Dark feels chills crawl through her skin as she takes her clothes off, leaving her only with only her underwear. It’s expected for Yellow to keep her laboratory cool, but damn if that was the case maybe they should’ve done this in her room. Dark is freezing. Though, she gets why she chose this place, since it’s below the house and the others are sleeping.
But it’s even worse when she gets on the procedure chair. Shit, that was cold too.
“Ugh, could you turn the air down a little? It’s freezing here,” Dark complains quietly.
“Deal with it,” Yellow says as she walks towards Dark with several tools in hand, “Cold laboratories are safer.” She then begins to touch the skin of her torso, searching for the screws hidden within. Soon, she began to loosen the screws of her chest plate. She listened as Dark’s breath hitched when she opened her up, revealing the complex structure of wires and parts that were to mimic human organs. “Does anything hurt? I could put you to sleep if you want,”
“I don’t give a shit,” Dark shrugged.
“Is that a yes or a no,” Yellow looked at her.
“It’s up to you. You’re the one studying me,”
“Okay then,” Yellow felt her heart begin to race as her gaze flickered down back to the open chest cavity. Without looking turning away, she scrambled for her notebook and pencil, writing down all the details she could see without having to touch anything: Wires are kept organized and even, some are transparent tubes filled with what Yellow knows is to be the Virabot goo she was rebuilt from. Some of those tubes were connected to her lungs, in which they rose and fell at a decent pace. Everything was so fascinatingly human until it came to the heart.
Yellow’s wide eyes scanned the thing. It had both wires and tubes attached to it, both of which were incredibly small it almost gave her chills just to look as it moved when her heart pumped. Every tube was more visible with each beat, her virabot blood illuminating the area against the metal of her heart.
“Is this really that interesting?” Dark spoke. Until then, Yellow hadn’t notice how close she had leaned in just to look at her heart. She moved away just a little bit to look at the rest of the insides.
“Yes,” She said, “It is. Isn’t this fascinating to you too? I mean— look at all of this,” Her voice fell down to a whisper as she brought a hand to slide against her heart. The touch making Dark flinch, the new sensation keeping her quiet temporarily.
“I mean, I’m used to seeing myself like this. So, not really,” Dark shrugged. Though, she had to admit that having her bare heart touched was a new feeling. It was weird, but not unpleasant.
Yellow, with excitement looked at her, “Can I touch your wires? Please let me touch your wires.”
“You’ve already touched my heart, do whatever you want,” Before Dark could even finish her sentence, Yellow’s fingers were already inside of her, urging to get themselves wrapped around Dark’s wires.
She first tugged at the ones attached to her lungs, listening as Dark’s breathing shifted. Curious, she pulled again a little harder and Dark’s oxygen seemed to be knocked out of her by her reaction. After her wires were free, she breathed heavily. Yellow watched as her lungs moved faster, trying to intake as much air as it could, her heart beginning to pound right in front of her eyes.
All of this was so intriguing, but somehow, she just wasn’t close enough.
Without thinking it through, Yellow climbed onto the chair, straddling Dark’s legs. Perfect, she could see better from this angle if not even more details. Without looking, she brought the light above them closer, illuminating more of the open chest cavity, the wires almost seemed to glow below her.
But then, Dark just had to open her mouth, “This is a little intimate, don’t you think?”
Yellow rolled her eyes annoyedly, “This is for research Dark,”
“Uh-huh. And being on top of me is for research too,” Dark mocked.
Yellow almost, Almost considered taping her mouth. Her input was not doing anything helpful, but her verbal reactions certainly are, so she decided to keep her as she is and at least have enough patience to endure her.
With a deep breath, she put her attention back to the complexity of wires in front of her. She then took her notebook and pen, placing them close to her as her other hand reached for the wires deep inside, careful not to unplug any of them.
Even with her fingers just sliding through, she heard Dark’s breathing quickened. That was surely interesting considering she hadn’t even pulled anything. But it did make her wonder what would happen if she did.
Without any further thought, she brought a wire to wrap around her finger and pulled lightly.
“Mh!—” A small moan was knocked out of Dark, her body squirmed for just a moment.
Yellow stared at her for a moment in silence wide eyed. “Was that reaction good or bad?”
“G-good.” Dark nodded, taking a deep breath, “Just be careful,”
“Careful?” The moment that word registered in her head, Yellow did the complete opposite. She yanked the wire, her eyes observing as Dark’s jaw dropped to let out a gasp, her head jerking back.
That was interesting. Very interesting to watch.
