He knew he shouldn’t be doing this. He knew he was risking it all the moment he decided to step into Ortho’s room that night. The only sounds present were the gentle snores emitting from the owner of the room. As he slipped under the covers next to him and pulled the younger close, guilt flowed through his veins.
I shouldn’t be doing this, I shouldn’t be doing this, I shouldn’t be doing this.
Idia Shroud’s mind wailed yet his body wouldn’t listen. His hands snaked across Ortho’s smaller body, tracing every curve and dip underneath his jacket. Earlier that day, Ortho had asked to borrow his jacket and hadn’t returned it since. Not that Idia minded, he looked absolutely adorable swimming in it. Because of how big it was, the younger neglected to wear anything underneath besides his boxers. Idia knew this because earlier he got quite a nice flash when Ortho dropped his gaming controller and bent over to pick it up right next to him.
Such a tease. He was practically begging for this.
His inner demons cooed to him, which instantly made Idia freeze up. If this was some sick attempt at his body trying to rationalize this behavior it only made him feel even worse. Still, he couldn’t stop himself even if he tried. It was as if he was a playable character in a game, and someone else was at the controller. His hands continued their venture, eventually making their way down to the very boxers he caught a glimpse of earlier. Silky, soft, and dotted with patterns of aquamarine and pink demons against a deeper blue backdrop. They hugged the younger Shroud’s legs, giving away to the perfect mold of his ass. Idia couldn’t resist grabbing onto it and squeezing gently. A low murmur and a slight shift from Ortho caused the older Shroud to stop what he was doing. After a few long moments, Idia let out a breath he hadn’t realized he had been holding. Still asleep, continue. And so he obeyed the inner demon’s call.
As much as he’d love to prolong this venture, he knew Ortho could wake up at any moment. Carefully slipping down his adorable boxers, Idia peered over Ortho’s shoulder to gaze at the treasure he had been seeking. “Fuck..”, he couldn’t help but whipser aloud. Idia had only ever seen it when they were both younger. They used to see each other naked and bathe together all the time. Though, as they grew older those times grew less and less and eventually they both learned of the taboos society had against nudity and the embarrassment of it got ingrained into the two. Ortho’s cunt was beautiful, to say the least. A lot fatter than he remembered, and it was decorated with the same wisps of blue that were atop his head. Idia’s cock was straining at this point in his own boxers, a wet spot already forming from how much he was leaking. Idia’s hand trembled as he pulled out his erection, lining it up right underneath Ortho’s folds.
Am I really doing this? Am I really?
He paused. Every inch of him was screaming to stop. He couldn’t do this, he made a promise that he’d protect Ortho no matter what. Yet, here he was about to break that very promise and violate his… his…
Idia shook his head. It’s fine, everything will be fine. I just need to do this quickly so I can stop thinking about him and move on with my life. Carefully, he hiked the younger’s leg up a little to give him enough access. Then, he began gently thrusting his cock between those fat folds. Idia had to push his face into Ortho’s shoulder to muffle his own noises, this was already too much for him. “‘M sorry, Ortho, ‘m sorry Ortho,” Idia kept whimpering. The only response he got in return were tender snores and murmurs. Despite Idia telling himself this would be a one time thing and he’d move on from it all, it was becoming increasingly clear that wasn’t going to happen. The feeling of Ortho’s cunt rubbing against his own dick was addicting. The way its huge lips dragged against him and the tickle of his pussy hairs was driving him insane. A warm liquid began to coat Idia’s cock and he realized the younger’s pussy was starting to get wet.
Without a second thought, Idia dipped his fingers into Ortho’s warmth. He examined the slick between his fingers under the low, cerulean light of his hair. He popped the digits into his mouth. Delectable. His mind felt numb, and his body was but a puppet being led by some shadow master. There was no going back, he needed more. The older Shroud’s thrusts began to quicken, and began to get sloppier. Idia knew he had to be careful, he had to be quiet, but with every contact against Ortho’s warm cunt he felt like he was losing his sanity. He pulled his younger brother closer, tighter, and his bony hands found their way crawling beneath the jacket he had on. The realization that Ortho didn’t even have a shirt on underneath made Idia’s thrusts falter a little. What a little fucking slut. The thought panged in his head, and not a lick of guilt was even felt for that one. All it took was his cute little brother’s pretty pussy for Idia’s morality and reason to shoot out the window. Maybe he really was just a freak like everyone in school called him behind his back. A freak that couldn’t control his sick urges.
