The kiss was slow and sensual, Sherlock's clever mouth nibbling at sucking on his lip and making John's knees quiver. A low, soft noise rumbles in his throat and he kisses back as best he can without messing up the flow of the detective's actions, sliding his hands down to appreciate the curve of Sherlock's arse before sliding up under his shirt to grip at warm skin and shifting shoulder blades.

John let himself be properly kissed, continuing his purr of appreciation as they circled in swaying steps around one another, pressed close and tight, only stopping when the bedding he had pulled to the floor brushed against their ankles. For an easy stumble or push or gentle guiding down should the need arise, since the desire was already there.