When Dark tensed down, she looked at Yellow and couldn’t help but smile, “Just for research purposes huh?”
Yellow only remained quiet but honestly, Dark was starting to irritate her. Even more with the way she even began to twirl with her hair, she squashed down the fluttery feeling in her stomach to favor the annoyance that rose in her, “Don’t touch me,” She said.
“Hmmm, but I’m doing this for research purposes,” Dark mocked, giggling.
Yellow rolled her eyes and pushed her hand away, picking up her notebook, “Such a shame you’re not dead…” She muttered.
“All bark no bite, I hear you complaining but you’re not doing shit—”
Right as she was about to finish her sentence, it rolled into a loud moan as she felt Yellow yank at her wires again, so much harder she even got a tinge of pain, she was almost scared the girl would plug them off.
“My resistance does not mean inability. You wouldn’t want me taking action,” Yellow stated seriously.
Dark gulped, her breathing shaky as Yellow was still holding onto her wires. Her visibly irritated expression despite the small blush across her face almost made her want to push her buttons further. The girl’s reactions were almost entertaining despite the fear she felt, knowing that Yellow is capable. “Okay…Sorry.” She said quietly, nodding.
Yellow finally let go of her, “Now be quiet, somebody might’ve heard you upstairs.” She then turned her gaze back to her notebook, adding more details to the information she’d gained just from holding onto her wires.
At last, she placed her notebook down and gazed at Dark, who still had her eyes on her. Yellow stared for a moment in silence, taking in the sight of her, the visible affect her actions have had on Dark. The girl below her was blushing deeply and cursors she looked…weak. Yellow never thought she’d make The Dark Lord herself look this way. It made her feel powerful.
And she brought her fingers to brush at her surfaces. Her lungs, her heart all the way down to the rest of the wires in which she noticed they began to feel warm. Below her, she noticed Dark just barely squirming, her face contorted lightly. But as her hand reached the bottom, Dark suddenly flinched.
Yellow looked down to see what she had just touched: A set of wires near her pelvic area. Pull them she first thought. But she resisted, figuring that Dark would become too loud.
But oh, she would be loud. Yellow froze in place, fantasizing about the sounds she could elicit out of a much more powerful being just by the pull of a wire. And what if nobody was home with them? She would be shameless, vulgar, maybe she’d scream Yellow’s name begging for her to touch her more, maybe she’d continue being bratty, forcing Yellow to be rough, and maybe then she’d cry and plea for her to slow down.
Suddenly, a forced cough snapped her out of her trance. Thankfully so because what the fuck.
Yellow then looked up, “Huh?”
Dark raised an eyebrow, “Continue your ‘research’?”
Yellow blinked, “Oh, y-yea,” She then picked up her notebook and began writing. Touching the wires around her pelvis gives her pleasure, okay. Okay.
“You seem a bit…distracted,” Dark spoke with a smile, her hand beginning to crawl onto the girl’s thigh, “What’s on your mind?”
Yellow furrowed her eyebrows, trying to ignore the fluttering in her stomach upon the touch, “Don’t touch me,”
Dark’s hand begins to caress her thigh, “Or what? You’ll pull my wires? Ooohh, I’m soo scared!”
Yellow was about to lose her shit. She took her tank off and grabbed both of Dark’s wrists, wrapping them so tightly above her head she was sure it would leave marks. Dark’s eyes widen, her mouth opening to comment about the fact that Yellow was bare in front of her. But instead, she got cut off by two of her fingers being shoved inside her mouth. Dark gagged, humming protests around her fingers, her wrists moving around the fabric.
And then, Yellow picked a few wires from her pelvic area and pulled harshly. Dark’s eyes widened, she moaned loudly, the sound muffled against her fingers.
And then she pulled again, her movements harsh and constant. Dark’s eyes rolled back, her back arching into her, hands moving and begging to be freed. Yellow couldn’t help but giggle at the sight, “Mhm, what are you gonna do about it now?”
It was too much too soon. Dark was almost hurting. She moaned and whined against her fingers, trying to tell her to slow down, be gentle. She murmured the words, though muffled.
Gladly, Yellow caught on, “What’s that?” She pulled her fingers out, now moist with spit.
Dark whined, “Slow— please, please be gentle—”
Yellow stared at her, smiling. Her movements only becoming rougher, in which Dark moaned more, her legs shakily moving up to meet with Yellow’s core, the contact only fueling her. But then, she let go, watching as the wires slammed against her. Dark let out a final yelp before finally breathing heavily, catching her breath.
