Original Description:
 
“Oh my…” Marble Pie gasped shyly as soon as she stepped out of the portal. She had happened to come just in the middle of the city, surrounded by tall buildings that were barely as tall as she was and many buildings didn’t even come to her belly. She looked down and saw many tiny humans looking at her, and many of their tiny vehicles.
 
“H-hey there… D-don’t be scared… little ones…” She said with a quiet and cute voice, though it too boomed between buildings, and made windows rattle. “Oh gosh… You are all so tiny and cute…” She smiled shyly, bringing her head down to look at them more closely.
 
To her amazement, the tiny humans didn’t seem to be afraid of her, on the contrary, many hurried towards her building size hooves and Marble Pie stopped on her track as she didn’t want to step on someone.
 
“Uh… What are you doing…?” She asked but giggled when the tinies reached her hooves and some hugged them, while others started massage them. “Aww…” She chuckled. “Oh, you want to do that.” She said and couldn’t help but blush at the feeling and the sight of some many tinies coming to her. “Y-you really don’t have to…” She said shyly, feeling so embarrassed by her blushing. “B-but if you want to… you can…” She said even more quietly, feeling more and more embarrassed.
 
She let out a little gasp how good it felt to have her hooves massaged by so many tiny humans. “Uh… That is the spot…” She said and looking down she smiled so sweetly at the tiny humans. She suddenly raised one of her hooves above the tiny crowds. ““W-what if I do this… I-is it okay…?” She said, unsure how the tinies were going to react and started to lower her hoof towards the crowds, giving them plenty of time to get out of the way. “R-ran if you don’t want to be under my hoof…” She said, letting out a playful giggle and her eyes widened a bit when she saw only a few of them run away. “O-oh, that many of you want this…?” She asked, and soon she gently settled her hoof down, feeling their tiny forms under her soft, and furry underhoof.
 
“N-now you can rub the underside of my hoof too…” She smiled shyly and soon giggled as she felt the pleasuring massage. “I… I can understand why so many ponies want to come here…” She giggled, standing there and looking around what else she could do.
