wife going through with it

Im so nervous yet excited. my wife is going to have sex with another man today. we are going to leave to pick him up around 2 pm and we will get him back here at about 8 pm. he is a friend of my wife's that she has known for about 3 years. they are good friends and he has visited us once before but nothing happened as we were not into that back then.
I first brought up the whole "her with other men" scenario years ago. I was 20 and she was 18. I told her it turned me on for her to make-out with other guys. I told her she deserved it because she is so beautiful. she accepted and had one make-out experience with a guy in her mom's hot tub. he wanted to have sex but she denied him. She has only had sex with me as i had taken her virginity. when she told me about the experience she was kind of scared to, but she managed to leave me a note letting me know. When i read it i confronted her and told her i was happy for her. she then told me about the whole experience. he was 28 and they got hot and heavy in the hot tub after everyone had left and they had gotten takes. since then it has been 5 years and she has not done anything with a guy. about a year and a half ago i brought one night when we were takes that i would like her to fuck other guys while i join in or watch. she reacted badly stating that i did not love her. i told her that it was to the contrary, that i loved her so much that i wanted her to do this as she has not fucked another man. she said ok and every once in a while i would bring it up again. i finally mentioned her friend one night and she agreed. she called him and he said it would be fun. we then had unbelievable sex! she was so turned on. we got married and time went by and finally i brought it up again. she called him to see when he would be around and he was nearby! he is in the air power and visits his hometown a couple of times a year. he is visitng home for thanksgiving so he will be within a few hours of us. My wife was excited yet cautious, she has been with other women but she said this would be different. i agreed but told her i am ready for it so she is willing. One thing though. I asked her if we will have a threesome and she told me that she would be uncomfortable with both of us fucking her. she said it would be better if she fucked just him alone. I asked her if i coud watch and she said she would rather i didn't. i am used to this as i am not allowed to watch her with other women. yet this kind of shocked me and turned me on at the same time. I asked her if i would be allowed to listen at the door and she said it would be fine. my wife is a beautiful, petite women and i love the idea of her being fucked by another man.
the idea of her humiliating me by not letting me watch turns me on so much! i asked her if she would use the vibrating toy that she uses when we have sex to bring her to orgasm. she replied that she would not because the excitement of the sex with him would bring her to cum. he is 8 inches long and 2 and a half fingers thick, i am 6 inches long and two fingers thick. she said his big cock would probably make her cum. i was astounded at the way she was speaking to me! its like she knows what i desire from her verbally!
I don't know why these things turn me on so much but i am so aroused by all of it. my sweet petite wife will become a whore today! I am so lucky.
