I have always had this obsession for men looking up my wife's dress, I don't know where it started but it has stayed with me all my life. I have always insisted she has stockings on or bare legs and always white knickers, these show out more than other colours. Unfortunately you have to be more careful these days with mobile phones as you could wind up on YouTube I told her after some time I would like to be the voyeur, looking up her dress with someone else touching her, she seemed shocked she thought flashing was enough, I told her my obsession was getting stronger, in fact I would would walk around parks in the summer to find girls showing their knickers and wank off at home, I went on line to find many men had the same fetish as me,finding someone to take my place was difficult let alone who she would agree with. We spoke about my obsession and she said she was happy to go along with what I wanted, my wife has had a few relationships since we were married and I was happy to hear all the details. She told me that she had sex with somebody from work which she had told me about while wanking me off. We have an open. Relationship so we don't mind what the other does as long as we both hear the details, she said that on Fridays the office went for a drink, why don't you suggest a walk in the park, with the man you had sex with. I suggested a place where we would sit when she was flashing, I got there early and waited, they turned up and started kissing, I could see them and just expected to see her knickers, he held her and his hand went between her legs moved her knickers over and started to wank her. I didn't expect this she seemed to love it , fortunately I was out of sight and could start wanking as I watched, his fingers moved back and forth she was heaven, she rubbed him through his trousers and because where they were they made each other come. I wasn't far behind them. I met her back at home and immediately felt her knickers, she was very wet and she had come on his fingers, I want him to fuck you next time. She agreed, she took her knickers off and wanked me in to them telling me every movement they did. We would repeat this again but go further, let you know.
