Marceline was in the middle of practicing her next solo when she heard a knock at the door. Given that she lived in a secluded cave-house, she didn't get solicitors very often, and anyone who had the stones to knock on her door interested her. Usually it was just PB surprising her with a visit, or Ice King having one of his episodes and wandering his way in.
But instead of either of those two, Marceline opened the door to see Finn on the other side.
Marceline was shocked to see the young hero show up unannounced, rocking back and forth on his heels, looking a little shy but otherwise playing it cool. Marceline just... invited him in, letting him stroll into her living room and crash on her couch. There was a little bit of awkward small talk, but they eventually broke the ice a bit, and now they were just... chilling.
When it came to the two of them, it was usually Marceline popping in unannounced—and if he did come over to her place, he usually had Jake in tow, or PB. Don't get her wrong, she liked the kid, they were tight as a knot, but it had been a while since she and Finn hung out one-on-one.
It came off as a little odd, to be honest. But Marceline wasn't going to ambush him about it, if he had things to talk about he would talk about them on his own time.
Light, ambient music filled the house as Finn switched her stereo on, slumping back on the couch with a little sigh, spreading himself out over the firm red cushions. Meanwhile, Marceline was floating aimlessly about her kitchen, the shutter to her little "bar" area open, allowing the calming electronic music inside. The vampire girl swayed about in the air, her long black hair flowing behind her as she let the beat dictate her movements, grooving along without a care. At times, Finn would glance her way, and they should share a smile—hers had a more playful edge, while his was more muted.
Marceline twisted around in the air and drifted towards the bar, poking her head through that window into her kitchen and leaning over the counter. "Hey, Finn? What do you wanna drink?" It was a good thing that she kept the counter clear.
Wrapped within the tight confines of an enormous dark gray t-shirt with a teddy bear on the front was a gargantuan pair of tits, which leapt through the window and THWUMPED loudly across the counter. They spread across the flat surface, filling up the space between the open shutters from end to end, even outgrowing it, as those swollen milkbags bulged through the frame, across the counter, and spilled over the edge of the counter. Marceline's horizontally floating body looked tiny in comparison to those beanbag chair tits. Each one was easily larger than her head, torso, and a good portion of her lower body combined. Those smooth orbs of gray fat eagerly spilled from her shirt, exposing what seemed like acres of cleavage eager to escape the prison of dark gray cloth wrapped snugly around them.
As a young man in the cruel clutches of puberty, it was no surprise that Finn's brain stopped functioning for a few seconds. "Uuuuuuuuuuuuuuuhhhhhhh..."
Marceline was no fool—she was more than aware of the effect her body had on the poor lad, and could only smile playfully, crossing her slender arms atop her cleavage and pressing down on her freakishly huge tits, shifting them around and causing more to bulge outwards to either side. "Everything working up there, little man?" she asked with a snarky tone.
Seemingly realizing his mistake, Finn turned his head away, brushing a hand across his fluffy white hat and finding himself very interested in a random stain on the ceiling, doing all he could to keep his eyes up and away from Marceline. "Oh? Uh, yeah… I'm… uh… just a soda's fine… I guess…" He squirmed in place and tugged on his shorts a bit, causing Marceline to snort under her breath.
"Cherry soda okay?" She asked, receding through the shutter, her massive tits briefly getting caught on the edges before they popped out and bounced back into shape, heaving up and outwards before coming back to a rest with a meaty whap against her ribs. The only response she got out of Finn was a barely perceptible, affirmative grunt. Poor dude. Being perpetually youthful had its benefits, but plenty of drawbacks. Like having to grapple with puberty for way longer than anyone deserved. So she could sympathize with him.
Maybe that's why he came by? Marceline thought to herself, fluttering through the kitchen towards her fridge. Bit rude of her to be presumptuous… and maybe a bit egotistical, but Finn had had it rough with girls for a while now, and at such an important time… Poor guy was probably grappling with a lot of feelings and urges he had no idea what to do with. Tight sweatpants audibly strained as Marceline bent forward, rummaging through her supply of drinks, her tiny socked feet dangling in the air as she wiggled her enormous ass back and forth.
What were meant to be loose sweatpants were stretched taut around a plentiful heap of vampire cake, each cheek more than enough to smother Finn's whole body, and making her skinny little body (sans those massive breasts, of course) look comically small by comparison. That shelf jutted out several feet from her body, wobbling freely, smoothly transitioning into obscenely wide hips and a pair of thighs thrice as wide as her own torso. It was probably one of the fattest asses in all of Ooo, only rivaled by Princess Bubblebutt herself, who had Marceline soundly beaten…
Which was just fine with her—given that just meant more Bubblegum to love, squeeze, spank, and nibble on! Still, it left Marceline with a ridiculous hourglass figure and a fat, wobbly ass that refused to stop moving. Even the little wiggles of her hips to the beat of the music sent ripples flying across those massive globes.
Cherry soda obtained, Marceline forced herself upright, drifting through the air with two soda cans in hand and confronting the tiny door leading into her kitchen. After nudging it open, she twisted through the air, floating horizontally and on her side just to have a chance at fitting her ass through that narrow gap. Even then, her jutting cheeks and her humongous tits caught against the doorframe, causing a few unfortunate bumps that no doubt called more attention to the vampire queen's figure.
When Marceline returned to an upright position, one could draw a direct comparison to the width of her hips and thighs to that teeny, tiny doorway she had just squeezed through. On top of all that, of course, she was unbearably pretty. Soft black eyes, cute lips, long hair, and those alluringly dangerous fangs always on display. It was no surprise that Finn was nervously tapping his palms against his thighs and leaning his head back just to stop himself from looking at Marcy.
There was temptation to tease him a bit more, to wiggle in his face, or just rub it in a bit. But she managed to resist the urge, simply drifting over to the boy and offering him a soda, which he gingerly took, opening the tab with a soft hiss. Marceline followed suit, leaning back and downing some of it, swishing it around in her mouth until her fangs could suck up all the red. After an awkward silence, Marceline drifted towards the couch and absentmindedly gestured for Finn to scoot.
