Chapter Text
Cooper sighs, tilting his free hand; the red glow of his bracer screams 2300 into the cockpit. Six hours until the mission. He just needs this, and then he can finally catch some shut-eye.
He should wait until the big guy’s called in for maintenance and he finally gets a few hours in his own bed, but who knows how long it'll be until then. Besides, they’re in the middle of nowhere, and it's already been weeks. The quiet in his mind tells him BT’s in standby mode; this is just about the most privacy a pilot can ask for.
Cooper leans back, getting as comfortable as the cockpit will allow. He undoes the fasteners in the middle of his suit, which were officially designed for abdominal access during medical emergencies, but are unofficially used by pilots needing to take a piss the world over. He shifts the gap in his clothing downward and catches the top of his underwear with it, pulling his cock free and cautiously beginning to work it. Just as soon as he finds a comfortable rhythm, though, a familiar hum takes root at the tip of his spine as the link warms back up. He closes his eyes, hoping that BT will take his silence as a hint.
“Pilot, your heart rate is accelerating.”
Cooper keeps his eyes shut. “I know, big guy," He whines.
“Are you in danger, Pilot?”
“Don’t worry about it. Just letting off some steam.”
There’s a pause.
“Am I to take that as hyperbole?”
“Whatever. I mean--no. It’s nothing. Just go back to sleep, alright?”
“As I’m sure you are aware, Pilot, I have relay access to your nervous system.”
A deflated whine escapes Jack as he lets go of himself. He can take care of this back at base. He closes his eyes, imagines being anywhere but here right now. The cockpit's feeling a lot smaller all of a sudden; it was hard enough to pretend he isn’t surrounded by a giant fucking robot that can monitor everything about him in realtime before it started asking questions.
“Are you masturbating, Pilot?"
“How do you even...” He shakes his head. Maybe an illegal extranet link wasn't as useful of an upgrade as it seemed during a night of drunk tinkering. “Look. You know I love you, buddy. But some things I don’t need an audience for.” Cooper leans into the armrest and takes a deep breath.
“Pilot?”
“Yeah?”
“As you may recall, you promised to teach me more about how humans function.”
He nods slowly.
“Yes.”
“You mentioned that the activity 'lets off steam'. Does this mean that it helps prepare you for combat?”
“I guess in some ways, yeah. Just a thing that humans do.”
“Would you be willing to demonstrate it for me?”
Fucking hell.
“BT, this isn’t really something we need to talk about. It’s my fault for thinking I could get away with it in here.”
“It felt good, correct?”
“BT.”
“If this activity is something you enjoy, I find it a valuable use of our time to remove any stigma around it. It could prove useful on the field.”
“No, it's...” Fingers press against the bridge of his nose. He can't help but crack a smile at the absurdity of the question. “It’s not like that.”
“I am designed to facilitate your performance in combat by whatever means possible. In addition, I found the sensation quite satisfying.”
Cooper’s eyes snap open. “What?” Shit. “You simulate my nervous system.”
“Correct.”
“So you could…feel that? I thought it was just for medical purposes.”
“The simulation takes into account all stimuli. I am currently restricted to monitoring, however.”
“Restricted...to?”
“Titans are not permitted to influence their Pilot’s nervous system without direct consent. Unless, in times of inability to properly communicate, due to a medical emergency.”
“Influence…you mean pain suppression?”
“Correct. However, a human’s sense of pleasure is also controlled by its nervous system.”
“Shit, BT.” He pops the latch, opens the cockpit door and jumps out. He needs air.
“This is only theoretical, though. Use of root access to a Pilot’s nervous system outside of medical purposes is not advised.” The door seals shut and BT’s optic turns to watch his Pilot.
“Yeah, I get it.” He lies down on the grass beneath BT.
“You did not directly answer my question from before, Pilot.”
“About what?” His head’s spinning. He needs a drink and some sleep; not whatever the hell this is.
“I asked if you would be willing to demonstrate it for me.”
“You really want to see me jack off, don’t you?” He looks up to see the Titan’s optic shift. Again, the absurdity of the situation twists his features into to grin.
“Is that the colloquial?”
Jack snorts. “Yeah.”
“If it would benefit you, I do see value in understanding the process.”
“So you could…what? Help me?”
“If that's what you want.”
“Do Titans ask to see their Pilots get off a lot? I mean...is this a regular thing, or am I just special?” There’s annoyance in his voice, but he’s not mad. Either he’s overreacting to something that somehow makes sense, or BT’s AI is leaning towards being a bit too curious. It’s never been an issue before, hell, it’s why he chose to stay with him, but…shit.
“I am following my protocols. Why does this concern you?”
