"You think you could bring me to Lilly?"
"Oh, sure!" Sammy clutched you to her chest as she entered the living room, focused on the Lopunny girl. "_{Though, uh, don't be too surprised if she ends up showing you around to everyone, she has a habit of doing that with tinies she finds.}"
"I-I won't mind. Especially since I'm sure everyone will know about me one way or another by the end of the party." And one already has, you thought to yourself about Grace.
"_{Alright then.} Hey, Lils!"

"Hmm?" As Lilly perked up from hearing Sammy call her name, you got a chance to look her over; while you weren't sure if it was just your dimunitive stature compared to her or not, it seemed like she had the thiccness of at least 5 regular Lopunny put together, with a lot of her fat centered around her boobs and thighs. Said breasts and thighs—well, those and the rest of her legs—were the only things covered in clothing, specifically a black top and black pantyhose mimicking her mega evolution. You could even see the faint dip her pussy caused in her fur as she shifted her weight. "What is it, Sammy?"
"Well, I have... have something I'd like to show you."
"Ooh, is this what Grace has been giggling to herself about for the past few minutes?"
"Hm, you could say that... Here."

And the moment she lifted you up, high enough that she could see you, you swore that Lilly's eyes widened like she'd gotten a toy on Christmas. "EEEEEE! Oh my gosh, a tiny! You brought a tiny to the party, that's so cool! Where'd you meet 'im?"
"Oh, just out at one of my napping spots," Sammy explained. "He was clambering up onto my body and ended up wanting to stick around when I awoke."
"Aw, how sweet!"
At this point, you felt it important to speak up. "Uh... T-the name's [Y/N], by the way."
"Nice to meet you, [Y/N]!" She took you from Sammy's grasp and brought you up for a big, elongated kiss that briefly coated your body in lipstick. "I'm Lilly, though I guess you already knew that, huh."

As you nodded, Sammy chuckled. "Well, I'll leave you two to get acquainted, then. Gonna go see what snacks everybody brought."
"Okay, you go do that! See ya, Sammy!" Once the Snorlax had left, Lilly brought you over to a cushioned chair, sitting you down on the armrest a tad roughly. "Y'know, Grace and I have a few tinies living at our home."
"Y-you do?"
"Mm-hm! More humans, about as small as you, and so easily flustered by our boobies even after, what, living with us for the past three months?" She jostled her rack to emphasize her point, though this was followed by a few moments fussing with her top to get it back into a comfortable-looking position. "^{Euf, so tight...} Oftentimes, Grace and I let them tag along around the house, and we'll bring them into the shower or bedroom if we're feeling spicy~. Joel has that privilege, too."
"Huh?" That new name caught you off-guard. "Joel?"
"Oh, did Sammy not tell you about her?" As you shook your head, she continued. "He's probably the smallest member of our friend group, a Joltik who's... what, barely twice your size? Could probably give you a ride like a Mudsdale or Rapidash if you asked. Grace let him tag along to the party by riding under her dress, and he's probably getting sat on by Diana as we speak." She let out a wistful sigh, letting her ears swing back as she turned towards where the Dragonite was seated, playing cards with Amanda and Lauren—and very prominently shaking her big booty like there was something beneath it. "Hah, what a lucky little perv... Some day, he'll work up the courage to tell her he loves her... _{Though between you and me, I think it's more likely she or one of the others will tell him the reverse first, eehee.} Oh! That's an idea, I could introduce you to them!"
"W-wait!" You were a tad panicked at being carted off to another big, beautiful Pokegirl so soon, and gestured in panic to make Lilly pause. "W-wouldn't you rather spend time with me? I-I mean, Sammy gave me to you, didn't she?"
"I suppose. But maybe... Hmm, let's see..."

What does Lilly end up doing with you?
