[It's a strange feeling, having someone smile while their mouth and your mouth are so close together. Not unpleasant in the least though, and that she's so obviously approving of where he's taking this helps a lot. He'll just distract himself with the kiss while trying to work out how he's supposed to tackle this final step.
Finally he decides to just go for it, gently tracing the curve of her breast with his fingertips. The touch is light, barely there, so much so that you could almost argue that it's not touching at all. He moves up towards her clavicle, where he finally adds some more weight to the touch, palm pressed flat over her heart.]
