"Don't worry, I can do it by myself!" The lion cub said confidently. "Okay then, sweetheart, I'll see you this afternoon if I get out on time." She rummaged through her purse, handed a few bills to her boy, then pattet his cheek affectionately. "Just in case I have to work a double shift. Order yourself a pizza, okay? That's a good boy." She drove away, leaving the cub to walk into the medical clinic by himself. His mom had already checked him in on her cellular, and the attendant behind the counter verified he was there. He played some games on his phone while he waited, and unfortunately he had to sit in the lobby for over an hour; his mom had needed to drop him off early in order to get to work on time. He didn't live too far from the clinic though, so he could walk home easisly - he sure hoped his mom had to work late tonight, so he could order that pizza! When he finally got called back to start his appointment, he entered the room and sat patiently for another twenty minutes before the doctor arrived. "Sorry for the wait, young man!" The large bull said, carefully maneuvering his horns around so that they didn't damage anything. He looked very well-built, and his uniform fit him very tightly. The lion cub tried not to stare - the large bull was sporting a huge bulge in the front of his pants. He'd heard about this sort of thing, some men just naturally had gigantic genitals sometimes, and had to wear special underwear to hold them. "And I assume," the doctor said, "that you're Brandon? May I call you Bran?" he asked as he prepared some paperwork. "Yes, Doctor," the boy said politely. The Doctor eyed the cub over his clipboard; he was a scrawny little thing, much skinnier than the hulking, over-masculine bull preferred. In other circumstances such a thing could be dealt with, but he couldn't always risk the quick methods. The lion cub had scruffy, messy hair, which would stay until his mane grew in properly. He wore a blue t-shirt and denim shorts, held up with a belt because he was so thin. Oh, if only the bull could have his way with the cub, he'd be able to sort that out himself.... "Say, Brandon," the Doctor asked nonchalantly, "Where's your mom at, sport?" "Oh, I told her I can do my appointment by myself! I'm almost twelve now, I'm a big boy!" "I see," the Doctor said with an affected chuckle. "So you've left her in the lobby, huh?" "Well, nooo," Brandon admitted. "She dropped me off. She has lots to do at work, and I can just walk home when I'm done here." "Oooh," the bull said, not quite able to hide his interest now. The boy might just be a good candidate for his... preferred sort of medical intervention after all. "How late will she be? Surely she won't leave you by yourself for too long, right?" The lion boy just shrugged as the bull began the exam, starting with temperature and listening to the cub's breathing. "Oh, sometimes she works two shifts. She left me money for pizza just in case!" "I see," the Doctor said, getting more and more excited. "Will she be working late tonight then?" "She'll text me if she has to!" The doctor continued the examination, recording the boy's pulse and blood pressure, testing his reflexes, and looking into his ear canals. He did every little test he could think of, trying to buy for time and hoping that the cub's mother would text. And then finally, as he was just giving up hope, she did. "Oh well," Brandon said. "Looks like it's pizza time for me!" He said with enthusiasm. The bull chuckled, wrapping up the paperwork. "You gonna eat that entire pizza yourself, Bran?" "Oh gosh, no," the little lion laughed. "One slice is enough. Sometimes I try for two, and I can never finish it!" "Oh, I see," the Doctor said, feigning worry. "I should check that, then." "Is something wrong, Doctor?" the boy asked, uncertain now. "Well, a little boy really should be able to eat an entire pizza all by himself, you see." "Really?" "Yes, Brandon. I've personally seen little boys your age eat two or three in one sitting!" "Oh gosh." "I'll just check your belly real quick, okay buddy?" The doctor gently pressed the lion cub down so that he was lying on the checkup bed, then instructed the boy to spread his arms and legs out. The bull then strapped the cub's wrists and ankles down with soft restraints. "Don't worry one little bit, Brandon, I'm gonna fix you right up. "Is this gonna hurt, Doc?" Brandons asked, his eyes going wide as the doctor prepared a needle. "It'll just be a tiny pinch," the bull said as he carefully injected the boy. It was a concoction that would greatly speed the boy's digestion and metabolism, and contained a powerful anti-emetic to stop the boy vomiting. "And then you'll feel really, very full. Fuller than you've ever felt in your entire life." "T-the shot does all of that?" The boy asked, whimpering slightly. "Oh, no. No, Brandon. THIS is going to do all of that." The Doctor pulled a large hose from the ceiling, as thick as his wrist with a bitable attachment at the end. "This hose is connected to a massive tank filled with high-calorie nutrient material. Like a milkshake, sort of." The bull was preparing a restraint and attaching it to the hose. "W-what are you going to do with that, Doctor?" "I'm going to put it in your mouth, Brandon, and it'll stretch that belly of yours out real good. You'll be scarfing down whole pizzas one after the other by the time I'm through with you!" The boy tried to shout, to scream, but the Bull clamped a large hand over his mouth, then shoved a metallic