Even though she has a husband, stepmother Miki still demands sex to release her sexual desires. Whenever she sees her son's face, her sadistic blood boils, and she tramples on his face and dick, enjoying his reaction. She makes him touch, knead, and lick her proud F-cup breasts, and orders him to do as she pleases, and her timid son obeys. Miki becomes even more excited, sucking her son's penis until it's covered in saliva, and even digs her tongue into his asshole, attacking him. Still in heat, she straddles her reluctant son's cock, and while making him knead her big breasts, she lewdly shakes her hips, and as if it were natural, she demands that he impregnate her instead of her husband.
