Mother and Marilyn and I were talking about the things to do for Marilyn to move in with us. I got a fairly long to do list and not bratty but tried to jest with my mother if I did everything right could I have extra time at breast and her hand that night. Mother smiles but Marilyn reacted very badly and took the few steps to me and slapped me moderately in the mouth and nearly yelled at me that a mamas boy does not talk to his mother that way and try to negotiate for more than bis mother felt was right. I was stunned and eyes welled up but mother was out of her seat and grabbed Marilyn’s wrist and slapped her back and was almost yelling herself when she told Marilyn that beyond spanking she was never to strike me again. Marilyn was cuaght totally by surprise and sat down with her free hand to her cheek as mother got right in her face with a finger and made her repeat the rule. Marilyn apologized sincerely and mother still holding her other wrist lectured her about she was going to be mommie to me but that did not replace her as mother. Mother walked to the sofa and sat down and looked up at Marilyn and said “well?” Marilyn asked what my mother wanted and in a very stern voice mother told her that she expected her skirt up p****** down across her lap. Marilyn immediately protested that mother could not possibly be serious much less in front of me and mother told her that she refused to have me learn that I could be struck without consequences. Mother grabbed her other wrist and told me to walk up behind Marilyn and pull her p****** down NOW. Marilyn tried to pull away and dropped to her knees and pleaded but mother would not tolerate it and pulled Marilyn up from her knees and with mother’s insteuction I made Marilyn lay down across mothers lap and pulled her p****** down. Mother told me to step back and remain silent and mother really put Marilyn through a very stiff spanking with her hand.
