Are you ready to serve Mistress with all of your holes? She wants to use your sissy slut self for her strap-on pleasure. First, she'll use your mouth, letting you get her toy nice and wet. When she's through with your mouth, she'll watch as your finger your own asshole for her, stretching yourself out nicely so you can take her cock when she's ready. Once you've jammed your pretty little asshole full of your own fingers, Mistress bends you over her desk and fucks you from behind. When she's had her fill of you, she takes her cock from your ass and has you take it in your mouth to finish.