The boy barely had time to react, frantically scooting to one side of the couch, as close to the edge as he could possibly get, and even still it was not enough to stop Marceline's hips from squishing against his comparably tiny legs, and her thighs to push outward and try to force him off. Finn had to hold the side of the couch just to stop Marceline from knocking him off, a fact which probably should have distressed him more than it did, but the poor dude was too busy turning red all over to care much about falling off the couch.
Lounging back, with her enormous breasts spilling over her thighs and wobbling into Finn's personal space, Marceline lifted an arm and wrapped it over the back of the couch, idly sipping from her soda can as she watched all sorts of emotions play over Finn's face. Every so often he would take furtive glances in her direction, only for his eyes to shift away the moment they caught a glimpse of her body.
Twisting her finger along the upholstery, she crossed one leg over the other, feeling mixed at his reaction. On one hand, it was kind of adorable. On the other hand… obviously he was having problems. Poor dude looked like he was about to explode, and he wasn't in a hurry to tell her why he decided to show up. He just took nervous sips from his soda and kept staring off to the side, his knee bouncing more and more with nervous energy.
Marceline pursed her lips, "*Soooooooo*…" she propped her elbow up against the couch and leaned her cheek against it, even the slightest movement causing her oversized tits to jostle around in his view. They were so huge, and took up so much space that it was becoming difficult for Finn to find a place to stare at that *didn't* give him a glimpse.
"What's up?" she asked with a knowing smile. "Cus you can just keep sittin' here all nervous… and pretend like you aren't on the verge of exploding… or we can talk about it, and I could maybe help you…?" What help meant in this context, Marceline had no idea. A hint of warmth spread through her ice cold cheeks as she began to realize what that might imply, but she kept it cool. Finn needed someone confident right now, not someone nervous and thinking she was about to do something messed up but kinda hot.
Finn slowly tilted his head to the side, gritting his teeth as he turned to meet her gaze, his shoulders and legs bunching up tightly, his whole body hunching over and curling up like a pillbug. "… Uh, it's just… y'know… I just wanna hang out…"
"Finn…" Marceline glowered at him, reaching over and poking him on the head. "The only thing you've done since you got here is stare at my boobs. More than usual."
"Not true… I stared at your butt a bit…" Finn blurted out, before smacking his palm over his lips with a girlish squeal.
Marceline started to giggle at that, covering her mouth in some vain attempt at fighting them back, only for them to keep snorting out, much to Finn's complete and utter embarrassment. The boy was on the verge of shutting down completely when Marceline reached out and jostled him by the shoulder. "Snap out of it, Finn… It's cool, it's cool… I'm just… worried about you, man. You look all wound up, and tense…"
Slowly unfurling himself from his own body, Finn leaned back with a deep, deep sigh, crossing his arms over his chest and letting out a sputtering, exhausted breath. "… It's just… y'know… I'm bustin' my butt bein' a hero, and I don't get much time to relax… Jake and Lady are off doing their own thing half the time, and meanwhile I'm here like…" Lacking the ability to put his emotions into words, he just gave up and blew a sad little raspberry. "My body's doing things to me and all I can think about is girls, girls, girls… and like… ugh… this is getting TMI…"
Feeling a little blush creep up on her cheeks, Marceline slooowly wrapped her arm around his shoulder, nestling just a little bit closer and engulfing half his face in her cleavage, those soft pillows brushing against his face just enough to make Finn begin to babble and squirm. "So, what… why'd you come to me, then?"
"C-Cus… you're cool… and, uh… you know, you don't usually… get all up in arms about this stuff… and you know… you're easier to talk to than pretty much every other girl I've met…" It was a miracle he even had the brain power to speak, the proximity of Marceline's bust making his chest rise and fall, his pupils dilate—activating primal urges inside of the young boy and causing his trembling hands to rise.
"Awww…" Marceline smirked at him, teasingly reaching over and tickling under his chin. "That's cute. But what were you expecting to do after you talked to me, dude?"
"I'dunno, I just…" Finn grew more flustered, "Figured you'd give me advice, or… teach me how to make girls happy, or… something…"
"It changes from girl to girl…" Marceline said softly. "You just gotta… talk to them, get to know them… know what they like, and care about what they say… that sort of thing. Sometimes it just doesn't work out, or sometimes they don't like you back no matter what ya do…" Marceline huffed, "But like… if you can't even get past staring at a girl with big tits, you're probably not gonna make it that far…"
"Feels like all my brain juice goes between my legs…" Finn muttered tugging on his hood a bit, a small tuft of blonde hair poking out. "The heck am I supposed to do if I can barely feel my legs when I… uh… look at you?"
"Obviously you need some hands on experience… get those nervous jitters out, y'know? Get used to it…" Marceline closed her eyes and took a deep, deep breath. Was she really about to do this? Jeez. She would have to apologize to Bonnie later, but this poor kid was going to explode without her help…
Marceline scooted a little closer, wrapping her arm around Finn's waist and bringing him in, letting even more of her cleavage engulf his comparably tiny body, heaps of boobflesh cascading over his shoulders and arms. Finn seemed to freeze for a moment, before Marceline leaned down and whispered softly. "Don't tell anyone about this, kay? Promise?"
Finn's expression grew serious—his eyes wide, and his lips trembling. "P-Promise…"
"Touch 'em… come on. Go ahead…" Marceline wiggled her shoulders side to side, heaving those massive tits to and fro with Finn trapped against them, letting them wobble and smack against his body. It didn't take Finn long to get the hint, hesitantly raising his arms up and brushing them against the outer edges of her enormous bust. The fact that he could climb on top of them and snuggle into them like a big bed made Marceline flush even hotter. It was cute… seeing his tiny little arms squish into the sides, wedging deeply into them, rolling and squeezing at them with a look of utter amazement in his eyes.
