This interpretation is also more than acceptable! Perhaps even in combination with the one I suggested? Reading a story to an adult to help them sleep is cute enough for Fluttershy, and weird enough for Discord.
Fluttershy has been weirder things since Discord asked if he could add some variety to her physical form, and now that they are married some of his ideas can get get downright Lovecraftian. She doesn’t mind a bit as long as he turns her back before anything where she might scare anyone (including an animal).
She thinks he looks cute in echolocation, but not NEARLY as sexy as his blinking was when he mixed a little Firefly(1) into their forms.
(1) The species, which I capitalize for sapient variations, not the sci-fi series.
