[Pin-Up] The BIG Nut (Futa) - April Patreon Pin-Up

***

"Hey Squirrel Girl, can you come over here for a sec?"

Doreen, better known as Squirrel Girl, slowly creaked to a stop on her swivel stool, and turned to face Peni Parker. After the last match, Peni's SP//dr mech took some hefty damage, and with their next match fast approaching, Peni asked Doreen to give her a hand with some of her repairs.

"I really appreciate you giving me a hand getting my mech all fixed up, it's not easy for me to getting to the tall bits!" Peni said. "I didn't realize you knew so much about robotic engineering, and I think we're almost ready for the next match."

"Hey, I was happy to help! Heights are kind of my thing, and it was really cool to see how the mech worked! Besides, us gals have to stick together, right?" Doreen smiled. It wasn't often that someone acknowledged her intelligence, and spending the past day with Peni had been a great change of pace.

"Well, last match when I was totally kicking the crap out of Loki, one of my spiders found this huge acorn outside. I've never seen one this big before, and I thought you'd like it!" Peni said. With a flourish, Peni pulled from behind her back an enormous acorn. The nut was as big as her fist.

"Oh wow, that's amazing! Hey, thanks a lot, this looks really good!" Doreen exclaimed. "I've never seen one this big either, I wonder what kind of tree it came from..."

Doreen took a bite out of the acorn's hull, and squealed in delight. It tasted like a typical acorn, but the sheer size forced her to crunch it down in several bites. Peni watched her finish the nut with curious expression on her face.

Doreen licked her lips. "Oooh, that was really good! Thanks for finding that for me, I...oogh..." Doreen paused, her belly rumbling. "I think I just ate a little...too...much...?" She doubled over, her arms wrapped around her belly, grimacing at the sudden strange sensation.

"Hey, are you feeling alright? It doesn't hurt, does it?" Peni asked, concern starting to edge her words.

"No, no... I'm fine! I think it just went down the wrong...pipe." A red glow began to emanate from Doreen's belly and soon spread over her body. "I should probably...talk to Mantis...sooOOOOON!"

With a cry, Doreen flung her head back and suddenly surged in size. She grew several feet taller, and her feet swelled in her shoes, the bulging material straining. Her other clothes briefly tightened around her growing frame before they were torn to shreds, and her toes burst from her stricken footwear. Her clothes in tatters, Doreen staggered backwards, her body growing unevenly and herself vaguely aware of how far away the ground seemed to be getting. With a final surge, the remnants of her clothes fluttered away, and she yelped as her head bonked against the cave ceiling. She slowly opened her eyes, and glanced down at an excited Peni, who was grinning madly.

"YES! YES! Forty feet, right on the money! I wasn't sure how much to add after diluting it, but it looks like it retained most of its effects even after being infused." Peni pulled out a notepad and began to scrawl some notes. "How are you feeling? Did it hurt at all? How many fingers am I holding up?"

Doreen, still reeling from the growth, pressed her hands to the ceiling to steady herself. "Wh-what happened to me? Where are my clothes?" She boomed. Her voice echoed around the cavern, and she felt unsteady from her new vantage point.

"Pym particles! I've been trying to find ways to better control the growth, and so I injected them into an acorn. The acorn grew a bit, but the grown cells became saturated with Pym, and wouldn't grow any bigger," Peni babbled excitedly. "I theorized that the excess Pym would still retain its growth ability, but I didn't know for sure without trying it on a subject! This is a great discovery!"

"You tested those particles on ME? Why?" Doreen exclaimed.

"Well, if I'm honest, I'd love to try using them myself, but I wasn't sure what kind of effect they'd have. Plus, if I got big then it'd be a real pain to use a computer to fix myself again, so I needed someone who was around my size to test it on!" Peni flipped the page on her notepad. "So, what are you feeling now? Can you move? Can you walk? Can you crush unsuspecting Gods with the fury of the mortal queen?"

"I feel...", Doreen shook her head and glared at Peni, "...angry! How could you trick me into becoming your test subject? I was having a lot of fun working with you, and now I find out it was all some big fat...setup? I can't believe that I THOUGHT we were on to a good thing, and now I'm taller than an oak and you don't have the decency to hand me a tarp!"

