[Possession, Feminization, Boy Tits]

"Haaaaaaatooooooo!"

The loud voice calling out for her dearest friend and writer echoed through the Forbidden Archive, as the owner casually strolled down the halls decorated with bookcases. No matter how many times she came to this place, no matter how many times she stopped by, she never did figure out how to navigate the place. But then again, knowing that friend of hers, she didn't need to worry. She'd find a way to find her one way or another.

Her name was Blair. Her skin was a nice darker shade, and her body was as sexy as one might want it to be. Well, at least as sexy as she thought it could be on a regular basis. And if she ever wanted to change it, she could do it with a snap of her finger. That was the power stored within her, and it was one that she had granted a couple of times. Mostly when she wanted to take out her frustrations and just have a bit of fun with the worlds she enjoyed.

"Please don't yell."

As Blair came to a stop, the bookcases suddenly collapsed into nothing and a white-haired black-suited woman revealed herself, while brushing a hand through her hair. "Oh, that's where you were." Blair chimed, grinning as she immediately ran over to her best buddy, grabbing ahold of her and ramming her face straight into the t-shirt and fistnet combo that covered her breasts.

Hato, as Blair had called her, was almost immediately silenced as she tried to scold her friend for her continued rambunctious behavior. But once she was snuggled straight into those puppers hanging from her chest, she grew mysteriously silent before just sighing. She had no real reason to be angry, even if she had been disturbed during her writing time.

"What do you want, Blair?" Was all that she bothered asking, pulling herself out of the top of the darker-skinned visitor's cleavage. "Better not be more boy butts. I've got a lot of straight shit to write and I can't concentrate on the hetero process if you keep showing me Deku's fat fucking ass." She elaborated, her tone being distinctly relaxed around a close friend like her.

"Of course I'm bringing boy butts, what do you take me for?" Blair grinned as she kissed her pale-skinned writer friend on the forehead. "Besides, I was wondering if you could help me put some attention on those boy butts. You know, make them stand out so much that people'll want more!"

Hato slowly pulled herself away, a feat that required her to repeatedly slide her head up and down through the cleavage until her guest moaned too hard to keep a grip on her back, before clearing her throat. "You know I don't think my boy stories have that much traction. What if I want to get more eyes on my works in general?"

"Buddy, you know what you write." Blair replied, not even giving her friend the chance to argue. "Besides, you've written that Gauntlet story for me. The chance of people liking that isn't that high, but you still did it." She chimed, grinning a bit. "Big thanks, you know? But, when're you going to do the next part?"

Hato smiled a little. Yeah, it was nice to hear that from a good friend. What ultimately mattered to a writer like her was that people were satisfied. Even if she let them wait a bit longer than she really wanted to. So, better figure something out that could help out with Blair’s needs, just so she won’t be disappointed.

"Right. Okay." Hato muttered, before snapping her fingers as a cozy living room chair flew over to her, letting her take a nice seat as she looked at her guest. "You're not wrong about what I write. And we can make arrangements for the semi-final part soon, maybe even focus on a boy-centered piece. But I really, really need to work on other pieces. Otherwise I'm going to end up behind again. And then you're not getting any more content with my boys or my girls. And I know you do enjoy them."

Blair nodded and sighed a bit. "Alright, alright. Well, can you still help me get some then? Surely you know somebody that'd write boys." She asked, stretching a bit. She really just wanted to go to town on somebody cute and hunk-y. Maybe even somebody that was like her, just still shutting themselves away because they weren't sure the world would accept them.

Hato scratched her cheek a bit as she let a few options fly through her head. She definitely couldn't write for her, she already explained why that wouldn't be possible. But there was one idea...

"You know..." The Writer muttered as she let one of her bookcases pop back out of the ground after she had made it disappear, plucking a featureless book from its shelves. "I could just let you wreak havoc inside one of these books, and then let the story write itself. It'd be kind of like how you influenced Makoto in the Gauntlet story, just more directly. Not that you really need me to help you do it, but it would mean we get to spread your fun to others like before."

Blair tilted her head slightly as all of what Hato said basically went in one ear and out the other. "Simplify it a bit?" She asked, while grabbing the book and looking at it to make sure it wasn't special or anything.

"You jump in book, you fuck around with the boys you want to fuck with, and then everything'll be recorded and turned into a story. Presto, we have some smut that people can enjoy. That's how easy it'll be." Hato explained, another snap from her fingers making the book open up and reveal the empty pages. "Just climb in and we can... Actually, hold on, what boys did you want to mess with?"