"Woah… they're way softer than they look… algebraic…"
Marceline cooed softly, letting out a playful giggle as she felt his tiny hands kneading across her massive tits. "… Uh-huh… they're pretty great… and it feels good when you touch 'em, too...~" She brushed her long, black hair aside, making Finn clam up as she leaned forward, letting off a low, and husky moan as his arms pressed inwards and squeezed them together. The shivers that ran up Finn's spine after that made Marceline swell with confidence. And it made something swell underneath her, as well. A lump pressed up against her thigh, poking through his incredibly tight short. It was… big. Really, really big. Like, kinda ridiculously big considering his crotch seemed flat when he walked into the room?
Marceline huffed a bit. "Oooh… hey, what's that?" The vampire bared her fangs at him, a knowing, playful smile on her face as she started to scoot back, finding Finn reluctant to part with her chest pillows, but managing to pry him off of her long enough that she could slip behind him. Finn let out a little gasp as Marceline pulled him into her lap, bracing her hands across his hips and letting him lean back into her massive bust like a bed.
"H-Hey, hey… Marcy… what's up…?" He asked, kicking his legs nervously, "… That's kinda… uhh… uhh… a sensitive area…"
"Yeah, it's sensitive alright—and it's how you make girls feel good… when you're… beyond the making out part of the relationship, at least…"
"But we haven't even made out yet…" Finn muttered innocently.
Marceline giggled, sighing softly as she placed a little smooch on the corner of his neck. "Yeah, I'm doing this 'cus I'm your friend, not cus I wanna date you… so we're skipping that part and getting straight to the part you really need right now…" She tugged on his pants a few times, finding them surprisingly stubborn. Hell, it felt like they were painted on… They were so tight, yet it felt like they were holding back something unbelievably heavy. Thinking that she would be able to tug them off with ease, she kept working at it, and no matter what she did, they refused to budge.
Finn kicked his legs out, squirming in Marceline's grasp as each tug caused him to tense up, his teeth gritting and his eyes lidding slowly. "H-Hey... Marcy... s-slow down..." he whined, the lump in his shorts steadily growing with each tug until it was nestled between his thighs and starting to spill further and further out. Each time she tried to pry those teeny, tiny shorts off, it felt like he was growing bigger, and bigger...
Finally, Marceline got fed up, her eyes widening as she peered over Finn's half-smothered head and ogled that ridiculous bulge that had appeared between his legs, as if by magic. "Hey, Finn, the heck is up with your shorts, dude?"
"They're magic, or somethin'... needed them cus my old pair got too small, and it was gettin' in the way..." Finn took a deep breath, his voice quavering as he exhaled, his body sinking even deeper into Marcy's cleavage. She let out a surprised little coo as he reached his hands up and wrapped them around the underside of her massive boobs, squeezing them tighter around his body. "... There's, a uh, release phrase..."
" It ?" Marceline raised an eyebrow, glaring at that tightly packed bulge. "What's it ?"
Finn managed to lean his head back enough that he could look up at the much taller girl, his cute little face poking out of her cleavage, idle gropes and squeezes rolled around that body-smothering bust of hers while he could barely mutter out an answer. "You know... my, uh... you know?" Marceline blinked at him a couple times, causing Finn's face to grow even redder. "Come on, dude... don't make me say it... I'm gonna die of embarrassment over here..."
"Your dick ?" Marceline glared at the lump in his pants incredulously, a smile creeping up on her face that was a mixture of dumbfounded and extremely amused. The vampire leaned forward, heaving her bust into Finn's face even more and causing the boy to tilt his head to the side so he could clear his airway. A pale finger poked against it, a giggle slipping from Marceline's smiling lips as she glanced back at the half-smothered boy. "It was too big ?"
Finn looked mortified, his eyes widening and his mouth hanging open, as he let out a frustrated grunt. " Uuuugh , how else do you want me to say it? Don't laugh at it..." He kicked his legs a bit, causing Marceline to snicker as she smoothed her fingers down his thighs to calm them down—unsuccessfully, of course, since such a gentle and cool touch from such soft, girly hands did nothing but make his poor hormones go wild .
"Calm down, dude... I was just giggling to myself... I've heard a lot of dudes say stuff like that..." Marceline grinned, raising her eyebrow as she watched that enormous lump twitch and throb. "But something tells me you're being honest here... how you been dealing with this thing little bro~?" With a casual sigh, she slipped forward, her humongous tits pushing past his face and instead cascading down his skinny chest. Thin arms with only the slightest hint of developed muscle pushed up to hold them but were quickly overpowered by their sheer weight.
Finn grunted laboriously, his eyes widening as he watched her swollen chest roll over his body, settling around his waist with her hanging cleavage nestled right above his crotch. The awkward angle also meant that Marceline's butt was nestled right beside his head, her long and curvaceous legs kicking upwards into the air with playful energy. "I just sorta grab a bunch of pillows and... uhh... grind on top of them, use my hands a bit..." He muttered, his comparably tiny hands compressing that thin, soft fabric inwards as he sank into her supple boobflesh, a soft and gentle breath accompanying his experimental grope.
"Ooohh... that big, huh~?" Marceline's long, thin tongue flicked out of her lips, her cheeks wiggling with excitement, her overstretched sweatpants doing little to stop those meaty cheeks from heaving together and clapping right in his ears.
"Hahhh... is... uh... do girls like... big ?" Finn asked nervously, letting his hands explore the outer edges of her impossibly huge bust, dragging them along the sides, soft and pliable boobflesh spilling from his arms as he dragged from tip to base, before letting go and allowing them to hang and squish against his bulge. He breathed heavily, his legs tensing every half second or so in rhythm with the concerning sounds of his shorts stretching taut around his overbearing erection.
"Oh, yeah..." Marceline brushed a fingertip along that angry lump, glancing back up with a wry smile just so she could see his reaction.
