I watched my sister’s face as I licked her pussy. She was grinning like a mad man, and I knew it wasn’t because I was good at this - it was because she could see our cousin impaling me on his cock as well, and she was enjoying my face every time he hit deep into me.
I never even really liked giving blowjobs until I saw my brother’s cock. Watching him jerking off that time, I suddenly felt that need that other girls have for a cock in their mouth. Now, I get to experience it regularly, and with my brother, too.
