Author’s Note: This story has surgery to make the cub incontinent permanently.  It is well surgical… minimal description and minimal pain.  I really wasn’t sure what to tag it to make that clear and I want to make sure no one ends up reading something they don’t want to read.
---------------------------------------------------------------------------------

The wolf drove for a while the cub gasping at every bump as it pushed and moved the plug deep inside him eventually stopping at the wolf's lair deep in the forest.
“Uhhh can you take all this stuff off me…” said the lion who during the car ride had finally stopped crying for the most part.  
“Hmmm well I guess we can take this out,” said the wolf pulling the rear of his diaper down enough to pull the plug out making the cub gasp and cry a bit as it pulled out of his rear.
“And the rest,” he said hopefully.
“No the rest will be staying on,” said the wolf much to the cub’s disappointment.
The wolf then locked the lion in a room and left him for the night to sleep as best his tortured and padded soaky rear would let him.  He hemmed and hawed over taking off the yellow swimsuit eventually deciding he didn’t want to be in a girl’s bathing suit even if it did mean his soaky bum was shown off. He tentatively touched the catheter and tugged on it a bit, but the pain warned him that it would not be a good idea to try to take it out.  He would have taken the diaper off, but even though it was super embarrassing he was smart enough to know if he couldn’t get the catheter out taking the diaper off would be a bad idea.  The lock he had been forced to put on the cock cage meant that wasn’t coming off either.  The lion pretty much collapsed from exhaustion once he had himself all set on the bed.
The next morning the cub woke up to a cock in his face and his diaper soaking wet from the catheter causing him to burst out crying, but the wolf just smiled without saying anything. In the corner the camera had been set up as well.  The lion tried to turn away, but without saying anything the wolf forced his head back to face the cock.
“Nooo please…” said the lion begging, but the wolf just kept his cock in front of the cub.  Eventually reluctantly without being asked the lion desperate to get the smelly cock out of his face started to lick it to an encouraging smile from the wolf. Finally after realizing it still wasn’t going away and remembering the day before he put the cock into his maw.
“Atta boy sucks cock without even being asked in his soakies,” the wolf said with a grin as he started to thrust into the cub’s maw as the talk made the boy go bright red on the cock.  The little cub was forced to keep sucking as the wolf began to moan gently encouraging the boy.  Finally after making the cub suck him for almost 15 minutes the wolf felt himself about to cum and put his hand on the back of the cub’s head and as it started to squirt hot sticky cum into the cub’s maw. While the cub had heard of cum and indeed had his rear filled with it the day before he hadn’t quite comprehended exactly what the squirting feeling he had felt in his rear and later had to lick.  Thus it came as a surprise as his maw was filled with the hot sticky cum and he instinctively tried to pull off, but the wolf held him tight as his milk went into the cub.
“Awww atta boy… the big lion leader needs his protein,” said the wolf with a big smirk gasping as he filled the lion’s maw with multiple globs of cum slipping into the cub’s throat.
“Now swallow for the camera,” he said making the gasping confused cub as he got his first taste of real cum aside from the bit he had been made to lick earlier frown as he realized he was being filmed again just like the day before. The cub instinctively tried to spit it out, but the wolf grabbed his maw and trapped him.  Finally after sitting there for a bit with the sticky salty cum in his maw he gave a gulp.
“There ya go got your tasty treat,” said the wolf with a grin.
“Please let me go…” the cub said still gasping and crying.
“You can go in a few weeks when I am all done with you,” said the wolf with a grin squeezing the boy’s caged and cathed diaper front thinking about his plans for the lion who currently looked more like a wolf cub.
“Uhhh can I get this off me at least…” said the boy indicating the catheter.
“Nope can’t have you thinking you dun need the diaper,” said the wolf with a grin as his cock went down dripping a bit more cum.
“Uhhh…” said the cub thinking desperately… “Could I at least have a change…” he said smelling the diaper.
“Hmmm,” said the wolf slipping a paw into the crotch and rubbing the inside of the diaper, “Nope ya still got plenty of padding left,” he had made the diaper really thick the day before.
The wolf let the boy hang out for much of the day watching Cub Rangers and other fun shows on TV.  Obviously the cub was not allowed to play on the internet.  He was mostly thankful that his rear wasn’t full.
