In recent years, we realized that we simply can't put out of our mind our first, and so far our only cuck session. To explain, my wife Kate and I are now in our early forties, and we have two daughters a normal lifestyle, and our sex life is mostly vanilla, but it was not always that way.

When we were in our mid-twenties and our first daughter was around three, we went on a family holiday to Crete. It was our first time away since getting married and our first holiday abroad. We had decided a few months earlier that during our holiday we would try for a second child and Kate came off the pill in February as we were holidaying in August.

For the time until our holiday, I used condoms so that we would not complicate things if Kate fell pregnant sooner and experienced morning sickness on holiday. I was so looking forward to our holiday and getting to fuck my wife bareback once again!

When we arrived at our holiday apartment we were amazed by the weather, the vibe in the resort, and our apartment complex which was very smart apartments surrounding a communal swimming pool. The first few days we spent around the pool, I would watch over our daughter and let Kate get some rest and sunbathe.

Kate had bought several very sexy bikinis to wear, she had lost her baby tummy since having our daughter and was looking every bit the hot milf. I couldn't help noticing many of the guys around the pool checking her out. Strangely I was not jealous or angry, it just turned me on thinking about the guys getting aroused by her.

One guy made a move to chat with us, he was called Mike, an English black guy aged forty-five who was working in Crete for the season. He had a few day's leave so was spending it at our complex as he knew the owner and had a free apartment for the week.

It turned me on to sit there chatting with Mike and Kate, knowing he was looking Kate up and down and probably imagining her naked under that bikini!! I made a point of leaving them alone while I took our daughter to play in the pool, I could then watch from a distance as they were chatting.

As the day went on, Kate became increasingly flirty with Mike and we all had some drinks around the pool. Later I took our daughter back to the apartment to give her dinner and put her to bed, saying to Kate and Mike that if they wanted to finish up their drinks and chat why not both come back to the apartment when they are ready?

An hour or so later they both arrived at the apartment. I had put our daughter to bed, so we were all able to relax in the main lounge area and we popped on some music and topped up our drinks. Mike was asking about how we met, and how long we had been married, during our chat I could see that Kate was enjoying the attention that Mike was giving to her body.

Kate was still in just a bikini, and Mike was enjoying the view, then I noticed that she was deliberately teasing Mike by leaving her legs slightly parted, and sometimes leaning right down so her cleavage was fully showing, this had me beginning to get hard. I had never previously experienced the feeling of getting turned on by my wife flirting with another guy, it was strange but incredibly arousing.

I can't remember what the trigger was, but after a couple of hours and a few drinks things heated up quickly. Mike was now on the sofa with Kate and in a moment they went from chatting to Mike leaning forward and kissing Kate on the lips, as he did this the room went quiet and I don't think any of us knew what to do next, it was so unexpected. Kate and I looked at each other wondering what to do or say, then I found myself simply winking at her and saying, "Go for it."

In the next moment, Mike kissed her again, and his hands were all over her. I sat there with my cock hardening like a rock as I watched this older black guy ravish my wife. I began to wonder how far it would go, my thoughts were soon answered when I saw Mike's hand disappear between Kate's legs and his fingers worm their way inside her bikini bottoms. I thought, is this really happening, my wife making out with another guy, a stranger, and right in front of me?

They continued to get more and more involved, and in no time Kate's bikini top and bottoms were off and so were Mike's shorts, they were laying on the sofa and she was jerking his big black cock with her hand. I remember seeing her engagement and wedding rings glistening as she jerked him.

Next Mike moved up over Kate and positioned himself between her legs, it was clear that he intended to fuck her, as I was busy watching them both and wanking my cock, she looked directly at me seeking my approval, I simply nodded yes with a big smile on my face.

She then said to Mike that he needed to wear a condom, as she was not protected. He asked if we had one, but of course, as planned we had not brought any condoms away with us on the trip. There was a very awkward moment, but I was so turned on by the situation that I said to Kate it was up to her if she wanted to let him go bare, as long as he pulls out well before he cums. Kate looked at me smiled and slowly guided his bare cock into her pussy.

