Rainbow Dash is fat. Rarity is muscular. They bang.

“Oh gosh, Rarity.” Rainbow Dash whimpered, her flab jiggling and shaking as she panted. “Keep going.”

“Mmff,” Rarity grunted. She dug in even deeper into Dash’s clit, her thick arms doing their best to push Dash’s tree-trunk-thick legs apart. Her well-practiced tongue ran up and down Rainbow’s pussy, twisting and lapping at her well-juiced walls until Dash cried out, her body shaking and convulsing as her orgasm rolled over her.

Dash let out a long, low groan. “Ugghh. That felt amazing.”

“Did it?” Rarity asked sweetly. She pulled away from Dash’s crotch and wiped her mouth, savoring the taste of Rainbow’s sticky sweet juices on her mouth. She slowly leaned forward over Dash’s flabby chest, loving the way her biceps curled and pressed against Rainbow’s fat as she slowly squeezed her way up the fatter mare’s front.

Rainbow Dash shivered. “Crap, Rares. You know how doing that gets me.”

“Doing what?” Rarity asked innocently. She trotted her fingers up Dash’s massive, protruding belly and gave her flabby breast a quick squeeze. Dash gasped, shuddering in pleasure again as Rarity pressed nuzzle against Dash’s, loving the way her melon-sized, iron-clad boobs squished and squeezed against Dash’s fat.

“Th-that,” Rainbow said. “Reminding me of how - ugh - how fucking fat I am.”

“But that’s what you are, darling.” Rarity fluttered her eyelashes and sat up on Dash’s chest. She ran her fingers down her own sides, making sure to flex her bulging six-pack, which stood in clear contrast to Rainbow’s own fat-filled body. “There’s absolutely nothing wrong with reminding such a fat mare that she’s nothing but a pile of lard next to an - mm - thick, well-sculpted specimen such as myself.”

“Great,” Dash muttered. “Pile of lard? Now I’m horny *and* hungry.”

Rarity laughed and gave her a peck on the snout. “Cake?”

“Always.”

A light blue aura surrounded Rarity’s horn as she levitated a slice of chocolate cake over from the table where it’d been waiting patiently for Rainbow Dash’s summons. “You know,” she said, a shiver of pleasure going up her spine as she rocked her hips back and forth, letting a fold of Dash’s fat pleasure her own marehood, “we should do this more often.”

“Only if you - mmff - bring cake,” Dash grunted between bites. Rarity moaned to herself, her right hand’s fingers playing with her labia as her left slowly caressed Rainbow Dash’s fat, jiggling tits.

“For you?” Rarity said, licking her lips hungrily at the sight of chocolate frosting smearing Dash’s mouth and double chin. Privately, she wondered if she could bring enough cake to make it a triple chin. As heavily muscled as she was, it was always nice to have a contrast to buff one’s buff ego - and Dash seemed so absolutely willing to provide. “Mm. Always.”
