[Alex felt a shiver up his spine as he entered the club, the pulsing music vibrating his bones. The Wolf Den, a place he'd never thought he'd step foot in. But here he was, a part of a bet that he would last the whole night in this gay nightclub. He'd never been attracted to men, but he wasn't about to back down from a challenge.

The club was packed, the dance floor a writhing mass of bodies. The smell of sweat and musk filled the air, and Alex couldn't help but feel a little overwhelmed. He'd never seen so many half-naked men in one place before. And they were all so… muscular. It was like a sea of muscle, and Alex felt like a minnow.

But as he looked around, he noticed something strange. These men weren't just muscular, they were… furries. Alex blinked, unsure if he was seeing things. But no, they were definitely furries. And not just any kind of furries, but muscle wolves.

Alex felt his heart rate quicken as he took in the sight of all these muscle wolves, their furry bodies glistening with sweat as they danced. He felt a strange pull towards them, but not really a desire to be into them.

ignoring the thought. He never have been into men, let alone furry men. He was here for the bet, and that was it.

He tried to make his way towards the bar, but it was impossible to move through the throng of dancers. He felt a hand on his shoulder and turned to see a massive grey furred wolf with red mohawk.

"Hey there," the wolf said, his voice deep and rumbling. "You look lost. Want to join the pack? by the way handsome one my name is hatiowarg, what's yours"

"Alex" almost hesitated, unsure of what else to say. But something about the wolf's eyes seemed to draw him in, and before he knew it, he was nodding.

The wolf grinned, showing off a set of sharp teeth. "Excellent. Follow me."

The wolf led him through the crowd, towards a secluded area of the club. And as they walked, Alex felt a strange transformation come over him. His clothes seemed to melt away, replaced by a thick pelt of fur. His muscles grew, becoming more defined and powerful. And he felt a strange hunger, a desire to be dominated and claimed.

The wolf led him to a large, cushioned area, where a group of muscle wolves were gathered. They turned to look at him as he approached, their eyes filled with hunger.

"This is Alex," hatiwarg said, introducing him to the group. "He's joining the pack tonight."

The wolves growled in approval, their eyes roving over Alex's newly muscular body. And before he knew it, he was surrounded, the wolves closing in around him.

He felt a pair of hands on his hips, pulling him close. He looked up to see a wolf with dark fur and piercing green eyes. The wolf leaned in, his breath hot against Alex's neck.

"You're mine tonight," the wolf growled, his voice low and dangerous.

Alex felt a shiver run down his spine, a thrill of excitement coursing through his veins. He'd never felt this desired before, this wanted. And he knew that he was in for the night of his life.

The wolf claimed him, his lips crashing against Alex's in a fierce licks. And as the other wolves watched, they began to touch and caress him, their claws roving over his furred body.

Alex felt his brand new knot grow hard as the wolves explored him, their fingers teasing and probing. He moaned as one wolf sucked on his nipples, while another wrapped a hand around his thick shaft.

He felt the wolf behind him push him down onto the cushions, his powerful thighs spreading Alex's legs apart. And before he knew it, he felt the wolf's hot, wet muzzle against his hole.

Alex moaned as the wolf licked and teased him, his tongue delving deep inside. He felt the other wolves gather around him, their hands and mouths exploring every inch of his body.

He felt a pair of lips wrap around his cock, sucking him deep into a hot, wet mouth. And as the wolf behind him continued to rimming him, he felt his orgasm building, his balls tightening.

He cried out as he came, his hot seed spurting into the another wolf's mouth. And as the other wolves continued to pleasure him, he knew that he was now a part of their pack, a part of their world.

hatiwarg licked his muzzle with pleasures. as the Alpha he was who take Alex's tail hole, before he spread his legs. the huge red Knot rammed Alex, made him sneer with pleasures.

And as the night wore on, and the wolves took turns claiming him, he knew that he would never leave this new life, he received a spike collar and dog harnesses.

after the long party, at the dawn upcoming, He whatched on the mirror, covered with wolf's cum. his wolf form, "I guess, I'm a furry now" alex murmured, hatiwarg pulled him with a belt from his collar and hugged him "welcome home pup"
