[Multi-Tit Growth, Dog Cock, Reality Shift, CBT]

Izuku always thought that he didn't have a Quirk. The fact that he didn't have one was a cause of much of his young life turning gradually sour as his friends grew distant from him, bullying him because of his lack of one. It was only as he grew older and gained One for All through the chance meeting with All Might that he got the chance to turn things around.

But as it turned out, he did have a Quirk. He was just an incredibly late bloomer. At least, that's the only way one could really describe the way that he suddenly woke up to three rows of tits hanging off his body, his form reaching out over the frame of his bed, and the enormous dog-shaped cock hanging between his thighs. To say that he was astonished once he woke up was an understatement. In fact, the sheer shock of it all made him unintentionally ram his red rod straight in between those rows of tits, which caused him to thrust until he had cum so much that the floor had been covered in his absolutely horrendously sticky seed.

To make matters worse, as his Mom came to check on him, she didn't seem too bothered. Just happily telling him that he was going to be late for school if he kept on blowing his load so early like this. Even though his form was now more than feminine, she still treated him like a boy. Which was probably because there was no slit underneath his balls, something that he only found out after having to fondle his nuts in the middle of his unintentional masturbation session.

He didn't actually make it on time. He only just managed to arrive at school as Gym rolled around, where both the teachers and the female students just gave him a pass. They knew that he'd be like this, that was just the side effect of his Quirk. And since he had done a lot for the city thus far with the other Quirk, he had earned a couple of free incidents like these.

Even just hearing their voices was too much for him, as he almost squirted right on the girls' faces when they looked at him and complimented that he was bigger than before. They downplayed his accident, because he had done so much to help them, even if they were starting to grow nice and horny in his presence.

For their sake, he just hoped that he would be able to contain it. That's what he hoped, as he headed to the Boys' Showers...

"You're late, Dicku! Goddamn, I know you've got that Red Rocket between your thighs, but you could be on time!"

Izuku blinked a little as he heard Bakugou's voice ring through his ears, causing his cock to tremble a little bit more. He was sensitive to anybody's voice, it seemed. Not just those that were gentle towards him. "D-Dicku? K-Kacchan, what do you-"

"Don't you start acting like you don't recognize that name!" Bakugou shouted as he stomped towards the oversized pup, grabbing ahold of his fat tits to make sure that he understood just how frustrated he was. "You've had that thing since you were a damn kid, and you never got embarrassed over the nickname before, don't you dare act like you care now!"

"You should refrain from manhandling Izuku too much." The cool-headed Todoroki muttered, all while keeping his gaze completely off the scene. Even if the smell of Izuku's pheromones was making him get nice and hard. It was something that he and the others in the class had gotten used to.

Even if none of this was supposed to be this way. "S-Seriously, K-Kacchan, t-there has to be a mistake! T-Todoroki, y-you know that I wasn't like this yesterday, right?" Izuku did his very best to try and appeal to their memories, all while his cock was squeezed between those manhandled tits. Feeling Bakugou's hands dig into his dog tits was so good. It was making it harder and harder for him to think straight. Not that he was able to think straight since the moment that he woke up...

"Yesterday..." Todoroki paused, his cock growing a little more erect as he looked away. "I'd rather not talk about what happened yesterday." The usually cool-headed boy muttered, as if something incredibly intimate had happened. Even though it definitely hadn't!

"Quit trying to change the subject, Dicku! You're late, you have to apologize!" The angry blonde cried out as he gave each row of tits an appropriately hard slap, causing the rows to jiggle and slap up against the dog dicked boy as he lowered his hands a little more to slap and clap his hands against those enormous balls. "How the hell can you be late when these things keep you up all night?! You barely even get to sleep when you're this big!"

Izuku didn't know what to say, nor how he should try to argue his way out of this. All he could do was just squirm and gasp and squirt as the cum rushed out of his abused balls and straight into the ceiling thanks to the powerful orgasm that just rushed through him. He couldn't even stay on his feet, gasping and groaning as he was forced to sit down and squeeze his legs together which caused his balls even more pain so everything just kept repeating while he sat down.

"God, he just never stops! Why can't he go bathe with the girls anyway, he looks just like one! So what if he doesn't have a cunt, he's as sensitive as they are!" Bakugou shouted in frustration, very nearly stomping his foot onto that sensitive set of nuts before just idly applying pressure. Almost as if he had some level of restraint for his old friend with that big red cock that had given him so much entertainment as a kid. Seeing him consumed by his own shaft... Heh, those were the times.

