Work Text:
Bro knows he's more than a little fucked up. He's come to terms with it. A normal person would not do the things he does, would not have such a loose sense of morals, would not permit their desires to overrule their common sense.
Looking down at his little brother, Bro is pretty sure everyone else is missing out.
D is beautiful. Sprawled out on his bed, stripped completely naked, Bro is able to sit and watch him as much as he wants. He can let his gaze roam greedily over D's soft lips, down the slender line of his neck, over his chest- flat for now, but that will change- and down his smooth stomach. His soft cock hangs between his legs, his long legs stretch out on the bed, slender and smooth.
And, of course, around his neck is the electric collar. Bro hopes he doesn't have to use it- but it's a safety precaution. He's not letting D leave him again.
He watches the fan of D's pretty lashes against his cheek as his chest rises and falls in slumber. His lips are so plush and perfect, begging to be kissed and nibbled on, perfect for wrapping around Bro's cock.
Bro is broken out of his musings as D stirs, a weak moan leaving him. His eyes flutter, one hand raising up to his head- he's probably got a massive headache from the drugs Bro used on him, so Bro plucks the glass of water from the nightstand and moves over to the bed, kneeling and helping D sit up with a murmured, "easy, lil'bro. I gotchu."
"Bro..?" D mumbles, fingers weakly clutching the glass as it sips from it. He blinks a couple of times as he comes out of his haze, glancing around. "What… what happened..? Where am I?"
"You're home," Bro tells him. "With me. I ain't lettin' you go again, D."
"What?" D seems to realize he's not wearing his shades- or anything at all, drawing his legs up and looking around anxiously. "What are you- what's going on?"
Bro plucks the glass from D's hands and puts it back down, then swings around on the bed, grabbing D's wrists and pinning him down. D's eyes go wide- shock, confusion, fear, they all slide across his face as Bro leans in.
"I'm done lettin' you run around sluttin' it up in Hollywood," Bro tells him, tone serious and firm. "I shouldn't have ever let you go in the first place. You left me, D- so you ain't ever gonna leave me again."
"H-hey, Bro…" D tugs at his wrists weakly, completely pinned and helpless. He's always been the weaker of the two of them. "This- this isn't funny, come on… let me up, it's not April, you know? This is a pretty shitty prank…"
"Oh, I'm bein' serious, D," Bro growls. "You're mine now. I'm never lettin' you go- and I'm gonna make sure you know who you belong to." He lazily rolls his hips, grinding his hard cock against D, who goes white.
"No, no- dude, don't, come on, you don't want to do this…" D says, voice going high. "Bro, come on, I'm your brother, this is wrong, you shouldn't-"
"Hush. Relax for me and I'll make sure you feel good, D," Bro purrs, leaning in and kissing D's neck- starting to suck and lick, intending to leave a whole array of marks behind.
"No, no no-" D gasps, starting to struggle again, so Bro hauls his wrists up into the prepared cuffs and clicks them into place, trapping D with his wrists cuffed to the headboard.
Perfect.
Bro slides his way down D's body, kissing and licking over his skin, worshipping his baby brother's silky-smooth, tanned body. He knows his brother loves going to the beach to show off what he's got- and now, the only one he'll be showing off for is Bro.
"Love you, D," Bro croons, as he kisses D's cute stomach. "I'm the only one who really loves you. I'll show you that."
"No, Bro, please…" D lets out a wet little noise, weakly tugging at the cuffs- but his cock is starting to fill out under the attention. Bro laughs and gives it a wet little kiss to the tip, making D whimper.
He hikes up his brother's legs, folds them against D's chest, and goes to town on his tight little pucker, licking and nipping at his cheeks, tonguing his way into D's tight hole as D cries out, writhing, protesting as his cock bounces and jerks eagerly. His body betraying him, showing how good he feels. It's a wonderful sight.
When Bro sinks his cock inside of him, it feels like coming home. D is tight and warm and perfectly made to take Bro's cock, sobbing and whimpering as Bro relentlessly hammers his prostate, pinching and tugging and sucking on his cute little nipples as he fucks D into a hands-free orgasm that has his eyes rolling back into his head as his cock spurts out pulses of cum across his stomach.
