Finn, feeling bored and a little lonely, idly played games on Beemo as the sun set, not really paying much attention or really invested in what he was doing. At the back of his head, he was vaguely aware that the night was coming, and all manner of fun things and people would be emerging now, but he didn’t really think about what that might mean.
“Finn?” Beemo asked, a touch timidly. “Where has Jake gone?”
“Huh?” Finn said. He blinked. “Oh, you were recharging earlier, you must have missed it.” He shrugged and smiled nicely. “Jake’s hanging out with Lady tonight. He seemed really hyped about it.”
Beemo’s electronically rendered face blinked. “Oh!” She glanced from side to side. “I see.”
Finn glanced outside; not frowning but looking a little more introspective than he usually got. Pretty close to what he called ‘getting soul-searchy and weird’. “Jake’s been spending the night with Lady a lot recently,” he said.
“Oh,” Beemo said. Various databanks were consulted, trends analyzed, and current knowledge of Lady and Jake’s relationship compared with those previous findings. In less time than it took for a human to blink, Beemo thought of all possible conclusions and arrived at the most logical one. “Oh,” she said again. Several pixels below her eyes tinted red, for the look of a blush.
“Hmph,” Finn said, pouting. “Jake won’t tell me anything about why he keeps hanging out. This busts the baby-bunker!”
“Interesting choice of words,” Beemo said.
“Huh?” Finn said.
Beemo said nothing, but looked at Finn a moment longer, wondering if he understood the implication. Finn blinked innocently, faces screwed up into a cute expression of total bewilderment.
Finn shrugged and decided it wasn’t important, and went back to playing video games. Beemo worked with it, deciding to leave the matter be for the present.
About an hour and fifteen minutes passed in this manner before Finn started to get bored, and he hardly even noticed that the moon was rising in the sky, and the stars glimmered beautifully through the clouds, and that night had come in full. “Beemo?” He said after a moment. “What’s sex education?”
“Why do you ask?” Beemo said, trying to keep her voice neutral.
“Princess Bubblegum keeps talking to me about it; she won’t say anything definitive but… I think she’s planning something.” He frowned. “I think I saw her talking to Marcie at the last party we had a few nights ago.”
“Marcie…” Beemo blinked. “Ah! You mean the sexy vampire lady!”
Finn blushed. “Uh… yeah… her.” He smiled fondly; his expression went puzzled again as he thought for a while on how Bubblegum and Marceline had kept glancing back at him as he showed everyone how to dance like a pro, and they’d made giggling comments about how flexible and cute he was. He’d giggled, and it was so nice to see the taller and older ladies smiling down at him. Even if Marceline was really scary sometimes…
He shivered a little. Sometimes, in the night, there were dreams. Scary dreams, of Marceline coming for him, all hunger and ravenous need, and she was so big in these dreams, in her giant bat form…
She could just pick him up and laugh at him no matter how hard he struggled against her hand or how much he cried, and her mouth loomed wide, rimmed with fangs bigger than swords, and all she had to do was just tip him down into her open mouth, and then her throat was pulling him down and everything got dark, and then she just swallowed-
Finn shivered, whimpering a little. Marceline was scary. So sexy it hurt looking at her, nice when she wasn’t playing tricks on his head and just the way she looked at him sometimes made him want to hug her and eat meatloaf with her and play Beemo with her and never ever stop, but she was still scary.
“Beemo?” He said in a hushed voice.
“Yes, Finn?” Beemo said helpfully.
He shivered. “Do you think-“ He stopped. He shuddered again and tried to put some steel into his thoughts. “Do you think Marceline would eat me? I’ve seen her looking at me sometimes, like at my body, and it’s like she wants to…” He stopped, whimpering.
Beemo was silent for a moment. Slowly, as if considering the implications, she said, “I do not think Marceline wants to kill you.”
“Really?” Finn said hopefully.
“I believe that while she would like to consume you, it would not be in the way you are thinking.”
“What’s that mean?”
Beemo started to only wonder how to explain, and was interrupted by a tapping at the window. “Oh!”