He panted and groaned into Ortho’s shoulder, his hands touching every inch of skin he could. Unlike Idia, Ortho did have a little more weight and muscle to him. Still, he was so small, so frail, untouched by the evils of the world. And his pervert of an older brother was going to ruin it all with his sinful touch. Eventually, his hands found their way towards Ortho’s perky nipples. He wished he could suck them right now. Oh, he could just imagine it now. Ortho splayed out on his back, gasping and crying out as Idia sucked on one and twisted the other. His sweet little voice, begging for more. To be touched, to be cared for, to “Please, Nii-chan! Please make me cum!” Idia’s head spun, he thought he was going to pass out. His cock was leaking copious amounts of pre-cum at this point. Fuck, he wasn’t gonna last like this. There was one last thing Idia wanted to do before he called it a night, blew his load, and moved on from these sick desires. Because he would very much be moving on from all this and never thinking of it again. Totally.
He ceased his now near manic thrusting and took his cock in hand. Feeling around a bit, Idia found exactly what he was looking for. The tip of his erection kissed Ortho’s puckered lips opening down below. Among the many strange afflictions the Shroud family curse put onto its victims, the strangest had to be self lubrication. Idia’s father had explained it to me in great detail when he was given “The Talk” but such details were lost on Idia’s wild mind right now. In short though, self lubrication occurred whenever intercourse was initiated so sexual intercourse could be done safely without ever needing any lube. Still though, he knew Ortho would be feeling sore come the morning. He pressed past those luscious lips till he was buried halfway in. His body was trembling. Ortho, unsurprisingly, was quite tight and it felt like his own dick would be squeezed off. Yet, it was the most wonderful feeling Idia had ever experienced in his little shut-in life. No toy had ever come close to what he was feeling right now. He pushed until his cock was fully sheathed inside, balls gently pressed against Ortho’s backside.
Idia needed a minute, he felt like he was going to cum right then and there if he didn’t take a pause. He buried his face into Ortho’s shoulder again and closed his eyes, waiting for his own breathing to calm and for his younger brother’s cunt to adjust to the huge intrusion currently throbbing inside of it. Unfortunately for Idia, he wasn’t quite aware of how loud he had been nor how violent his own trembles were. But, somebody else was gradually becoming aware of it.
“Nii-chan..? Is that you? What are you-” the soft, sleepy voice was cut with a large yawn, “-mmm doing?”.
The Ignihyde dorm leader froze. Surely he must have been hearing things, his own conscience now coming to haunt him with the voice of his own dear brother! He stayed still, quiet so he could confirm it was all in his head. The bundle of blue flames moved next to him, trying to turn around to look at him. “Hey, Nii-chan?”. Yeah that was definitely coming from the real world and not from his mind. He couldn’t move. Every muscle in his body felt like it was covered in thick layers of ice and frost that his own flames couldn’t melt. Even if he could, he didn’t want to. Idia knew what was coming and he couldn’t bring himself to look into the eyes staring back at him that would be filled with horror. Maybe if he just stayed completely still forever time would just simply freeze along with him. That was his plan, except his body had other ideas. His cock gave a violent throb, still buried within the depths of Ortho’s cunt. Some sick part of him actually enjoyed this.
Ortho had been oblivious to it before, since he was still half asleep and could barely tell what his surroundings were. The throb, though, felt clearly in a very unnatural spot. The younger Shroud jumped up, trying to inspect where it had come from. Large, yellow eyes grew somehow larger at the sight of the two conjoined in ways they were never intended to be. Long moments passed of held breaths, Ortho staring below and Idia staring at him. After what felt like centuries, Ortho finally turned towards his brother, shock spelled clearly across his little face. Idia didn’t want to look him in the eye, but he couldn’t look away. This was it. It was over. His promise to protect his little brother was torn asunder. All those years spent together, all the trust that had been built, gone. Any second now Ortho was going to run away from him and report him to the NRC staff and their parents for raping him. It was all his fault, so there wasn’t any point fighting it. He couldn’t keep control of his own sick perversions and now his poor little brother would forever be scarred with-
“Oh Nii-chan, you’re such a sicko~”
Yes, everyone at Night Raven College would find out he’s a raging sicko and- wait what? Idia blinked furiously, coming back to the reality before him. The look of horror and disgust was nowhere present on his brother’s face. Instead, what stared back were hooded eyes and a sly smile across his blue lips. “I knew eventually you’d come out about it one way or another, just didn’t think it’d be like this. I ain’t complaining though~” Ortho purred out the last part and lightly tickled his fingers against the bit of Idia’s cock that peeked out of his vagina. Now it was Idia’s time to jump up, reality OFFICIALLY officially kicking in for him. “I-I-I, um, Ortho I, uh, I just, I was just, I-I’m sorry I-I didn’t-” whatever he was trying to say wouldn’t make it past his lips. Tears were welling up quickly in his eyes and he was just about to start sobbing before Ortho shushed him. “Nii-chan, I’m not mad at you, silly! I’ve kind of known for a long time. Everytime I’m around you get all flustered and awkward, well more awkward than usual, and your hair flashes pink. You’re reaaalllyyy bad at hiding crushes, you know? Also, I miiighttt of looked through your search history on a few occasions.”.