"You kiddin'? If we throw Dicku into the Girls' Showers, they'll end up knocked up and unable to walk for months! I know you loved the time it happened when you were both kids, Bakugou, but we kinda need them." Kirishima said, stretching a bit as he had to temper his friend's incredible anger. "Just let him wash himself and then we won't have to worry about his smell for a while. You can help him if you want, that way-"

"Like hell I'm cleaning a dog like him!" Bakugou cut his redheaded friend off, properly stomping on the pupper's balls in the process and forcing another potent cry of pure pleasure to rush out from his lips. "He can clean himself. Just thinking about washing him is enough to make me gag. You wash him if you want!" The blonde shouted as he headed towards the other end of the showers, so he could get as far away from Dicku as possible...

Not that it was hard to get away from Izuku. Getting up after an orgasm, even one caused by his balls being pleasurably busted and driving him into a loop of constant orgasms. Just thinking about orgasming was making more of his cum bubble right out of his shaft, like he didn't have a choice in the matter.

"Heh, looks like Bakugou's been a bit rough with the goods. But that's alright, ain't it, Dicku?"

Mineta was the only one that bothered trying to approach the dog-dicked version of the former star student, all while climbing onto his torso like it was nothing. Hell, he was letting his bubbly butt sit right on top of that cock, like it was nothing dangerous or anything. All while his own pheromones started to waft through the air...

Pheromones that pulled Izuku out of his stupor of pleasure and into a completely new haze, one focused around the grape-wielding boy that now sat dominantly on top of his cock, all while his own massive schlong pointed right at his face. A cock that wasn't as big, but definitely overwhelming nonetheless...

Izuku wanted to say something. But his mouth was doing everything in its power to ignore what he was thinking, stretching like a hungry pupper towards the proverbial bone right in front of him. His body wanted to slurp on that big dirty thing, even though they were supposed to be getting nice and clean.

"Feisty girl as usual, heh, I like that about you, Dicku!" Mineta grinned. The moment that the two met for the first time was the moment that their relationship began. A bitch in continued heat like Dicku couldn't possibly handle somebody like him. Which was why the big dog bitch was trying to suck him off even in these showers. "But let's get you clean before we have a bit of fun, alright? We can save the good stuff for when we get home tonight."

As Mineta said this, he pulled himself back a little and started shoving his cock in between those tits instead of letting the pupper get a chance to suck him off. All while grabbing one of the bottles of soap that were hanging around the showers, pouring that solution right across his shaft and smothering his pupper's tits in it too. All while thrusting back and forth to make sure that it was being rubbed in.

Dicku trembled and gasped and came repeatedly as his cock was being rubbed up against by another mighty rod. He was rearing his head back and howling like this was the greatest thing that he had ever experienced. All while trembling and making a complete mess of himself with all the sticky seed pouring onto his face. At least it was mixing together with the soap and making him get a little clean, even if it was only because his eyes were closed that he wasn't getting even dirtier.

Mineta continued fucking his tits and using him like he owned him, right up until he got close enough to cum. Then he let out a laugh and climbed off him, dusting his hands off and idly kicking those tits with an affectionate smile on his face. "You're a great fuck as always, Dicku. But that should keep you nice and clean for now."

To call Dicku clean would be entirely wrong, because he was completely smothered in soap and in cum that would stick to him for a while. But hey, his own pheromones had been suppressed and it was impossible for him to really smell anything except the grapes of the boy that had been on top of him. Even just the scent of his precum was sticking to the inner side of his brain, refusing to get out in any sense of the word...

"Oh, before we head out. Show me that ass." Mineta said, and Dicku's body just obeyed the sound of his voice without the words properly registering inside his dog brain. He just rolled over and stuffed that fat ass straight into the air, exposing that terribly trembling donut of a hole that was begging for something to slurp on.

Mineta was happy to give that hole exactly what it was craving, plucking a couple of grapes off his head while making sure the ends stuck together, and then stuffed the long chain of bead-like grapes straight into that hungry hole. He didn't even really have to push it, because Dicku's ass immediately started to suck it all in...

Dicku couldn't really even process anything at this point. Cumming because of his ravenous ass swallowing so many oversized grapes that acted like anal beads for a pup like him? It was completely natural. Cumming his brains out while laying on the tiled floor of the showers, all while that ass was being filled to the brim with more grapes than any human should handle. But it was okay, because he was just a pupper.

Mineta's pupper. And the boy made sure of it, when he snapped Dicku's usual collar onto him and let the pup recover from the rest of his orgasms all on his own...

