, and we're growing. So I thought, 'Gosh, why not help my little bro out? Why not give him a little nibble before any other mean old wolves do?' And so here we are."
Jared smiled, revealing the sharp canine teeth lining his muzzle. Seth had one shoe off, and his feet and legs already seemed to be popping and changing shape. "F-fuck, is it supposed to hurt this much?" Seth yelled, a clear note of panic in his voice.
"Only if you have shoes on."
Seth managed to wrench the other one off just in time to watch the anatomy of his legs change. They were already covered in dark gray fur, but only now were his muscles and bones shifting. He watched as his feet lengthened becoming more pawlike, and shuddered as he saw claws grow from them.
Seth's heart was pounding and he was breathing quickly. As the changes slowed, he panted out "Okay. What happens next?"
"Okay, well you've got the fur and paws. Next is... your dick. I told you to take your clothes off, but you refused. When will you simply learn to listen to your wise old brother? If you're lucky, you might be able to see your human cock one last time, but I wouldn't count on it!"
Seth had already risen and was wobbling on his hindpaws. He frantically tried to pull his shirt and pants off, tearing them with his new claws in his haste. Eventually the tattered garments fell to a pile around him. Finally naked, he gazed as his crotch. All he saw was an expanse of dark gray fur.
"WHERE IS IT?!"
"Oh, sorry about that, pup. About 30% of wolves go through a gender swap. I didn't think you'd be one, but that's just how the cookie crumbles, I guess!"
"WHAT!?"
"I'm joking. What, you thought you were a girl with balls?" said Jared playfully, giving his younger brother's furry sack a squeeze. Seth backed away at his touch. "No, it's in your sheath." Seeing his brother's look confusion, Jared went on. "It's not that complicated, but if you really need me to find that for you too, I guess I can help you out. C'mere pup!" Jared was laughing as he reached for Seth's crotch again.
"Don't touch me!" Seth swatted his brother's paw away. "I mean what the hell, we're brothers! No. I'll figure it out on my own. Later. And quit calling me pup."
Jared stepped back, lifting up his paws, "Okay sheesh, no need to get fussy. I mean, we're both wolves here right?"
"Shut up! I... well... what happens next?"
"Your head. And if you ask me, a change couldn't come to it soon enough!"
Seth lost control when he heard this. "Do you have a mirror or something?"
"Nope, no mirrors in this house. Except for the ones in the bathroom."
Seth dashed to the bathroom and Jared sauntered after him. Looking into the mirror, he saw that his nose and mouth had already started pushing out from the rest of his face, forming a muzzle. His nose was darker too, and wetter. He opened his mouth to see that his teeth had become sharp jagged points. His ears became more triangular, and he watched in horror as they rose higher up on his head. Or he thought it was horror. The wolf's face in the mirror didn't reflect that expression very well. Seth could hardly believe the mirror reflected him at all.
The changes slowed and any hint that he might have once been a human had melted away. His eyes weren't even the same color anymore. They'd become grassy green gems amidst a sea of gray. He brought a hand - a paw - up to his face and touched it in disbelief. He didn't even recognize himself.
"I'd say you turned out great!" Jared said jauntily as he slapped Seth's furry ass. He let out a yip, then quickly regained his cold, angry disposition. "Oh, and your ass reminded me. One last change, then you're done."
"Oh, let me guess," Seth said, turning to face his brother. "A stupid, pointless, fluffy little tail."
"Yep."
Seth felt the pressure building in his lower back before he'd even heard Jared's response. It felt like somebody was pressing really hard there with their finger. The pressure kept building, reaching painful levels. Then it suddenly released and he felt something press outward. He saw a furry shape behind him. Then he felt it move. He had a tail.
"And that's it! That wasn't too bad, right pup?"
Seth didn't respond.
For the first time since he'd bitten him, Jared felt a pang of guilt. "Look... I'm sorry. I don't know what to say. I guess... well... I didn't know you would take it this badly. C'mere." Jared held out his arms for a hug. Seth sullenly approached him. "There you go. You know, I actually thought you might have liked it. I know I did, after I got over the initial freak-out. Might have just been because my boyfriend changed me, though."
"Wait, you're gay too?" In his surprise, Seth momentarily forgot to look angry.
"I guess that's what you call it." Seth began to hug Jared more tightly. "So I guess you're not mad at me anymore? I mean, this is a pretty good hug."
"I'm fucking furious. But... you're all I've got." Seth ran his fingers through the soft fur on his brother's back. "And I guess being a werewolf couldn't be too bad could it?" Then he felt something odd.
