Macau hates him.
That's a fact Pete learns quickly after moving into the minor family compound. Even at the hospital, Macau has already begun to despise him. Those first few days, he might've been happy just seeing his hia awake and blissed-out on pain meds, head over heels for Pete, but when it becomes clear that the Omega is going to be part of their family now, his attitude starts to shift. All of a sudden, he hisses whenever Pete enters the room. He furiously grabs his jacket and bag to leave his brother and Pete alone whenever the Omega comes to visit. He refuses to be part of their conversations, ignores Pete's greetings and questions. When Vegas is dismissed from the hospital and Pete arrives to accompany them home, Macau chooses to take the bus rather than ride in the car with them.
It's then that Pete realizes just how much the pup detests him.
"He hasn't adjusted yet. Please, Pete, be patient with him. He's never had an Omega in his life before," Vegas pleads weakly that night when Pete gently wipes his chest down before bed. Macau still hasn't returned home, and he doesn't until way into next morning, with bloodshot eyes, dirty clothes and messed-up hair. He looks like he's slept on the street somewhere.
Pete escapes the tension by slipping into the hallway. From inside the bedroom, he hears them argue.
"Did he spend the night here?"
"He's going to spend a lot of nights here, Macau. Pete is my Omega, you can't—"
"I can! Get rid of him, I don't want him here!"
Macau is screaming in absolute wrath, and Pete feels the sting in his chest harder than before. Vegas has just claimed him as his Omega, and in the same breath Macau has rejected him in the worst way possible. His Alpha sees that boy as his pup – after all, Vegas is the one who has raised Macau – and subsequently, that should be Pete's pup, too. Macau storms out of Vegas' room with a furious snarl on his face, and when he nearly stumbles into Pete, he throws himself back against the wall so quickly it just has to hurt. Breathing hard, chest heaving, Macau stares at the Omega. His eyes are wide with something dark, something frightened. Pete surges forward in instinctive concern, but Macau ducks away with a trained ease no pup his age should possess.
"Get away from me!"
He disappears down the winding hallway faster than Pete could possibly hold him back, but he knows Macau wouldn't have let him in the first place. When he returns to Vegas' side, the Alpha looks at him with tired eyes. It's clear that he's too exhausted to put up with his brother's tantrum right now, and Pete desperately wishes he'd be able to go and calm Macau down so Vegas can stop worrying. He knows how Macau must be feeling – abandoned, alone, having only ever known abuse, deceit and hatred, unfamiliar with love and comfort, and being too scared, too mistrusting to accept it now that it's offered to him.
Pete has been much the same when his grandmother has taken him in after his father died.
The next fight they have is about the pillows and blankets disappearing from the laundry when Pete starts to nest, and it's even worse. That's the fight where Pete ends up sobbing against Vegas' chest – not because Macau has been hurling every insult in the book at him, but because Vegas screamed at Macau to shut up, and that has left the pup speechless, slack-jawed, and with tears running down his face before he has fled the house.
Pete hates it. Hates that he's the reason they fight, hates standing between them. He knows how much Vegas loves Macau, knows how much that boy means to him, and now he's ruining everything. They're finally rid of their father and could be happy, but all Pete does is make Macau miserable with his sole existence in their household.
"Don't cry, doll," Vegas begs as he tries to wipe Pete's tears, "he's just—"
"He's right!" Pete sobs. "I should just get out of your lives, should just leave you alone!"
Vegas almost slaps him at that. What he does instead is chain Pete to their bed by his collar, kneeling on the cold wooden boards. He doesn't let him get up until the Omega is completely soft and pliant again and all talk about leaving has been forgotten.
When Pete's heat hits, Vegas is still too weak to bear more than two rounds of sex before he collapses into the bed, choking on his own blood, clawing at the bandages around his chest. Crimson blotches are blooming on the pristine white of the wound-covers. Medics storm their room when Pete calls for them in panic, and they take Vegas away. One of them stays back to check Pete over. He offers hesitantly to sedate him for his heat, and when the Omega refuses, he tries to convince him. Vegas won't be able to help him through it – why would he want to suffer while his Alpha is away?
