SparkMate

🍋NSFW

Pairing: (Transformers) Bumblebee x AFAB! GN! reader

Warning: robot sex, size kink, Bee has both genital, cum play, cum inflation, belly bulge, marking, Bee is a vibrator, reader is AFAB but no specified gender, omegaverse vibes, knotting, interspecies relationship, reader is human, praise kink, song lyrics used for dirty talk, Bee speaks through a radio

Bumblebee will be based off my own Au Of Transformers, Im rusty at drawing robots and mechs. So idk if I'll be able to draw him anytime soon but I kept him vague enough you can imagine different versions of him or even your own!. (Probably not Knightverse base)

Reader and Bee are both 20 (well him in human years)

"Has anyone seen Bee?"

You weren't met with an answer only knowing chuckles from the Autobots. You raised a brow as you looked up at them.

"What did you guys do this time?"

You put your hands on your hips as you send them a scolding look. Ready to hear what new prank they decided to do on the youngest bot. But they didn't spill - none of them held the same excitement or glee they usually did. You looked over to Optimus for help and he kneeled down, placing a hand out for you. You happily climbed on and he raised you to be eye level. He looked nervous as if he was caught doing something he shouldn't. As much as he was serious and calculating he was also a terrible liar when the fate of his kind wasn't at stake. Lying to the enemy? Easy. Lying to friends or family? God awful.

"Optimus…? What happened to Bee?"

Said bot cleared his throat as he looked at the others in hopes they'll chime in but they all dismissed him. Giving him a 'you can do it boss' as they all sat back and watched. He let out a sigh as he finally began to speak.

"He's experiencing what alot of our kind does at his age - when an autobot becomes an adult they are given- uh- cycles."

Your brow only raised further. Confused on what he meant. This only made him slump as he continued talking.

"Where ones spark seeks out another to bind with them, we call them sparkmates and until you find one the cycle will continue, it can cause the Autobot to become aggressive to possible threats to their spark bond and also— Ratchet shouldn't you explain this?"

Ratchet was already tired of his leader's unwillingness and awkward struggling. He rolled his eyes as he leaned down to more of your level. "Oh Primus." He muttered to himself as he moved.

"Bumblebee is experiencing what you humans would understand as a heat cycle, all Autobots experience this though how it may manifest varies, they are commonalities but some use combot as a way of bonding as an example - we are described as an asexual species but that doesn't mean we all unwilling to become intimate with ones sparkmates in a way humans often do."

"So- Bee is…..oh-" you couldn't even muster out the words. A hot flush reaching up to your cheeks down to the rest of your body. You didn't want to them to know what came to your mind. Pretending innocence as you gave him a questioning look.

"Is that why he's hiding away? Because he could start fighting people?"

"Oh sweet naive thing, Bee is not that kind of Bot, you should know that, he's hiding away because he is aroused." Ratchet patted you with one finger, standing back up to full height.

You flushed even harder. "He needs a Sparkmate, right? How long do these cycles last?"

"A month in your time." Ratchet confirmed. The bots were on earth so it made sense their bodies adjusted to different time zones.

"Ok yeah he definitely needs one - uh - do we just find another bot? Like- what do we do?"

You couldn't even believe it. Constantly horny for a whole month? Just the idea made you cringe. It was already frustrating enough but with no way to keep it at bay or have relief? Sounded horrible.

"I think you should visit him, see how he's feeling, this can be a very stressful time for bots, especially for the first time."

Optimus said, lowering you back down to the floor. A knowing tone lingering in his voice.

You looked unsure; what if he didn't want you there? He needed a mate. What if…he didn't want you to be his and that's why he's hiding. Not just from embarrassment but also because none of you were the one he wanted. You couldn't bond with him at all, you had no spark. You were probably the last person he wanted to be near him right now even if you are friends.

There was a sliver of hope in you. That he'd pick you and want you the way you wanted him. You loved Bee more than anything. But if he was in a heat cycle like that then what if he wasn't himself? Did something he'll regret - you didn't want to put him in that position.

"But- what if he-?"

"He will not do anything you won't want, we don't become mindless - just altered."

Optimuses words made you feel better but worry and insecurity still gnawed at you. Well, regardless of anything, your best friend is currently under a lot of stress right now and giving him your support is the least you can do. Even if he tells you to go away, you'll make sure he knows you are on his side and willing to help him find a mate or just listen to any issues be had. If it was anything similar to periods then he could really use that support.

