# Incidental Intimacy

"Marco!" Star yelled as she watched the giant, furry jaws of the monster close around her friend, cutting him off mid-sentence. They had been struggling to hold the huge dog-like beast back for the last few minutes; they had retreated inside but it was still after them, smashing its head and limbs through windows and even the walls. The young princess had been throwing everything she had at it, but none of her spells seemed powerful enough to defeat it. Now her eyes went wide as she watched the monster swallow, sending Marco on his way in a single gulp while she stared on in shock.

The beast roared, exposing his strikingly empty maw, and the sheer force of its breath threw Star against the back wall of the room. Before she had time to recover, she felt the beast’s giant hand wrap around her, and she was yanked, screaming, out through the window. She struggled as she was brought up to the creature’s face, her wand pinned to her side along with her arms. The monster opened its jaws wide.

“No, no no no,” Star muttered as she saw the jagged teeth growing closer. But she was unable to put up any real resistance as the beast quickly threw her into its waiting maw and snapped its jaws shut. Star felt her side grow wet and watched the world go dark as she landed on the beast’s slimy tongue.

“Ugh! Let me out of here you smelly-” The tongue suddenly pressed her against the roof of the creature’s mouth, interrupting her words along with whatever spell she had been getting ready to cast. The princess felt herself pushed towards the back of the monster’s throat. She did her best to struggle, but she was tired from the fight and could barely even get her bearings.

“No! Stop!” she managed. A loud gulp filled her ears- this thing clearly wasn’t going to listen to its food. And just like that she was sent down the beast’s throat- in a single swallow, just like Marco.

Naturally, she fought the whole way down, but with the flesh around her pressing in from all sides there wasn’t much she could do- of course that didn’t stop her from shouting as many Mewnian insults as she could along the way. The princess became thoroughly soaked in monster spit as she was squeezed along, the mucus seeping into her dress and coating her exposed skin.

Suddenly, she felt the darkness open up beneath her and she was gripped by the sensation of falling. She landed quickly with a wet thud on something hard and lumpy.

“Ow! Come on! Haven’t I had enough?!” came a familiar voice, as the form beneath her started to shove and squirm.

“Marco?!” Star called back. She did her best to get off him before holding up her wand and producing a dim light.

Sure enough, there was Marco. The pair sat facing each other, their legs pressed up together as their knees were forced to their chests in the confined space.

“Star?!” Marco called out in surprise, sounding both relieved and concerned.

“Marco!” the princess yelled, reaching over their knees and throwing her arms around him. They were silent for a moment, until Marco spoke again.

“So, it got you too, huh?” he asked rhetorically.

“Yup,” Star replied in a matter-of-fact tone, seeming to have calmed down quite a bit now that she knew her friend was safe. She took a moment to look around their enclosure. They were packed in tight against the slimy red walls of the creature’s belly, with barely enough room between them to breathe, let alone maneuver.

“How are we gonna get out of here?” she asked, now starting to sound a bit worried.

“Can’t you use one of your spells?” Marco asked.

Star pouted and shook her head, “I used just about every spell I have already. Besides, there isn’t exactly much room in here for a narwhal blast. Can you karate us out?” she asked hopefully.

“I can barely even move around, especially now that you’re in here too.”

She knew it had been a silly question, but she was happy he had tried to consider it anyway.

Silence filled the stomach as the duo paused to think. Well, near silence; the slimy walls around them squelched and dripped as they undulated, providing a wet background to their thoughts. After a few moments, the walls suddenly squeezed in on them tightly, pressing them against each other rather forcefully before receding once again.

“Hey, what was that for!? You already beat us!” Star yelled, punching at the slick flesh as best she could.

“It must be starting to digest us,” Marco thought aloud.

“Digest- Oh, no no no no no. Marco, what are we gonna do?” Star asked, getting a bit frantic.

“Calm down, calm down. We’ve gotten out of worse spots than this, we’ll think of something… What about your dimensional scissors?”

“Errrm, I left them by my bed,” she replied.

“What about some kind of teleporting spell?”

“Ugh, those are so hard! I haven’t learned any yet.”

“Um, well what about-” Marco stopped mid-sentence, his eyes caught by something just below face level.

“Marco?” Star asked.

“Um… Star…” the boy replied, pointing towards her chest with one finger of his squished hand. The princess looked down and her blue eyes grew a little wider. A sizable hole was starting to form in the fabric of her dress. The acid- it really was starting to digest them. Star gasped in surprise and looked back up at her friend with a good measure of fear. She found the boy still staring blankly at the hole in her clothing.

“Marco!” she yelled, throwing her arms around her upper body and turning as red as the flesh around them.

“Oh! Um, sorry…” he replied, blushing a bit himself.

Star gasped again. “It’s happening to you too!” she exclaimed, pointing at his arm. A portion of his signature red hoodie had been worn away, exposing the white undershirt beneath.

