Philip arrives home sporting a black eye earned defending his mother's dubious honor from schoolyard taunts. His grandmother gives him a bath and more. Then the nice lady next door teaches him a few tricks. Grandma comes back and teaches him some more. Finally, his abundantly endowed mom arrives and he shows her what he just learned.
Mom's not bashful when it comes to breast feeding her daughter. More then once her teenaged son watches. When he finally races to his room one night she knocks at his door only to find his sheets tented upward at his waist. You'll have to read the rest to know not the what but how it goes from there.
