Oil Spill

Summary:

Billy heard rumors of this "cold mechanic witch" who could possibly help him get some oil for his system. Not taking the warnings of his peers seriously, he finds himself in a rather... vulnerable position.

Notes:

PLEASE GO EASY ON ME IT'S BEEN FOREVER SINCE I WROTE A FANFIC ;v; Billy Kid/Grace Howard enjoyers rise...

(See the end of the work for more notes.)

Work Text:

“Okay… it should be around- aha! Found it!” Billy exclaimed, happily striding towards the Brant Street construction site, also known as the home of Belobog Heavy Industries. He walked up to a group of onsite engineers off to the side of the entrance.

 

“Hello! A little Bangboo told me that you guys have a top-tier engineer who could possibly help me with something?” The engineers immediately stopped what they were doing, giving cautious glances at each other as they all inspected Billy from head to toe. One of them coughed to break the awkward silence, a strained grin plastered on his face.

“W-We sure do, she’s the best of the best!” he said, leaning himself closer to Billy as his voice dropped to a whisper. “But um… fair warning, she can be a bit… uh… much?”

Billy cocked his head to the side in confusion, a sense of deja vu occurring.

That’s interesting, the Manager said the same thing before giving me the address to this place-

“KAIDOU! Just what do you think you’re doing?!” A strong voice could be heard across the construction site, causing Kaidou to freeze in place and sweat profusely. The group of engineers who were chatting with him not too long ago now nowhere to be seen as a woman donning red goggles quickly approached him and Billy. Her red eyes were fierce, almost like she was burning holes into the poor engineer.

“I-I’m sorry, Grace! I didn’t mean to-”

“What do you think you’re doing… having this hunk of metal all to yourself?” Grace quickly rushed past Kaidou like he didn’t even exist, making a beeline to get a closer look at Billy. Her face lit up with excitement, like a kid in a candy store, making it hard to believe this was the same person who shouted with such authority earlier. She got so close so suddenly Billy didn’t know how to react, feeling the heat from his coils rising as she continued to inspect him at close proximity.

“Such a solid yet lightweight body for an android! And it looks like you’re a pretty strong one at that, the scuffs on your plating is a shame to see but given how well-put together you are, it seems really durable! I wonder what kind of metal was used for your body… Oh such intricate detailing too! Now where did a handsome piece of work like you come from? Can I examine you more? Do you mind if I take off your-”

Ahem. Grace, keep talking like that and I’m afraid the poor guy is going to explode from how much he’s overheating right now.” Kaidou interrupted, redirecting her attention to a clearly overwhelmed Billy. She wasn’t even touching him yet every movement she made around him with such intense staring made him feel flustered beyond belief.

 

Is… is this what they were talking about?!

 

“Ah, that explains why it felt so much warmer out here! Sorry about that, I got carried away again.” Grace spoke, her professionalism setting in again as her expression became more neutral. Kaidou let out a sigh.

“He said he needed help from you, though didn’t get enough time to say what it was before you got here.” Kaidou looked over at Billy, expecting him to explain himself. But all the android could muster at the moment were mumbles and stutters, trying his best to cool down.

“I… yeah… oil… need…” Billy breathed, barely being able to form complete sentences as he continued muttering like a tangled mess. Grace’s eyes lit up once more, quickly grabbing Billy’s hand, abruptly restarting his cooling process without noticing.

“An oil change? Well why didn’t you say so, I would love nothing more than to help! Here, I’ll take you back to my station and I can get that fixed up for you right away!” Without a moment’s hesitation, Grace started dragging Billy back with her to a storage unit, sitting him down before rummaging through the supply bins.

 

“Oil… oil… where did I put it…” she mumbled to herself, thoroughly looking in every nook and cranny. Billy, finally coming back to reality, darted his optics around the new environment he was placed in. He was sitting on top of a sturdy cardboard box, the only light in the unit coming from the half opened windows on each side. He heard Grace exclaim joyfully as she picked up a fresh can of oil, walking over to him with a rather devious grin on her face.

“Thank you! I’ll make this quick, no need to worry-” Before Billy could finish speaking, Grace swatted his hand, holding the can further away from him.