Later that day as it was getting late the wolf switched the tv and the cub suddenly found himself watching the film of himself from the day before.  He tried to go away, but he found the wolf there forcing him to sit back down and keep watching it.
“Please… I don’t want to watch this…” said the lion cub.
“Well would you prefer to act it out again then?” asked the wolf with a grin.
With that the cub shut up figuring it would be better to watch this than have his bum taken again.  By now his diaper was getting quite squishy as he watched his virginity taken in rape and later winced as he got a good view of the cath going into him.
As the show ended with his diaper being peed in the little lion felt his diaper rear being pulled down.
“Now that you have seen what you did it is time to try again,” said the wolf with a grin much to the lion’s dismay.
“But you said if I watched it you wouldn’t…” he protested.
“Well now it is over I only said I wouldn’ while you watched it,” said the wolf, “Now yesterday ya didn’t have so much fun… I think it is time you learned how to treat your boyfriend so you dun get hurt… as much at least,” he said with a laugh handing the boy a tube of lube.
“Uhh…” he said opening it and rubbing it a bit as he realized what it was.
“Of course if you wanna go without it again,” the wolf said making the cub remember the pain in his tailhole he quickly got a big glob on his paw and unzipped the wolf’s bulging pants revealing his cock and began to rub some lube onto it.
“Heh atta boy do everything to get the thick cock ready,” the wolf said with a smile as the cub was desperate enough to make it not feel like it had last time he lost some of his shyness around the cock accepting that the cock was going to be going into him and trying to make it better.
After the cub put the lube on his cock the wolf wrapped the boy in a strong embrace and began to kiss him.  As he kissed him he worked some lube onto his paw and slipped it into the diaper and began to work the finger into the cub’s bum.
“Ya might want this kiss to last for a while,” said the wolf with a grin as the cub realized that while he kissed his rear would get lubed more so he submitted and kept kissing the wolf though he did start sobbing a bit as the finger worked it’s way into his mostly recovered though still sensitive rear.  Finally though the cub couldn’t keep it up any more and the cub pulled away.
“Guess we’re all ready now,” said the wolf with a grin as he laid the cub on his back and pulled down the squishy diaper rear and put his cock at the entrance and started to push in.
“Please go slow…” begged the lion right as he gasped as the whole cock was pushed into him with a single long thrust.
“This is as slow as you are going to get,” said the wolf with a grin as he started to pull out enjoying the cub’s tight rear as the cub watched it over his soaky diaper crotch dribbling as the cath emptied into his diaper.
Slowly the wolf humped up and down in and out of his rear.  This time the cub was not as panicked and with the lube it didn’t hurt nearly as much.
“Mmmm ya feel that dun ya?” asked the wolf with a grin as the cub gasped with the cock rubbing his rear deep inside.
The wolf kept thrusting in and out of the young cub getting him looser and looser as he took the adult cock in his lil cub rear for the second time.  Eventually as the wolf went slow and more gently his rear started hurting.  Of course this didn’t help much because as it stopped hurting his peepee started trying to get erect and the combo of the cath and cage meant that was very painful.  Thus as the cub was fucked he was left gasping in both pleasure and pain.  All he could do was stare as he felt the cock thrusting in and out of him.  Suddenly the wolf sped up making the cub gasp more as his rear was taken and then suddenly with a loud moan the wolf shot a thick load of cum deep inside the cub making him moan a bit before it was cut off as the cage and cath kicked back in.  The cub was forced to stay there as load after load of cum shot into his bum filling it.  Finally the wolf pulled out leaving the cub dripping cum from his rear into the diaper. The wolf left the boy gasping as he went and got a nice thick set of anal beads.
“Now put these in…” said the wolf with a grin holding them up.  Reluctantly the cub put them in though it wasn’t very hard given how loose he was now and thus the cub was left in very soaked diapers he had been wearing now for 24 hours and a filled rear.  Later that night after he had sat in the cummy soaked diaper for a bit longer he finally got a change.
The next day the lion said, “This uhhh tube thing in my peepee… it is hurting… please can you take it out… I’ll even keep using the diaper,” he said with a blush figuring that was his best shot to get rid of it even though the only time it hurt was when he tried to get pokey he just did not like the idea of a tube in his cock.
