Glitch

Katsuki’s pulled from a nightmare by a strong tug on his sleep shirt.    He catapults into wakefulness with a shuddering breath and sits up. After rubbing the tears out of his eyes furiously, he glances down at what woke him.    “You were screaming again, big bro,” Eijiro, his younger brother, says softly, thick eyebrows furrowed adorably. His chubby cheeks puff out and his dark hair looks like a tumbleweed.    “Sorry about that lil man,” Katsuki says, voice scratchy.    Eijiro’s cheeks puff out further. “Kat, I’m twelve years old; it’s a little insulting.”   Katsuki breathes out a laugh. His brother’s indignant tone matched with the fierce look in his red eyes (so like his own) somehow proves Eijiro’s point; that he’s not quite a child anymore. Even still… “You’re my little brother; you’ll always be my lil man!”   Katsuki scoops up Eijiro from the side of his bed, groaning with the unexpected heaviness of his brother. Eijiro fights back feebly and Katsuki easily maneuvers them until they’re both under the covers. Eijiro snuggles into his hold, his back to Katsuki’s front. He easily takes Katsuki’s arms and positions them how he wants them around his waist and starts drawing shapes idly on Katsuki’s arms.    It’s soothing. The vestiges of the Katsuki’s nightmare drift away and the warm, smooth touch of Eijiro replaces it. Just as he’s about to drift off, Eijiro shifts them again until they’re face to face. Well, chest to face. Eijiro’s shorter than him (much to Eijiro’s annoyance); when Eijiro snuggles into him, his face comes up to his chest. One of his skinny legs nestled itself between Katsuki’s legs.    Eijiro has always been the more affectionate and tactile of the two of them. Usually Katsuki pushes him away for the sake of his devil may care attitude, but tonight he lets himself lean into the affectionate touches. Eijiro’s arms encircle him, rubbing his back slowly. He’s always been able to calm Katsuki down, even better than their parents. Now is no exception, Katsuki slipping into sleep once more in this new position.    Until Eijiro shifts again, his thigh sliding against the underside of Katsuki’s dick. The touch jolts him awake and he looks down at Eijiro. His younger brother is sound asleep. Katsuki sighs slowly and forces himself back into a relaxed state. He’s just moving in his sleep!     The next time that Katsuki wakes, it can’t be more than an hour or two later. For a moment, he doesn’t know what’s woken him, only that he feels too hot. He goes to rub at his eyes but finds that his arms are tamped down to his sides by a surprisingly strong grip. He shivers suddenly and looks down, watching almost as if in slow motion, as Eijiro’s open mouth breathes directly against his nipple. Katsuki realizes that 1) he’s woken up because of Eijiro’s… attentions and 2) he’s rock hard, his dick digging into the softness of Eijiro’s belly.    Eijiro seems to stir for a moment, sensing Katsuki’s suddenly rigid body, but he falls back into slumber easily, his lips mouthing over one of Katsuki’s nipples. Katsuki realizes that his arousal is what woke him, and that it’s past the point of being tampered with a cold shower. With grim resolve, he carefully removes himself from Eijiro’s hold and lies on his back. He quietly pushes down his boxers until his erection is completely free. He hisses at the feeling of his scratchy sheets against bare, heated skin. He feels like an exposed nerve subjected to 1000 watts of electricity.    Just as he’s reaching for his aching dick, the sound of sheets and a yawn make him pause. He slowly turns his head and watches in real time as Eijiro wakes, recognizes where he is, and lays his eyes on Katsuki. His large eyes widen as he takes in Katsuki’s half naked form.   “Big bro…?” Eijiro sounds breathless, his ruby red eyes stuck on Katsuki’s dick that jerks under the attention.    “Fuck, Eiji, go back to your room,” Katsuki growls, wanting to desperately touch himself, even if it means doing so in front of his younger brother.    Eijiro’s face goes from bewildered amazement to determination, and a sharp tooth peeks through his thick lips as he bites his bottom lip. “No.”   Katsuki gasps in shock, arousal dripping into his lower belly at how sure and… authoritative Eijiro sounds. “The fuck you mean ‘no’? Do what the fuck I say!”   Eijiro’s eyes finally meet Katsuki’s annoyed gaze. There’s a heat there that Katsuki’s never seen in his eyes. A shiver scatters down his spine and his erection twitches in his boxers. He’s old enough to recognize he’s aroused, but he can’t comprehend why he’s aroused now of all times. Well, that’s not true; there’s a small voice in the back of his head shouting at him the why’s and the how’s. He squashes that voice mentally with his foot.   “Eijiro, go back to your fucking room. Or we won’t go to the beach tomorrow.” Katsuki smirks, knowing that the threat will get Eijiro to comply.    “Then I guess we’re not going to the beach,” Eijiro says with a shrug of his thin shoulders. He reaches forward and his hand grazes against Katsuki’s dick.    Katsuki bats his hand away, feeling a blush rush to his cheeks and the back of his neck. The touch is slight but sure, and he holds back a groan and asking for more. “Seriously, Eijiro; get the fuck out of my room!”   Katsuki’s tone is sharp as a whip and he notes without any real satisfaction that Eijiro flinches. His fat bottom lip trembles slightly and Katsuki sighs in resignation. “Fine, fine, buddy; you can stay. But just… Let me go to the bathroom–”   The rest of Katsuki’s sentence is swallowed up by Eijiro’s eager and clumsy mouth over his own. It’s simply a mashing of lips together, but Katsuki feels it all the way to his fucking toes. He gasps in shock and Eijiro’s small tongue invades his mouth easily. There’s no finesse like he sees in movies or the occasional porn flick, but the passion and want from the kiss is enough to make Katsuki start leaking precum. Without breaking the kiss, Eijiro manages to push Katsuki onto his back. He straddles Katsuki’s narrow waist and ruts against him. He gasps into their kiss because he feels something slightly bigger than his own erection rubbing against him.    A fire ignites inside Katsuki and suddenly he’s kissing Eijiro back. He’s no expert either, but he’s at least french kissed someone before. Like the big brother he is, he takes over the kiss and guides Eijiro’s lips and tongue until the kiss melts his bones. Eijiro thrusts down, his sizable dick rubbing against Katsuki’s. The friction from their clothes and their hardness rubbing together makes Katsuki shudder.    Suddenly, Eijiro pulls away from their heated kiss. His pupils are blown and there’s spit glistening on his lips. He doesn’t give Katsuki time to think, diving for the juncture of where his neck meets his shoulder. Eijiro bites down as he humps hard against Katsuki. Katsuki shudders from the dual sensations and grabs Eijiro’s hips. Eijiro laps at the bite marks he’s left and his coarse tongue has Katsuki gripping his hips even harder. When Eijiro shifts on top of him, Katsuki moves Eijiro’s hips back and forth forcefully.   They both moan at the force of their humping. Eijiro finds Katsuki’s mouth again and the intensity of it goes straight to Katsuki’s dick. His balls feel incredibly tight as Eijiro pulls at his bottom lip with his teeth. This time when they break apart, Eijiro’s smirking.   “Gonna cum?” He pants, pushing Katsuki’s shirt up until his pebbled nipples are exposed. He grips at Katsuki’s pecs and takes over the rhythm of their movements. He shifts his hips down so that when he trusts upward, his dick rubs against Katsuki’s asshole and the underside of his balls.    “F-F-F uck , how do you even–”   “I spy on you sometimes,” Eijiro admits, looking away briefly. “When you’re um, masturbating.”   Later, Katsuki will yell at Eijiro. But right now, that revelation tips him over the edge and he paints the inside of his boxers with his cum. Eijiro keeps thrusting through his sensitivity, chasing his own orgasm and Katsuki is helpless from bliss to stop him.    Eijiro cums a few moments later, cum spilling onto Katsuki’s exposed lower stomach. When did he take his dick out?     Katsuki is the first to recover from post-orgasmal bliss. He all but throws Eijiro off him. With a thump, Eijiro falls to the ground, letting out a strangled sound. Katsuki’s still too blissed out to properly feel the rage he knows simmers beneath the surface. Even so, he’s able to snarl out, “Get the fuck out of here before I beat your fucking ass.”   Eijiro whimpers, all traces of the sexual deviant from before gone, and in its place is the frightened face of a middle schooler. It’s almost enough to make Katsuki feel sorry for him. Almost. When the silence stretches with no sign of Eijiro leaving, Katsuki growls. That seems to snap Eijiro out of it and he scrambles to get him, his shorts still hanging just below his now flaccid dick. If the circumstances were different, Katsuki would find it hilarious.  Once Eijiro’s gone, he lies on his back, staring at the ceiling as if it it’ll hold all the answers as to why and what the fuck just happened. Maybe it could also tell him why he wants it to happen again.
