Slave washing My feet and drinking this water with My spits

Description: I was visiting my boyfriend, his floor wasn't washed and i got my feet dirty, plus after it i was all day long in warm pantyhose, so i want my feet washed. my slave's washing and massaging them very gently in foot bath. i'm in a good mood, so he deserves a reward for his diligence: i'm letting him to drink a glass of this dirty water, of course i'm spitting in the glass. a worthy beverage for this nonentity!
