It doesn't take a major injury for Hirato to find an excuse to show Akari affection. It's fun to mess with Akari, and any sort of injury just gives Hirato a reason to show concern, fake or not. After all, the blonde doctor is just so easily agitated.
Which is why Hirato often finds himself in Akari's office when there is nothing crucial for him to take care of. If Akari is not performing routine checkups or surgery, he is almost always in that office of his with so much paperwork that Hirato shudders to imagine the hours it must take to fill all of it out. Being a captain, the dark haired man is often able to pass down his paperwork to less important members of his ship. Akari has no such luck, and it entertains Hirato to be able to observe his doctor hard at work filling out forms and checking medical records.
It can be a very dangerous job at times. Akari flinches with a sharp intake of breath as a sheet of paper slices the tip of his pointer finger. He licks off the dot of blood that gathers so as to not get it on the rest of his work, but Hirato is unwilling to let such a horrible injury go untended. He takes ahold of Akari's hand and plants a gentle kiss over the small nick, letting his tongue lightly brush against the skin.
"Stop that at once," Akari demands, but when Hirato just lifts an eyebrow, he is forced to merely grit his teeth and thanks his lucky stars that it was his left hand which was cut so he can continue his work while Hirato continues… whatever the hell this is. By the way Hirato grips his wrist so tightly, the doctor knows he couldn't pull his hand away if he tried.
But Akari grows more and more flustered by the minute despite his attempts to ignore the other man, and though it doesn't show in his face, it does show in the impatient tapping of his foot and the narrowing of his eyes. Hirato's tongue is frustratingly sensual against his skin, and it trails along the length of his finger when a small rivulet of blood drips down across the lines in his skin. When Hirato takes his entire finger in his mouth and sucks, it's the final straw for Akari. He pulls his hand back forcefully and pushes his desk away from his chair. "I'm going to take my break now," he says stiffly, standing and exiting so hastily that his lab coat flows out behind him.
Yet he isn't quick enough, and Hirato finds immense humor in the way the tips of the doctor's ears burn red even as he flees.
