Need help quick! My sister has gone crazy!

So... I am 12 years old. I live with my dad, my mom died from cancer when I was 5. My sister is 16. One evening we are watching tv. Im texting somebody, shes texting somebody, everything as usual. Suddenly, she jumps on me, and kisses me!! I pushed her off, and shouted: "NO!" She ran crying to her room. (We share a room). After 10 minutes, I walked in the room, and she was still crying. I sat by her, and talked to her. Then I just went to my bed, and fell asleep. The next thing I know, she is riding me!!!! Disgusting!! I pushed her off, and ran to the shower. Now I just dont know what to do ?

k well I think she needs help, tell your dad, and perhaps she should go to a doctor. incest thoughts arent good at all. and try to distance yourself from her slightly...change sleeping agrangements sorry bout your mother. and good luck.

You should tell your father and have a family meeting to talk about the issue.
