I thought folks might enjoy seeing some author notes about “Whoops”:
“Whoops” contains the longest continuous sex scene I've ever written. This was not my original plan; I had intended to gloss over some of the encounters and focus on others. But in the course of writing the story, I couldn't bring myself to shortchange any of the Loud sisters (except Lily, but most readers are probably okay with that).
In the original draft of chapter 1, I had Lisa say that the menstrual cycles of women who live together tend to synchronize (something even my wife believed was true). But Fairy Slayer, who betaed “Whoops” for me, pointed out that that's a myth, so I rewrote Lisa's dialogue as appropriate. (This was not the first time that FS pointed out a scientific inaccuracy in one of my stories; he also noted a fallacious statement about black holes and Hawking radiation in “Dark Dreams, Forbidden Fantasies.”)
The idea to make Lisa's comment “I can do a lot of things” a recurring line also came from Fairy Slayer.
The “Amazinger T action figures” that Lincoln plans to leave to Clyde in chapter 2 are a reference to the Mazinger Z manga, anime, and toys from the 1970s. (I included this line because Lincoln seems to have a fondness for toy robots.)
Boyz Will Be Boyz, whose members’ voices Lisa uses to lure the other girls away from Lincoln's door, is the band from Lori's first concert in the episode “For Bros About to Rock.”
Lincoln uses a different position with each of his sisters: Lori, cowgirl; Leni, missionary; Luna, on their sides; Luan, sixty-nine; Lynn, various (as they wrestle for who will be on top); Lucy, sitting on Lincoln's lap; Lana, reverse cowgirl; Lola, sitting on the dresser; and Lisa, doggystyle.
Lincoln's discovery that Lucy has blue eyes was a cheat on my part, because on The Loud House, none of the characters’ eyes have irises -- just pupils and whites. This style of drawing eyes was also used in Gravity Falls.
Lisa's comment that “most lagomorphs do not have an estrous cycle” (in response to Lana shouting “Fuck my butthole! Fuck it like a jackrabbit in heat!”) came to me because of a Zootopia fanfic I had read in which Judy Hopps goes into heat. At the time, I thought, “Rabbits don't do that, do they?” so I looked it up, and indeed, they do not. Rather, female rabbits ovulate whenever they have intercourse, which is how they can crank out so many little rabbits.
The lordosis reflex that Lisa mentions in chapter 6 is a behavior common among mammalian species, in which the female gets into a sway-backed body posture in preparation for intercourse. Humans don't actually have this reflex, but given both Lisa's substantial experience with lab animals and her desire to have sex “in the fashion commonly associated with Canis familiaris,” I figured she might enjoy including it as role-play.
In chapter 6, when the girls start to freak out upon realizing that they didn't use any birth control when they had sex with Lincoln, Lisa replies that “There's no need for hysterics.” This is a bit of word play on Lisa's part, as the word hysterics comes from the Greek word hystera, meaning “uterus.”
My initial reason for making Pythagoras a mouse (rather than a rat, which, to my mind, seems like a more appropriate subject for a study of intelligence) was that there was going to be this bit of dialogue at the end between Lincoln and Lisa:
“So, how did your project with Pythagoras turn out?”
“I'm afraid the experiment had to be terminated. The research ethics committee wouldn't approve it, on the grounds that hyper-intelligent laboratory mice always try to take over the world.”
As amusing as this Pinky and the Brain reference might have been, the implied killing of Pythagoras seemed like too much of a downer for the ending of this light-hearted fic, so I didn't include it.
Finally, if you liked this story, stay tuned: I've got a new fic in the works titled The Loud House After Dark.
