Todomatsu loved watching his youngest brothers play, especially when they started roughhousing (which was quite common for them, much to Totty’s enjoyment). Osomatsu had finished off Karamatsu’s bag of chips and the two had begun fighting and wrestling over it. Todomatsu quietly took some pictures of the two boys as they pushed and pulled and rolled around the living room floor. Despite being smaller and 2 years younger, Osomatsu had managed to pin Kara and keep him pinned despite his struggling. The youngest gripped his brother’s wrists, pressing them to the floor, while he bounced on the other’s lap due to Karamatsu's bucking hips. Try as Kara might to throw Osomatsu off from on top of him, it was no use as Oso ground his own hips downwards to try and get Kara to be still.
They have to be doing this on purpose, Totty thought. How could this amazing show he was watching be purely innocent play? The way Karamatsu’s hips thrust up against Osomatsu’s round little butt, the way Osomatsu ground him back down onto the floor, the way they were getting all red and sweaty from their “playing”—they just had to be teasing Todomatsu, right? Totty will surely imagine so later, when he has time to enjoy the pictures he’s taken, which will have to be immediately deleted once he’s done "enjoying," for obvious reasons.
As Karamatsu continued to struggle against their baby brother, Todomatsu mused if he should actually wait to show Jyushimatsu the pictures before deleting them. The second-born matsu, wanting to be a responsible big brother, liked to chastise Todomatsu for looking at their youngest brothers so hungrily, but sometimes even the most innocent interactions between the two smallest had Jyushi popping a boner, so his judgment was quite easily ignored.
Todomatsu was ripped from his thoughts when he heard Karamatsu let out a loud, choked gasp. Totty's lust was immediately replaced with worry, thinking that Kara had hurt himself during his thrashing. Osomatsu stayed on top of him, though it wasn’t necessary as the older boy just laid on the floor shaking. Totty got up from his seat on the floor and approached them, “Are you okay?! Osomatsu! Did you actually hurt him?!”
Before he could get too close or too motherly, Karamatsu cried out, “I’m fine!” He continued to shake and pant as he slowly sat up, holding the smaller boy by the waist so he wouldn’t fall back during the shifting positions. “I think… I just hurt my back or something…” He turned his face to directly address the baby brother sitting in his lap, “Fine, Osomatsu, you win. Let’s go-” Karamatsu paused glancing back up at their eldest brother for a moment before continuing, “Let’s go take a nap.” From where Todomatsu stood, he couldn’t see the smallest one’s face, but he could still tell that Osomatsu’s ears were burning a bright red as he nodded and mumbled affirmatively. They slowly got up off the floor and Todomatsu immediately noticed the way one of Kara’s hands pulled down on the edge of his shirt, covering his crotch. Osomatsu held Karamatsu's free hand and intertwined their fingers as they walked out of the room.
It wasn’t uncommon for the two to take naps together. They liked getting all tangled up under a blanket on the green couch in their bedroom for nap time, but Todomatsu had a suspicion that they weren’t going to be napping at all this time~ He waited a while before following suit and heading towards the bedroom to catch a peek. With the door opened just a crack, he saw the boys readying for their nap. They shuffled under the blanket and quietly mumbled to each other to shift this way or that or to wait a moment. Eventually, they settled, Karamatsu laying down on his back and Osomatsu laying on top of him, resting his head on his big brother’s chest.
For a few moments, they stayed still, simply cuddling on the couch. Todomatsu huffed and felt a little stupid. Karamatsu was probably just fidgeting with the hem of his shirt before, of course his little brothers weren’t about to fool around. They were probably still too young for that stuff anyway (not that Totty was a good judge of that kind of thing, having grown up sneaking onto naughty sites at an early age himself). Just as he was about to bail and go look through his pictures in the bathroom, he saw the blanket begin to move. It swayed slowly back and forth as the silent room began to fill with small gasps and little grunts. Osomatsu had his face completely buried in Karamatsu’s chest, his hands tightly clinging to the fabric on the other’s shoulders. Since Karamatsu had nothing to hide behind, Todomatsu could clearly see his little brother’s small red face. His eyes were shut as he quietly panted and occasionally groaned.
Every drop of Todomatsu's attention was drawn to his younger brothers humping under their shared blanket, most likely grinding against each other through their pants. When had he gotten his phone out to record? Totty couldn’t even recall, he was on autopilot as he watched the blanket’s swaying speed up and heard their volume rise. However, he still managed to keep his autopilot mode from making Todomatsu stroke himself. The last thing he wanted was to explain to anyone who might come home without him noticing why he had his hand down his pants in the middle of the hall. It’d be harder for Totty to control himself if he started rubbing one out anyway, so he forced himself to be content with just watching and recording.
That was all thrown out the window once he heard his darling baby brother sweetly, pathetically whine out “Nii-chaaaaan~!” How could Todomatsu possibly hold himself back after that?! He could feel that whine go straight to his dick, making it twitch and grow faster than before. He let out a breathless chuckle and turned his phone’s camera onto himself. Todomatsu smiled right into the lens, knowing for sure that he was going to show this to Jyushimatsu.
The eldest slid the door open very slowly and feigned being focused on his phone to give the younger two the opportunity to scramble and attempt to make it appear as if nothing was happening. He then moved towards the bookcase as he heard the little ones shuffle about under their blanket and pretended to look for a book to read. In reality, he was just looking for a good spot to set up his phone. Todomatsu did end up grabbing a book before stepping away from the bookcase—something big that would give the impression that he was going to be reading for a while—and went to sit on the part of the couch that the other two weren’t taking up, by their feet. Todomatsu pretended to slowly read through the pages, though he honestly couldn’t care less about teaching himself how to code (he went online to look cute, not be a nerd). His real attention was on the blanket lump he could see out of the corner of his eye.
