Hey everyone, I know the title for this story sucks but give it a chance please. Also I just thought this up and have quite a few ideas for this story so like I said there may but hints of wincest, much much later in the story and I'm not sure of the rating that is so help is needed for the help of the rating. Also ideas and reviews are loved, thanks!

"Dude, why did you pick here of all places?" Sam sighs, looking around the dark warehouse that seemed to be abandoned. If the huge hole in the rotting metal roof was any hint along with the dusty cobweb covered inside where machinery looked as thought it hadn't been seen inside in years.

Dean grinned at his too tall baby brother "Why not? Come on Sammy! It's not like there's anyone here, hell it looks like the roof is about to collapse!" Dean joked as they walk side by side into the large building; their only source of light was Dean's small flashlight.

Sam glared at his brother "Exactly Dean, this place practically screams 'Danger' from the outside never mind in here" Sam growls, observing what he could see of the walls and the image of the whole building falling and crushing them reached his mind. He groaned inwardly when Dean stopped in the centre of the building and dropped his backpack.

"Aha! Here!" He cried happily, reminding Sam of a small child…. Although Dean was always like a child to Sam. Sometimes Sam felt that he was the older between the two but the constant nickname 'Sammy' reminded him he was the younger of the brothers.

Sam looked at the spot and sighed, dropping his own backpack. They were on the run from the officials from their last job and had needed a good hiding place. Dean had decided it was his turn to pick their hiding spot this time and Sam was starting to regret letting Dean lead the way.

He would never mention it to Dean in fear of an argument but whenever Dean picked the hiding place something would most defiantly go wrong. Although Sam couldn't tell if it was good or bad… the mistakes never happened to him but mostly to Dean.

He smirked as the less dangerous mistakes ran through his mind. He loved teasing Dean whenever something when wrong and neither where badly hurt but Dean's pride would always come out damaged. Like the time he'd gotten himself trapped in the toilets of an abandoned hospital after the part of the roof in front on the door crumbled and piled against the door… good times.

Sam had teased Dean for days after spending hours trying to get him out, being deliberately slow to laugh at Dean's furious screaming. But then their was the bad mistakes, like the time Dean had nearly died after the floor collapsed beneath him and he'd crashed through four story's of the building before he hit non rotting ground.

Sam still mocked him but the worry was always there as he had supported him with his broken leg and arm. Sam sighed, every time Dean picked the place it was an old building… Sam was starting to think Dean liked abandoned places and grinned at the thought of his brother having a deserted building fetish.

Things like this was the reason Sam loved his brother so much, he loved his child like antics even if he made out like he hated them, his protective spark and need to help and protect people. Dean would never admit it but he was soft when it came to helping innocents out.

"Earth to Sammy, come on dude where'd you go?" Dean called; waving a hand in front of Sam's dazed face. This snapped Sam back to reality and Dean's grinning face. Dean looked victorious that he brought Sam from his thoughts and he pointed towards a door in the distance.

"Wanna come investigate this dump?" Dean asked as he searched his brother's face and smiled when he saw annoyance on the younger boy's face.

"Is that why you picked this place?" Sam asked, annoyed that Dean was thinking of investigating in this delicate situation "Remember the last time you 'investigated' an abandoned building?" Sam continued sarcasm evident in his voice.

Dean scowled as he turned away childishly "That was just an accident, not like it'll happen again" he snapped sharply and Sam grinned in amusement as his eyes glinted with mischief.

"Oh so having your clothes stolen by a wild animal was an accident?" he mocked. Dean's face flushed with anger and embarrassment and even though Sam couldn't see his face he could see his brother shaking slightly in anger. Ohhh had he hit a nerve?

"Shut up Sammy, just because you're jealous that even animals love me" Dean said quickly and flustered. Sam chuckled at the reactions of his brother and had to keep from laughing out loud as the last time Dean had went off replayed in his mind.

"Oh that has nothing to do with it" Sam chuckled.

Flashback

"Stay here Sammy, I'll go investigate" Dean ordered his brother who was kneeling on the ground over the backpacks. Sam quirked an eyebrow at his brothers back as Dean made for the back door to the deserted swimming baths.