"Look, I'm sorry that I didn't tell you, I needed to make sure there was nothing that might skew the results! I'll get you back to normal in a sec, I just want to run a few more tests just in case." Peni closed her notebook and glanced up at Doreen, who self-consciously wrapped her arm around her bare breasts.

"Hey, I'm sorry about your clothes... I really thought the Pym particles would work on them too. I'll get the fabricator up and running, and we can get you something more comfortable- ". Peni stopped short, suddenly aware that Doreen wasn't listening. She looked up to see Doreen gently massaging her breasts, tracing her curves and squeezing her puffed nipples. As she rubbed her thighs together, Peni realized that Doreen was starting to glow again, but this time the glow seemed to emanate from her breasts and hips.

Doreen began to squirm, her breathing becoming more labored. She squeezed her eyes shut and bit her lip as her breasts began to swell, growing heavier and fuller with every passing second. Her thighs followed suit, growing thicker and melding into her widening hips. She tried to stifle a moan, but it escaped her lips as a fresh surge wracked her body. She tried to stoop, both due to her steadily increasing height and unbalanced weight of her chest, but was forced to settle on her meaty haunches as her proportions continued to diverge. Her breasts tumbled down her belly, sagging between her thighs as she tried to balance her shifting center. Her hand briefly lingered between her legs, but she braced herself against her thigh, her fingers settling into the soft flesh. She shuddered as the growth seemed to have run its course, and dragged her eyelids open to see Peni standing stock still, her mouth agape.

"Are...are you alright? You..ehm...grew a bit...more?" Peni began to blush, unable to drag her eyes from the heaving mountain of flesh across from her. ""That...that wasn't supposed to happen. The Pym particles are only supposed to last for one charge, and you're grew way more than that dose should have allowed."

Doreen wasn't listening, and was instead preoccupied with exploring her new dimensions. She gently caressed her enormous thighs, squealing in pleasure as she delved into the new tender flesh.

"Oh wow...", Doreen whispered in a daze, "That felt... so amazing! That sensation... it felt like everything was rubbing together all at once. I feel so big...so heavy...", Doreen trailed off, squeezing her engorged breasts. Peni couldn't help but stare as her teammate continued to explore her swollen figure, seemingly oblivious to Peni's presence.

"I..uh...think we should focus on getting you back to normal, right? I mean, after all, you don't want to stay that big forever-".

Doreen snapped out of her trance and eyed Peni with a devious smile. She leaned down, her breasts brushing against the floor. Peni swallowed hard and took a step back as Doreen loomed in front of her, trying not to think about how the girl's nipples were twice as large as her own face.

"You know," Doreen cooed, "You're kind of cute when you get all... flustered." She leaned in closer to Peni, her breathing heavy and shaky, heat radiating off her like a furnace.

"Maybe we could---mmMPH!" Doreen let out a thunderous moan, her body twitching as she sat back and gripped her chest. "I...I feel it building again! It.. it feels so GOOD."

Doreen's body began to glow again, the color and heat rising as the tension built in her already ample assets. With a cry, she began to swell, the flesh multiplying and flooding between her fingers. Every surge caused her body to quake, the impacts sending shockwaves along her voluptuous figure. She sank to one knee, her expanding breasts squishing to make way for her burgeoning thighs as she grew bigger, taller, and thicker. Once again, she pressed against the cavern ceiling, bracing herself against the rock as her body continued to surge. Peni stumbled backwards as Squirrel Girl grew, the girl's breasts hanging over the tiny mech pilot like the world's softest guillotine.

"Mmm... that was even better than the last one." Doreen licked her lips, dragging her fingers across her chest. "I think you're right, those whatchamacallit particles really are something, and we really ought to run a couple of tests... together."

Doreen reached out and snatched Peni from the floor, holding her tight in her fist. Peni struggled against the giantess' grip, but couldn't seem to wriggle free.

"I think we ought to try to get to know each other again... and next time you're going to be the lab squirrel."

Here's the futa version of this month's Patreon Pin-Up, suggested by Tog@bi2! It's been a while since we've had some non-Overwatch content (even though this definitely does not take place in Gibraltar), and I'm pretty happy with how this one turned out! I hope you all enjoy this captioned set, and I'll see you all soon!
