"Grr" thought Logan. He knew he loved his brother, but this was slightly ridiculous. He was currently tied down to the bed, his hands tied to the headboard. His stupid brother was paranoid that he was going to run away again. After Logan left Victor in Lagos, he had disappeared. Victor had spent several months tracking him down, finally finding him hiding in a cabin up in Canada. He had tackled said brother into the snow, and nearly clawed his face off. After a few punches and some yelling, the two brothers had calmed down enough explain everything. Now that things were settled, they decided to stay together forever from then on. They trudged their way back into the cabin, fell on to the bed, and promptly fell asleep for five hours. Hence were Logan is in his situation now.

He tried to get out of his cuffs, but was unable to. Turns out they're strong enough to hold down a strong mutant like him. He finally decided to stop struggling, cuz his wrist was nearly torn off when he tried. He sighed in defeat, and waited for his brother to come back and let him go. He let his thoughts drift to his brother. Sabretooth. To Logan, he was always Victor. And to Victor, he was always Jimmy. He thought about how he had taken care of him when they were young. All the wars they had been through. They always had each other's backs. But it changed when Victor went a little crazy. His bloodlust had gotten to him, and Logan couldn't control him. That's why he left him in Lagos. He sighed, and decided that it was in the past now. Let it go.

Victor walked in, happy. He was in a good mood today. He killed a few people in the morning. He had a full stomach for once. And he had found Jimmy. He really couldn't see anything wrong with today. It was near midnight, and both brothers were fairly tired. He flopped onto the bed, and dragged his brother over to him. After slicing off the cuffs, he shifted his brother into a more comfortable position, Logan's back to his chest, his ass near Victors crotch. He smiled contently, and whispered into his brother's ear:

"You're never gonna leave. I'll always be here." A warning. Logan grunted in agreement. Victor smirked, and bit his brother's neck to mark him. They drifted into sleep, using each other as warmth, just like old times. During that night, a strange force came through the cabin. It searched for a few minutes, finally finding its target. It split into two, and plunged its way into the two brother's chests. They didn't react, only curling up together. In the back of their minds, they heard a voice.

"There is only one alpha. Use this well." It drifted out of their minds, leaving behind its handiwork.

Next Morning

Logan was first to wake up. He slowly opened his eyes to the brightness of the sun, and abruptly shoved his face back into his pillow. He groaned, not wanting to get out of bead. But Nature was calling. Loudly. He punched his pillow, and rolled out of bed. He slowly walked to the bathroom, scratching his ass along the way. He wandered over to the toilet, did his business, then drifted over to the sink, splashing cold water onto his face. Now awake, he glanced at his reflection. He promptly screamed in shock. On his head were wolf ears. Wolf. Ears. He grabbed them, touching them gently. They were big, and soft. He nearly purred at his own touch. He did the cliché movie thing, turning around slowly. Above the curve of his ass, was a thick wolf tail. He reached down; making sure it was really there. "The fuck?" he thought. He suddenly thought about Victor. What if this happened to him too?

He ran back into the bedroom, and dug his older brother out of the mountain of blankets he had managed to roll up in. His thoughts were confirmed. Although they were a bit different. Living up to his mutant name, Victor had the ears and tail of a saber toothed tiger. The ears looked a bit creepy, jutting straight out Victors head. The tan colored tail twitched on its own accord. Swaying back and forth on the bed. Logan chuckled to himself. He couldn't help but touch the swaying tail; it was so funny to watch! He ran his hand from the base of the tail up to the tip.

Victor woke with a full body shudder. As soon as he opened his eyes he fell back laughing his head off. Jimmy looked so cute! Big puppy eyes to go along with the ears. Logan growled, and sat on his haunches. What the hell were they gonna do now?