"The Vanguard boys. Ren in particular." Blair answered, sticking her hand into the book and smiling a bit as what Hato had said rung true, it really did feel like she was going into another world. "Anything I need to know before I go in? You're the expert on that universe."

"Deal with Kai. Ren's obsessed with him, more so than he'd be obsessed with you." Hato explained, grinning a bit. "Actually, I remember how you got real mad at his obsession. So why not take advantage of that? Get rid of Kai, make Ren yours, all with one little push."

Blair's eyebrow twitched a bit as she got the awful reminder, but the tip did help. "Right. Better be ready for the Gauntlet story next time I stop by, otherwise you're getting the ass treatment instead of the tit treatment!" She said, warning the writer in the process, before sinking into those pages...

Hato shivered a bit as she closed the book, tossing it onto the shelf. Getting pinned under Blair's nuclear waste-producing ass was the last thing she wanted...

"He's still gone so far. And it's not fun to play against him when he's like this. Isn't there anything I can do?"

A young man sat at his desk at home, shuffling through the cards that he always used to Cardfight. A young man who pursued greater and greater heights. All on his own. He didn't want anything except a good fight. As long as it was a fair one.

But seeing his good friend turn down a darker path was what started to break him. Not that he hadn't had a great life already. But seeing him slide wasn't helping. It was why he had shut himself off to a point, only breaking out once he started fighting alongside that blue-haired boy...

Toshiki Kai was the young man's name. And his pursuit of greater challenge was outright mirrored by the way his friend had fallen to try and beat him through greater power. A feat that had turned hollow to both of them, because they kept trading games. Even now that Ren had gotten so powerful, he still lost on occasion to the friend he once had. And Kai wasn't sure how long he'd be able to keep that up, as his heart ached every time they fought...

...No. He just had to keep fighting. Until he dug away at his friend and made him return to normal.

"Aw, isn't that sweet? You're just as obsessed with Ren as he is with you. But you don't realize he wants more than that!"

Kai's eyes flew open as he tried to figure out where that voice was coming from. A woman's? He couldn't be sure, it was definitely feminine by nature, but given the way that people presented themselves when they pictured their avatars, he could be dangerously wrong...

"Down here, handsome!" The voice spoke out again, and the brown-haired young man looked at one of his cards. His prized Draconic Overlord, the Avatar that had stood beside him in every single fight...

It had been replaced with the rather lewd visage of a darker skinned woman, though not one with dragon-like features. As far as he saw, that was just a normal woman. At least, at first glance. But the fact that she had definitely been speaking meant that there was more to her than meets the eye.

"What are you..?" He asked, about to get up from his seat and get away from the talking card. His instincts told him to run. Even though he thought that he might be going a bit delusional from a lack of proper sleep thanks to the Ren issue, this was...

Just as his mind started to try and rationalize why one of his cards had been replaced with the visage of a darker-skinned beauty and started to talk, a circle started to appear around it. And that very same circle appeared below his feet, as a rush of energy suddenly started to fill him.

"Superior Ride! Blair!"

It wasn’t the card’s voice that spoke this time. No, it was his own voice, forced to say what the card wanted to say. And as he did, the ‘cards’ influence grew more powerful as he staggered backward. His skin started to turn the same shade as the one on his favorite card, while his voice grew distinctly more feminine with every breath he drew. He could even feel his body growing thicker the more he tried to struggle against his changes.

His hair turned nice and dark-purple as it grew longer, with part of it extending behind him as it tied itself into a neat little bun behind his head. His clothes were shifting into the same sort of top that covered the one on the card, only his new shirt was covered in a punk-like female version of Draconic Overlord, while the fishnet didn't seem to do much since he didn't have tits. And the stretchy pants that replaced his own certainly still fit him, even if they were a bit loose since there wasn't nearly enough junk in the trunk.

At least, that's what initially happened. As Blair's influence fused with him more and more, all that came to change. The most egregious changes being what happened up above and below, as the young man let out moan after moan as breasts started to push out from his chest. Big, thick, heavy melons that were kept nice and pinned against his chest thanks to his fishnet. Those things were nearly so thick and heavy that they were starting to leak, as if there was a bunch of milk stuck within them. Those big boytits fit his new form perfectly.

