Chapter Text
It isn’t often that Tim asks for help – so Dick makes it a point to give him his undivided attention when he does.
“Uh, you do know hypnosis isn't real, right Timmy? But hey, if it makes you feel any better about your project, go ahead and try it on me.” Dick grins, leaning back into the couch. “Just don't come crying when it doesn't work.”
Tim rolls his eyes but starts setting up all the items he needs for his experiment. Dick doesn’t have to know it’s a rare mystical artifact, one that he’s been hunting for months. No such school project exists.
“Just stay still, okay?” Tim says, swinging the medallion in front of Dick’s face.
He waits a couple seconds, and a sly smile spreads across his face. He’s under. Dick’s face has relaxed, looking blankly forward at Tim.
This hypnosis stuff might be more effective than I expected, Tim thinks.
Tim starts off conditioning Dick to become aroused at the thought of Tim, to feel the need to be fucked by Tim. It’ll take some time to kick in, but Dick seems agreeable while under hypnosis. His eyes are heavy lidded and he nods along as Tim talks.
He then lines up a slew of trigger words, and describes the action attached to each.
“Boy Wonder – you will have a spontaneous, mind-shattering orgasm.”
“Pretty – you will immediately empty your bladder.”
“Bedtime – you will come to my room once the coast is clear at night.”
Tim adds a few more and decides to stop there. He says the designated ‘off’ command, and Dick is pulled back into consciousness, still laughing about Tim’s clearly failed attempt at hypnosis.
____
It starts in Dick’s dreams. They’re filled with inescapable desire for Tim as the hypnotic conditioning takes hold. He tries to resist, to push the illicit thoughts away, but it's a futile struggle.
Images of Tim, his smaller body but his surprisingly large cock, coming to Dick’s bed, pushing between his thighs and taking him. And it makes Dick so fucking hard.
Dick runs a hand through his hair, trying to clear his head when he wakes. The things he wants to do… but they’re brothers. This is wrong. He can’t take advantage of his younger brother – he never thought this way in the past, but everytime Tim appears now, all Dick wants to do is sit on his cock.
Dick starts feeling an unfamiliar heat building inside of him whenever Tim is near. And he hasn’t yet explored his sexuality with anyone, so this is an entirely new experience for him. Maybe he should spar with Tim. Maybe it’ll help him feel less restless, Dick lies to himself.
Tim puts on a big smile when Dick asks him to spar. The entire time, Tim makes sure to rub his cock against Dick’s body – making sure Dick can see the tent in Tim’s pants, even if he doesn’t notice how inappropriate his own hard-on is.
“Thanks for sparring with me, Timmy. I’ve been feeling so… restless lately. Thought working off some steam would help.”
“Of course, Dick. Anytime you need.” Tim answers, stepping closer to Dick.
Dick’s panting and sweaty when they’re finished sparring, and Tim decides this is as good a time as any to try out some commands. They’re alone in the manor, so there won’t be anyone to disturb them.
“You still look pretty when you’re all tired, you know,” Tim says, voice loud and clear.
Dick freezes in place, a sudden and intense wave of submission washing over him at the sound of that simple word. Pretty… His body betrays him, a warm wetness spreading in his pants as he fights not to obey the automatic response.
“N-No, I can't...what's happening?” Dick’s voice shakes, torn between confusion and arousal. “This isn’t… I can’t…”
Despite his protests, he remains in place, the loss of control mortifying. Tim just stands there, watching as Dick blabbers in confusion in his piss-soaked pants. His conditioning is working perfectly.
“Hey, Dick – you’re fine. Don’t worry. It can happen to anyone, you just said you’ve been feeling restless recently.” Tim looks concerned and sympathetic. “Let me help.”
Dick is equal parts relieved and embarrassed as Tim steps in to help clean the evidence. Tim’s hands are hot on his skin as he tugs at Dick’s waistband, slowly pulling off his pants.