Ortho turned around as much as he could and planted a kiss against the other’s pale face. “Besides, I’ve had a thing for you too. I wanted to wait to see how long it took for my older brother to confess. Surprisingly, you did it in less time than I expected, and in a way that feels straight out of those pornos you play.” It was true, this felt straight out of some porn visual novel where things just perfectly end up this way. Whatever, Idia was not about to start questioning the realism of sexual visual novels. He already was having a difficult time processing everything being dumped onto him right now. “Niiii-channnn, quit spacing out and thinking so hard about it. We can talk about it more later, okay? You came here to fuck me, so why not finish that first?” Idia sputtered, “O-Ortho, you shouldn’t be saying those kinds of things! T-they’re dirty.” Suddenly, a small hand gripped Idia by the shirt collar and pulled him close until he could feel a warm breath on his pointed ear. “Oh you’re one to talk, you pervert. Are you really going to tell me that when you have your cock all the way up my pussy?” Ortho's voice hissed into his ear.
Hearing his little brother sound so authoritarian did something to Idia deep inside. He never once thought if he was dominant or submissive, but just hearing that voice made him want to obey whatever Ortho told him. “N-no, ‘m sorry,” he looked away shyly. “Good boy, now how about you get back to fucking my cunt, hmm?” Ortho smirked as he felt another hard throb inside from that. “O-okay,” Idia murmured and began to slowly pull his cock out. “Thaaaatttt’s it, c’mon you can pull it out more, there you go, now thrust it back in,” the younger cooed and began kissing his cheek again. Idia gripped onto Ortho’s curvy thighs and did as he was told, perhaps with a little too much gusto. His little brother cried out, nearly getting the wind knocked out of him. “S-sorry!” he forgot he had to be gentle, Ortho was smaller after all. “No no, keep going, that feels soooo good~” Or not.
Idia continued to thrust at that pace, his panting and gasping from earlier returning. Though, he was less quiet now since he had no reason to keep his voice down. Underneath him, Ortho had begun squeaking and letting out sharp moans every time Idia rammed into his sweet spot. “God, you’re such a filthy pervert, Idia,” the younger Shroud went back to whispering devilishly into his ear. “How long have you wanted to come fuck my warm cunt while I was fast asleep?” Oh, he was becoming really weak to hearing such filthy things come out of Ortho’s mouth. “P-please…” was all Idia could muster out between moans. “Hmm? Please what? You’ve gotta use your words, Nii-chan.” Suddenly, Ortho grabbed onto Idia’s hips and stopped him mid thrust. “Answer me, or I’ll tell everyone.”
Fuck, that really shouldn’t have went straight to Idia’s cock but it did. The thought of everyone finding out how much of a sick fuck he was made his head spin. “A-a-a long time, I’ve thought of this a long time. Mmm, kept thinking about it every night before bed. Wanted to come in and… well, yeah.” Good enough, Ortho knew he could only push his shy brother to talk but so much. “Now, what is it you want, Nii-chan?” Idia bit his azure lips and looked around nervously. The younger always found that to be such an adorable habit he had. “Mmm.. can you please keep, like, humiliating me? Like… y’know telling me I’m gross and sick and stuff. If that’s not too weird.” There he went, talking at the speed of the once great Lord of the Underworld. Ortho’s big brother was just so adorable! “Weird? I’m only telling you what’s true, you disgusting excuse of an older brother. Sure, I’ll remind you more, now get back to thrusting.” A sharp slap was received on Idia’s hips and he began quickly thrusting again.
