Oh fuck, Master's home and you didn't do your chores! Meaning, the laundry, cleaning, cooking, ironing, recycling, and silver polishing (the silver in question being the lovely silver butt plug on the mantle). Whatever are you to do?
Don't panic. Just expose yourself like this and maybe he won't notice the massive mess behind you. Thank goodness the one thing you didn't forget was the brutally intense workout program he assigned to you. If you follow up this greeting pose by lovingly and greedily pleasuring him with your mouth and ass and hands and toes, you stand a chance of avoiding serious punishment. Although as soon as you're done pleasuring him with your mouth and ass and hands and toes, you're in for it.
Oh wait. You like punishment. Enjoy!
