I'd been on a chat site sharing erotic thoughts with some unknown people and had struck up a conversation with a guy who seemed to share my fetishes, fantasies and kinks. We chatted one on one through personal messaging. I told him about my secret dressing up, in my wife's underwear and a few times in over clothes too. I really opened up, he was very receptive, and I told him of my love of humiliation, the idea of jealousy as a sexual enhancement and how I imagined my wife with other men, stripped and gang banged. I made it clear that it would have to be semi consenting - I hate violence and would never want anyone scared - rape is a dreadful thing, but rape fantasy can be different. Anyway, he asked for my yahoo address so I gave it to him and we connected. He didn't have a web cam, but wanted to see mine work. I was reluctant, I'm not gay, but must admit that the conversation had turned me on and I was liking it. He was going to go so I agreed to put the camera on in a conferencing room in yahoo. You probably get the feeling that he was obviously manipulative and after I realised it, but at the time I was enjoying the control he was using on me, to be honest, it felt exciting. He asked if it was ok to invite some others he knew and I said why not, would be interesting to have a big conversation on line. I got several invite requests and ended up with about 8 connections in the conference. I put on my camera but kept it so you couldn't see my face, I'm very well aware of the risks of on line contact with total strangers! We chatted away, exclusively about sex as a bunch of guys on line always do but he kept turning the conversation around to me and my fetishes. He was very clever, with hindsight, in getting me to open up and also told the others point blank that I would like to see my wife with other men, preferably a lot of them at once. I realised gradually that they were not being particularly nice to be and were almost bullying, jeering and treating me like a pervert and, undeniably, it was having an effect on me, my cock was almost constantly hard and I realised was pretty much copiuosly dripping pre cum. They were turning me on with their humiliating comments. He actually started to call me a sissy and a slut and suggested I wanted to do things with men. Finally he said that he thought I wanted to show them all my 'big clitty' as he called it and said I should undress on camera for them, as I was not man enough to deserve to wear 'man clothes'. I was so turned on that I really did want to undress, to be seen by these invisible strangers! He told me to take off my shirt, to do it on cam so they could watch. He didnt ask, he told me to do it. I loved the feeling of helplessness, even though I was far from helpless, he had complete control of me. I took off the shirt and was met by comments like 'ooh sissy boy' and 'what a poof'. Next went my trousers, I wasnt wearing socks. They pretty much went wild when they saw my grey briefs and the dark wet patch and bulge of my erection! In particular he commented saying I was a pussy and a wanker and clearly a homosexual who wanted to suck cock and see my wife sucking cocks and eating cum. All this did was to make it harder to hide my erection and the wet glistening knob end popped out of the briefs much to their delight. He instructed me to lose the underpants and I dutifully stepped out of them, dripping pre cum all over the place. I had to go and get some tissues and when I came back they were still all waiting and watching. Ok, he said, now I want you to go and get some of your wifes underwear and show us. To be continued.
