“On your knees.”
Rin glared at his brother, knowing what was about to come but refusing to go down without a fight. He had expected this - for his brother to seek him out after a match - but some of him had hoped that Sae would just leave him be and let him reflect on the match in peace.
Honestly, it’s the naive part of him that he hasn’t quite destroyed yet that thinks these wishful thoughts. He should have known better than to expect that Sae will ever give him peace. Even in the time that he’d been cold and distant, the thought of his brother had always weighed heavy on Rin’s mind, pushing him beyond his limits.
“You think that just because you won against me, you can forget about me being your alpha? You and I both know it was a fluke, so get on your knees ,” Sae commands.
Rin gasps, not expecting his brother to use his alpha voice on him. It had been quite a while, and his brother often only used it accidentally in the field when they were both still on the same team. There was once a time when Sae only used his alpha voice on Rin to ground him to reality when Rin got a little too lost in his head, but memories of these times were practically nonexistent now to both brothers.
Sae narrows his eyes and Rin’s inner omega howls, saddened by the fact that he displeased his alpha. Rin hisses internally, telling the omega side of him to shut the fuck up; nonetheless, he slowly gets on his knees, but maintains eye contact with Sae, giving him the nastiest glare he could muster.
“That’s right,” Sae says, “that’s exactly where you belong. You know what to do now.”
They were in Sae’s hotel room right now, and the only reason Rin was because he’d been forced to by stupid Ego and stupid nii-san. Although Rin belongs to Blue Lock now and the team had just defeated a team Sae was in, Ego cannot just simply ignore that Sae is Rin’s alpha legally. The redhead man currently sits on the couch, legs spread, and Rin kneels between his legs. Then, slowly, Rin unzips his brother’s pants. Both are quiet and the tension in the room slowly grows.
Rin’s hands are shaking, so he takes a deep breath to calm himself down, but in doing so he inhaled his brother’s musky scent, head immediately going foggy. His inner omega grew stronger and more persistent as he pulls down Sae’s underwear to take out his cock. As always, it’s clean and it looks magnificent, trimmed pubes brushing against the side of Rin’s hand as he gently grips the base of his brother’s huge dick.
Sae lets out a soft grunt, and Rin’s eyelashes flutter at the sound. Sae’s eyebrows raise. “Well? What are you waiting for? Has your performance with sex gotten sloppy like your performance on the field?”
Rin’s inner omega whimpers, but Rin growls at his alpha before gripping the cock tighter and taking the cockhead into his mouth. Sae inhales sharply as Rin lets out a soft moan. He works his tongue around the head, making sure to lick at the slit, before moving his head up and down, his right hand stroking the base of his brother’s cock while his left hand supports him on the floor. He can feel himself getting wetter and wetter, but his mind is focused on giving maximum pleasure to his alpha using his mouth.
Stupid Sae. Rin will show him how amazing he is. He’s the best fucking omega in the world and none of the other omegas Sae probably fucks will ever compare to him.
Because you were made for him, a tiny voice inside his head whispers, but he dismisses it, focusing instead on his breathing so he can deepthroat the cock he was sucking.
“ Fuck,” Sae curses. Rin whines, because that one word growled out by the alpha (his alpha) was enough to make Rin almost cum.
Sae puts both his hands on Rin’s hair and lightly grips it, then begins fucking his younger brother's mouth. Rin relaxes his throat as his brother fucks his face, knowing better than to reach down and rub his clit. A part of him wants to be a brat, to disobey so Sae can punish him, but for some reason, he doesn’t have it in him to do that today. So, he flutters his eyes close and focuses on his breathing. His hands rest on top of his brother’s thighs and the redhead's pubic hair tickles Rin’s nose slightly every time he comes to contact with it.
Then, Sae shoves his whole dick inside the younger’s mouth. Rin struggled for a bit but eventually tried to even out his breathing, throat contracting around the alpha’s dick. His nose is buried in his brother's pubes and with each inhale he gets intoxicated by his brother's musk. He stayed like that for a moment, cockwarming his brother before Sae pulls him off his cock entirely, harshly shoving Rin to the side that he loses his balance for a bit. Sae starts taking off his pants and underwear completely, and without Sae even saying anything, Rin starts to strip as well.
“What a well-trained slut,” Sae sneers.
“Fuck you,” Rin spits, and Sae’s face darkens. So his little brother’s bratty nature still hasn’t changed, huh. Well, Sae already expected a fight. Although he did make sure to train Rin well, the younger still has a needy and stubborn nature that causes him to be a bratty little thing. It’s probably because he spoiled the younger just a tad bit too much, back when he didn’t know how to control his bratty omega brother yet.