“I never said you could use our oil for free, let alone apply it by yourself,” she said, leaning in closer to Billy. She set the oil off to the side where Billy couldn’t reach, her hands gently prying his jacket off. “Let me take care of it for you, okay sweetie?”

Billy didn’t even get time to respond before his jacket was thrown off to the side, Grace’s hands skillfully feeling around his arms and sides. He could feel his fans go into overdrive as she glided her fingers across his backside. She was practically on top of him, her dominance of the situation overwhelming Billy once again.

“You’re a work of art, y’know that?” she whispered, followed by a light chuckle. “I’ll make sure to be careful with you.”

She made quick work of him, fingers slicked with oil and carefully lubricating the joints around his shoulders. Billy shuddered under her, the whirring of his system growing louder as he struggled to breathe air he didn’t even know he needed. He was practically frozen in place, letting the engineer take total control, feeling her chest press against his as she continued down his back once more. He twitched involuntarily at the cool oil sliding down his wiring, Grace laughing at the reaction.

“Sensitive, are we, sweetheart?” she teased. “I wanna take my time inspecting every part of you, so try sitting still for me.” Billy was practically malfunctioning at this point, barely able to get his own thoughts together. She truly was an expert with the way her hands moved with ease around his gears and bearings, making sure to grab enough oil to properly and thoroughly lubricate everything she touched. 

 

“W-W-Wait, hold on… please…” he pleaded, Grace pausing her actions and removing her hands completely off the android. Billy finally had time to collect himself, even if just for a second, surprised that he was even able to speak just now.

“Sorry, I wasn’t hurting you was I? I can get pretty excited when it comes to working with machinery, especially amazing ones like yourself…” Grace’s voice trailed off, her eyes laying on the components of Billy’s entire torso. She started thinking about the inner workings of cables and coils he had going on in there, licking her lips at the thought of it.

“N-No, not at all ma’am! You… you do a very good job at… h-handling me…” Billy stammered, darting his attention everywhere but Grace’s hungry expression, her gaze alone making him feel like he was being eaten up. 

If Billy had the ability to blush, he would be so red it matched his jacket. He calmed himself enough to shift into a less stifling position, accidentally shifting Grace to sit on top of one of his thighs. She suddenly gasped the moment she sat down, feeling how his entire body was physically vibrating from how hard his systems were running this entire time. A quiet moan managed to escape her lips as she tried readjusting herself, enjoying the new position a lot more than earlier.

“Is that so…” Grace swiftly continued right where she left off, causing Billy to shake in surprise. She wanted to savor every moment she had with this android, watching the way his body shook and twitched with just the touch of her hands. She started wondering how much she could really make him squirm, to see what other expressions she could get out of such a responsive piece of work like him. She had to stop herself from wanting to take him apart to truly see what she was working with as the thought of it alone was enough to make her aroused. This was truly one of her top highlights in her career.

 

Billy was in a more comfortable position now, sure, but it didn’t take away how embarrassed he felt. He had Nicole help him reach spots he couldn’t get himself while lubricating his system before, but never did he think this process could feel so… pleasurable. It didn’t help that Grace’s hand slowly made its way down his chest, the way he shuddered at her touch made her grin devilishly.

“You really are one of a kind…” she mumbled, taking her sweet time examining every inch of his body as she continued trailing her hand down. 

Her fingers playfully traced around his belt buckle, snapping it forward. A shock shot down Billy’s spine, the vibrating of his system intensifying against Grace even more. She was thrown off guard by this, promptly steadying herself by gripping Billy’s shoulders tightly while keeping the moan in her throat at bay. This sudden action also knocked the can of oil off the table, spilling all over them and splattering everywhere. There was a moment of silence between the two before Grace suddenly burst into laughter, taking off one of her gloves to wipe her eyes, beginning to tear up.

“Ah… well that was fun while it lasted,” she spoke calmly, hopping off Billy’s leg to quickly grab a couple rags to clean themselves up with. “I better go take care of this mess on my clothes… last time I tried washing oil-stained clothes in the machines, Sweet Pea got mad at me for nearly starting a fire.” 

Grace motioned towards the supply bin she originally grabbed the oil can from as she opened the door. “Feel free to grab another can on your way out, sweetie! Hopefully we can have more fun next time you need help oiling up?” she teased before walking out the storage unit, leaving a very dazed and flustered Billy behind.

 

What… What just happened??
