Chapter Text
By the time Shinichiro returned to their apartment with takeout food, Mikey was already fast asleep on the couch. He put their dinner in the fridge for later and carried the younger boy to their room.
Mikey was almost nineteen now and heavier than ever, but Shinichiro was used to it and could carry him with ease. It had just been the two of them for over a decade and though he had aged physically, mentally Mikey was still just a kid, even moreso since losing Draken a few years ago.
Shinichiro tucked him into bed, but Mikey stirred, half-awake. “Gege…” he mumbled, eyes still closed, his fingers blindly searching for Shinichiro. He took Mikey’s hand in his and bent forward to kiss his forehead.
But the younger Sano had been lying in wait, a young lion trying to lure in his prey. As Shinichiro pressed his lips to Mikey’s temple, the younger Sano wrapped his arm’s around Shini’s neck and pulled him into a real kiss. As soon as the initial shock from the surprise-attack faded, Shinichiro melted into the embrace, his lips parting against Mikey’s.
Mikey reached for the growing bulge in Shinichiro’s pants and started to tease him, coaxing out soft moans and whimpers. Shinichiro’s lips moved along his jaw and down to his neck. He lifted his head slid his fingers between the waistband of Mikey’s pants, keeping a close eye on Mikey’s face, reading his features any hint of hesitancy. When there was none, he slipped one, then two inside of him. Mikey clenched around his hand as Shini began to gently thrust, making circles on the tip of his testosterone-enlarged clit with his thumb.
With his free hand, Shinichiro lifted Mikey’s shirt to reveal his bare chest. He kissed along the faded surgery scars before moving on to nipple, flicking one with his tongue while Mikey played with the other himself.
Mikey’s little cries of pleasure was starting to make the throbbing in Shinichiro’s pants unbearable. He pulled out his fingers, licking the wetness off of them. “I was close,” Mikey mumbled, making a pouty face.
Shinichiro placed a kiss on his nose as he took off his belt. He pulled down both of their pants and spread Mikey’s legs, taking a moment to appreciate the sight before him. Mikey kept wriggling, though, making desperate little whines. “I’m getting to it, you big baby,” Shini teased, kissing one of Mikey’s legs as he placed them over his shoulders.
He rubbed his tip against Mikey’s clit, and then his opening. His little brother tried pulling him down with his legs. “Shiniiii…” he cried, “Please.”
Shinichiro thrust into him, penetrating as deep as he could go in that position. Mikey’s breath hitched in his throat, and he reached for Shinichiro, knotting his fingers in his hair.
Shini started slow, but Mikey begged incessantly for more, harder, deeper. Shinichiro obliged, sweat dripping down his face and shoulders as he fucked his little brother harder, deeper.
”Oh fuck,” Shini breathed, Mikey’s pussy conracting almost rhythmically around his cock. Using one hand to keep himself from crushing the smaller Sano, Shini used the other to play with his clit again. Mikey twitched and his back arched against Shinichiro as ecstasy took over him. His older brother slowed, then paused, Mikey panting heavily. Shinichiro kissed him gently, then kissed his cheeks and nose.
“Do you want me to stop?” he asked. Mikey’s face was flushed, and sweat coated both their skin.
”No,” Mikey replied breathlessly, shaking his head. He pulled Shinichiro into another short but tender kiss. “I’m not done until you cum inside of me,” he whispered against Shini’s lips.
“Then may I…?”
Mikey nodded, a smile playing at his lips. Shinichiro pulled out slowly, then placed two fingers against Mikey’s lips. “Lick,” he said. It was a command, but gentle, the kind that made Mikey melt in his hands. His little brother’s lips parted.
Then, Shinichiro flipped Mikey onto his stomach, rubbing the rim of his hole with his now-wet fingers. He pushed two inside, fingering him slowly. Mikey was especially tight here, so Shinichiro was always sure to take extra care in warming him up.
“More,” Mikey panted, clutching one of the pillows by his head so hard that his knuckles were turning white.
“I don’t want to hurt you,” Shinichiro told him.
”I don’t care.” Mikey raised his hips, pushing back against Shinichiro, and began fucking his fingers.
Shini couldn’t hold back anymore. Mikey’s moans were driving him wild. He pulled his hand away, grabbed his brother’s waist and shoved his way inside of him. Mikey cried out, tightening around his cock, whimpering as Shini began to thrust. He didn’t start gentle this time, and it took a few moments for Mikey to get used to him, his pained whimpers replaced by those of pleasure. Shini could see the tears in his brother’s eyes while it was hurting him, but he never asked him to stop. The little masochist never did.
When Mikey came a second time, Shinichiro fucked him through his orgasm, not stopping this time around. He could feel his own climax building, especially with the way Mikey’s hole was starting to constrict, but he didn’t want to end it like that. He paused to take off the condom before burying himself in Mikey’s ass again.
Mikey felt the warmth spread inside of him as Shinichiro filled him with his cum. His big brother rubbed circles against his lower back while his dick throbbed inside of him still. “Good boy,” Shinichiro murmured. If he weren’t already fucked out, Mikey probably would have climaxed a third time at the praise.
Shini got a warm, damp towel to help Mikey clean himself off. Then he crawled into bed beside him, arms wrapped around Mikey’s narrow waist. His little brother kissed his cheek and nestled into him before they both fell asleep.
