I'm a 17 year old male and my brother is 19.

I don't even know where to start..I've always felt some kind of attraction towards him, i started noticing when i was really young. He always made me sleep with him in one bed when i was 13, that's when i started noticing that i like guys, my brother found out that i'm gay when i accidentally left gay pornography on my computer, it was extremely embarrassing but he said he was also into guys. So we started sleeping in the same bed all the time. My mom notcied shortly after and we stopped it. She thought nothing of it. Everything was normal for a long time but then i started getting jealous whenever he was with girls or didn't pay attention to me. I told him about it when we were preparing to go to bed and he made me give him a blowjob in our bathroom. I still remember how he tastes and how much i loved it. I never felt the same way towards anyone. I tried dating guys and girls and even guys who looked like or acted like my brother but nothing was ever the same. I just wanted him to destroy me. When he went to college he moved to another town and started visiting us a few times in a month. When he visited and i was the only one home we had sex. Right now he is living with us all the time because of corona and i don't know what to do, i know that it's wrong but i just can't control myself. I've tried telling him to stop because it's not normal but he doesn't want to stop, i'm scared that we will get caught some day and i will get kicked out. Please, please give me advice, i don't know what to do.
