Sisters human footstool and shoe licker

Description: For the first time, sisters mistress harley and mistress lilith use their human footstool, as they relax watching tv and playing on their phones.  it's not long for the human footstool to start and shake under their feet whilst he's on all fours.  mistress lilith starts to get annoyed and kicks him.  eventually they order him to lick the soles of their trainers clean after walking around all day.  they deliberately stood in as many disgusting things as they could and laugh at him licking their shoes.
