She is fascinated by the size of the cock of his half-brother

I Knew that my brother was very sexy, but I didn’t know that his cock was so big. This makes it much better. This morning I saw his cock for the case, an accident very lucky. I went in the bathroom and there he was naked. I closed the door quickly, I wanted to be alone with him. I have not lost time and I grabbed his cock, I masturbated him and he had an erection bigger. I took a couple of slaps with his penis and then gave him a blowjob. My half-brother he lost control and fucked me from behind. Then we went in the room to be more comfortable. We have done things very dirty and I also did anal sex with him. My half-brother is more useful than I thought.