You took in a breath and nodded your head. Marching off to Bee's room as Bulkhead let out a long whistle. You tried to dismiss the flames that licked at your cheeks but it was futile. Your heart was pounding hard against your ribs you were sure it would break.

Once you arrived you scanned your hand. Knocking on the wall as the door slid open. A voice announced your arrival and Bee let out a distressed whirr. The door slammed shut as you ventured further in. The whole room looked as it usually did, organised chaos everywhere but what surprised you were the low hanging cables surrounding what looked like a nest. All his cushions and blankets all tucked together to make a giant bed. Usually he would use his charging pod to sleep but it remained untouched.

The room was illuminated by the pod's blue glow, it mixed in the other lights that gleamed through the long vine like cable's. It seemed he put on all the night lights you gifted him. It made it feel like a peaceful disco. You wanted to laugh at the idea but then you heard another whirr. Reminding you of the situation.

"Bee? Are you feeling okay?" You called out, just stopping outside the nest.

"Ratchet and Optimus told me everything and I know it may be embarrassing but it's natural and I want you to know I'm here to support you - I know I'm no sparkmate but if you need me, I'm here."

Bee let out an annoyed buzz once the last sentence left your mouth. You hesitated, looking back at the door. You didn't want to deal with an aggressive Bumblebee. He may be the smallest but he was one of the best fighters in the team. Besides, you were a human. Just one flick could send you flying.

"Can I see you?" You asked, cringing at yourself knowing what you're doing is very stupid but Optimus said he wouldn't do anything you won't want. You can only hope that also includes violence.

As much as your brain wanted to focus on the fact he was horny and you were too - your gut tried to suppress it by focusing on fear instead. Hoping it would keep you on your toes instead of distracted and leading your actions with getting dick in mind.

There was a pause before he let out a defeated whirr. "come…in."

You inhaled a shaky breath before walking forward. Moving the cables out of your way as you got closer and closer. Stopping as you could finally peak through, eyes falling on Bumblebee's form. His antennae were drooping back as he looked at you with hooded eyes. His mask still covers the lower half of his face. Pillows were hugged close to his form to give him some decency as his fans hummed to life. You worried they were going to break from how intense they sounded.

"Hey, Bee, you holding up okay?"

He nodded. Lowering down so he was on all fours, still keeping himself flushed to a pillow which only made him squirm. You reached out and he leaned forward, letting you cup his face as his fans went even faster. He remained glue to your touch. Letting you smooth your palms over his head, his antennae twitching as his big eyes watched you.

"I'm sorry you have to deal with this, Can I try and help you find a mate-"

He let out a growl. The sound made your heart jump. It was deep and sounded strained, static lingering beneath. Okay, don't talk about mates, noted. You weren't sure how to handle this. It was all so confusing.

"You….my mate…."

You didn't know it was even possible to get any more flustered. You could hear your heart pounding in your ears as his words sunk in.

"How? I don't have a spark."

He nuzzled his face into your small palm as he reached for you. Pulling you closer with ease as your wobbly legs stumbled forward. "Mine."

The robot paused in his actions, still watching you as he let out a timid buzz. "Will you….be mine..?"

You nodded your head. Words Failing you as you stepped closer. Bee didn't say anything, suddenly pouncing towards you. Your back landed with a small 'thump' against his palm as he hovered over you. His mask retracted into his helmet as his face was finally visible to you. You loved his face, when he had his mask on he loved more robotic. You loved it just as much but his real face? It was smooth, dark grey in colour. Scars extending from his lips towards his ears, all left over from the incident where he lost his voice. Broken and ripped at by Decepticons. His eyes were also so wide with wonder and joy even after all he's been through. Shining a beautiful cyan. You loved seeing his real face the most.

"I trust you, Bee."

That gave him the reassurance he needed. His optics lowering down to the baggy shorts you were wearing, you squirmed under his gaze. Realising how you fit so perfectly in his hand. You leaned against two of his fingers; keeping you semi propped up. His thumb brushed against your thigh as it found its way between them. Scanning you up and down as your breath hitched. He found exactly what he was looking for as his thumb pressed down over your clothed core, the tip of his thumb on your clit. Rubbing slow tight circles as it vibrated in light waves.