---

Dicku, who couldn't even really think of himself as Izuku after being manhandled and put in his place by his dear owner, thought that things were going to get a bit better after he finally managed to recover. Unfortunately, the faint scent of grape from the nametag on his collar made sure that he wouldn't be able to. In fact, it just made his daily routine even worse.

Once it was time to try and capture villains for the sake of training his skills as a Hero, his mind just completely drained through the tip of his cock the second he saw a feminine villain. He didn't even think about anything before he pounced on her and slammed his cock as deep inside of her as possible.

The villain's partner wasn't much help either, because when Dicku had stuffed his cock so deep inside his partner that the knot had caused her to look like she was pregnant, the oversized dog-like Hero just stuffed him straight into the gap between his tits, letting him suffocate until he couldn't do anything except cum as well. It was just how Dicku fought, at least when he was overdosing on his own arousal.

None of his fellow Heroes even bothered to look towards him like there was something wrong with his way of fighting, besides Bakugou who gave him shit as usual by giving those balls a bit of tough love and forcing him to cum so hard that the villain went flying from the pressure of his intense orgasm. No, this was just completely normal.

Which was why none of them bothered to stop him when he pinned down his female allies as well. It didn't matter if it was one of his fellow students that were quickly being absolutely and horrendously bloated by the sheer quantity of seed. It didn't matter if it was a pro-hero that would likely have to retire from the sheer intensity of being a mother to so many pups. He just fucked as much as his body told him to. Because that was what Dicku did.

But Dicku didn't even think about who he was fucking. Every single time that he fucked somebody, his mind was entirely and solely focused on the grape boy that had driven him mad with arousal. The grape boy who had given him the faintest taste of his grape-scented cock. The grape boy with that massive schlong that he just wanted to suck and slurp and deepthroat until he passed out and was filled with so much cum that he'd burst!

It was why he was so intense whenever he tried to fuck somebody. It was that craving that drove him to fuck like a wild animal. It was that craving that drove him to do anything while his mind was in a haze.

And it was that craving that drove him to return to Mineta's house the moment school was over...

"As eager as ever, huh, Dicku..?"

Mineta gasped as he looked down at the total slut that was currently deep-throating his cock. Honestly, he had expected that bitch to end up waiting at home for him. He even expected the floor to be smothered in cum by the time that he came home. Because that was what Dicku did. He made a complete mess out of everything, no matter where he was.

Dicku didn't really listen, he just slurped away at the shaft in front of him. All of his brain cells were completely and utterly devoted to Mineta. Nothing else in the world mattered to him. It was just the feeling of slurping and sucking and throating that mattered to him...

In fact, he was still cumming. But the only thing that was stopping him from making a bigger mess of the floor was the chain of grapes that had been stuffed down his cock. Blocking him from cumming and making a mess. At least until he had been a good pupper and cleaned his owner's cock as much as he could.

Even though he wasn't done, Dicku pulled his head back and let the drool pour right down onto his massive rows of tits, panting and squirming as they were being absolutely slathered thanks to the sheer amount of drool. As well as the trails of cum that were drooling out after the last burst of cum that he swallowed whole.

"That's a good pup..." Mineta said, before casually slapping his cock right up against the boy's face and tits. Not to punish him, but to reward him. Because that's what he deserved.

Dicku tried to cum as he was being slapped by his owner, but all that happened was his hips thrusting forward impotently, still unable to do anything thanks to his cock being so plugged up. He wanted to cum. He really wanted to cum. It was clear from the trembling grape-colored hearts that his irises had turned into.

Mineta just laughed at the sight before tugging on a bit of string that he had attached to the grapes that were sticking out of both the pup's ass and his cock, sending them all flying out of their respective holes in a matter of seconds.

At that moment, Dicku's mind was completely and utterly broken. The sheer intensity of all those grapes rushing out of his holes caused him to let out such a powerful climactic and orgasmic scream that everything inside his mind shattered, with the remainders of his mind being fired out as cum that splattered all over. All while he slowly fell onto his back from the sheer intensity of that orgasm.

There was no longer an Izuku. There was no longer a boy that used One for All. There was just Dicku, who was Mineta's horny multi-tittied and fat-cocked pupper who couldn't keep himself from fucking any hole he saw. All thanks to his horny Quirk, Red Rocket.

And all it took to reinvigorate him was that grape-flavored cock hovering in front of his face, as he quickly started to blow it once more. Content with his life as a complete dog slut.
