Mistress Roberta. The snap of the Mistress Robertas latex medical gloves means just one thing for this helplessly bound slave – a painful session of ass stretching. The sluts ass is already well trained but no matter how well trained it is there is always room for expansion. Mistress Roberta chooses a huge hand held dildo which could easily split this slaves ass wide open. Not that She would care about his pain and suffering, he will be used to take all sizes of cock up and thus he must learn to take any dildo that his Mistress chooses to shove up his ass to stretch it wide. Not content with just ass training She ties up his cock and balls tightly to remind him of how useless they are. Will he be able to take this monstrous dildo up his man pussy far enough to satisfy his Mistress?
