My brother and I came to the Halloween party. I was wearing an amazing Wonder Woman costume. I knew it was my brother's favorite character. Of course, we hung out in the kitchen separately from everyone, because I wanted to fuck him. We laughed innocently and flirted and I decided to act. I showed him my chest and knelt down to suck his delicious dick. After a great suction, I asked to fuck me from behind. But when I was close to orgasm - a girl from a party came into the kitchen and we had to continue in the room upstairs.
