Chapter Text
Dinah’s been aching recently.
Well, it wasn’t necessarily aching in a bad way. It was..just an ache she couldn’t quite place.
Sure, there were aches should deal with. She’s been around long enough to distinguish which ache was which, and she definitely knew how to deal with said aches.
But now? It was like she couldn’t deal with it anymore.
It plagued her. Like a curse, but a sexy curse at that. And she knew exactly who’s been making her ache that way. Who’s been making her valve clench and her lubricant almost trail down her thighs. She would’ve usually hated feeling like that, especially since she was so new to the yard, but then again, she never usually let others know how desperate she was. She never would.
Well. That was until she started to date Greaseball.
The new reigning champion.
The diesel with the prettiest face, the biggest muscles, and the dorkiest personality she had ever known. Seriously! He was the hottest engine she ever knew, and ever dated. It was a miracle no other coach or freight had gotten to him first, and she thanked the Starlight for that fact.
Even though he plagued her with those sexy thoughts, always late at night, or even when she was standing next to him. It was like he was teasing her, letting her know he knew exactly what he was doing. And Starlight, did she want to find that out.
So, when it was break time, she rolled up to the part of the yard she knew Greaseball would be coming from, and she put her hands in front of her when Greaseball spotted her.
"Dinah?" He snorted, rolling up to her and tilting his head.
The little dining car had never really token the opportunity to face him when he usually got off his work, but he wasn’t going to complain. "Hey champ." She grinned, placing her hand on his rather big chest plate and giving it a few light pats. "Whatcha doin’ here so late?" He hummed. Dinah shrugged, biting her bottom lip lightly before glancing up at him through her lashes. "Oh, well.." She mumbled.
"I was thinkin’, maybe we could.." Greaseball felt a small smile crawl on his lips, and he titled his head the other way. "Are you..?" He whispered, leaned down to be face to face with her. Dinah felt her eyes widen, her face flush, and her core tighten..along with her valve. "Askin’ me out darlin’?" He chuckled, raising a brow. Dinah nodded not a moment later, her face burning hot like Rusty’s boiler.
Greaseball hummed, pulling away to lean on the wall next to him. "I mean.." He mumbled, his face now flushing as he chuckled to himself. "Yeah." He nodded, leaning away from the wall to take hold of her hands, giving her this dopey grin that made her do one in turn. "Yeah. Sure." Dinah nodded, her eyes fluttering as she felt her core burn brighter. "What time..?" He mumbled quietly. Dinah shot her head up and blinked.
"Uh—" He coughed. "What time should I be there?" He corrected himself. Dinah glanced down, tapping her skate on the floor in thought, before nodding to herself. "7:20." She blurted out, in all honesty she said the first thing that came to her head, and it seemed to work. Greaseball nodded, licking his bottom lip unconsciously.
Dinah watched.
"Yeah, okay." He nodded again. "I’ll see you?" He smiled again, shrugging. Dinah giggled. "I’ll see you.." She agreed, and went up to kiss under his chin up on her stops. Greaseball froze, his face flushing as she pulled away and rolled off.
Greaseball felt his smile return, uncharacteristically soft as he giggled lightly.
Dinah had been waiting in her shed for a while.
She was cooking up a little meal for her and Greaseball to enjoy, and with the small amounts of snacks she had made, she believed she had almost everything set for the date.
All she needed to do after was wait.
Dinah pulled out the baked steak that was importantly made specifically for diesels and placed it onto a plate thst she had pulled out of her display chest plate. She then hummed, added some sauce that she knew would get her champion going, and made a plate for herself. This one not made for diesels.
What could she say? She was prepared.
Dinah was finishing up placing the drinks in the table before she heard her doorbell ring. She grinned wide, and placed the glasses on the table before she skated over rather quickly towards the door. She huffed, fixing her hair and skirt, before nodding and opening the door with a soft smile.