The changes down below were making sure that he fit snugly into those stretchy pants, as his ass pushed out further and further. The junk was being stuffed inside his trunk, as one of his asscheeks was now the size of his head. And even then it kept on growing, making the fabric stretch more and more until it almost started to cover less of his legs in the process. His ass grew to a point where just breathing was enough to make it twerk, something that was already bringing him quite a bit of pleasure...

But it couldn't end with just his ass. No, Blair loved what was in the front too. And that was why Kai felt an extreme pressure building in his crotch, his hips instinctively thrusting forward until..!

"Haaaaaahhhh!" He let out a scream as his cock practically erupted into an enormous shaft, as thick and as long as his brand new thick thighs. That third leg was pouring out so much seed, all supplied by the fat balls that were squeezed between his cheeks. All while he quietly relinquished control of his body to the one that had performed a Superior Ride on him...

The young man let out a powerful moan as his stretchy pants were quick to swallow the cum that poured from his thickened shaft, all while a subtle smile started to grace his lips. Blair was now in full control, and there was something that she wanted to do, now that she had spiced his body up.

It was time to go pay a visit to Ren, and teach him what he had been missing out on.

"Oho? You've finally come back, Kai? What's with that new look-"

Kai's reunion with Ren had been rather abrupt, as Blair guided the young man's body straight towards his good redheaded friend. The redhead who was still obsessed with power. But under that veneer of teasing, Ren was unable to really process what he saw, leaving him utterly vulnerable to anything that the changed youth would do to him.

"Just setting the record straight." Kai grinned as he pinned his friend, that edgy dork, up against the wall. And pressed his cock straight against his crotch, licking his lips a little. "Let's skip the cardfight and go straight to what we've always wanted. Right, Ren?" The way he just took control wasn't out of the ordinary for Kai. He had a way to show his dominant streak. It was just a little odd to see him being this openly sexual, especially given that those tits hadn't been there yesterday...

"A-Aha... W-When did you think this was what I wanted?" Ren's confidence had been all but swept away as Kai took charge. Something about his feminized form, something about that cock… Something about it all was enough to make the redheaded boy’s heart beat harder and harder. He wanted it. He needed it..

Kai didn’t bother giving him a verbal answer. A kiss on those lips was all that he needed. Especially as he lifted him up, with much more power than he ever had before, and then slammed him down on his pants-covered shaft. He didn’t even bother removing them. Why should he, when they symbolized part of his dominance?

Ren’s eyes immediately rolled into the back of his head as that tick thing slammed into him. He wasn’t even close to ready for this. How could he have been? He always wanted to play with Kai and defeat him with his own power, but this… Was this what he had wanted all this time? Had he wanted this? To pin him against a wall and… and…

Something inside the redheaded boy snapped as he started moaning up a storm, helped along by the way that his friend kept pounding his hole now that he was nestled snugly inside of it. It felt good to be fucked. It felt really good. He never wanted anything else except to have his slutty femboy hole fucked until it got so sore that it wouldn’t be good for anything except being fucked. He wanted to keep being used by Kai, he wanted to keep being rammed into like this. He wanted it, he wanted it!

Kai grinned as he saw how quickly Ren broke in the face of his power. He should’ve quit trying to beat him with his cards long ago, if this was how he turned out when he got a taste of a cock. Ah, just looking at the way the boy broke was enough to turn him on even more.

“Final… Turn..!” The big-tittied young man cried out as he pounded his friend even harder, panting like a mad dog the more he did this. It felt so fucking good. It didn’t even matter that he had been influenced by somebody else. He was enjoying the experience of completely and utterly breaking this hole in to the point where he couldn’t imagine doing anything else. He just wanted to fuck Ren as much as Ren wanted to be fucked..!

The two friends’ relationship was quickly deteriorating. Not that either of them cared. As far as they knew, they were meant to be this way. They weren’t quite lovers, more like Master and Pet. And as long as Kai was willing to completely and utterly destroy Ren’s asshole, then the Pet was more than happy to be used like this. This was his one purpose in life. To satisfy him..!

Blair, essentially layered on top of Kai in a sense, could help but grin a bit from her front row seat to the action. This was more like it. While sure, she wasn’t getting the kind of love that she really wanted from the boy she crushed on, seeing him break like this thanks to the young man he obsessed over… Mmmph, there was very little that could be called better than this.

She really had to thank Hato for this opportunity. But she also had to pin her beneath her ass at least once before the next time she’d punish her. There was no danger of gas in the future, just a bit of a reward… And maybe a bit of gas. She was a tricky gal after all.

For now, she was going to enjoy the gay show in front of her… And then see how far she could push them...
