Completely defenceless strapped to the education chair, the sissy first gets a gag in her mouth and then the fucking machine is applied to her fuck hole. What comes next can only be described as extremely sadistic because the mistresses visibly have fun with the clitty of the poor defenceless sissy.
The sissy was allowed to spend the night in the cage in the studio and now the mistresses like some fun with her, first her so already erect little cock is locked in the chastity for the pleasure of the mistresses and then she is strapped defenselessly on the punishment chair... what then follows can be described as real evil for the sissy.
