The stepson came home to find his stepmother on the couch, showing off her enormous ass. One day, my stepmother argued with her cuckold husband because she'd found him a lover who was his best friend. She was exhausted on the couch, but her stepson took advantage of the situation to stick his huge cock in her and make her happy.