Greaseball grinned down at her. His smile as beautiful as ever as he waved sheepishly. "Hey, hun." He greeted, following Dinah inside as she took his hand and rolled out the doorway. Dinah bounced on her wheels, making Greaseball chuckle. "I made you some dinner!" She softly exclaimed. Dinah knew how her champion got when people yelled, she’d seen it first hand, and it made her deeply upset whenever he’d confess to her when they were cuddling in bed together late at night sometimes, or radioing her when it got bad.
So she made the effort of lowering her voice when she could. "Yeah?" Greaseball raised a brow, before he followed Dinah to the kitchen and was pleasantly surprised at the spread of food. He blinked, chuffing in disbelief before he shook his head. "Ah, y’ didn’t need to do all that for me.." Dinah shook her head, leading him to sit on the comfy chair before giving him a tiny kiss.
"It’s all for you darlin’." Dinah cooed, before kissing him again. This time a bit more passionately. Greaseball shrugged, his face flushed as he grabbed the steak and but into it, discarding the utensils next to the plate. Dinah blinked, grimacing softly before huffing and rolling her eyes.
Diesels.
She took for knife and fork and began cutting into it, giving Greaseball a playful roll of her eyes as he chuckled lightly. Mostly focused on tearing the steak like it owed him money. Dinah, more refined and proper had stabbed the fork into the steak and bit into it. Humming lightly. "So," Greaseball started, grabbing a bottle of oil and gulping down half of it in his anxiousness. "Whatcha planning on doing after this?" He questioned, only asking so he knew what he was getting into. He liked..well..being told ahead of time.
You.
Dinah had thought in her head. Almost choking on a hard piece of steak, but successfully managing to cover it up with drinking some oil as well. "Oh, you’ll see.." She shrugged, giving Greaseball a smug smile. Greaseball hummed, before continuing to eat the rest of his steak. Eyeing Dinah with a slight look of suspicion.
After the both of them had finished eating, Dinah dragged him over to the living room. Sitting him down on the couch and grinning down at him. She had brought some snacks, and had put them on the glass table in front of them. Greaseball snagged some chips, grinning up at her as well. Dinah rolled across and sat down next to him on the couch, before scooting closer and grabbing the remote.
Greaseball wrapped an arm around Dinah’s waist, pushing her close. "Wanna watch a movie?" She mumbled. Greaseball shrugged. "If it’s horror m’not comin’ back." He deadpanned, but teased her with a grin. Dinah blinked, before chuckling dryly. Surely, the nerves were getting to her today. The dining car turned on the tv and scrolled for a bit, before clicking on a movie that looked mildly interesting. "You fine with this?" Greaseball glanced over and nodded.
As the movie had rolled its intro, Greaseball opened the bag of chips and grabbed a handful. Stuffing them in his mouth and chomping on them loudly. Dinah had wanted to see what the movie had entailed, but the chomping was getting on her nerves. She didn’t say a thing though, obviously because she didn’t want to spoil the date, so she glanced over at him, placing a palm on her chin to make it look normal.
The movie she picked was then discarded from her mind, placed deep in the backspace as she began to just..look at Greaseball. Gulping down those chips like an unattended trainlet made her core flutter, and putting his skates on the table with a slight loud clank. Greaseball was definitely watching the movie, as he paid no mind to Dinah’s staring.
He was used to it by now, but maybe the movie was really entertaining?
Yeah, sure. She’d say the movie was entertaining. Especially since Greaseball was chuckling every minute a character from the movie spoke. Or when a music cue played, she didn’t know what for, he laughed even louder. Dinah bit her lip, and decided she wanted a snack of her own to distract herself from that beautiful face he had. Though, as she turned her head to look at the array of food she paused.
Was that..?
Dinah felt her face flush.
Was that a moan?
Dinah gaped, before slowly turning her head over to Greaseball who was stiff as a board. She then glanced over at the tv.
Both characters, who she never gave attention too, were now fucking. Fucking in the front seat of the pickup truck like it was a national sport. Dinah flushed a darker shade of red, the snacks now entirely forgotten as she stared. Greaseball, who had his arm around her, had tightened his grip on her hip. Probably in shock. Dinah sat up straight, before blinking hurriedly.
Starlight, what a first date huh?