Karamatsu had his face screwed up, doing a terrible job at acting like he’s asleep. Meanwhile, Osomatsu had the benefit of hiding against Kara’s chest, though he was clearly still twitching and breathing hard. Totty tried really hard not to laugh when he caught the blanket begin to sway only for it to abruptly stop with a whine from the youngest. No doubt, Osomatsu was becoming impatient and the older boy somehow got him to settle down. This repeated few more times, the youngest getting whinier each time.
The next time he started up, Todomatsu placed his hand on Osomatsu’s back, making him jump and then finally freeze in place. Totty began to rub and sweetly asked, “You okay there?” There wasn’t a response as he continued to rub Osomatsu’s back and then chanced a glance at Karamatsu. Their eyes met for a split second before the younger one screwed his face back up to resume his terrible portrayal of a sleeping person. Poor thing was clearly pissing himself in fear (hopefully just metaphorically, Totty was not cleaning that up) that they were going to get into big trouble.
“OW!” Osomatsu cried out, quickly sitting up and completely blocking Karamatsu from sight with the blanket. He whipped his head around to look at his eldest brother and tattle, “Karamatsu-niisan pinched me!!”
“Just stay still!” Karamatsu loudly ordered.
“Shut up! Don’t tell me what to do! I don’t wanna stay still anymore!!” The youngest punctuated his response with a big bounce on Karamatsu’s lap, earning loud moans from both of them. This was then followed by another cry from Osomatsu, “Ow!” They struggled for a moment before Oso was able to pin Kara’s wrists to the couch cushion. He then resumed his previous movement and began to moan shamelessly, present company be damned.
Todomatsu stared on, slightly shocked that Osomatsu really just… went for it. Right in front of him. Totty didn’t even need to play any mind games or trick them into showing him what they were doing. Is the youngest of them seriously also the horniest? Todomatsu nearly felt invisible as he watched the blanket slowly fall to the side due to Oso’s erratic movements (though, Totty may have helped it fall a tiny bit faster), but the eldest could finally get a good look at what the other two had been up to. To his amazement, Karamatsu’s dick was actually going in and out of their little brother’s ass. He really thought that they couldn't have been doing more than just grinding on each other… How long had they been doing these kinds of things?! Did they do this every time they took one of their “naps”?! How much of the good stuff had Todomatsu missed out on?!
The eldest spared a look over towards his phone on the bookshelf, nearly having forgotten it. He gestured towards the horny little animals going at it right next to him and made a face that he hoped would convey the feeling of “Are you fucking seeing this? Look at this!” Jyushimatsu didn’t even need to see the pictures taken earlier, this recording was literally that, but a thousand times better. Todomatsu refocused on the lovely scene before him to really soak it in and record it to memory as he started to rub himself through his pants.
Like earlier that day, Osomatsu was bouncing on Karamatsu’s lap while pinning the older one’s wrists down, but now he was also awkwardly riding the other’s cock. Osomatsu’s lack of experience was evident by the way he jerked his hips and Todomatsu looked over at the phone camera once more. He merely gave a shrug, knowing that Jyushimatsu would never let him live down what was about to happen next. As it turned out, Todomatsu really didn't care about being a "good big brother," at least not the way Jyushimatsu did.
Totty laid his hands on Osomatsu’s small hips, stilling him immediately. Oso really did seem to have forgotten that he and his brother had an audience. Todomatsu spoke sweetly as he leaned in against the little one’s back, “Here, try doing it like this.” He then began to move Osomatsu’s hips for him, moving them in a circle. The awkward jerking from before was now a smooth gyration, earning new, louder moans from both of the young boys. Todomatsu desperately wished he could pull out his own dick and shove it into one of the other two, but that would definitely ruin his chances for more fun in the future. This day was already so much of a blessing, Totty told himself to be grateful for just cumming in his pants from watching this show and being able to have the smallest matsu’s hips in his hands. As Osomatsu continued to let himself be guided, Todomatsu cooed in his ear, “That’s it, gooood boy~ Good baby boy~” The youngest mewled as his hips sped up and he laid himself back down on top of Karamatsu and clung to him. Todomatsu couldn't help going back to rubbing himself off at the sight.
Now that Oso was laying down once again, Totty was able to get a look at Kara. The poor boy’s face looked like it was painfully red, his thick eyebrows were knit together tightly, drool ran down the side of his mouth as he groaned, and big tears were rolling down his face. When he pried his eyes open, he risked a look towards his big brother, clearly still fearful. Despite obviously enjoying himself, Karamatsu was probably still scared of getting in trouble after this. Todomatsu smiled and sighed. The hand that wasn’t busy groping his own dick reached up to pet his brother’s head and reassure him, “You’re a good boy too~”
Karamatsu’s face shifted from surprise to back to being screwed shut as he wrapped his arms around Osomatsu’s waist and began thrusting upwards more rapidly. In turn, the youngest let out his loudest moans yet, crying out, “K-Kara-niisan! -ra, ahh~! Nii-chan, more! More, nii-nii! Please, nii-nii!”
Todomatsu felt himself ruin the front of his pants against his hand as his eyes were glued to the scene of Karamatsu digging his nails into their baby brother’s hips and ramming up into that sweet little ass, which Totty swears to himself he will one day also ram into. Karamatsu’s hips soon stuttered and then stilled while they both moaned loudly. The two youngest brothers clung to each other as they came together and then fell back down onto the couch, finally relaxing.
All three of them panted, coming down from the highs of their orgasms. Todomatsu watched the other two hug and nod off. It looked like they were finally ready for that nap. The eldest looked over at his phone again, and gave the future Jyushimatsu that would be watching this one more smile.
