Late Night Maintenance

Summary:

Hello! I'm new at smut and such and would love some feedback. Of course, my first would be these adorable creatures!

After a rather rough Birthday party/event Sun and Moon need some maintenance and an updated functions report ;)

Chapter 1: Sunrise

Chapter Text

You didn’t know whether to laugh or cry. You had been asked to work overtime in the daycare after Sun, a rather rambunctious and bouncy animatronic, had gotten messy and torn up internally from a rowdy birthday party. Well yes, you are the robot’s personal technician, you still didn’t like staying any later than you had to due to the creepiness when the lights were on half-power.

 

You approached the sitting animatronic, he was curled in his backstage from the platform that was above the ball pit. Toolbag in hand as you made your silent footsteps louder. Sun turned, his ever-present grin seemed sadder as he bounced up at the sight of you yet his voice box keened in a static whine. You smiled, taking his hand, he was warmer than his counterpart.

 

“Hey, Sunny, rough day? Those kids can be mean.” You grinned as the animatronic sat, crossing his long legs, his faceplate spun, tilting his head before shaking his head as another whine poked through. Eyebrows creasing, you ran your fingers along the seams of his fingers, the bot began swaying as he hit a silent beat, fingers twitching and fluttering. Untying the fabric around his wrists, Sun took care of his little bits of clothing, laying them down neatly as the bell jingled and clacked against the concrete ground.

 

“You love them anyway. I know.” Giving another smile you checked his other arm and found sticky splotches across the animatronic’s forearm, “There we go, is there anything wrong? Or do you just need it cleaned?” You turned away, crouching down to drag your toolbag closer. Sun chittered, clicks, and whirs. He seemed satisfied with himself as he graciously placed a hand on his chest and chittered happily, swaying back in full swing.

 

“Uh-huh,” You nodded to his chittering, wiping his arm with your rag as you continued your inspection. His voice box was damaged, you just didn’t know to what extent just yet. Running your hand up to his shoulders you moved the ruffles away, tugging to see if they disconnected or not. They did not. Despite this, you put your fingers in blind, letting your small hands map the unseen inside of the animatronic. You could feel small bumps and softer moldable plastic, pressure sensors.

 

His swaying stopped, shuddering as you brushed against a particular sensor on his endoskeleton. A click and a whine turned to static as you snagged your fingers, hoping that whatever substance these kids had gotten over him wasn’t anything damaging. Hopefully just glitter glue and and whatever juice they serve. Sun’s hands fluttered across your waist, pulling you closer as his faceplate spun before settling. His eyes peered into yours as you held your breath, feeling the hot vents he let off. The self-cooling system was working, another box off the list.

 

“Sunny, be patient. I’ll get your beautiful voice in working order soon.” You patted the side of his face, and his head dropped, rubbing into your chest as you barely avoided the unsharp yet still-pointed rays. Running your fingers across them, his legs kicked out impatiently, as you pinched one between your fingers, testing. A shudder was you’re only indicator to the exploration.

 

You had read and studied his blueprints but there was never a full report on the extent of his sensors or functions. Everyone was too scared, for whatever reason. The animatronic keened again, long arms wrapping around your torso. The ones they did have were severely outdated. Older models of what the dual personality animatronics used to be.

 

“Sunny.” You tried, checking the wires that neatly poked through his neck, there were a few loose, likely yanked, you’ll need to remove his face. Thankfully his voice box resided in his chest, but whichever wires were pulled were surely the cause of something eventually going wrong.

 

The animatronic looked up, after you stopped your ministrations, squeezing your torso. Again? Your fingers caressed the thin seam that held his rays, watching as they shifted up and down.

 

“You want me… to do that again?” He nodded frantically, stretching his neck back to keep from jabbing you. You nodded and touched again, running your fingers along the edge as your other hand went under and between his rays at the bottom, looking for the clasp that would release his face mask. It was a small latch that required a small flathead, but your fingernail worked just as well.

 

His static whines were quieter as he shuddered against you, his hands fluttering up from your torso to your hips, massaging as he keened as you pinched the base of another ray. They were there to sense any flying objects and to scan and run physical diagnostics on guests. They were very sensitive as well, it seems. Expected, you absentmindedly scraped your nails, testing the soft plating, and Sun buried his head into your chest once more, nuzzling as warped chitters continued.

