Mary contacted Matthew, using the dating app, to meet up for the following weekend. He said he was happy to meet again and that they could meet as many times as she wanted. He said he had really enjoyed meeting her and would like to continue dating.

Once the date was confirmed, Mary and I had a conversation about how to introduce myself to Matthew and what changes needed to be made to the meetings.

"Mary, we need to agree on how to introduce me to Matthew and what to say to him. He thinks you are a single woman. He needs to be told that you're married, that your husband knows you've had sex with him, and, besides, that I'd rather be present than not know what's going on."

"Yes, of course, Charley. How do you think we should do it?"

"Maybe talk to him at the bar about the fact that I exist; reassure him that I'm aware and not mad at him, and that it was a fantasy of yours to fulfill; that we want to continue the game, but now with me present."

"He won't be angry? Maybe he'd rather not continue."

"It's possible, but what else can we do? Keep seeing him on your own?"

"No; certainly not. I would like it to be something for both of us. Once I've tried it on my own, it would seem selfish to go on like that. I've already satisfied my fantasy. Besides, I want to share the experience with you."

"Maybe he'll agree to continue but impose conditions or limitations of some kind."

"If there aren't too many, I think we can accept that. Better that than to look for someone else now who we don't know what he will be like. In his case, he's attractive and very different from you, and having sex with him is very satisfying."

Mary's words caused me to be unable to stop myself from replying to her, slightly wounded in my self-love, "I don't know if he is too attractive and satisfying for my peace of mind as your husband."

She responded with an understanding smile and a caress on my cheek, saying, "Well, if I buy a vibrator, I want it to be a good one. It wouldn't make sense to go on this adventure with someone unsatisfactory. How many times do I have to tell you that I am not interested in him, nor will I ever be interested in him as a man? I love you with all my heart, and I enjoy sex with you very much. This is just a game with someone who is very different from you. I would never give up my 'apple pie' for anything in the world," after which she hugged and kissed me.

"Another thing, shall we tell him our real names?"

"I don't think so. This is just a one-off relationship; we're not going to be friends. If we get tired or something 'goes wrong', we break up, and that's it. We won't have to see him ever again or interact with him."

"OK then. Next Friday, we both go, and I can wait at the bar at another table. You tell him about me, explain the situation, and then I'll come over and the three of us can talk," I concluded.

During the week, we continued our tease and denial games, and, as before, Mary was not referring to Matthew to provoke me but to what she and I were going to enjoy with the 'reunion' afterwards.

As Friday approached, I wondered if I had been right to accept Mary's continuing to date Matthew. I couldn't help but dislike seeing her with another man, despite the arguments in favour, such as Mary's satisfaction, the rationalisation that it shouldn't be considered so important, or the pleasure and excitement we both experienced afterwards. At times, I thought I would almost prefer Matthew to say he was no longer willing to continue on those terms. At other times, I reconsidered that it was just a game, and for a limited time, that we were having a good time, and better that than the risk of falling back into monotony.

Friday came, and, like the previous Friday, we headed to Matthew's town, to the same bar as last time, next to the motel. We both disguised ourselves as Molly and Buck, she with her ginger hair and green eyes, and I with my wig and beard. Since I wasn't going to be in bed with Matthew, there didn't seem to be any danger of him finding out that I was wearing the wig and beard.

She headed to the bar and went in first. I followed shortly after, to go in separately so that Matthew wouldn't see us together before she explained the situation to him.

She had sat down at a table and was alone. I sat at a nearby table, where I could see her and respond to any gestures she made to me.

Almost immediately, Matthew arrived, walked over to Mary's table, gave her a hug and a kiss, and sat down next to her.

Mary started talking, and I could tell he was looking surprised and worried. At one point, he even looked like he was about to get up completely, but he sat back down again. Shortly after, he stood up and began to look around.

Mary then beckoned to me, and I stood up and walked over to her table. Matthew then noticed me and followed me with his gaze until I sat down at the table, in the vacant chair next to Matthew and opposite Mary.

