Yes my mum was involved, whilst she never sexually abused us herself, she facilitated it for money from others. Hope I'm making sense.]
It seems to me like your mum is probably looking out for only one person's best interests here, and it's not you, or your brother, or the other potential victims, including your sister. She is quite probably only thinking of herself.
You don't owe her anything. You don't owe him anything. You've carried the burden of their acts for your lifetime. You've carried their secrets for long enough. I can only guess at the toll that must take on you. One day, I hope you are able to scream that enough is enough. You're very brave for speaking out. I truly hope you can break the cycle.
