Chapter 1: The Exam
On a crisp summer morning, six children were born. All from the same mother. A rare occurance of sextuplets. Their parents were Betas who wanted to start a family despite their low sexual energy or need. It was everyone's dream, get married, have kids, and have a peaceful retirement at the end. Each child was wrapped in a colored cloth and given to the kids. From oldest to youngest, the names were Osomatsu, Karamatsu, Choromatsu, Ichimatsu, Jyushimatsu, and the last born, Todomatsu. They parents were happy beyond measure. They had six healthy, beautiful boys. It was too young to know their natures, so they enjoyed the time they had with their children before that exam came.
In highschool, that exam came. Every young freshmen was taken into a room to be checked. Parents had to consent to this, like a consent sheet for a field trip. Not everyone liked the idea of their children being examined and fondled, but they all went through it once, it wasn't long, and it was important. The line was slowly growing smaller, until it was just the six sons first. Naturally, Osomatsu went first. His was quick, since an alpha could immediately be identified by the knot around the base of his penis, near his pelvis. He was allowed to cover up. Karamatsu was next, once again another alpha. Choromatsu came next, and it seemed he would be the first in the group for the rectal check. Omegas had a special pouch in their bodies, their "womb." It could be found by pressing on the walls for something squishy and easy to slip into. The examiner put on a glove and lubed his fingers before going through the uncomfortable procedure, for both of them. Choromatsu hid his face in the pillow as he was felt around in the inside. The rectal exam came back with a betta. He was allowed to pull his pants up. Ichimatsu was another alpha, he was thankful since he hated watching what happened to his older brother. Jyushimatsu, who was smiling before, had a scared expression. He didn't have that knot, so he was told to lay on the bed and remove his shorts. A new glove was put on and more lube before examining the young boy, who held back his whimpers at the odd, intruding fingers. His rectal exam proved he was an omega, by the finger slipping into something along the deep end of his rectum. Jyushimatsu took deep breaths to collect himself before going back to the brothers waiting for him. The youngest also had to endure the exam, and was confirmed to be an beta. Ever since that day, they had been classified, put in groups, never able yo see their omega brother again. Bettas could attend class with alphas since they can't drive them mad, but omegas had special classes. Classes to prepare them for their future in a safe environment. The only time they saw little Jyushimatsu was at home. When their parents found out they were devastated. A single omega amongst three alphas... It was not good. If he was to slip into heat, he wouldn't be able to stop his savage brothers from reacting on instinct. They bought the young boy pills to take to help this heat, to suppress it so he would not have one. It was all going well, until one day their mom forget to refill the bottle.
Jyushimatsu, now 25, stared at his empty bottle. That's weird. Is he old enough not to need them anymore? That's awesome! He hated taking those pills. They tasted awful. He walked back to the living room with the rest of his brothers to do their shenanigans. His mother was unaware of her error, and she was informed one Saturday morning. The scent flooded the room, the sweet, tempting smell... Jyushimatsu woke up with his thighs covered in a sticky substance that seemed to be leaking from his anus. He reached back to see what was wrong and had to cover his mouth. He was so sensitive, this was his first heat, abnormal for an omega. They should at least have one best before taking suppressants, but their parents didn't want to risk anything. Now Jyushimatsu was absolutely crippled with his heat, if he tried to stand, his apparent erection would rub on his pajama bottoms and make him shake. If he tried to crawl, He rubbed his thighs on his erect unintentionally. He was trapped. And then his brothers woke up. Choromatsu and Todomatsu rose out of bed like normal, but noted the weird smell. It was new. They saw Jyushimatsu's state and immediately realized it was him that was letting off that smell. And a little too late, because their alpha brothers also did.