It was incredible, I was watching a bare black cock slide into my wife's fertile pussy, and I was hard as a rock with my heart beating out of my chest. He fucked her slowly, making sure she was enjoying it. As he worked his cock deep inside her, they continued to fuck for about twenty minutes. Mike moved Kate into the doggy position, and she looked straight into my eyes as he got behind her and once again fed his bare cock into her.

We were both completely absorbed by the experience, it did not seem real. Mike then said to Kate that he was close to cumming, and to my relief, she asked him to pull out. Like a gentleman, he obliged and slid his glistening cock from her pussy, and she rolled her onto her back beginning to jerk his cock. Almost immediately Mike began to cum, jetting large spurts of his virile seed all over Kate's tummy, pussy and even some up as far as her tits.

I wanted some action myself now having just watched Mike and Kate at such close quarters, and as Mike slumped back into a chair, I got onto the sofa with my wife, Mike's cum rubbing between us as I lay on top of Kate and slid my cock inside her. Her pussy felt different, I guess stretched from the fucking Mike had given her. We were kissing and she was rubbing Mike's cum into her body between us when I felt her cum-covered hand reach her pussy and grab my cock as I plowed into her, I realized that she was rubbing his cum into her pussy and onto my cock, which in turn was pushing his seed deeper into her pussy.

This did it for me and I blew the biggest load up her pussy, just as she orgasmed. As we looked into each other's eyes, we both knew what we had done, and the risk involved, yet it seemed to tip us both over the edge and turn us on tremendously. So that was the end of our first session, but it was not long before things heated up again.

After Kate and I had both cum we continued to kiss and discuss what had just happened. Mike called over to ask if we were okay and we looked at each other then looked at him and said, "Yeah all good".

I whispered to Kate, "Are you okay?"

She kissed me deeply and said, "I'm very okay, that was amazing! Please don't be upset with me."

I reassured her that I found it hot as hell and I had encouraged her to go with Mike, so it was a joint thing. I asked her about her rubbing Mike's cum in her pussy and on my cock, I said, "Are you okay with it, don't forget you're not on the pill anymore?"

She said, "I don't know what possessed me to be so reckless, but fuck it was hot."

I said hell this is a one-night-only thing, let's live it to the full so I told Kate it was okay with me if she wanted to play some more and not to worry about condoms.

At this time Mike joined us on the sofa so I retreated to the chair and watched as he fingered her pussy, and they began to make out again. This time Kate lowered her head to suck Mike's cock hard, she worked hard looking like such a slut slurping at the stranger's hard black cock. Mike lay flat on the sofa and Kate was between his legs sucking, then once he was hard, she moved up his body and began to kiss him and rub his chest. She then looked at me for reassurance.

I whispered to her "It's okay – go for it."

She then leaned forward grasping Mike's cock in her hand and guided it back into her pussy. Once again, I watched Mike's bare cock slip into my wife, his shaft glistening with her juice, she started to ride him slowly. I moved from the chair to sit next to them on the floor so I could see close up as her pussy stretched over his big black cock.

This was wild - what the hell was going on, how had we ended up in this scenario? I didn't know any answers, all I knew was that I was hard as a rock watching my wife pleasure herself with a guy we had only just met and that his bare cock was at this moment sliding in and out of her fertile pussy.

We both knew the risk; she was close to her fertile period as we had purposely arranged the vacation to coincide with her ovulation. So, this was mad, a stranger's bare cock plowing away at her while I sat next to them wanking. I wondered what she would do when he was ready to cum.

As Mike had already cum once he was able to last longer and Kate was riding him so hard, bouncing right down on his shaft to jam it as far up her pussy as she could. I told her how hot it looked, and this encouraged her to be sluttier, she started to talk with Mike asking him "Does it feel good fucking a married pussy" and "Don't forget you will need to pull out as I'm not on the pill".

She also told him I was watching and wanking my cock as I was enjoying the view. After a good 20 minutes of the best fucking Kate has ever had, Mike said he was getting close to cumming. Kate then turned to me and said (loud enough for Mike to hear) "Well what do you want to see, where do you want him to cum, this is for you too."

