On a unplanned trip to mares, colts and beyond, Ponyville's only adult entertainment shop on her eighteenth birthday, Berry 'Pinchy' Pinch discovers something that she had never expected to find out about her mother.

On the cover of a pornographic tape, alongside Fleur-De-Lis, is Berry Punch, looking up at her with 'do me' eyes.

After confronting her mother about the tape, Berry suggests something that Pinchy wasn't expecting - that they watch it together. After all, Fathers and sons do it, right? What's the worst thing that could happen?
