I come to my step-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 step-brother and step-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 step-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 step-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 step-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 step-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.