Beautiful. Bro gives D a long, wet, messy kiss as he cums, savoring the taste of his brother's mouth. D weakly cries and shakes, but that's alright- he'll come around before long. He won't have a choice.
——
"What… what is that?" D asks, scooting backward on his bed, face pale as Bro approaches. It's the first time he's spoken to Bro in the three days he's been here- resolutely ignoring him, not saying a single word even as he wanders around in his room like a cat. Bro keeps the door locked, of course, it's not until D starts showing good behaviors that he'll allow D out into the apartment properly.
"Stimulants," Bro says. "I told you, D. I ain't gonna let you forget who owns you- so you're gonna be my sweet little cow."
"Your what?!" D presses himself back against the headboard, eyes wide as Bro sets the tray down on the desk. "No, no no no- no fucking way, dude, I don't know what the hell is going on in your brain- no, get off me-!" He flails, kicks and thrashes as Bro pins him down- but Bro has always been the better fighter, so he forces D's wrists back into the cuffs without any trouble. D whimpers and yanks at them as Bro retrieves the tray and sets it down on the bed.
"Now," he picks up the bottle of pills and shakes them at D pointedly, "you can either willingly take these or I will give them to you as a suppository. Don't think I won't."
D swallows nervously. The label's been stripped off- he has no idea what Bro is going to give to him. He doesn't need to know, either. It's a black market drug for a reason.
"What… what is it?" D asks. His eyes dart between Bro's face and the tray.
"Nothing you need to worry about. Open up."
D grits his teeth as Bro shakes out a pill- and then, because Bro is right in that D is an obedient little brother, he opens his mouth and lets Bro put the pill in and swallows it down with water.
"Open," Bro orders and checks to make sure that D didn't hide it under his tongue. "Good boy." He ruffles D's hair and enjoys his disgruntled expression.
"I'm not a dog," D mutters and Bro chuckles, picking up one of the injections.
"Nope," he says, "but you are a cow. My cow."
"Oh, ohhh, no, no, please Bro, no, don't- d-don't-" D shrinks back, face going pale, as Bro reaches for his chest, groping over the barely-there mound until he can gather up a bit of flesh in his hand- D jerks his head away and lets out a pained little cry as Bro sinks the needle in and injects D's tit with the drugs. He repeats the process with the other one as D bites back a sob, then picks up the last needle and injects it into D's thigh.
D slumps against the bed, breathing erratically as he cries. Bro clears away the tray and unlocks the cuffs- D pushes at him weakly but Bro just bundles him up and moves them around so that he's sprawled out on top of D, massaging his chest.
"H-hurts-" D whimpers, trying to push him off.
"Shh. I know, baby. But you gotta get through the hurt to get to the good." Bro lowers his head to one of D's nipples and starts to suck- milk takes a lot of stimulation to get going and he'll be damned if he's going to neglect his baby brother's body.
——
At the one-week mark, Bro can tell that the changes are taking effect. D still fights him, still has to be cuffed down for his injections, but his behavior is changing. Every day, Bro spends several hours sucking on D’s developing tits and massaging his chest, encouraging milk production.
D’s started turning away from him when he enters the room. Crossing his arms over his chest like he can hide the little swelling mounds of plumpness, bringing his legs up like he can hide the way his dick gets hard at the sight of Bro. Pavlovian training at its finest. Even if his mind rebels, his body understands that Bro brings pleasure and responds accordingly.
It’s a shame for D’s body that Bro is about to do something mean to it.
“D,” Bro sits on the bed next to his brother, putting one hand on his shoulder. “Turn over and look at me.”
“No,” D mumbles, curling into himself a little tighter. “Go away.”
“You know, I was plannin’ on letting you out of this room today,” Bro says casually. D goes still. “But I suppose if you wanna stay stuck in here…”
Slowly, D turns over. Arms wrapped around his chest. Scowling.
"...what do you want me to do?" D asks grumpily. Bro chuckles.
"Don't fight your injections today and we can go out and sit on the couch and watch a movie while I work on your tits. Sounds good?"
"You know, we could watch a movie without everything else you just said," D complains, but slowly, reluctantly, he uncurls.
