Very unmistakable, actually. Acutely so. It is difficult to be controlled at this hour (whatever this hour might be) of the morning, but McCoy is a man on a mission. He has to thank her properly for... well. Everything.

And he sort of loves that sound. He'll have to see if he can get her to make it more often. Satisfied that he has managed to bid good morning to her breasts, he slips further down, exploring the edge of her ribcage and the hollows of her abdomen and he pauses to dip his tongue into the hidden crevices of her belly button and slowly lower, trying not to miss anything at all.
