[Universal Fetish: Latina Ass (1B+1D, 2C); Desire to Fill Asshole: Latina Women (1A+1C, 2C)]

Charles strokes his chin as he processes what you told him, "Hmm... interesting. Whenever race comes up you usually go for Asian chicks. I guess that makes you the black sheep of the multiverse. Then again we are talking about infinite possibilities here, so I suppose I was bound to find the Latina-loving version of you eventually."

You raise a brow, baffled by his rambling, "...Huh?"

He blinks, as if he's just remembered you are there with him, and waves it off, "Nevermind. Anyway, if I'm understanding you correctly the first thing you want is a world where everyone has a fetish for Latina women's asses. Care to elaborate a bit on that?"

You nod and say, "Sure. Basically I want to make it so that everyone in the world loves Latina ass as much if not more than me. I want the fetish to be so common that no one bats an eye when it's brought up in conversation, and strong enough that even the straightest woman or gayest man would cream their pants if a Latina started twerking their naked ass against them."

Really, you're not convinced that Charles was telling you the truth. But you figured that you might as well take the chance to go all-out with your perverted fantasy. You expect Charles to drop the charade, or tell you that was impossible, or give some other excuse as to why he couldn't do it.

Instead, to your surprise, he nods and says, "Alright, makes sense you'd choose a 2C modifier for that. Of course there's going to be a limit as to how much people obsess over Latina ass, if only to keep society functional. But trust me, that still leaves a LOT of room for societal change. It'll be interesting to see how people end up expressing their love for booty. Now based on your other choice, I'm assuming this doesn't extend into full Free Use, and that Latina women themselves aren't as entranced by their own asses as everyone else."

"No it doesn't, and yes," you answer in order, before adding, "Though I'm imagining that Latina women in this hypothetical world still have some love for their own butts, and wouldn't ever feel it necessary to get things such as implants."

"Like them natural, do you boy?" Charles asks with a smirk, "I suppose with your interest in baboon butts you aren't much of a silicone fan."

Your cheeks go red, and Charles chuckles, "I'll take that as a yes. Anyway, for your second request you want all Latina women, 18+ of course, to have a constant desire to fill their assholes with... wait, what exactly do you want them to fill themselves with?"

Yeah it is a little complicated you think. Taking a moment to figure out how you want to phrase it, you eventually explain, "Well, I want them to have a constant desire to fill their asshole with my dick and only my dick."

Charles looks at you with his head cocked, "Huh. Like every Latina woman on the planet? That'll be interesting. Women who have never met you will want to be filled with your dick. Really it's kind of brilliant when you think about it. You care to elaborate a bit? We want to get this right for you."

"Uh, yeah. So like I said, I want all adult Latina women to constantly feel a need to fill their butt with my dick. Obviously they can't satisfy this desire directly all that often unless I'm in the vicinity, so as a trade-off I want them to be able to stuff themselves with butt-plugs that are shaped exactly like my dick. But if I am nearby, I want them to approach me and beg me to fill them up personally. If I'm so kind to indulge them, it'll be the best moment of their life, something akin to a religious experience! You could say that my dick will make them feel completely fulfilled."

Charles rolls his eyes, then says, "You're giving yourself quite the power trip, but I'll be honest, as stupid as that pun was the idea itself is incredibly creative. Entire industries will pop up just to create molds of you cock! Don't worry how it works, Doc will take care of the rationale behind it. I mean, we might have to make some illogical jumps to make it all work out, but it'll be smooth."

Charles nods a few times, appearing to think through possible iterations of how this world comes about before turning back to you, "Alright kid, let's talk modifiers. The 1A makes sense. They only want your cock and only you can stuff them up. As for the 1C, that makes sense too: without your real dick, it's a personal solo thing, and if you happen to show up, they're going to compete with one another to be the one to get your dick. There's only one of you to go around, after all. And I suppose with the 2C modifier you want all Latina women to talk about how much they want their butts to be filled by you cock all the time, right? They'll treat it as an active part of their lives. Just like they might talk about politics or their favorite show, they'll also talk about your cock. Nice, nice."

Charles seems to realize something, and starts laughing maniacally, "Oh man, and with everyone else loving Latina ass so much, it's going to almost be **** for them! They all want a piece of that booty, but all the Latina women want in there is you!"

"That's the idea," you say with a grin, "And can you make it so that even if they are willing to take it up the butt with someone else, they'll be pretending to have sex with me?"

"Yeah, yeah, we can do that," Charles says, wiping one of his eyes as he recollects himself, "Damn, that'll make anyone having anal sex with a Latina girl a cuckold to you! Physically she'll be having sex with them, but mentally it'll be all about you. It'll be interesting to see how people end up dealing with that!"

Charles reaches into his pocket and pulls out a small flip phone that looks about a decade old, "Right then, lad. I'll give the doctor a call and you'll be on your way."

Punching numbers in, he puts the phone to his ear as the dial tone starts playing. Not long after, it stops and a muffled voice you can't hear very well from your end speaks up.

"Yeah, doc, he's got it all planned out," Charles said with a small laugh and a smile, "It's almost diabolical, really. I actually think it's pretty solid, yeah. Here's what he came up with..."

You can't help but feel pretty good about the fact that you managed to impress this man.

Charles relays the information to the point, and after some silence, the muffled voice says something very briefly before hanging up on their end, causing the call to drop. Charles turns his eyes to you as he closes his phone and stands up from his seat, "That's that. Now, if you'll follow me."

Getting up from your own chair, you follow the foreign gentleman through the maze of crates, occasionally passing an emotionless guard with eyes hidden behind heavy sunglasses. Your heart racing, you're still not sure what exactly to expect. How is this going to end...?

"Here we are."

Looking around, you see that you and Charles are suddenly at the end of a very long white hallway, walls painted with streaks of black. In front of you stands a large black door with curved handles of silver, standing impressively tall.

How... and when? Why are you in this hall? You were in the warehouse just moments ago... right?

"Don't think too hard, lad," Charles says with a dismissive chuckle, "All I need you to do is imagine where you want to be when you open this door. It's that simple. Could be your shitty apartment, could be the halls of your college, could be a movie theater downtown...just think of where you want to be as you start to explore and exploit the world you've created."

Well, you've already come this far. You've listened to this insane gentleman prattle on about your casual fetishism and you've ended up in a white hallway beyond all logic... so there's no point in trying to figure this out now. You decide to throw caution to the wind and go all the way, seeing this ride through to the end.
