Theo's Complex
PLEASE COMMENT!!!! I'm desperate. :-(
Also, why exactly there is no "anal vore" tag is beyond me, but the type of vore in this story is that type, so proceed at your own pleasure.
FUN FACT: The main character in this story has Narcissistic Personality Disorder, also known as the God Complex, so I thought it would be cool to name him Theo. 
Enjoy!
Just because Theo fapped at the sight of his own body didn't make him a narcissist. He was just realistic and truthful with himself. He was one of the sexiest creatures alive, and he appreciated that fact by giving one of the sexiest creatures alive (if not the sexiest) a little pleasure now and then. Nothing wrong with that. If anything, people calling him a narcissist were the ones with the real problems. But it was understandable. Not everyone could be blessed with his particular abilities.
His reflection smiled back at him. He flexed his large muscles and stretched his wings. God damn, he was a sexy dragon. His muscles were so big and chiseled. He sported a significant hard-on already, looking at his blue pecs, but he devoted himself to saving that for later. He turned and somehow managed to admire his own ass, a taught, blue pair of cheeks kept hidden beneath a strong rock-crushing tail.
He put on a shirt, changed his mind, and took it off. It was a clear day outside; there was no reason not to please the crowd. He put on a pair of jeans and admired himself in the full-body mirror, creating a bulge in his pants. He rubbed the bulge slightly. He couldn't wait for his meal.
He left his house and drove off in a vehicle. He could fly, of course, but flying created stress for the wings, which caused physical issues, which made him less beautiful, which was unacceptable. He drove about forty-five minutes until he arrived at his destination: a pet shop.
He walked in the door, which gave a little ring-a-ling, signaling the owner he was there. A couple of customers inside looked at him as he walked in, and he made sure to let them notice without giving away too much. Don't be cruel and show them more than they can have, he told himself. He brought his right arm up and scratched his neck, giving off a few-second Michelangelo's David pose for the others to admire before setting his arm down again. They had already stopped looking, obviously not wanting to be caught staring. Theo knew.
He moved directly toward the snake pens, where he'd been many times before. Down in the pens were snakes of all sizes and breeds, but the ones that interested him were the boas.
Most of them were sitting still, hibernating or just sitting there. A couple slowly slithered around their pens. Theo looked at these and picked out the largest one, a biggie about ten feet long and two feet around. He went and found the owner.
"Hey, Theo! You've been working out, as usual," the fox asked.
"Uh-huh."
"Another snake, I guess? Damn, you have the worst luck with snakes of anyone I've ever seen. Do you feed them enough? The biggest ones need more food, you know."
"Oh, they get fed, I promise."
The fox had trouble lifting the snake out of the pen, but Theo lifted it with one arm. He towered over the scrawny fox. The boa was put into a cage and Theo paid the shop owner.
"Try not to let this one die so fast, huh, Theo?" the owner winked.
"I'll do my best," Theo responded. He put the cage containing his next meal in the car and left for home.

Theo let the snake explore a little bit. He lay down on his back on the floor, naked, while the boa glided across his abs and legs. The snake's smooth body brushed against his member. When the snake would try to move away from him, Theo would pick it up by the head and put it back down on his chest. He was careful to keep it away from his neck.
"Gorgeous, aren't I?" he said, half to the snake, half to himself. "And you're gonna make me even more gorgeous. Isn't that great?"
The snake stuck out its tongue in response. Its lidless eyes moved with its head. It was coiled around Theo's right thigh, but it didn't squeeze hard. Theo often wondered if snakes could recognize sapient things like beauty.
The boa squeezed his leg a little harder. Apparently it was as ready to go as Theo was. He giggled.
"Okay, impatient, if you want it so bad. . ."
Theo stood up, the boa still wrapped around his thigh. The snake was heavy, but the dragon had no issue lifting heavy things, and besides, he'd taken heavier snakes before.
Theo took the snake's head gently in his hand, brought it up to his mouth, and licked it. When the snake's head was nice and slick, he raised his tail and carefully positioned the snake at his tailhole. He rubbed the snake's head around and across his love ring, watching himself in the mirror. His hardon was at full throttle, leaking a thin stream of pre. He felt the snake's tongue tickle his entrance, flicking in and out of its mouth.
Theo developed his ability when he hit puberty. At first he simply stopped defecating. His parents thought it was constipation, but it wasn't even that; he simply never had to shit. Then he began developing muscle mass despite never exercising. By the time he was sixteen he was bigger than his father and could lift his mother. He was rarely hungry and sometimes went weeks without a single meal with no problem.
Medical research on his body revealed what caused it all. Normally the body absorbs only what it needs from digested food and expels the rest. But Theo's body was different. It absorbed everything he ate. The food was converted into energy, which was used in his muscles, which caused him to grow, and since his body had more than it needed, he could go long periods without getting hungry. But he soon developed a different kind of hunger, one that wasn't so easily sated.
