You have settled right into your duties as a Sissy Maid for your distinguished Mistress. In fact, she has been so impressed with your performance that she announces that it is time for a uniform upgrade. This will indicate an upgrade of your rank in the hierarchy of her sissies. It is quite an honor. She has your strip out of your old uniform and slowly has you adorn and model each new piece of your attire. The first item is a new pair of black, opaque stockings, which she has you then attach to a black lace garter belt. Next comes a new pair of red, ruffled panties, topped off by a penis gag for your mouth and a pair of clamps that you are instructed to wear on your nipples. She then informs you that while she cannot remove your chastity cage, since you have performed your duties so well, she will offer you some release. She lubes up a finger and slides it into your ass. As she begins to milk your prostate, she rubs your clittie in it's cage. The brief, fleeting sensation and warm of her hand running over your caged clittie while she fingers your ass is amazing! She tells you that you have such a good girl an that she wants you to cum for her while your clittie is locked up. You do as you are told and milk your cummies into a cup held by your Mistress, which she then raises to your lips and tells you to swallow from. Being the good girl that you are, you lick it all up. Even Mistress takes a little sip. She then sends you on your way to clean up and continue with the preparations for her highly-anticipated Sex Ball.