I introduced myself: "I'm Buck, Molly's husband."

"I'm Matthew. Molly was just explaining your game to me. So you knew last Friday that she was fucking me, and now you both want us to keep doing it but have you present."

"Yes, that's right," I replied, "we want to add a little 'spice' to our sexuality and are exploring different games and experiences."

"From what I've read in erotic stories, you're a cuckold. I guess she's not sexually satisfied with you and needs someone to fuck her 'for real'."

"No," replied Molly. "I'm very satisfied with Buck; it's just that we want to seek out new experiences."

"Yeah, I get it," Matthew said, although I clearly sensed that he was convinced that Molly was sexually dissatisfied and that she needed him to fuck her.

"Well," Matthew continued, "I don't mind him being present, but I don't want Buck involved; it's not a threesome. Buck has to be totally out of the way so that he can see, but we don't see him, hear him, or distract me."

"Not a problem," Molly replied, "he would only have sex with me when you were done. Besides, he couldn't; one of the games we play is that he wears a cock cage all week, and I only take it off when you're done, so I can have sex with him."

Matthew said, with a smirk, "You're 'dirtier' than I thought. And it certainly confirms to me that you're a real cuckold. All week without being able to fuck, waiting for a real man to fuck your wife."

Again, I didn't try to explain any of the nuances or bring him out of the clichés he had read.

Matthew continued, "Well, that also solves another of my concerns. If I wasn't going to be fucking another woman during the week, I didn't want Molly to be fucking another man. If you've got your dick under lock and key, there's no longer that problem. In addition, since Buck is going to watch me fuck Molly, I want to be able to watch him fuck Molly."

I replied, "Fair enough, I can't say no."

"I guess that's no problem then," Matthew said. "Furthermore, since you two want to seek out new experiences, I'd like to be the 'master of ceremonies'. When we get together, I can propose new activities or games. Only Molly will be able to decide whether or not to accept, since Buck is as good as gone. And if Molly decides she doesn't want to participate, we'll stop seeing each other on Fridays and end the meetings, okay?"

Mary and I looked at each other, confirmed with our eyes that we agreed with Matthew, and we both said, "Okay."

"Finally, if Molly learns any sexual techniques or tricks to increase her or my pleasure, while we are seeing each other she will only use them on me, never on Buck. Promise?" added Matthew.

Again, we said yes.

Matthew got up, saying, "Well, let's go to the motel; I've booked a room like last time."

Molly and I got up, and the three of us headed for the motel, with Molly between us. Matthew had put his hand on her shoulder and adopted a possessive attitude. I was thinking that 'the time of truth' had come and how I would react to seeing her fucking another man, no longer just hearing them.

As we entered the room, I took a closer look at the layout. To the far right, just below a window, was a table with a chair, where you could write or put a computer; to the left, a large wardrobe or dresser, with slatted doors; in the middle of the room, attached to the left wall, the bed, where Mary and I had enjoyed ourselves, and where shortly, I thought, I would see Mary and Matthew; in front of the bed, a shelf with a TV set; to the left of the entrance, creating a corridor at the entrance, was the bathroom, with a door facing into the room.

I walked into the room and stood waiting.

Matthew said, "The dressing room is big. If we put the chair in, I think Buck could see everything from inside through the slats. And by closing the doors, he wouldn't be seen."

Without waiting for a reply, he moved the chair inside the dressing room and pointed to a place for me to sit.

I sat in the chair, and Matthew closed the doors. I checked that I could see the whole room through the slats in the doors. I realised that the door could not be opened from the inside, but, if necessary, with a few strong pushes, I thought I could get out. It was a fairly large space that even contained a folding bed, surely designed to be able to be opened and sleep a child accompanying his or her parents on a trip.

I paid attention to what was going on inside the room. Matthew walked over to Mary, who had put down her bag, hugged her tightly, and kissed her intensely. Mary kissed him back, but she seemed a little reluctant. I couldn't decide if it was because she knew I was watching the whole thing or because the kiss seemed like an act of love and they were not.

