Twilight doesn’t just have an amazing brother – she now had an amazing sister-in-law. But when Cadence unilaterally invites Twilight along on their honeymoon to help her fulfill Shiny’s most transgressive fantasy, will it mean sexy fun times or awkwardness, drama, and embarrassment?

Both probably. It'll be both.

Set shortly after the end of A Canterlot Wedding.

Contains: Mostly relationship talks (if you're just here for the porn skip to chapter 4), brother/sister incest, wet and messy, spit play, and wholesome married group sex.