“You know, maybe I will just tell everyone anyway. How much of a slut you are for your little brother. Willing to throw it all away just for his pretty little cunt.” The mix of Ortho’s alluring voice, indecorous words, and tight clench of his pussy was driving Idia mad. This had to all be some sick dream he was having. He’d wake up the next day, boxers drenched and guilt through the roof. Yet, he didn’t want to wake up from it. He wanted to live inside of this nightmare forever.“Imagine what the headmaster will think, imagine what mom and dad will think. Idia Shroud, violating his poor, sweet, innocent brother. You don’t even care either, just using me as your own little fucktoy.” Idia’s thrusts were becoming sloppy. His balls audibly slapping against Ortho’s plush ass with each violent slam into him. “O-O-Ortho, Ortho, I can’t, I’m so close, I-I’m not-” he really was too far gone at this point. The only things his mind could focus on were the wonderful, fat cunt he was balls deep in and reaching his own climax. “Fuckkkkk, cum into me, Nii-chan. Cum into your little brother’s womb. I know you fantasize about breeding me, you perv. I saw the stuff you were searching up on your computer. Do it, blow your disgusting load into me. Mark me and let the whole world know I belong to a creep.”
That did it for him. Three sloppy thrusts later and he shoved himself fully into Ortho, his climax making him see white. Meanwhile, the younger underneath him was squealing as he was reaching his own orgasm. All their movement had caused the jacket Ortho was wearing to move around, making some of his neck exposed. Fuck it. Idia sunk his teeth in without a second thought and bit down hard. Ortho shrieked even more. The older Shroud rode out his orgasm, gently continuing to thrust into his brother until the last bit of his white ropes sputtered out. The two laid there for what felt like hours, until their breathing slowed. Idia nearly fell into slumber until he felt a pair of small hands ruffling his nest of hair. “Nii-chan, you exhausted already? I thought a perv like you would have enough energy to go multiple rounds.” The elder lifted his head up from where it was still buried against Ortho’s neck. Amber orbs stared back into his own, a warm smile coating his brother’s features.
It took a few long moments of Idia staring at him before suddenly his lip began to wobble, and a torrent of tears escaped Idia’s eyes. “Idia? Idia!” Concern flooded Ortho’s face as sobs began wracking through the older. He turned around and held his old brother close, moving his bangs to pepper kisses onto his forehead. Through his snivels and whimpers the younger Shroud could make out a few phrases Idia was trying to get out. “ ‘m sorry” and “I didn’t mean it”, as well as “I’m a horrible brother” and “Please don’t tell anyone” were what he could pick up. Ortho held Idia’s lanky face in his hands and made their eyes meet once more. “Nii-chan, listen to me. I said before that I'm not mad at you, and that I’m in love with you as well.” In love… in love? The words came as a surprise to Idia. They had always said “I love you” to each other, every day before bed and sometimes throughout the day if the occasion called. It’s what brothers did, but this? This was different, it was deeper.
“B-b-but b-but but I, but uh-” Idia tried to sputter out but was shushed by Ortho’s finger. “No overthinking, Nii-chan. I meant it, wholeheartedly. And…” now it was Ortho’s turn to get shy. It wasn’t often Idia got to see this side of his brother, with him being so full of confidence and extrovertedness. The tips of his hair burst into strawberry-tinted sparks as his cheeks flushed a similar hue. “I really enjoyed what we did here tonight, and if you’re willing, I’d love to do it again-”
“YES!”
The sudden eruption from Idia caught Ortho so off guard he sat with his mouth agape for a good few moments. “I-I-um, I mean, uh, yes. Yeah, we can, if you’re up to it," Idia mumbled in his usual tone. Ortho couldn’t help but burst out laughing. Oh, he loved his brother so much. “C’mon, Nii-chan, let’s get to bed. We can talk more about this in the morning but-” a yawn interrupted him. “I really need to get some sleep first, and you do too. You have a test tomorrow, remember?” Idia swore under his breath, that’s right he did have one. It was physical education too, even worse. “Can I sleep here tonight?” Ortho’s eyes seemed to sparkle sapphire under the light of their hair. “Of course! You haven’t cuddled me to sleep since we were little! C’mere!” Eagerly, Idia wrapped his arms around his brother again and pulled him close. He realized he never actually pulled out of Ortho this whole time. It was still so warm inside, and the younger didn't seem to mind. Whatevs, he thought and snuggled into Ortho’s nape. Tomorrow morning will surely be a lot of fun.
