Mother artist shares her model with her daughter's whore

This mature woman has always had a special whim with the boys who come to her house to pose naked while painting them. It is tradition that I give them a blowjob as a special payment for the effort they make. This time her daughter's whore hunts her with her hands in the dough and decides to share with her the art of eating tails. Then the daughter is hooked to the model and fucks him, at which time the mother arrives to make a trio of the most vicious with which the uncle penetrates them both as true foxes.