"Um... Jared?"
"Yes?"
"Do you have a boner?"
"Maybe." Seth quickly backed away from their embrace. Jared looked defensive. "You can't blame though! I mean, first of all, we're both naked. And second of all, you make a damn fine wolf."
"But we're brothers! I don't think-" Seth trailed off when he glanced down.
The giant cock that met his gaze made his heart skip a beat. It was like nothing he'd ever seen before. 11 thick inches of throbbing crimson meat, jutting from his brother's pitch black sheath. The pointed tip was drooling with pre, and two beautiful tennis-ball sized orbs were suspended beneath it. He didn't know how he hadn't noticed them before. And now that his brother's cock had caught his eye, he couldn't stop looking at it.
Eventually Seth managed to tear his gaze from his brother's cock, and he blushed, his new ears folding back in embarrassment. He paused for a second, his eyes flicking back and forth from Jared's face to his dick. "Um... is that what mine's going to look like?"
"Only one way to find out" And then without warning, Jared grabbed Seth's thick sheath. Seth gasped and tensed up at the feeling of somebody else touching his newly changed manhood. Without hesitation, Jared began to gently squeeze and rub it, eventually grabbing Seth's balls with his other paw, massaging them.
Seth couldn't believe what his brother was doing. His own flesh and blood, unabashedly handling him like this. It was wrong, he thought, they were brothers. But his thoughts didn't end the feelings of arousal, nor did it stop the blood from pumping into his rapidly growing dick.
Jared dropped to his knees to get a better look of the action, never ceasing his continuous kneading of his younger brother's sheath and balls. Soon the pointed red tip of Seth's cock was poking out, and Jared decided to give it a short lick. He heard Seth gasp again.
"Pup likes it when I lick his cock, doesn't he?"
Seth, eyes closed and panting, gave a short nod of affirmation. Jared flashed a quick predatory grin, and continued licking his brother's manhood, lavishing his brother's sheath and balls with his tongue. The pleasure created by Jared's warm wet tongue was immense, and soon Seth's cock had been coaxed to its full size. Then Jared stood up.
"Well, looks like we might be related after all, pup."
Realizing that the tongue bath had finally stopped, Seth opened his eyes and looked for what his brother was referring to. Then he saw his own canine cock, twitching with arousal alongside his brother's. It was huge, red, and slowly being stroked by Jared's right paw.
"Would you look at that," Jared said, moving in closer bringing his dick next to the other wolf's. "Almost as big as mine."
Jared saw Seth's tail wagging behind him, and took that as a sign to continue. Without a second thought, he took both of their dicks in his right paw and began stroking them together.
"You like that, pup? You like it when I rub our cocks together like this?"
Seth hoped to god that his brother's question was rhetorical. He could hardly think right now, much less speak coherently. The only things that passed through his muzzle now were pants and animalistic moans of pleasure. He couldn't believe what his brother was doing, but at the same time he couldn't fathom anything sexier.
"Answer me, pup."
"Uh... Yes, ungh... I like it a lot!" He looked down and saw their two cocks being rubbed, dribbling pre, being squeezed against each other. He felt their balls rock into each other with each stroke. Seth could hardly stand the pleasure, but at the same time he needed more.
So he grabbed Jared and kissed him. He let his flexible new tongue explore Jared's muzzle, while his paws explored the curves of his brother's warm muscular body. He felt Jared's other paw come around him and squeeze his furry ass while their lust-fueled kiss intensified. Soon Jared started to pump their cocks faster, causing Seth to sink further into his feral desire.
He broke the kiss to let out another moan. "Please don't stop!"
Jared looked into his eyes and smiled mischievously. "You don't make the rules around here pup." And with that, he let go of their cocks.
Seth didn't understand. "What?" he whimpered. Then without speaking Jared roughly grabbed his brother by the dick, and lead him to the bedroom.
"On the bed, pup. Paws and knees, bent over."
Seth obliged, staring back at his older brother longingly. Jared followed him onto the bed. "Lift your tail, pup."
Using muscles he didn't know he had, Seth lifted his tail, presenting his round ass and tailhole to his older brother. He knew what was coming next. And as much as it disgusted him to want to be fucked by his brother...
He wanted to be fucked by his brother.
A lot.
Jared came up behind him, laying a paw on Seth's lower back. With his other paw, he took his dick and smeared precum around Seth's awaiting entrance. He continued teasing Seth's hole until he heard the gray wolf let out another whimper.
"Aww... does little bro want big bro's cock inside him? Does the pup want a big wolf dick to fill him up?"
"Yes! I do!"
