Alright it's fanfic time (Theres valveplug I promise) I didn't realize how long it would get. It's kinda slow burn, holy shit I didnt know I could write this much
One day, Shouki was at a shop in Iacon looking at a bunch of strange inventions when he came across a mass shifting enhancer. Being a bot who majorly utilizes mass shifting for his alt mode, he was rather intrigued. When he asked the shopkeeper, it was explained to be able to make you able to mass shift in robot mode. Shouki, having his own sweet little human, was rather interested. Perhaps he could finally give her a proper kiss, or maybe a hug without worrying about killing her.
He happily bought the product, and tried it at home. He adjusted himself to a human height, amazed by how different JUST his own room looked. After exploring the place he's known his whole life from a new perspective, he went back to his normal form and read the box. Glad to find out that it lasts for as long as he has it activated, he IMMEDIATELY went to visit his human.
As soon as he arrived at the house of his precious human, he activated the device and waited by the door. As soon as she opened the door, she took a second to process what was in front of her: Shouki, who'd supposed to be a giant robot that turns into a bullet train locomotive, casually standing on her porch, at a not-giant-robot size, gently smiling at her.
After a good five minutes of staring and wondering, she decided to speak, her voice light and slightly confused.
"Shouki? Is.... is that you?" She asked with a confused expression.
Slowly nodding his helm, he confirmed "Yes, it's me."
With only a few seconds of pause, he was immediately tackled into a hug, but didn't fall over. He gladly hugged her in return, finally feeling her warm, soft form against more than just a tiny part of his frame. In a cute display, he spun her around as she clung to him before letting her put her feet back down.
"Wait... so... this means you can come inside!" She nearly screams in excitement, grabbing his now not so big servo and leading him inside her house, closing the door behind them both.
Noticing a bit of dirt on her hand after pulling him inside, she quickly realized that he probably needs a bath.
"Hey, hot bot? How often do you clean yourself?" She asked, trying to be as polite as possible
"Uh... well whenever I get visibly dirty or my paint starts to dull... why?" He asked with a tilt of his helm, and a bit of confusion.
"Well then.... let me give you a human style bath, my love."
"A what? Well, alright then!"
He happily followed her as she pulled him into her bathroom and turned on the shower, shoving him in.
"Is it warm enough? You can change the temperature with this" she says while pointing to a handle on the wall. "Turn it to the right for hot, and to the left for cold"
She watched as he turned the handle in curiosity, finding a temperature he liked. As she went off and grabbed a sponge, she decided that maybe human body wash wouldn't be the best for his metal body, and after telling him to stay in the shower as she left, she got some dish soap and brought it to the bathroom.
"Alright, you ready to be scrubbed clean the way we do it?" She said as she walked in, putting a large amount of dish soap on the sponge.
"I... uh... alright!" He responded, not used to this form of getting clean.
"I'm getting in with you, okay?" She told him while taking off her clothes
"Alright?" He said in a slightly confused tone, used to the solvent used in cybertronian cleaning rituals getting everything on it's own
As she stepped in with the sponge in hand, he looked over her fully exposed body, not used to being able to be this up close to her. How the water made her hair darker, the way it ran down her body, perfectly trailing down her chest, down her body, into the part he... wait, he stopped his train of though when he realized he was staring, his face flushing a light tint of blue.
With a giggle and a coy smile, she teased him
"Hello? Earth to Shouki, come in Shouki!"
Looking off to the side in embarrassment, the gentle glow of his optics brightened ever so slightly as he muttered out an apology with a slight bow of his helm.
"It's alright, you're supposed to like what you see if I'm your girlfriend, right?" She said, teasing him. He was doing his best to not let his cooling fans kick in from a mix of embarrassment, and internal heat from staring at her. He nodded, and as he did, she stepped closer to him, looking up into his optics with a gentle smile.
"Alright, alright. Let's get you all nice and shiny clean!" She gave him a playful smile and reached the sponge up and onto the top of Shouki's helm, gently scrubbing as soap sudds ran down his helm, and some even into his face. Not used to this method of cleaning, the sudds felt rather tickley on his metal, and he forced himself to hold back a giggle from the feeling.
