I've been playing Betty off and on for several months. Betty's my neighbor. She's got just about the hottest body I've seen in this town.

About 5'7", full 36" breasts, unrealisticly small waist, and the dandiest pert, well-rounded buns you've ever seen. I've never minded her more average facial features, because, basically, I was never looking at them. From the start, it was Betty who seduced me.

I never asked why. Her husband, Adam, is a big fit fellow like myself - probably better looking than me and definitely a better dresser. Adam certainly seemed like somebody who should satisfy her.

Plus, I always liked Adam, and there was always some guilt and remorse after I'd played Betty about how I was betraying Adam. Recently, I was over at Betty's on my day off. I knew that Adam normally worked that day - I also knew that it was the time of the month when Betty was at her hottest.

We were in the bedroom, totally naked as usual. What was unusual was that we were using the missionary postion. I don't mind that, but Betty prefers positions where either or both of us can access her personal placeoris. Suddenly, I sensed someone behind me.

My body stopped it's rhythmic motion and stiffened up. Betty said "Relax, it's OK, it's just Adam." Just Adam! I thought, He'll kill me! "Adam wanted to join us.

" she continued. Over my shoulder I could see that Adam was naked - I guess he'd been in the closet watching the whole time. A lot became clear over the next hour or so. Adam got down behind me, rubbing his hard thingy between my bun, while I continued to play Betty.

I guess I still considered myself a bisexual, even though I hadn't touched a man in years, so this didn't instantly repulse me. Betty seemed to enjoy the added pressure pushing into her and the overall eroticism of the situation. After several minutes of this sort of play, Adam got off long enough to administer lubrication to his thingy and my soft place.

The initial entry was painful, I even began to soften up a bit inside Betty.

But after those first few minutes with Adam pushing deep inside, it became quite arousing and I was harder than ever. As he picked up the pace and power of his thrusts, I did the same with mine. Betty was moaning wildly. She was the first to come. She more or less exploded under me.

She bucked and writhed trying to get more of my length as I came. The spasms in her softness were more than I could take.

I started to cum, the most massive orgasm of my like. As I came, my soft place tighten up and this triggered Adam. Before I was done shooting, I could feel him tighten up, push deep and pulse his load inside me. There was some pillow-talk afterwards.

It turns out that Adam prefers sex with men, and they have a more or less open relationship that allows them to pursue relatively safe sex on the side. He had actually watched me play Betty a couple times before, and they'd cooked up this surprise because he'd become interested. We have three-ways frequently these days.

Sometimes, if Betty's not in the mood, Adam just plays me.

It's a great situation and I hope it never changeslt
