Weetamo whimpered quietly as the door shut behind Nix - and Nix took a moment to survey where she would work. It wasn't exactly auspicious: The saloon's second story was narrow and creaky, the floor thin and the sound of piano playing and conversation drifted up across the carpeting that had been thrown down higgledy piggledy by some saloon girl during her rounds. The window was glassless and the only light came from a bare, cheap electrical bulb that was threaded to a copper wire that itself vanished into the darkness of the ceiling. Considering the rest of Maryfort, Nix supposed they had an atomic turbine buried somewhere in their small settlement, likely near their chapel. It provided enough power for electricity and maybe some emergency heat during winters, but likely hadn't been tended to in years.
She put the thought out of it out of her mind as she closed the door, latched it, then stepped up behind Weetamo. The slender green train was looking out the window with clear nervousness, her hands touching together over her belly. "I-I've never been serviced by a technician before. Well, okay, I was, but I wasn't Weetamo at the time. See, I was a passenger train, back in the day, but then they had to change the cars, and, well..."
Nix knew quite well. A train wasn't just the engine - even if people had thought so for ages. It was the engine and all the cars attached to it, as well as the linkages, even some of the track that it ran along. Even the brakes. All of it combined to create the spirit of the train. But train cars could be, and often were, changed. Nix had heard it compared to an ancient riddle about the Spirit of Theseus - if every part of the Greek hero's ship had been replaced, part by part, then would her soul be the same by the end of it?
Well, it depended on the parts replaced.
Put a new set of antiaircraft guns on an airship in the place of her old flare batteries, she might get more aggressive and less flighty - over time, as the change seeped into her soul. For trains, it could be quite traumatic to remove every car at once then hitch new ones, so trains changed their outlines slowly, cautiously. Nix didn't blame her for being so disconcerted thinking about it, and she didn't want her to keep thinking about it. Not now. Not in a situation that was meant to be tender.
Gentle.
She stepped up behind Weetamo's back, her arm snaking around her belly. She stroked the sleekness of Weetamo's stomach, feeling the faint seams that let her turn and bend her slender body. Her fingers stroked down and she found the belly button of the train-girl, teasing it with the tip of her middle finger. Her voice was soft. "It's okay, Weetamo...your tribe is never going to let that happen again." She kissed her neck. "And this isn't like changing a car."
"Okay..." Weetamo whispered. She leaned into Nix, relaxing more and more by the moment. "What is it like?"
"I'll show you," Nix said, grinning. She gently led Weetamo to the narrow, thin bed that she had been given. She drew her down and Weetamo sat on it, her eyes wide as Nix sat next to her. She smiled and looked into Weetamo's eyes, her voice soft. "We start off with what makes you comfortable." Her fingers stroked along Weetamo's thighs. "Do you like that?"
The train nodded, blushing furiously. Thin streams of steam were sneaking out of her cheeks - venting into the air and coiling up towards the ceiling.
"All right," Nix said, quietly. "You have such beautiful lines, you know. And you've served so well. You can run on track that's barely even there." Her fingers slid up and down, up and down that muscular green thigh. She leaned in, kissing a spot on Weetamo's neck where the paint had chipped, old damage reflected on her throat. "You're a good train. Good little steam burner." She nuzzled against her, then kissed along her throat, up to her jaw, to her ear. Her voice was soft. "You're so hot and wet."
"Y-Yeah," Weetamo whispered.
"And I saw your engine - you've got such a clever little boiler set up. You'll never rupture, not with that design and good maintenance. That's so impressive."
"R-Really?" Weetamo asked, sounding shocked. "I-I always thought it was so...outdated!"
"It's gorgeous," Nix said, grinning at her. She slid her palm up her thigh, then inwards, teasing her fingers against the dampening folds of Weetamo's rubbery cunt. She didn't quite touch her, but she didn't quite
not
touch her. She left Weetamo tingling between contact and release and Weetamo drew in a sharp gas, her soft
chugga-chugga-chugga
heartbeat audible through her chest. Her breasts heaved as she arched her back slightly.
"N-Nix!" she moaned, biting her lower lip to silence herself.
"Mmm, let it out. We can't let you get too...under pressure," Nix whispered.
"Oh...ohhhh!" Weetamo whispered as Nix's fingers traced the outline of her sex, teasing her clit as she swept them up and around. Her lips parted and a thin stream of steam ticked along the roof of her mouth, past her nose, curling around her hair. Nix leaned forward, catching the last tiny spurt of warm, moist breath in Weetamo's mouth. Her tongue and the spirit's tongue pressed together, playing one against one another as Weetamo's thighs spread, bumping one against Nix's knees. Her hands bunched, grabbing onto the blankets as the bed creaked. Nix drew back, letting a thin ring of steam escape from Weetamo's mouth.
