It was the summer of 1986. My wife, Linda, and I moved to the Southern California desert shortly after getting married. I was 25 and she was 31. We did so to get a new start at my new job, and she eventually found work as well. Our sex life was vibrant and we discussed taking it to the next level by inviting others into the bedroom. We both agreed, but with ground rules. It was for physical pleasure only. No secret dates and no falling for someone. We loved each other and were mature enough to be honest and trust each other.

We made friends easily and began inviting people to the house where they could enjoy our backyard swimming pool. The people we met were our age and seemed to be like-minded. On one particular afternoon, the BBQ was cooking and the alcohol was flowing. We must have had about 5 couples and six or so singles, male and female. Everyone wore a bathing suit and I must say, it was arousing to see so much bare skin in our backyard. Linda was feeling the effects of the alcohol so she told me she was going to change into her new bathing suit. I thought she looked fine but off she went into the house.

A few minutes elapsed before Linda returned. The bathing suit was a two-toned bikini. The top was white and the bottom was blue. She was very shapely and as she slowly walked through the group at the party, people noticed. She came up to me and asked me how she looked. I said she looked fabulous. Then she told me to watch her jump into the pool. She jumped in and her head popped up. She looked at me and smiled seductively. I smiled back but I couldn't figure out why she smiled at me like that.

Linda swam to the shallow end and slowly walked up the stairs and out of the pool. I noticed the people at that end were looking at her, both the men and ladies. Linda turned to walk toward me and I initially thought she lost her bikini top. I could clearly see her areolas and nipples. She smiled at me again and walked past me toward the spa. As she walked past me I saw that her bikini top had become sheer and it was as if she wore nothing on top.

Linda entered the spa and joined a couple and a few others, but it didn't take long for the spa to be busy, mostly by guys. I noticed that Linda sat in the spa and the water stayed at her shoulders. Every few minutes she sat up and her breasts were exposed above the water line. She seemed to enjoy the attention and frankly, so did I. One of the single men, Larry, sat next to her and began a conversation. I stood at the BBQ and watched as Larry appeared to be hitting on Linda. I didn't mind it one bit. The more they talked they seemed to sit closer to each other and both were smiling and speaking closely, almost in low tones so no one else could hear.

The afternoon wore on and Linda and Larry left the spa and got into the pool. Linda's bikini top was still sheer and she loved showing what she had. As the sun began to set the guests started to leave. A few drunks fell asleep on the chaise loungers and Linda and Larry continued their conversation along the pool's edge, their feet dangling in the water. Linda occasionally reached into the water to scoop a few handfuls of water to pour over her chest. This, of course, caused the bikini top to turn sheer again and Larry looked every time, as did I. I was cleaning around the pool area and I asked Linda to help me bring some plastic dishes into kitchen. She excused herself from Larry and helped me.

Once in the kitchen, I asked Linda if she was enjoying Larry's company. She said she was and I then asked if she'd be willing to seduce him so I could watch. She thought for a moment and happily agreed. I told her I'd be in the bedroom watching through the window. Linda left the kitchen with a new purpose.

I walked to the bedroom in the back of the house and made sure there were no lights illuminated which would cause my silhouette to be visible. I pulled a chair to the sliding glass door and opened the blinds. I had a clear view of the pool including Larry and Linda. The sun had set and the pool light and backyard lights provided sufficient lighting for me to see. When Linda returned to the pool from the kitchen, she sat in a chaise lounger next to where Larry was in the pool. They spoke for a few minutes and Larry got up from the pool's edge and sat on the edge of the chaise lounger Linda was occupying. As they spoke, Larry placed his hand on Linda's leg. Linda did not do anything to dissuade him.

A few minutes later, he moved his hand to the inside of Linda's knee. Linda spread her legs ever so slightly. Larry immediately moved closer to Linda and moved his hand to her inner thigh. At that Linda spread her legs wider, put her hand behind Larry's head and pulled him into her. They kissed deeply as Larry's hand found its target, Linda's hot spot. By now I was naked and stroking my hardening cock. They kissed for a while as Larry made small circles on Linda's clit. Her hips began to move and she began stroking his cock through his swim trunks.

Linda sat up on the lounger and removed her bikini top then her bottom. Larry stood and removed his trunks. His cock was stiff and standing upright. Linda directed Larry to lay on the lounger and he did so without question. Linda knelt down and began to orally pleasure Larry. Watching her head bob up and down and lick his shaft made me stroke my hardness a bit faster. Linda sucked Larry for several minutes before standing up and straddling Larry's hips. She gripped Larry's cock and guided it into her wet pussy as she slowly lowered herself onto him. Larry guided Linda's hips as she began to grind on him. Her nipples became hard and I heard soft moans from them both. The drunks were still passed out on the loungers, oblivious as to what was going on just a few feet from them.

Larry reached up and pinched Linda's nipples which caused her to moan louder and move her hips faster. Her hands came up and covered Larry's hands until he moved his hands to allow Linda to continue pinching her nipples. Linda's breathing was fast and her moans became louder.

"Fuck me with your hard cock," Linda said between breaths.

Larry's thrusts became harder and appeared to go deeper.

Linda cried out, "Yes! Fuck my pussy! Make me cum!"

Linda was pulling on her nipples as she rode Larry with determination. Larry began to moan and thrust into Linda, cumming inside of her.

Linda moaned, "I'm cumming!" At that she rode Larry with abandon and her brow furrowed as her orgasm washed over her.

Meanwhile, I was also releasing my orgasm at the sight of Linda enjoying another man. I was so turned on, I licked the semen off my fingers.

Linda collapsed onto Larry's chest and they both held each other until their breathing subsided. They spent a few moments giggling and they both obviously had a good time. Linda got off of Larry and they both put their bathing suits back on. Larry left through the side gate and Linda came into the bedroom, clearly excited.

"Did you see that?" she exclaimed. "My goodness, I hope you had as much fun as I did!"

Linda looked at the chair in which I sat and noticed my semen on the front of the seat and on the floor.

"Mmm, obviously you did," she cooed. "Would you mind if we did this again, if you don't mind watching? Knowing you were watching was the real turn on for me."

I thought for a moment and said, "I really liked watching you with another guy. If you want to do it again, I'm ok with it."

Linda smiled broadly and gave me a hug. "I love you so much."

"I love you, too."

At that we kissed and went to bed for a raucous round of lovemaking.