A dark shape, tall and big and woman-shaped, tapped more insistently at the window. Finn obligingly got open and walked over to the window, unconsciously swaying his rather womanish hips in his little pajamas, and undid the window latch. With a grunt, he wedged his fingers in there and forced it open.
In a flurry of wind, and a rolling female grunt, a sleek shape in purple and blue slipped through the window, slamming it shut with a careless gesture, and Finn jerked back as Marceline the Vampire Queen floated a few feet above his living room – technically, her living room – and alighted gently on the ground. “’Sup, weenie?” She said, smiling down at the much younger and smaller boy with a mouthful of sharp teeth. She reached down towards him, as if to give him a high-five.
Finn flinched away. Just for a moment, Marceline’s expression shifted, looking like she’d been physically struck. It passed, so quickly he wasn’t sure if he’d even seen it.
“Geez, calm down. I’m not gonna eat you.” Her lip curled up into the ghost of a smile. “Unless you’re for it.”
Finn, even though he wasn’t sure why, winced as heat flushed on his face.
She grinned more naturally. She leaned over and pinched his chubby cheeks. “Stop being so cute!” She said. “You’re tempting me! Naughty little boy!”
“I am not!” Finn whined.
Marceline smirked. “Oh yes you are!” One hand still cupped his cheek, the skin under her fingers still red from the pinching. Her palm slid down, with a tingle like electricity moving through her into him, and braced itself just under his jawline and neck.
Her skin was not cold, all the stories were wrong. Vampires weren’t cold, they were cool, soft and sweet, like a fresh glass of ice on a hot day, or a not-quite-cold blanket on a stuffy night. Finn’s heart speeded up, and her half-lidded eyes opened slightly wider, the corner of her smirk moving up into the beginnings of a more genuine smile.
Nervously, Marceline licked her lips. She looked… hungry. Finn did his best not to whimper.
She gave his neck a quick pat. “So, your bro went and spent the night with his girlfriend?”
“Y-yeah,” Finn said, stammering a little. He nervously touched the spot where she’d touched him. He felt the ghost of the sensations she made him feel, and it felt… nice.
“Does that bug you?” Marceline said, her ears quirked. She turned around, a long and shimmery dress trimmed with the blue fur of a unwary whywolf sliding around her powerfully built form, delicate folds sliding neatly around her long legs, and purple light shined faintly on the material as she moved. She shrugged, the muscles of her round arms flexing like lusty snakes and her shoulders humping up under the sleeveless arm-holes of her dress, and the massiveness of her black hair rolled around like something alive…
Finn, not even thinking that Marceline was intentionally showing off for his benefit, felt his mouth go dry. He certainly didn’t know what ‘arousal’ meant, or he’d know what he was feeling now.
Marceline looked down at Finn, her blue-green eyes challenging. Her strong and thickly-built body flexed, and she winked. Finn unconsciously straightened up, trying to flex even though he was wearing pajamas suitable for a child several years younger.
“You know,” Marceline said. “You’re a plump kid.”
“Hey!” Finn whined. “I’m not chubs, I’m-“
Her finger found his mouth and pressed against his lips, silencing him. “Shut it,” she said, but she was smiling. “I like plump boys. Feels good having a cushion for the lovin’, know what I mean?”
“No!” Finn squeaked, feeling woozy and a little scared and confused, and it was a powerful stimulant for his young mind.
She smiled. “Give me time, you will.”
Suddenly businesslike, she put a firm hand on his shoulder and pushed him forward. “Beemo, get moving somewhere where you won’t hear stuff. Finn and I are going to his room.”
“You are?” Beemo said.
“I am?” Finn said. “With you?”
“Yep,” Marceline said firmly.
“Oh… okay…”
As Marceline pushed Finn forward, guiding him to the stairs, he glanced back in total bewilderment at Beemo. The little robot’s eyes had gone wide in realization, giggled just like Princess Bubblegum did whenever someone made one of those dirty jokes that Finn didn’t really understand, and then Beemo saved her game and left for downstairs and into the basement.. or at least a root-level chamber that Finn called the basement.
“Um… Marceline?” Finn asked timidly, twiddling his fingers childishly as Marceline gently but firmly led him up into his room (which felt a bit empty without Jake there). “What are we doing?”
