The most extraordinary changes have occurred in my marriage in the last few months.

It all began on Christmas morning, when I received a new motorcycle as a present from my sweet wife, Beth. I had wanted a motorcycle my whole life, but when we’d discussed it in November, she’d told me we couldn’t afford it this year. So, needless to say, I was thrilled with the gift, and thanked her over and over. When I asked her how we’d be able to pay it off, she smiled and told me not to worry about it. Since Beth handles the finances for our family, I didn’t feel the need to pursue it further.

Beth has always been a beautiful woman, and at 37 she still looks so young that she sometimes gets carded when we go to bars. She is five feet four, with short brown hair. Her breasts are perky B-cups, and her slim figure makes it hard to believe that she is the mother of two.

My sex life with Beth has always been good, but never terribly kinky. I got her to try anal sex a few times, and occasionally I would spank her lightly during sex, but for the most part she preferred keeping our bedroom activities fairly tame.

One afternoon in January Beth told me that the bank where she works was conducting some sort of pre-tax-time audit, and that she would have to work one Saturday afternoon a month until May or June. This disappointed me, since we always try to do something as a family on Saturdays, but I figured work was work.

The following Saturday Beth left the house around one in the afternoon and didn’t get back home until almost midnight. She explained her lateness by saying that there was a lot more work than they’d expected, and indeed she looked totally exhausted.

The next time her working Saturday came around, she was again gone until midnight, and returned home very tired.

About a week after that I happened to run into Howard, Beth’s boss at the bank. We chatted a bit, and during the conversation I asked how the audit was coming. Howard’s eyes went wide with surprise, and he asked, “What audit?” It only took a few more minutes of conversation to make me realize that Beth had been lying to me.

I felt crushed and confused, but I decided that I should wait until her next working Saturday to find out what was going on. I managed to act nonchalant in the meanwhile, but I worried a lot. I could only hope there was some reasonable explanation for her deceit.

When the day finally came, I waited until Beth left the house, then rushed out and got on my motorcycle to follow her. I was careful to follow her car at a distance, so she wouldn’t see me.

As I had suspected, it soon became obvious that Beth was not going to the bank at all. She drove downtown, and finally pulled into the parking lot of a motorcycle dealership. I rode on past, and then turned around and parked my bike at a restaurant next door. I wondered if this had been the place where she’d bought the bike, and I felt a little better, thinking that maybe she was doing some clerical or financial work for them to help pay it off, which she didn’t want me to know about.

There was a sign on the door of the dealership saying that they closed at noon on Saturday, and indeed the place looked abandoned. I peered into the window, but there was nothing to see except the darkened office area and a few display bikes. There was no sign of Beth. I considered knocking on the door, but then decided to walk around back instead.

In back of the building there was a garage for motorcycle repairs and tune-ups. It was shut up also, but as I neared one wall I began to hear voices. There were no windows, but eventually I found a series of grated ventilation holes that ran along the back wall a few inches from the ground. I knelt down on the gravel, peered into one of them and got the shock of my life.

Beth, my beautiful, demure wife, was standing casually in the middle of the garage, completely naked. Two men sat on a couch in front of her, both of them running their eyes avidly over her unclothed body.

“So tell my friend Rick, who you are,” one of the men said.

“Yes, Master,” Beth answered.

Master? I thought. What the fuck!

“I am Todd’s slave,” my wife went on. “I am his property. I will do anything he instructs me to do. I will be whatever he commands me to be. I will fuck whoever he commands me to fuck.” Beth said this as if she had memorized it, but I could see that her nipples were hard. I couldn’t believe it — she was excited!

“Wow!” Rick said. “That is something!”

“So are you ready to play?” the first guy — evidently Todd — asked.

“Sure,” Rick replied.

My first instinct was to do something to stop this, but my surprise and fascination got the better of me. Beth had never shown an interest in anything like this before. I could hardly believe that this was truly my wife.

At Todd’s instruction, Beth fell to her hands and knees and crawled over to the men. She then opened their pants, and began giving Todd a blowjob while stroking Rick’s cock with her hand. A wave of jealousy struck me as I realized that it had been a long time since Beth had blown me.

