To be honest, I've never been very much impressed by sporkings that simply stick vast amounts of sexual innuendo into a fic; you can do that with anything if you happen to find that sort of thing funny, so it comes across as pretty lame critique.
As opposed to something like the old cliché of children looking conveniently identical to their genetic fathers (for added interest, mix with a spot of adultery :-p)

The main complaints about the story seem to be anachronisms and lack of plot (beyond Unresolved Sexual Tension).