Dinah cautiously glanced up next to her, and Greaseball looked…conflicted? His eyes were wide, yes, but his body was unnaturally stiff as he glanced at the tv. His legs uncrossed from the table and his skates smacked onto the carpet beneath them. Dinah bit her lip, before placing a hand lightly on his arm. Rubbing soft circles with her thumb. "Greaseball?" She murmured.
The diesel in question grunted, shaking his head before turning to look at her. His face flushed and his teeth held in a tight grit. "Yup?" He rasped out, glancing away to cough into his hand. Dinah tapped her fingers down his forearm, lightly tracing his metal lining before leaning in closer, her eyes fluttered as she felt her core grow hotter and her valve clenched beneath her crotch plating.
"I think you got a problem.." She pointed out, trying to hide the grin she felt as Greaseball coughed harder. His muscles hardened as he glanced back her in disbelief. "I—..huh?" His voice cracked. Dinah shrugged, now sliding her hand down towards his thigh, and humming. Greaseball’s eyes couldn’t have been more wide, and he glanced down at the hand on his thigh before glancing up at her.
"This movie’s gettin’ you.." She closed her eyes for a moment, trying to calm her raging core. This was her chance! Thank the Starlight for the movie she picked. She leaned in closer, and Greaseball clenched his thighs, his lips twitching in an expression she couldn’t quite place. "It’s gettin’ you hot?" She cooed, and slowly tapped on the gold plating on his thigh. Greaseball stared at her, blinking slowly.
"I mean.." He stammered, shrugging helplessly as Dinah began to grin. "I think I could..help." She raised her brows. Waiting for her diesel to give her the okay. Greaseball’s mouth gaped and closed, his face heated up intensely, so intense his fans whirled on.
"Dinah." He choked out, almost like warning.
"Greaseball." She countered.
Greaseball licked his lips, letting his head fall back onto the couch with a hiss. He could feel his own crotch plating becoming increasingly tighter, and the teasing from his new girlfriend was making it worse. Dinah tilted her head sweetly, knowing how east her boyfriend was to being riled up. The dining car waited before making another comment she was sure would file him up even more.
"You want me Greasy darlin’?" She cooed, and was about to pull away before Greaseball growled low, biting his lips twitching in in a form of frustration before pulling her close and kissing her passionately.
Oh.
That was a yes.
Dinah moaned low, kissing him back. Her hands went up to his face, pulling him in as he groaned and pulled her even closer by her hips. She complied, and crawled up onto his lap. Now sliding her hands down to drape them over his shoulders. Greaseball’s hands on her waist had tightened, trying to pull her in so close her body was pressed up against his. Dinah huffed as her back arched, and she pulled off the kiss for a moment to slowly kiss at his chin and suck on his softly.
Greaseball groan lowly, and as Dinah went back to his lips, he let his tongue slide softly along her bottom lip as his engine purred lowly. Dinah jolted slightly, before opening mer mouth and letting his tongue slide inside. Greaseball wasn’t very used to kissing, he never really kissed other coaches or passenger cars before. So his motions were slow, messy, and downright desperate. Dinah could tell this was something new for him, with this being for her as well.
Dinah swirled her tongue around his, just as uncoordinated and messy as him. Groans, whimpers, and the noise of their lips pressed together were all there, with the noise of their lips tv fading in the background before Greaseball had went and pinned her onto the couch, letting out a long groan deep from his throat. The dining car’s legs trembled lightly, and she lightly ground her clothed crotch against his. Greaseball gasped, before grunting and grinding against her as well.
Greaseball’s grinds were more stiff, like he was too out of it to do anything her could usually do properly. Dinah grunted, trying to match his grinds, and Greaseball’s head fell back before huffed. "Do you-" He rasped, before panting and glancing away for a moment. "My room?" Dinah finished, and Greaseball nodded dumbly.
Dinah licked her lips, before patting Greaseball’s chest plate to motion for him to get off of her. Greaseball pulled off of her not a moment later, before letting her grab his hand. Dinah giggled softly before pecking his lips.
Dinah and Greaseball’s limbs tangled each other as they bumped in the door of the bedroom.
