This story is a sequel to Eventide

Every full moon, Fluttershy reverts to varying degrees of her Flutterbat incarnation. Sometimes it’s mild, sometimes her marefriend Sunset has to help contain her primal urges.

It hasn’t made for an easy relationship, but Sunset won’t back down.

Continuity: Equestria 616

Pear Butter sits to write her new daughter a letter to be opened later when they can laugh about it. Being a parent is a frightening prospect even on her second foal.

But it’s still sealed decades later.