He began to run his hands all over her body, groping her breasts and ass. After a while, he began to take off her clothes, and she responded by taking them off him. Before long, they were both totally naked.

I have never been attracted to men, but seeing Matthew naked, I could understand Mary feeling a physical, instinctive, animal attraction to him.

It has always been said that swimming is one of the most complete and body-shaping exercises, as it works a lot of muscles in the torso and limbs, and it was certainly true in his case. He had a very muscular body, with broad shoulders, without a drop of fat, and strong legs and arms, but without that almost deformity that you see in those athletes who stuff themselves with steroids. He reminded me of images from a series I'd seen on TV about Vikings, with strong, lithe bodies shaped by hard work, life in the open, and life-and-death struggles. Equally, his hands were big and strong, hands that had already caressed Mary's naked body and would enjoy it again soon. Perhaps the only thing that was different from that image of the Viking warriors was the hair and beard, for Matthew had no beard and very short hair.

She was as beautiful as ever. Her body did not detract from his.

Matthew directed Mary to the bed, where she lay down. He positioned himself on top of her and began to lick her breasts, moving from one to the other and lingering on each one, nibbling on the nipples. She closed her eyes and let herself be carried away by the sensations and the pleasure it gave her.

I imagined my mouth on her breasts, their soft touch, and the pleasure I always got from licking them, and quickly my cock tried to get erect, to hit the firm limits of the cock cage. Not being able to lick them and not even being able to get an erection made me want her even more and feel a huge envy for this man who was enjoying, in front of me, Mary's body.

He kept caressing her body, his hands going over her shoulders, her thighs, and her breasts, pinching her nipples hard. She was getting more and more excited, her mouth ajar and panting, her breasts and cheeks flushed, and her nipples erect.

My frustration grew as I watched them enjoy themselves, and I felt only a growing pain in my crotch, caused by the blood trying to flood and expand my cock, which only served to collide with the bars of my cock cage and to pull painfully at the ring behind my testicles.

Finally, he repositioned himself so that his cock was right in front of Mary's pussy. I then noticed that, as Mary had said, it was not much longer than mine, but thicker. She spread her legs to facilitate penetration.

Matthew then said, "Molly, I've been dreaming all week of putting my cock back in your soft little pussy, my kitten's pussy."

He began to slowly push his cock into Mary's opening, and Mary began to emit a guttural moan. He lay with his arms resting on the bed, on either side of her head, and looked down at Mary, proudly watching her expression and how she was enjoying the penetration, keeping her eyes closed. When he had his cock fully inserted into Mary's body, he turned to me and looked at me with a look that seemed to me to mean, 'Watch me fuck your wife; I have my cock deep inside her pussy; watch her enjoy me.'

Maybe it was my interpretation, and he just happened to be looking at me, but I couldn't help thinking about it.

Matthew began to partially withdraw his cock and reinsert it, each time with more and more momentum, moving Mary's body and making her breasts sway. She let herself be fucked, enjoying the sensations that must have come over her. His pace quickened, and I watched as his ass and hips moved, thrusting hard into Mary. She clung to him with her arms and legs and began to mumble between gasps, "Yes, yes, keep it up.... Fuck me hard, Matt... yes... like this... ohh... yes... fuck me... yes... I'm going to cum... yes... aaarrggg..."

Finally, she came, arching her back and letting out a scream.

Again, Matthew looked at me as if to say, 'Learn to please your wife. Watch her cum when I fuck her. Watch her enjoy me.'

For my part, my cock was about to explode. Without realising it, unconsciously, I had been stroking my cock and testicles through my pants. I couldn't tell if it was a way of easing the tension and discomfort of the cock cage or an attempt at masturbation. I had been oozing a lot of pre-cum, and I was quite wet.