Your back arched as you grabbed at his hand. Bucking your hips against him, needing more. Too many layers were in your way. Bee tilted his head as he watched you shift away from him, tugging on your shorts. He stopped his movements, worried he did something wrong but he was quickly proven wrong. Kicking your shorts and underwear as far as you could as you laid before him. Legs trembling as he could the shining slick coating your sex. He whirred as a smirk made its way on his face.

Bumblebee was a two sided coin. A warrior and a peacemaker. Shy but confident. He didn't know everything but he was just as good of a leader as Optimus. And as sweet as he was, he also had a cocky attitude. His ego easily stroked, just as easily as it was bruised.

And you knew that look in his optics. Pride swelling in his chest as he saw what he's done to you. You've barely started and yet you feel like a mess. Desperate for more.

"Keep going." You ordered, voice weaker than you wanted as you looked at his digit. It was still vibrating.

You knew he wanted to say something but he didn't. Just moving his thumb back and you let out a cry. Finally able to feel it properly, even now it still felt overwhelming. Able to feel it all over your sex as he tried to keep the focus on your bud.

If there was something Bee was talented for it was patience and watching. Due to being a scout he had a photographic memory and was able to wait days for a target. Even more so, he was built to not blink as much as the other bots. Needing to be able to see every detail and event which made his stare quite intense. It seemed even in this setting; he didn't plan on missing a single thing.

"Can you- Can you use your mouth?" He looked at his thumb and then back at your face. He understood what you meant and smiled. Letting out an excited buzz as he removed his thumb. Raising his hand enough to be comfortable as he rested his chin against the ball of his palm.

Nudging your legs open with his head with ease. You whined at how far you had to widen them, moving them to wrap against the curves of his helmet to get more comfortable. He pressed his lips against you, humming a song you recognized. Moments silence by Hozier, it wasn't Bee's normal taste in music but he enjoyed the song. You remember when you had to explain what it meant to him and he only buzzed. Adding it to his playlist.

It started off slow. Catching your breath as you grinded against his mouth. Sinking into his palm as your legs twitched. Humming along as the vibrations traveled from his throat to his tongue. Lapping at your juices as it engulfed your sex. Sucking on your clit as the chorus played, the intensity going from 0 to 100 too fast making you scream. You couldn't stop panting as the song went back to a slow melody. The peak of your orgasm just hanging by the thread as it slowly went away.

You were just about to catch what he was doing, grinding against the pillow he had pressed against him. His antennae twitching as he let out a low whirr. Trying to move his hips as discreetly as he could.

"Feels good, doesn't it, honey? Keep doing that, I want you to cum with me."

Bee let out a loud buzz. Obviously flustered from your words as he adjusted his hips. You looked down, straining your vision to see a faint blue glow. The head of his spike poked out from the plump pillow.

You whined. Bucking your hips against him, feeling the curve of his 'nose' nudge your clit as his tongue delved into your hole. "Bee- please - need to cum."

He buzzed as he pressed his face as flush as he could against you. Working you back up until the chorus struck you again. A loud string of whimpers escaped your trembling lips as you felt the peak flood back. Crashing against you as your back arched. Desperately grabbing at something to hold, finding his antenna the perfect thing. White flashed before your eyes as you came.

"Good boy, good- good Bee." You lazily patted against his helmet, he whirred at your praise. You felt like your soul was sucked out of you. Eyes fluttering as he moved you back to the nest.

Watching as you wiggled into the blanket's with a hum. He let out a noise of concern but you just cupped his face. Bringing him closer to you as you smiled. "I'm okay, I'm just a little tired."

He nodded but let out a strained whine as he accidentally brushed against the pillow. You were able to see it better now, its size made your heart slam against your chest. Stomach fluttering as you watched the way it twitched under your gaze. Girthy too, thicker than your entire thigh.

As if by magic you felt your energy sprung back inside you.

"You didn't get to cum, did you, Bee? Come here." You cooed, noticing the way he tried to keep moving his hips.

You ushered him closer, he let out an embarrassed buzz as his spike pressed against your clothed stomach. It reached your collarbone. You tried to bite back the moan that threatened to escape you.

You patted his chest plate as you tried to figure out how you were going to do this. Smiling to yourself as he shivered at your touch. His chest was always sensitive due to that's where his spark hid but this was new.

"Roll over Bee."

