My brother raped me

I just turned 18. it happened last week he came to my room on a Monday night while I was watching YouTube and he layed next to me. We both watched those mucbang videos for a few minutes. Suddenly he stands up and walk to the door and he closed it. I didn't think much of it and continued watching YouTube. He then turned off the light saying it's looks better watching YouTube in dark so I agreed, but that changed everything. In the dark he suddenly jumped on top of me and pushed my head down. I thought he was tissing so I tried to get back up but he was so strong, he was 22. And quickly something I thought was tissing turned into something else. He ripped my clothes and pulled down my underwear while pinning me down. At that movement I started crying from pain and he put his tongue in my vagina and he started doing things with his tongue. And he bite and sucked my private area. I didn't know what to do. And then he pulled his pants and underwear down and he, he put his disgusting penis in me.it hurt so bad and I told no no, I begged him to stop but he didn't. It went on for 17-20 something minutes until that fucking asshole left his DNA in me. After he came in me he just got up and left the room while I was laying there, unclothed, all the parts of my body I kept private was now seen and enjoyed by him. 2 minutes later he came back with he's phone and took videos and pictures of my naked body. And threatened me that if I ever tell anyone about him raping me, he would send this pictures to everyone in my school group. So I shut my mouth amd listened to him. That night I felt great pain in my stomach and my vagina but I endured it. But it didn't end there. He came back the next day to rape me again. I begged and begged him to stop but he didn't. It went on for 4 days until I finally gave in. He uses me now every chance he gets. I too IAM now somewhat enjoying this. Or so I think.