“Well,” Marceline drawled, and Finn thought for a moment that scary though Marceline was, it was nice having her there. He liked having people in the house; it wasn’t so empty anymore, and it felt good like when he was having parties. It was nice having lots of people around with him, especially someone as surprisingly nice as Marceline could be. It was a little bit like hanging out with Jake, but different…
Marceline said something. Finn tuned back in to hear her say, “…So rent has to be paid and stuff, little boy!”
“Wait, what about the rent?”
Marceline snorted. “Pfftt. Don’t you listen? I’m your landlord, Finny-boy! That means what I says goes, and I say, you owe me rent so I let you stay in my house!”
“But you said it was a gift!”
She giggled. “Changed my mind, buddy-boy.”
“Aww!” Finn whimpered, suddenly afraid; they had hardly any treasure left from looting recently… “Um… I, uh, guess you should got to the treasure room and pick out what you want…” He hoped like crazy that Marceline was like a magpie and would just grab stuff that looked pretty.
“Nah.” Her hand went down his shoulder and kept sliding down. On his chubby bicep, on his elbow… now she was leaning down, and then her hand found his, swallowing his hand up in her grip and pulling it up. She smirked and gave his hand a squeeze. Finn giggled, it felt nice. Straightening up, pulling Finn out of stride for a moment, Marceline said loftily. “I have treasure, it’s not that big a deal. The rent I want is a little more…” She looked down at Finn, grinning, and suddenly Finn felt like he was a prime steak she wanted to eat so bad she was going to swallow it whole without even chewing.
“…Carnal,” she said. Marceline looked like she wasn’t quite happy with her choice of words. “That,” she added. “And your buddy Bubblegum tells me she thinks you need some education.”
“Uh, yeah,” Finn said awkwardly. “I think it was, sexual education? Whatever that is.”
“Heh, yeah, you defs need it!” She led him to his bed and sat down, patting it. Finn sat down next to her, wondering what was going on.
Marceline looked around the room, strangely nostalgic. “I used to sleep in this very room,” she said suddenly. “Right where you do!”
“Really?” Finn thought that sounded kind of cool, sleeping in the same spot a sexy lady like Marceline did.
“Yep.” She nodded, and then looked distant. “Things were pretty cool. For…” she faltered. “For a while anyway.” Her hand loosened against his hand, and she sighed.
“What’s the matter?” Finn said.
Marceline looked down at him. She smiled faintly. “…Nothing. Old news. Nothing to worry about.”
He said nothing, but squeezed her hand. Marceline’s eyes widened in surprise, and for a moment, that was it. Then, she squeezed his hand back, smiling, and Finn was struck by how much older she was than him, and how much bigger she was.
Something stirred in the lower part of his belly, a heat pulsing into the thick meat of his thighs. He squirmed about, panting under his breath.
Marceline grinned, and without warning, leaned over and gave him a brief kiss. “You’re a little cutie,” she said simply. “You’re gonna make a great consort for some lucky royal someday.”
He giggled. Being told that, by such a pretty woman, floored him. “Really?!”
“Yeah.” She smirked. “And you know…” she was scooted closer to him, and the sweet swell of her hip brushed against his leg. “Queens are better than princesses.”
She kissed him on the cheek. “Now,” she said. “I’m your landlord. And I’m your sex education teacher, got it?”
“Uh huh,” He said.
“So you’ll do whatever I say, right?”
“…Yes,” he said, a bit wary.
“No matter what.”
“Uh huh!”
“And you won’t ask dumb questions, got it?”
He nodded, licking his lips. “Okay.”
“So, here’s the deal,” she said, leaning over. “The rent I want…”
She kissed him again, and this time her lips found his mouth, hungry and full of need. The whole of his mouth was taken into her lips, and she sucked upon them with something almost violent, and he squealed as she forced him down on his back, her weight settling onto him as she straddled him, her thighs squeezing his knees, and she kissed him long and hard and strong.
“Is your body,” she breathed, and kissed him again, humping against him.
