Bump In The Night

Summary:

Slight continuation to In The Name Of Science

After her encounter with Andi, Guinevere finds herself even more curious about humans and their reactions to stimuli. She decides to take matters into her own hands, completely unaware that she's being spied on.

Work Text:

Andi decided not to tell Frankie what had happened between her and Guinevere. They had a mission and she didn’t want personal issues coming between them and finishing it. 

 

At least that was what she told herself to feel better.

 

Andi knew Frankie. Andi knows Frankie. They’ve been glued together since they were in school, they knew everything about each other. Frankie was impulsive but even so, Andi could always gauge her reactions to things.

 

This was far above those things. Andi didn’t have a single clue how she would react if she told her what had happened. Would Frankie lash out in anger? Or retreat in betrayal? She couldn’t decide which was worse.

 

So she’d keep it a secret.

 


 

When Frankie came home from the factory, she was exhausted. All she wanted to do was lay down and sleep for the next decade and wake up in a world where everything was less confusing.

 

She hated the way she was feeling. The way she couldn’t even tell what she was feeling. She felt sick for backstabbing Sparky, but also kind of free to be away from him. The freedom wouldn’t last, she knew. He’d send the others after her, which made her feel so anxious she thought her heart would stop. But even then, something felt… lighter.

 

Her stomach churned with all the emotions. She’d eat later, she needed to sleep.

 

Frankie didn’t even bother taking her dirty clothes off before disappearing under the blanket. She’d just wash the sheets in the morning.

 

 

Frankie turned around, facing the wall.

 

That wasn’t right.

 

She groaned, flipping over onto her side.

 

Then to her stomach.

 

She curled her legs up to her chest, and then dropped them back down. She starfished, she crossed her ankles, she tossed and turned every which way.

 

She could not fall asleep.

 

Frankie groaned before throwing the blanket off herself. She refused to stand up, crawling to the edge of the bed and reaching towards the bottom drawer of a nearby dresser. She opened it and shuffled through the unmatched socks before pulling out a chunk of plastic.

 

Her shitty little bullet vibrator. It wasn’t much, but it got the job done. 

 

Hopefully a good enough job to put her to sleep afterwards.

 

Once again she was faced with the dilemma of whether or not to expend the energy to do something as simple as taking her pants off. Frankie opted not to and turned the vibrator to its highest setting, just so she could feel it through the denim. 

 

She lounged back, legs spread lazily while her hand found its way to her clit, massaging the plastic into it with no real rhythm. She hummed, honestly kind of bored just waiting for the orgasm to come so she could get some decent rest. 

 

There was a loud mechanical clanking sound and her bedroom door was slammed open.

 

Frankie bolted upright, thankful she hadn’t stripped down as her heart beat out of her chest.

 

Guinevere looked as though she had lost her balance at the doorknob and haphazardly fallen into a pile of limbs on the floor.

 

“Gwen!” Frankie’s face turned bright red.

 

She stood up, trying to make her way over to the android but paused when she heard a loud thump on the floor.

 

Her vibrator had rolled off the bed, nestling itself at her feet. 

 

Guinevere stood shakily, walking towards her. Frankie panicked and reached for it, but Gwen was too fast. 

 

She picked it up in her hand, twirling it around her metal fingers with little clicking sounds. Guinevere’s index found the power dial and spun it. The vibrating started.

 

Frankie thought she might die of embarrassment.

 

Gwen spun the dial, making the vibrations heighten and lessen in seconds. She gave a curious look to Frankie, one that was almost puppy-like. 

 

Frankie bit her bottom lip, looking at the ceiling.

 

“It’s, uh, a massager.” She half-lied. “For like, your muscles, you know? Feet and shoulders and… stuff.”

 

Guinevere chirped. Frankie wasn’t really sure what the sound meant but her blush grew deeper when she saw Gwen trying to replicate what she told her. The android pressed the vibrator against her shoulder, right into the exposed wiring. She hummed, closing her eyes with a dopey smile.

 

That… worked?

 

“Does it feel… Good?” Frankie asked, slightly amused. Guinevere just nodded, rolling the piece up and down her body. She laughed as it made its way down her sides, as if it was tickling her. 

 

Frankie giggled with her, thankful the weird atmosphere was gone.

 

Until it wasn’t.

 

Guinevere practically jumped on Frankie, pushing back onto the bed with the android halfway in her lap. Frankie held her breath.

 

It wasn’t like Guinevere would ever intentionally hurt her, but when she was close up like this it was hard not to be intimidated. She’s huge.

 

Her metallic fingers pressed the vibrator into Frankie’s side, tickling her.

