It had been an unusually slow Wednesday at the office. I hung around a bit past lunch break before deciding to cut out a few hours early. Things had been pretty chilly between “the Mrs.” and me, recently. We would have a couple of hours before the kids got home from school, and I hoped that we would have some time to fool around.

As I pulled up to our humble townhouse, Rebecca was nowhere to be found. It seemed most likely that she had either left to run errands or do some shopping. I parked my car in the garage and closed the door. I made my way through the house and upstairs to the bedroom, cautious not to make a mess. If I wanted to continue with my quest for a romantic encounter, it would bode well for the house not to look like a disaster area when she returned home.

I had just walked into the bedroom and removed my shoes and shirt when I heard a car pull into the driveway. Looking through the window, I saw it was Rebecca, but another vehicle pulled in seconds later. A strange man, wearing a business suit, climbed out of the second car. I watched in shock as he approached Rebecca, cupped her ass, gave her a playful spank, and then pursued her into the house. They made a considerable racket as they worked their way from the front door through the house. I didn’t know how to respond to what was happening. As I heard them getting closer to the bedroom, a panic came over me, and I scurried into the closet and closed the door.

It was a strange reaction to what was rapidly unfolding, and I still can't quite put my finger on why that was my response. Perhaps I should have confronted them immediately, but I guess my thought was that I could catch them “red-handed.” I got on my tiptoes so that I could see what was going on through the louvered doors. Just as they rustled their way into the bedroom, I realized that I had left my shirt and shoes on the floor beside the bed. I hoped that they would fail to notice them in all of the excitement.

Rebecca’s blouse was fully unbuttoned, and her breasts were exposed. I could see no trace of a brasierre, so it had either already been removed or she hadn't worn one to meet her friend. The man was still fully dressed, other than an unbuttoned top button of his shirt and a slightly loosened necktie. I was shocked by how rough he was handling my wife, but I was even more surprised by how much she seemed to enjoy it. He placed his hands around her neck several times, not in an effort to choke her, but simply to demonstrate domination.

I watched as he rag-dolled her around the room, not stopping until he had stripped her completely naked. She was ordered to climb onto the bed, while he removed his suit coat and carefully cast it aside. He walked to the edge of the bed and barked at her to back up against him. Once she had complied, he unzipped his pants and maneuvered his cock through the fly. I was curious about how impressive the man was, but I couldn’t see anything from my line of sight.

As quickly as he pulled his cock out, the man grabbed Rebecca’s hips and slammed it all the way inside of her. I could see her tense up, and she let out a groan followed by a prolonged gasp. Once inside of her, the man unleashed a flurry of slaps to her backside. He didn’t stop until both of her cheeks were noticeably pink. Although Rebecca had maintained a nice figure over the years, her backside had become appreciably plump. This gentleman had obviously noticed that as well.

I couldn’t help but realize how different this interaction was from the ones that normally went on in our bedroom. The boring, repetitive nature of our sexual routine was never more obvious. With our busy family life, and with the children's bedrooms located next to ours, quick and quiet was the best way to describe our sex life. Most times, it simply involved me in some sort of dominant position, but not actually being sexually dominant. I recalled the first few times that we had had sex and how Rebecca wanted me to take it slow. Somehow, the thought that her needs would have changed through the years never occurred to me.

One other thing that had become quite evident was the fact that I was getting incredibly turned on. I felt wounded that my wife, the only woman that I had ever been with, was being unfaithful. Conversely, the way that my rigid cock had risen in a very uncomfortable position in my trousers was a constant reminder of how much I enjoyed watching her being taken by a stranger.

My legs were already starting to cramp up from standing on my tiptoes. I feared making any sort of movement that would alert them to my presence, but I had to shift around a bit. In addition, my erection was starting to become painful in its current state. Thankfully, I was able to free it up so that it pointed upward without bumping against the door. It was a relief to eliminate that increasingly uncomfortable feeling, but I had missed some of the action and was eager to witness how the rest of the encounter would unfold.

