No one has ever accused him of not being vocal - and John proves that non-point by making a pleased little huff of a noise even as he bites Q's bottom lip again - a little hard - before sucking at it a little, as if to dispel any actual hurt of it.
Unfortunately he's got to breath properly eventually, and so leans back minutely to do so, looking a bit smug.
