Son comes into the kitchen. Mom in her robe coffee. She says, "All hot and sweaty from your morning run? Good, I want you that way." She lets her robe drop to the floor, and says, "Don't worry about your father, he won't be up for another hour." She lays on the floor and says, "Fuck me, fuck your Mother with your hot young cock." The son gets on top of her and she actually smiles and says, "That's it, fuck me. Fuck me with your hot sweaty body, I want my son's cock in me. Make me dirty, fuck your mother and make her all sweaty and dirty." When she cums, she cries out and he gets off.