When Rin had his first heat, their parents were out of the house and Sae felt his alpha react to his brother’s omega. In society, mating between siblings wasn’t common, but it wasn’t looked down upon. Historically, alphas and omegas did mate with their siblings for procreation and survival, but as the population grew, people wanted to mate with other people whom they didn’t grow up with under the same house. So, when their parents came home to their sons naked and asleep, the smell of sex permeating the air, the two boys only received a lecture on how to safely have sex. Their mother, the alpha of the family, had pulled Sae aside that same night to instruct him to train Rin well and to protect him.
And train him he did. Rin’s sex drive had been on the higher side. After games, while Sae would crave to have a warm bath and relax, Rin would pounce on him. More often than not, Sae would have to fuck the energy out of him so they could both actually sleep undisturbed.
This particular routine was likely why Rin had gotten his attention after the match, forcing Sae to get Rin inside his hotel room before he finds another alpha to fuck. Shit, the thought of Rin already having done it with someone else in Blue Lock annoys the hell out of him.
Sae clicks his tongue and looks down at his already naked brother. The redhead still had his white button-down on, but the other was completely bare. Sae rakes his eyes over Rin’s figure. From his beautiful, defiant eyes to his tits and swollen nipples to his slutty, tiny waist to his shaved pussy… Sae’s annoyance grows. He doesn’t smell another alpha’s sex pheromones on Rin but the thought of Rin shaving his pussy and preparing himself for another alpha annoys the shit out of him. Hell, just the thought of another person seeing Rin this way makes the ugly, alpha part of him rear its head. So, he slaps Rin, and Rin gasps, pussy gushing out some slick at the action. He flushes in embarrassment and Sae smirks.
“Sit on the couch,” Sae orders and Rin complies. Once seated, it was Sae’s turn to kneel in front of him, forcefully spreading his legs open. The elder felt it was a good time as any to shame his brother further.
“What the fuck is this, huh? Are you really a whore now, Rin? Do you fuck your teammates after every match? Shit, do you enjoy shaving and getting your pretty little pussy all prepped for those brats to fuck? Hm?”
Rin mewls, getting wetter and wetter by the second.
Sae licks a fat stripe from his brother’s hole all the way to his clit, savoring Rin’s juices. “Tastes so good, little brother. But you haven’t answered me yet.” He roughly pinches Rin’s clit and the omega cries out. “Do you or do you not fuck those brats, Rin?”
Rin tearfully glares at his brother, another gush of slick dripping down from his hole. “How the fuck can I fuck them when you’ve already ruined me for anybody else you shitty older brother?”
Sae inwardly smiles at that. He may not look like it, but he’s very possessive over the very few things he owns. And that includes Rin.
"Good boy.”
And with that, he starts eating out Rin’s pussy, flicking his clit with his tongue and sucking. After a while, he adds his fingers, lightly tracing his brother’s fat pussy lips before inserting two of his fingers all at once.
“Ahh~ Hnggg . . . Fuck me already,” Rin whines.
“Tsk, so demanding.”
Sae isn’t in a rush. He knew that the Blue Lock players would get a short break, and he wouldn’t be due to fly back to Spain soon, so he could just keep fucking his brother for days if he wanted to. And hell, does he want to.
Sae hadn’t tasted such good pussy in so long. He’d fucked a few omegas in Spain, but no one even comes close to his brother. He closes his mouth on the clit, closing his eyes to savor it. Fuck, his brother’s fat pussy lips taste so good. His tongue doesn’t stop moving, giving his brother the pleasure he deserves.
The elder then inserts a third finger while his tongue quickly flicks Rin’s clit over and over. He began pumping his fingers in and out at a fast pace as well, and soon enough the younger was trembling.
“I’m- I’m gonna- Oh fuck, ah, ah, ahhhhh~”
Rin squirted and Sae moved his face away, just so that his brother’s squirt would hit him directly in the face. Some of the juices got near to his cheeks and lips though, so he brought his tongue out to taste it. As expected, his brother is as delicious as always. Sae could have sworn that Rin’s juices contained some form of aphrodisiac because once he gets a taste, he could go on for hours and hours as if he were in his rut.
Sae clicked his tongue and slapped Rin’s pussy, fingers hitting his fat clit directly causing Rin to jolt and gasp. The elder comes up and repositions Rin on the couch, hands circling around the younger’s ankles so his feet are high up in the air, legs spread wide and pussy almost facing the ceiling so Sae can easily fuck him.
The redhead lets go of one ankle and Rin keeps it in the air. Sae strokes his cock, already an angry red color then slaps his brother’s pussy with it a few times. Rin whines, mouth open wide and Sae takes that opportunity to spit in his mouth.
“Ahh~” Rin moans.
Truly a fucking slut, Sae thinks. Grabs his brother's cheeks with one hand and spits a larger glob of saliva inside.
