After his father left, my son had to take over for some of the roles in the house. He doesn't seem to mind. For everything he fixed, a blowjob that night. Every bill he helped pay, my pussy was his. We heard a noise in the kitchen one night and when he got back from checking what it was, I let him fuck my ass. It only seems fair to repay him for these things. I understand my roles too. I've got to be a good mother but I've also got to take care of my alpha male.
