There's nothing like a sharp face slap to wake your slave up, I find it gets a quick response. After returning to the house he shouldn't need to be told what's needed. He should be on his keens ready and eager to please massaging and soothing my feet. His duty should direct him to knowing how to honour and please his Mistress. He is learning thought, see how he takes my foot as deep as he can into his eager mouth, searching out the cute little gaps between my toes. Seems a face slap or two is quite effective.
