It has been many years since Golden Oak Library was destroyed during Twilight's battle with Lord Tirek and was replaced with the Castle of Friendship.
After giving the castle to Starlight, Twilight gets word from her friend that she found an old section of Golden Oak basement under the castle's basement.
Twilight returns to her old home and, with the aid of Rainbow Dash, go down in the basement to recover old items that might be worth saving.
But both girls will find something that will change their relationship between each other forever...and all it took was one potion...

Fetish:Futa, bondage, pet play, master and sex slave, magical trickery/mind control I guess, blow jobs, foot job, mind break, dominating, bestiality (well not really but still counts lol)