"Y-Yeah...?" Finn's eyes fluttered a bit, his teeth gritting together while a shuddering breath filtered through with a soft hiss .
"Some more than others... but yeah, most girls like 'em big... lot of weirdos in Ooo like 'em gigantic . Lots of weird monsters, magicians, and stuff to compare to... you're looking like my type, right now~" Marceline continued to stroke her single finger up and down that lump, relishing her chance to tease a poor, inexperienced virgin. It brought back some pleasant memories.
A powerful pulse ran through it, one that was so powerful that Marceline swore she could hear it. The blood rushing through his veins at such unbelievably pressure that it felt like he would burst like a balloon. Finn stretched his arms and legs out with a groan, a concerning stttrrrrtch! ripping through the room as that grapefruit sized lump suddenly expanded to the size of a watermelon.
Marceline stood there with her mouth agape as what had been a simple round lump now took on more detailed characteristics, choked tight and curled up within his shorts with such unbelievable tightness that it could only be magic. "... Hahh... this... this how big you actually are?"
There was an ear-grating noise as Finn's nails dug into the upholstery, dragging across it while his legs shot out to either side, their sudden movement sending her melons jostling about right against his now constantly twitching bulge. "N-No... no... uhh... no... this is... uhh... oh, that's really tight..."
Finding it hard to believe he could get even bigger, the vampire reached a hand up and brushed her hair to the side, finding her undead heart skipping a beat at the idea it could get even larger . "... This feels good~?" Marceline brushed her finger all the way up that huge bulge and twisted it around the tip. "Yeah, it's pretty tight... that's why guys are so obsessed with girls, y'know...?"
"N-No... I mean... it's really, really tight..." Finn's face was starting to turn red. "... Urgh..."
"What?" Marceline blinked.
"It needs a really powerful spell, and ugh... when it starts getting big like this it starts to hurt a whole lot... it usually doesn't get this bad, but... nnghh... you're so... cool... and hot, and stuff, Marceline..."
Marceline slowly floated up, nestling into the couch beside him and allowing her legs to slip over his lap, cradling his head in her arms and drawing him in, letting his chin rest in her plentiful cleavage. "Shut up dude..." She muttered with an amused grin, finding it hard not to blush when a cutie like him was gushing about her. "You should probably tell me that release word already, before you explode...~"
It was totally out of concern for Finn's well-being and totally not because his phrasing had piqued her curiosity. But really, Marceline's mind went wild with speculation as she tried to imagine what this kid could possibly be packing down there to require magical shorts to keep it under control. But she wouldn't have to wait long to figure it out.
Finn breathed deeply, before wheezing out. "Skizazzle Skizoff, I want these pants off!"
She was not expecting the shorts to zip right off his legs like a rocket—they were attached to him one second, and plastered against the wall in the next. The sound of it was like a whip cracking, startling Marceline enough that she grabbed Finn by the head and stuffed it into her cleavage, forcing herself into a sort of bridal carry with him. Of course, she was floating; there was no way Finn could carry Marceline on his own.
THWUMP !
Every knick-knack in the living room rattled on its shelf as something weighty smashed down on the carpet, followed almost immediately by something else slapping atop it with a meaty FWAP . A warm sigh of relief washed over Marceline's cleavage as the tense young boy seemed to sink back in his chair, no longer constrained by his magical shorts, and it was obvious just from one look that they had been working hard to keep him under wraps.
A slab—no, a trunk of meat forced his legs apart, so unbearably thick and fat that Marceline could wrap her arms around it and cuddle it if she wanted to. Sweltering heat radiated from it, every twitch causing it to fatten up and rise from its resting place atop a pair of gargantuan balls. Each were easily big enough that she could splay out across them like the beanbag chair in her bedroom, forcing Finn to prop his legs atop them thanks to his lack of legroom.
A pulse ran through it, from the fat base across his bulbous shaft to the slightly thinner mushroom-shaped tip, rosy and red. A heavy, and cold breath followed as Marceline took in the sight of it, and found her initial shock quickly turning to a wide, ecstatic grin.
" Duuuuuuuuude ..." Marceline slowly pulled away from Finn, unfurling her arms from his shoulders and pulling back, releasing the blushing, panting boy from her prison of cleavage. He was reluctant to go, leaning his head forward to remain in their cool embrace until she drifted far enough away that they bounced back into their natural resting place.
She twisted through the air alongside the length of his cock, stretching her legs out fully and keeping her arms to her sides, a big, dumb smile on her face as the realization dawned on her. "It's taller than me !"
"Is that... bad...?" Finn asked curiously, the comical sight of his tiny, thin body attached to that monster easily taller and wider than he was becoming more comical by the second. Finn could live in his balls, they were so huge.
Marceline giggled softly, drifting over the shaft and placing her arm next to it just to compare the thickness—it wasn't even close, and as Finn watched her float beside it, smiling, fawning over it, it would only get longer and thicker. Little dude wasn't even fully hard yet. Her undead heart was racing with excitement as she drifted over, her tits hanging pendulously in front of his face as she drew closer.
"Dude... you're huge. Like... stupid huge... no, no it's not bad at all~" Marceline snickered, "If you had swung this thing around at me, movie night wouldn't have been so awkward, y'know?"
"Jake says I'm not supposed to do that..." Finn muttered sheepishly. "Says only freaks and weirdos go around doing that."
"And he's totally right—but seriously, dude... what the heck? Where you been hiding this thing from me~?" Wetting her lips as if she were about to dig into a feast, she drifted closer, causing the babbling boy to clam up as her nose snuggled right up next to his before she tilted her head and planted a smooch on his lips.
A soft hand brushed along his cheek, causing him to absolutely melt in her grasp, closing his eyes tight as he grew unsure of what he was supposed to do. But Marceline helped him, settling into his lap with her enormous cheeks wedged around his thick shaft, heat and arousal burning through her cold nerves and reactivating them as she felt it twitch and throb. The sound of his heartbeat vibrated through her body, as her globes ground back and forth across it and her legs straddled his tiny lower half.
