It's Hearts & Hooves Day, and Silver Sickle has eyes for only one mare: his sister, Copper Crescendo. But how can he tell her? What will she say? And will she let him pound her in the butt?

The concept for this came from SNL's "D*** in a Box" skit, as well as image #2228956 (explicit) on Derpibooru. Original characters are owned by Pony Stark.

Contains: M/F, incest, fellatio and anal sex.

• Written, edited, pre-read (read "fapped to") and left unfinished by Arkadios, with initial input from Sollace and feedback from various members of the Adult Writers Discord server.
