Is she yawning in the first panel of page 5? If not, it's the most bored looking orgasm I ever seen....
Dig the rest of the stuff, but I think the first page is the most solid. Excellent pacing, dig the angles. It's like a refined Ben Templesmith. The other pages look a little hurried, but still look good. I'm not exactly sure what happened to the guy on page 4 though. Too many things pop in my head for what happened, for me to feel satisfied with the flow of the story.
