Stepmom paying the rent of our house

My stepmother has always been very responsible and for that reason, to keep the well-being of the house and the bills up to date, including with regard to rent, she is capable of anything, including using her ass as a form of payment to be able to leave everything in order... When she doesn't have money to pay the landlord, she texts him and regularizes the whole situation by giving him her round white ass to eat until he feels like cumming in her.