"Want more?" she whispered, kissing her ear, nibbling the lobe.
"Y-Yes! Yes!" Weetamo gasped. "I-I've never felt like this before. I-"
Nix pressed a finger against the folds of Weetamo's cunt and thrust in. She felt virgin tight, her lips enfolding Nix's finger with vice-eager heat. A blazing warmth flooded around Nix's fingertip, and as she pushed her finger in to the knuckle, Weetamo let out a mewling moan of purest pleasure, her hips bucking as she gasped and whimpered. "Oh my god, oh my god!" she gasped. "M-More, please! I...I..." she quivered and grunted low in her throat as Nix crooked her finger up. She found her G-spot, and through the trembling quiver that rocked through the train, Nix could feel every nut and bolt on her body going limp at once.
"Nix!" She moaned.
Nix grinned.
Then she added a second finger, leaned down, and found the tip of one of Weetamo's deliciously perky breasts. She sucked that bright green nipple into her mouth, teasing her with her teeth as her thumb reached up, rubbing Weetamo's clit, her fingers thrusting faster. She had to get past this part - if she let her tingle and hang too long, she genuinely might explode. And not in the
fun
was, precisely. The last thing that Nix wanted was to take Weetamo's engine out with a boiler explosion.
So, she finger-fucked her roughly, the knuckles of her finger
plapping
loudly and lewdly against her metal thighs. Weetamo gasped and moaned, her back arching as she screamed in bliss, her voice causing a momentary pause in the piano playing from downstairs - but as she bucked her hips and squirted around Nix's fingers, Nix heard the unsteady opening of
Yankee Doodle Dandy
resuming from downstairs - the first few notes hesitating between each tone, like the pianist was looking over his shoulder.
Weetamo drew in deep lungfuls as black smoke roiled from her back, smelling of warmth and lust. Her eyes were half closed and she groaned as Nix drew her fingers from her cunt, licking her glowing juices off her self. "W-Whoa..." she whispered.
"Feel how every nut and bolt on you is tight and true now?" she asked.
"Y-Yeah!" Weetamo said, her eyes widening. She arched her back again - to stretch. She heard something
PING
inside of her and her palm rubbed the small of her back. She let out a shy giggle. "T-There had been a bolt in there that was out of true a-and...I...I knew it needed to get removed, but I was worried if I asked, they'd just strip the threading out, so, I just kept quiet and now it's straight on and it feels so good! I feel like I could run across the Atlantic!" She giggled. "I-If there were tracks on the Atlantic, I mean. N-Not that there are, I know there isn't!" She added, hurriedly.
Nix, grinning slightly, licked her fingers clean. "I know," she said, her voice amused. "But that's just the easy part."
"Mew?" Weetamo asked.
"We still have your actual boiler to get running smooth - and your brake cables, and any rust."
"Oh!" Weetamo blinked. Then, her cheeks darkening, she stammered. "How, um, how do we, um, do, we...do..." She made a vague gesture, her palm flipping and over end. "Do...do that?"
Nix grinned. "Lets do rust first." She twirled her finger. "On your belly."
"Okay!" Weetamo started to turn to the right - realized this would slam her legs into the wall, blushed, then turned to her left, rolling onto her side, then her belly. As she laid there, she watched Nix stand and begin to strip, revealing her own slender body, her high breasts, her sopping wet cunt. "How do we fix the rust?" she asked as Nix tugged the strap up around her thighs. Her cock thrust into the air and she felt the strange sense that it was truly a cock - not just a device of leather and plastic. She grinned and took the base of the cock in her hand, lifting it up so that Weetamo could see the length, the girth. Then she picked up her bottle of lube from her belt pouch (no technician would leave their home without it.)
A thin stream of lubrication started to soak up the false cock.
"...what do you...how do you fix the rust with that?" Weetamo asked, her eyes widening more and more.
"Well, rust represents waste products and unfortunate buildups," Nix said, walking around behind the belly-sprawled spirit. Her hands cupped Weetamo's truly delicious, heavy ass - she did have quite a hefty caboose, after all - and her lube slick thumbs spread her asscheeks, revealing her pert, cute little asshole. Nix grinned, wickedly. "So, we just need to apply friction to a...symbolically useful area."
