Cherry Lips (Something With A Kick)
The sweet sugary taste in the creases of her mouth gives her away. She's electric on his tongue, like a ripe Raspberry that's bursting across his taste-buds; sharp and tangy, and, Oh, he wants more.
He needs her mouth harder, to feel the bruise that will blossom pretty as a flower on his lips and he wants to see the same blush on hers.
It's so hot in that little breathy space between their mouths, he knows River feels it, her eyes are blown pitch.
Later - when kissing his wife is not so urgent – he will thank Jack Harkness.