“Aw, man- we really have to get out of here! Come on, think!” The pair began to rack their brains frantically, trying to come up with a plan, occasionally bouncing ideas off each other but without any luck.

The longer they took, the more each of them began to get distracted by the… revealing nature of the monster’s stomach acid. Marco had tried not to look at first, but the juices had started making easy work of Star’s already battle-worn dress. The entire top half was already almost gone and the bottom was on its way out. Star kept her arms over her chest and tried to hide herself as discreetly as she could, trying to pretend she didn’t notice her friend constantly glancing at her. But in his defense there wasn’t much else around to look at, and Star was noticing some things of her own.

Thanks to his hoodie, Marco’s chest had an extra layer of protection, but his pants were another story. She didn’t think he’d noticed yet, but every so often she snuck a peek and found the holes in the covering growing larger and larger. And now she could swear she saw a bit of white by his crotch.

Minutes passed, with fewer and fewer words being exchanged between them as they ran out of ideas. The stomach contracted around them a few more times; pressing them against one another and producing frustrated grunts and awkward blushes. Before long a sense of hopelessness started to settle over the cramped enclosure.

Marco took as deep a breath as he could of what little air was left and sighed.

“Well, we’re both naked…” he said. He knew it was super awkward, but they hadn’t said anything in a while and he couldn’t stand to just sit in silence anymore- so he might as well just say what they were both thinking. At first Star didn’t reply, and he thought they would return to their silent despair, but then she spoke.

“Marco… are we going to die in here?” They hadn’t been in any pain yet, but she knew that now that their clothes were gone they had no protection left.

“Star…” Marco started to say, but he found himself at a loss for words.

There was another moment of silence as the stomach gurgled around them, but then Star spoke again.

“Marco, there’s something I have to tell you…”

“Yeah?” he asked.

“I… I… I like you, Marco.” She looked him in the eyes. He looked surprised and a bit taken aback, so the princess began to sputter before he had a chance to reply. “I know this is already super awkward and I should have picked a better time to tell you but I was just so… ugh! But now if we’re going to die in here I just had to tell you before it was too late so-”

“Star!” Marco interrupted.

The girl went silent.

“It’s okay… I think… I think I like you too…” Though his words seemed unsure, his expression showed otherwise. The two stared at each other, blushing in the dim light. “I’m glad you were my friend, Star,” Marco said, a deeper meaning evident behind the simple words.

“Marco…” Star took a long pause, seeming uncharacteristically timid, “There is one more thing…”

Marco looked at the princess questioningly.

“Since we’re going to die in here anyway… could I… see your…” The girl blushed even more deeply and averted her gaze, downward towards his legs. It took Marco a moment to understand.

“Oh!… um… sure, why not…” He took a similarly long pause, “Could I maybe… um…”

Star nodded quickly, apparently too overwhelmed to talk.

Given their mutual feelings, and having lived together for the time that they had, they were both guilty of having wondered what the other looked like underneath their usual apparel. Neither of them had seen a member of the opposite sex naked before, but they each had some idea of what to expect… And it was hard to blame them; they were at that age where thoughts like that were all too prevalent. So now that all the cards were on the table, it only seemed natural to share this one last thing before the end.

“So, um, on three?” Marco offered.

“Right,” Star answered.

“One, two… three.” Together, the two spread their legs, squishing their bare knees into the stomach walls, revealing themselves to one another.

Star’s eyes lit up as she took in the sight. The turn of conversation had apparently made Marco do more than blush- in fact he was so hard it was a wonder he had been able to keep himself hidden as long as he did, though to be honest it was something he had gotten used to doing around Star. The swollen member bobbed and swayed as the stomach continued to ripple around them, the boy’s testicles hanging loosely from its base, nearly touching the wet flesh below.

Marco’s jaw dropped just slightly as he took his first look. Star’s private slit now showed between her legs, the bottom of which was gently pressing against the slimy muscle below. It was no wonder she had been so distracted by the topic, with the stomach floor practically pleasuring her as she was forced up against her crush. Short, neatly groomed hair surrounded the damp lips, matching the color of the long hair that flowed from her head. And just above the top of her opening sat a little red heart, just like the ones on her cheeks.

They stared at each other for a long moment, exactly how long neither of them could say. Then, ever so slowly, Star began to reach out her hand. She gave Marco plenty of time to stop her, but he let her reach, perhaps still too mesmerized to act. Gently as could be, she extended her hand, and touched the tip of her friend’s member. It jerked as the muscles contracted involuntarily. Marco let out a tiny grunt, the sensation pulling him back to reality, but still he didn’t stop her. He watched as she grabbed his penis lightly with the tips of her wet fingers. It pulsed a few more times at the sensation. Very gently, Star began to slide her fingers up and down along its length.

