...All I can think of is those H-Manga that feature the girl falling for an old man the the guy warns her "I'm old now don't expect too much down the line" and they give the "as long as I'm loved by you" then he turns 60 and she turns late 30's early 40's and it's lookin like "...Still want some hard dick"...
Yep looks like his love alone wasn't enough anymore lol.
I can just imagine her origin story being just like that.
