Goddess Sydnie is having a self care day which often involves taking care of Her perfect feet. She also has a sub installed in the bathroom for this exact purpose, as he's expected to provide foot massages and just in general be a receptacle for any waste that comes from the process.
Well, She asks for a foot massage early on and his performance is abysmal, so no more free hands for him. Exfoliating Her feet is the focus now as he's going to need to take some lessons before receiving another opportunity. Now he's just going to eat foot dust, and quite a bit of it!
The sub can barely open his eyes there's so much dust falling into his face. Sydnie enjoys his degradation almost too much, and also knows it's a privilege for him. He needs to do a better job in the future if he actually wants to be fed something different!
