Mama made rule no panties after daddy took my virginity

I came home from school and went to my room to change and notice I didnt have any panties in my drawers. I was stunned as I know I had some when I went to school. I left my panties on that mom had altered into a thong and just changed to my shorts. I know mommy works from home so I asked her if she could do laundry and she asked why she as she just did it. I told her I didnt have any panties for some reason.
Mom told me to come to her and she'd explain but as I went to go sit she stopped me and bent me over like I was in trouble. I protested and said I havent been a bad girl and she said oh but you are and thats why you dont have panties left. She told me to touch my toes and she pulled down my shorts and then yanked my panties off so hard that I almost fell and they tore off me. She said better and now I can sit. Mom then told me that only bad girls wear panties and that the pussy should be free for multiple reasons including air flow to it but most importantly she said men are to be able to see womens pussy any time and should not see panties and that if they do it means youre a lityle girl and virgin. I spoke up and said but you and dad said Im a big girl and not a little girl anymore.
Just as this was happening daddy came home and called my brother and I and said front and center now! As we stood in front of him he told my brother to go sit with mommy and told me to present myself. I knew what that meant, stand tall shoulders forward and legs apart. Daddy then came up to me and said have you complied with the rules of being a big girl and when I didnt know what he meant he hooked his thumbs in my shorts waistband and yanked them down to the floor. Daddy was harsh for a moment since Ive been good and he spent me over and spanked me. I was crying and he stopped and said thats for not answering him and he then spread my ass cheeks and I could feel his breath on my pussy lips. He started running his finger up and down my pussy and didnt feel moisture and spread my pussy lips and said good no moisture that was light punishment. I felt daggers on my ass and turned my head and saw my brother sitting on moms lap but his penis was out and had the lil boner he could.
Dad then said from now on no panties allowed and I will periodically be inspected at random and I better be a good girl. Daddy didnt say I could pull my shorts up and instead told me stand up straight hands behind my head and let my brother look while he told me talked. He told me that he made me and he has the right to my pussy and ass whenever he wanted and that I am to service both him and my brother everyday. I said but mommy does that for bubba and he immediately spanked my pussy and said do we back talk little girl. I got mad and said Im a big girl you said so yourself and then he said act like it then.
