Step-Mommy needs to talk to you about how you've been groping your step-sisters. It's not right, not when she's here to take care of you. Besides, she needs to teach them before they can handle a cock like yours! Gosh, your cock is so nice, step-mommy can't even get wet for step-daddy's dick anymore. She needs you. And you? You need her, yes...but you need more, too. And a good slut like step-mommy will give it to you, even if she's a little jealous.
