You are dressed as a man by your wife in stockings and lingerie, your penis is locked in the chastity cage, you get an anal plug in the ass and are kept as a pleasure dick slave. You are a 24/7 sissy slut who has to blow cocks and swallow cum.
The sissy slut did not want to swallow the cum at the last client, that does not work at all and so she gets a lesson in cum swallowing from her mistress.
