It was a warm autumn day, the Shinsengumi quarters quiet save for the distant sounds of swords clashing at the training grounds. Normally, Ryoma would be out with his troops doing missions, but he sent them all off on their own today, due to a hangover from drinking the night prior. Instead, he sat in the shade of the ancient tree to avoid the rays of sunlight and polished his sword. His mind wandered, thinking about what meal he should make later to have with Haruka.
A door slid open, snapping him from his thoughts, and he glanced up. The room next to his - Nagakura’s, if he remembered correctly - had been propped open. Ryoma was slightly suspicious, as no one stepped in or out, but he hoped it was just the man wanting to enjoy the cool breeze whistling through the leaves. He dismissed it for now, returning to his task.
It took him only a minute or two to realize that this was not the case.
It was the low moan that brought his attention back to that room, trying to decipher the sight before him. Nagakura’s upper half was mostly shadowed by the way the light was angled, his shirt raked open and exposing his bare chest. Kneeling at his feet was Okita, his right side facing the outside - his eye meeting Ryoma’s as he takes Nagakura’s cock back into his mouth.
Ryoma was stunned, unable to look away from that eye which crinkled gleefully at the attention, watching Okita hollow his cheeks and suck off the second division captain with vigor. Nagakura’s hand settled into his hair, his hips rocking as Okita bobbed his head. Ryoma felt the blossom of heat on his cheeks as he finally processed what he was seeing, quickly glancing away and placing his sword at his side to cover his face.
His heart raced; it was too late for him to walk away and pretend he hadn’t seen anything, the image of Nagakura’s cock speared into Okita’s mouth burned into his mind’s eye. And Okita knew that he’d seen, he remembered the smile in that mischievous eye of his. Not to mention the fact they were doing that in front of the door… does that mean…
A choked noise had him on alert again, his first thought was someone choking on blood – but no, he’d somehow forgotten within one second that there was someone deepthroating dick only a few yards away. Now, Nagakura had a hold of that little ponytail, using it like a lever to force Okita’s mouth on his cock, drool and precum dribbling down his chin. Ryoma took in the sight of that fucked out face, his watering eyes and reddened lips, and felt the growing interest in his hakama.
They were doing this on purpose. They wanted Ryoma to see - not just Okita, but both of them; his eyes were now adjusted and he could see Nagakura wasn’t looking down, but at him, a cocky smirk alighting his face when he was caught. The blush Ryoma had started making its way to his chest and ears, his whole body aflame, having been caught staring not just once, but twice now. He wasn’t even sure what to do now besides watch as the first division captain slurped heavily, massaging the other man’s sack.
“Soji…” Nagakura’s labored breathing signaled he was close, his attention refocused on Okita. With a stutter of his hips, he gripped his head, keeping that mouth on him, moaning low as he came.
When he saw Okita pulling back, dreamy expression to his face as fluids leaked from his mouth, showing off Nagakura’s load to him, Ryoma stood straight up like a bolt of lightning hit him.
Scooping up his sword, he stared at the door to his room and made a beeline straight for it, opening and sliding it closed behind him with a snap. He clumsily sheathed his sword and then clumsily unsheathed his other sword, his dick red and weeping in his hand. His arousal was all he could think about, unable to think as he searched his belongings for his jar of clove oil.
It was embarrassing how quickly he came, having only thrusted into his hand twice before spilling onto the floor. And he felt that embarrassment sweep over him as he heard light laughter from next door, quickly taking care of his mess and burying himself on his futon.
