This is.. unexpected.
Not unwelcome, to be sure, but unexpected. His hand shifts a little at that small smile, the one that always sends his stomach into freefall as he leans in to kiss him. It had been ages since they'd touched, ages since anyone touched him with anything other than clinical detachment and he sinks into that kiss with a quiet, pleased sound.

He isn't thinking about anything else now, just familiar lips on his and his hand sliding from Leonard's waist to his back to draw him in that much closer.