“Swallow it,” Sae commands. “Before I fuck you.”
Tears well up in Rin’s eyes in humiliation but he swallows. Sae smirks, feeling Rin’s mind about to break.
Rin swallows.
“Good boy.”
And with that, he shoves his large cock inside his brother’s weeping pussy in one go. Rin cries out, legs spread impossibly wider because of the huge intrusion to his insides.
“‘S big- ‘s too big. I c-can’tttt ah, ah, ugh fuck~”
Rin’s eyes turn glassy as he comes just from his big brother inserting his cock.
“You fucking bitch. I can’t believe how sensitive you’ve become. I didn’t train you to be this slutty, did I?” With a steady rhythm, Sae thrust slowly but harshly. “Is this just how you are? Even if I don’t train or supervise you, you’re still a slutty omega who becomes brain-dead at the slight whiff of cock.”
“Nii-chan~ Nii-chan ‘s too much~” Rin gasps out.
Sae gets annoyed. He’d barely even started. Suddenly, he grips both of Rin’s ankles again to get them to steady and uses it as leverage to fuck his brother into the couch.
“Oh, oh, oh, fuuuuck nii-chan noooo~ ♡”
“I’m so fucking mad right now, Rin. Do you know why? Because other men have seen - what’s - mine,” Sae punctuates his last words with harsh deep thrusts that threaten to open Rin’s cervix to the intrusive cock.
Rin had been too young before, so Sae didn’t go all the way, but now Sae might actually enter his brother’s womb for the first time ever. The thought sends him and his alpha into overdrive and he lets go of the omega’s ankles to grip his waist instead.
“Fuck, do you feel that? My cock is about to enter your womb. Do you like that nii-chan’s dick is making out with your forbidden hole right now?”
“Yesh~♡” Rin moans, keeping his legs at either side of his brother’s arms, already so out of it. “Kish me alpha, kishhhh~♡”
Sae scoffs and readjusts, not stopping his thrusts as he kisses Rin, wasting no time in shoving his tongue inside the younger’s mouth. The snap of his hips continues until he finally feels it. His repeated battering of his baby brother’s womb is finally paying off.
Sae feels the tiny opening loosen, little by little. He stops kissing Rin, noting the fucked out face his stoic brother is making. His hands grip the younger’s waist tight, definitely making bruises that’ll last for days. He keeps fucking Rin into the couch, growling because he knows he’s near. The elder slaps Rin’s clit to stimulate him more and Rin cries out.
Then, his cockhead pops inside, and Sae stills to savor it, letting out a low, deep moan. He’s inside his baby brother’s forbidden and sacred area. He’s inside the place where his future child will be growing in someday. Sae pulls back, ready to ruin his baby brother completely.
“You’re gonna lose your virginity to me a second time, don’t you think so? I’m inside your womb Rin. Don’t you feel ashamed? You’re so young but you’re taking cock like a well-trained prostitute. Hm? Look at you, so good at taking my cock. Fuck, should I just chain you here? Keep you as my sex slave? Breed you so you’ll never feel empty again?”
“Ohhh~ ♡ Please breed me nii-chan~ Give me your babies~♡”
“Fuck,” Sae growls, fully bending down to have his brother in a mating press. Thank fuck for the larger couch this hotel room has.
Rin bends easily, and he whines at the change in angle of the cock inside of him. His flexibility turns Sae on even more. “I’m gonna fucking breed you every chance I get. You’ll never be empty. You’ll always be full, carrying both my seed in your pussy and my child in your womb. I’m gonna fuck you every day, you fucking bitch. Shit.”
Sae’s thrusts are almost punishing, and Rin once again squirted because of his brother’s words. The tangy liquid and smooth slick were all over the two brothers, but neither cared. Rin didn’t even have the right mind to form a coherent thought right now. His brain was just filled with the need to take his brother’s cock and be bred. His senses were overloaded with pleasure and there was nothing he could do but cum and squirt as his brother violated his insides, quite possibly rearranging his guts.
Sae’s hips stuttered and his thrusts grew harsher and more erratic. Then finally, finally, he came, shooting his sperm inside his brother’s fertile womb.
Both brothers were breathing harshly, tired from the sex. Rin’s eyes started growing shut as his brother pulled out. He could feel the liquids, both slick and cum, gushing out of his pussy. He tried to clench to keep it in but he was simply too tired. Just when he was about to drift to sleep, his brother speaks.
“What are you doing? I’m not done with you yet,” Sae growls as he flips Rin over so he’s laying face down on the arm of the couch, ass and pussy presented to his brother, clit rubbing on the fabric of the couch.
Sae reinserts his cock and Rin screams from the oversensitivity and pleasure.
This was going to be a long break.