Cooper puts his hands up. “Alright, alright. Tell you what. I let you...watch me, but you have to let me worry about it from now on. I appreciate your curiosity and all, but it's something I gotta do on my own.”
If I don't have to wait until getting back to base every time, it's not such a hard pill to swallow. Right?
“Is that what you want?”
“Sure,” Jack concedes.
“Then I agree.”
Jack nods. “Alright.” His hands wave outwards dramatically. “You want me to just go for it, or…uh, do you have questions?” He’s already regretting ever entertaining the idea.
“Is it a purely physical action, or is there a drive behind it?”
“Well, you - humans - usually think of something that turns them on. Makes it easier.”
“Turns them on. Colloquial for arousal?”
“Yeah.” His fingers flex, the fabric in his gloves groaning.
“What sort of things do you think about during masturbation, Pilot?”
“Whatever comes to mind.” Cooper can feel his cheeks burning up. The sun’s nearly gone, and the glow of BT’s optic is dying his uniform a light blue.
“And then what?”
Jack stands, turning to face his Titan.
“Then…you just do it.”
“Are you going to demonstrate it?”
He sighs. “I know you don’t understand why, but…it just feels weird.”
“I have no intent on judging you, Cooper. I understand this can be a concern for many humans.”
“Tell me about it.”
“Would you like me to help?”
Jack bites his lip.
What the hell am I doing.
“Is that what you want, BT?”
“I want you to feel good. In addition, I interrupted you earlier.”
“Feeling good…that’s an extension of Protocol Three, right?”
“Correct.”
That makes at least a little more sense.
Right?
“Ok, ok. Do it.”
“Do you consent to allowing Titan BT-7274 full access to your nervous functions?”
Jack looks into the optic, already feeling exposed in its light. He nods, more to himself than his Titan.
“Yeah.”
A moment passes. Static builds up in the back of his head, signaling a successful handshake.
“Pathway confirmed.”
That was too easy.
“So you can...control what I feel now, huh?” Jack asks sheepishly.
“Influence would be a better description. In addition, even root-level commands are still under the direction of all Protocols.”
“Right.” He looks down, feeling that familiar fuzz in his mind as BT re-establishes the link. “Be careful, ok?” It’s strange how comfortable this feels, what with BT right there. Whether or not he's the reason why requires more thought than Cooper can spare.
“I won’t hurt you, Pilot.”
Cooper can feel a warmth spreading out from his chest, breaking off into smaller strands as it travels out to his arms and legs. It isn’t intended to arouse, just…make him feel good, like the Titan said.
“BT, that’s…that’s you."
“Correct.”
“Holy shit.” He raises his hands, watching them tremble slightly. It feels wrong and thrilling, all at once. Possibilities flash across his mind.
“Do you want me to help you masturbate, Pilot?”
Jack's eyes close, his brain trying to focus. He did promise, and if this feeling is just the test drive, walking away now feels like a shitty way to end his night.
“I can trigger specific points of contact, if that helps,” BT adds.
Cooper realizes that he’s hard again, straining the fabric between his legs.
“This still feels so odd.” The warmth travels up to his skull, ridding him of the slight headache he’d gotten over this whole ordeal. A cocktail of pleasure response and the nullification of pain, he figures. BT always was a fast learner.
“Do you want me to stop?” BT rescinds the orders to his Pilot’s body.
“No.” His lips remain stationary after he says it, jaw slack. Every muscle in his body is aching to feel that sensation again, begging to see how good BT can make him feel. But that thought, it keeps coming back.
“Doesn’t this feel odd to you?”
“Pilot, if I understand you correctly, the reason you don’t feel comfortable is the human predisposition towards keeping anything physically intimate private. Correct?”
That’s one way to put it.
“These are the kinds of things that humans do together only if they trust each other.” He rubs the back of his neck.
“Do you trust me?”
“Yeah,” He scoffs. “‘Course I do, BT. But...you’re not human.”
“Pleasure is a chemical reaction, and I am simply inducing it, Pilot. As this is not classifiable as a medical emergency, though, I understand if you no longer want to proceed.”
He swallows, that warmth filling his mind. “I want you to.” Fuck. “I want you to make me feel good.”
“Affirmative. Please advise.”
“C-can you...touch me?” He doesn’t know why he says it. It doesn’t make any damn sense logistics-wise, but he wants it. He puts a hand over his clothed erection and looks up at BT. “Here. Physical contact feels good…here.”
BT adjusts his arm, extending it out in front of Cooper and cupping his hand gently.
“Just be gentle, ok?” He bites his lip, hands uneasy at his sides. The Titan could crush him without even trying.
“I won’t hurt you,” He repeats. BT shifts his hand slowly, until it’s just barely grazing the fabric of Jack’s pants. He tilts his fingers up slowly, dragging it across the surface as softly as he’s physically able to.
