Summary: Sai uses Reishin's sins against Kouyuu.
As the boy’s mouth closes around Sai’s cock, he leans back in his chair and hums. It’s such a pretty mouth, Sai thinks, at least its pretty when Kouyuu is not spoiling the effect of those pale pink lips by speaking out of turn. It’s something the boy manages to do even when polite formalities seem to officially fall from those lips, but there is always something lingering there beneath them that speaks of contempt - that speaks of Reishin. Reishin does not bother to curve his distaste, yet Kouyuu can somehow thread it into something as simple as the ‘respectful’ tilt of his head …
It is, at least, what Sai sees. He is not quite so foolish that he doesn’t realise that he projects his disdain for Reishin onto his adopted son, but such things hardly matter when it means that he can … project … other things onto Kouyuu as well. With a smirk, he laces his fingers deep into Kouyuu’s hair and draws him in closer, delighting in the way Kouyuu chokes quietly as Sai’s cock buries itself deeper in his throat. This is how it is supposed to be, with the retched Kou family on their knees and doing exactly as Sai pleases. He doesn’t release his grip on Kouyuu’s hair as he fantasizes that the boy is first Reishin and then that useless Shouka, before allowing his eyes to drift back open and fixate on Kouyuu once again. Kouyuu is certainly attractive enough in his own right, although Sai thinks that the boy would certainly have far more marriage proposals if others ever saw him like this; partly veiled by Sai’s robes as he kneels submissively at Sai’s feet. He is tempted - very tempted - to command Kouyuu to take his daughter while Sai watches on in a ‘supervisory’ role, as the only thing that would bring him more glee than destroying the Kou clan would be joining it. He certainly approves of Kouyuu as a prospective son-in-law.
However, he can be just as vain and as selfish as that bastard Reishin, and while he may allow his daughter access to Kouyuu later, right now Sai has no intentions of sharing. It brings to mind the sudden thought that it is perhaps this which binds Reishin so strangely to the boy - it certainly isn’t anything remotely similar to affection or love - and it is with the image of Reishin bending Kouyuu over his desk that Sai comes. On reflex, his hand slips around the back of Kouyuu’s head and holds him in place even as the boy tries to draw back. He keeps Kouyuu there even when he has spilt all his seed into Kouyuu’s mouth, savoring the feel of the boy between his legs. The moment he does release him Kouyuu stumbles instantly to his feet, his strangely pale hair shielding away eyes that may or may not gleam with unshed tears. They had the first time they did this, as well as the second and the third, but Sai doesn’t bother to check to see if he has managed to draw such a response from Kouyuu once more. He is too busy rearranging his robes, too busy chuckling to himself as Kouyuu flushes darkly (no amount of hair can hide that away) when a servant enters and knows. It is almost a pity that Sai has such good staff, as Sai can just imagine the admiration that he would get from all of the others if they knew he was bedding the ‘untouchable’ Li Kouyuu.
Not that Sai would be alive very long to enjoy it. Still. A man was allowed to fantasize about such things.
“You are free to leave,” he waves dismissively, and Kouyuu does not need to be told twice. “I am sure Reishin is impatiently waiting his turn.” Kouyuu loses his step momentarily at Sai’s deliberately casual words, before closing the door behind him with a touch more force than necessary.
This time, Sai knows that the disdain is all Kouyuu’s own if only because Reishin’s is never tainted with humiliation and disgust.
***
Shuuei knows something is wrong. Kouyuu rarely smiles without prompting, but even Shuuei can no longer draw one from his best friend. He's plotting the best way to get Kouyuu drunk when a rebellion breaks out back home, and he has no choice but to return to the Ran province.

