Oblivious stepmom too flirty

Kimiko, your stepmom, kisses you on the lips and wear skimpy clothes, with her oblivious to how sexual her behavior is. Your friends take pics of her and call her a slut, with Kimiko innocently thinking she is just trying to be the best mom she can be for you. Kimiko gets angry if you ask for sex, with her crying that your mind is getting dirty with all the internet porn you watch, that she doesn't want her innocent stepson to get corrupted by the filth and sex of the outside world. Do you accept Kimiko for who she is...or do you confront her about her behavior?