Pete's explanations are too personal, so he simply sends everyone away, curls up in his nest, and falls to pieces. It's too much, it's all too much. His Alpha is hurt, his pup rejects him, and he seems to be at fault for all of it. His pussy is aching and hollow without the perfect weight and heat of Vegas' cock, and Pete is sensitive all over. Every brief contact with the fabric of his sheets makes him flinch and cry out helplessly for his Alpha. In vain, of course, but just Vegas' name on his lips makes it all more bearable.
It's the middle of the night when he has finally drifted into a fitful, restless sleep at last – not for long, though.
The door to the bedroom opens, and a thin line of golden light seeps into the darkness. Half-hopeful it might be Vegas returning, Pete lifts his head. The silhouette in the doorframe is blurred from his tears, and badly lit from the light hitting the person's back. They shift uncomfortably, silently, hesitant to enter. When Pete takes a shaky breath to gather his last strength and call his Alpha's name, he's hit with the scent.
The scent of an abandoned, frightened, neglected, hurting pup.
Then, a voice cuts through the daze that has settled on Pete like a smothering blanket of pure agony.
"Mama?"
Oh.
The sound alone makes Pete snap up, eyes widening as they zero in on the boy. Macau's hair is still mussed up from sleep, his scent warm and bitter and so, so full of pain and craving and hunger.
"Macau!" Pete purrs desperately. His arm reaches out over the border of the nest in an inviting gesture. Slowly, Macau steps towards him. He stalls again by the side of the bed, but then he whimpers like an injured little animal and crawls into the warm comfort of Pete's nest. There's no fierceness about him tonight, no flashing fangs, no hateful snarls.
Pete could've cried in relief.
"Hey, my boy," he croons with a sob, "hey, puppy."
Macau is on top of him in an instant, tears dripping down his face as he tucks himself into Pete's arms, lets himself be held and scented and kissed. He's not the defiant, rebellious Alpha anymore he has tried to play over the last few weeks, he's just a pup – lonely, desperate, starving – and who is Pete to deny him? An Omega in heat is either content with an Alpha to breed them, or a pup to cradle and fuss over. Being granted the one, Pete doesn't need the other. He runs his hand through Macau's hair over and over, purring, making all those soft little noises to soothe the poor pup. Even though he's still burning up, the painful emptiness between his legs is long forgotten. Instead, he flinches every time Macau brushes his already sensitive chest. He doesn't let the boy notice, though.
"It's okay, puppy, it's okay. Shhh, don't cry, Mama is here…"
"No!" Macau sobs and shakes his head, eyes squeezed shut. He shoves his forehead against Pete's shoulder, gasping sharply, warm breath caressing the Omega's bare skin. With every new intake of air, he sucks it into his lungs more greedily at the sugary-sweet scent that surrounds them. "I was so mean to you, I was so… so…"
"You were scared, puppy, it's alright. I'm not going to take Vegas from you, and I'm not going to hurt you," Pete tries to reassure him. Tears of his own sting in his eyes from how much his chest hurts, instinct telling him to console and feed the starving pup in his arms like he's supposed to do. "Puppy, calm down, come here, come—"
He tugs Macau closer on reflex, but the pup strains in his arms, tries to dislodge his grip, weakly paws at the Omega's wrist to get it off. It's not like he's trying hard enough. He wants this, Pete can tell, but he's still denying himself.
"No, you have to hate me, you can't—"
With one last, broken little sob, Macau gives in. He surges forward, innate urges and sensitive nose leading him right to where Pete smells sweetest. His lips close around the Omega's nipple and he gives a harsh suck, shoulders shaking from the sudden relief. Pete whines softly and throws his head back. Absolute bliss washes over him as Macau falls into a desperate rhythm. The soft sucking noises that fill the nest are nearly cathartic to the both of them. Pete buries his hand in the boy's hair again, slowly smooths it out, then he bends down to gently kiss the crown of Macau's head.
The pup – his pup – gives him an infinitely loving little noise, like a purr but not quite, and Pete melts. His chest still feels sore and tight, but with every passing second, he relaxes more, eyes sliding shut as he still cradles Macau close to him.
"My good little puppy, such a good boy for Mama," he whispers, running his hand through the boy's sweaty hair. "That was really hard, holding back all this time, hm? It's okay, puppy, I promise. Just relax now, you're safe."