Soon, she pulled back, cooing softly as she did and smirking at him.
He looked her in the eyes, innocent, excited, beyond stoked but also shy enough to bottle all that up. His voice cracked a bit as he spoke, "I thought you said we weren't doing makeout stuff...?"
"Yeah, that was before I knew your dick could wear me like a sock. You gonna keep arguing, little bro, or would you rather I teach you what "friends with benefits" means~?" Marceline breathed softly, stroking his cheek slowly and feeling his face warm to her touch. All he could muster was a curt and very small nod.
After which, she leaned in and stole another kiss from his virgin lips—and this time, she broke the one and only rule she ever gave him. Finn let out a delighted whimper as her cool tongue slithered past his lips, hogtying his own little tongue and dragging it out into the open. She went to great lengths to teach him, straddling and smothering him, letting him feel her weight pressing down on him as she trained him up.
A few awkward tangles here and there, and they were making out like the best of them, soft smacks of their lips and feverish breaths breaking up the soft slurps of their entanglement. Her tongue writhed inside of his mouth, and she might have gotten a little freaky and stuck it down his throat a couple times, a slimy, wet smack filling the room as she parted away and moved her hands down to his shoulders.
"Okay... so you got that part down pretty good, but don't just sit there, dude... you gotta touch me...~" Marceline reached up to brush her long hair away from her eyes and smirked down at that boy, who looked like he had just seen heaven, and had been forced to come back down to the Earth.
"I don't know what to do with my hands..." Finn admitted softly, his fingers trembling as Marceline reached down and grabbed him by the wrists, smiling at him the entire time as she dragged them over to her bust and let him sink his palms into them again. "... T-This... this is okay, right?"
"Not really, but I won't tell anyone if you don't~" The mortified look on his face made her snicker, before she leaned forward, letting her huge, gray milkers squish around his arms and steadily devour them like a hungry slime. "Lighten up, dude... Look, here's how it works... if a girl is kissing you like that, and she's grinding against you like this ...~" Marceline worked her hips back and forth, biting her lip and cooing as she felt that fat cock pulse between her legs. "... You can be pretty safe and assume you can touch her wherever... trust me, once you're here... the worst I can do is tell you stop and touch me somewhere else...~"
Finn bit his lip, "... What's good to touch, though...?" He asked softly, brushing his palms along her bust, delightful tingles radiating through them with each curious squeeze and experimental heft.
Marceline sighed and leaned forward, nestling her forehead against his, letting her hair drape down over his face like soft silky strands of fabric, her back arching as her tongue slipped across his lips with a playful flick. "Anywhere, dude... Come on, if I list it out like an ecyclopedia, it's gonna get boring... just... be gentle... stroke me... squeeze the soft parts..." She trailed off as she leaned closer again, catching his lips with hers and dragging him right back into her embrace.
This time, he was quick to get moving, one hand remaining planted on her body-engulfing tits, sinking down to the elbow and even past that as he drew a valley into her boobflesh, squeezing along the side until he found her waist. A surprising tingle ran up her spine as he massaged along her waist, running up and under her armpit, before roaming up her neck and beginning to stroke along the side of her neck. The other hand nudged against her breast, elbowing it out of the way and dragging underneath it, finding her waist again and moving to the back, steadily dragging along the contours of her spine until he found the swell of her hips and the enormous shelf of boy-smothering booty grinding against his cock.
It must have been doing a lot for him, as he had grown by now, his cock just barely beginning to hold itself up, so unbearably thick and heavy that he could have pinned her down underneath it if he wanted to. It was easily taller than she was now, so unbelievably hyper huge that it was almost laughable. Poor dude would scare more prudish girls off, but just feeling it pulse and throb underneath her made her undead body flush with warmth, something that only Peebles had ever managed to do.
That, and Ice King's weird and extremely risque drawings of a female version of himself that he had hanging up in a secret chamber but she would rather not think about the implications of that right now.
Marceline raised her arms into the air, cooing into their deep kiss as his tiny hands had just begun to glide along the outer edges of her cake, dragging along the overhang of that firm and unbearably heavy pair of globes and mashing them together, her loose sweatpants doing little to stop him from burying himself down to the wrists... A delightful surge of arousal filled her as his cock lurched and let loose a pungent-smelling gush of fluid, so thick and so plentiful that she could hear it hitting her carpet. She didn't even have to turn around to know that thick globs of mostly translucent pre were leaking down his monolithic cock.
"Ahhhmm...~" Marceline went in deeper, her tongue twisting around in his mouth and her fangs grazing dangerously across his lips, causing one of his hands to jerk upwards and tug at the bottom of her top. That spurred her into leaning back, heaps of gray flesh cascading out from the bottom of her top as he tugged it tight and wrapped it firmly around her jiggling melons.
Finn breathed heavily, out of breath and panting by the time that Marceline pulled away. But she didn't pull all the way back, leaning her head over and whispering softly in his ear. "Flip it up...~" She hissed in a challenging tone.
There was no hesitation anymore, he hooked his thumb under her shirt and flipped it up, watching as it briefly caught against the abundance of boobflesh spilling out, before their weight became too much and caused them to come flopping out into the open. Each larger than his own torso and head combined, and each capped with a dark gray nipple thicker than his fist. Thick, puffy areola were eagerly gripped by the young boy, who's eyes nearly flew out of his skull at the sight.
"Nhhghn...~" Marceline rolled her shoulders back, adjusting her position so she was leaning back and giving him full access, taking a moment to brush her hair back as he refocused his efforts on her melons. Both hands nestled into them, mashing those huge tits together and bulging those pillowy tits out between his thin little arms.
"Suck on them..." Marceline urged.
