A large part of becoming a true sissy slut is obedience and submission. If a man says bend over, you bend over. If a man says open your mouth, you open your mouth. It doesn't matter how you're feeling that day or if you want it. The man is in charge of your physical body, that is the essence of a true slut.
Because of this you'll often end up doing things I'm sure you're not completely comfortable with. Have you ever been fucked in the ass in the bathroom of a nice restaurant? Have you ever sucked off a man in the back of his pickup truck? Or how about given a handjob in a park behind a bush? Don't worry these will all become common place in your life soon enough.
One thing about you being a slut which we haven't covered is clothing. If you're wearing normal mens clothes, it can be extremely time consuming to disrobe in preparation of a fucking. When your man wants it, he WANTS it, so those are precious extra seconds spent removing your pants. Thats why I think it's best that from now on you wear skirts all the time. But it would look a little strange to see someone wearing a skirt with a men's t-shirt wouldn't it? So it's probably better if you just dress completely in women's attire from now on. I'm sure you've got something around here, don't you?
*I begin looking through your drawers once more.*
Here we go! Put on this skirt and top, if you have any stockings, heels, or anything else that I couldn't find, put those on too.
