Training, once ingrained, is something that can nearly never be turned off, he's discovered.
True, with time, and without practice, one can slip. It happens to everyone - you get complacent, lazy, and it catches up to you.
He is too proud for such a thing to happen, and yet it has once or twice.
But at the same time, there are some things that can never be truly turned off.
For instance, that awareness of his. Even in the appearance of deep sleep, he is aware of every breath of air, of every change in the environment. An ant crossing the floor could not move in his room without him being at least peripherally aware of it.
But more than that is the lovely, lissome, slender form next to his. Her heat, her tender touch, her soft breathing. The smile on her lips, the feel of her gaze on him.
So many things to be aware of.
He had, for himself, never considered having someone this close - it had in fact not seemed a possibility to be looked for, and yet it had found him.
He's had lovers, of course, but never anything serious...never anything he had seriously considered to be lasting, never one he had wanted for his own, to curl in close to by night and be delighted to find there at the first morning's light, when he always awoke.
And so it is that his dark eyes open at her words to meet hers as he turns towards her in the bed they've shared...words he has himself held in his own thoughts. Sacred words, not often spoken in his native tongue, by the people he comes from...and all the more precious, all the more sacred for that.
His own voice is a soft, warm murmur as he wraps an arm around her waist to pull her intimately close to him, his lips brushing hers as he speaks to her softly.
"Ais***e imasu, Michiko."