"Alright dude" Sam muttered as he shook his head and got ready to come running to Dean's rescue as he had too many many times before.

Dean meanwhile had reached the back door and opened it slowly. As soon as the door swung open he stepped outside to be greeted with the hot night air, no wind could be felt as the heat from the day still had the air heated quite hotly.

Dean grinned to himself when he saw a deserted swimming pool, the water still and uninterrupted as leaves from nearby trees floated on the surface. Since he hadn't had a break in a while… Dean looked around to make sure none could possibly see him, mostly his brother before he started stripping.

He felt his childish side bubble to the surface as the thought of cannon balling into the untouched water on a hot night filled his mind. Once he was clad in nothing and his clothes folded beside the pool he paced a way from the pool before sprinting and then jumping once in range of the pool, pulling his legs to his chest as he shouted in glee as he hit the warm water with a rather large splash.

He went under the surface and felt excitement course through his veins as he swam upwards and broke the surface, gasping for breath. He sighed in content as he floated on his back, gazing up at the shining stars, thoughts of his mother came to mind when he saw the stars.

We used to look at them when I was young… Dean pondered a little longer but was brought from his thoughts when he heard a rustling behind him and immediately stopped his floating and twirled round in time to see two stray dogs biting at his clothes.

"Hey!" he cried which succeeded in the dogs becoming startled as one grabbed his trousers and shirt and the other bit into his underwear. Dean's blood suddenly went cold as the animals fled, clothes stuck in their jaws.

"Come back! I'll kill you!" he screamed, grabbing the pool edge and hurled himself out of the warmish water into the now colder air. It wasn't his day he thought to himself as he started running, very aware of his complete nakedness.

"Dean!" he heard Sam scream but took no heed as he took off after the dogs, not knowing Sam had kicked open the door, holding up his gun and flashlight. Expecting danger but instead was met with a sight of his brother he never wanted to see.

He just stood frozen as he saw his brother completely naked, sprinting after two dogs all the while screaming as Sam got a good look at the stark white butt of Dean and immediately felt the need to grab a knife and gorge out his eyes.

End of flashback

Dean huffed as he headed towards the door, completely ignoring his brothers mocking laughs. How could he have known that jumping naked into a deserted outside swimming pool would result in his clothes being stolen?

Still to this day never returned? He flushed in embarrassment as he walked through the door, grumbling as he inspected this new part of the warehouse. He had never gotten those dogs and Sam had been responsible for calming him down and giving Dean some new clothes.

He still never let Dean live it down; he'd had too many bad jokes related to the subject the following months. He sighed as he pushed the thoughts from his head and started flashing his torch around the room and noticed an open door and swore he heard a faint voice.

He frowned to himself as he crept towards the door and stepped carefully inside, making sure to make no noise as he looked around the room and was startled when the door slammed shut behind him. Damn it! He quickly scanned the room, reaching for the waist band of his jeans for his gun.

He should have learned by now that his luck when it came to investigating by himself sucked. He froze when he heard deep cackling from behind him and an icy hand wrap around his wrist, stopping him from reaching his gun. Crap!

He twirled around quickly to see a tall man, maybe even taller than his baby brother, staring down at him. His caught arm now in front of him as he observed the tall and obviously stronger male.

He had light blue skin, his lips a deeper blue then his skin, his eyes completely devoid of colour, only the pupil wasn't white as the man locked gazes with his own green eyes.

He felt his skin crawl as the mans lips turned up into a smirk, his white hair hanging to his shoulders as he moved first, grabbing Dean's other wrist. But Dean reacted immediately, kicking out as he tried to take out the mans legs.

But he couldn't even budge the man so he yanked at his wrists but winced as the man tightened his hold. "What's wrong? I won't bite… much" the man purred, gazing at the smaller male before suddenly wiping the body around and bashed Dean's head, hard against the wall.

Dean heard a sickening crack before darkness consumed him, the last thing he remembered hearing was a scream and low chuckling, not registering it was his own voice.

