I have a special test for my sissy today; fully made up and locked in her dress she presents herself to me. I have decided to host a little get-together of my female vanilla friends to demonstrate how useful a male can be when he is transformed into a sissy maid. At this party I will be expecting my sissy to serve beverages to all my friends and I have attached a serving tray to assist her in doing so. It is important to me that my friends can actually see the benefits of having a sissy in their life, and what better way than being made to serve them all night! Before the party commences I have decided that my sissy requires training in her new role of servitude. I require her to be able to serve all females under the most humiliating of conditions and without a single drop being spilt. I decide to gag her with an o-ring gag to ensure that she remains quiet during her use and then spit into it to remind her of her new place in life. Whimpers of despair can be heard from my sissy as I order her to lift up the tutu and expose her panties and holdups she is wearing. I lower the panties down and expose her sissy clit- little does she know that I intended to torment it using electrics! I wrap the rings firmly around her clit, pull her panties back up and make her lower her tutu. I place my glass of champagne on the pink serving tray and increase the intensity of the electrics- the sissy starts to squirm in pain as each pulse makes her little clit twitch in torment. I then order my sissy to pace back and forth to ensure that she can serve my champagne with her clit being electrified. Now that I am happy she can take a medium level of shock, I ramp up the estim level to high and make her pace back and forth again. My sissy maid struggles, the glass moving slightly as her clit throbs with each volt passed through it. I sit back and laugh admiring my creation performing for my amusement and soon to be performing for many of my friends! Happy with the results I decide that one last test is required - how much can this sissy take? I turn up the electrics even further and she cries out in pain, her clit is spasming from the sheer amount of volts being passed through it. Naturally ignoring all of her complaints I order another number of paces to be completed with the champagne glass on the tray, she struggles and you can see tears of desperation as the glass wobbles from side to side. Pushed to the limit I dismiss my sissy fully satisfied that she will be able to serve all my lady friends this evening to her full potential.
