I come to my brother's room for my weekly feet massage. He is getting better and better so this time I am going to enjoy myself even more. We start chatting and it turns out we have both had fantasies about each other. I even roleplay brother and sister sex scenes with my boyfriend. We find these fantasies super hot, but we know that it's inappropriate to persue it. Talking about it will do no harm, right? I am engaged in the conversation and I don't notice that my brother is staring at my pussy. What is he doing? We agreed that we wouldn't do anything wrong. Though, I can look at my brother like that! His dick has gotten all hard from massaging my feet and peeping at my pussy. I need to help him! We start masturbating together and we enjoy it. I wouldn't have thought that mutual masturbation with my brother could feel so good! After a moment he asks me if kissing is not allowed either. Well, I guess kissing is not sex. I get closer and start french kissing him whiloe he strokes his cock. Hard to admit, but I get super horny too. Kissing my brother really get me all worked up. I think to myself - what do I have to lose? I take his cock into my mouth and start sucking. When he is almost done, I switch to my feet and finish him off with a footjob. He covers my feet in his cum.
