Finn puttered his lips. “I know I was ready for action before, but I can’t even stand right now,” he informed. “We should probably work off these guts so we can actually do stuff. Also, you can’t see it right now, but my ramrod is so hard, it hurts.”
“Hmm, I suppose that’s reasonable,” PB conceded. “We ought to look presentable for BDSM Wizard, and I’m not sure Marceline can even fit us inside her as we are.”
“Well, as usual, you guys are totally helpless without me to save your tiny asses,” Marceline said as she stretched and cracked her knuckles. “Now, let’s see what we’re working with.” She first grabbed PB, minding the added weight as she could no longer wrap her fingers around the tiny girl’s body. Then, she lifted the pink princess in the air and turned her around. “Well, your butt looks the same,” she said before extending her tongue to lick from her ex’s slit, over her taint, and through her crack. “Feels the same, too.”
PB shivered. “O-o-oh, that was good. D-do it again.”
“Wait, I’ve got a better idea,” Marceline said as she extended her pinky finger and poked into the pink princess’ pucker. PB moaned as her limbs feebly flailed. “Tell me if it gets too much,” Marceline instructed as she slowly increased the pressure, feeling the bubble bum start to give, but only to a point. “Hmm, seems I can’t actually go in.”
“Th-that’s b-because you…” PB panted. “Okay, I think I know what you’re trying to do, but you need to start small and work your way up. Didn’t you tell me that once?”
“Good point,” Marceline agreed and gently set PB back on the table on her stomach. “Hehe, you’re just so helpless like this. It’s like you really are my living dolls.”
“C-can we please save the teasing for after we’ve orgasmed?” PB requested with a whine. “I was trying to ignore it before, but now that we’ve started, the bizonkers is setting in, and I need to cum.”
“Alright, you little stress balls, just sit back and let me do my thing,” Marceline instructed as she reached for Finn. One hand gripped his back while the other supported under his stomach. Lifting the expanded mass, she smiled as she inspected his cock. “Yeah, that looks pretty hard, alright. Then again, that’s kind of the norm right now,” she chuckled. Then, pulling Finn’s legs back, Marceline pushed his groin out as far as his body could take. “Okay, I think this is a good position.”
“Man, it feels weird when you push on my tumtum like that,” Finn groaned. “J-just what are you doing, anyway?”
Grinning, Marceline replied, “I’m gonna play doctor and make my dollies fuck.” With that said, she carefully lowered Finn atop the pink blob of a princess. She moved her face close so she had a clear view of the procedure, moving with the careful deliberation of a model-ship builder. Then, when everything seemed to line up, Marceline put the dick in the butt.
“Ngh!” PG grunted. “Why didn’t you put him in my pussy?”
“Sorry,” Finn apologized, even as he started rotating his hips.
“No, that was my bad. I was totally aiming for your pussy, though,” Marceline assured. “Want me to try again?”
PB sighed. “No, this is fine. There’s enough milk for lubricant, and I’ve taken things dry before.” She grunted as her tiny feet pushed around her gut and against the table, only getting so far before she slipped and wobbled atop her self-made waterbed. “However, you’re gonna have to move for us.”
“Hehe, that’s the idea,” Marceline confirmed. Now that Finn’s cock was safely inserted, she let his stomach drop onto PB’s back, making both people grunt. She then scooped under the pink blob and lifted the conjoined pair to eye level. “This is gonna be fun.”
Finn grunted again when Marceline pushed him into PB’s ass, causing the soft mass to compress around his hips. “Whoa, th-that’s somehow even better than l-last time.”
“Nnngh! S-so deep,” PB whimpered as the hard and burning tool stretched her rectum. “Y-you didn’t go th-that deep b-before.” Her ass spread out as Finn sank all the way to the base, only to somehow go further. It was as though the bone-like candy cartilage in her rear decided to become extra flexible to be less of a hindrance as it squished against the boy. His ramrod touched places she’d only ever reached with toys, burning and pulsing in her anal cavity. And to top it off, Finn’s hip rotations churned her insides and drove her to ever-increasing heights of carnal bliss.
Finn’s hands were useless. He couldn’t reach anything past his stomach. So, with Marceline holding his back, he focused all his might on his hips. When the vampire pulled him out, he continued rotating his hips to churn his member in his first crush’s sphincter. PB’s anus was tight and hot as it constricted his member. The milk was already used up, but her moans sounded more pleasured than pained, so he figured it was alright. Then, Marceline pushed them back together, and he was graced with beautiful friction as her anal opening slid over and swallowed his schlong. His hips never stopped as he savored all the little movements that built up the glorious friction around his cock.
“Damn, you two look like you’re having fun,” Marceline commented as she watched the bloated blobs jiggle as they moaned. “Man, I love how your fat bods are so squishy,” she said as their gelatinous forms squished around her fingers and each other as she moved them. “And you look so hot as I fuck you, especially you, princess. Ever thought you’d get your ass plowed by the cutest lard in Ooo?” When Marceline next pushed them together, she aided Finn in rubbing their pelvises together while keeping the hero’s sword entirely enveloped by the princess’ prison pocket. Where possible, Marceline also brushed her fingers against the candy girl’s sweet melons. Of course, they were little more than grapes to her, but PB’s reactions were so erotic.
“This is—Augh!—so gooood,” PB moaned as she lay limply in Marceline’s hand, utterly helpless and reliant on the vampire to achieve orgasm. “S-so deep. Sooo b-big. I-I need… Nnngh, faster!”
“Yeah, Mar-Mar. Let’s cream this pie!” Finn cheered.
“You got it, pets,” Marceline agreed as she picked up the pace. It was a little awkward to build up a fast pace while keeping her pets connected. Hearing the fleshy slaps of their bodily impacts forced her to cross her legs as she felt her panties grow damp. “You two are just too precious. Mmh, there’s so much I want to do with you. I can hardly stand it.”
PB considered reminding Marceline of her obligation to help them track BDSM Wizard, but reasoned that doing so might compromise her impending and desperately needed orgasm. So, she bit back her comment as Finn stretched her ass and said, “Fuck me hard!”
“Alright, here it comes!” Marceline declared as she kicked her doll-smashing into overdrive. Smacks grew louder as the impacts sent ripples over their swollen stomachs. The pair’s tongues fell from their mouths as they moaned. It sometimes sounded like they wanted to say things, but all that came out were unintelligible burbles of mindless lust. Marceline squirmed in her seat, going faster and faster, and wishing she’d had the foresight to insert a toy before starting. She bit her bottom lip as her playthings’ pitches rose. They were close. She just needed to give them one final push. So, spur of the moment, the vampire brought the pair to her chest and slammed them against her bobas.
That’s when the pair’s fat bodies tensed as they climaxed. Finn’s cock erupted as what felt like a gallon of hot spunk poured into PB’s bowels. Marceline watched the whole thing, enraptured as she studied their bodies’ subtle movements, noting every little twitch and spasm as pleasure shot through their systems. More interestingly, she watched as their beanbag bellies started rapidly shrinking. Was Finn cumming all that excess mass into PB? No, because her stomach also emptied. Were they literally burning calories just by cumming? Whatever the case, when the pair’s climaxes finally passed, they were still fat. However, they looked more like they’d just had a regular big meal, as opposed to being cartoonishly swollen.
Finn now lay atop PB. He rested his face against the nape of her neck while his spent dick remained wedged between her cheeks. Both panted heavily after they’d just endured… whatever the hell that was. Finally, after a brief silence where only raspy and ragged breaths were heard, Marceline broke the silence and voiced what was on everyone’s mind.
“I’m not sure what just happened, but we should do that again!”
