My wife is a young beautyfull blond white woman, but I think she is on the way to cheat me, because i can t not fullfill her requirements. That is sink in me, as I found accidental her pc and on this day is was not close. I saw that she wrote with black guys on a adult interracial website and some of this chats was open and she offer herself to this black guys. Some weeks later I found her mobile phone and it was not barred in this moment. I saw that she had a intensiv chat with a black bull from the near. In this chat I could read that they have secret dates but I beliefe that they drink only coffee and talk together. I saw pics from this black bull.
