[MF] Mistress gets what mistress wants ?

It started while I was at work (am essential). We were just texting trying to decide what we would do tonight when I got off work. We start talking about watching a movie, so I ask her what she’d like to see. She immediately shoots back “you cumming”. Before I know it I have a list of instructions for when I get home.
1: kiss your mistress hello
2: shower
3: change into the clothes chosen for me by mistress

I bolt through the door and fall to my knees for my mistress. She picks me up off the ground after a few head pats and kisses me gently. I hurry through my shower to find what mistress wants me to wear laid out on our bed. It’s a cute thong with a flower print. A little tight on me, as mistress is smaller than I, but snug enough to make me feel like the little slut I am for her.
