Work Text:
A Bruce who recruited Robin as a soldier is dismayed when he presents omega. He tries to fire him. Dick resists saying he's the same person who has already proven in training and in the field that he can withstand pain, injury, and risk of death. Bruce says then before Dick can go in the field again he needs to prove he can withstand sexual assault.
Dick's adamant that he can handle anything. So Bruce constructs a fucking machine challenge for Dick. (Obviously he's not going to rape Dick himself, he's not a rapist [he thinks]; this is TRAINING.)
First a simple, unrealistic dildo which jams into his virgin pussy with no foreplay. Restraints which keep him down and unable to escape as he moans and groans around the jackhammering thrusts of the machine. Bruce thought this would be all it would take to convince Dick to quit, but he's wrong. Dick doesn't beg for relief and when Bruce lets him out of the restraints the teen is triumphant.
Training isn't just one day, though. Sure Dick has passed the first test, but that was too easy, in hindsight. Bruce will prove that Dick needs to quit. And this time Alfred is not going to interfere like he did with the hunger training.
Next day Bruce puts Dick back in the same restraints, but this time the machine is set up to fuck Dick's ass. Unlike the first time which went hard and fast with no prep, this time Bruce sets it to go torturously slow, with plenty of lubricant. Dick is red faced and mortified when his untouched little cock shoots watery cum when the fake knot expands inside his ass. But he doesn't ask for mercy, and Bruce makes no mention of his orgasm when he finally lets the boy loose.
Bruce devises and builds a more elaborate machine. One with multisensory improvements. In this machine Dick is blindfolded and on hands and knees. The dildos fucking his pussy and ass are much more realistic, that Dick can feel the veins and ridges as they slide in and out of his walls. The most degrading, victim blaming, misomeganistic porn recordings Bruce could find play. "Greedy little slut. Omega whore. Knew you'd love being raped. Gonna make you into our cum dump."
Dick never complains... instead it almost looks like his Robin is enjoying himself.
There's a puddle of omega cum under the teen by the time the fake knots begin to catch in his holes, and Dick gasps and orgasms again when this time he's stuffed full of artificial alpha cum.
Without consciously deciding to, as he watched, somehow Bruce's cock got out of his underwear and he found himself jacking off to the sight of his debauched sidekick. He cums all over Dick's trembling back.
Once Bruce cools off from his orgasm, he gets himself sorted so it looks like nothing happened before he sets the machine to deflate the knots and takes off Dick’s blindfold. Dick won’t know that the cum cooling on his skin is Bruce’s real cum. This bizarre impulse he had meant nothing, Bruce thinks. Except… as Dick wipes himself off and gingerly sits up, Bruce feels deep satisfaction that Dick now smells marked.
“Holy boredom, Batman,” Dick says with his cheesy grin still undimmed, “real knots don’t take that long to go down, do they?”
Bruce grunts.
“Well? I proved myself, didn’t I?”
“You did well,” Bruce says, and a smile tugs at his mouth when Dick glows from this mild praise.
The next day, at breakfast, Bruce is in a bad mood. Dick is all showered and back to smelling like an unclaimed omega.
“You got anything planned for us, Bruce?” Dick asks.
“No.”
“That’s okay,” Dick says cheerfully. “I’ll see if the other Teen Titans have anything for me.”
“Something wrong, Master Bruce?” Alfred says, noticing the twitch in Bruce’s face when he comes to refill the coffee.
“Nothing that can’t be fixed,” Bruce answers.
Dick goes off to his high school, and Bruce makes an appearance at a board meeting, but his mind is elsewhere.
Having Dick infiltrate and control the sidekicks of other heroes had been a good idea before, but now...
Ollie's boy was an alpha for sure, and who knew how to determine the dynamics of metahumans like Aqualad or Wonder Girl?
Bruce had always trusted Dick's control over the other Titans, but...
Then a far more dismaying thought occurs to him. What if Dick willingly sexually experimented with the others? Or even fancied himself in love with one of them? What if he let one of them mark him?
Bruce trusted Dick, but love and sexuality was unpredictable. Not to mention heat. Bruce remembers how Dick had quickly come to enjoy the fucking machine, though neither of them acknowledged it. How much lewder would his body be in heat?
Unpredictability was not acceptable.
Clearly, Bruce needs to eliminate any possible distraction from the mission.
And there was one obvious way to do that.
Bruce simply needs to claim Dick himself.
He examines the idea from all angles and sees how logical it is, then when he shifts in his chair he realizes he has an erection.
He cuts the board meeting off abruptly, with the blithe indifference of Brucie Wayne, and goes home early to work on his plans.
It is much harder to focus as he works this time. Bruce keeps getting distracted by the thought that he will have taken Dick's virginity in every way. He will be the only alpha to ever enjoy Dick's pussy. Dick's body and mind will both belong exclusively to him.
When Dick gets home from school, Bruce calls him to the Batcave.
Dick shows up in his Robin costume, then has the sass to roll his eyes when he sees the training machine set up had been significantly altered yet again. The dildo arms are folded away; in fact it looks more like an ordinary nest than a machine, though the restraints are still visible. "I thought you said you didn't have plans."