Slowly, she worked the sponge down his body, scrubbing every nook and cranny, until she got to his codpiece.
"Well, I've seen you use and clean what's behind these panels after use before." She teased with a wink. "Do you wanna scrub the panel or should I?"
Blushing with an awkward chuckle at her comment, he contemplated for a second, until finally coming to a decision
"Well, you're probably better at this method of cleaning than me..." he said as his blush grew slightly more visible. With a smirk and a nod, she began gently scrubbing the panels covering his interface array, and he had to turn on his fans at that point, his venting becoming slightly heavier as he bit his lip in order to not make any... odd, let's say, noises. At this point, he was fighting to not open his panels right then and there as she scrubbed them, but he kept his self control and managed wait while she cleaned him
Getting past his panels and hip piece all together, she kept scrubbing down his legs and to the top of his pedes, at which point she told him to sit so she could scrub the bottom of his pedes.
As he sat down in the shower, water now running clear off his frame, she couldn't help but stop and admire her work, and how cute he was, in a new experience, his optics glowing with a mix of wonder and confusion. She couldn't get over how slightly silly this all felt, this -usually- giant robot, now sitting in her shower letting her clean him.
Getting back to cleaning him, she had to work the hardest on the bottom of his pedes, scrubbing dirt and... whatever dust was on Cybertron out of seams and odd panels. Once all the soap was rinsed off of him, she wrung out the sponge and put it off to the side.
"How do you feel? Bet it feels nice to be this clean, right?"
Shouki looked over himself, paint looking brighter than ever, and looking extremely shiny, partially from the water running over him
"I... I look like I was just constructed!"
With a giggle at his slightly bewildered and wonder filled statement, she decides to ask him another question as she quickly cleans her own body, soap running down her and highlighting her features. She was looking more enticing than before, with all the soap running down her, in Shouki's opinion.
"So, now that you're all clean, wanna have a bath?" She asks him as she rinses the soap from her hair and body
His only response is a fervent nod once she's looking at him. Flipping a switch, the water goes from the shower head to the spigot. As she gets the drain plug and puts it in place, she slightly arches her back and sticks out her ass and exposed parts, as a tease for her mechanical boyfriend.
The teasing worked, and as warm water started filling the tub, Shouki blushed, his thoughts now wandering into a more intimate territory. Once she stopped the water, she sat next so Shouki and stared lovingly at him.
After slight hesitation, he let her lean against him, her back against him, feeling the full warmth of her soft skin against his metal. Gently, as if not to break her, he lightly grabbed her chin and tilted her head so she was looking over her shoulder at him. Slowly, he moved so that he could place a kiss on her cheek, then trailed kissed from her cheek to her mouth, savoring in the fact that he could finally just... just kiss her.
As he reached her lips, he hesitated. Would she be okay with how his metal lips are? Would she find his metal teeth and soft tongue to be an odd combination? The only way to know was to find out.
As gentle as a feather, he put his lips to hers, and shut his optics as she shut her eyes. The softer, special metal of his lips and face feeling nice against her plush, soft, lips. After a few seconds, she disconnected due to need for air, and looked at her lover, a gorgeous shade of light blue dusting his cheeks as he stared at her with half lidded optics and a gentle smile. She mirrored his expression, and leaned in for more
As their lips pressed against each other, the kiss slowly became more heated as both of their bodies pressed against each other, unsure if the heat was from the warm water they were in, or each other. At some point, Shouki wound up leaning on the back of the tub, while his girlfriend was lying on top of him, slightly floating in the bathwater.
With a slight groan escaping his vocalizer, Shouki nipped at her bottom lip, asking to deepen the kiss more. With eager compliance, she opened her mouth more into the kiss, letting his oddly soft tongue explore her mouth, somewhat having a wrestling match with hers, filled with fire and passion.
As they continued to kiss, muffled moans and quivery breaths along with the slosh of bathwater were the only sounds in the room, as hand and servo started to wander.
Finally able to grab and touch specific parts of her rather than hold her entire being in one servo, the first thing he grabbed was the soft mounds of her chest, slightly floating, and just big enough to fill his servo. She moaned into the kiss, her voice muffled by Shouki's lips.
