I've read Unexpected Expectations before, and found it to be a mixed bag. Haven't read the other two, but if they're just Lemons and Yuri, then I don't think I'll bother.
Well, Perils 1 isn't just a lemon. As it went on it focused less on the sex and way more on the hilarity of Yuuno's situation, in which an Old Belkan marital aid malfunctioned and sent Nanoha and Fate into overdrive after Yuuno.
Larry, Moe, and Curly damage the hell out of each other, but come off no worse for the wear. Biology doesn't work that way! But out of curiosity, what part of biology didn't work for you?
Be careful with that linking. NSFW links are still forbidden outside the restricted section. I would advise deleting the links or moving them to the restricted section (even the people who only quoted them.)

At the end, there's a comment about how Nanoha and Fate are pregnant with a ridiculous number of children, because they screwed Yuuno so many times. Reproduction doesn't work that way. Again, it wasn't very funny to begin with.
The "Emperor" I was referring to was the God-Emperor from Warhammer 40k. A more popular one that's been going around is swearing by "Faust," referring to Lauren Faust, creator of My Little Pony: Friendship is Magic. It's generally only Bronies who do this, though. LOTR fans sometimes swear by Eru Illuvitar, which is basically the Judeo-Christian God in Middle-Earth. The Random Number God and ROB (Random Omnipotent Being) are loved and hated equally, though the latter is usually only used as a plot device. The Status Quo is also rather hated, but recognized as being all-powerful.
These are but a small handful of "gods" that are revered or feared.