Dinah panted, letting out soft squeaky moans as she fumbled with the doorknob, and Greaseball was peppering kisses along her neck, and as she managed to open the door, they both fumbled and fell onto the cot. Greaseball’s hips ground into the dining car’s, muttering groans as she arched and went to fumble her hands towards his lower back. Their bodies ground against one another like desperate little animals.
Dinah could feel her valve begin to leak lubricant, tripling down her thighs through her crotch plate and staining Greaseball’s org in the process. Greaseball huffed, pulling away and stopping for a moment. He could feel his engine purr louder, and he licked his lips as he gulped silently. "Are you..-" He huffed, pulling away to sit on the bed, slightly further away from her. "You sure?" He pointed between the both of them.
Dinah rolled her eyes, before sighing dramatically. "Trust me sugar." She cooed, crawling closer to him and grinning. "Iv’e wanted this for.." She trailed off, and fluttered her eyes playfully. "For a while." Greaseball nodded slowly, before letting the dining car crawl on his lap. Dinah hummed, biting her lip as he tried to grin. "Oh yeah?" He teased, adjusting and softly laying her down on the bed. His thumbs rubbing circles long her waist.
The dining car nodded sheepishly, shivering at the sensation. "I’ve been wondering.." She started, her face flushing darker. "If you really wanna do it?" She murmured. Greaseball blinked, before letting out a soft cackle and kissing her with as much passion as he could. "Starlight, Dinah." He breathed out, the biggest grin on his face. The dining car in question giggled lightly, as he kissed her again.
"I was waitin’ for you to ask." He snickered, before beginning to his down from her mouth to her chin, and down towards her neck. Dinah’s eyes fluttered lightly. "Is that a yes?" She breathed out. Greaseball chuckled again, before stopping at her skirt and nodding. "Hell. Fuckin’. Yeah." He grinned.
Alright. Okay. Dinah totally wasn’t freaking out right now.
Dinah grinned, and slowly slid her hands down to her skirt. "You want it?" She raised a brow playfully. Greaseball’s grin was almost catlike as he nodded, and Dinah let out a soft snicker. The dining car’s core had begun to beat faster as she slowly lifted her hands to unclip her skirt, and let it unfurl onto the bed. After she was done she spread her thighs open, rubbing her crotch plate with her hand. Licking her lips slowly.
Greaseball watched, his eyes wide as she slowly went to unlatch it, then she bit her lip as she slid the crotch piece away and wiggled her hips.
Starlight. Express.
Greaseball couldn’t have seen a more perfect valve before.
The whole thing, Greaseball couldn’t stop staring. Dinah’s valve, to his absolute delight, had almost the same color as her plating. Blue and white. Her linings were patterned in a way that her valve was practically glowing, and Dinah slid her trembling hand over to spread the lips. And now, Greaseball could see it all.
"S’all for you darlin’.." She panted, licking her bottom lip before grinning softly.
Greaseball bit back a low growl deep in his throat, but his engine was throughly betraying him. "Damn Dinah.." He rasped, sliding his hands down to hold her thighs, tracing those little patterns on them. He was thinking, thinking way too hard about what he wanted to do right now, but he couldn’t even word them properly. His usual demeanor was now gone, and he felt so vulnerable.
"You mind?" He tried to ask confidently. Dinah shook her head slowly, her face so red she might start to overheat. Greaseball’s grip tightened lightly as he leaned in close, slowly glancing up at her through his lashes before taking a long lick along the outing out her valve. Dinah’s legs trembled, and her bsck arched as a deep moan escaped from the depths of her throat. This was better than anything she had ever felt, and it was only a lick.
Greaseball hummed, deep in his throat as he slowly began to lap at his pussy, long and making sure to moan softly after each lick. It made Dinah’s valve wetter, and she groaned as he lifted her hips up more, and slowly swirled his tongue along the nub. Sucking it slowly and groaning as Dinah’s thighs trembled even more. He closed his eyes and went back to lapping at her valve. He loved the way she tasted, so so good, it made his spike harden as he listened to his dining cars whimpers and moans.
