Late one night, Twilight finds out about a secret shipper.
A shipper with a deliciously naughty voice and cute little fangs, who doesn't want to take no for an answer.
I don't even know the 'official unofficial' ship name for Twilight Sparkle / Nightmare Moon.
- Twightmare Moon is funny? But I don't think most people would go for it.
- "Moonlight" is a fanname for a minor character late-ish in the show (s5?)
- bats (who has never seen this story) suggests "Spicy TwiLuna" and "Spicy Tuna" 
...
Author's Note elaborates a bit on how parts of this story aren't really good wooing technique for real life.

And the Tuna shippers rejoiced.
Read this on the recommendation of my friend, the other commenter below me, who said to me, and I quote, “Did you commission this? Lol[.] In all seriousness, this looks like something you might enjoy. You like spicy Tuna, right?”
The Nightmare Moon x Twilight Sparkle (or Twilight Sparkle x Nightmare Moon) ship name is Moonlight or Twimoon... Trust me, I’d know.
This was a very amusing read. A bit short, but good work.
Aw man, this was just really cute.
A ship as old as FIM
OH NO, MY PARTS!!
Fun story. Kinda short. But nice to see more Tuna.
Awwww.
