Mommy needs to talk to you about how you've been groping your 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, mommy can't even get wet for daddy's dick anymore. She needs you. And you? You need her, yes...but you need more, too. And a good slut like mommy will give it to you, even if she's a little jealous.