There was no hesitance. He immediately rolled over onto his back. Watching as you crawled between his legs and got yourself comfortable. Moving a pillow against you to prop you up better. At this angle you could finally see him in all his glory. His spike stood proud but what caught your attention was the plump folds underneath it. Glowing a gorgeous cyan like his eyes. You couldn't stop the drool forming in your mouth. Watching his hole clench under your gaze, completely in awe.

"Oh, Honey, what's this?" You teased, trailing your fingers along his folds. He let out a static filled noise, lips trembling tight together as he tilted his hips into your touch.

You plunged two fingers in, amazed by how soft it was inside. Spongy like rubber but didn't feel like it. Your fingertips felt like they were electric, a tingling sensation coating your fingers. You looked up at Bee who was covered in a dark blue-ish grey blush. Wrapping your arm around his spike as your hands couldn't even wrap around it. Jerking him off as you hugged it closed to your chest. Lowering your head to suck on the head of his spike making him jolt.

You were able to add two more fingers, fastening your pace as his fans turned up to the max. His legs twitching but trying not to move in fear he might accidentally kick you. His back arched as he thrusted upward. Loving how tight your arm was holding him.

Still sucking along what you could. Dragging your tongue along the blue lines that went around his spike like rings. He let out another loud static sound, fingers digging into the blanket's, surely ripping a few in the process.

"Making me……feel..so good!"

He didn't get time to say anything as you pulled the tip into your mouth. Watching the way you could just barely fit it in already- the warmth from your mouth. Feeling your tongue press against him. Curling your fingers inside as you did. It was too much-! His thick load shot down your throat, your eyes widening as you jumped. You gulped down what you could but there was just too much. Pulling yourself off with a wet pop as more cum squirted out. Your chest and face got splattered.

He let out a high pitched buzz as he scrambled up. Grabbing a thin blanket to wipe away his mess. You grabbed his finger and he immediately froze.

You battered your eyelashes at him, making him tilt his head. Opening your mouth as you roll out your tongue. Letting him see just how much he cummed in your mouth. It was all still there on your tongue. It felt like pop rocks.

"You… look good like this.."

There was your Bee. You could sense a shift in him. His anxious state melted away as you made a show of it. Grabbing the thick mess on your chest with a few fingers and sucking on them. Humming as you did.

"Dirty little..human."

He picked you up with ease. Ripping at your chest as you let out a yelp. Placing you on his stomach as you could just about straddle him. Your face was still covered in his cum but he had an idea. Smearing off what he could and began rubbing it down your chest. The pads of his thumbs rolling your nipples as the electric feeling coated them. Making you squirm at the small sparks that now covered your body.

"Why can’t I keep my fingers off you, baby?I want you."

if you weren't Unbearably horny you would have laughed at him playing Beyonce.

His finger moved around, down to your ass. Giving it a small light tap that made you clench. Another small demonstration of how much more powerful he is than you. To him that was nothing but you could feel the light sting. It made you tremble in delight knowing despite this it wasn't too long ago he was whimpering under your touch.

The pressure of his hand made you lean forward. Adjusting yourself so his chest plate didn't dig into your stomach. His finger running against your sex. Covering it in as much cum as he could. The drag of his digit made you gasp as it brushed on your sensitive bud. The very tip of his finger prodding into your hole.

"Open up on the inside, gonna fill you up, gonna make you cry."

The song lyrics caught you by surprise. Flushing as he kept a slow pace. Working you open as you clutched at his chest plate. Rolling your hips back to get more of him. Even just a finger was too much.

He was so big.

He didn't even get down to his knuckle and you felt utterly full. Crying out as he thrusted his finger in faster. Hearing how wet you were with each sloppy squelch.

"Excited?" He teased, already knowing the answer. You hid your face into his chest plate, tears sparkling in your eyes as he kept fucking you as deep as he could.

"Dont- don't tease! You know I want you."

He let out a purr in content. Happy to hear you say it. You only felt your head spin as you peered back. Watching the way his finger sinked into you. Your eyes drifting to his spike.

How would you even be able to take his spike? Would it even fit? Could it even fit?! But yet, the idea of it all only turned you on more. You were just barely able to process the movement of his chest, revealing his spark just enough for you to see it. You sat up making him hit right into your g-spot. Jolting in surprise and pleasure as you let out a moan.

"Your spark-"

You couldn't even speak without becoming breathless. Whining as he removed his finger and scrunched himself up as he semi sat up. You sex pressed along his spike as you were forced to move back making you both moan.

