Half-brother becomes jealous when she goes out with other men

Me and my brother-in-fuck from when we live together. It is not a formal relationship, fuck occasionally. Basically when our parents are gone. But every time I go out with another man, this is a problem for him. Is always jealous. But there is nothing I can do, I will not stop to have fun with other men. Then, to calm his jealousy, I always dirty things. Today, in the bathroom, while I dressed, I made him a blowjob. I also got a saw in spain with my boobs. I had enough time before the appointment, and I went in the room with him. We fucked for an hour, and I also felt so whore that I asked him to fuck me in the ass.
