There are a few stories called this (or variations of it).

What I want to know is:

Why are none of them Night Light x Shining Armor incest stories?!

Dang, I wish I'd thought of that before I'd used that title on a ShinyMac story.

Oh well. Too late for me now. Perhaps others will learn from my mistake.

You do realize they're not really related, don't you? They're just actors.

and people who like incest fics,
is a fraction of a fraction of the reader fan base.

Because ew.