"Good boy." Bro ruffles his hair and reaches for the needles. D winces and cringes and whimpers his way through them- but he gets through them and Bro helps him up to his feet, guiding him from the bedroom. D's eyes dart around hungrily, taking in the new space, and his shoulders drop in relief.
"Don't forget," Bro warns, tugging on the collar, "you can't go anywhere. You leave the apartment and this'll zap you good."
"I know, I know," D says, but he lets Bro guide him over to the couch. Bro waits until D's put on a movie until he twists them around and sprawls out on top of D, getting to work.
It's soothing, sucking and massaging on D's nipples. The soft, perky little buds slip into his mouth easily as he sucks and sucks, strong fingers kneading the soft flesh. D squirms underneath him, breathing hitched. Bro can hear the way he struggles to ignore what's going on with little choked sounds and swallowed moans. He can feel the way D's cock is getting hard against his belly- but he's not overly concerned about that issue. He'll deal with it eventually- D's gonna have to learn sooner or later that his pleasure isn't meant to come from his dick.
D's meant to be a cow. He's perfect for it, after all, and cows get pleasure from their tits. So if Bro savors the way D's expression twists in pleasure and he writhes underneath him as he gives his baby bro a quick handjob, well, it's only because eventually he'll make it so that can't happen anymore.
By the end of the movie, D is lying placidly on the couch, his eyes distant as Bro sucks and sucks and sucks on his tits.
Completely docile.
——
D's tits grow into plump mounds of flesh that Bro can squeeze in his fingers and watch them spill out through the gaps. D gets quieter, snappier, and Bro can tell he's afraid of the changes being made to him.
He's also so goddamn attractive that Bro feels like he just can't help himself. He lets D wander around the apartment now- completely naked, of course, cows don't wear clothing- but more often than not he finds himself with his hands or mouth on D's tits, pinning him against the nearest surface to grope and suck on his brother's sweet, perky nipples. D pushes at him, fights him still, but he also goes weak and crumbles with just a little bit of touch.
He's falling. It's beautiful.
Bro fucks him on his hands and knees and tugs on D's nipples like he could milk them and D cums with a scream, muffled by the pillows. They collapse into bed together and for the first time, D curls against Bro's chest as he weeps. Bro kisses his cheeks, kisses him, and holds D as he falls asleep.
---
At the three week mark, D starts getting fussy in a new way.
"Stop- stop fucking touching me, Bro, I can't- I swear to god, I will rip your dick off, nnnnhnh-" D whines in pain as Bro's fingers pinch his tits, squirming and trying to pull away.
"Hush, D," Bro tells him. "You're not gettin' out of this."
"But-" D gasps, pressed as far into the arm of the couch as he can go, "it- hurts, aah, ow, ow… Bro…"
"Does it?" Bro hums, gently thumbing one nipple and watching the way D flinches.
"Yes, you ass-! Aah, ow… You've c-chafed them to hell and back with your big, stupid- gorilla hands!"
"Hmm. How about this?" Bro dips his head and gathers spit in his mouth, wrapping his lips around one of D's nipples and sucking lightly. D squirms, whimpering, but his cock pulses against Bro's hip.
"T-that's… it still hurts, but…"
"A little better?" Bro murmurs. D nods on another whimper, turning his face away. "Alright. I'll pick up some cream for you."
"Th… thanks…" D sniffles a little, squirming under Bro. "Can… please, just for today, can you leave them alone…? They really hurt…"
Bro hums, then presses a kiss between the soft mounds. "Alright. Get some rest, baby. I'll go get that cream for you."
"Thanks…"
Bro slides off the couch and grabs his keys, tucking them with his wallet into his pocket, and looks back at D for a moment.
His handsome brother has only gotten prettier. It was a subtle, gradual change- but it's there, coaxed along by the drugs he's been getting injected with every day. D's lips are softer, his lashes longer, his cheeks plumper- his toned stomach is losing its definition and becoming soft and squishy, his hips are getting wider, his thighs squishier- he's getting curvier, especially with his growing tits. Bro isn't entirely sure, but he thinks D's dick might be shrinking as well, and wouldn't that just be perfect?
