Loveless, Seimei/Ritsuka, the only clean thing
It wasn't odd for the brothers to take a bath together-- they had for as long as Ritsuka could remember. Nor was it odd for Seimei to gently wash his younger brother's back and for Ritsuka to take comfort in the touch.
It was odd, however, that this time Seimei's hands seemed to be venturing lower than usual.
"Seimei, what are you doing?" Ritsuka asked as he felt a hand on his rear, turning slightly to shoot his brother a sidelong glance.
"Washing you," Seimei replied nonchalantly, though he had a sort of smile on his face that hinted at something mischievous.
"But you don't usually--" Ritsuka began to protest, but stopped abruptly as a finger probed inside him, ever so slightly. "Seimei?"
And in the blink of an eye, Seimei was no longer touching him. In fact, he was out of the bath, quickly drying himself off. Ritsuka could do nothing but blink in confusion as Seimei wrapped a towel around himself and reaching for the door.
"Keep your ears," was all he said, in a voice no louder than a whisper, before shutting the door behind him.
Ritsuka sunk into the bath, hiding his red face, and stared at the door wondering if Seimei was beginning to think that his own ears were a bad thing.
