Pinkie furrowed her brow at Rarity’s words for a moment, as if her mind was processing something. “Family? You mean, like… parents? You mean like… a mom!?” She gasped, her eyes widening, the massive mare’s entire demeanor becoming overcome with excitement! “Ooooh! I’ve always wanted to be a mom! Get over here, sweetie!” You let out a startled yelp as the massive woman dashed towards you, her hoofsteps shaking the ground beneath you! Before you could react, she had grabbed you with incredible strength, hugging you against her body!
Even among the ponies, Pinkie was absolutely massive plump! Which left you completely smothered in pillowy, doughy, fluffy fat, your body tensing up as she squished your head inbetween her huge, comfy breasts, your crotch being pressed up against her massive, round, gurgly tummy. She cooed and practically purred as she swayed back and forth with your smaller body in her arms, as she planted big smooches all over your face, painting your cheeks with her pink lipstick. “Aheh… careful not to smother the poor boy,” Rarity chuckled, a bit taken aback.
But Pinkie Pie was overwhelmed with joy at the thought of being a mother! “Oooh! My very own little boy! I’m gonna snuggle you and kiss you and name you Muffinberry!”
Your face was completely beet-red at being shoved up against the massive woman’s body, but you eventually manage to speak up in a quiet, shy little voice. “Uuuh… m-my name is Thomas…”
She paused, remembering. “Oh! Yeah…” She frowned for a second, before another thing brought a smile to her face! “Ooooh! How about both? Thomas Muffinberry! I love that name! That’s gonna be your name from now on, cutie pie!” As if excited by that, she hugged you even closer, squeezing you against her, even as you wriggle about all flustered at having your naked bodies pressed together.
“I don’t think ya can just go namin’ the kid, Pinkie,” Applejack noted.
Pinkie turned to her, keeping your head deep between her breasts as she pouted. “Of course I can! I’m his mommy now! I’m supposed to decide on his name, right?”
Rainbow Dash finally interjected, her wings easily lifting her chubby body off the ground as she flew over! “Now, hold your horses! I think we should ask him first before we go jumping into decisions like this,” she insisted. She reached down and pulled your face out from Pinkie’s cleavage, turning you around in the woman’s grip! “Listen, kid, tell us. Would you be fine with Pinkie here being your, ahem, ‘mommy’?”
Pinkie gave you puppy dog eyes. “Please please please! We’ll have SO MUCH FUN!”
All of their eyes were on you, which only left your heart dropping, as all these funny feelings had left your cheeks as red as tomatoes, your hard-on in clear view. You couldn’t even muster any words! “Uuuuhh… uuummmm…”
Applejack rubbed her chin. “I think that fall’s left his brains more scrambled than a plate o’ eggs.”
Luckily, before you could get too flustered, you suddenly poofed out of Pinkie’s grip, as if you were magically teleported somehow to Twilight Sparkle’s side! She laid a hand on your shoulder as she frowned at Pinkie. “I’m sorry, Pinkie, but I can’t just let you take this specimen home. It could still be harboring all sorts of extraterrestrial pathogens… and besides, there’s all sorts of research that must be done on it! This creature is a newly discovered sapient species! Plus… I think we may need to treat it for brain damage or something,” Twilight insisted. “I’m afraid, for now, the specimen must be property of the state until we fully understand it. After that, we can let you adopt it yourself.”
Pinkie crossed her arms and pouted, looking just about ready to tear up! “Buh… but… it’s not a specimen! It’s my precious little son! I’ve wanted to be a mommy since, like, forever! Well… a mommy for someone other than Gummy, I mean!” She held her hands together. “Pleeeeaaase let me have him!”
Twilight sighed. “I’m sorry, Pinkie. But you’re just going to have to be a little patient. You’ll still be able to adopt him eventually, I think,” she reasserted. Pinkie’s posture became slumped, and even the tuft of hair on her head became cartoonishly droopy, but she didn’t argue anymore, knowing that Twilight could just teleport her away if she so chose. With that, Twilight gestured to the crowd. “Alright, everypony! Return to your normal business! The situation is under control!” Seemingly revering her, the crowd quickly dispersed, and Twilight took you by the hand and led you away. She was hardly skinny herself, however, and you had to struggle not to glance at the humongous, wide rump wobbling around just beside you as you walked.
Eventually, she made it to a huge, imposing, crystal tower, and had you take a seat on a bench outside. “Wait right here, little guy. I have to go find my assistant. Celestia needs to hear about this!” She disappeared into the castle, leaving you twidling your thumbs and gazing at the strange world you’ve ended up in. There were some moderately skinny ponies, but most, the mares especially, were at least on the chubby side, even the ones who seemed to be athletes. You even noticed some of the winged ones fluttering about in the air! Though the pudgier ones seemed to have trouble flying very fast…
Suddenly, as you’re looking up at the spectacle, you’re veiled in shadow. You turn your head… only to see a MASSIVE pink booty looming over you, taking over your entire field of vision, the deep, dark crack inches from your face. “Shhhh, stay quiet for mommy, cutie pie,” you heard Pinkie Pie’s voice say… before that booty came crashing down! You suddenly found your naked body thrust halfway into that deep canyon between those mammoth cheeks, your nose full of the musk as you were soaked in the sweat covering the energetic mares rump. You struggled all you could, but those doughy cheeks restrained you with their weight and muffled your voice! Meanwhile, Pinkie tried to act natural, yawning and crossing her legs as she hid you beneath her. “Yaaawwn… nothing to see here… no siree, nothing suspicious is occuring…”
Once she felt comfortable nobody was looking, she finally trotted away, trying to act natural and hoping no one saw your kicking legs dangling from her sweaty asscrack. Eventually, she ducked into a nearby alleyway, finally pulling you free from that sweltering canyon, leaving you gasping for air as she set her hands on your shoulders. “Sorry about my friend there, Muffinberry! She can be such a total meanie sometimes!” She said, excited as she was confident she’d snatched you away from Twilight unnoticed. “But now that you have your new mommy, everything’s gonna be all okay! I’m gonna take gooood care of you!”