I couldn't help but get aroused by this erotic spectacle that was taking place in front of me. Two beautiful bodies are enjoying wild sex. In my head there were many different thoughts, like: 'Why do I let that man fuck Mary?', 'That beautiful and exciting woman is my wife, and she has chosen me to live together; I'm lucky', 'I love her so much that I don't mind her enjoying her fantasy', 'It's really no big deal; it's just a physical thing, just like she enjoys a vibrator', 'I'd like to be the one who was there.'

He continued to fuck her as she chained orgasm after orgasm without stopping. When she finished and caught her breath, she opened her eyes, looked at me with a look of love that melted me, and said silently with her lips, 'Thank you. I love you.'

He continued his thrusts until he pushed his cock all the way in, stiffened, arched his back, threw back his head, closed his eyes, and he reached a strong orgasm as his testicles injected, for a long time, streams and streams of his semen into my wife's open vagina.

He collapsed on top of her and looked at me again with satisfaction, as if to say, 'I have already filled her pussy with my semen. Once again, I came inside your wife'.

As before, I didn't know if it was my imagination or if he really wanted to convey that message to me.

After a while, he lay down next to her, and they lay in each other's arms, recovering.

I had hoped they were done, but I knew they weren't.

After a while of rest, he said to her, "Get on top of me and ride me."

She rose up on her knees, and since he wasn't erect, she moved her head to his cock, took it in her hand, and began to lick it. I thought that maybe, for the first time, she was tasting her own fluids mixed with his semen.

Little by little, he regained his erection. Then she positioned herself with her knees on either side of his body, took hold of his shaft with one hand, placing it at the entrance to her vagina, and began to descend very, very slowly, impaling herself on his cock. I could see his thick member pushing its way in and dilating her vaginal lips. Being penetrated and dilated by his wide cock was clearly turning her on. She was enjoying the sensation with her eyes closed, enjoying every inch of his cock as it pushed inside her.

When their pubes touched, she began to rise again, savouring the sensation and feeling his thick cock pull her slit and lips downward. When only the tip of his cock was inside her, she moved back down, again very gradually.

She had moved her hands to her breasts, fondling them and pinching her nipples with her thumb and forefinger as she moved up and down, very slowly but steadily.

He stood with his hands behind his head, relaxed, confident, watching her beautiful body, and proud of the pleasure she was getting from his cock.

Again, he looked at me as if to say, 'Look how she likes my cock. Yours doesn't satisfy her enough.'

I knew it wasn't true that she thought that, and I wasn't even sure he looked at me thinking that. Maybe it was insecurity or fear that she might actually think it.

I was excited again, watching her enjoy herself. My cock, which had calmed down a bit when they stopped, was again fighting desperately and futilely to reach erection inside the cock cage.

She began to vary the rhythm, rising very slowly but descending all at once, impaling herself hard, thrusting his cock in fast and hard, until one of the times, descending to the bottom, she remained still and let out a sort of gurgle through her half-open lips, a sign that she had reached an intense orgasm that left her overwhelmed.

He grabbed her hips and began to guide her body up and down the length of his shaft forcefully and vigorously, almost as if he were masturbating with her body. She let herself go, her hands resting on his chest for support. Every now and then she let out another gurgle, probably signalling another orgasm.

Finally, he came again, ejaculated inside her, and released her hips. She dropped down on top of him, her breasts resting flat against his torso.

Soon she rolled over next to him, rested for a few minutes, and got up to go to the shower. From my position, I could see the shower. As she had left the bathroom door open, the shower was in front of the door, and my dresser was in front of the bathroom door.

Again, I admired her body as she showered and thought that at last, after a week of waiting and teasing and suffering the pain of seeing her enjoying another man, I could make love to my darling Mary.

She came out of the shower naked, tapped Matthew on the shoulder, saying, "You can shower now if you want," and walked over to where I was.

She opened the door, hugged me, and said in my ear, "I love you so much. I can't tell you how much. You are the best man in the world."

She went to her purse, took the key to my cock cage, and released my cock, which quickly became erect.

