Every day, the father-in-law's lust grows for his son's wife's G-cup big tits. He can't suppress his desire to grope, suck, and fuck those overly voluptuous breasts to his heart's content. One day, his son's business trip is decided, giving him a chance to be alone with his daughter-in-law at home for three days. He attacks her as she dozes on the sofa, exposing her breasts and repeatedly caressing and licking them. He then strips off her panties and torments her with hot cunnilingus. The awakened daughter-in-law resists, but he forcefully shoves his throbbing dick into her pussy and makes her cum repeatedly. After that, she is continuously creampied by her father-in-law, gradually becoming addicted to him. Her body is transformed into one that can't be satisfied by her husband's limp dick.
