It was a big surprise when I saw my dominant sister with my wife's wedding dress the day of my wedding! Not only did she claim that my cock only belonged to her, but she made me lick her pussy and boobs as a sign of repentance... But she wanted more... she wanted to fuck me on my wedding day. So when my wife returned to the room and catch us, my sister far from cutting herself off, decided to continue riding my cock in front of her, even consoling her when my wife burst into tears "don't worry, it's all in the family"; "it's just that your husband can't stop fucking his sister's pussy" After continuing to riding me, she demanded that I fill her pussy with my cum... and looking into my eyes she said: From now on this is the only place where you will be able to cum... I don't know what I'll do with my sister... but she's partly right, I can't stop fucking her pussy