For a moment, Finn almost panicked, but she was just too big. He squirmed but her arms slid under him, and a grinding hump from her hips pinning him to the bed. He struggled, wiggling and bumping up into her, and she growled in approval, kissing him again and harder. He went totally still as the softness of her breasts flattened against him, pressing against his chest and belly, and he stopped, feeling a steady electric pulse that had to be her heartbeat.
“Mmm,” Marceline said as she sat up, flushed and grinning. “You taste yummy.”
Finn squealed as she peeled away, and he was hurting, part of him was getting hard… “Ah, ah! What’s happening, what is-“
“Hush,” she said gently. “All part of the natural sex machine, little buddy.” He blushed at the pet name. “Now…” Her hand moved down, squishing into his soft belly and settling onto his groin. He squealed as her palm slid down his wait and pressed into the bulge of his penis and testicles, giving him a quick and lovingly squeeze. “Lemme see what I got to work with here.”
“Ah, AH!” Finn squealed, squirming around as she shamelessly fondled him through his clothes. “Marceline! Ah! What are- oh, please, don’t stop doing that!”
She grinned. “I’m good, huh?” Her fingers pressed in and her palm squished against his penis, and he felt her through his clothes, and she cooed as he started getting hard under her not-so-tender ministrations, her fingers squashing up on his testicles, spreading and sinking, feeling their heft and roundness.
“Ah, AH!” He cried out, tears leaking at the corners of his eyes, blushing bright in humiliation and fear. His legs pumped, thigh muscled bunching up, and Marceline leaned over to kiss his tears away, her lips soft and inviting, and from sheer impulse Finn kissed her before she pulled too far away. She giggled, mumbling something about ‘eager boys getting the good feels’.
“Just let it happen,” Marceline said soothingly. “Work with it!”
Her hand pressed into his now erect penis, pressing it down a little. It rose back up, and she pushed it down, her hand still on it as it rose again. Again and again, she forced it down and waited for his natural muscle-powered reflexes to force it back up, her hand pumping him up and down and all over again, and Finn was breathing faster and faster, blushing and sweating and whimpering at her every touch, and the lovely boy-sounds he made, quiet and soft and squeaking, was like a chorus to this first sexual experience for him.
And Marceline kept kissing him, still so very hungry but not so violent, she kept leaning down to kiss him and give him brief little licks, soft as rain on grass and even quicker, and she was blushing a little now, giggling at the sound of her lightning-quick smooches.
“Y’know,” she whispered into his ear, a little fevered and shy. “I, I really like you, Finny.” She kissed him again on the ear.
“Marcy,” Finn said, voice hushed.
She went still, eyes wide and blushing bright. “What you call me?”
“I’m sorry!” He squeaked. “I don’t mean-“
“No, no!” She gulped and said. “I… I like it.” She smiled. “Say it again.”
“Marcy?”
“Again!” she commanded, pumping his penis again.
“Marcy,” Finn breathed, now pumping his hips against her hand.
“One more time!” She said, wrist almost blurring as she worked his body.
“Marcy!” Finn cried, eyes shut and mouth open, tongue almost lolling out as he panted needfully.
“One more time!”
“MARCY!” He said, and it almost wasn’t a word, but a senseless squeal, syllables just barely wedged up into a primal declaration of submission and affection.
She let go of him, ignoring his startled whimper. “…Good boy,” she said, and kissed him.
She moved off him, and began sliding her dress off. Finn squealed and averted his eyes, erection almost hurting now. “Take your clothes off,” she said.
“Huh?!”
“Your clothes!” Her dress was a lump on her head now, and there was blue-gray skin, and faded scars, and she was so beautiful it hurt. “Take ‘em off! Now, now, now.”
Finn turned aside hastily, sliding his pajamas off, and the air was cold against his bared shoulders as he struggled out of them, and he’d managed to peel them off down to his waist (his erection complicating matters) before Marceline seized him from behind and pulled them so hard there was a ripping sound. Finn flinched, faint red welts rising up on his waistline and below from where his pajamas had been shredded off. He kicked them off forlornly, a bunch of fuzzy red scraps left no the ground, and he felt so exposed and naked now…
Marceline’s hands found his waistline, sinking into his chubbiness. “Sorry,” she said, and kissed his neck. Finn moaned, a faint fleeting squeak of a sound, and again as she kissed him on the back of the shoulder. She kept kissing him, moving down and down, on his back and on the side of his belly and on the faint bulge right below the small of his back, and then he squealed out loud as her inquisitive lips found one of the welts she had raised, right on the swell of his tender and large buttocks, and she kissed him softly and sweet there.