More feminine. More beautiful. More of the cow he's meant to be. His hair is growing out, too, and before long Bro will be able to take care of that, too.
"Love you, D," Bro says, and then he's off to the store. D doesn't answer him, but that's fine. He will someday, once he stops being stubborn and accepts his new life.
——
They find out just why D's tits were so sore just two days later. Bro's got his fingers massaging at the root of D's tits, sucking firmly as D moans and writhes underneath him, pretending like he hates it as he gasps out little no ’s and stop ’s, still fighting his place underneath Bro-
and then it's like a dam breaking. Between one suck and the next, Bro's mouth floods with sweet milk and D cries out, fingers scrabbling at Bro's back, clutching at him.
It's a triumph, victory roaring in Bro's chest as he sucks and sucks and sucks, swallowing down mouthfuls of sweet, creamy milk. His baby brother's milk, all for him. D is writhing and moaning, crying out in his high, sweet voice, babbling nonsense, a slurred mix of more and stop and Bro, Bro Bro Bro-
His. Bro’s. He breaks the sucking long enough to lunge up and kiss D hard, rutting his cock against D’s leg as they share a milky-sweet kiss, tears streaking down D’s cheeks.
There’s no going back now. D is his little milking cow forever.
“Mine,” Bro growls.
“No… Bro…” D sobs, writhing underneath him, but Bro doesn’t care. He drops his mouth back to D’s nipple and sucks more, draining every last drop from the sweet little mound before attacking the other one with his lips and teeth, coaxing it into releasing its milk in a sweet burst.
Bro fucks D on the couch, the taste of milk on his tongue, sweet and creamy and absolutely perfect. D cries, covering his face and sobbing as Bro rams his prostate until he cums hands-free. It’s his favorite sight, seeing D’s length pulse and throb as D twists in pleasure and tries to deny it.
But it’s not enough.
D is still resisting. Even though he’s finally producing milk, he’s still resisting- and Bro is ready to break that resistance.
He goes out to the shops that night and comes back with a cage. He locks away his baby brother’s dick without even a hint of remorse, even as D cries and begs him not to.
It's about time he stops indulging D's ideas of going back to being a man anyway. He's put on the charade of playing with D's cock for too long, with how hard D fights him about it- and for the first time, Bro regretfully uses the collar.
D collapses to his knees, spasming, whimpering, pissing himself. Bro can't help the way his dick twitches at the sight- his brother is just so beautiful when he's helpless. He carries D to the bathroom and cleans him up.
"I'm doin' this for your own good," Bro tells him, as he gently cups D's caged dick. "You gotta learn, baby bro- cows don't get to feel this kinda thing. I've been nice to you before this, but now that you're producin', you're a real cow- so this has gotta go away."
D turns his face away and doesn't say anything. That's fine. He'll learn.
Bro washes them up and guides D from the shower. He'll need to do some proper training to make sure D's body is accepting its new role.
——
It's amazing how much a denial of manhood can make someone more submissive. D quickly becomes more and more docile, the longer Bro keeps him in the cage. Maybe he thinks if he's good, Bro will let him out- but jokes on him, because Bro has no intention of ever letting D out. Maybe it's 'cause D's tits need damn-near constant attention- if Bro doesn't suck 'em dry, they start to leak everywhere.
It takes three whole days of not being able to touch his dick before D breaks.
"Bro, please, this is torture, take it off, I can't do this, please," D begs, hugging Bro from behind as Bro makes lunch. "It hurts."
"Hmm." Bro doesn't look back at his brother, though he can feel the soft mounds of his tits pressing against his back in a very enticing way. "I don't think you've earned it, D. You've been pretty stubborn this whole time when all I've been tryin' to do is help you be your real self."
"Please," D whines. "I need- I need to cum, please. I'll do anything, I- I won't fight anymore, just- please."
Anything? Maybe it's time to finally bust out the last set of drugs. "Alright. I'll let you cum- but only after you take a second round of injections. I've got some other shit I gotta start you on now that you're producing."
"Okay, yeah, sure," D agrees, relieved, "anything, Bro- anything."
