“I… I can’t sir… uhhhnnn….. p… please Dave… I can’t push it ouuuut.” The pre-teen moaned and whimpered in a mixture of utter pleasure and agony as he begged his torturer to let him push out the massive soccer ball that was now lodged in what was left of his gaped-out asshole. Kyle used to be a typical boy who enjoyed playing sports and doing normal boy things. He was always a good-looking kid, being a young red fox with brown eyes and clean, short hair. No one would have ever expected the cub to be anything more than a typical jock. However, around the age of eight his entire life changed when he met Dusty, his soccer coach. Since then, Kyle has been getting molested on a daily basis. Dusty has been training the cub’s anus to take wider and wider objects and even started fisting the kid at the tender young age of 10. At 12 however, Kyle is now getting the filling of his lifetime. That’s about the time coach introduced Kyle to his new friend Dave. Dave was an incredibly good-looking wolf in his late 30’s. He had dark black fur, muscles made of steel, abs that looked as if they could murder someone just by staring at them, and fierce brown eyes that made Kyle’s little dick twitch the moment they locked with his own.

  	Kyle had actually met Dave previously through his friend Marty, but he had no idea Dave was into such sadistic and, (fortunately for Kyle,) such sexually explicit adventures. This led to Kyle’s predicament of having a soccer ball shoved into his asshole and fully inflated. The soccer ball started out uninflated after a long fisting session that led to Kyle having plenty of dry orgasms. But as soon as the soccer ball was fully lodged in his ass, the inflation began. Kyle moaned and writhed in both pleasure and pain as his entire pelvic region and lower abdomen became fuller and fuller. He had never felt such complete fullness in his entire life and he felt as if his lower half was going to explode from the sheer pressure. His legs spread as he arched his butt into the air and his tail raised while he tried his best to push the massive growing object out of his butt. But it was to no avail.

  	 Dave kept a firm paw directly on his butthole to prevent the ball from being pushed out and to prevent the needle that inflated the ball from missing its mark. “Dave!... D…Dave… I can’t take anymore! Please! I’m too full!” Kyle squealed as his groin began to bulge out from the sheer size of the ball. “Shut up kid… you wanted this and it’s too late to back out now. I know it hurts but you’ll get to use do the size in no time buddy.” Dave responded with little empathy. He knew the cub was just complaining from the feeling and that he wasn’t actually hurting the young tyke. Besides, he was enjoying hearing the kid whimper and moan in pain and pleasure. He wasn’t about to stop now regardless, it was turning him on like never before to witness the boy’s asshole literally bulge and puff out as the ball started to fill Kyle up to the extreme. By this point the pressure was smashing the kid’s prostate to oblivion and his groin area was beginning to look abnormally pregnant from the ball bulging his cock and balls out. Kyle moaned one last time and collapsed his head on the bed as his mind was lost in the feeling of complete and utter fullness.

	The sound of puffing air from Dave inflating the ball soon became the most noticeable sound throughout the room as Kyle grew increasingly quieter due to his mind getting lost in the overwhelming sensation of being completely full. His asshole was now stretched beyond recognition as everything from between his widely spread butt cheeks to the base of his cock was bulged out like he was about to give birth. With one last puff of air, Dave pulled the needle out of the ball and grinned at what his eyes saw. Kyle was bulging enormous between his legs and his cock was arched unnaturally toward his chin and pressed directly against his belly due to the sheer pressure the ball was putting on his little dick. The pup’s balls, tight and tout, were separated from one another and his taint obscenely pushed out from between them. It was the kid’s ass that made Dave grin the most however. Kyle’s ass cheeks were spread widely apart from one another and his entire crevice was now round, bulging and pushed out with obscenely stretched, pink, puffy ass lips surrounding the only part of the ball that was still visible. The cub was so full that his sphincter couldn’t close all the way around the ball and was spread at least 4 ½ inches in diameter. “That’s a gooood boy Kyle! Good boy… Feels good doesn’t it kiddo?” He grinned sadistically down at the cub who could only drool on the floor with his ass arched up, tail hiked and legs spread wide, unable to close. Kyle couldn’t even answer back, he was lost in the feelings of absolute fullness and incredible pleasure. The pain was mostly gone now, all that was left was an immense urge to push as hard as he could and the indescribable, pleasurable sensation of being absolutely full beyond imagination right in his undeveloped, underage butthole.

	Dave started to scratch the top of Kyle’s head to try and get the kid to relax and also to see if Kyle was still responsive to any outside sensations. There wasn’t any response however; Kyle was simply too lost in the extreme feelings. “I think I’ll just leave you like this for a while pup… let your ass get used to being this full. Just keep pushing buddy… it’ll pop out eventually.” At that he left Kyle in that position on the floor and walked over to the corner of room where another boy was patiently waiting. This was Marty, Kyle’s best friend from school. He was a Marten (close to a weasel but way cuter). He had brown eyes, light brown fur, raccoon mask colorings on his face, and was truly an adorable kid. Marty and Kyle met during soccer practice when they were nine. They didn’t always get along. Kyle used to bully Marty and even once gave him a black eye. That all changed one day however when Marty returned to the locker room to pick up something he had left behind and found Kyle getting his sweaty, musky, after practice asshole eaten out by coach Dusty. Marty at first kept this secret to himself considering Dave had been doing nearly the same thing to him for years. However, the next time Kyle decided to beat Marty up, he let it out that he knew exactly what him and coach were doing. Kyle’s face turned red with shock and embarrassment and begged Marty to never tell anyone. Marty held this over Kyle for a while but eventually, with Kyle being a lot nicer to Marty, the two started to experiment together and that led to the eventual meet up of Dusty and Dave. Kyle wasn’t aware that Dusty agreed to let Dave destroy his asshole until it was a bit too late… not that his butt wasn’t already ruined from coach’s daily fisting sessions.