“Um… Star?” Marco interjected lightly, now starting to feel a bit awkward again. The princess took her eyes off his erection and looked up at him. He kind of expected her to recoil and apologize, but instead she simply said,

“Well… what are you waiting for?”

Marco got the message, and it became clear to him that she had meant for them to cross more boundaries than simply looking at each other. Under normal circumstances he probably would have stopped this right then and there (heck, he would have stopped it a long time ago), but trapped in the stomach of that beast, secluded from the rest of the world and facing the end… everything just felt okay.

Marco reached out a hand of his own, seeing no resistance in Star’s face as she returned her attention to his privates. He started by placing a single finger on her little heart. Her whole body shuttered at the touch, a motion that he could feel travel down her arm and into his erection. He let his finger slide down and trace gently over her slit, feeling the gentle, wet hairs as he went.

Star’s pleasuring was getting to him now, and he started to feel a bit more ambitious. He pressed against her lower lips lightly with his thumb and forefinger, and eased her entrance open. The newly exposed flesh shone an entirely different, far more vibrant shade of red than the stomach walls around them, and it seemed even more slick. Marco let his fingers slip into her folds and Star began to moan.

“Ooohhh-ho-ho-ho Marco, that feels great…”

They continued to pleasure each other, exploring the mysteries of this new dimension of experience that had been opened to them. Then, suddenly, the stomach around them contracted once again; determined to knead its contents into mush, but the actual result was something completely different.

The two of them yelled as they were suddenly squished together. Their chests pressed up against each other, as did their spread legs. Having nowhere else to go, Marco’s member naturally found its way into the only place available. They both gasped (Star much more loudly) as the walls around them relaxed once again and they fully realized what had happened. They both looked down.

A majority of Marco’s penis was now inside Star. She could feel him pressed up against her insides, and he could feel her walls pulsing around him as they became accustomed to his presence. He tensed reflexively at the sensation, and he felt her squeeze reflexively in response.

“Star- I- I’m so sorry, I didn’t mean to-” Marco was cut off abruptly.

Star was gazing at him intently, a surprisingly innocent smile on her face. She seemed remarkably relaxed, but it wasn’t her expression that had shut him up. She had moved forward, pushing him the rest of the way inside.

The boy was speechless; totally, utterly speechless. He had his erect penis completely inside the princess of Mewni; Star Butterfly; his best friend… Her actions seemed unmistakable, but he still felt too surprised to make up his mind as to what to do next. Luckily, the young princess knew exactly what she wanted to have happen; whether she had intended this at the beginning or not, she knew how she wanted things to go now.

Slowly, Star started pumping her hips. Back and forth, back and forth, her bare rear sliding along the slippery stomach muscle below. Marco looked into her eyes, she definitely seemed sure of herself. So he nodded slightly, and let himself fall into the sensation.

As he felt her walls slide over him, caressing his member, he started to move his own hips in time, adding to her motion. Their bodies began to synchronize, their privates beginning to contract in unison as Star’s vagina coaxed Marco’s penis ever deeper and deeper. Their pace grew faster, the shared pleasure washing away any restraints either of them had left.

“Star!” Marco exclaimed.

“I know Marco, we’re so close!” she replied between labored breaths.

The hearts on Star’s cheeks and crotch began to glow, shining a white light onto the stomach around them. It grew brighter and brighter as the two of them neared their peaks.

Finally, they both cried out in pleasure as a final, fierce series of contractions erupted from their joined skin. As the light radiating from the Mewman girl became blinding, they both closed their eyes and they were each met with a brief flash of a blood-red moon.

The next thing Marco knew, he felt himself laying splayed out on his back against a hard floor. He opened his eyes and as they adjusted he began to make out the inside of Star’s bedroom. He felt something warm between his fingers and looked to his side. Star was lying next to him, clutching his hand, spread out on the floor, same as him. She looked to him. They were both still naked, still panting, still a bit wet, but somehow they were back home.

“Star…” Marco started breathlessly, “What just happened? Did you save us?”

“Woah… I’ve never cast a spell like that before!” she said excitedly. The two of them sat up and looked at each other, and after a moment they both started to laugh. Whether from relief or disbelief it was hard to say.

When they stopped, Marco got to his feet and offered Star a hand to help her up. They looked at each other for another moment, taking in the sight of each other’s bodies in the full light of the room.

“Well, I guess we should put some new clothes on… I’ll… I’ll let you get dressed,” Marco said, blushing despite everything that had just happened. Star released his hand as he turned and headed for the door, smiling as he went. He had a lot to think about.

Of course, what I can’t stop thinking about are the little coincidences: like how the stomach seemed to contract at just the right moments, or how the acid managed to dissolve all their clothes without leaving a scratch on either of them.

Star did seem very sure about the whole thing…

That forbidden chapter in the book of spells couldn’t have played any part, could it?
