Reika, a stepmother who comforts herself while thinking of her late husband, kisses her virgin son who was watching her masturbate and says, "I'll teach you." After teaching him about the female body using fingering, cunnilingus, and toys, she rides him and shakes her hips in lust! From that day on, her son, who had become sexually awakened, began to desire his stepmother... Even with a blowjob, he is not satisfied, and even though she knows it's wrong, she accepts her son's dick... They suck each other in 69, and then he thrusts roughly from behind, climaxing with an incestuous creampie!
