To be fair, personally I got a good but unusual result from AFF about 10yrs ago. I say unusual result because I had only been on the site a week when I was approached by this couple in my city. The wife informed me that her husband enjoyed watching her getting ploughed, and they could both come to my place if i was game. I had never been in this unique situation before, so I thought about it for a minute and decided to go for it, since I was single and free.
They came to my place 2 days after the initial contact (on a Saturday afternoon). The initial 5mins was still a bit awkward for me, but the hubby put me at ease and encouraged me to sit on the couch next to his wife. She and I started to make out while he pretended to watch tv. She then suggested that we take it to the bedroom and all 3 of us went up. The husband sat on the stool by the dressing table while the wife and i undressed each other and got to work. He just sat there silently and watched. I kept expecting him to jump up in rage and stab or punch me, but he never did. After our session, the guy and his wife stayed for some minutes of small talk and left.
They came again for about 3 sessions before the husband suggested that his wife could come on her own from then onwards, as he was satisfied that she would be safe with me. He would be happy to receive session reports when she got home.
I saw her 2 times by herself before I changed my phone number since I had entered a LTR. I then terminated my AFF account soon after.
So AFF to me delivered the goods.