He had thought about leaving her high and dry for a moment. Just a moment. To watch her valve pulse at the sight of him, but he threw that thought away as he tasted more of her, the lubricant swirling in his mouth made him intoxicated on her only, and he panted as he licked his lips to pull away for a moment, before going back in and slowly sliding his tongue inside her. Dinah let out a surprised squeal, her eyes widened for a moment before her hand went to grip his hair. Tugging at it lightly.
Greaseball must be a natural at this. Dinah thought she’d seen it all with him, but apparently she didn’t see the side where he knew how to explore her body like this. It was honestly surprising, but also, not exactly. She had known about his endeavors before they had gotten together, and she was just the new coach at the yard. So, as she moaned his name like a mantra, and pulled at his hair tightly, she thought this was the best way her date could’ve ended.
As Greaseball lapped faster, so did Dinah’s moans get louder, breathier, and all the more squeaky. She thought her body might’ve overheated at this point, as he face had never been so red, but as Greaseball moaned at sucked, her eyes rolled back as she let out a loud squeal, and she came the hardest she ever had.
Dinah whined, pushing his head closer as he panted. Lapping and swallowing up all the juices she had produced. Greaseball, didn’t mind it, not at all, instead, he felt like his spike was about to burst from the seams, and he panted as she pulled her hand away, almost like it burned her. Greaseball glanced up at her, and she still looked as beautiful as ever, well, even more now that she was in this state.
Her cheeks burned bright, her hair was messed about in all the right places, and that cute little waitress tiara that was always situated on her head was practically about to fall, hanging on the side of her head. Greaseball couldn’t laugh, he really couldn’t. It was the hottest thing he’d ever seen today. Greaseball sat up, wiping his mouth before Dinah stared up at him. "You okay with uh.." He stared, but Dinah was already on it, kissing his passionately before pulling away and nodding like mad.
Greaseball gulped, before he nodded and crawled away from her, fumbling with his crotch plate before unlatching it and throwing it somewhere in the room.
It looks like they’ll worry about that later.
Dinah couldn’t have been more wet. And she couldn’t help but stare at his spike. Greaseball was…definitely large. In both places. He was thick, the lining on the sides of his cock glowed gold, slowly going in and out as the tip of his spike dropped sweet sweet oil. Slowly sliding down the shaft. Dinah bit her lip, and her eyes dropped. She pull have wanted to give it as taste, but that familiar ache had plagued her again, and she wanted that thickness inside her right now.
Greaseball was sheepish, or at least he looked the part. His cheek burned as he stared at Dinah eyeing his spike like it was dinner. He wouldn’t have minded if she wanted to taste it, every coach he’d been with wanted to, but Dinah looked back him, licker her lips, and pounced him.
Even though she wasn’t as strong, she definitely made the impression. Greaseball grunted, his eyes wide as Dinah kissed all over his face, before humming and giggling breathlessly. Greaseball felt Dinah roll her hips lightly against his spike, and he hissed for a moment. That moment, it had made Dinah want to feel it again, and so she slowly laid herself down, spread the lips of her valve and wiggled her hips.
"Darlin’, I’m fine with anythin’ at this point." She snorted, and Greaseball chuckled dryly. She waved him closer and as Greaseball lined himself up with her valve, she raised her hands to grip his shoulder boxes, tensing lightly as he rubbed his spike along her valve. Greaseball could tell her hesitance, and he leaned down to kiss her softly before slowly sliding one inch inside her.
Both grunts and moans filled the room, and Dinah whimpered lightly before letting her head fall back. The stretch was definitely there, filling her in ways she’d never thought was possible. Tears stung in her eyes, but she panted and pulled the diesel closer, letting Greaseball stop to let her get used to him. Greaseball inched closer and pulled her into a light hug, kissing her cheek to stop the tears that fell from her eye.
"You can.." Dinah grunted softly, and after a moment later nodded towards him. "You can move." She murmured. Greaseball closed his eyes, before nodding and kissing her softly. The heat of her valve, and the tightness, he could roll his hips, and the slickness of her lubricant squished lightly. The champion sighed, before moving in deeper, then pulling out slow and moving in deep. Dinah groaned, arching her back as she lifted her legs slightly to wrap them over his waist.
