"Darling? What do you think would happen if I made pancakes with Mountain Dew instead of water?"

I paused, my pen hovering over the page in the middle of summarizing my findings for a lab I'd been working on at my university. I didn't turn around to face my boyfriend, Kol Mikaelson, who stood behind me in the kitchen, instead just staring off in thought for a moment.

"I don't know," I said, finally turning around to look at Kol. "As far as I'm aware, water's not one of the things like baking soda or eggs that's insanely important to the chemistry of baking. As long as you have the same amount of liquid, it should be fine. Maybe a little sweeter than normal, but basically still a pancake."

Kol grinned. "Excellent."

"What exactly brought this on?" I asked, standing from the kitchen table in the Mikaelson compound where I'd been working and wandering towards my boyfriend. "Just out of curiosity."

"Well you see," he said, holding his hands out in a grand presentation gesture and fixing me with a giant grin. "While I was getting the ingredients for making pancakes, I also found Mountain Dew. The rest is history."

"Interesting..."

I trailed off as I finally reached Kol, stopping so I could hold onto his arm and lean around him to look at the ingredients laid out on the counter, Mountain Dew included. My eyes wandered back to my books, still open and waiting for me on the table. I had no desire to go near them again right now, and this was the absolute perfect distraction. I looked back up at the grinning face of my boyfriend.

"Do you need any help?"

Within half an hour, Kol and I's initial experiment had expanded to encompass the entire kitchen and just about every ingredient we had in it. The Mountain Dew pancakes hadn't been much different than the regular pancakes, so we'd gotten progressively more creative in our ingredient substations, snacking on our successes as we went. My books lay long-forgotten on the table, Kol enabling my chaotic science tendencies in the best way possible.

"What if we put pop rocks in it?" asked Kol as he riffled through a drawer of sweet treats in one corner of the kitchen. I hummed to myself as I mixed our latest version, with orange juice instead of water.

"I don't know," I said. "I think we'll just get little pieces of candy in it without the pop, since the liquid in the batter would probably dissolve the candies enough to trigger the reaction before anything else. We won't know for sure unless we test it, though."

I finished stirring, then wandered over to join Kol. He'd set the pop rocks on the table along with a few other types of candies, and now stood in the open door of the fridge. I rested my head on his arm and hummed thoughtfully, until my eyes landed on something else interesting in the fridge.

"Since you've been back in the modern world... has anyone introduced you to the marvel of Coke and Mentos?"

Kol turned to face me, eyebrows furrowed but a smile on his face.

"No love, I can't say they have."

I grinned. "Then I can't wait to be the one to show you."

I snatched the bottle of Coke out of the fridge, snagging the Mentos and a piece of paper with tape too before plopping them both down on the table where we'd been mixing our batter. Excitedly, Kol joined me, wrapping his arms around my waist and resting his chin on my shoulder.

"Okay, so first we need to make the tube to hold the Mentos,  to make sure they all drop in at the same time when we want them to," I explained while I worked. I rolled the paper into a tube, covering one end with my thumb and then holding it out for Kol. "Put seven Mentos in there, please."

He complied, sneaking one for himself and then passing one to me. I looked over my shoulder at him, smiling, and he leaned in to give me a soft kiss.

"What's next, darling?" he asked, his voice low. I leaned back into him a little more, but returned my attention to the Mentos.

"Now, it's time for the reaction. Unscrew the lid of the soda, please." Kol took care of it, shifting a little behind me in anticipation. "Good. Now, I'm gonna dump these in, and after I do we're gonna step all the way back, okay?"

"Okay. And what happens after that?"

I shot him a grin over my shoulder. "Science."

With that, I put the tube of Mentos to the neck of the bottle, then quickly moved my thumb and let them drop all at once into the soda.

Kol's grip tightened on my waist as he used his vampire speed to get me to the far edge of the kitchen, hopefully out of the splash zone. A moment later, the reaction started, and the soda quickly bubbled and fizzed until it became a geyser, exploding out of the bottle. Kol gasped from behind me as it hit the ceiling, and I smiled.

The reaction didn't last very long, but once it fizzled down, it took Kol a minute to let me go and move to meet my eyes. He had a ridiculous grin on his face that I quickly mirrored.

"That was amazing, darling," he said. I practically glowed at the compliment.

