I suppose, there were a few moments that could be rewritten. I just don't usually post until after I've undergone at least two revisions.
I don't either. 16 Ways was an experiment in posting straight-up first-draft material, without significant edits. I wrote it as I went and didn't edit for inconsistencies or plot drift or anything. My other stuff is generally more polished by the time it sees the light of day.
excuses, excuses... But I liked the raw feel of it as a whole.
Good; I'm glad it was entertaining. And the ending will be punched up to match/exceed the rest of the story before the tale is through, have no fear. 
Can't, or won't? 
But I can also see that there was no sex in there. I can't say how I feel about it.
Just for you, I will add one more line of dialogue at the end:
"Well, that was fun," I say to Dr. Teeth. "Wanna fuck now?"
"Well, that was fun," I say to Dr. Teeth. "Wanna fuck now?"
That would make the ending so much better.