 

“S-stop-!” Frankie giggled, trying to bat her arm away. But even with only one hand, Guinevere was much stronger than her. She explored her body, running the tool up and down her shoulders, chest, and stomach. Frankie couldn’t catch her breath.

 

Until Guinevere ventured lower.

 

Frankie gasped when the vibrating hit her clit, jump-starting her previous session.

 

It didn’t take much to bring her back to that peak.

 

“Wait-“ she pleaded, but Guinevere had already caught onto her reaction and was curious about it. 

 

The android tilted her head, rolling the vibrator in little circles against the bottom of Frankie’s overalls. Suddenly Frankie remembered how tired she was. Much too tired to fight it.

 

Besides, what’s a little secret between two friends?

 

She arched against the movement, whimpers falling from her lips. She was so tender already, so needy.

 

She told herself it had nothing to do with Guinevere. Sure, maybe getting groped by someone you looked up to your whole life would be exciting for other people, but not for Frankie. She was level-headed. Her and Guinevere were equals, friends.

 

No amount of lying to herself would make her believe that, but she tried regardless.

 

She was so wet. She could feel it dampening her panties and chafing her overalls. There was no more denying it, she could see it start to leak through both layers and she knew Guinevere would take notice. She takes notice of everything. 

 

Before she could even realize it, Frankie’s pants were being pulled off and discarded. 

 

She shivered at the chilly air on her exposed skin. Guinevere moved backwards, scooting off the bed to kneel in between Frankie’s legs. Even on her knees, Guinevere was still almost eye-level with her. She moved her cold hand towards Frankie’s panties, hooking around them and pulling them to the side. 

 

She just stared at the pink, wet flesh of Frankie’s pussy, sitting silently. Guinevere hummed a little noise before opening her mouth and licking a stripe down her bush. Frankie tensed, hand coming to grab Gwen behind the head. “S-shit…” She whined, staring at the blue blood that was staining her skin. Guinevere’s mouth was so wet.

 

Frankie couldn’t help it, she pulled her back. She ground her clit against Guinevere’s tongue, reveling in the little noises of curiosity she made under her. Fuck.

 

Guinevere’s tentacles reached out to wrap around Frankie’s waist, holding her in place while her tongue dipped and circled her, lapping up the taste with hunger. 

 

Humans were so interesting.

 

With her hand now free, she brought the still buzzing vibrator to her stomach. She presses it up under her metal casing and into the heart of her mechanics, a big knotted ball of wires and organic organs. 

 

It felt good. It felt unlike anything she had ever experienced. Like getting a coding update, but a million times better. 

 

She was drunk off the pleasure, content to bury herself further into Frankie without a single thought.

 

Frankie, in turn, thrust faster against her face. Her pace was erratic and her whole body on fire. She whimpered, unable to form coherent words before cumming hard, her orgasm loud and shaky. 

 

Guinevere didn’t stop. 

 

She pushed her back against the bed, forcing her legs to wrap around her shoulders as she kept going. She pulled orgasm after orgasm from Frankie, not stopping from the shaking or the garbled cries and moans. She wasn’t done with her. She didn’t know what this feeling building up was, but she wanted to reach its peak.

 

Guinevere froze, the light of a thousand neurons cracking completely covering her vision. Her whole body buzzed, tensed, and then it was dark.

 

She passed out, her 400 pound mass of metal body thunking onto Frankie’s bed and shattering the frame.

 

Frankie groaned, completely limp. She’d deal with it in the morning, she told herself before rolling onto her side, pants still down, and falling asleep.

 


 

“G-Guinevere-“

 

Frankie panted, the noise obstructed through the wall.

 

Andi knew she shouldn’t be doing this. She knew it shouldn’t have even crossed her mind to eavesdrop while Frankie thought she wasn’t home, but they were being so loud.

 

She had gotten curious.

 

And the curiosity had turned into… something else.

 

Andi didn’t know how it started, just that she was depraved enough to hear moans through the bedroom door and immediately stick her hands down her pants. 

 

She was disgusting.

 

Crouched hidden from the doorway and from getting caught, she had her ear pressed against the wall and two fingers in her pussy. She rocked back and forth on them, thumb circling her clit as she imagined what they were doing behind her eyelids.

 

She never imagined Frankie would be so vocal, and she blushed at the thought. The wet, slick noises went straight to her throbbing core and she bit her lip to stop herself from whining when she came. The spend soaked her fingers and clothes. 

 

Andi brought her hand to her mouth, licking her own cum up before walking away and pretending none of this ever happened. 



Notes:

I don't have a beta reader, I didn't run this through a grammar checker, I didn't even read it over again before posting so if you're mad about typos in a robot porn fic maybe you should just die idk
