Twilight intended to save Celestia from her imprisonment in Tartarus, but failed and was subjected to a most unusual torment. For the rest of eternity, she will live and die as an office lady whose breasts and ass grow uncontrollably. She will explode after a week and then reincarnate in the same circumstance, memory barely intact, to re-experience the same orgasmic, unending growth that killed her before. She’s doomed… until one day, she meets you, the glorified wage slave who happens to be the new master of her now former teacher.