Greaseball nuzzled into her neck, softly kissing and sucking it as he slowly thrusted hips. Rolling them lightly after going in deeper. His thrusts, were the best part about this. Dinah felt the ache turn into a need, a burning need that had wanted to burst out and control her, but she didn’t want that, not yet. Dinah wanted to feel everything, every little burn, every slip and every feeling the both of the, would feel. It was intoxicating, a feeling she would never want to let go.
The dining car could feel her hips slowly undulating against his, and every roll made her thighs tremble, and a long whine would make itself present. She loved it, and she could tell from Greaseball’s face, the way he groaned, his muscles trembling at every thrust, and his heavy panting. Starlight, Dinah wanted to do this again. Greaseball grunted for a moment, before kissing over to her chin and kissing her gently, his tongue slipped in, and she took it on, swirling her tongue with his as her hands went down to her lower back.
Greaseball’s heat radiated from his engine, loud purrs escaping as he groaned into her mouth, his thrusts only going slightly faster. Dinah moaned louder, mostly moaning the diesel’s name before whining and pulling off the kiss to hide towards his neck. Trailing soft kisses, and softly biting into his neck as he dug all the way in. Something that ,she her whole body tremble with pleasure. Greaseball gasped, his eyes widening before he let out a low whimper. His hips stuttered the moment he went to thrust into her again, and he let out a wheezing chuckle as she sucked on it.
Dinah pulled off of it, letting out a soft pant before grinding up against his thrusts and giggling breathlessly. Greaseball never sped up, only sliding into her with medium paced thrusts, and the stretch making him gape. It was pleasant, much better than any other coach. And as he rolled his hips again, Dinah huffed and moaned loud, cumming as her whole body trembled, like a leaf. Greaseball could feel it, he could feel all of it, and he bit his lip.
His trusts slowly becoming faster and sloppier as Dinah nodded towards him. Letting him continue before he groaned and let out a a sporadic moan that intertwined with a loud blasting whistle. Dinah jolted slightly, before giggling breathlessly as he panted and flopped on top of her. His oil spurred deep inside her, and she moaned with content. After a minute, Dinah slowly trailed her hand through his hair, and Greaseball moaned lightly.
"Hey darlin’.." She cooed after another moment, licking her lips and grinning softly. Greaseball slowly tilted his head to look up at her through her breastplate. "Hi, hun." He giggled. Dinah kissed her forehead, and Greaseball sighed.
They stayed like this, for a few moments more, before Greaseball slowly retracted his spike from her puffed valve. Dinah trembled lightly, and Greaseball slowly adjusted onto his knees. Greaseball bit his lip, as Dinah sighed, sitting up and glancing up at him through her lashes. "You want a snack?" The dining car murmured, shrugging sheepishly before put her leg over the other. Greaseball blinked, before shrugging and crawling over to her. "I think I already had enough." He teased.
Dinah flushed, and pushed him away with her elbow. "You little!-" She snorted, not taking it very seriously before giggling and shaking her head. Greaseball laughed, maneuvering to hold her into a hug that made that them both fall onto the bed with Dinah smacking his chestplate with playful insults. Greaseball growled, and switched her onto him with a smug grin. Dinah pouted playfully.
"Now." He tutted, kissing her and chuckling at her fake fuming. "Is my dining car hungry?" Dinah paused, before looking away. Her face flushing slightly. She was. She was definitely hungry right now. "Kinda." She giggled. Greaseball nodded, and kissed her again. "Then, I’ll get somethin’." He promised, before rolling over so they were facing each other on their sides. Greaseball wasn’t denying her of a snack, no. He was just..sleepy. "Right after..uh.." He trailed off, and Dinah glanced at him.
"Right after this."
Greaseball kissed her softly, before pulling her into a hug, and going right to sleep.
Dinah blinked, before shaking her head and grinning. She could’ve rolled her eyes, but she just sighed, and then giggled.
Stupid Greaseball, and his stupidly cute sleeping face. Starlight, she couldn’t be mad at him.
