Genitals molested by sister
I am 20 yrs old boy. I have two sisters there age are 15 and 17 yrs. My father lives abroad for earning money . So most of the time we live with our mother .my mom is a dominating female. The problem has started 5 yrs ago when I have a quarrel with my sister and I has beaten her badly . She started crying and went to the mom . And she told this to my mom. Mom became very furious on me and mom asked to my younger sisters for squeezing my testes if I ever try to beat them or fight with my sisters in future. After some days I have another dispute with my sister and I have slapped her very hard. Surprisingly she reacted very violently and grabbed my testes over my trouser and started squeezing it very hard. I screamed with pain and I pleaded to her for leave my genitals. After some minutes she leave my genitals and became very happy by realizing her first victory over me since childhood. After that incident whenever I has any quarrel or dispute with my sisters they starts squeezing my testes. And forcefully remove my trousers and underwear. And makes my genitals totally nude and then the squeeze my testes and twist it very hard.. Sometimes they do this in front of my mom also. I have asked my mom several time to stop this humiliating punishments given by sisters after taking consent of my mom. But she refused to stop these things. They not only watch my bare genitals molesting but also enjoy it. It is very embarrassing to become nude in front sisters and mother. And they molest my genitals in a wild manner this give a lot of pain and humiliation. How can I stop all these things in my house against these dominating female. What should I do to stop these things.
