Sei

“No no NO! Absolutely not!” Aoba practically screeched.

As much as he loved Sei, some things were just a bit too much. His ass getting eaten was one of them. He couldn’t understand why Sei would even want to, it was horrifying to even consider letting Sei’s tongue touch something so dirty.

“You don’t have to be scared Aoba… I just want to make you feel good…” Said softly, looking at the floor dejected.

“Can’t you make me feel good in any other way? It’s embarrassing-”

“I love you. Why is it embarrassing for me to show you that?” Sei interrupted, still pouting.

Sei could be incredibly stubborn about certain things. It’s not that he wanted to be pushy, he just genuinely couldn’t understand why some things bothered Aoba so much. In his mind there was nothing gross about Aoba, and no part of him that he wouldn’t want. Unfortunately this was a sentiment that Aoba didn’t share.

Aoba let out a long sigh, “Sei, it’s not that. It’s just… most people consider that a bit gross, so it’s scary to let someone do that to me okay? It’s not that I don’t trust you or don’t love you, it’s just uncomfortable.”

“Aobaaa” Sei whines, coming up behind Aoba and nuzzling his face into his neck.

Sei’s hands wandered under Aoba’s shirt, tracing small patterns into his hips.

“I’m not letting you…” Aoba grumbled.

Sei let out a pitiful whine as he kissed Aoba’s neck. He was never too good at accepting rejection. Part of that was Aoba’s fault of course, as he rarely told Sei no in the first place, and unfortunately this made Sei quite stubborn on the rare occasion that one of his requests was denied. Sei did seem to always get what he wanted eventually, despite Aoba’s protests.

Sei gently licked the back of Aoba’s neck, causing a shiver to run down his spine. It tickled just enough to make Aoba squirm in Sei’s hold.

His older brother always had a habit of licking, something he suspected may have been picked up from Ren as they grew closer. It was an odd feeling, but not something Aoba was entirely against, so he never stopped him. If anything, it felt quite pleasant.

“Aoba… I want you” Sei whispered, lust audible in his voice.

“Fine, just don't stick your tongue in… places… okay?” Aoba laughed nervously.

They had sex before, many times, but it still made Aoba feel a bit nervous. No matter how often they did it, he never truly got used to it. There was always a bit of guilt in the back of his mind that prevented him from ever fully enjoying it. He knew it was wrong for them to be together, but Sei just seemed so so happy… he wouldn’t dare take that from him. He was happy too of course, but he still couldn’t shake that guilt. Maybe that was why it was easier to let Sei top. For just a little bit he could close his eyes and try to forget what they really were to each other.

A sharp pain in his neck startled him out of his thoughts. Sei’s sharp canines had dug into his skin, not enough to draw blood, but certainly noticeable.

Aoba gently pushed Sei’s face away from his neck, silently telling him to stop.

“Can we?” Sei asked softly, nuzzling Aoba’s hand.

“You can touch me, just no biting please. It hurts” Aoba said gently, patting Sei’s head like one would a dog’s.

“We can have sex?”

Aoba’s cheeks grew hot and his voice cracked as he spoke, “Y-Yeah.”

He knew Sei could be a bit clueless at times, but the way he phrased things was so embarrassing. Even if Aoba knew Sei was just asking to make sure he understood properly, it still made Aoba’s face red.

At Aoba’s confirmation, Sei finally worked up the courage to initiate things, lightly pushing Aoba onto their bed.

Aoba let out a startled gasp, a bit surprised by the sudden change in position, before relaxing into the soft blankets. Sei climbed between Aoba’s legs, letting his face rest on the younger’s thigh, looking up at him with his big black eyes.

“Off please” he said, pulling at the hem of Aoba’s pants.

Aoba smiled and let out a dramatic sigh, pulling down his pants and tossing them off the bed. Leaving his boxers and shirt on for the time being.

“Can I keep these on for a bit?”

Sei nods, sitting up to remove his own clothing, opting to strip all of it off at once. Sei was never really self conscious and didn’t seem to have the same hesitation around nudity that Aoba did. In his mind there was no reason to be ashamed of his body, especially not around his own brother.

He laid back down between Aoba’s now bare thighs and softly kissed each, looking back up at the blue haired boy before kissing directly on his brother's soft dick.

Aoba let out a squeak of surprise before covering his face with his hand, embarrassed but not showing any signs of distress. As humiliated as he was, he wanted Sei to do more.

Sei continued to gently mouth at Aoba’s clothed cock until it began to harden. At which point Aoba’s thighs began to tremble.

“It’s okay… you don’t have to be nervous, ” Sei said softly, rubbing Aoba’s thigh with one of his hands, “I’ll go slow okay? There’s nothing to fear.. you can hold Bear if you want.”

Sei gestured to his stuffed bear on the bed next to Aoba, offering it to him.

Sei had had Bear as long as he could remember. Holding him always seemed to lessen his anxiety with medical procedures, so he hoped it could help Aoba’s anxiety now.

Aoba reluctantly grabbed the bear, hiding his face in its soft fur. As much as he hated to admit it, it did really help having something to hold… the strong scent of Sei on it was an added bonus as well.

“I’m going to take these off now alright?” Sei said, pulling at Aoba’s boxers.

