My stepmother gets horny and comes home every night. Each time, she takes off her clothes and invites me to bathe with her. Even though I feel guilty toward my father who's away on a business trip, it becomes harder and harder to resist her—especially with her big, sexy figure right in front of me. I can't help but want to bury my face in her large, soft, jiggling breasts. We can't just stay mother and son. One night, as I'm sleeping in my room, my stepmother appears completely naked. I know it's wrong, but the lust building in my lower body becomes impossible to control. In the end, the two of us give in to forbidden incestuous sex.
