My stepfather's wife is teasing me about my stepfather. Please forgive me now...

My father-in-law Tetsuro, who lives with me, has become a bit of a joke lately, and has often caused trouble to her son's wife, Kotone. However, Tetsuro takes advantage of this and pretends to be wrong with his late wife Setsuko and attacks Kotone, who is currently taking a bath. Having gained a taste, Tetsuro licked and devoured Kotone's pussy using the same technique in the event that her son was away, and finally made the mass of desire enter her vagina. Without being able to tell her husband what she had done with Tetsuro, she is repeatedly convulsed and orgasmed as her father-in-law's cock is tortured.