 

“I’m sorry, that probably hurt,” You muttered softly, tilting the animatronics larger head up, rays shrinking inwards before spinning slowly, meticulously. There was a pause as your fingers finally located the latch, nail slotting almost perfectly. Sun’s grip on your hips tightened, fingers tapping a silent song.

 

“Alright,” You felt his face mask hiss, he stilled, shuddering as the cool air hit his endoskeleton, his teeth stayed, as did his rays, and eyes, you stopped touching and tried to lean over to grab your toolbag, but Sun wouldn’t let go, “I need my tools, Sunny.”

 

Without letting you go he used his leg and lifted it, his endoskeleton face peered up at you. He chittered as he tilted his head. A hot vent escaped as you ran your hands behind his head, tugging on the loose wires. Slipping your nimble fingers through, you reconnected the unplugged clips. A satisfied keen escaped his voice box. Two faint biolights behind his teeth lit up. His mouth opened, and a long silver tongue sneaked out and gave a long smooth lick on your neck. You gasped, a squeak escaping your mouth as you felt your ears burn.

 

He took that as a sign to explore further, his right hand cupping your breast, fingers massaging and pinching, rolling your nipple through the cloth. A gasp escaped, clenching your jaw you focused on the task at hand.

 

Of course, that’s what it was. You drop the tool on the ground, hooking his faceplate back on as it clicks, spinning quickly as he chittered. His teeth separated again and his tongue gave a warm lick from the collar of your uniform to your chin. Fuck, heat coiled in your gut spreading to your groin as you rubbed your thighs together, a shiver made your teeth chatter unable to hold back a groan. You now realized what exactly you had been doing to the animatronic your blush burning hotter as his grin seemed more teasing.

 

His hands slipped away from the slow ministrations, caressing your thighs as he slowly spread them apart, a huff left you as you shuffled closer, pulling your legs up to wrap them around Sun’s waist. Pulling you closer as he prodded and nibbled into your neck.

 

“You sneaky bastard.” You huffed, pinching two of his rays as he let out a static whine. Two can play at this game. Leaning forward as his tongue slithered back into his mouth, you opened your own, letting your breath hit the rays and he kicked out again. You, surprisingly, toppled back, tongue just centimeters from his ray as he pinned you down. Grinding down into your hips, Sun whined, rolling into you as his grip tightened.

 

“Now now, Sunny,” You whispered, a smile on your red face, the animatronic growled out static, fingers sliding under your wrinkled shirt as he pinched and squeezed your waist, it tickled. You laughed, not the reaction he wanted, another hand wrapped around your throat, squeezing. Your eyes snapped open, shit. You gasped, the lack of oxygen burning as his other hand pulled your work shirt up, pinching your nipple.

 

“S-Sun– unny-” You gasped out, tongue lolling out as drool slipped out, his tongue came and swept the fluid, spreading it over your lips. It eventually curled around the pert nipple, saliva coating your chest as spots danced in and out before Sun whined, releasing the torturous caresses as he backed up from dry humping you. You coughed a moan just caught in your throat, yet the sadness of the now non-existent pleasure took over. Surprisingly, you didn’t want it to stop, the heat that coiled in your gut becoming more noticeable. You could already feel the forming bruises but sat up.

 

“Sunny, it’s okay.” You reassured, voice wheezing as you caught your breath. You reached a hand out as he pulled you closer, a few chitters pitched in volume. You hum, looking at him with a reassuring smile.

 

You ran a hand along with his faceplate, leaning forward as you stuck the tip of a ray in your mouth. The animatronic jumped, static escaping as his fingers fluttered to your thighs once more. Taking the chance, you unbuckle your belt, letting Sunny do the rest as he rips your now-ruined pants off. Dragging you closer, Sunny rolled his hips again, hunching over as he flipped you over. You squirmed and pinned your face down, ass in the air. You gasped as his hand cupped against your, somehow still intact panties. Shoving his hand between his still-rutting hips, palming at your hole.

