Joel brings you to Diana the Dragonite Traveling the Multiverse chapter 18 by dellobenedetto

"Well, I wouldn't mind meeting Diana."

"Okay!" Joel looked elated, and took your hand to guide you across the table, weaving in between the multitude of snacks the large gals had laid out with ease. "You're going to love her, I just know it! She's really gentle and friendly, not to mention very soft... Th-though I suppose all the girls here are soft in some amount, heheh."
You chuckled in agreement, and soon the two of you reached another edge of the table, one that gave you a good view of Diana the Dragonite. She had on a white turtleneck sweater and a green skirt, somewhat akin to the Aroma Ladies in the Sinnoh games... only with the addition of a wide-brimmed white sunhat with a green bow, and a notable midriff where the form-fitting outfit failed to cover her plus-size figure. Her card game with Lauren the Lapras and Amanda the Arcanine seems to have ended, and Ursa the Ursaluna had joined them for a conversation. "Uh, how're we going to get her attention? She's kinda preoccupied."
"_{Don't worry, I know the perfect way to get her attention.} HEY, DIANA! OVER HERE!"

"Hm?" Diana paused, her antennae twitching beneath her hat as she held up a claw, letting her friends know she'd be right back as she stood up and walked the comparatively-short distance to the snack table, gazing down at her Joltik boyfriend. "What do you need, Joel, are you ready to—...Oh my gosh, is this the human Sammy was talking about?! Aw, he looks so cute!"
"Yep, this is [Y/N]," Joel answered, given you were rather flustered by the big 'mons still finding you adorable. "[Y/N], this is Diana, my, er... m-my friend." By the end of his introductions, the flusteredness had gone from your face to his. Still too nervous to confess his love for her, you noted in your head.
"Eehee, you don't have to act so embarrassed about that after all this time," she noted, extending a claw down that you managed to shake the very tip of. "We've been hanging out together since forever, us and Gina."
"_{W-we have, but it's still a little embarassing...}"

You chuckled at that, your eyes gliding up Diana's body and trying to focus on her face despite the massive breasts in your way. "Uh, so, I've heard from Sammy and Pauline that you're a bit of a dancer?"
"Yep! Oh, but uh, this isn't what I usually wear for dancing," she noted, as she pulled an enormous smartphone from a pocket in her skirt, flipping through photos. "Not to say I wouldn't object to dancing in this, but it's not quite fitting for my dance style. Though I suppose I won't mind if it's comfy and easy to wear... Ah, here we go! See, this is what I normally put on when I'm dancing."
You stared up at the phone as she lowered it down—rather than her current Aroma Lady look, this one seemed more akin to the Dancers as they appeared in the Galar games—her turtleneck swapped out for a yellow cropped hoodie, and some tight red-and-black patterned pants replacing her skirt with a wide gap between the two garments. You could recognize a few 'mons from this party in the background watching her shake her thing, as well as another Dragonite cheering her on—judging by the shirt and, er, lack of pants, that must be her brother Draco that Joel mentioned. Speaking of, on close inspection you could see the Joltik's head peeking out of the dangerously-low waistband of Diana's pants. What a lucky guy... "Uh, w-wow, you look... really good in this."
"Thanks! The hoodie's the newest part of the look, Gina picked it out for me about a month ago. Really brings out my scales, doesn't it?"
"Y-yeah, it does..."
"Say, maybe I'll get to do some dancing tonight! It's rare for me to have humans in my audience, so you'll be a fun little change of pace. Ooh, a dance-off with Sammy to see if I can take you home, that sounds sweet!"
You recalled what that Snorlax and her girlfriend had said about Diana's dance prowess earlier, what with her being the most likely winner of a dance-off... Hopefully it's not as much of a competitive gap. "Y-yeah, it does."

"I'll ask her about it later, then! The night's still young after all. Anyway, Joel, you want a reward for how quickly you found the human? Maybe you'd like to spend some more time down beneath my booty~?"
She turned around, hoisting her tail high up to let you see the vast sheet of white fabric covering her rear. Some good-natured giggles resounded from the girls still seated at the card table as Joel's face turned red again. "_{Aheheh, y-you know how much I love that ass of yours, Di...} B-but, I-I think it's only fair that [Y/N] gets to choose."
"Ah, fair enough," she noted, casually bringing her tail down and turning around again, staring down at you with bright eyes. "What would you like to do then, little guy? I'm open to a lot of things."

It didn't take long for you to make a choice on where you and Joel should go...