Yellow on the other hand only watched the state Dark was reduced to. The thing she managed to do to Dark. The girl below her was sweating, her eyes unfocused and not a single mock coming out of her mouth. Yellow only wondered what going further would do to her.
Should she go further than this?
…For research purposes.
Yellow grabbed one of the wires again, rubbing her fingers against it and slowly wrapping it around her a few times. She watched as Dark reacted, the girl letting out a small, shaky moan. After a few moments, she brought her other hands to her underwear, her fingers resting on her clothed folds.
“Are you okay with me touching here?” Yellow asked quietly.
“I don’t give a shit…” Dark murmured.
“Is that a yes or a no—”
“Yes.”
Yellow whispered a small “okay” before pulling her underwear aside, her fingers beginning to caress the warm surface as her other hand twirled at her wires.
Dark whimpered in return, “Fuck...” Her eyes fluttered close, lost in the haze of pleasure. Yellow could not get enough of the sight.
Slowly, she inserted her fingers, curling them around Dark’s insides. “So wet…” She whispered.
“No shit, I wonder why.” Dark opened her eyes, looking at her.
Yellow rolled her eyes. Even reduced to such weakened state, Dark was still an asshole. She reconsidered taping her mouth again, but she was having too much fun for that. Instead, she yanked at her wires again, eliciting a whine and a clench around her fingers.
She had to admit, doing that every time she misspoke was fun, seeing the way she’d double down so quickly. The way her heart would pump quicker, the way her wires would feel warmer, it was all getting to her head. And she still wanted more.
“Having fun I see, is this still for research purposes?” Dark spoke again.
Yellow almost fought back until she processed the position she was in. Oh cursors, just what is she doing? She was supposed to be studying Dark not…whatever this is! She wasn’t supposed to be touching her like this, no— Dark wasn’t even supposed to be in the house right now just what is her problem?!
“I—” Yellow pulled her fingers out, “We’re not supposed to be doing this, you need to go—”
“Hey, hey.” As Yellow was about to get off her, Dark wrapped her tied arms around her neck and pulled her close, “We’ve already come so close, why leave it at that?” She said quietly, tilting her head.
Yellow gulped, trying not to pay too much attention at how close their faces were. “Well, the others—”
“They don’t need to know,” Dark pulled her closer as she smiled, “Your research’s important, isn’t it?”
Yellow remained silent for a moment. If the others upstairs found out at what she was doing they’d…maybe they’d understand. Maybe it wouldn’t be too bad if they hide well enough. But what if they don’t understand? Her friends are everything to her! But if they’re quiet enough…
At last, Yellow sighed, “You’re insufferable,” She said before swooping in for a kiss, her hand wrapping around the wires again, only lightly pulling at them.
Dark kissed back with a small moan, pleased at the pull of her wires. She raised her thigh to rub against Yellow’s core, hoping to return the favor. The effect is immediate, as Yellow’s hips jerked, beginning to grind against her thigh, letting out quiet whimpers.
Their kiss became messy, Dark licked at her lips for an entrance, and within the next seconds their tongues were gliding against each other. Yellow’s mind became mush as she felt her mouth on Dark’s, her grinding becoming slippery. She didn’t know what she was doing with the wires, but whatever she may have been doing, it seemed to have pleasured Dark as her breaths and moans became shaky.
Yellow pulled away, letting out heavy breaths as she rested her head Dark’s shoulder and brought her other hand to rub her clit.
Dark gasped, her body flinching at the shocking pleasure of the mixed movements. Yellow’s finger at her clit, the other hand tugging her wires, it was all slowly bringing her to the peak.
“Ah!” She let out a breathy moan, “Yellow I’m— Mgh—…Close—” She said through quick breaths. She had to bite her lip from moaning too loud as Yellow’s movements quickened. Cursors, the pace was perfect, she almost felt chills down her spine as she felt the change, “Oh fuck, yesyesyesyesyes…” She babbled.
Meanwhile, Yellow was feeding off the sound of her moans, her own breathing became shaky and uneven, her grinding almost erratic.
And then Dark finally released, her orgasm so strong she began trembling, her shot wide open, rolling back as she rode down her high. Yellow was not too far off, reaching her orgasm almost at the same time as Dark, her movements shaky and messy.
At last, she pulled away and untied Dark’s wrists. As she expected, there were marks. The girl below her was still recovering, sweat dripping around her face. Yellow put her tank back on and picked up her chest plate to put screw it back on.
“So…” Dark spoke up, “Are we doing this again?”
Yellow looked up at her, hesitating on her answer, “No.”
She hesitated.
