Revenant doesn’t think he’ll ever get used to how fucking big Pathfinder’s attachment is.
“Are you alright, love?”
“Fine,” Revenant forces out; his vocalizer makes it sounds like he’s speaking through gritted teeth. The wonders of programming. “Just– adjusting.”
“Take as long as you need.” Pathfinder’s hands rub Revenant’s sides and the leathery material covering his chassis, fingers dipping into his hip joints. Revenant holds very still, trying his hardest not to twitch and crush Pathfinder’s fingers, but the way the MRVN tugs his wires makes it damn near impossible.
“P-path, you should–” Pathfinder gets the hint and relocates his hands to the insides of Revenant’s thighs. Revenant starts to relax, then immediately tenses again as Pathfinder hooks his finger under a cable and pulls . “Ah–!”
“Was that good?”
How the fuck does he manage to sound so innocent and so fucking smug at the same time? “Fuck off,” Revenant mutters, wincing internally when his squirming makes Pathfinder’s cock shift inside him. Fuck, he’s barely halfway in…
Achingly gentle, Pathfinder’s fingers trace the edge of Revenant’s own mod, stroking the place where he's stretched obscenely wide around his cock. The light touch makes Revenant shiver, and Pathfinder lets out a blissful sigh. “You’re so beautiful, Revenant.”
Revenant’s cooling fans whirr louder as they fight to lower his rising core temperature. “Whatever,” he huffs, gingerly lifting his hips to push himself down on Pathfinder’s cock another centimeter or two. “You can move, just be care fu– !”
The overeager bot sinks in all at once, smooth and steady, bottoming out with a series of satisfied beeps. Revenant, on the other hand, arches up in a curve so deep it would break a skinsuit’s spine, crying out as he’s forced to stretch so far it almost hurts, like a rubber band about to snap. It’s so much , and Revenant can only pant and curse as his processor struggles to make sense of the shock and pleasure.
After what feels like an age of sweet agony, his tense frame finally relaxes and goes limp on the bed, legs loosening their death-grip around Pathfinder’s hips. He feels fuzzy, and warm, and when he onlines his optics again Pathfinder is just fucking– staring . “The fuck– haah, are you look– looking at?” he slurs out, looking hazily up at the MRVN as he waits for his systems to reset and his optics to focus again. The glint in Pathfinder’s optic and the wide-eyed blushing emoji on his screen make Revenant want to squirm.
“Did you just orgasm?”
Fuck . Well, this is humiliating. “That’s a stupid question–”
“Just from me putting it in?” Pathfinder presses insistently, and Revenant glares up at the ceiling in embarrassment.
“I’m sensitive , okay, it’s been a while since–”
“Can– c-can I keep going?”
The rough edge of static in his voice makes Revenant look up, just in time to see a cloud of steam rise from Pathfinder’s vents, screen rapidly alternating between various suggestive emojis and an error message. Oh, he’s shaking .
This isn’t a good idea, not with how sensitive Revenant is and how keyed-up Pathfinder seems. He really shouldn’t.
“Just– take it easy,” he says, shuddering at the way Pathfinder’s grip on his waist immediately tightens. The bot’s optic dilates; a pair of yellow praying hands appears on his screen beside– an eggplant. Christ.
“Thank you,” Pathfinder tells him, so sincerely it’s almost funny, then lifts his hips and thrusts in hard at an angle that would make his toes curl until they cramped if he still had them. It’s good , and kinda painful, and so fucking intense that Revenant is a little worried Pathfinder will blow right past ‘overload’ and end up completely restarting him. He’s not sure if his processor can handle this much stimulus– and this mod is new , dammit; Pathfinder was supposed to break it in , not break it.
The worst (or best) part is that Pathfinder is clearly holding back, shaking with the effort of restraining himself, and Revenant still can barely take it. If this is Path’s version of being gentle, Revenant’s a little scared of what him being rough would look like.
