Mistress Sidonia hosts a wonderful summer party in the beautiful Mansion gardens with Mistresses Lola, Evilyne and Annalisa. In part 1, the Mistresses have some afternoon tea, attended by the maid and slaves, they are soon playing with them, plenty of humiliation and CBT as they are introduced and suitably chastised. The ladies then retire to the paddock and enter the pony chariot racing completion as the slaves are made to pull the Mistresses around the racing course in different rounds with the loser to face a special hard punishment.
