When your mature stepmother is craving sex and you don't have the balls to say the words stop it or you better stop it, what do you do? You tell her she's wrong because mature women shouldn't be able to go into love with someone who is under the law. Even if she loves you (and many women do nowadays) saying "stop it" in front of her daughter isn't going to fly with most mature women. Instead you might get her to ask you if you could give her a massage or if you could make her night with her hot and bothered tonight..
