Mistress Sidonia's slave is delighted to be informed that due to his good behaviour he will be allowed to give oral pleasure to one of the female subs, however his initial eagerness soon wears off when he realises that the female sub is Mistress's TV dolly and it is her very large clit that needs the pleasuring! He is reprimanded for initially refusing to comply and not recognising the dolly as a female, but with a little persuading he is soon having his oral skills trained. As a final treat, Mistress puts on a big strapon and the slave is given a hard spitroasting.
