The matsuno household was always quiet during the evenings. Osomatsu hanging out at the pachinko, Choromatsu at one of Nya-chan's concerts, Jyushimatsu playing baseball and Totty hanging out with his girlfriends.
It seemed like the only time that Karamatsu could truly enjoy himself, and more precisely his body.
After making sure that Ichimatsu is taking his usual nap, Karamatsu's sweaty, shakey hands grabbed his favorite mirror and his trembling, excited legs carried him into the living room where he could finally be alone, and mostly importantly, free.
It was no secret that Karamatsu loved admiring his features reflected on the mirror, his perfect thick brows and long dark eyelashes that adorned a pair of chocolate eyes, his small button nose and full rosy lips that he couldn't help but sink his teeth into.
Karamatsu had a secret though, one that the others couldn't find out about...He only has the best orgasms when staring at himself, at his face changing from normal to flushed, his forehead decorated with droplets of sweat and his eyes glazed over and teary,his cheeks cherry red and his lips wet and bruised from the biting and licking, his voice rising higher as moans and needy whines slip out between throaty pants, trembling lips forming O's as he nears the edge of euphoria.
All while the mirror is in his hand, the other teasing his tip and gathering the precum to use it as lube against his twitching hole.
One thing Karamatsu loved to do was fantasize about each of his brothers, testing their names by whispering and moaning each one softly until he found the one that drove him over the edge, and somehow, it always ends up being just one of them....
"I-ichimats-su..Aah~", his hands started automatically moving slower and tighter, almost painfully blinding but pleasing as he imagined the sadistic look on Ichimatsu's face while he teases him and degrades him,
"Ah, ah aren't you just a perfect little slut, karamatsu? You love it when I tease you like this, eh~ ?"
Karamatsu could almost hear Ichimatsu whispering those humiliating words in his ears, could almost feel his younger brother biting his rosy nipples and squeezing his thighs, could almost see his grin full on display and those devilish eyes staring down at him.
"P-please, please, please Ichi- I can't...hnngh..fuck I-I want to-I need to..", Karamatsu's whimpers and needy whines continued growing louder and louder, fully lost to ecstasy.
Until his mind suddenly generated an image of Ichimatsu's teasing dark eyes, smirking lips and rough hands choking him, wrapped around Karamatsu's neck while whispering in an encouraging, almost humiliating tone telling the older brother to "Go on, slut..show me how much you want my cock inside you, Cum for me."
That's all it took before Karamatsu's hand let the mirror fall on the table, curling around his mouth to stop his silent scream from being heard all over the housewhile his hard, edged cock started spilling cum all over his body, creating a pool of cum under him and across his soft belly.
Dark spots danced across his vision as he kept going and going, cumming more to please his imaginary dominating Ichimatsu until he couldn't anymore.
He laid down on the floor, exhausted and throughly fucking pleased, a giggle escaping his mouth because holy fuck that was one of the best orgasms he ever had.
He took a few minutes to regain his senses before cleaning up his mess, an even darker blush spreading across his cheeks as he wiped the cum from his body, shyly tasting it a bit and moaning around his finger.
Little did Karamatsu know, on the other side of the door, Ichimatsu was clutching his pants, the front of it wet with the cum his cock spilled after jerking off to his older brother's needy moans,especially the ones moaning his name so loudly that it had woken him up from his light nap.