"OPEN THE DOOR!" Osomatsu roared from the other side of the closed bathroom door, all the alphas were there. They couldn't think straight, they just knew they NEEDED Jyushimatsu. Choromatsu and Todomatsu held their trembling brother as all of this happened. Jyushimatsu sobbed as one slammed the door particularly hard. It would break, his anxieties said. They'll get in, his fears insisted. They'll take you, the truth said. He had the instinct to run, but where could he go? He was now cornered in the bathroom with his betta brothers, who were just as scared as him. They had no idea what was happening with their brothers... But they knew they had to protect Jyushimatsu. It was their brotherly instinct, along with their betta nature. All bettas offered their hands to suffering omegas to keep them sage from alphas, they why they were bred. They would protect Jyushimatsu.
Their parents came home and quickly defused the situation, though their alpha boys didn't want to give up so easily. They were all places in separate rooms to let out their emotions on anything but each other. Jyushimatsu was quickly given pills after Matsuyo went to the store, but the damage was done. Their son was in heat until it decided to end, they couldn't control it. They would keep him safe until it was over...
Chapter 2: Staking Claim.
There was a fault in the beta's defense system, Osomatsu saw that, and took the sweet opportunity.
Jyushimatsu gets claimed and marked, Osomatsu claims his dominance over the rest of his brothers.
Jyushimatsu had been soaking in a bath for the past week. His mom said a cold bath should help with the heats, but it really didn't. All it did was make him cold. There was an upside to all this, he could touch himself without getting messy. Todomatsu told him playing with his leaking back side could help, said he read it on his phone. Jyushimatsu often just stroked his hard cock when he was in the bath, but every now and then his fingers would venture down to his hole as he debated doing it or not. Today he decided to do it, slipping his index finger in. It felt weird, intruding, and uncomfortable, but his trusted his brother when he said it should help. He twisted his finger and rubbed his walls, eventually he started to feel pleasure. It's when he found his prostate is when things were amazing. He felt dizzy, barely paying attention to anything as he finger fucked himself, adding a second finger and a third, only getting louder. It wasn't making it any easier for his brothers and parents. They would guard the doors he was in so their alphas didn't get to him. They knew the three were lurking around, their threatening alpha scent strong in the house. When the fingering started, things became much worse, and his family was just praying it ended soon. What they couldn't avoid began to happen, the alpha's fought. Fought for dominance, fought for the right to claim Jyushimatsu, and just fought because their instincts told them to. For what the betas in the house heard every time, it seemed the eldest wasn't planning on submitting to them. He planned on making it known that he is the top alpha in the house, and the other two were just a thorn in his side. Karamatsu was a tougher brother to fight, both of them lusted for dominance and control, they fought every day. Ichimatsu didn't have too much stamina for fights, so he usually ends up giving in to his dominant brothers. It was clear he wasn't strong enough to dominate them, so he had to be sneaky when he does things, like fighting. He often used the sneak attack method on his brothers, but he was always easily pinned and forced to submit before they start leaving wounds on his body. He didn't want to dirty his clothes with blood.
There was an opportunity and Osomatsu saw it one day. Only Todomatsu was guarding the door, the rest of the betas were out getting stuff for the house. Of all the betas, he's the weakest. Deep down in his heart, he never wanted to hurt his brothers, but right now he's got alpha brain. All that was important was staking his claim and being the top alpha in the house. Fighting only went so far. He was done fighting. He would claim the ripe omega in the house to prove he's on top. By any means necessary.
Jyushimatsu was sitting by the table having a cup of insta-noodles when he heard a fight outside the door. He figured he would be okay, since the previous fights didn't last long, but this one didn't seem to ever last longer then a second. That's when Jyushimatsu caught the musky scent of an alpha leak through the door, and he panicked. He couldn't hear Todomatsu anymore. He tried the first thing that came to mind, jumping out the window, but their parents had the locked tight so his brothers didn't have the same idea. He was done for when the door opened. He was afraid to look. To see who it was that was going to stripe him of his virginity. Every possible answer hurt to think about. It wasn't what he expected, he expended to be pinned in mere seconds and naked the next second. His brother, whichever it was, came behind him and started to sniff on his neck, at his scent gland. The spot he would have to mark if he was to claim dominance. But not yet. Not yet... He placed a hand on his brother's throat and began to lick his neck, running his tongue along that sensitive gland that sent shivers down his little brother's spine. As cruel as he was, he didn't want to hurt Jyushimatsu. He wanted to be as gentle as his brain would let him, but he wouldn't answer to no... His brother has to know, you can't say no to your alpha. Jyushimatsu got a glimpse of the brother doing this when a red covered sleeve started trailing up his shirt. Osomatsu... Why?
