Help! My Cousin sed-ced Me, Now We Have S*x All the Time

A girl feeling guilty after her cousin sed-ced her into having s*x has cried out for help as she can no longer stop the act.
A woman has cried out for help after she was sed-ced by the cousin and now they can’t stop it. Read story below:
He tries to have s*x with me. He humps me hærd and sometimes he is n*ked while I have clothes on. I didn’t want to do it at first but now we do it all the time.
Most of the times I will be sitting on the computer or sleeping or whatever and he gets me to come to his room before our parents get home.
It’s not rape because I like it. Most of the times, it isn’t really s*x, just humping and masturbation.
He is my cousin and I’ve seen many similar stories on this forum recently. What should I do? Is this bad? How can I get over it?
