How about having a dominatrix be his "babysitter" while you go out on a date? Give him strict orders to obey her as he would you while you're away, and have her make a list of his transgressions (real or imagined) for him to be punished for upon your return. "Mistress Babysitter" could supervise his dressing up and make him prance around to show her what a good little girl you've made him.
Upon your return, you could tell him about your date and punish him after Mistress Babysitter checks off the list of his transgressions. You could also apply a tassled butt-plug to his sissy ass and have him prance around for your Ladyships' amusement. His reward for being a good girl would be a good pegging from both of you. Just a thought for your consideration...
I do plan on bringing in a rigger (who is actually a Dom too). Maybe I can let the rigger have some fun with my sissy girl... create some art for me for when I return. And then all sorts of naughty things can ensue.
Cheers