"Ah..." Finn opened his mouth hesitantly, hefting up one of those immense tits and slurping up one of those fat nipples with a joyous squeak. A soft slurp escaped his lips as he engulfed that juicy teat in his lips, all that shyness fading away as soon as he got a taste of it. A pleasant, red hot breath burned against her breast as he dove headfirst into her boob, so deep that her breast started to mold around the shape of his head.
"Ooohh... that's a good boy..." With a little snicker, she finally got a chance to look back, and felt a tingling deep in her core when she saw that monster sitting behind her. Feeling it against her backside was one thing but taking in the full sight of it was something else. Just imaginging that thing inside of her made her stomach twist into pleasant little knots. But that was okay, he would be straightening out her guts pretty damn soon...
The other hand reached down to her lips and started to glide along her thighs, tracing around the hem of her sweatpants... and she suddenly jolted as he slipped between her thighs. A twinge of excitement followed before she reached down and took hold of his wrist, biting her lip and showing off her fangs as he froze.
"Ahhhn... don't get ahead of yourself little dude... That spot's reserved..."
A soft gulp, and a slurp left his disappointed lips as he pulled back, letting her breast flop from his mouth before wrapping his arms around them and sinking so deep he could press his chest against hers. "How am I supposed to, uh... do... that, then? C-Cus I thought, you know... you needed... that... to do sex..." Finn grew more unsure and more embarrassed the more words he spoke, which only made Marceline smile wider, her hand reaching out and sliding underneath his white hood to stroke the pretty blonde hair underneath.
"... More than one way to lose your virginity, little bro...~" With a wry smile and a playful jerk of her head, she started to float out of his grasp. "Gimme a sec..."
Finn watched with interest as Marceline rose away from his lap, dragging her entire ass along his length and roughly coutning the feet as she drew closer and closer to the ceiling. She stopped feeling it brushing against her around the seven foot mark, wondering how this kid could even be conscious with a monster like that. But it only got her more excited. She twisted around in the air. "Scootch up...~" She beckoned towards him, waiting for Finn to awkwardly shuffle his butt forward on the couch until he was sitting on the edge, causing his balls to slump loudly against the floor as he got settled.
Then, her feet braced against his balls as she descended, her cool skin brushing against those burning hot orbs as she settled in his lap again, but this time... she was facing away from him. Bending forward, Marceline stretched her arms overhead and lounged across his massive cock like some kind of hammock, kicking her legs up briefly before she arched her back and thrust her massive ass right in front of his face, her body-devouring cheeks filling up every inch of his view and then some.
With a snicker, she tugged at the corners of her overworked sweatpants and began to slide them down her immense hips, thigh and booty bulging out from the fabric little by little until she could slide them down her calves and kick them daintily off her feet. Bare vampire booty was presented to the horny teen, his eyes bouncing up and down like a basketball to the rhythm of her cheek's constant jiggling.
A powerful lurch of blood rushing through that monster caused another gush of pre-cum to spray from his massive cockhole, splattering against the floor and trickling down his engorged shaft like a waterfall. The soft, and cool embrace of Marceline's milkers nestled lovingly around his shaft, wedged around them and just barely managing to envelope his unbearably huge girth. She wiggled her shoulders, nestling her arms against the sides and gliding them up with a little coo, before slapping them down and together with a little huff. "... Oohh... gotta make sure this thing's nice and lubed up before we get to the fun part, or else this is gonna hurt like a bitch...~"
"What's... gonna hurt...?" He asked softly, practically hypnotized by the looming moon hanging over him.
"Ooh, right... hey... do me a favor...~" Marceline thrust her hips back a little more, her cheeks clapping together mere inches from his face like a steel trap ready to ensare him. "... Spread those cheeks and pretend you're making out with my butthole, kay~?"
"W-What...!? That's... like... really gross!?" Finn pursed his lips a bit, despite his eyes and his trembling hands telling another story.
"I'm a vampire dummy, I don't poop. Plus I keep it clean for Peebles. Don't be such a baby... I'm scratching your back, you scratch mine...~" Marceline nestled her cheek against that flush pillar of flesh, taking in deep breaths as she rolled her entire body up and down, feeling it glide from the top of her forehead all the way down to her belly button, shuddering at how it twitched and pulsed. The movement also served to teasingly wiggle her ass right in his face, no doubt making it harder to refuse her order.
After only a moment of thinking it over, Finn pressed his tiny hands against the canyon of deep, deep bootyflesh and pried it apart, digging deep into the walls of her cavernous crack until he could just barely see the tight and twitching ring of muscle buried within. "... Just... pretend to make out with it...?" He muttered softly, more like he was trying to convince himself than questioning her.
But he gave it a shot—the little dork's head disappeared between her cheeks and feeling that warm, living flesh snuggled nice and tight between her ultracake was a pleasant shock to the system... and so was feeling his hot, panting breaths against her delicate hole, and his tongue twisting and lapping at it curiously. The soft, and tender skin and the not at all unpleasant feeling of wriggling his tongue around that twitching hole must have been convincing enough cus he was going for it now.
"Uuuuhhnn... yeah...~" Marceline pressed her legs together, trying her best not to squish Finn between her thighs, even if she could feel her delightfully neglected pussy aching for some attention. But that was the sort of thing she liked, that pleasant, tingling sensation of his tongue running over her asshole, his lips suckling on the corners and probing inside. All that hot, warm saliva glazing her quivering donut. Fuck... Marceline dragged her massive tits along his telephone pole of a cock and moaned out load, her long tongue slithering along one of those huge veins as she felt the first warm globs of pre-cum finally start to ooze down the front.
It was perfect, just what she needed to get the ball rolling. Marceline slurped up some of that gunk, the pungent smell and salty taste awakening instincts within her that she hadn't indulged in quite a while. The slick smear of pre-cum across his immense cock was easy to spread with her fat tits, steeped in his constantly-leaking pre-nut, shlicking softly as she jerked her entire body up and down its impossible length.