Slowly, she pulls out of the heated kiss and leans back, straddling his hips, to give him better access to her chest. She puffs out her chest, trying to make a show of it with slight movement and everything. Half lidded eyes meet slightly wide optics, those softly glowing optics watching as his servos squish and play with her tits, finding the soft, fully flesh sensation to be overwhelming.
At some point which neither of them remember, both of Shouki's interface panels opened up in the water, leaving a pink tinted trail of pre-transfluid and valve slick swirling in the water, and his spike pressing against his girlfriend's soft ass, her own slick mixing into the water as well.
Realizing his spike was right under her, she put her hands on his chassis for support, and slowly started to drag her pussy up and down the length of his spike, causing him to kick his cooling fans into high gear and blush to the point that his faceplate was nearly glowing. With a shivery moan, he moved his servos from her chest to her rear, gently grabbing servo-fulls of the soft flesh as she moved along his length.
After both of them letting out a few moans and shaky breathing/venting from the movement, he looked at her in the eyes, with half lidded optics, and with a shaky voice, spoke.
"Please... ah..... please let me put it in... I.. I want to feel, you, make you feel good, frag you and...!?" Shouki was shushed with a kiss, his desperate begging driving his girl nearly over the edge, and she didn't want that just yet.
"Of course, as you wish my love." She said with a wonton tone and a sultry grin, slowly lifting her hips out of the water and positioning them over his spike, giving a teasing wiggle before lowering herself onto him at an agonizingly slow pace.
Shouki's optics were glued onto where her pussy swallowed his spike, letting out a moan from both how good she felt, and how hot it looked as she slowly sheathed him. Once his spike was fully inside her, she hissed and groaned as it left a slight bulge in her lower belly. As she looked down at the spot where his tip was obvious under her flesh, she brought a hand to the area to touch it, having never put something so big inside of her in her life.
With an involuntary snap of his hips, Shouki thrusted into her, making water splash out from the tub.
"Careful hot bot, don't wanna get the floor wet~" she said with a small giggle as she slowly began to move, careful not to splash too much water.
They began to move in sync, slowly watching as his spike went in and out of her, Shouki was a blushing, moaning mess with loud cooling fans running. His girlfriend was riding him so well. Her moans and praises were like music to his audials.
Resetting his vocalizer, he tried to speak "A-ah~ you're riding me so well, my love~" he praised, struggling to get his words out through moans and static.
"And you're being.. agh~ such a good mech, so so good." She returned his praise as she moved up and down at a slightly faster pace on his spike, water splashing around them no longer caring about the mess they'd have to clean up later.
His servos gripped her hips, feeling both soft flesh and hard bone under his grip. Helping her move along his spike even faster, he was sure that he would leave bruises on her, but he wasn't complaining if she wasn't.
Suction from the water enhancing the experience, he couldn't get enough of her expression, her eyes rolling up from pleasure as her mouth hung open. At just glancing at her face, he felt himself come close to overload, and she could also feel the knot building in her body, threatening to snap.
"Ahh~ ah, sweetspark, I.. I think....!" Before he could get his words out of his vocalizer, his fluorescent pink seed was spilled directly into her womb, and as it did, she felt herself snap and spasmed around him, her own juices coating his spike. As they both rode out their highs, lightly glowing transfluid spiraled in the now not-so-clear water along with a thick, clear substance.
As she collapsed on him, his spike still buried in her, Shouki gently held her, her head resting on his chassis above water, her eyes shut as she recovers. Shouki himself was having a hard time staying conscious. Gently moving into a position where he knew she would be safe, and manually locking his joints, he rebooted himself.
As his optics opened again, he saw his beautiful girlfriend smiling up at him from where she lay on his chest.
"So, was that better than some toy, or device simulating me?"
Through a slightly staticky vocalizer, he responded. "So, so much better."
Now that he was safely back online, he unlocked his joints and she got off of him and emptied the now tainted bathwater, turning on the shower to quickly rinse them both off. As they step out, she grabs two towels and hands him one, along with a quick kiss. As they dry off, they slowly realize how much water got on the floor, and they look at each other, share a laugh and start to clean it up.
TLDR: Local train gets a bath and gets ridden in the best way he could imagine
