First things first, I love my husband; always have and always will. However, he opened up my eyes to the fact that I was what they call in Scotland, 'A good ride.'

I'm quite tall at five foot ten, and I've always been busty; hence the nickname BustyBeezy.

I met Rob first when he dated my elder sister at school.

I started dating him after we met in a bar when I was seventeen. He was four years older, and within three weeks of dating we were having regular sex.

I had lost my virginity a year earlier on a school trip to France.

It wasn't sweet or romantic; it was rushed, hurried, and awkward, and it hurt. But bless him, Harvey did his best. To be honest, it was disappointing, not at all what I imagined or hoped for.

My second sexual experience was with Adam, a year older than me and, more importantly, experienced. But unfortunately, still not a lover, just another trier.

Rob, however, was different; he was gentle. He knew how to excite me and tease me and, more importantly, he knew about oral sex.

Wow, what a game-changer that was. From the first time he went down on me in the backseat of his dad's car, I was hooked. I had never been so aroused in my life, and when he nibbled on my clit, damn, I had the best orgasm of my life up until then. That's when I realised sex was very enjoyable, and yes, we were both good at it,

I had always known I was attractive to men.

Within three years we were married, had our own flat, good jobs, foreign holidays, and had bought a second-hand car.

And the married sex was terrific.

Robbie, however, was always wanting to try new things sexually, and I wasn't averse to spicing things up in bed.

The one thing I drew a line at was having sex with someone else, but this seemed to be a particular fantasy of his, though to me, that was a definite no

But he just would not let it lie.

Every few weeks after making love, he would lie in bed and say, "I'd love to watch you being fucked." And each time I would steadfastly refuse.

However, of course, after a couple of years of marriage, I would be a liar if I said I'd never had thoughts about sex with someone else. And yes, occasionally I'd dream about having sex with friends or workmates. Unbeknownst to me, these thoughts gave Robbie a way in.

For a few months Robbie had constantly brought up the idea of a fantasy fuck. He wanted me to imagine that, as he fucked me, it was someone else, a friend, a workmate or maybe a celebrity.

He called this a 'fantasy fuck' and I must admit it did excite me.

He would make love to me, but I was to imagine it was someone else, and I'd call him that person's name. However, even though the thought excited me and I enjoyed the idea, I managed to keep this idea in his head and not our bed.

However, one Saturday night changed all that forever.

On this particular Saturday we went to a local club with some friends, and as was usual, going for a night out, I'd dressed accordingly.

Black lacy bra and panties lying under tight black satin trousers and a black silk blouse. Robbie always liked me in black underwear. I knew I was getting shagged that night when we got home, so I picked Robbie's favourite set. However, I didn't know what this evening would lead to.

In the club we met friends and workmates of Robbie's, one of whom he introduced as Davie.

He was about six foot two and very pleasing on the eye; he had just moved here from Edinburgh, so didn't really know anyone. So, Robbie had befriended him at work.

We got on well; he was good company, funny, witty and a good conversationalist. However, one thing was, he was very 'touchy-feely', as we say in Scotland. He would stand close and his hand would brush your bum or graze your breasts. To be honest, I enjoyed the flirting and didn't mind the groping.

I found it quite exciting.

Returning from the ladies' toilet, Davie was standing in the corridor waiting.

He started chatting to me, and the chat became very flirty. He told me, "You are really sexy, nice tits and you've got a great arse," And he patted my bottom.

I should have been upset about it, but I felt strangely excited. He then said, "I wish I could have a girlfriend like you. It's a pity you are taken, though." He leaned in and asked for a kiss.

Now I should have stopped him there, and then. But I was drunk and a little horny and was definitely enjoying his attention. Our lips met, and soon we were kissing hungrily, and as we kissed our tongues were exploring each other's mouths.

It was not just his tongue that was exploring, though.

Dave's hand was inside the waistband of my satin trousers, caressing my bum cheeks through my nylon knickers. He whispered in my ear, "I bet these silky knickers are black?"

I whispered back, "Yes, they are," as I panted with excitement, his hand gently massaging my bum cheeks. I can't remember how long we kissed; it seemed like an eternity, but eventually we broke off and returned to the club.