"Thanks! It's really cool how it all works, actually. See, carbonated beverages are full of dissolved carbon dioxide gas, which wants to form bubbles and escape the pressure of the liquid. But to do that, it has to break its bonds with the water and interact with itself. Because the Mentos candies are actually covered in a bunch of tiny grooves, it makes it easier for the bonds between the carbon dioxide and the water to break, making the reaction of bubbles escaping the soda happen at a much, much faster rate!"

I'd started pacing a little, gesturing with my hands as I explained, but froze when I realized I'd been rambling for more than a little. I turned back to Kol with a grimace.

"Sorry. I know you probably don't care about how it works-"

"What? No! That was excellent, the way you explained everything!" He grabbed my hands in his as he pointedly met my eyes. "Darling, you're the smartest person I know. And it's absolutely incredible. Please don't ever apologize for the way your eyes light up and your voice gets all excited when you talk about something you love. It's one of my favorite things in the world to see."

I started tearing up a little bit at Kol's words, and as soon as he finished speaking I wrapped my arms around his neck and pulled him to me, kissing him, hard. He smiled into the kiss and wasted no time wrapping his arms around my waist and pulling me tighter to him. Finally, after a few long moments, I pulled gently away.

"As much fun as I'm having... I do need to finish the lab writeup for my actual science class."

Kol sighed and ran a hand through his hair, then fixed me with a devilish grin.

"Fine. As long as you promise to let me know anytime you have an experiment to do that I can sit in on."

I beamed back at him. "I promise."

Kol gave me a sweet smile, then leaned in and kissed me one last time. Despite the homework hovering in the other corner of the kitchen, I could feel Kol sucking me in and distracting me to the point that I didn't care about my work. I was just about to give in, too, when someone coughed loudly from behind us.

Kol and I turned around to find Elijah standing in the kitchen doorway, his eyes scanning the disaster zone the kitchen had turned into. Soda still dripped from the ceiling, and horrifying pancake mutations were spread on almost every surface.

Elijah sighed heavily, his exhausted stare turning back to me and Kol.

"I trust that this will all be cleaned up before the two of you run off to other activities? Preferably sooner than later?" he deadpanned. Kol scoffed, and I tried and failed to fight a guilty grin.

"Yes, Elijah. We'll take care of it," I said. He nodded once, pausing to stare at everything for an extra moment before shaking his head.

"Good."

With that, he turned and walked out of the kitchen. Even without vampire hearing, I heard his heavy, long-suffering sigh from the other room. I turned to Kol and giggled.

"Oops."

"He loves it," Kol said confidently, waving me off. "We keep his life interesting."

"Well, that second part is definitely true. Come on, let's clean up at least a little bit of the mess. We need to do it at some point anyway, and I really do need to go back to my homework."

Kol booed and rolled his eyes, but moved to start helping me deal with the mess anyway. He picked up the now mostly-empty bottle of soda and held it thoughtfully, then turned to me with a glimmer in his eye that I loved.

"You know darling, if we pointed these in a specific direction for the reaction... we could probably shoot the soda at Elijah and the rest of my siblings."

I grinned. "We absolutely could do that."

We stared at each other for a few beats, nodding slowly, communicating without words.

"I'll superspeed cleanup," Kol finally said. I nodded.

"I'll finish my lab writeup as fast as possible."

"And I'll go get more soda and Mentos while you do."

I high-fived Kol as I crossed the room to retake my seat at the kitchen table and he turned into a vampire-tornado of cleaning. We had evil masterplans to enact, after all, and with the two of us working like a well-oiled machine, the rest of Kol's family and anyone else in this house didn't stand a chance.

SCIENCE!!! Grub for Shon2 [Attack #33]

[totally-a-different-person]

Maybe a Laurel x Eduardo x Jon smut??? Or maybe just laurel x Eduardo/Eduardo x Jon?

Very fun concept I absolutely adore them, and I know this is the sex place where we talk about sex but on the other hand just between the three of them the everyday dynamic in this world is probably so funny anyway (nsft and lighthearted degrading past this point proceed at your own risk)

Laurel was pretty much pushing Jon through the door, Edu shut it behind them as they came in. All three of them were drunk, mostly Laurel, and they were finally getting home. The woman was very giggly and touchy, very literally all over the other two on the way home. Jon squeaked when he was pushed down against the bed, and Laurel attempted to pretty much just tear his pants off but was, much to her annoyance, interrupted by Eduardo who had gotten behind Jon and picked him up by his sides to have him sit up on the bed.