Dick shouldn’t be so comfortable letting Tim help him with such an embarrassing situation, but he weirdly feels at ease with Tim’s touch. Despite the lingering embarrassment, his body responds, cock half hard, achingly aware of the forbidden line they're toeing.
“S-sorry Tim. I don’t know… Must be all those energy drinks I've been guzzling.” Dick’s eyes have unshed tears in them, the humiliation still shooting through him, but he laughs weakly, trying to pass off the incident as nothing.
“Already forgotten, don’t stress, Dick!” Tim says enthusiastically, smacking Dick on the ass as he turns to walk away with Dick’s pants. “I’ll grab you another pair.”
Dick can feel himself hardening even more, at war with his brain as he tries not to just beg Tim to fuck him.
___
Tim continues to play with Dick, slipping trigger words into his daily chats with Dick. Tim is pleased with how Dick’s hypnosis is coming along, and he tries a trigger word on Dick while they’re at Sunday dinner. Dick, Bruce, Alfred and Damian are all seated around the table, chatting away about the newest cases popping up in Gotham.
Damian is complaining about “father not allowing him to drive the Batmobile” once again, grumbling loudly.
“You should know by now – the only one who can get Bruce to change his mind is Boy Wonder over here,” Tim laughs, eyes darting over to Dick.
Dick looks like he’s about to retort, but he’s caught in the grip of the trigger, going rigid for a moment, his breath stuttering, before waves of involuntary pleasure crash over him. His hands fly down to grip the chair he’s sitting on, and he lets out a moan.
The unexpected, public orgasm leaves Dick reeling, mortified beyond belief. Oh Jesus, no...not here.
“F-fuck…” Dick half whispers.
He can feel the sticky residue in his boxers, the cum hot and wet clinging to his softening cock. What the fuck is he going to do? He’s literally losing control of his own body. What is wrong with him?
Dick’s cheeks burn with humiliation as there’s a pause before anyone speaks.
"You okay, Dick?” Tim asks, then turns to the rest of the family. “Dick wasn't feeling well earlier. Must be a twenty-four-hour bug or something."
The excuse, despite its flimsiness, breaks up the awkward, confusing moment. Bruce's gaze, ever watchful, scrutinizes the scene, searching for any signs that might contradict Tim's explanation. But there's nothing overtly suspicious.
Tim makes his way over to Dick and helps him up, hand pressed against his lower back. Tim's actions seem almost choreographed. Despite the obvious height difference, there's a subtle dominance in the way Tim helps him, bringing him out of the kitchen as he’s still in a panic.
Dick's body starts to shake with muffled sobs as Tim ushers him up to Dick’s room, closing the door firmly behind them.
“Shh, shh...it's okay, Dick. I've got you.” Tim's voice is gentle, a soothing balm on Dick's raw humiliation.
“Tim...I-I'm so sorry...I don't know what came over me. Thanks for getting me out of there.” Dick continues to cry. He’s pathetic. Relying on his little brother to help him when he’s clearly a huge pervert, ready to cum at the dinner table.
Tim helps him out of his pants, once again, becoming way too often of a situation. Dick has to turn away as he sees the sticky strands of cum pull away from his cock.
“This is getting out of hand, Tim. I can't keep having accidents like some kid who can't control himself. I'm sorry you've had to see me like this. I must look pathetic.”
“C'mon now, let it all out. We'll figure this mess out, I promise.” Tim’s hand rubs circles into Dick’s back.
“Why is my body doing these things? W-Why can't I control myself?” Dick’s voice cracks, and he wipes roughly at his eyes.
“This isn't your fault. You’re just going through a lot, Dick.” Tim's expression is sympathetic, the desire to protect his older brother palpable. “You don’t have to hide yourself from me.”
Dick buries his face in Tim's neck, sniffing and wiping his tears on Tim's shirt. He says "You always know what to say Timmy," while still blaming himself for the situation.
Dick's vulnerability tugs at Tim's heart, making him almost wish he could take all the hurt and confusion away. But what would be the fun in that?
“It’s going to be okay. Why don’t you clean yourself up? It’s almost bedtime.”
