whenever rin was extremely concentrated on something, his tongue lolled out to the side absentmindedly. you always associated this trait just as a dog would have its tongue out.

"rin..?" you started, a confused expression on your face. "what are.. you doing..?" shortly put, he was licking your neck.

he wasn't doing anything even sexual. just... licking you. like a dog would. "are you a dog?" you said teasingly, not expecting an answer from him.

"woof." he grunted out, causing the tip of his ears to turn a shade of red, before resuming his licking.

ah.. don't dogs lick people to show affection and to get attention..?