He started placing surprisingly rough kisses on the blond's neck and collar, nipping and letting his teeth graze the soft flesh as he unbuttoned the blue shirt. Jon seemed to be very much enjoying himself so far, helping Eduardo slip his shirt off and tilting his head for him, giving soft breathy moans.

Instead Laurel got onto the bed in front of their sub on her knees and kissed him, catching by surprise as she dragged her fingernails down his sides to his jeans. He gave a sharp moan into the kiss, blushing deeper as she quickly unbuckled his pants, pulling them down.

She gently slipped the waistline of his boxers down, gently taking his cock into her hand and stroking him until she felt him fully hard in her hand, Jon struggling to kiss back as he whined and moaned. Soon the connection was broken anyway, Laurel looking at Eduardo "get the lube, I wanna hurry" she was incredibly impatient, having a bit of a hard time getting her own sparkly belt off with only one hand, not wanting to give up Jon's precious little noises.

Soon she got it off, only then letting go of Jon's cock, the organ twitching slightly at the change. Laurel unbuttoned her jeans, looking down for a moment before back to her lover, gently biting her soft lip and giving him a look that sent shivers down his spine, blushing a little deeper and giving a tiny smile back.

He felt a large hand grab his leg and have him spread them, looking down and leaning into Eduardo a bit more who smooched his cheek before getting up and having him lay back. Edu moved Laurel and got between their sub's legs over the edge of the bed so he was standing up.

Jon always did look so pretty under him, he really thought so. He grabbed the lube he had just gotten and squirted some onto his fingers. The brunette felt a little smirk tug at his lips as he saw how excited Jon looked, staring at his fingers while spreading his legs a bit more as if it was an invitation.

He gently took his hip with one hand, the one with the lube coming down to carefully tease his cute little hole, Jon tensing up in anticipation. Edu chuckled softly and leaned down to kiss his cheek, whispering "look at you, so desperate, we've barely started" he laughed, raspy voice making Jon shover as he blushed deep crimson.

He pushed his fingers in deep, the blond gasping and flinching a bit just making Eduardo snicker more. "Little whore~" he purred, free hand smacking Jon's ass, not incredibly hard or anything, but enough to make him practically jump out of his skin "AH!~" his voice cracked.

Eduardo added a third finger, fingering Jon harshly as he stretched him out, the shorter drooling slightly. Laurel watched, biting her lip hard and rocking her hips into her hand as she touched herself, panting softly. She had taken her jeans completely off, leaving her in just her black underwear and dark purple t shirt that complimented her form wonderfully, being kind of tight fitting.

Edu pulled his fingers out very suddenly and Jon flinched slightly, giving a little gasp and sitting up some, seeming very excited as he watched the older man lubing up his cock. He bit his lip slightly and attempted to sit up but was nearly immediately pushed right back down, Laurel putting her hands on her chest and grinning down at him.

Eduardo waited for a moment as she positioned her thighs on either side of the blond's head, using one hand to gently spread her folds as she spoke "open up, sweetheart" she spoke very sweetly, but Jon knew from past experience with her that didn't mean it wasn't a command. His cheeks burned bright red as he opened his mouth for her.

She carefully sat on Jon's face, biting her lip to stifle a quiet groan when he started tenderly licking, mostly focusing on her clit as he did. Though he struggled slightly to continue as he felt Eduardo pushing inside of him, almost putting the whole thing in as Jon shook and twitched, giving little high pitched moans against Laurel.

The woman gave a soft moan, laughter laced into it as she rolled her hips slightly, holding Jon's sides "Fuck... Just like that... You love that, don't you?" She smirked widely as he leaned back a bit to look at his face, her hand coming back as well to move the hair out of his face, gripping and hugging a bit as she ran her fingers into it to hear him moan again, cheeks a deep pink as he nodded.

"Just a pretty little slut~" Eduardo spat, spanking him again as he started thrusting, starting out hard and fast. That forced a very sweet, muffled moan that tore from Jon's throat, pre spilling onto his stomach from his own weeping cock as he was smacked. The blond couldn't help how vocal he was the room filled with his sounds of bliss, but that didn't stop him from continuing to service Laurel, licking as sucking as she rolled her hips.

