(I'm sorry, dear...) Mio hid her husband and had a physical relationship with her son. At first she was just a whim. She just wanted to comfort her body, which was lonely and left unattended by her husband, who was only doing her work. But she was unexpectedly compatible with her son and her body, and she was hooked. She loves her son...her son's cock more than she does her husband now. (Oh, I want that child soon) Her affection for her son turned into sexual desire, and Mio waited for the moment when her husband left with her crotch wet.
