Things I have had characters say during sex in fanfiction
(I swear they all made perfect sense in context)

“What’s a parrot?”
“You just assigned each piece a number and followed a sequence from pi! You didn’t even start more than twenty digits in!”
“Steroids can make you stronger, asteroids can kill you”
“Alan-yes”
“I mean, if you want integer overflow…”
“Oh, ye of annoyingly great and powerful faith.”
“For decimal. Then, these plus th-the other six– for hexadecimal–”

…Edit: Went back and checked and yeah, the dialogue during sexytimes was never nearly this fun before I started writing Tron fic.
My Kirk/Spock and other older stories are weird as fuck, but this fandom is on another level. I do not regret being here.

I feel the need to add: most of these were actually directly talking about the sex.

The “asteroids can kill you” one… literally WAS a sex act. The big O in Tron-fic is for Overload, and she was trying to crash/overload her partner with an excess of information, and the information she chose was puns, because it gets more data through at once via double meanings

(…also because both of them like puns, probably more than normal)

(….those two characters are both self-inserts, and idk what that says about me but… I am ok with it)
