Life after the fall

With the rules set, everyone fitted into their roles quite nicely, Sam started doing exceptionally in school, Pam became extremely successful due to her years of experience and Mam kept firm control over the reigns, whether that be setting bedtimes, having friends over, making Sam eat his dinner or being in control of Sam's orgasms. Usually, these orgasms would be on Mam's supermodel milf body but when Sam gets especially childish Mam will sometimes give in and stroke him off, going further and/or deeper depending on how good Sam has been behaving and how best he can put the moves on her. Still, for the most part, it is only Mam and Pam who engage in sex, anywhere and everywhere in their house, very frequently, leaving Sam to hide and masturbate to them or act like he doesn't notice while he touches himself.