He reaches up to hold onto Pathfinder’s shoulder handles, letting his head fall back and his optics flicker offline as the MRVN rocks into him with a combination of aching tenderness and desperate, impatient need. Pathfinder isn’t programmed to imitate breathing like Revenant, so instead of panting he just beeps frantically as he buries himself in Revenant’s oversensitive attachment again and again, obviously reveling in the pleasure of being inside him while Revenant just tries not to fall apart.
“Feels– ah, good,” he gasps out, knowing how much Pathfinder likes to be praised. Sure enough, Pathfinder moans , as much as a vocalizer not built for that kind of noise will allow. His hands shift from Revenant’s hips to his thighs, hitching his legs up over his waist, making Revenant curse when his next overenthusiastic thrust hits him just, fucking perfect – “There, Path, there, right– ah! Easy , fuck, right the-there–”
Pathfinder eases up a little, thank fucking God, strokes slowing to a pace that doesn’t make Revenant worry that he’s going to be fucked into unconsciousness. “ Rev ,” Pathfinder whines, and Revenant leans up to bump their faces together in a clumsy kiss, loosening his grip on Pathfinder’s handles so he doesn’t end up tearing them off in the throes of passion.
“Good, Path,” he huffs, legs jerking as Pathfinder fucks him harder, fueled by the praise, “J-just, slower– slow down, if you– you keep going like that I’ll– fuck, I’m gonna–”
He doesn't let up for a second, moving like a– well, like a machine, the steady drag of his cock against Revenant’s synthetic nerve endings pushing him inexorably towards the edge. “Please,” Pathfinder moans; his screen rapidly flickers between increasingly vibrant shades of pink, and fuck, Revenant loves him, he fucking loves him, “Want y– I want you to.”
Revenant presses his forehead hard against Pathfinder’s optic and warns him, “Path, I’m gonna cum,” and Path fucking begs him,
“ Please .”
He’s never been able to tell him no.
He does his damndest to block out the sound of his own fritzed-out, pathetically trembling voice moaning Pathfinder’s name like a two cent whore as he cums for the second time the night, quivering legs pinched tight around his waist, claws screeching against the metal of Pathfinder’s back as he wrecks his paint job. Revenant presses his faceplate into Pathfinder’s shoulder and just feels : the weight and warmth of the MRVN on top of him, the aching stretch of his cock filling him, the force of his increasingly frantic thrusts as Pathfinder nears his own peak.
It's so much, he can't fucking think ; the last fragmented remnants of human instinct takes over as his arms lift up to drape over his shoulders, heads coming together with a dull, metallic clunk . He presses his false lips gently against the lens of Pathfinder’s optic and sighs, “Inside, baby,” and Pathfinder all but sobs as he cums.
Murmuring affectionate nonsense, Revenant keeps his legs locked around Pathfinder, holding him close as he rides out his orgasm with small, jerky rolls of his hips and even smaller noises, faint and sweet. They both groan as Pathfinder gingerly pulls out, his rapidly cooling lubricant dripping out after him.
They lay together for a while, listening to the noisy whirr of their cooling fans, Revenant’s heavy breathing, and Pathfinder’s tranquil beeps.
For once, Revenant is the one to interrupt the peaceful silence. “Has anyone ever told you that you’re too big?”
Pathfinder burrows his face a little deeper into Revenant’s shoulder, holds him a little closer. “A few.”
“Why the hell did you pick such a big one anyway?”
The MRVN beeps thoughtfully. “I thought that bigger would feel better for my partners. Now I know that isn’t true, but I like it too much to change it.”
Revenant snorts. “Proud of your weapon, huh?”
“I’ve made a lot of good memories with it.”
Revenant can’t help it: he laughs. Then Pathfinder looks up at him like a deer in the headlights, and that just makes him laugh harder.
By the time the fit of giggles passes, Pathfinder’s bright screen is covered in a veritable collage of heart emojis, its light bathing the two of them in a rosy pink glow. It makes Pathfinder look downright angelic, and Revenant needs to kiss him, to cup his face and hold him tighter and tighter until he isn’t sure where he ends and Path begins. So he does.
“Love you, tin can.”
Pathfinder fumbles for his hand, letting out a quiet hum when Revenant laces their fingers together, palm to palm. “I love you too, darling.”
