SPD how it happened

Ok, Those were the details of my SPD 3some. Now for the behind the scenes info. My bf was tending bar when he met this girl. I tell you he can charm the panties off any woman and she will do anything for him, but this girl had her own agenda. After my bf charmed her and got her to agree to a 3some with us, he asked her what her darkest fantasy was. She played coy at first and then claimed no one would do her fantasy. He assured her that we have done it all and would perform anything she wanted. She hesitated at first and then said "ok I want to be raped". 
 She told him that her sex life was terrible and that she wanted to be completely taken, used and violated by a woman and man. She told him that she always  wanted this and she was ready to do it. He told her" baby have you found the right couple"  :-) She agreed to meet him after his shift and go to our house.
 When she met him after work, she told him that she had some rules for us to agree to. She did not want to know our names. She did not want our phone numbers or address. She had to leave our house by 7am. When we get to your house, no introductions to your gf. I want you to start right away when we walk into the house. This was the only time that we would see her, so do our worst. Do not try to find or contact her ever. My bf agreed, he called me to inform me of her rules and to get ready.
 He asked her why the rules? She said "she was married to an older, rich, crazy man". She told my bf that he was out of State all night with his friends and this would probably be her only chance to do this. My Bf told her he understood but he wanted to video tape her request for this type of play. I left the video camera in our entry way. He recorded her saying she was sober and not on drugs and that she  requested to have rape fantasy role-play with us. He had her state that she didn't want us to stop, no matter what we did to her. He had her state that she refused to use a safe word and even if she screamed  for us to stop, we were to keep going. We hoped that would legally be enough if she turned out to be crazy. 
 You read what we did to her and true to her word, we haven't heard from her to date..
