Phil's obsession was to show his wife off naked to other men and maybe watch them fuck her in front of him. He fantasised about it constantly. Theresa, his wife, refused to play ball although he'd only dared broach the subject indirectly. The only time he mentioned couples who did threesomes – there was a story in the paper – she said the very idea was disgusting. When instant cameras became popular, he bought one, suggesting jokingly (she thought) that he could photograph her nude. She responded with a single word: never. It wasn't that she was prudish with him. When she was in the mood for sex, she'd tantalise him with her cleavage or a show of leg. They had regular sex. It's just that she thought it should be private. Had she known what he dared not utter, she'd have killed him on the spot. He told me all this at work. He had a photo of her in his wallet – just a headshot – and she looked not bad. Nothing special but I think ordinary women are often sexier than models. I asked to see more photos and he brought some in. Mostly she was fully clothed but there were a couple of her in shorts and one in a swimsuit. Phil knew I was a wanker because we'd talked about it together. I told him that Theresa gave me the urge which was true. He was intrigued when I said I could get off as well on clothed women as on nudes. When I asked to borrow the photos, he wouldn't, saying he wanted to be there. I didn't mind because I get a kick out of being watched though it's only happened before with tarts I paid. We fixed for him to come that evening to my flat where I live alone. I did wonder if I could go through with it, wanking in front of another guy. But it went off okay. We had a couple of beers and he spread the photos on the bed while I took my clothes off, not at all embarrassed like I thought I might be. I lay on the bed and played with myself while Phil talked about stuff he and Theresa did together and how she loved him to play with her clitty. I don't know how much of it was true but it got me nice and hard. I picked out a photo I liked of her sitting in a dress with her legs crossed and looking at the camera and told him to put the rest to one side. It was as if she were looking straight at me, watching as I began wanking. I stretched it out a bit because it felt good but eventually I couldn't hold it back and cummed a load. We had more beer and I did it a few more times. Phil wouldn't be persuaded to join in but I didn't mind, in fact I preferred it that way. As I said, I like an audience. He's introduced me to Theresa since and I get the impression she doesn't like me all that much although she's always polite. That doesn't bother me at all. Phil has now given me some photos of her and it tickles me that she has no idea of the secret tributes I pay her.