She was absolutely adoring this, getting to watch Jon fall apart. She was standing just on the edge of orgasm, biting her lip hard as she grinned, sometimes closing her eyes as well. The girl could see Jon's dick as it twitched desperately while he was fucked, and awed softly as she sort of giggled. "Oh, baby~" She coed, gently taking and stroking it, listening to how her lover keened "You want me to take care of this for you?~"

Jon nodded quickly, Eduardo gripping his hips tighter and tugging him a bit closer as he thrusted. Lau leaned down to press a few gentle kisses along his shaft before one at the tip, feeling it throb slightly in her hand. She took it into her mouth easily, making sure not to get in the way of Eduardo's thrusting as she bobbed her head.

Said man pushed especially deep, listening to the way the shorter cried out. Laurel gave a sharp moan as she finally hit orgasm, grinding down on Jon's tongue as her throat vibrated around him making him whine sweetly. It was only a matter of seconds before he came as well from all of the attention he was receiving, arching his back and moaning louder. THe girl was more than happy to swallow as she rode out her own climax, giving a soft content hum before pulling off and quickly off of Jon's face as well.

Now unmuffled, Jon was nearly screaming as he was pounded, spreading his legs more and whining. Laurel gave a soft sigh as she stared at him before taking her shirt off and getting her bra off as well, tossing them both aside. "Eddie, you've got condoms yeah?" She asked, her usually sweet tone only slightly wavered, clearly wanting to be fast about this. THough Eduardo seemed incredibly focused on the tight heat squeezing around his thick cock, holding Jon's hips tight and listening to him whining and moaning.

"Yeah, t... top drawer" He mumbled under his breath with a little nod and didn't even look at her. He was getting close and felt like he desperately needed to pump his seed into blond beneath him.

Laurel nodded and leaned back to open it up, smiling when she found one and giving a triumphant sort of "Ha!" Shutting the drawer behind herself.

She tore the packaging open and had Eduardo lean back a bit so she could roll it over Jon's dick, the boy's eyes widening a bit as he realized what she was doing and quickly stilled completely, clearly kind of excited. Using her hands to guide it inside of her she lined it up with her entrance and slowly sank down on it, a little moan managing to slip past her lips as she did.

Eduardo couldn't bring himself to completely stop, but slowed down a good bit to make it a little easier. He quickly picked up the pace though once she started moving, and Laurel tried to have the same rhythm as him while she bounced but that was actually pretty difficult and she couldn't totally keep up.

Regardless Jon was practically in heaven, screaming and moaning his lover's names, begging them not to stop and trying to buck his own hips occasionally. He was harshly grabbed by the hips and held still as Edu came deep inside of him, huffing and losing his pace slightly. He buried his face in Laurel's neck as he panted, the girl bringing a hand back to rub the back of his head as she leaned into him.

"You love that, don'cha baby?~" she smirked as she looked down at Jon, still moving her hips "When Eddie fills you like that, I can tell you do" she laughed, it was bubbly but very harsh and blunt, ending with a moan being caught in her throat. One of Eduardo's hands had come to rub her clit while she rode and he started to pick up the pace again, and she seemed overjoyed. "Y... You just love when he shows you who you belong to, filthy little whore~"

There was no warning when Jon came, again, he simply couldn't help himself anymore, it was too fantastic. He arched his back as he filled the condom, throwing his head back and moaning out for Laurel, who just smirked wider and stopped bouncing. As she carefully got up Eduardo pulled out, he also got the condom off Jon and tossed it in the trash. The sub just laid there panting softly and looking at the ceiling, clearly trying to recollect himself.

He was a little surprised when Laurel hugged him but laughed as he was squeezed tight, smiling and wrapping his arms around her as well. "You did so amazing Jon" she spoke pretty softly and gave him a kiss on the forehead as he blushed and smiled more. They were both grabbed and pulled to lay where the pillows actually were by Eduardo, who also covered them all up and wrapped his arms around, the two happily snuggling up with him.

The woman gently ran her fingers through Jon's hair, and gave him a few more kisses, asking if he was ok to go to sleep. Even in her drunken and exhausted state, it was baked into her that at least a little aftercare was definitely necessary. Jon appreciated it, but said he was more tired than anything and just wanted to go to bed, so that's what they did.