As the man started to thrust away behind her, I could see Rebecca reach her right hand between her legs. The man recognized that she was touching herself and immediately pulled her hand away. He grabbed both of her hands and pinned them behind her back with his right hand as he mashed her face into the mattress with his left. At that moment, it became apparent that she was his fucktoy and that he was not interested in her personal pleasure.

“You like that, don’t you, Rebecca? You like to be fucked like a whore, ” the man snarled.

There was a brief silence. Then, the man twisted her arms slightly and shouted, “Answer me!”

Although her words were muffled by the mattress, I could tell that she said, “Yes, treat me like a whore, Daniel!”

The escalation of their interaction, as well as hearing them call one another by name, was yet another blow that I had to sustain. It was at that very instant that I had previously imagined that I would burst from the closet and have my “A-ha moment.” Instead, I continued to stand uncomfortably and watch while my body nervously trembled.

He continued to berate Rebecca while he used her body as a plaything, often making her repeat humiliating things or say something to stroke his ego. One line that particularly struck a chord with me was hearing my wife say, “My husband could never fuck me the way that you do, Daniel.”

I watched as Daniel started to speed up. It was obvious that he was about to finish. I also realized that there was no way that he was using protection. I watched helplessly as he was seconds away from cumming inside my wife. He grunted several times loudly, much like I had seen in over-the-top porn climaxes. Then, he slammed his cock into Rebecca hard several times, just for good measure.

Daniel backed away, tucking his cock back into his trousers and denying me the ability to compare his size to mine. He grabbed Rebecca and shoved her forward, sending her sprawling and reiterating his apathy toward her. Daniel disappeared from my sight shortly thereafter. After a moment, I heard a familiar erratic splashing sound coming from the attached bathroom. It was obvious that he knew his way around the house. This was clearly not their first encounter. He returned to the bedroom, so arrogant that he didn’t even bother flushing the toilet. His shirt and tie were already straightened by the time he grabbed his suit coat. As he put the coat back on, he casually said, “Next Wednesday?”

Rebecca responded, “Yeah, sure, ” but it was her actions that I was focused on.

She had gathered herself while Daniel was in the bathroom and was sitting with her legs folded on the bed. She was rubbing her clit, seeking out the fulfillment that Daniel had intentionally denied her. Although I didn’t have the best angle to see her, the fact that she periodically licked her fingers indicated to me that she was tasting her own excitement, Daniel’s cum, or most likely, a combination of the two. It was never more apparent that I had just witnessed an exchange of sexual services and not a love affair, as I had originally feared. I waited until I heard the front door shut, then I stood up, swung the closet door open, and stepped out.

Rebecca’s face went pale, and she looked as if she had seen a ghost. She immediately ceased her actions as I slowly walked to the foot of the bed. Her labia was noticeably parted, and cum was leaking out of her freshly fucked pussy.

“Is that how you like to be treated?” I asked with unnatural calmness.

“Yes!” Rebecca fired back. “You treat me like I am some delicate little flower. I am not a seventeen-year-old virgin anymore.”

She was right. It would have been easy for me to have claimed that it was all her fault, but that is seldom the case in real life. We had allowed ourselves to drift apart sexually, and it threatened to tear our marriage apart.

“I can treat you like that, Becca, ” I retaliated.

“What?” she fired back, accompanied by an uncomfortable giggle.

I reached across the bed and grabbed hold of her left ankle. After dragging her toward the foot of the bed, I smiled and said, “Is this what you want?"

Rebecca bit her lip seductively and nodded. I unbuttoned my pants and quickly kicked my remaining clothing away. My neglected cock eagerly sprang free of its constraints, exposing to Rebecca just how much I had enjoyed the demonstration that she and Daniel had put on for me. I aggressively flipped her over onto her stomach and dragged her backward until she was bent over the edge of the bed with her legs spread wide. Her plump, pink ass drew my immediate attention as I peppered it with slaps until it had gone from pink to red.