With a shuddering breath, Macau opens his mouth ever so slightly. His lips are glistening like two halves of a pearl and he licks the saliva from them before placing soft, sucking kisses on the Omega's stiff nipple.
"Mama," he whispers, obviously savoring the word like candy on his tongue. "Mama, love you."
Pete smiles through his tears, helplessly enamoured with the boy, with his pup. He guides him back to his nipple, desperate to feel him nurse again. He's too sensitive to be deprived of both the stimulation from his Alpha and his pup right now.
"I love you too, puppy. I love you more than I could ever tell you."
Macau whines a little, but his lips never dislodge from the Omega's nipple as he continues to suck, tongue tracing the sensitive skin over and over. It's all Pete really needs to come. Slick oozes down his inner thighs and into the nest, as hot and thick as syrup. The climax is shallow and gentle, more like rhythmic little pulses of pleasure than the usual crashing waves of it, but it's enough to have him trembling and rocking his hips up. Macau seems to notice, eyes flickering open for a second, but then he settles right back down. The next few times it happens, he doesn't even react anymore. All he's focused on is the absolute relief of getting to be with his Mama, and Pete's voice whispering to him, praising him, assuring him how much he loves him.
When Vegas returns to them a day later, wounds freshly bandaged and a little recovered, he finds Pete leaning against the headboard of their bed, gently cooing at Macau while the pup nurses. All Vegas does is inhale sharply at the sight before he crawls into bed with them. He spoons up behind his little brother and strokes his quivering flank, his hips, his chest, and finally also his cheek.
"Hia," Macau purrs around Pete's nipple. The vibrations make the Omega shiver with pleasure.
"Are you finally being nice to Pete?" Vegas asks quietly and combs Macau's hair out of his face. "That's my pup. Does it feel good?"
Frantically nodding, the pup shuffles closer to Pete as if he's afraid Vegas might take him away or tell him to get out, but the Alpha just kisses his forehead. Then, he leans up to hungrily devour Pete's lips, who barely even has time to moan before a tongue already pries his mouth open and slips inside, fucking him deep and hard to the point of the Omega simply blanking out from how wet it makes him – the combined sensations of his Alpha's kiss and his pup's nursing. Vegas fucks him like that. It's slower than they're used to, for one because the Alpha tries not to open his wounds again, and also because they don't want to disturb their pup. Macau falls asleep with his cheek still pressed to Pete's chest, and Vegas settles down beside him when Pete is starting to pass out between the two of them.
That's the tipping point they've all needed, apparently.
Pete's heat ebbs away, but Macau stays clingy like a toddler. As standoffish as he's been before, as needy is he now. He crawls into bed between Pete and Vegas at night, refuses to stay in his own room. He's on summer break, and spending his days at home means he can follow Pete around like a lost stray all day. At seemingly random, he will shoot up from whatever he's been doing – watching TV or playing on his computer or reading a book – to throw himself at Pete instead, insistently shoving his shirt up to mouth at his nipples before latching on with a weak, desperate pleading noise.
Vegas finds them like that in the kitchen one night: Pete leaning against the counter, head thrown back while Macau nurses, eyes closed in pure bliss.
"Oh, pup, what are we supposed to do with you?" the Alpha sighs and runs his hand down the length of Macau's back. Then, he reaches up to stroke the Omega's face. "Pete, if it gets too much—"
Before he can even come close to touching Pete, Macau grips his wrist so tightly Vegas hisses in pain. Without ever having taken his mouth off of Pete's chest, the pup glowers at him in pure, fearful rage. Only for a second, though – then, he turns his gaze up at the Omega. His hand that isn't keeping Vegas away from Pete is gently kneading at the Omega's chest, almost like a kitten. Pete moans softly and grips Macau's neck tighter. It feels so good to have his little boy this close. Even after his heat, his chest and nipples have remained so sensitive.
"Mama!" Macau whimpers, his tone a soft plea for Pete to not let him go.
"It's alright, pup, relax," Pete hushes him in an instant and gives Vegas a scowl while he cradles his pup closer. "Vegas, he needs this. I need this. Let him nurse."