Aoba nodded and lifted his hips up, allowing Sei to slip them off. He had to fight the urge to snap his legs shut now that he was completely exposed. Even though it wasn’t even close to the first time Sei saw him naked, it never seemed to get easier. His brother’s seemingly unblinking eyes didn’t exactly help him feel comfortable, not that he would ever tell Sei that.

“Just try to relax, I’ll take care of you” Sei purred.

The wet hot feeling of Sei’s tongue immediately overwhelmed him and Aoba had to resist the urge to buck up into his mouth. For someone who wasn’t too experienced, Sei was shockingly skilled with his mouth.

“You taste so good…” he whispered.

“Sei! You can’t just… you can’t just say things like that!”

“Why not?”

Aoba let out a strained sigh as Sei’s tongue continued to gently lap at him, making it hard to speak, “it’s just embarrassing okay… just… be quiet, please.”

Sei let out a hum of agreement that sent shivers up Aoba’s spine. Sei’s mouth felt so good, he was so gentle but it was still overwhelming and Aoba was frighteningly close already.

“Wait Sei- I’m going to-“

Sei immediately pulled back, causing Aoba to whimper pathetically.

“If you want to… yknow… be inside me, I don’t want to cum yet” Aoba whispered.

“Oh Aoba, I can’t…”

Sei looked away shyly. Aoba knew what that face meant, Sei couldn’t get it up. It happened sometimes, more often than not with Sei’s condition he couldn’t get erect. Things still felt good to him, but he couldn’t get hard, making any sort of penetration difficult. He didn’t seem to mind just taking care of Aoba though… in fact he seemed to prefer it.

“Can I just make you feel good today?” Sei asked softly, gently tilting Aoba’s face so he could look in his eyes, “Let me eat you out Aoba.”

Scrap. He knew what that was, even as the command was seeping into him he could feel it. It was his power too after all. Some part of him felt betrayed that Sei would use it in this way, but he should have known better. Sei always got what he wanted.

“I know I can’t stop you… just please be gentle. I’m scared.” He admitted.

“You have nothing to fear I promise.” Sei whispered, gently kissing Aoba’s forehead.

After a bit of hesitation Aoba flipped himself over, grabbing Sei’s bear and holding it tightly in his arms. Even with the assistance of Sei’s scrap he was still a bit terrified. Being in such a vulnerable position, even with someone he trusted as much as Sei, made his blood run cold.

He felt Sei’s gentle hands on his back first. He was so tight and scared that Sei took pity on him, opting to help him relax before he accidentally pulled something. He slowly began rubbing the tense muscles, trying to ease some of the fear. Letting his skilled hands trace Aoba’s spine, pressing into the muscles surrounding it until the tension was relieved.

After a while Aoba slowly began to relax under Sei’s soft touch. There was still a bit of lingering fear in the back of his mind, but it was now like a soft fuzzy blanket had been tossed over it. His worries seemed to be covered in a thick haze.

Without any warning Aoba felt Sei’s soft warm tongue on his entrance. He squirmed instinctively, trying to escape the confusing sensation, but Sei’s hand on his hip kept him firmly in place.

Aoba whimpered as Sei continued to gently lick at the tight muscle. He could feel Aoba’s anxiety, his body both shaking in fear and pleasure. It filled him with a sick sense of pleasure to see the effect he had on him.

“Sei!” Aoba sounded close to tears as he cried out his brother's name. He dug his nails into his brother’s stuffed bear, the humiliation of such an act starting to get to him. He didn’t want to cry, but it seemed inevitable.

The tears finally came as Sei began to push his tongue inside Aoba. Panic surged through him along with the pleasure, and it was all too much.

Sei stroked Aoba’s hip comfortingly as he began to sob. Everything was far too much, it felt incredible but the fear was beginning to overtake him. He felt disgusting, what if Sei found him disgusting after this? He couldn’t bear the thought.

“Aoba. Look at me.” Sei’s soft voice cut through his anxiety.

Aoba turned his head so he could look at Sei over his shoulder.

“Relax. It’s okay.”

It was as if a switch was turned off in his brain. His body went limp, melting into the soft blankets as Sei resumed. Now that his anxiety had been forced out of him he could finally appreciate the feeling of Sei’s mouth on him. He has to stop himself from trying to rock back into the wet heat of his brother's mouth.

“Sei- please- more” he begged.

Sei let out a soft laugh before reaching under Aoba and beginning to stroke his neglected cock.

Aoba screamed, everything he’d been feeling poured out of him all at once. The pleasure of both Sei’s tongue and hand working on him at once felt all too overwhelming, causing his body to shake violently.

He thought he heard Sei giggle through the haze of his own pleasure.

It only took him a few seconds to cum, his orgasm washed over him before he even had the chance to warn Sei. His body trembled as Sei stroked him through it. Sei’s poor bear was completely soaked with Aoba’s tears by the time it was over.

“You did so good… see I told you you’d like it” Sei purred.

Aoba felt like he’d been run over by a truck, but Sei was right. It did feel incredible. Anything Sei did to him always felt incredible truthfully, as much as his ideas scared him at first. Sei would never hurt him, and he knew that, but Aoba was a nervous person, and that wasn’t changing any time soon.

Sei moved to lay next to Aoba, opening his arms up to him. Reluctantly Aoba let himself be pulled into Sei’s embrace. He was still a bit upset that Sei had scrapped him, but listening to his brother's heart beat and feeling his soft skin against his own quieted his anger.