"I had to recalculate," Bruce answers. "Yes, you impressed me with your ability to stay resilient from a simple assault. But in the field, with a real assailant rather than a machine, would you really have no emotional attachment to your virginity?"
Dick laughs. "Wow, you are so old-fashioned. Geez. I know what I'm risking, Bruce, and I think I already proved that I can cope if things go bad, but now you're acting like it's a certainty that I'm going to be raped. Trust me, I'm going to fight like hell to make sure that I lose my virginity on my terms."
"That's not good enough," Bruce says. "Not when we can make sure it's not a problem."
Dick tilts his head, looks at the machine-nest, and looks back at Bruce. "How, exactly?" he says slowly.
"I can take your virginity. I would make it a good experience. An additional benefit is that this would satisfy any curiosity you have about sexual intercourse."
Dick doesn't laugh this time. "You're serious."
"I wouldn't joke about it."
"No," Dick says. "Wow. Gosh. Uh..."
"You have a question?"
"...How much of the Brucie Wayne reputation is accurate?"
"Which part of it," Bruce says, knowing, but wanting to hear Dick say it.
Dick blushes. "Oh, you know... the Casanova part."
"I have a certain amount of experience." For the first time, Bruce turns his most seductive smile on Dick. "Are you curious about that as well?"
"Have to be made of stone not to be," Dick confesses, cheeks still flushed, but adds with daring, "So you'll satisfy my curiosity?"
"I will satisfy you in every way," Bruce growls, picking him up.
He lays Dick down and slips those pixie boots off, pressing a kiss to the arch of the teen's foot. Dick clearly didn't expect this tenderness, squirming and attempting to tug his foot away, but Bruce keeps his grip and kisses the ankle, then up the leg. Big hands grip those scaly green panties and tug them down, forcing Dick's knees together for a moment, but afterwards Dick spreads his legs wide.
Bruce is good at everything and eating pussy is no exception.
Despite his eager, slutty display, Dick squirms again against Bruce's hands when Bruce gets his face in close. "Bruce! Your stubble!" he whines, then keens as Bruce licks a stripe from his hole to the tip of his cute little cock.
Damn, his little Robin tastes so good. Slick coats Bruce's palate and dribbles over his jaw as the omega's body responds to his licking and sucking. It's dripping down between those gorgeous fat ass cheeks to his other hole as well, the pink little bud seeming to wink at Bruce.
He'll take Dick's virginity there tomorrow.
"Nnngh, Bruce," Dick keens as he cums when Bruce jerks him off while tongue-fucking him. While he's still boneless from the orgasm, Bruce flips him over and gets him restrained in the presenting position.
"Kinky," Dick teases, and Bruce slaps his ass to watch it jiggle.
No wonder the machine didn't scare him off the mission. This sweet little bitch is made to be fucked. Bruce must be blessed by the universe, to have a sidekick that will fight by his side in the field and then take his cock afterwards. As Bruce pushes his fat cock inside Dick, he can't help grinning, imagining what the rest of the Justice League would think of this development.
My little Robin, all mine. I'm gonna make him my fucktoy too, and you can't do a damn thing about that either. It's only gonna make us a better team.
"Ohhhhh my God," Dick moans as Bruce fucks him. "That's so good!"
"Told you," Bruce grunts, and smacks his ass again, because he wants to see a nice cherry red by the time they're done. "Who's fucking you, brat?"
"B-... B-..."
"Who's fucking you?!"
"Batman!" Dick squeals and Bruce can feel his pussy clenching down on his cock.
Bruce grabs Dick's cape and uses it like a leash as he fucks his boy—his pet.
"Okay, listen up," he growls, "I'm going to knot you now, and you're going to thank me for it."
Ordinarily Dick would have had some sassy comeback to this, for sure. But not now, not when he's cock-drunk and craving cum.
"Thank you!" Dick cries out when Bruce's knot brutally plugs up his cunt. "Thank you, thank you—mmmm, thank you for your knot, thank you!"
Bruce throws his head back, enjoying the euphoria of his own orgasm, until his head clears and he looks back down, and frowns.
That damn collar.
Dick is panting, face turned to the side and eyes closed.
"So," Bruce starts, and Dick opens his eyes, meets his gaze. "Did I tell the truth? Good experience?"
"Uh, yeah," Dick says, and his bright boyish grin hasn't changed a bit. "Holy experience, alright. Now I know why Catwoman doesn't try too hard to escape. So how long until your knot goes down? Will we be able to go out tonight?"
The idea of Dick making one of his beautiful kicks to the side of the head of some goon, with Bruce's cum in his belly, is going to make this one of the longest lasting knots Bruce has ever had. "Few minutes. And yes."
"I'll have to tell the Titans we're postponing." Dick tests the restraints on his left hand, and laughs. "Gosh. Wait til I tell 'em I lost my v-card to the Batman."
Wait until you tell them that you're the Batman's omega. But that will wait for another day.
First, fuck Dick's ass.
Then get that big mouth around his cock.
Then sabotage his suppressants.
An image of Dick round with child, his child, tiny tits leaking milk, flashes into Bruce's mind.
He files the image away with regret. The birth control would have to stay.
But getting his teeth into his little Robin's neck... oh yes.
Dick being an omega was the best thing for the mission after all.