Seeing the erection, and especially noticing how soaked my briefs were and the amount of pre-cum I had leaked, she said smilingly, "Looks like someone got really turned on watching me have fun."

"Yes," I replied. "Watching you enjoy yourself and thinking about being with you and making love to you has really turned me on."

In the meantime, Matthew had gotten up and gone to the bathroom.

I hugged and kissed Mary passionately and eagerly, with a mixture of sexual excitement and tenderness.

We moved to the bed and rolled onto it together together.

My whole body was eager to feel Mary's skin. As I caressed her all over her body with my hands, I felt her skin on my whole body, with my legs, my torso, and my arms. My skin was like an amplified receiver of sensations. I enjoyed her touch and her body immensely, and what is better, I seemed to notice that the same thing was happening to her. Our bodies wanted to feel each other's.

I lay over her and gently pushed my cock into the opening of her vagina. Her channel was wet, warm, and soft. The pleasure I felt as I gently penetrated her was indescribable. All the unsatisfied desires of the week, multiplied by what I had seen tonight, increased my pleasure.

She whispered to me, in a warm voice, "Fuck me; I love it when you penetrate me; I love you."

Slowly, I sped up, eager to cum, and burst at last after so much waiting. She was highly aroused and looked up at me with bright eyes, nostrils flared, and cheeks flushed, approaching orgasm right next to me. I had my elbows resting on the bed, one hand stroking her hair and the other caressing her breasts.

My rhythm accelerated, and I felt that I could not hold any longer. I pushed my pelvis to the bottom, and I felt how my testicles contracted and my urethra was run through by a fiery stream of semen, which seemed to never end. It was an overwhelming, gigantic orgasm, and for a while I was not aware of anything. I only felt that Mary was also reaching orgasm with me. We felt totally united, both physically and mentally. I let myself fall on top of her, both of us breathing hard, sweaty, and happy.

Out of the corner of my eye, I noticed that Matthew had come out of the bathroom and was watching us. It was a strange sensation to be watched while making love, which made me uncomfortable, but the truth was that I hadn't even noticed until that moment, and the extraordinary pleasure I had felt made any small annoyance negligible.

Besides, I thought, with a mixture of pride and competitiveness, 'Look how she enjoys me. We are a couple, and you are a stranger. We have something special. She's my wife.'

Matthew got dressed and left. We lay in bed, frolicking, caressing, and kissing. We fell asleep without realizing it, as if flying on a cloud.

The next morning, we rested, made love again, and after showering and putting on my cock cage, we went to breakfast.

In the car, more intimate than in a bar, we discussed how we had enjoyed the previous night's encounter.

"Well, did you like the experience?" said Mary.

"Yes, it was extraordinary. I felt really good with you, and the orgasms were fabulous."

"For me too. Did you have a hard time watching me have sex with Matthew?"

"I must admit, although I try to rationalise that it's for your enjoyment, that it's just sex, a physical thing, and that there is no relationship between you, I have a bit of a hard time when I see you enjoying yourself so much with him."

"I'm sorry; I don't want you to suffer. We can stop," Mary said with a tone of some regret.

"No, you're enjoying yourself, and I'm really enjoying myself. I don't know if it's the desire that's built up over the week; from seeing you naked, aroused, and cumming; from envy and jealousy of Matthew; from the excitement of doing something sinful or forbidden; from how excited and grateful you are when we make love; or from a combination of all of them, but the fact is that the encounters we're having are the best in a long time. I enjoy them so much and feel as much in love as when we were college sweethearts."

"I'm so glad, Charley. I feel the same way too."

"If someone had told me a few months ago that we would be doing this, I would have said he was crazy, but a few months ago we were in a monotonous and grey world. We made love only once a week, and it wasn't even comparable to what we're feeling now."

"So you think we should keep seeing Matthew?"

"Yes, let's go on for a while, until we get tired of it or want to try something else," I added, grabbing Mary's arm.

We both looked at each other lovingly.