Her hands seized his sides as she stood straight up, and Finn was hauled over the blankets; he saw a glimpse of blue-gray, and her surprisingly bony knees, and then his bare butt was sitting on something soft and cool, and curly hairs poking right up into his butt and softness all behind him and above him, two heavy but soft weights squashing into the top of his head as Marceline removed his hat and let the enormity of his hair down-
Marceline, having forced Finn onto her lap, squealed as his hair, longer than hers, fell over her front, totally covering her nude body and piling up down her muscular legs. “Your hair is gorgeous!” she squealed, and for a moment, she sounded like the little girl she had been a long time ago. Her hands darted for the golden splendor, and stopped. She gasped, her mouth sounding try. “Can I… can I touch it?”
Finn, dazed from having his hat removed and sitting in the naked lap of the sexiest woman he’d ever met, could only say, “Okay!”
Her hands dug in, and Marceline cooed, bringing a bundle of it to her face and inhaling deeply. “You smell so good,” she sighed, giggling, and let it fall. She humped into his butt, her loins grinding happily into his buttocks and trying their hardest to find their way in, and he squealed at how hot she felt down there, not that he realized what was going on.
He curled up, feeling scared, and then Marceline’s hands slipped down over his belly, hugging him. “I wanna eat you up,” she purred. “I wanna feel you all inside me, squirming around and sliding up and in me forever and ever!”
“Please don’t eat me,” he whimpered, giving voice to his nightmares.
She gasped at the tone of his voice. “Hushies, little boy!” She poked him in the tummy, and then her hand slipped down, finding his penis, which had gone nearly flaccid. “I,” she started, and her hand pumping him down again with each word. “Will,” faster and faster now… “Never,” Quicker now, harder and powerfully, her grip tightening around his flesh. “Hurt,” and her fingers were squirming around the underside of his penis, into the delicate flesh, gentle and strong. “You.” Her hand was sliding in and out as she pumped him, and Finn was squealing and almost crying, but not in pain or discomfort, it felt good-
She let him go and leaned back so she could kiss him on the back of the head. She rolled over on the bed and Finn landed on his side, and he looked up into her face, smiling sweet and tenderly at him. He gasped at how big she looked, and how cute her little fangs were, poking into her lips.
His blankets descended over him, her hand tweaking it up over the both of them. Everything went dark, but he saw her eyes glowing softly in the darkness, and the shine of her grin in the dark.
“C’mere,” she said, and it almost sounded not like an order but a plea.
“Marcy!” He squealed, scooting into her. She grabbed him, and they squeezed onto each other; he cried out and she purred as his erection met the soft flesh of her belly, digging in just under her belly button. “AH! What do I do-“
“You leave that to me, little boy,” she said, sharp but reassuring, and he quieted. Her hand seized his hips, dragging him down, pulling him southwards, towards her crotch…
Soft curly hairs against the tip of his penis, it felt warm there, and Finn felt dizzy at it. Marceline’s hands slid over, grabbing his butt, and she gave him a violent pull as she forced him into her, and her vagina eagerly swallowed up his penis with all due haste, and Finn actually screamed, short and sweetly, as she gave him a welcoming squeeze.
“Ooh, we got us a screamer!” Marceline said, squealing happily.
Finn gasped, “I can’t… Marceline, I… I…”
“Hush,” She said, and hugged him tightly to her body, burying his face into her body. “Let me take care of you.”
“O-okay,” he whimpered as her hip muscles squeezed into him, and he cried out again, like rapturous heat was exploding in his loins, and it felt too good, it just felt so sweet-
Marceline kept grinding and pumping, growling with every movement, her breathing getting faster and harder, her whole body working against him. If he hadn’t been so strong, Finn might have been pulverized by the sheer unimaginable strength of her immortal form (and for days afterward, his delicate hips were laced with faint bruises, but he only grinned when anyone asked about them).