mouth-spreader into the boy's maw, which served to hold his jaws apart. Then the bull slipped the head-restraint over the boy's face, tightened it down, and began to slowly push the hose past the lion cub's lips and down his throat. Brandon's eys spread wide, and he made some choking sounds; but nothing happened. He gagged a little, but nothing came up. He looked at the bull in disbelief as the hose finally slithered to a rest directly in his stomach. "Dinner time, Brandon. You'll be drinking every drop." Then the doctor turned on the pump, and gently rubbed the lion's meager little tummy; he watched as the fluid began to flow through the hose, and the lion cub's eyes grew even wider. He smirked, then turned and locked the door behind him as he left. Brandon's belly filled very quickly, until it was completely full. Then it filled even more, the fattening fluid continuing to flow into him. His belly began to bloat and swell until it pushed upward past his pants, his shirt slowly sliding up the growing dome of his gut. He whimpered into the hose as it filled him more and more. When his belly was as huge as a pregnant woman's he began to wonder if it would ever stop, if he would ever be free of this thing. When his belly loomed massively above him, sagging over the sides of the examination table and covering his legs up, all he could do was wonder just how huge he was going to get. The doctor returned at midnight, after all of the other staff had gone home. When he opened the door he found that the lion cub he'd met that morning was now a moaning pile of boy-bluber. The concoction had worked - the boy had guzzled down gallons upon gallons of fattening slop, and had actually digested every last drop of it. He was massive, well over a thousand pounds, His huge soft belly wobbling gently as he grunted into the hose, trying to get the Doctor's attention. "Oooh, you poor thing. You must be starving!" The Doctor said as he removed the boy's head restraint; he tugged on the hose, which slipped up and out of the boy's throat until the very end came free. "BRRRRAAAAAAAP!" The cub belched and belched massive explosions of grumbling burps until he was left panting for breath, his fat boy-tits heaving up and down. The boy's belly sagged massively down both sides of the examination table, and drooped over the front end. His arms and legs were buried in big, quasi-spherical masses of lard, his fingers wiggling uselessly. "Doooctor," he wheezed. "Doctoooor, I'm huuuungry!" The Bull stared in awe at the massive, bloated mountain of boy-fat heaving before him on his examination table. He ignored the boy's begging cries entirely, his eyes traveling from one enticing feature to the next; huge pancake nipples, cheeks like wobbling cantaloupe, the belly like a massive beanbag chair of taut, smooth, wobbling cub-lard. And the cub was covered in sweat, positively soaking in it. But what he wanted most, what he needed, was still obscured. As the bull's enormous cock stiffened, forming a tent four feet long in front of his hips, he walked around the examination table and sunk both hands into the boy's lusciously fat side. Then he pushed with everything he had, the boy tipping and then slowly rolling over the side like an avalanche of jello. Brandon yelped as he hit the floor, then groaned as his starving belly growled beneath him. The bull stood in wonder, staring at the cub's rump in pure awe. The boy's ass was glorious, two heaping piles of symmetrical fat with a tube of fat cub tail resting between them; he shoved that tail aside, absently hearing his trousers tear as his bovid cock grew to full length. He tore the remaining scraps of pants from his legs, his enormous balls swaying before him and pressing heavily against his thighs as he stood in a wide stance. "Doctooooor," the previously little lion cub was saying, but the bull paid him no mind. His blood was up, he was seeing red, and his cock twitched a full foot upward, raring to go. He could restrain himself no longer, and he roughly aligned his splayed, flaring head between the boy's undoubtedly virgin rump cheeks. Brandon squealed loudly as he shoved himself inside, the boy gripping him like a velvety vice; his nostrils flared and his heart raced as he shoved even harder, met more resistance, and shoved even harder still. When he felt his hips touch boyflesh he began to thrust in earnest, holding nothing back, plowing the fat boy's ass with everything he had. The sound of his breeding filled the room, rough slaps of his hips against Brandon's backside mingled with the boy's mewling cries - they drove him on, his hands grabbing fistfulls of soft boy fat as he hammered his hips home, his humongous nuts bouncing off the boy's ass and swinging like a pair of wrecking balls. It felt like an eternity, but it could only have been a few minutes of mind-blowing breeding before he felt those massive orbs clench, and the bull screamed aloud as they began to empty, expanding his eurethra like a firehose. As he pulled out, gallons of bull cum splattered onto the boy's wide, wobbling ass. The bull collapsed onto the whimpering pile of fat which had once been a lithe and cheerful lion cub. They panted together, struggling for breath, one because he was enormously obese and the other because he'd just had the greatest sex of his life. "Doctor?" Brandon asked quietly. The bull hesitated for several seconds, his hands wandering under the cub's fat arms to fondle his boy-breasts. "Yes, Brandon?" "I'm ready for my pizza now, please."
