Fetishes: Giantess, Large Insertion
A green haired girl slowly inched her way into the Planeptune Basilicom under the cover of night. Eventually crawling in through an open window, the underling managed to gain access into a room with a minifridge. Perfect. Checking her corners outside the room, Linda confirmed there was no one nearby. It took only a moment for the infantry girl to get to work. She quickly put on a pair of disposable gloves before reaching into her jacket to grab two cups of labelled custard pudding, one reading "Nep" and the other "Nowa".
Magic hadn't told the girl why exactly she wanted these two cups of pudding switched, but what she did emphasize was how important it was to make as little contact with the replacement pudding. Or else. Shrugging it off, she acknowledged that orders were orders. The payoff was sweet either way, as she'd get to keep the stolen pudding. Maybe she could give some to Magic, and then they'd sit together while eating it, and then some pudding would stick to her blushing, near gray skin, and Magic would slowly lean over under the guise of wanting to lick the pudding but in actuality she goes in for a kiss and-
Linda, now profusely blushing, shook her head a bit. What was she doing? Oh, replacing pudding. Ever so swiftly, she swapped the pudding. Suddenly hearing footsteps down the hall, the underling made a dash for the window and darted away from chaos about to unfold.
"Aaaaalrighty girls, time for puddiiiiing!" Neptune sang out as she opened up her door, Plutia and Noire following behind her. "Look at me being so generous and offering you two girls some of my delectable, tasty pudding!" Neptune laughed to herself. Noire grumbled, pouted, and looked in another direction. Tsun tsun.
In contrast though, Plutia happily followed along on their way to the pudding, her bear still clutched tightly in her hand. Before long, and by the time a certain infantry had departed, they all gathered around the mini fridge where the Planeptune treasures lied in wait, the younger girl jumping in place as Neptune retrieved both her own and the tsundere's. The young sadist meanwhile dove right into the fridge to retrieve her own designated pudding, not wanting to give anyone else a chance to steal it.
With no delay at all, Neptune become eating her pudding with speed on par with a vacuum cleaner. Neptune, now content after eating her pudding, rested on her bed. Noire on the other hand ate hers at a normal pace. "Puddiiiiing..." Neptune joyfully mumbled out. "Nothing could possibly go wrong on a day like this..." Oh how wrong Neptune was.
Plutia barely even realized what was happening, too engrossed in inhaling her pudding with only slightly less power than Neptune. As they began eating though, the effects began almost immediately, the lilac-haired CPU beginning to lose some height as Noire quietly ate her own, finishing only as the effects started to become apparent. Their bodies were starting to shrink, and with increasing speed as well. The Ultra Dimension CPU finished her own pudding without any issues, turning around to find an... interesting sight on the bed.
"NEPU!?" Neptune panicked as she and Noire found themselves as small as a small plushie on the bed. Meanwhile, Plutia didn't seem to shrink at all. Noire was slightly panicked but more curious as to what had happened, while Neptune ran around like an idiot shouting things about "Government pudding" and "nanopuddings, son." The two stopped in their feet though, as soon a familiar shadow would overshadow them.
While the two girls began to panic and wonder what had happened, a wicked grin ran across Plutia's face, as she neared the bed. The plush-sized CPUs were completely overshadowed, as the girl climbed onto the bed, and started to reach for the girls with a giggle under her breath. This can't be good.
Both small girls screamed and ran in the opposite direction. "PLUTIE WHAT ARE YOU DOIIIIIING!?" Neptune yelled as she darted away from Plutia. "NOT LIKE THIS!" Noire shouted as she split away from Neptune.
The wicked grin only became more sinister as the two CPUs dashed away, as light suddenly flashed around Plutia. In an instant, much larger, slender hands were in their way, before scooping them up in each one. When they were brought up to eye level, their worst fears were confirmed; Iris Heart was now holding them like literal toys.