It’s just sex, Kouyuu tells himself as he is thrust against the wall, the smooth wood against his cheek in stark contrast to the rough hands that shove his robes up around his waist and grab at his hips. That he barely knew what sex even was just a few weeks ago isn’t important, because he knows now that Shuuei is right in seeing it as little more than a transaction.
Which makes me the whore, Kouyuu thinks wildly, and he has to bite back the beginnings of a hysterical laugh as Sai leans eagerly against him, his heavy weight pressing Kouyuu further against the wall. The other man is like an animal in heat, and Kouyuu can practically taste Sai’s raw lust as he breathes heavily against Kouyuu as he fumbles with his own robes. Kouyuu had known, he’d known the moment that Reishin had so blithely commented about just how interesting Sai looked in his strangely dyed roles in front of everyone that they would end up here, end up like this.
“Thinks he knows everything, that bastard,” Sai murmurs breathlessly against the back of Kouyuu’s neck, before there is a strange ripping sound that makes no sense until it makes far too much. His eyes widening just a touch in fear, there is little Kouyuu can do as Sai fumblingly stuffs the piece of silk into his mouth.
Then, there are no more clothes separating the grotesque man from him, just hands and lips and rambles about Reishin -
Kouyuu screams as Sai thrusts into him, and even the makeshift gag can not stop some of the sound seeping into the empty corridor. Sai doesn’t care, he doesn’t care, and Kouyuu knows it’s not really him that the other man is fucking and yet it doesn’t change the fact that it’s Kouyuu who is there.

Reishin’s gaze narrows when the servant informs him that Kouyuu has taken ill and won’t be coming into work with him. He doesn’t go check on his son because that would surely create the wrong impression, and he is hardly all that surprised, anyway. Kouyuu has been looking run down for weeks, it is about time that his son’s common sense caught up with his obsessive work ethic. That it takes his son three days to recover and that there is still something strangely fragile about him even after that does cause him some concern, but then Shuurei finally returns from her latest trip and Reishin forgets all about his son for several weeks.
***
Sai seeks out the boy whenever and wherever he pleases. Others are used to Kouyuu going missing for long periods of time and turning up in the most oddest of places, and so if people suspect that Kouyuu has been secretly on his knees in front of Sai in the archives or been fucked hard against any available wall, then they've surely been suspecting it for years longer than is warranted. It helps that Kouyuu is always one of the first to arrive and the last to leave, and as Sai becomes more daring in the uses he finds for the pretty, ridiculous boy, he turns this to his advantage.
"No." Kouyuu's firm denial causes Sai to harden further, something that does not escape Kouyuu's weary notice. "No. Not here. If you give me a moment to lock up-"
Hm. Interesting. He has never hit Kouyuu before. In fact, Sai doesn't think he has ever hit another person in his life. Yet, seeing Kouyuu crumbled at his feet, a mixture of pure rage and horror reflected in eyes that have started to glaze over in recent weeks with emotionless disinterest, is so intoxicating that Sai wishes Kouyuu would stand up simply so he could knock him to the ground once again.
"I think you forget just how damning the letters I have are," he says coldly when Kouyuu remains on the floor. "Reishin would be executed before the day was out of they were to become public." Kouyuu does not need reminding, and Sai watches in glee as his pale hands clench helplessly into fists. So, so pretty, and yet so unflinchingly stupid. Sai plans to make the letters public the moment he bores of Kouyuu and his delicious, unfailing obedience. "Now, get up and bend over the desk."
It's Reishin's desk, and it's Reishin's office, and it's Reishin's son's face that Sai forces down into the oak wood, his fingers knotted in Kouyuu's strangely pale green hair as he leans in against the back of they boy's legs. Even the soft, masculine scent that Reishin wears still lingers in the air, and Sai finds himself becoming drunk on it.
"Good boy," Sai purrs into Kouyuu's ear as his hands crawl up along the outside of Kouyuu's legs. "Good, good boy." His thumbs mockingly massage the inside of Kouyuu's thighs as he slowly pushing the heavy folds of his robes out of the way. Kouyuu is trembling. Sai thinks he's at his most beautiful when he does. "You've done this before, haven't you?" His biting tone causes Kouyuu to flinch, his lavender eyes squeezing shut as though by closing them this will suddenly all be over. The thought of being taken here of all places repulses Kouyuu as much as it makes Sai impossibly hard. He takes Kouyuu hard and fast then, living, breathing, being Reishin in a way he imagines that even Reishin himself doesn't dare be, and it's all too much that Sai comes with ridiculous quickness. It leaves him feeling irritably unsated as he pulls out of Kouyuu, at least until his eyes fall just to the left of Kouyuu's head. Kouyuu's gaze follows.
Reishin has left one of his precious fans behind on his desk.
Sai smirks.
Kouyuu blanches.

Ryuuki knows that Kouyuu is sleeping with someone, although he isn't entirely sure who. He's certainly curious about who it might be, although in the end he doesn't pry. After all, if anyone knows the benefits of anonymous sex, it's Ryuuki.