	Marty looked up at Dave with terror. Unlike Kyle, Marty was scared to death of Dave for very good reasons. Dave has never really been easy on Marty with his anal training and has always been a lot more sadistic than Dusty had ever been on Kyle. Marty gulped as Dave stared down at him with an evil smirk on his face. “Don’t worry Marty… that’ll be you next. For now, though… let’s get you loosened up.” He reached down and grabbed Marty by his scruff and pushed him toward the bed in the center of the room. Kyle was still drooling on the floor in front of the bed with his ass in the air and his legs spread as wide as he possibly could. The bulge was likely making it difficult for him to close his legs in any way. The wolf pushed the little twelve-year-old onto the bed face first and then lazily climbed onto it until he was over the boy, his breath blowing down the kid’s neck. “You better be a good boy and like this as much as Kyle did. Don’t pretend you can’t take it like him.” He spread his legs on either side of Marty’s rear and used his paws to lift the boy’s ass up toward his achingly hard dick. In comparison to Marty or Kyle, Dave had a massive cock. His knot was the almost the size of their heads and his length was enough to cause some serious damage if he weren’t skilled enough and careful enough to know how to properly use his weapon of mass destruction on their young holes. Fortunately for Marty, he had already been heavily fisted just as much as Kyle had and this isn’t the first time Marty had been fucked by Dave... not to mention Marty was already fairly lubed and loosened up from prior fisting that day.

	Without hesitation, Dave sunk his cock all the way to the top of the knot with the only resistance being Dave’s knot hitting the pup’s entrance. Marty yelled out due to how quick Dave pushed himself into him but had little time to react before the big wolf pulled his dick all the way out and shoved it in once again. Tears streamed out of Marty’s eyes as he was caught between a mixture of pain and pleasure. Dave wasn’t gentle by any means and began to viciously pound at the Marten’s already gaped out asshole. “Fuck yeah Marty, push back against me… I said fucking push kid!” He screamed at the kid as he ground his dick as far as it would go without the knot popping in before once again pulling it all the way out. With a sloppy wet plop, Dave’s dick popped out of the boy’s ass followed by a loud fart as his asshole prolapsed from the immense anal play. “Fuck yeah! Push that prolapse out again boy!” The kid still had tears going down his cheeks as he tried his best to follow through with Dave’s command. He knew better than to refuse Dave his pleasure. Another wet fart sounded throughout the room as the kid’s asshole once again prolapsed as Marty pushed as hard as he could. “Ohhhh fuuuuck yeah… Fuck yeah!” Dave shoved his entire dick back into the prolapsed ass, shoving the prolapse back in as he hilted the kid once more. This made Marty gasp and moan from the immense sensation of having his ass shoved back into him and then fucked again.

	Dave’s hands explored the underside of Marty until a paw reached the boy’s erect 3 ½ inch dick. He grasped it and moved his grinning, panting mouth next to Marty’s ear. “Yeah boy… you like it when you’re fucked by a man don’t ya?” He pulled out once again and shoved his length all the way back in and continued to do so with each thrust. “You like having a big fat dick up your little butt, don’t you? Yeah fucking taking it boy… fuck yeah I’m going to cum in your ass!” Dave started manically thrusting in and out of the kid, making Marty literally lift off the bed each time the dick pulled out and thrust him back into the bed with each hump. The twelve-year-old couldn’t stop moaning and crying. He was obviously loving the feeling but it was overwhelming for his young mind. Just as he thought it couldn’t get any worse, the thrusting ended with one more hilt and Dave grabbed onto Marty’s shoulders and pushed him as close to his cock as possible. Marty felt his asshole spreading wider and wider and his mouth dropped open in a silent scream as something the size of his head slowly filled up his rectum. With one final push, the massive knot popped into the kid’s blown out asshole and smashed the pup’s prostate. The kid squirmed under Dave, kicked his feet and trying to pull off of the massive knot but Dave held him down as he began to cum inside of Marty. The little marten continued a silent scream, only managing to let out a small whimper or two as he started to piss himself from the intense pleasure of having such a massive dick fuck him.

	“ohhh yeah… good boy Marty… oh fuck.” Dave finally began to relax as his cock slowly stopped squirting into the boy’s bowls. He felt how wet his hand was and knew that Marty had pissed himself but it didn’t bother him at all since it came with intense anal play. Dave kissed the boy’s neck lightly before he got up and pulled away from the kid. The pup’s ass was lifted up until the kid was hanging from the knot as Dave stood up before the massive knot finally popped out of Marty’s bruised asshole at full size. With that, an enormous, pink prolapse pushed out of his butt with a loud wet fart once again. This time however, cum poured out from his abused hole at the same time. Marty laid on his stomach, his legs spread, tail covering his gaping and abused butthole as he tried to regain the energy lost from the massive fucking he just received. Dave walked over to Kyle and squatted down so his cock was right in front of the kid’s nose. “Yeah… you smell that buddy? That’s your friend’s ass. I’ll have you suck my dick clean next time when you are so phased out.” He looked around to the raised backside of the pup and looked at his ballooned-out asshole. “Heh… looks like it’s going to be quite a few hours before you can finally push that out little dude. I’ll let you just rest here feeling nice and full while Marty rests. Your coach should be back soon.” With that, Dave left the room, locking the door behind him to prevent any of the cubs from escaping, not that they had the energy to do so.