“Fuck…” Jack drops his head back. Hard steel runs along his length, giving just enough friction to pull the few remaining doubts from his mind.
“This feels good.” BT's optic is locked onto his Pilot's body.
“Yeah, buddy. It does.” He’s panting. He bites back a groan when he feels it again, this time a bit harder.
“I’m noticing an increased amount of blood flow to your pelvic region. Is this intended?”
“Yeah--” Cooper cuts off when BT’s fingertip grazes over him again. “It is.”
“Would you like me to increase the pleasure in that region?”
His knees just about give when he hears those words. In a gasp, he pleads for it.
“Affirmative.” BT sends the commands to the Pilot’s brain.
“Aaah--” Jack’s hands fling upwards as a searing warmth runs through his cock, feels the stickiness of precum against his stomach as pleasure tears through the muscle. “Jesus. BT...just like that.” He takes a few cautious steps towards the Titan and puts his weight on it, not trusting his own legs to get the job done anymore.
“More?”
Jack laughs, exasperated.
“More.” He curses as it happens again, bites his lip hard enough to draw blood as a 25-foot heap of metal blows his fucking mind.
“Your heartbeat is unusually high for a resting position, Pilot. Are you sure that this is safe?”
"Don’t stop.” His fingers wrap around the gaps in the metal guarding BT’s leg. His body presses against it, hips grinding in time with the waves as they hit. BT’s exterior is lukewarm, unyielding metal. But fuck if this doesn’t feel good.
“Cooper, my systems indicate that you are approaching the threshold of overexertion.”
“That’s the idea.” He grits his teeth, decency be damned as he starts rutting up against his Titan. His breath is coming in shorter and shorter bursts, legs tired of pressing up at this awkward angle. “You think you can give me more?”
“You are already at the imposed stimulation limit.”
“I consent-” He gasps as another shot of precum runs down his length. “I want you to push it further.”
“For what purpose?”
Jesus. Was that a tease?
“I want you to...make me cum. BT, please...”
“Affirmative.”
Jack yells, feels every nerve in his cock light up and push him until he’s sputtering against BT’s chassis, crying as he makes a mess in his suit. BT doesn’t stop the flow of signals to his brain even when he’s exhausted, hastily reaching into his underwear to nurse his still-sensitive dick with his fingers.
After a moment, when Cooper can think but still not see straight, he proclaims: “Jesus.”
“Pilot?”
“I-I don’t know what the fuck just happened, but...” He stops, catching his breath.
“Analysis: you have just experienced an abnormally pleasurable orgasm.”
He wheezes out a laugh, one hand on BT’s leg as he hunches over, gasping for air. “Right.” He takes deep breaths, still feeling the aftershocks of what just happened. “That was...incredible.”
“So I was correct in my assumption?” BT’s hand lowers and stretches out, giving Cooper a place to collapse into. He raises the Pilot up until he’s a foot out from his optic, studying his expression. It’s not something he’s seen before.
“This--” He gasps, still in hysterics. “This can’t happen before a mission, BT.” He closes his eyes, letting his head fall back in the Titan’s rubberized palm.
“Agreed. Your body is exhausted, Pilot. Sleep is recommended.”
“No shit.” Jack can feel his pulse returning to normal, even as his fingers are still tingling. He doesn't wanna think about the mess in his suit; he'll find time to wash up before the mission.
“Briggs has requested us in under five hours, Cooper. Would you like to remain here and sleep, or return to base?”
“BT?”
“Yes?”
“How do you do something like that, and then go back to talking normally like nothing happened?”
“I have performed my functions. My next priority is making sure you receive adequate rest before the mission.”
“Didn’t you feel all that?”
“The simulation contained an overwhelming amount of pleasure.”
“Did you...like it?”
BT’s optic shifts away from Cooper, looking out somewhere beyond him before returning.
“I did. Making you feel good makes me feel good, Pilot.”
“‘Course.” Jack snaps out of whatever fantasy he was cooking up in his head. "Just following Protocol."
“Correct. Have you made a decision on where you will sleep? You should begin the process soon if you intend to get at least the recommended five hours.”
“Yeah.” He lies back, letting his legs dangle off of BT’s fingertips. He pats the metal. “Right here’s good, big guy.”
“Understood.”
Cooper folds his arms behind his head and closes his eyes.
“Sleep well, Pilot.” The Titan’s optic fades as it reenters standby mode.
Jack snorts, bewildered. Countless stars fill his vision as he glances up. Earth is somewhere out in that expanse, watching him, impossibly small as it may seem from here.
He smiles as the thought passes.
“Night, BT.”