“Hmmm yes I think we can do something about that,” said the wolf with a grin.  With that the lion felt himself strapped into the changing table and with a mask put on him he got sleepy. When the cub woke up the next day he was relieved to find that the tube in his cock was gone though the cage was still on him. His crotch felt a bit weird, but nothing painful.  Much to his surprise as he got up he suddenly felt his diaper getting warm and trying to stop it had no effect.
“What… what did you do to me?” he asked.
“Well now since you didn’t like the cath we did a little bit of surgery… now a few nerves cut and now lil lion can’t hold his peepee even without the cath,” said the wolf much to the cub’s dismay.
“How long does it last?” the wolf said desperately hoping it might be temporary.
“Awww you won’t be potty trained ever again with this,” said the wolf with a grin as he unzipped his shorts for a BJ.  Luckily for the cub he had some mercy and only had him give a BJ that day.  Of course as the cub did his penis leaked all through it slowly making his diaper get wetter and wetter even as he gave a BJ.  Over the day the cub experimented desperately trying to hold it in, but all he managed was to be able to tell when he was wetting as his diaper got soakier.
He got the next day off and the wolf didn’t even have him give a BJ.  Of course this was also so that the next day the wolf would have lots and lots of cum.  Unfortunately for the cub he did get a super thick diaper.  Much to his dismay the wolf started to again use his diaper.
“Nooo please use the potty,” said the lion cub as the warm stream went down his rear soaking his extra thick diaper.
“I am using the potty,” said the wolf with a grin.
“Uhhh can I please have a change…” the cub begged that day when his legs were spread wide open as his diaper expanded getting wetter and wetter both from himself and the wolf using him.
“Nope ya can’t… but you can have a cock,” said the wolf with a grin as he lifted the little cub into his lap, “Now take it out and get it ready,” thus the little cub was forced to unzip his pants and start licking it as the wolf squeezed his diaper making pee run down his rear as he was on his hands and knees taking the rapidly growing cock into his maw..
“You are getting good at this boy turn you into a proper cub cocksucker,” laughed the wolf as he pulled the boy off his cock a line of precum going from the lion’s maw to his cock.
“Now I think it is time for you to learn about doggystyle,” said the wolf with a grin as he forced the cub down on his 4 paws and lifted his tail pulling down the diaper.
With that putting a bit of lube to add to the cub’s spit he wraped his arms around the cub getting on his own knees and started to push his cock into the cub.
The cub instinctually struggled to get away, but the doggy style position left him unable to do much more than wiggle and struggle futilely as the cock worked it’s way deep into his rear.
“Mmmm I love a tight cub,” said the wolf as he cock slipped all the way into the cub, “I wonder how long you will still be tight for,” he said with a distressing laugh.
All the cub could do was gasp as his rear was taken for the first time after his surgery as the thick diaper kept his legs nice and spread for the humping.  As before at first the humping hurt, but soon he was loosened up and instead it was his cock trying to get pokey that hurt as it hit the cage still dripping pee as his newly nonfunctioning bladder continued to leak even as he was humped.  Thus he was again left gasping and moaning as the pain and pleasure rotated of course it was just pure pleasure for the wolf as he pushed in and out of the cub enjoying his gasps and struggles as he tried to get away from the invader even as it rubbed against his prostate.
Finally the cub felt the cock in his rear speed up as he ceased struggling and gave in trying desperately to not get excited causing pain.  Then the stream of cum hit him deep inside coating his insides with the cum and the cage clamped down tight as he tried to get erect again from the stimulation on his rear as the sticky globs hit his prostate.  The wolf held him tight until he had shot all his cum into the boy.  Instead of pulling out though once the cum was done the wolf simply started peeing in his rear the softening cock letting it escape out the cub’s rear and run down into the diaper. Finally the wolf pulled out and smiled as the lion’s rear leaked cum and pee as it slowly closed back up and he finally pulled the cub’s diaper back up.
The cub lay there gasping before saying hopefully, “Uhhh new diaper now?”
“Hmmm yesh you can have a new diaper,” said the wolf with a condescending smile.
He picked the cub up and put him on a changing table only instead of changing the diaper he positioned a new diaper a few sizes too big along with a few more soakers under the cub and then took a pinwheel and ran it up and down the cub’s diaper still on him before taping up the new diaper over the old one.
“There now you got a new diaper,” said the wolf.
“Nooo that isn’t what I meant,” the boy pouted uncomfortably in the new even thicker diaper still squishy as he was made to go to bed.