The Alpha regards him thoughtfully for a moment, then he nods. Over the next few days, he makes sure to stock up on silk shirts for Pete that won't irritate his swollen, puffy nipples, and can be easily unbuttoned – and he starts to train Macau into not simply tearing through Pete's clothes whenever the need to suckle overcomes him. Instead, he brings Macau to the living room one evening where Pete is curled up on the couch with a book propped up against his thighs, reading. He discards his readings when he sees his mate and pup enter, although his welcoming smile fades a little at the sight of Macau. The pup is tense and nearly shivering.
"Pup, what's wrong?" he asks worriedly and holds out his arms, but Macau only looks up at Vegas with an unsure glance.
"Go ahead," Vegas mutters and nudges him, one hand on his shoulder. "Be a good, big boy for Mama and Papa."
"Mama," Macau whines, eyes zeroing in on Pete's chest, "Mama, please— I want… I want to nurse, please."
Oh.
Of course they've spent entire days now acting on Macau's new instincts, but this is the first time Pete actually hears the pup's voice his desires. It sends shivers down his spine, and still, he tries to rein himself in. Macau is doing something so very brave for him, he can't let it go just like this. With a soft coo, Pete reaches up and begins to unbutton his shirt.
"Of course, puppy, come here," he coaxes, a little shaky with need. Having been given permission, Macau is instantly on the couch with him. Pete can feel his pussy slicking up when the boy climbs into his lap, and his head rolls back against the backrest in quiet bliss once Macau latches on and starts to suck. Pete threads one hand through his hair over and over, trying to steady his own trembling. Maybe it's because of how real it feels with Macau telling him what he wants, but somehow, he's even more sensitive today. "Such a good boy, 'Cau, my sweet pup."
Macau whimpers softly in response, eyes already closed as he completely relaxes into Pete's arms. Vegas sits beside them and coils one arm around them both. His lips press tightly onto the Omega's, parting them for his tongue while he runs his fingertips down Macau's spine in long, teasing lines.
"You know, I can smell you," Vegas mutters in sharp amusement when he pulls back ever so slightly, and Pete flushes. "Every time he comes to nurse, you get dripping wet, and sometimes you even come just from him sucking on your nipples. Does it feel that good? You want your pup to fuck you while he's nursing?"
"Vegas—" Pete moans, writhing slightly when he feels the Alpha's hand sliding down to his chest as well, thumb rubbing over his other nipple, caressing the sensitive nerves insistently, massaging the tender skin around it.
"It's okay, shhh. I want you both to feel good," Vegas soothes him, and silences Pete back down with another kiss.
Pete doesn't know why his breath stutters all of a sudden as soon as their lips connect, but there's a sudden release of tension inside his body at the reassurance that it's okay, and Macau starts to purr frantically against his chest. His sucks get harder, almost painful, and Pete mewls softly in shock at the new eagerness.
"Ahh— 'Cau, puppy, be gentle, that… that hurts!"
His voice tapers off into a needy moan when Macau only buries himself tighter against his chest, hungrily suckling on his nipple. It's only when he's completely breathless that he pulls back, licking his lips, and a thin line of milk runs down his chin. Pete grips his hair tighter and pulls him back down, the lack of suction just as bad as the faint ache of nursing itself. Macau doesn't let himself be coaxed twice – he's back at it in an instant, more content and purring even louder than before.
Vegas laughs softly above them. His voice is tense with arousal when he begins to press hot, open-mouthed kisses against Pete's throat.
"You really are the perfect Omega, aren't you?" he whispers, out of breath already. "Look at you, taking care of our pup so well. How does his milk taste, 'Cau?"
The pup just hums, unwilling to release his newfound bliss just to answer a trivial question. He drinks like he's absolutely parched, and Pete has to clench his thighs to stop the steady leaking of slick into his panties. His body is alight with hypersensitivity, so very desperate to feed the apparently starving pup in his arms that he really has started producing milk just for Macau. The boy wriggles closer to him, eyes closed, completely at ease, but the sweet scent of his absolute contentment is mixed with heavy, dark arousal.
Vegas helps Macau undress very slowly, careful to let him continue drinking. Only once, when Pete has the boy switching sides, do they stall for a second longer to get his shirt off too. It's easy enough to undo Pete's belt and slide his slacks and underwear down. Vegas huffs in amusement when he sees the thick strings of slick stretching between the Omega's thighs already.