Bro turns and ruffles his hair, then pushes D toward the bedroom pointedly. D goes to get settled in while Bro puts the food away, then retrieves the injections from the locked cabinet in the bathroom.
D is kneeling on the bed, squirming anxiously, one hand stuffed down between his legs, pressing on the cage. His poor dick must really be hurting, but Bro has no sympathy. It'll learn. He lets his eyes roam over D's soft body and look at his tits- he milked them dry this morning, so they're not as swollen and heavy as usual, but they're still sizable mounds.
"I've got a couple of 'em for you," Bro says, as he sets the case down and opens it. He wasn't expecting to use these drugs so soon- but as luck would have it, here's D, desperate to do anything.
"Close your eyes," he warns and D obeys, closing his eyes as Bro gently tilts his head to the side. This one goes in the neck- closest to the brain, he knows it will start taking effect quickly. Then one in the thigh. Followed up by two more, one for each tit- D is trembling when Bro is done.
“Shh, good boy,” Bro soothes him, guiding him down onto his back. “Good boy. Everythin’s gonna be perfect from now on, just you wait and see.”
“Bro..?” D squirms, clinging to him. “Aren’t… aren’t you gonna take it off?”
“Take it off?” Bro chuckles. “When did I say I’d do that? I said I’d make you cum, not that I’d take the cage off.”
“N-no… Bro, please…”
“Shh. Easy, lil’bro. I’ll take care of you.” He reaches for his toys, finding the dildo he's after, and slicks it up to ease it into D's ass. "Don't worry. You won't need that worthless dick of yours anymore, I gotcha."
"Mmhmf, ah…. ahhh, Bro… Bro…"
"Shh."
Bro smooths D's hair back from his forehead, watching as D twists and writhes on the bed as he firmly massages D's prostate with the toy. He can see his dick leaking through the cage- it must be agony for his poor little cow, but his body needs to learn. Bro lowers his mouth to D's tit and starts to suck, moaning in enjoyment as fresh, warm milk fills his mouth- and enjoying the way D's cries rise in pitch and volume.
He’s so proud when D manages to cum, fingers clawing at the bed as he sobs, hips jerking, cum spurting through his cage as he achieves the kind of orgasm that a cow should get.
“You’re such a good boy, D. You’re so good,” Bro purrs as he straddles D’s waist and sinks his cock between the soft, pillowy mounds of his chest. D looks up at him, sniffling and with red-rimmed eyes, and presses his tits together for Bro to fuck. It’s a heavenly slide and D even opens his mouth to catch Bro’s cum when he finishes, swallowing it down like a good boy should.
——
The new drugs start taking effect. D’s tits get even more sensitive- just one little suck and he’s moaning like a whore. He’s hornier than ever, thanks to the aphrodisiacs- but even though he’s starting to get dumber, he’s still fussy.
He still begs Bro for the cage off. He still tries to act like he doesn’t want Bro to nurse from his tits. He still tries to push Bro away- but it’s weaker and weaker, like he can’t quite remember why he’s supposed to be doing that.
Even when Bro gives him a good, proper dicking in their bed, playing with his tits and making him cry out in pleasure and cum in his cage, he still sobs and begs no, no no- and it's getting irritating.
He needs to break his brother's last little bit of resistance. But how?
It comes to him, surprisingly, after a nap.
Lying on the couch with D, drinking from one of his tits while D squirms and pretends that he's not getting turned on, Bro falls asleep. Could anyone blame him? D is so warm and soft now, squishy in all the right places, and sucking on his tit is a reassuring, soothing, familiar action… he just passes right out.
His dreams are warm and calm, full of D's milky scent and the sensation of touch, his hair being pet… and when he comes back to, D is nudging his head and whispering, "please, come on, please, come on, keep going, keep going," trying to get his nipple back into Bro's mouth. Trying to get Bro to keep sucking.
Bro obliges, latching back on to D's tit and resuming his nursing- and he can feel the way that D sinks into the couch, boneless, moaning with pleasure as his head drops back.
D must ache to be nursed from, if he's trying to get Bro to do it in his sleep.
So after dinner, Bro reaches down and unlocks the cage and says, "alright, there you go. You're free."