FUCK I could hardly breathe, was my wife asking if I wanted to watch a stranger, a black guy at that, cum in her when she is totally unprotected and fertile.

I couldn't control myself. I was jerking so hard and said, "Baby let's do it, just this once - do it for me."

"Are you sure, you know where I am in my cycle?" came her reply as she continued to ride Mike's cock.

Mike then started to squirm and said that he was close now and should he pull out. Kate and I locked eyes, and she knew what I wanted to see, and I knew what she wanted to feel, and in that moment, she leaned forward and told Mike "Don't pull out, fill my slutty pussy - cum in me please."

That was all the encouragement that Mike needed, and he began to pump a huge load directly up inside Kate's fertile pussy, spurt after spurt and she rode it like a bitch on heat. I could see some of his cum around his cock as it went in and out, fuck we had done it!!

Kate sat firmly on Mike's cock until he went completely soft then eased off so I could see the huge cum load in her pussy. She then laid down and beckoned me over and I knew what we both wanted as I mounted her and fucked my cock into her cum filled hole pushing Mike's seed as deep as I could as we kissed passionately.

So we had really thrown caution to the wind in the pursuit of sexual satisfaction, in a very short time Kate had gone from being a normal mother and wife into a cock hungry slut willing to fuck with a stranger in front of her husband, and I had transformed from a dedicated husband and father into some sort of cuckold pervert wanting his wife to be used for a stranger's pleasure, and even encouraging her to fuck unprotected.

As we lay there in the aftermath of the amazing sex session with Mike, and with Kate's fertile pussy awash with billions of his sperm, we continued to make out, still highly charged from the situation. Kate whispered to me, "That was amazing, can I have more?"

I smiled and winked, "As long as Mike, is gone by morning."

On hearing that Kate kissed me again and started to jerk my cock which was already getting hard again. Mike was in the chair watching us and Kate turned to him and asked if he wanted to stay a little longer, he immediately began to rub his cock and said it would be a pleasure.

Kate and I were on the sofa, and I sat while she lay across my lap and began sucking my cock, all the while looking up at me. I was reaching down to her pussy and fingering her soaking hole, playing with Mike's cum as it was seeping out. Mike asked if he was okay to join. I looked at Kate and she removed my cock from her mouth and turned to him saying "Definitely," winked at me, and went back to sucking my cock which by now was almost rock hard again.

Mike got on the sofa behind Kate and took over from me fingering her pussy, it felt natural for me to simply remove my hand and give him access to my wife's pussy. Watching him explore her pussy was amazing and she squirmed and wriggled in pleasure while still sucking my cock. We all naturally moved our positions slightly, so Kate was still sucking my cock but now she was kneeling on the sofa with her pussy exposed to Mike who was immediately behind her.

Kate was looking up at me, as Mike began to rub his stiffening cock up and down her married pussy. He was teasing her, and me as I could see his bulbous cock rubbing Kate's well-used pussy. He leaned forward and asked, "Is it okay, I can pull out whenever you want?"

Kate looked up at me, I smiled and told her "There's no need for pulling out tonight "

With that, she eased back onto Mike's cock encouraging him to start fucking her from behind. In this position, his cock reached deep inside Kate's, and she winced a couple of times as he drove slowly but deeply inside her. All the time she continued to dip up and down on my cock with her mouth. I could see her pussy clinging to Mike's cock as he fucked her with increasing purpose.

We both knew the risk we were taking. Kate was not on any birth control and well into her fertile time of the month, yet neither of us wanted the night to end. In my mind, I was thinking that any damage was already done from Mike's huge load he had pumped in her earlier so pulling out now was futile, we may as well both enjoy the taboo thrill of unprotected sex.

Mike was being a gentleman as he fucked Kate. He regularly asked if she was okay and even looked at me checking that I was okay with him fucking Kate, each time I would simply nod my approval and occasionally say things like "Fuck her for me" and " Give it to her deep".