Sam's head snapped up from the back packs towards the door he'd last seen his brother. Had he heard a scream? Sam frowned in worry as he grabbed his gun and made his way cautiously towards the door, holding up his flashlight and gun.

"Dean?" he called, opening the door and looked around for any sign of his brother, his heart hammering in his chest when he heard no reply his worry rocketed.

Suddenly he had a terrible feeling something had gone wrong. He searched some of the rooms, still no sign of his brother and all the while his worry and concern was almost sky high. He needed to check if Dean was alright.

"Dean!" he shouted, worry and desperation evident in his voice. Was this some joke? Or was Dean in real trouble? He soon cam up to the last room he hadn't checked, the door was tightly shut which made Sam think Dean couldn't have gone inside.

But he was running out of places so he took a deep breath and tried to open the door to find it was wedged shut. He frowned before stepping back and kicking the door open, rushing into the room with his gun at the ready and was amazed at what he saw.

Dean was lying on what looked like a table with a very tall man standing over him, chanting deeply as he pulled out a needle from his brother's arm and Sam saw three other needles already empty and disregarded, one last needle remained.

The man looked up at the taller brother and quickly grabbed the last of the needles, ready to inject but Sam shot his shoulder, earning a pain filled shout as the man gripped his shot shoulder and dropped the needle, the candles around Dean's body went out as the man disappeared in a cloud of smoke.

"Dean!" Sam cried, tucking away his gun as he ran to the still body of his older brother who looked like he was barely breathing.

"Hold on Dean! Hey wake up man!" Sam called, desperate from his brother and idol to be fine. Tears made their way into his eyes when he saw Dean's pale and pain filled face. What had that… man done to his brother!

Sam gathered Dean up and ran towards the car outside, unaware of the changes happening inside Dean's body.

The first thing Dean felt was a killer headache. Had he been drinking last night? He racked his memories and frowned when he remembered the man knocking him out.

He started to feel panicked as the memory of being knocked unconscious flooded him mind, how could he be so stupid! And he'd went down scarily easily… was he losing his touch?

He groggily opened his eyes, whimpering as light attacked him. What the! Once he squinted long enough his eyes adjusted and was amazed when he saw the ceiling in amazing detail. He could see every dint and curve and crack in the paint of the ceiling.

He'd never been able to see so well in his life! What had that man done to him? He quickly scanned the room and noticed he was in a motel room, his brother sitting in a chair beside him as he slept, worry etched into his face.

He felt relief flood through him, making him relax. Suddenly he realised he could hear much better than he could before, along with a heightened sense of smell. He wrinkled his nose as he smelt all sorts of scents as sounds attacked his ears.

Egh! Who was making so much noise? He clapped his hands over his ears… to find they weren't there. He froze. Where were his ears? He started panicking as he felt in place of his ears just the feeling of his jaw line.

Where were his ears! He suddenly felt something twitch on the top of his head and froze, hesitantly reaching up and recoiled when he touched something warm and soft… kitten fur soft. What the hell! He looked at his brother, the things on his head twitched as he heard his brother's heart beat.

"Sam!" He called, panicking as he jumped of the bed and ran towards the mirror in the bathroom and froze at his reflecting, his chest heaving and his eyes wide open.

The soft things on his head where… ears! He stared at the cat looking ears as they twitched, he noticed they were orange and as he turned his head to the side he noticed the black stripes along the back. He stared at the pink insides that had white fur poking out.

"Why do I have T-Tiger ears!" he cried as he stared at the ears that were unmistakably tiger ears and then at the spot normal human ears were supposed to be but like he felt, it was just the ending of his jaw line… no ears at all.

What had happened to him! He froze when he felt something on the bottom on his spine and realised it felt like his spine was longer somehow.

His eyes widened more. He couldn't have… could he? He looked down and saw his fear. A long orange and black striped tail was attached to the bottom of his spine, curling up as it nearly touched the floor. The tip was a pure white colour and he suddenly felt dizzy.

He had a tail… A tail! "Sammy!" he shouted in horror, Sam was hovering in the doorway, looking uncomfortable.

"Hey Dean, I see you woke up" he whispered, glancing at his brothers new tail. They were in for a long and stressful time.