“You are a naughty little slut, Rebecca, and I am going to make sure that you get everything that you deserve, ” I taunted.

As I slid my cock inside her, there was the unmistakable sensation that she had recently been fucked. For the first time in my life, though, that person hadn’t been me. I found myself strangely aroused by the thought of fucking my wife moments after another man had. While I had seen porn videos of “married men” in situations where they let other men fuck their wives, it never appealed to me until I actually saw it happen to my wife. I held her in the same off-balance position, restricting much of her movement as I continued fucking her. Extending my hand, I grabbed a handful of her hair, wrapped it around my fist, and pulled back.

As she let out a groan, I chastised, “You are a filthy fucking whore, Rebecca. From now on, you will take it however and whenever I want, and you will thank me for it. Do you understand?”

“Yes!” she cried out in a strained voice.

I decided to turn things up a notch since we were both having fun. I forced my thumb inside of Rebecca’s mouth and ordered her to suck on it. After a brief moment, I removed my thumb from her mouth and relocated it to its final destination. With one firm shove, I slid it halfway into Rebecca’s ass. She tried to squirm away as she groaned, “You motherfucker!” in my direction.

To be fair, it wasn’t a complete surprise. Although she didn't like anal sex, Rebecca wasn’t opposed to a thumb in the bum every now and then.

“Yeah, you like that, don’t you, Becky?” I teased. I was pushing multiple buttons at the same time, particularly because calling her Becky was usually a good way to take a knee to the nuts.

She let out a noise that vaguely resembled, “Yeah.” I could tell that she was enjoying a bit of pain with her pleasure.

“Beg me to stick my thumb in deeper and fuck you like the dirty whore that you are, ” I ordered as I twisted her hair once again.

Rebecca eagerly acquiesced and took it even further. She rambled on about how she needed strange men to use her sexually. Then she begged me to make her pay for being unfaithful.

Unable to contain myself any longer, I started to thrust away with reckless abandon. I imagined myself looking more like some wild animal engaged in a mating ritual than a married man fucking his wife on a Wednesday afternoon. My frenzy continued until an incredibly explosive release took my breath away.

Panting like a dog, I realized that I had left Rebecca just as unsatisfied as Daniel had. Not content with that result, I continued my dominance over her. I climbed on top of her with my body offset to her left side, pinning her down. Now in control of everything but her feet, I slid my hand between her legs and started to rub her clit from beneath.

Once I was sure that my hand was “on target, ” I started to interrogate her. She admitted to having a weekly appointment with Daniel for roughly two months. I also got her to confess that she had slept with two other men before Daniel, but they were each a one-time affair. Rebecca continued to cry out other self-deprecating things as her orgasm approached. She started to whimper, and her legs kicked wildly off the edge of the bed as she came. At one point, she nearly bucked me off, but I managed to stay on top until she finished.

As I rolled off her, we were both exhausted.

“Why didn’t you tell me you were such a filthy whore years ago?” I asked.

She responded, “I would have if I had known that you were willing to do that.”

Unfortunately, we had little time to recover; the kids would be arriving home soon. We showered and got dressed before they landed, and the focus shifted entirely.

Late that night, Rebecca and I had a pretty detailed discussion. Much to her surprise, I asked her to continue seeing Daniel, at least for a few weeks. I told her that I wanted to set up a motion detection camera in the corner of the bedroom. That way, I could record the two of them, and we could watch it together. That led to some fun moments, but after a handful of sessions, it was time to kick Daniel to the curb.

As the sexual rush of the "Daniel experiment" waned, we discussed finding a new suitor for Rebecca to help restoke the fire. One evening, as we were taking a leisurely walk through our neighborhood, we bumped into a young, African American man washing his car in the driveway. I couldn’t help but notice that he was staring at Rebecca’s round backside. The outline of the impressive package beneath his damp basketball shorts convinced us that he would be the perfect replacement for Daniel. All Rebecca had to do was cast her lure and reel him in.