"God, you must be so needy, aren't you, pet? Don't worry, we'll get him to fuck you in no time."
Only when they're both comfortably settled on the couch does Vegas dip one hand down to cup Pete's cunt, gently stroking it with his open palm before he coils his slicked-up hand around Macau's hard cock. The young Alpha jolts and pulls off of the Omega's chest for a second. Vegas shushes him softly and brings his hand up, rubbing some of Pete's slick onto his puffy nipple. The honey-sweet scent coaxes Macau right back. The Omega shudders softly at how eagerly Macau laps up his slick before he sucks again, swallowing audibly. With Pete stroking the pup's hair very gently to soothe him back down, Macau relaxes into his brother's touch again. His hips roll forward, thrusting into the tight grip Vegas has on him, and the older Alpha laughs softly as he guides Macau between Pete's legs. Still rubbing the boy's cock, he sets the tip of it against the Omega's pussy, and like on instinct, Macau jolts forward. Pete gasps in shocked pleasure, hand clawing Macau's hair at the sensation of the boy thrusting into him.
"Mama!" the boy moans in response, feverish and weak as he licks a trail of milk that has dribbled down Pete's chest. Vegas lets go of him at last, instead reaching up to wipe his slick-covered fingers on Pete's nipple again. Macau greedily licks the sugary liquid up alongside the milk that drips down the Omega's chest, then he slams his cock all the way into the hot, dripping wet tightness of Pete's cunt. He's shaking, and the Omega buries his face in the boy's hair with a whine of his own at the sensation of finally being filled.
"It's— God, puppy, it's alright, shhh, it's okay," he whispers, over and over, just frantically stroking Macau's naked back. "It's okay, there you go. My good puppy, my perfect little pup. You're being so good for Mama, so good—"
He can tell how much Macau needs this, because his soft sucking loses its rhythm completely, his slender hips stutter as he grinds deeper into Pete. It's completely instinctual, nothing even close to technique is present in the sharp movements – all he wants is to get his cock as deep into his Mama as humanly possible. Vegas keeps stroking his back, his sides, his arm, and he feels his older brother settling against his back so he can kiss Pete. The soft sounds of their lips meeting make Macau shudder. He gives a particularly hard suck, smug with the knowledge that it makes Pete moan so Vegas can easily slip his tongue into the Omega's mouth.
"Do you like this?" Vegas breathes against Pete's kiss-swollen lips. "What a good little Omega you are for me and Macau. You like to know you could be getting pregnant from your pup while he's nursing?"
It sounds heavenly filthy the way he says it, and Pete gasps as his cheeks flush.
"Vegas—"
"Hm… Wonder if you'd have enough milk for him and another pup. And for me," his Alpha continues, and Pete feels his muscles ache from how hard he arches his back at the thought.
Macau tightens his grip on him in turn, possessively jealous about just the prospect of having to share his Mama with anyone that isn't Vegas. He's only just gotten him, he's not letting go just yet.
"Papa is teasing," Pete mutters, glares daggers at his Alpha. "Shh, puppy, Mama is all yours. Drink up now, I want you to feel good."
"You always make me feel good, Mama," Macau mutters around a soft trickle of milk that escapes from the corner of his lips. The pup is bliss-drunk and smelling so, so sweet, Pete just wants to curl up around him and hoard him to himself forever.
They're all more at ease than ever, with Vegas gently stroking his mate's and brother's hair in exchange, and Macau gently rolling his hips against Pete's as he nurses. Pete is dozing while the tension in his chest finally eases with every gentle suck from the pup, until Macau is sated and quiet against his chest. He still traces the Omega's nipple with his tongue from time to time just to hear Pete whimper, but otherwise, the living room is quiet. Only once, when Macau comes with a soft noise of pleasure, Pete tenses a little, pussy clenching around the young Alpha's cock and the heat spilling inside him. Macau settles back down with a snuffle and nuzzles into his neck.
"You taste so good, Mama. Like milk and honey," he mutters softly, lips pressed to the side of Pete's neck. They're still smeared with milk and slick. "Love you."
"Mm… love you too, puppy," Pete replies under his breath and noses into the boy's beautiful dark hair. "Love you more than anything."