Her cheeks engulfed his head and shoulders and most of his chest, as she leaned back and felt them squish against the back of the couch. His arms no longer worked to spread them, merely squeeze and massage them, taking big firm handfuls and jostling all that meat around while his tongue worked deep. He slobbered all over her, which was just what she needed, fluids leaking from between her thighs and not just from her hungry little friend, but from her own growing arousal.
"Ahhhn... fuck... dude... I want this thing to split me in half...~" Marceline groaned softly, smiling as she slurped up another big glob of pre-cum and swallowed it without a second thought.
"Mmpppmhmhhh...~" Finn's response vibrated against her asshole and made her legs curl up nice and tight, her eyes lidding as the emptiness inside of her grew too much to bear. Marceline pulled forward, freeing Finn from the grasp of her cheeks, his face sweating and covered in his own spittle, and his eyes slightly cross as he muttered. "... That sounds baddd..."
"Oooh, no, it's the best feeling ever... you just gotta do it right...~" The vampire floated away from him, depriving him of his new favorite toy for the time-being, but she had a feeling that he would forget all about that in a second. She floated up, and up, and up... all the way to the tippy top and slowly guided it downwards, lining it up more horizontal to the ground instead of towards the ceiling. She would need her feet on the floor if she had any hope of doing this.
"... Ahhhn... you said you can thrust your hips with this thing... Pillows, right~?" Marceline's feet touched the ground, and she straddled his swollen girth with her thighs, letting the tip nestle right against her bare pussy, its pulsing and gushing causing a pleasant warmth to fill her insides.
"... Y-Yeah, kinda..." Finn muttered. Imagining this kid with balls as big as he was thrusting his hips was comical, but if he could really pull it off, then she was about to rock his world.
"Okay..." Marceline took a few careful steps forward, shuffling over until his swollen cockhead nestled between her thick, gray cheeks, gushing a few more gluts of pre-cum all over them and leaving them glistening and sticky, before she settled her hands against her glutes and parted them, letting him see that broad cocktip squish against her spit-shined asshole. "Foouhhgh...~" Marceline stuck her tongue out. "... Oh, that's a big... big... big... one..." she grunted.
"Is... is this, uh... supposed to be how it works...?" He asked softly, his eyes wide as he watched her tight ring of muscles expand against his cock, and twitched as he watched her sink down just a couple inches.
"... Not really, but... this is... ughh... one way to do it if you don't want to get someone pregnant... or if you just... like doing it here, instead of your pussy... fuck... and I'm the kind of freak who likes it up the ass...~" Trembling, Marceline put just a bit of pressure on him, wincing as he started to stretch her open right away, his cocktip popping into her with a pleasant shlick and letting her feel that rapidly widening shaft tugging at the corners of her asshole.
"Mmnhhnhnh...~" Marceline's huge tits flopped against her thighs as she bent forward, whimpering and shaking as she worked him down inch by painstaking inch. Finn groaned, rolling his hips forward and shunting that entire thing forward a couple inches, making Marceline squeal in delight as it lurched forward and mashed against the walls of her stomach. Her flat belly button poked out to an obscene degree, squelching as more than a foot of cock lodged itself into her deepest reaches.
"F-Fuck... fuck... fuck...~" Marceline whimpered, placing her fingers over her gushing lips and stroking her arm against the side of one of her tits, groaning as she squished down, taking a few nervous steps back before hammering it down with another loud SQUELCH !
"This sounds really... really dangerous..." Finn huffed, his chest rising and falling rapidly, his balls churning with a fury that Marceline had never heard before in her life. His face was flushed red and his little hips looked like they wanted to shoot forward like a rocket with how tense they were. Just feeling her guts getting hosed down with pre-cum was enough encouragement to jam another two feet into her belly.
Despite her belly button spreading her tits apart and nestling against her cheek, Marceline could turn her head with ease, looking as casual as a woman half-impaled on four feet of cock could be. "Naaaahhh... you gotta lighten up a little, Finn... it feels good for you, right...~?" She emphasized her words with a little shimmy of her hips, stirring that monster around in her guts, feeling it reshape her insides and brutalize every nerve in her body with just its throbs and twitches.
Finn spread his legs out, gripping the edge of the couch cushions and letting out a deep, deep groan, his little hips shifting forward, inch after solid inch engulfed in that twitching hole. The look on his face was enough to know he was in heaven, he didn't even have to say a word. But he did anyway. "R-Really, really good... My head's kinda... Spinnin'..." He grunted.
"Guuughhhggnnn... fuck~" Marceline flipped her hair back, whimpering as his person-sized girth stretched her poor, aching hole more and more, her tight walls clamping down uselessly around it as he just stretched and stretched and stretched. Five feet, six feet... The bulge in her belly grew taller and taller, twitching and undulating from the constant gush of pre-cum... Before her humongous cheeks were nestled around his hips, causing the entire couch to creak as she engulfed everything from hip to shoulders in vampire booty.
"Then don't worry about me, little man... Uughnn... Can't you tell this feels amazing for me, too~?" Every word out of her mouth was a moan, every little shift and nudge of that monster inside her guts reigniting long dead nerves and driving her up the wall with ecstasy. "I'm not moaning like this for the fun of it, you know~?" Panting softly, she whapped back against him, her massive ass heaving outwards and SMACKING around his body with enough force to cause the entire couch to creak.
"Come on, Finn... Hahhh... Come on... If you can carry this thing around, you're strong enough to fuck me... I want you to wreck my asshole..." She hissed softly, squeezing her breasts in both hands, shuddering as she ground herself against it. "... I'll show you why girls like big dicks... Nnhh... I'll cum without even using my hands... You just need to hop up and get to work~"
Those words seemed to spur the young hero on. Finn reached up, huffing, panting, his entire face red and his legs trembling. The young boy, a tuft of blonde hair poking out from his hood, stood shakily on the couch. His humongous balls easily bigger than his short body rested heavily on the floor, and his comparably thin legs looked like they could do nothing to shift that beast attached to him.