Soon her mouth moved from Todd’s penis to Rick’s, and then she was alternating between the two. As her head bobbed up and down I had a terrific view of her tight ass waving in the air. Beth always gave a great blowjob, whenever she could be talked into it, so I wasn’t surprised that before long Rick appeared ready to come. Recognizing that he was on the edge, Beth stayed on his dick and quickened the pace of her sucking. I heard Rick groan loudly, and I knew he was shooting a ton of come down my wife’s throat.

As Rick relaxed, Beth focused her attention on Todd, and within a few minutes he too was spurting his come into my wife’s mouth. I found myself wondering if giving blowjobs was all she had been doing during her mysterious Saturdays. Part of me hoped it was, but another part was hoping to see more.

The latter part won.

For the next three hours I watched as Todd and Rick took turns fucking my wife. They took her every way imaginable — missionary, doggie-style, standing up, bending down, and with her on top of them, facing forward or away. Sometimes one of them fucked her while she took the other in her mouth. Todd liked to pull out of her mouth when she sucked him to climax, and come on her face or in her hair. Beth took it all without a word of complaint.

On one level, of course, I was appalled by what I was seeing, but I couldn’t ignore the raging hard-on that I’d gotten from watching my wife acting like the perfect sex slave — a side of her I’d never known before.

By five o’clock both Todd and Rick had come at least six times each. At that point Rick said he had to be heading home. After he left, Todd told Beth to take a break while he got things ready.

As my wife rested on the couch, I watched Todd setting up lights and things in the garage. I received yet another shock as he rolled out a video camera. He also brought out a large gym horse, and told Beth to lean over it. She did as he instructed, and he tied her wrists and ankles to the legs of the apparatus. In this position she looked completely vulnerable to anything anyone might want to do to her.

Todd then produced a thin black blindfold and tied it across Beth’s eyes. Next he took some sort of lubricant and squirted some on her ass, then rubbed it around her asshole. I could guess what that meant, although Beth hadn’t agreed to have anal sex with me for over two years.

He was still playing with her ass when another man showed up, a skinny guy who Todd called Ed. He didn’t seem surprised to see my bound and naked wife, and he immediately began to undress.

Todd picked up the camera and began recording. He started by interviewing my blindfolded wife. “Are you ready to get your ass fucked silly, girl?” he asked her.

“Yes, Master.” Beth answered. “Whatever makes you happy, Master.”

This whole thing seemed crazy to me, but my dick was achingly hard. Todd brought the camera around as Ed took his position behind Beth. She gasped with unmistakable pleasure, then began to whimper as Ed guided his dick into her ass. He started fucking her slowly, taking measured, even strokes, but before long he was hammering away like mad, while Beth emitted loud yelps of delight.

While Ed was fucking her, two more men arrived. They greeted Todd and then sat on the couch, presumably to wait their turn.

odd moved the camera around to get good close-ups of both Beth’s ass and her face. When he was ready to come, Ed pulled out of her ass and moved around in front of her, thrusting his cock at her mouth. She took it willingly and began to suck it hard, moaning rhythmically around the hard flesh. Todd moved the camera in close and caught a great come shot as Ed pulled out and squirted his thick jism all over Beth’s cheeks and lips.

Todd yelled, “Next!” and one of the men on the couch moved up behind my wife, unzipped his pants and guided his cock into her just-fucked hole. Meanwhile more men kept showing up, until there were at least a dozen of them. Each one of them took their turn fucking Beth’s ass, and she sucked and licked every one of their dicks clean afterwards. After that the men got dressed, thanked Todd for his hospitality and left.

Todd untied Beth and removed the blindfold, then told her he would see her next month.

I managed to get home before my wife, and when she came in she was surprised to find me waiting up. She had cleaned herself up well, but she still looked flushed and well used. At that point I confronted her with what I had seen.

After her initial shock, Beth broke down and confessed everything. She explained that the Saturdays had begun as a way to pay off the bike, but that she loved them and was now addicted to being a sex slave. She was incredibly relieved when I told her that I was not angry, and didn’t want a divorce. After some discussion I agreed to let her continue with her monthly Saturday orgies, provided I could be one of the men involved.

Beth was so happy with this development that she immediately got down on her knees and gave me a fabulous blowjob. As I said at the beginning, things have definitely changed in my marriage — for the better!