The session extended in this way for twenty minutes, and both Mike and I were nearing our climax. I said to Kate that I was close to cumming, and Mike said he was also close. To my surprise and disappointment, Kate said to him to pull out of her, which he did and then she sat up removing her mouth from my cock. I was wondering what was happening, however, it was soon clear when she got to the floor on all fours and asked Mike to get back behind her so she could feel him deep inside while I watched from the sofa. I sat there jerking my cock, edging towards orgasm as Mike fucked Kate hard.

It was not long before he was nearing his orgasm and he told Kate, "I'm close."

Kate looked at me jerking my cock and asked, "Ok honey, it is up to you, do you want Mike to pull out?"

Her question nearly made me cum on the spot, and against all sensible thought I clearly said, "No baby, I want to see him cum deep in you."

She replied, "Are you sure honey, this can't be undone?"

I was quick to reply, "Please honey do it for me, risk it."

Kate immediately looked back over her shoulder and said to Mike, "You heard my husband, please cum deep inside me, do it, fucking use this pussy!"

As you would expect that was all the encouragement he needed and within thirty seconds he was driving deep into Kate, grunting, and pumping his fertile load deep inside my wife for the second time that night. Making sure that I could see and hear as he sprayed his cum as far up inside Kate as possible. Simultaneously I blew my load all over my tummy, hand, and floor, the whole scenario tipped me over the edge.

As Mike finished, he pulled out his softening cock, and as before it was followed by the tell-tale pool of cum in Kate's pussy. Mike then said he should be going, it was getting very late, and he did not want to outstay his welcome, he grabbed his clothes and in an instant, he was gone.

Kate and I were left alone in the lounge. She looked at me and said "Oh my God, what have we done? I'm so sorry."

I hugged her close and said, "It's okay, we both wanted it, it was amazing, and it will be our secret, a one-night-only experience that we shall never forget."

We kissed and hugged, then went off to our bedroom after first quickly checking in on our daughter asleep in the adjoining room. Once in bed, neither of us could sleep, we kept talking about what we had done, how hot it was, asking each other what each of us enjoyed the most. Kate said she felt like a real woman, and it broke her out of the mummy/wife mode and liberated her. I said I felt amazing pride in watching as she fucked Mike, what a desirable woman she was, and how lucky I was to have her as a wife.

We then got to talking about the risk we had taken, Kate fucking Mike unprotected and during her fertile period. We both agreed that it was a huge turn-on for both of us, she said the taboo and risk just took over her and she knew it was wrong but needed to prove to herself she could do it. I said that it was the ultimate rush, watching and encouraging Mike as he fucked her, asking her to let Mike cum in her, and sitting alongside wanking as Mike filled her pussy with huge amounts of fertile sperm knowing that he could easily get her pregnant.

Whilst we both did not regret the evening, we both agreed that it should never happen again, it should remain a one-night thing. We also had the not-insignificant issue of what if Kate gets pregnant, as these were the days before the morning-after pill. We both agreed that we would abstain from sex for the rest of the holiday, or I would buy some condoms for me to use. That way, if Kate does fall pregnant, we would know it is Mike's and then we could decide the next steps.

It was an amazing few weeks, firstly the remainder of our holiday where we played the happy family as if nothing had happened when we were out for meals, I would get so hard thinking about the people we meet having no idea that Kate had spent an entire evening pumped full of a stranger's sperm as I watched and wanked.

When we returned home to the family it was a huge turn-on as we had dinner with Kate's parents, and our minds drifted back to the evening in Crete with Mike. As I looked at Kate chatting with her Mum and Dad, I was there feeding their grandchild and could not help but get incredibly hard wondering if a stranger's black baby was growing in their daughter's womb.

In the end, after a nervous, and to be honest exciting wait, Kate's period came, and our worry was over as quickly as it had happened. At the time Kate and I were relieved and Kate said that she would never do anything so stupid again.

However, as time has moved on, we can't get the images of that night out of our minds and we would do anything to experience something similar again, especially the pregnancy risk element. Kate gets incredibly aroused in bed when we discuss the night with Mike, and this has led to us planning ways to arrange another "One-night thing!"