Her body lurched up, teeth bared and her breath panted, and she dropped back onto Finn with renewed vigor. “Come here,” she said, indistinctly and for no apparent reason, caught up in the mood.
Finn moved with her, thrusting and pumping as best he could, trying his hardest to match her rhythm, and she did her best to make it easy for him, swinging herself easily against him and as gently as she could.
For Finn, it was like riding the ocean in a storm, but not an ocean as dark and scary as he was used to, nothing something terrible that would swallow him up and destroy him; this was soft and sweet, beautiful as the dawn and sweet for all its fierceness, and these and other such platitudes ran through his head as he struggled to keep up with her, unknowingly learning from her movements and patterns.
As they moved within each other, Marceline panted out, and in bits and spurts whispered sexual mechanics to him, told him what was precisely going on inside her and what she was doing to him, what the purpose of it all was, how it was working for both of them, what the dangers were, and the other boring stuff like that. As far as an object lesson went, given what she was doing to him, it was pretty memorable.
Heat and motion, friction and emotion.
Finn’s fear of her began drowning under the tide of what she was doing to him, these moments of perfect beauty and rapture.
She thrusted again and again, forcing more of him into her, like she yearned to swallow him up and bring all of him inside her and keep ravishing him within her, like a birth in reverse, and from the sounds of need and satisfaction she was growling, this seemed pretty accurate. Finn squealed, hair slick with sweat and he cried as she pulled him the wrong way too many time, dragging on his hair until his scalp ached, and Marceline whispered, “Sorry, sorry!” and since he was too small for her to kiss him while he was inside her, she lifted up her hips and rested on him, squeezing her thigh muscles sweetly until he cried again in pleasure, the pain forgotten, and with that, she started working him faster and faster, all manner of little tweaks and touches until her little boy-toy was hissing out little proclamations of worship to her glory.
“My Queen!” Finn said, and he was so out of it he blushed and said he didn’t remember it the next day. “Marceline, Marcy-Marcy-Marcy, my QUEEN! Eat me, suck me up, I like you, like you, like you!”
“Heh, hah, yeah!” Marceline laughed, honest and happy for once, without any pretension to being tougher. “Who’s a good boy, Finny is a good boy!” She giggled and squeezed him, hugging him from the inside, and he squealed happily into her, his mouth frantically pressing against her belly (because that was as high as he could go) in sloppy open-mouthed kisses.
He felt so sweet on her, her lovely boy-toy, her human, her Finn.
A sense of loyalty swelling up inside her, she felt Finn squeal one last time as his hips pumped with a power that startled her briefly, and he pumped into her once, twice, and again before he slumped into her. “Hee, you liked it!” She said, kissing her hand and pressing it against his cheek.
Finn only squealed in delight.
Marceline giggled, not even close to orgasm but she decided that Finn would do better after a few more lessons. “Not bad for your first time, kiddo,” she said, hugging him again with her vaginal muscles. “You’re a great student. You may consider the rent paid until next month.”
“You mean,” Finn said, word slow and slurred, clearly on the edge of unconsciousness. “…Next month… again?”
“Sure thing,” she promised.
He grinned under her. “Whee,” he said dazedly, and collapsed against her.
Marceline smiled as he drifted into sleep, and she hummed a song she’d been thinking about writing, and her voice took him into sleep, and as he cuddled her, she looked around this room that had been hers a long time ago.
She smiled. She had a memory to replace older and less kind ones. She hugged Finn – her Finn – with her body again, his penis softening but still happily inside her, and she settled down for sleep too.

When he woke up in the morning, Finn found that Marceline was gone, she’d clothed him while he was asleep, and a note pinned to his bed read ‘COME AND SEE ME BY YOURSELF FOR FOLLOW-UP LESSONS! LOVE, YOUR VAMPIRE QUEEN’.
And later that day, when Finn had been hanging out with Bubblegum, his shorts had dipped too low and she’d giggled, cheerfully giving his butt a pinch and a brief smack before she directed his attention to the big M that Marceline had put on him while he was asleep.
