My brother wants me to have a threesome with his wife. What about me?

So this is my story.<br><br>I am not sure if it makes me a bad person, but I am jealous. I have a brother who is older than me and he is married. He loves his wife very much, and I can tell.<br><br>What angers me is that he asked me to have a threesome with them. I have never had sex before, and so it would be my first time. <br><br>I said yes, because I know my brother can be very persuasive. He can make people say yes to him even if they don't want to.<br><br>So I said yes, and then after sex, we stayed in bed for a while. But he cuddled his wife the whole time. I know that his wife is his priority and is going to always be. I can't help but wonder what my place in his life is. He seemed to ignore me except for when we were having sex. He didn't cuddle me or put his arms around me. I admit I was a little hurt by it.<br><br>I am not sure if I should tell him about it, or if it will anger him. He has his arms around his wife right now while we are all on the couch. I know I am his sister, but I also feel like I am the person he just had sex with. He talks about how his wife is sexy, and I am starting to feel bad about myself.<br><br>I don't know what to do. I want my brothers hugs and cuddles, but I don't want to make him mad at me. I also don't want to make his wife mad at me.