"Nii-san, I-I'm scared..." Jyushimatsu tried to reason with his brother as he was stripped and bent over on the table. "Mmr... Don't be scared, Jyushimatsu... Oniichan will take very good care of you. I'll protect you from that trash." Jyushimatsu got more scares by the second when he heard his brother taking off his pants. Why is this happening? Didn't Osomatsu care for him? At this moment, he couldn't tell if it even was his brother anymore. Osomatsu leaned over him and pushed his face into his neck, once again taking in that delicious scent. His brother was so wet, he was sure he didn't need lube, not that he would've. He's too lost in the moment to think of that. He needed to claim, that's what he needed. Not lube. He wasted no more time thrusting into his little brother, making the poor omega squeak in pain and shock at the sudden move. Admittedly, Jyushimatsu thought it felt good. He had massaged his walls many times, he wasn't exactly new to putting things inside him. But this was thicker then his fingers... It rubbed on the good spots so easily. He couldn't help but moan as his brother had his way with him. His heat crippled brain didn't see the problem with the fact that they're brothers, or that he's being raped, it told him it was good. It was good, it felt amazing, especially when Osomatsu sped up and took him wild. He had lost track of how many orgasms his brother gave him, some out of the obvious place, and he gave him the experience of a dry orgasm. He was going crazy. Osomatsu couldn't go much longer, in his core he was still a virgin, he had low endurance. He knew better then to knot his little brother, so when he was ready he simply finished on his back, growling a little as he stroked out every drop. Jyushimatsu was dizzy, he was sweaty and dirty, as dirty as the table he was on. He was in the clouds after his last orgasm, so when he brother was over him again he just assumed he would take him again. He didn't expect him to bite him. That snapped him out of his thoughts. "Nii-san!" Jyushimatsu cried out in pain as his neck was marked for the very first time. It definitely wouldn't be the last either. Osomatsu licked the wound he caused after he was satisfied with how the bite looked. "You're mine, little brother... That trash isn't going to take you from me." Jyushimatsu held his neck, stinging at the cloth coming in contact with open wounds. "I'm bleeding..." "It won't last long." Osomatsu pulled on his pants, ready to show off the new scent that plagued him to his other brothers, but he saw Jyushimatsu's face and that made him stay just a little longer, helping him bandage the wound. He was mad about it being covered, but the bandages would come off eventually. Jyushimatsu will wear his mark like jewelry, he's going to make sure of that. He left his brother on the couch after that, more then ready to find his shitty brothers. They'll be so defeated. He didn't care. He felt on top, that's what mattered.
Chapter 3: Apology.
Jyushimatsu's heat finally comes to an end and Osomatsu can finally realize what he's done. He apologised, but would it be enough?
An apology that can only fix so much.
As expected, the other two alphas were enraged when they smelt Jyushimatsu on their brother. "Bastard." Karamatsu growled, upset he got to Jyushimatsu before him. Ichimatsu raged in silence. Osomatsu laughed and sat on the couch, rubbing under his nose. "Aahhh, It was great. You missed out on the perfect chance to take him." Karamatsu glared at the floor. Damn it, how was he going to compete with that? Osomatsu did the thing that would keep his dominance at the top, took a mate. The other two could only glare at the floor in the mean time.