 

“O-Oh fuck. S-Sunny please,” You begged, pushing your hips back as he pulled the fabric down, he paused, warmth leaving as he shifted. Your blush burned brighter as you craned your neck to look back. Seeing his tongue slither out. You knew if he had his working voice box, he would’ve thoroughly chided you for your language, but you really couldn’t give a fuck-

 

A hand pushed on the middle of your back, making your arch as another wrapped around your throat again, a warning click as his fingers slid up to push into your mouth. It was warm as your tongue swiped over the pads, and then more fingers wiggled past your lips, massaging against your tongue. The length of his fingers pushed deeper, hitting your throat. You choked, gagging slightly as he pulled his fingers out, his other hand fluttering and massaging your throat soothingly. Saliva connected you both before it snapped. Your lips were wet with saliva as you licked your lips.

 

Sunny put a slick finger past the folds, tracing the rim of your hole before pushing in, curling experimentally as your walls fluttered. Your mouth opened in a soundless moan, pleasure sending lightning strikes through your body. Then another finger and another. Four fingers pumped in and out, a wet squelch echoing in the nearly quiet backroom. You choked and wheezed on your gasps, eyes sliding towards the curtain. They may not be in the daycare but the stage leading to the ball pit was not soundproof. Another gasp involuntarily leaves your throat, rumbling against his hand as he gives a slight squeeze. Oh god– it burned so good-!

 

The fingers inside left with a pop, leaving you to agonizingly clench over nothing. Sunny chittered above you a new appendage sliding into your hole, wriggling deep inside. You whined, jerking your hips back it was pitched and drawn out as it pushed and prodded deep inside. Without pulling his smooth tongue out, he lifted your hips, turned you over, and kept your hips on his face, one leg resting on his shoulder and another being held up by his hand. The hand holding you up dug into your hip as his tongue pumped in and out.

 

Your eyes rolled back, hands grasping Sunny’s arms for support. His eyes focused intently on your red face as you looked up to him. His tongue became ruthless, curling and pulsing as he pushed his faceplates flush against you. A whine escaped your throat as he swirled his tongue at the rim of your hole before pushing back in, setting a brutal pace.

 

You could feel a familiar pressure building in your gut, slamming a hand over your mouth as a loud moan escaped your throat. God –

 

“S-Sunny. Sunny! I’m g-gonna-” You keened, thighs slamming together as the rays on the side of his face dug into your thighs, it jammed sharply, leaving pinpricks of blood. Waiting a moment, Sunny slid his tongue out, dripping with slick. You huffed, breathing heavily. Sunny’s tongue swiped along your thighs, picking up the blood as his tongue slid back into his mouth, teeth clicking shut.

 

Sunny let you go, helping you sit up before he pulled a pair of his spare pants towards you. You nodded, grateful, not yet ready to speak. He chittered, pointing to his chest. Right.

 

“Okay,” You breathed out, sitting down as he leaned over and unhitched his chest covering, there. His voice box was displaced, just what the hell happened? Reaching his hand in, he pulled the few wires still connected off and held the little device in your palm, looking it over. Despite the soothing exhaustion overtaking your body, you were still curious. Reaching a hand in, you ran your fingers over the endoskeleton, watching the way Sunny shuddered, no longer able to make noise, his hands came back to gently massage your thighs. His joints clicked rhythmically as you reconnected the wires, fingers lingering on the internal support struts.

 

Closing the hatch, you overlooked the rest of him, having him pull off his pants and overlook his joints. All good. You patted his knee, and the animatronic pulled his pants on, standing as he twirled, happy. You stood, legs wobbling as you adjusted the long jester pants.

 

“F-Friend!” His voice box whined, cutting slightly before hitting his chest, “ Did you feel good, Doll ?” Sunny grabbed your arm, twirling you as he pulled you into a hug. You giggled, wrapping your arms around his thin waist, supporting yourself. The nickname made your stomach flutter. Yet the lights flickered, checking the time on your watch, oh.

 

“Lights off?” You whispered and Sunny nodded, knowing you were safe you still needed to evaluate his nighttime mode. What fun that would be.