"Are you sure you can handle it, pup?" As he was saying this, Jared had reached around and began slowly stroking Seth's dick. "Are you sure you want this big spear of a cock shoved into you?"
Seth was going crazy with lust. He didn't care if he'd have to beg, he just wanted more. "YES! I WANT YOUR COCK!"
"If you insist."
And with that, Jared shoved halfway into his brother, packing his brother's tailhole with his thick cock. And without missing a beat, he continued sliding it, excruciatingly slowly.
As that monster cock sunk into him, Seth almost regretted begging for the cock. It hurt like hell, and Seth felt tears welling up in his eyes. He'd taken cocks before, but none this massive. And it kept sinking further and further in, filling him up more and more. It kept spreading his cheeks wider as it disappeared into the younger wolf. He felt like a rubber band stretched to the point of snapping, as inch after inch of that slick rod eased into him.
Yes, he almost regretted begging. But the pain was fading. Soon the pain of being stretched was melting into the pleasure of being filled. Jared's paw was pumping away at his cock the entire time and soon Seth was back to panting in lust, wanting nothing more than for his own brother to fuck his furry brains out.
Finally Jared hilted, his furry hips resting against his brother's ass. Seth felt so complete, his ass nestled into his brother's warm crotch. But that feeling was short lived, as Jared quickly pulled back out. He brought his hips back to the point where only the slick tip of his cock was still in his brother, and then immediately shoved back in.
It almost hurt as much as when Seth was first being entered. The shove was merciless, and it made Seth's whole body shudder in pain. But like before, the pain faded, leaving Seth with one thought on his mind: more.
Jared repeated, and eventually got a pace going. He had stopped stroking Seth's cock, but Seth wouldn't have needed the extra stimulation anyway - his head was thrown back in ecstasy, any indication that he was once a civilized individual had faded in the brutal fucking his brother was now giving him. Soon he was eagerly pushing back into Jared's powerful thrusts, their bodies colliding heavily on each impact.
"You like it when I fuck you, don't you pup?" Any cute condescension in Jared's voice had vanished, being replaced with a lustful, dominating hunger.
"YES! I LOVE IT!"
Jared sped up his thrusts even more. He felt his baseball-sized knot forming, beating against Seth's tailhole, and knew that it wouldn't last much longer.
"You feel that, pup? That's my knot, and it's going inside you!"
Seth didn't even hear him. He was howling with pleasure, and wouldn't last much longer either. He felt Jared's thrusts becoming more energetic and frantic, his brother's cock sliding in and out of him wildly. And he felt something big and round at the base of Jared's dick.
The thrusts were coming harder and harder, with that big round thing being pounded against his tailhole, until finally...
It popped into him.
Jared threw back his head as his cock exploded deep inside his brother, pumping the young wolf with his warm sticky seed. His cock twitched wildly as he filled his brother more and more, his thick knot preventing any semen from leaving.
Being pumped full of his brother's seed sent Seth over the edge as well. He violently orgasmed, his entire body clenching and unclenching as his cock fired his wolf spunk everywhere. It coated his chest, and soaked the sheets below him, as his body was immobilized with pleasure.
And as suddenly as they started, they stopped. Both of their orgasms subsided, and the tied pair rolled onto their sides, where they collapsed into an exhausted but well-deserved sleep.
Seth woke the next day with his brother's furry arms wrapped around him, feeling sore and sort of disgusting. His ass felt like he had slept with a Saguaro cactus in it, and his fur was full of dried semen.
"I can't believe I just had sex with my brother." Seth's mind was racing.
"What are you talking about," said Jared groggily, as he too awoke. "I don't look anything like your brother. I don't have freckles. Me, I just found this attractive and surprisingly hirsute stranger prancing about my cabin, and I decided to have some fun with him."
Seth didn't seem amused. "I mean really, this is like some kinky story you'd read on one of those fetish websites. I mean, werewolves? Gay werewolves? Who are related?"
"I wouldn't know about any of those websites. I was always on Team Edward myself."
Seth paused thoughtfully. "Wow... you... really have no qualms at all about incest."
"You were begging for it. I did you a favor."
"What about your boyfriend?" Seth objected.
"Family first."
As much as he wanted not to, Seth couldn't avoid laughing. "You haven't changed at all since we were kids." Seth rolled out of the bed, and stretched. "Well," he said, looking at his matted fur. "I guess I'll go take a shower."
"I'll be right behind you, pup."
Several objections crossed Seth's mind, but he decided not to voice any of them. Instead he smiled as he walked to the shower, tail wagging behind him.
