It started like this.
"You make good money, but it all seems to go to paying expenses. I want to start a business so I can have some mad money to play with."
"What did you have in mind?"
"I want to have a happy ending massage business right here in our home."
"Absolutely not! I'm not going to have some strange guy alone with you. Anything could happen."
"That's why we'll schedule our appointments on times when you can be home. You'll be sitting in the next room watching everything on hidden cams. If something should go wrong, you can be my knight in shining armor and come in and rescue me. Besides, you have been telling me that you fantasize about me being with another guy. This could be your fantasy come true!"
To emphasize her point, she sat down next to me on the couch and started to rub my already expanding member. She smiled when she felt how hard I was, because she knew she was going to get her way.
The hour-long session started in our back yard hot tub. She served her customer a drink. We have a well-stocked bar, and the two stripped naked and got in the hot tub. Katie, my wife, is a beautiful woman. She has a great body with an all-over tan from being nude outdoors a lot, long blonde hair, and blue eyes. When she got in the tub with her customer, I could see that he was intensely attracted to here. They sipped on their drinks and chatted for a while to break the ice. Then it was time for the massage.
They dried off went into the bedroom where Katie had a massage table set up. He lay face down at first. I had cameras set about the room from different sides and different angles and I could see as he climbed on that he was already partially erect. Katie's fingers were using long, soft strokes across his back, down over his backside and down his legs. He spread his legs, so she could stroke his inner thighs. When her fingers lightly stroked across his balls, he let out a groan that was so loud I could hear it from the next room. She continued up and down, making sure to feather stroke his balls each time. He was going crazy, and so was I. I couldn't help but to stroke myself while I watched. I couldn't believe how turned on I was getting! He reached around her with his arm and started caressing her body up and down. When he put his hand on her butt, I thought she would stop him, but she didn't. He worked his hand down between her legs and started to caress there. I was wondering if she was wet, but I was guessing that she probably was! I couldn't believe what I was seeing! Then she asked him to turn around.
I was not surprised that he was fully erect. She went right to it and started to stroke it while he continued to fondle her gently. I knew how good she was at that, so I knew he wasn't going to last long. I was so electrified by what I was seeing that I didn't think I was going to last long either! Then came his panting, squirting, moaning orgasm. It was so intense that he was breathing heavily afterwards and motionless. When he finally recovered, Katie went to get him some water while he put on his clothes. He gave her a huge tip, a big hug, and left a very satisfied customer.
After he left, I came into the room and Katie had undressed again. She told me, "Now it's your turn to claim me back, and it's my turn to cum!"
I kissed her and ran my hand down between her legs. I was right, she was soaking wet! I lay her down on our bed and went down on her. She was so turned on that she came almost instantly. We were both filled with passion as we made love for the next of the evening.

Afterwards, as we held each other sweaty and exhausted, I asked her, "So how far are you going to take this?"
She gave me a huge grin and said, "You'll just have to wait and find out."
After a few weeks, her business was already booming. She had some regular customers, and she was still meeting new ones. During this time, our love life had never been better. We were making love every night like newlyweds.
It was a Saturday morning when Paul came over. Paul was a regular, with a nice fit body. The massage was going as usual. She had got to the happy ending part and was gently stroking it with her hands, but this time with no lotion. Then Katie bent over and took it in her mouth. Yes, this had always been one of my fantasies and now it was happening! Paul groaned loudly as Katie's tongue made long strokes up and down his shaft while she lightly stroked his balls with her fingers. He had his hand on her dangling breast and was gently squeezing her hard nipple. When she knew he was ready to finish, she rapidly flicked the tip with her tongue while she stroked with her hand. When he started to spurt, she closed her mouth around the head and continued to stroke with her hand to milk out every last drop.
When Paul left, I rushed into the room aching to fuck her. She smiled and lay down on the bed for me and I immediately thrust into her. After some very passionate, hard, quick thrusts, I slowed my pace and kissed her. I could smell Paul's seed on her breath and taste it in her mouth. To my surprise, instead of being repulsed, it was like an aphrodisiac! My thrusts became fast and hard again and soon I was gushing inside her.
The blow jobs became a regular thing with her repeat customers. She was taking all different lengths and girths into her mouth, and she seemed to enjoy every one of them. The money was pouring in, as the tips had become much larger, and we were both happy with the situation. But once again, I wondered just how far this would go. When I asked her, she would just grin and tell me, "Wait and see."
When Paul came back, I was a bit nervous. Katie had told me that she had become very attracted to Paul. The hot tub ice breaker had included kissing and fondling this time. When she got to the oral part of the massage, she stopped after a while, lightly stroked his wet member with her hand, and told him to get up. She led him to the bed, bent over and put her hands on it, and put one foot up on it. She had positioned herself so that the cam had a clear view of her pussy. So, I had a perfect view when Paul slowly eased into her. I couldn't believe it! This was actually my wildest fantasy come true! Paul was fucking my beautiful wife!
I could look at one cam and see his shaft thrusting in and out of her, and I could look at another cam and see the look of ecstasy on Katie's face. Open mouthed and panting, Katie was enjoying this as much as I was! The climax of Paul groaning and pumping his seed into her was incredible.
Afterwards, when I rushed into the room, Katie asked me If I wanted her to wash up first. I told her no, and slid my throbbing cock into another man's cum.
I couldn't wait for her next regular customer!
Look for Part 2