But he quickly proved that assumption wrong, as he scaled Marceline's mountainous ass, bracing his ankles against the sides of those firm and jiggly cheeks and hefted himself up with a boyish squeal. A loud, and devestating SHLIIICK filled the room as several feet of cock were forcibly wrenched from her asshole all in one stroke, only to come hurtling back down with the force of a hydraulic press, her asshole stretching back only to be pushed back in all in one smooth motion that culminated in a wet, stretching SCHLAP! His enormous nuts collided with her cheeks and thighs with such force that it sent ripples flying across them for entire seconds.
"Fwuuuhhhhhnnn...~" Marceline whined, holding her arms out and resting them on either side of her monolithic belly bulge. She hugged it tight, feeling it shift and lurch between her arms as Finn found himself a rhythm. A heart-pounding, mind-melting rhythm of three feet leaps that caused gushing pre-cum to schlop out of her tightly-sealed asshole only to spray out in thick gushes as all three feet buried itself down to the hilt, burying Finn's tiny body between her cheeks and spanking her with those massive balls. Over, and over, and over again...
The vampire's eyes watered at the searing heat of all that impossibly girthy meat gliding in and out of her, her teeth gritting as she panted desperately, whimpering as her burning pussy lips tingled with an electric sensation. As neglected as they were, it hardly mattered when every nerve in her body was being subjected to a massage from the inside , his enormous, gushing cock tenderizing her, bulging her like a cocksleeve with unbridled ferocity, constant squelches and schlorps from her poor, aching body making it sound like she was in agony.
But it was the opposite—she was in heaven. Finn clung to her backside, the momentum of his thrusts meaning his body was along for the road, his little hips and legs PLAPPING into her as fast as they could. He panted like a dog, big meaty armfuls of cheek bulging around his limbs.
"Ahhhnn...~" Marceline felt electric tingles travel from her core all the way through her body, her back arching and her nerves melting as a full body orgasm wracked through her. A hand squeezed around her massive tit while the other hugged that meaty shaft pistoning in and out of her abused asshole, squirts gushing from between her legs and hitting the ground... Each thrust causing more to burst forth.
A powerful throb coursed through her, and an ominous gurgling sound filled the air as those enormous balls dangling behind Finn's comparably tiny body clenched with intent to fill . Marceline, even nearly delirious as she was from... however long they had been fucking, could tell what was about to happen.
"Oh, fuck... Finn... ahhh... hahhh..." Marceline licked her lips, looking over her shoulder. "A-Are you about to cum...? It's okay... don't hold back... just let it loose, that's why you're doing it here... don't pull out... Just... let it... fucking... out...~" Marceline whined, her legs tensing up as Finn went wild , clinging to her ass like a little parasite while hammering even faster, the constant glugs and gurgles of his megacock becoming louder by the second. Her heart raced as she imagined what it would feel like... But she wouldn't have to imagine long.
A sound like a firehose going off inside of her followed immediately, with Finn screaming out her name. Those enormous balls clenched so tightly that it felt like they were going to pop out of his sack. A bulge ran along his swollen cocktube, and smashed into her belly with the force of a rocket. Within half a second, her belly was already flooded, and the outline of his cock was already beginning to disappear.
Every SPLURCH and GLORP brought with it a surge of thick, white cum spewing out of her asshole like a fountain, his constant gushing and gurgling cock shooting of continuous, heavy bursts of cum that spewed in messy, sticky globs from her ass. More and more it filled her, with a second turning to a minute... and her belly quickly outgrowing her. Sloshing gray flesh fwumped against the floor and spread out across the carpet, squishing against the stereo and beginning to outgrow it, enveloping it and bugling over it until it was squished flat against the wall.
Soon, she lifted her arms, feeling the sides of her belly spreading out across the room, from one end to the other, all while a geyser of cum spewed out of her asshole. Thick, unbearably hot cum flooding out between her and Finn and no doubt causing a minor flood on its own. Marceline quivered, feeling the warmth of all that cum spreading through her body, the strain of keeping it all stuffed inside of her, and the unbearable fullness of her belly growing and growing and growing!
By the time Finn had even begun to slow down, she was already hugging her big, swollen cumgut like a comfy bed. Every inch of the room was filled, furniture pushed back, and Marceline was nearly to the ceiling. Her legs spread out across her smooth, gray gut, no longer even close to the couch they had started on.
Marceline's eyes watered, her face covered in sweat, and her hair an absolute mess... another bathtubs worth of spunk had managed to spew its way out of her asshole, the aftershocks of Finn's orgasm still adding fresh gluts of hyper-virile spunk to the wall. "Ahhhhnnn... hhahh..." She breathed heavily, just beginning to come to terms with what had happened... and she glanced back, seeing the red-faced blonde boy drenched with sweat laying on top of her smooth back and half his body buried between her fat cheeks.
"Hahhhh... hey, so... if you need to work off some steam, hit me up, kay? You got my number..." Marceline smirked back at him
"S-Sorry... about the mess..." He croaked, and despite nearly flooding her goddamn house his cock was still throbbing and hard inside of her.
Maybe it was a good thing he struck out with the girls so much. Marceline honestly wondered if any regular girl could handle him.
"Don't worry about it...~" Marceline cooed. "This... was sooooo fun...~" She licked her lips. "Did you have fun?"
Finn nodded sheepishly, his lips tightening as he let out a small, adorable. "Mhmhm..."
"Then that's allllll that matters little dude... hooohh..." Marceline stretched her arms out and wobbled on her gurgling gut, listening to the sound of an entire swimming pool's worth of cum sloshing around in her guts. "Gimme a bit and I'll see if I can't squeeze another one out of ya... you sound backed up...~"
Finn wrapped his arms around her waist. "T-Thanks..."
"Don't mention it..." She sighed softly, letting a moment or two pass before her eyes opened again, her voice a little more firm. "Seriously, don't mention this to anyone ."
