I feel like the first page should go at the end or something. The rest of the pages are how she's teasing him with greater and greater bluntness, the first page feels like the page he finally breaks down.
Unless the first page was what awoke her itch, and the rest of the pages are her trying to get a repeat performance, but that's not really hinted at anywhere.
Either way, the art is superb and expressive, and the situations are ridiculous, humorous and make me want to see more.