The two toys- pardon me, small CPUs squirmed in Iris Heart's grasp with desperation. "Plutia, what are you planning on even doing!?" Noire shouted. "I did nothing wrong, take her!" Neptune accused as she pointed towards Noire. Normally, Noire would have scowled at Neptune for such a comment but she was too preoccupied with the looming sadistic threat to worry about Neptune.
The dominatrix giggled as the CPUs struggled and shouted, her thumbs slipping beneath their tops and lightly rubbing against the sensitive plains beneath. Well, their breasts were still likely larger than Blanc's but that wasn't the important part at the moment. "All I wanted to do was play with you for a bit, but you two just had to start overreacting... Now I have to 'extend' our sessions~". Groaning lightly as the thumb rubbed right against their breasts, the two girls continued squirmed. "C-Cut it out already!" Noire stammered out. "Sadieeee!" Neptune whimpered.
Despite their efforts, the girls were unable to do anything to free themselves. The thumb that was playing with Neptune suddenly shot down, and threw off the CPU's panties, exposing her tiny nethers as she was lowered on to something long and thick. One cursory glance was all it took to realize what it was; yet another thick strap-on, smaller compared to Iris' usual tools but utterly gargantuan compared to the smaller Nep.
Neptune turned a little pale and her eyes widened a bit. "Woahwoahwoah woaaaah there Sadie! C-Can't we talk this out? How about if you forget this little incident or take Noire instead, I'll give you all my pudding and I'll even do your work for you so you can nap all day?" Neptune offered to work and give pudding, an obvious sign of desperation from Neptune.
Iris hummed thoughtfully, as she applied pressure on Neptune's rear entrance. "A tempting offer, from someone who's run out of options. But no, I think I'll take my toys this time~" Suddenly, the head of the strap-on slid in, forcing a massive bulge in the mini Nep's stomach. This was swiftly followed by the other several inches of false cock, each inch seeming like triple the length on her way to the base.
Neptune started with a grunt as the head pushed in, and her grunt turned into a long, drawn-out moan as the shaft pushed in. Fortunately for Neptune this isn't real life and is instead Fanfiction, thus granting stretchy stomachs. Hooray! Speaking of which, as the length neared its end, the resulting bulge stretched both her stomach and her hole.
Fourth wall breaking aside, Iris still hilted the shaft inside Neptune. She gave her a few moments to adjust to the size, before she started dragging the miniature CPU up and down along the length. She started with a brisk pace, and resumed rubbing her thumb against Neptune's sensitive breasts.
It took little to no time at all for Neptune to break and submit to the giant dominatrix railing her. While being slid up and down the shaft Neptune yelled out in pleasure, while when she felt the bump from Iris Heart's hips connecting with hers, she had a grunt as a pause to the moans.
As the fucking went on, Iris began to pull back, and thrust into the CPU as she was brought down onto her strap-on. She gradually picked up in speed, racing to make Neptune reach her climax. She glanced to Noire, who was still in the normal-sized-giant's free hand, and licked her lips. "You're up next you know~ Any special requests before I use you like Neptune here?"
Noire went more pale than before as she became further panicked. She struggled fruitlessly against the girl's grasp, doing little more than bringing a bigger smirk to Iris Heart's lips. Meanwhile, Neptune groaned out as she didn't struggle or squirm anymore, her mind and thoughts currently blurred due to the intense waves of pleasure repeatedly slamming into her body.
As Noire failed to get free, Iris made her last great push on Neptune. She dragged the CPU up and down along the shaft rapidly, fucking her senseless even faster than before, roughly fucking her brutally as she drove her towards the edge.
Neptune let out a long cry of pleasure as the shaft sheathed itself in her, creating a sickening bulge. With the final shove creating a pleasureful shock big enough to send Neptune over the edge, the CPU's eyes rolled back and her tongue lolled out without restraint.
Iris giggled as Neptune came hard on the massive strap-on, giving the girl's breasts one more rub before she pulled her off. Letting out a content sigh, Iris laid back onto the bed, still holding the two CPUs, as she morphed back into her normal state. Hopefully for Noire, the effects of whatever shrank them down would wear off before the girl decided to transform again.