Later when everyone else came home Jyushimatsu was quickly thrown in the bath to wash off all the disgust from his body. Now that it was over, and he wasn't crippled by heat, Jyushimatsu felt humiliated. He felt dirty, weak, betrayed. After his bath his mother held him close and let him cry on her. She was angry at herself, blamed herself for this. Choromatsu was the first one to actually so something about it, storming to the living room with the alphas in it, two obviously agitated and one exploding with pride. "Osomatsu, how could you?!" Choromatsu screamed when he slid the door open. Osomatsu looked to him. "Eh?" "Don't "EH" me! You know what I'm talking about!" Osomatsu blinked before laughing. "Oh right! Yeah. I remember." Choromatsu was boiling. "How could you?! He's our little brother!" Osomatsu nodded. "Yes yes, I know." "And?! Do you have anything to say for youself?!" Osomatsu rubbed under his nose. "It felt amazing."
Choromatsu couldn't believe he had such shit heads for brothers. Osomatsu had no guilt, no regret in what he did to Jyushimatsu! He almost forgot about it! Who does that?! He would never really understand how his brain worked, but he knew Jyushimatsu was hurt, and that's what he cared about.
Thank every god who listened, Jyushimatsu's heat ended after that horrible day. Despite the pain in his rear, he felt like his normal self again, bubbly, loud, and a little obnoxious. The alphas in the house calmed down after the heat scent wasn't in the house, and the guilt hit Osomatsu like a train. His little brother was off to play baseball with Ichimatsu like always. He laid on the floor and stared at the wall. In the pose that screamed "don't talk to me." How could he do such a thing to his brother, his sweet baby brother who trusted him with his life? He barely remembered the past week, but he remembered what he did to Jyushimatsu clear as day. He had to apologize, but would that even be enough? No. It would never be enough. He left scars on his brother's heart. And his neck... But he knew he had to apologize anyway. Jyushimatsu had to know he regrets it, that he loves him and never wanted to hurt him. Him and Ichimatsu didn't return until sun set, the older of the two exhausted and dragging his feet into the house and really just wanting to sleep. He couldn't remember much about the week either, but like everyone in the house, he knew what happened and felt protective of Jyushimatsu, but what could he do? It was painfully obvious he was barely a fight to his older brother. He still glared at Osomatsu as he was still laying on the floor. He hasn't moved all day. Jyushimatsu changed out of his baseball clothes to his normal clothes, so happy to wear clothes again. He didn't wear clothes much during his heat since he soaked the whole time in the tub. Osomatsu took the chance when he went upstairs to talk to him alone. No one liked it, tried to stop Osomatsu, but he just plowed on through. He at least had the decency to knock. "Jyushimatsu? Hey, I'm coming in." Jyushimatsu was just finishing up putting on his hoodie so he was decent. "Nii-san, you should have came! Me and Ichimatsu managed to get some free food from Chibita on the way home!" Even right now Chibita's oden didn't do anything to take his mind off the guilt, but he has to approach this topic carefully. Jyushimatsu was trying to act like everything was fine and that nothing happened, but that bite mark servers as a reminder. "Ah... Really? Lucky. He'd ever give me any for free." Osomatsu sat on the couch. "Hey, can we talk?" Jyushimatsu felt a spark of anxiety go down his spine, but he didn't say no, sitting with his brother. He sat on the couch and held his knee caps, waiting for his brother to talk, but Osomatsu couldn't find the words to express his guilt. "Jyushimatsu... I'm sorry." It's all he could think to say before he just pulled his brother into a hug. Jyushimatsu was scared for a moment before he realized he was just hugging him. "Osomatsu nii-san, it's o-" Osomatsu snapped at him in his shaky voice. He was trying not to cry. "It's not okay." Jyushimatsu looked down at the couch before slowly wrapping his yellow sleeved arms around his brother, who finally broke down. Jyushimatsu did to. Osomatsu couldn't stop apologizing, and Jyushimatsu couldn't stop hugging him. "I wasn't thinking..." Osomatsu said with disgust. "I couldn't think, my mind was fuzzy... But I mean it when I say that wasn't me..." Jyushimatsu nodded. "I-I know, Osomatsu nii-san..." "How can I make it up to you...?" Jyushimatsu couldn't answer him today. That was fair. Osomatsu didn't expect an answer right away. They got the tension between them calmed down for now, and he hoped it never came back. "Just, for the love of god, don't forget your pills again..." "Way ahead of you, Nii-san."