D stares at him, not understanding. Bro cocks a brow.
"Free?" D's voice is weak.
"Yeah. You're still fightin' me- so clearly you ain't gonna be a good cow for me. I ain't gonna lock your dick up no more, not unless you ask me to."
"...right. Um. Okay." D glances towards his room. "I'm gonna… uh…"
Bro waves him off. D can go try and jerk off all he wants. It's not gonna compare to Bro- especially if the medicine has done its job and made him impotent.
D shuts his door and doesn't come back out. Bro goes to bed.
In the morning, Bro wakes up to a tearful brother sitting on the couch.
"What did you do to me?" D gasps, the moment Bro steps out of his bedroom. "B-Bro, what- I- I can't-"
Ah. It did work, then.
"Get it up anymore?" Bro asks. D flinches. "It's cause your body knows, lil'bro. You ain't a man anymore. You're a cow."
"I-I'm not… I'm not…" D sobs, hands cupping his nipples, thighs pressing together firmly.
"Your tits ache?" Bro asks.
"N-no..!"
"I bet they're heavy. I didn't nurse last night, after all."
D looks away, face red. Bingo.
"Tell me if you change your mind. I'm makin' breakfast."
"Okay…" D says, miserable. Bro would almost feel bad, but D's had this coming for a long time.
It takes him until about three before he breaks, wrapping his arms around Bro's neck as he sits at his computer.
"Please," he begs. "It hurts- Bro, help me…!"
"What hurts?" Bro asks, as if he doesn't know.
"M-my- my tits, please… I can't… I can't milk myself, it's not…"
"It's okay, I gotchu. Come on." Bro stands up and guides D over to the couch, lying him down. D whimpers- his tits are heavy and full, bursting with milk.
"Relax," Bro murmurs- and then latches on to the first one. D cries out, hands fisting in Bro's hair, jerking up off the couch- Bro glances up and he can see that D's eyes are rolling back. A subtle little press and he can feel that D’s cock is still completely soft.
Perfect. D’s finally accepted his place.
“Bro- Broooo-“ D sobs out a moan, tugging Bro in, encouraging him on. “Please, feels- feels so good, Bro…!”
Bro holds D down effortlessly, loving the squish to D’s body, and sucks harder. D’s milk is still perfectly sweet and creamy- just as delicious as the first time. Bro’s never going to let anyone ever have a taste of it- it’s all his. D is his baby brother, his good little cow, and no one is taking this from him.
He sucks and licks and drinks down every drop as D's cries work up to a fever pitch, tugging on his hair and arching up against him, mewling desperately- and his wordless begging transforms into a slurry of words, a begging "Bro, Bro, please please please I need I need please more please please please," as he frantically yanks Bro towards his other tit.
Shit, maybe Bro made him too sensitive. This is hot as hell, though, so he pulls back, wiping his mouth, and crushes their lips together in a hot, hungry tangle of tongues. He can feel something hot between them, down by his hips, and his brow furrows- when he pulls back, he looks down and spots D's soft cock, spurting little streaks of cum.
"Oh, baby," Bro breathes, chest hot and tight with pride. "Look at that."
"Mmmmh, Bro… Bro, please, my- my other-" D begs, trying to tug Bro back in, seemingly completely unaware of- or maybe completely uncaring of- the soft orgasm he's just had.
Bro obliges, ducking his head down and taking D's other nipple into his mouth- and the world dissolves into a blur of warm milk and hot pleasure and D's cries in his ears.
——
Finally properly domesticated, D settles into his new life with a happy ease that brings Bro no small amount of joy. Uncaring of higher goals or most of the outside world, his pretty cow lazes around the apartment and watches TV or plays games, unconcerned with anything but fun, happy things and the ever-present pressure of milk in his chest.
D doesn't hesitate to seek Bro out if he needs milking- oftentimes just plopping into Bro's lap and demanding that Bro suckle. It's adorable- and Bro's gotten used to having tissues within arm's reach at all times. D's cock never does get hard again, but it sure as hell loves to cum when Bro nurses at D's tits.
It's finally the way things should be. The two of them, happy and together, and Bro's not ever gonna let that change.
