❋ You bump into Sanzu, Ran and Rindou as they’re leaving the interrogation room. You’re deep in conversation with the resident nurse, but you don’t miss the frown twisting up Sanzu’s face. Blood is splattered across his suit, and he’s scrubbing at his skin with a towel to remove the last few flecks still clinging stubbornly to his face and his hair.
❋ He’s grumbling to Ran and Rindou about how messy the last session was, and how it’ll take him ages to get the blood out.
❋ You tell the nurse to go on ahead, and walk over to Sanzu, who arches an eyebrow at your approach.
❋ “Let me help. This should make it easier, and the blood won’t get into your hair next time.”
❋ Whisking your fingers through Sanzu’s hair, and inwardly marvelling at how silky smooth the strands feel against your skin, you gather his hair up into a high ponytail and secure it with the fuzzy scrunchie from your wrist.
❋ “You look cute like this. You should wear your hair up more often.”
❋ You smile shyly at him, and hurry to catch up with the nurse.
❋ You don’t see how Sanzu’s face turns a bright shade of red as his mind finally registers your words, or hear the choked, funny sound caught in his throat.
❋ Ran and Rindou do, though. And they make no attempts to conceal their amusement once you’re out of earshot. Bursting into loud, boisterous laughter, making weird and grotesque faces, and puckering their lips. Mimicking your voice, and cooing at Sanzu, “Oh, Sanzu, you’re so handsome with your hair up! I’m in love with you, Sanzu! Let’s get married, Sanzu!”
❋ Basically, they do everything in their power to piss off Sanzu. And it works. He flips them off, and leaves in a huff, trying to ignore the sound of laughter grating incessantly upon his nerves.
❋ The next day, you catch a glimpse of Sanzu wearing his hair up, in the exact style you said you’d liked.
❋ And when you smile at him once again, Sanzu has to ignore the fluttering in the pit of his stomach … And the mocking laughter coming from Ran and Rindou by his side.
bonten sanzu underestimating you and accepting your punishment for talking back to you so he ends up being so fucked out that he goes limp in your lap and flops over, burying his face into your shoulder and whimpering as you continue to fuck him through your orgasm, kissing his red ears and nipping at his earrings as your fingers dig into his trembling thighs, jostling him with every thrust. with every tired whimper of “mmm, are ya done yet.. I can’t..” you thrust your hips harder and make sure to hit his abused prostrate, cutting haruchiyo off with pitiful whines and keens