Once he had experimented with a hamster. Just to see what all the fuss was about, he stuffed it up his ass until it just disappeared. He forgot to clip the nails. His innards were sore for weeks. But moments after the hamster vanished into his nether regions his body was caught in an odd but wonderful feeling, and Theo learned that he could speed up the growing process by eating through the other end.
Slowly he pushed the boa's head in, careful not to squeeze his cheeks too hard. Lubed up with Theo's spit, the snake's slick head glided in easily enough. Theo felt it trying to back out, but he pushed it further in, forcing the snake to go inwards as though he were exploring a new cave in the ground. When the snake was about half a foot in, Theo felt it stop resisting and begin to crawl inwards.
"Mmmf, yeah, explore your new home, baby," Theo said as the snake's long body slowly glided into him, rubbing against his inner walls and pleasuring his g-spot.
The snake continued to move into him. He watched the snake's tail gradually go closer and closer to his tailhole in the mirror. When the snake was about five feet inside him, he stood up straight and posed for himself in the mirror, flexing his muscles. The snake's continuous gliding had Theo's cock wet with pre. He had waited a long time for this. He learned live boas were the best things to eat. Living creatures gave him more energy than dead ones, and boas had plenty of body and energy conserved just for him. Plus, they never bit or clawed or wriggled out of his butt. They were perfect. He bought a new one every month or so, when his urge to grow became too much to resist.
The snake was about eight feet in now. Theo's cock wanted to explode all over the mirror. "Ooh . . . deeper," he urged the snake, "deeper, deeper!"
The snake obeyed, and crawled deeper inside Theo's cave until its tail finally disappeared into his ass. Theo felt his ring close up, but he still felt the snake moving inside him, filling him, moving up to his stomach.
Then he felt it. A sudden deflation, like the snake inside him just disappeared. His body heated up. It was coming.
"Ooh, yeah, make daddy bigger."
The heat spread from his torso to his fingertips. He watched in the mirror. Slowly his body began to expand outwards from his center, and then the process sped up. Every muscle in his body quivered as he assimilated the snake, bulging in veins and bubbling outwards. His cock grew bigger, fatter and harder with every throb, growing to three feet long and two feet across, drooling several gallons of pre down his bulging shaft and balls down to his growing feet.
"More. . ."
It felt so good. Every quiver of his muscles felt like an orgasm. He posed for himself in the mirror, stretching his arms behind his head and watching his pecs grow more and more. His body rumbled and shook as his skeletal structure grew to support the muscles, and every vein on his body pulsed, directing gushes of blood to the growing mass. Sweat beaded and dripped down his neck.
Finally he began to cool down, and the growing slowed to a crawl, and then stopped. He stood there, panting, his body still throbbing, looking at his new physique in the mirror. He had to have been eleven feet tall. His arms and legs bulged with vascular muscles. His cock was massive, four, maybe five feet long, drooling puddles of pre and hard enough to hunt with. His powerful legs were held up by big, strong feet.
He turned around. His back was covered in muscle. His wingspan had stretched from twenty to twenty-seven feet. Even his tail had muscles.
He turned to look at his front again. He posed in many ways, smirking and giving himself seductive grins. He rubbed his chest, his arms, legs, butt, every inch of him; squeezed his hard, pointed nipples, moaning and gasping.
"Oh, yes, oh, God, yes, so much muscle, such a perfect ass, so powerful. . ."
He lay down on the floor in front of the mirror, did some stretches, and brought his knees up to his head. His long, black cock easily came up to his face. He licked the tip, tasting his pre while watching himself in the mirror. He reached around and fingered his sweaty tailhole. He stuck in two, then three fingers, pulling them in and out while he watched the mirror between his legs. He brought his muzzle up and stuffed his hard shaft into his mouth. His bulging testicles rested on his nose, letting him smell his own sweaty scent. He stuffed a fourth finger into his ass.
His cock was throbbing, begging for release. With his right hand Theo pleasured his g-spot; with his left hand he rubbed his muscles, savoring the contours of his body. His balls gently slapped against his nose as he pushed his hand down into his ass, thrusting his cock further down his throat.
Then he felt the clenching pleasure of an approaching orgasm, and swallowed his cock as much as he could. The orgasm approached slowly, blissfully, until finally his massive throbbing meat filled his maw with the hottest, thickest load he ever drank. He swallowed a mouthful and then pulled out, letting his raging member flood his head and chest with white, sticky cum. He rubbed his big balls and fondled his insides as his dick spurted five, six, eight loads all over him. Every time he grew his orgasm was bigger than ever before.
Finally his cumming slowed to several light spurts, then a gentle throb. He looked at himself in the mirror, the massive blue dragon splotched with white. He licked the cum off his lips and let the liquid run down his abs and pecs, pooling on the floor below him.
He stood, stepping into puddles of cum and pre, and kissed his reflection before marveling one more time at the power of his new body.
"And I'm only going to get bigger and stronger," he said to the mirror. "I'll have to find something bigger than snakes soon."