He positioned it to your entrance, guiding your body up so he could put it in properly. Watching you squirm as you rubbed your soaked folds along the tip. What was left of his cum was still dribbling down his spike making it lubricated enough for you to move.

His thumb came back to your clit, sending a low vibration to it all over again. Holding your hip with the rest of his hand as you sank down. The fat head of his spike just pushed in with a small grunt. It felt like centuries. Slowly moving lower and lower as you feel yourself get completely stretched out. Trying not to clench down and keep your breathing steady as he kept playing with your clit.

You let out a strained gasp as you felt yourself completely sink down to the base. Both of you stilled as you got adjusted to the sensation. Bee was whimpering as he used all his will power to not jerk his hips. If you kept clenching around him like that he was sure he was going to cum again.

He held your hips with one hand, keeping one finger under your ass and the rest on your hips and his thumb remained on your clit. You did your best to move on your own, keeping a steady pace up and down. Each hit hitting your pleasure spot as you arched your back. Clawing at his chest plate as his spark reached out for you. Sparks of electricity running up your arms as you mewled. It was warm, leaving a tingling sensation in its wake. It caresses your skin as it seeps into your very being.

Your pleasure doubled as if you could feel his own. With heavy eyelids you looked at him. Your mouth parted as a light trail of drool dripped from your tongue. The tears that beaded in your eyes became fat drops as you slammed your hips down. Unable to reach the base due to him supporting your ass. You slapped at the finger as you couldn't stop strings of moans flying out.

He got the message and moved his finger. Letting you bounce to the base. His fingers dug into your flesh as you grew closer to your peak. For sure leaving large bruises but at this point you couldn't care. You were happy to show off any mark he left you.

"Good Bee, so good- going to make me cum."

He whimpered at your words. You latched onto his antennae, which he bent towards you, completely stretching out your body as he ducked his head. You were able to pull yourself up until the tip was the only thing left before slamming your back down. The sudden fullness made the tightening cord in your gut snap.

Throwing your head back as your fingers brushed against his helmet. Grabbing at his thighs as he held you up. Your orgasm left your head dizzy. Falling back as he thrusted up. Chasing his own release, as he whirred.

"Mine." He growled out as he pushed down. Snapping his hips into you. His orgasm is just as strong as the one before. Completely coating your walls. Whispering as he fucked it into you.

What made your head snap down was the feeling of his spike bulging inside you. Right at the bottom, locking you in place. His thumb brushed along your stomach making you follow his movements. Whining as you saw your stomach bulge out. Pressing your own hand to your belly to feel the head of his spike. The bump growing ever so slightly as more of his cum pumped into you.

"Is this normal?" You gestured to the bump peaking out of your sex. Lifting yourself not to much avail as you were completely locked to him.

He nodded his head. Looking bashful as he kept caressing your stomach. You smiled at him as you pressed your face to his chest plate. His sparks energy still threading into your veins keeping you in a constant glow. Absolutely hazy from the pleasure.

"Thank you for choosing me to be your Sparkmate."

He shook his head. "Perfect…for me…" thanking his flexibility as he completely towered over you. Tilting your head back, pressing his lips to yours. Or atleast, due to his size, his top lip whilst the rest was pressed against your chin.

You giggled into the kiss as you grabbed his helmet. Scratching under his antennae making him purr. His tongue poked your lip and you happily let it in, choking around it as he put only half of it in. It was able to touch every inch of your mouth, feeling the tip in your throat.

Your lips hungrily moving against his, clawing at his helmet as you breathed through your nose. You felt the knot grow tighter as he muffled your moans. When you finally parted you were left panting. Shakily gulping up air. Flopping down against his chest where you traced your fingers along the plating around his spark.

"So….um- how long are we going to be connected like this." You bashfully asked, fumbling with your words as you noticed a flicker in his optics.

"Not that I don't enjoy it-! I'm just wondering!"

"I don't know…" He paused, hugging you close to his chest as he suddenly moved on all fours. Pushing pillows underneath you so you're fully supported and propped up.

"But maybe… another round..could… loosen it up."

You let out a small noise as you trembled. A familiar throb coming back as you grabbed at his chest. "O-okay-!"

Ratchet leaned away from the door. Just missing the sound you made as Bumblebee started moving.

He coughed into his hand and looked at the other bots. "They seem to be doing just fine, I think it's best we leave them for the next….few hours."