My panties were wet at the gusset, and I couldn't believe what I'd done, but strangely I wasn't ashamed, just excited.

The night carried on without any further incident, till Robbie and I returned home. I could tell he was horny, as in the taxi he fingered me in the back seat, so I knew I was in for a good fuck.

Once in the bedroom, he told me to strip down to my undies and get ready for bed. Robbie has a fetish for fucking me in my underwear, and I happily play up to it. So as I lay in bed in my black lacy bra and panties, Robbie joined me.

As we got down to getting dirty, he once again tried to get me to agree to his fantasy fuck plan. "Louise, would you be up for a little fantasy fuck?" he asked,

"You lie back, close your eyes, and imagine it's someone you like fucking you," he asked.

After what had happened earlier that evening, I was so horny and turned on that I agreed.

"God, yes, baby," I purred.

He was stunned and surprised but absolutely excited when I let it be known that I'd go along with his fantasy fuck idea. However, I told him one condition: I wanted to imagine it was his friend Dave who was riding me. He happily agreed, and he was like a man possessed. The sex was electric.

As I imagined Dave riding me hard, I climaxed over and over, and all the time Robbie thought it was him driving the fantasy, never suspecting that I was really enjoying it.

We both fell fitfully asleep, completely exhausted.

Next morning Robbie was like a dog with two tails. He was so pleased to have gotten his fantasy fuck plan to our bed. Obviously I never mentioned my fumble with Davie, but now my head was working overtime. And yes, I wondered about going further, but how would I get the opportunity?

I had to plan my path carefully, and Robbie in his innocence played straight into my hands.

He kept on the fantasy fuck path, and I happily played along as the sex was spectacular. So every couple of weeks I'd agree to a fantasy fuck, and imagine Davie fucking me all the while now longing for it to really happen.

Then, lo and behold, in the run-up to Christmas the opportunity arose.

We had completed another of our monthly fantasy fucks and were talking in bed, when Robbie raised the subject of me actually fucking someone else, and him watching.

God, I couldn't believe it. He was actually offering me the chance to live out my dream. But I had to be careful how I played this. I had to make it seem like it was his idea.

So of course I said a resounding no and acted hurt all the while secretly planning for it to happen, and planning in my mind how I could arrange for it to transpire, so that I could fuck Davie and make it seem like it was my husband's idea.

The opportunity arose when we had a Christmas night out at a local club, and Davie was there with friends.

Of course, when he saw us, he came over to chat, and we flirted a bit. Later, he came over and asked me to dance.

As we danced, he was a little drunk, and as we chatted, he told me he often masturbated imagining me in my black panties, and he really wanted to fuck me. So imagine his surprise when I replied with similar feelings, and laid out a plan for him to return to ours that night, and hopefully when Robbie fell asleep we could fuck.

He couldn't believe it and was right up for the plan. What we had to do now was convince Robbie.

When I returned from the dance floor, I then began to plant a plan in Robbie's mind that we could maybe get Dave to return to ours and see what might hopefully happen. Christ, he nearly exploded with excitement.

Later on, as Robbie went to the loo, Davie asked me back up to dance. On the dance floor we took the opportunity to kiss, and Davie also groped my bum cheeks as we danced. But out of the corner of my eye I spied Robbie returning from the toilet. He stood at the edge of the dance floor as we continued kissing and groping. I didn't acknowledge him, nor did he me.

Returning after the dance, I played dumb as did Robbie, but I knew he'd be horny as fuck and with the right encouragement I could get him to follow my plan as if it was his idea.

As the night drew to a close, he went to speak to Dave, and when he returned, he whispered to me that he'd asked Dave to share our taxi, and he'd agreed, and was I up for it when we got home? I coyly agreed if that was what he really wanted. Robbie readily agreed that yes, he wanted to watch Davie fuck me. Men can be so easily manipulated.

In the taxi on the way home, Robbie asked Dave if he fancied coming in to our place for some drinks, and he readily agreed. I was sitting in the back, smugly thinking I had manipulated these two men into doing my bidding, and I was going to get to fuck my fantasy with my husband's permission.

Once inside our flat, Robbie sat in the chair as Dave sat down on the couch, and I went to pour some drinks. I returned and handed Robbie his drink, then went and lifted mine and Dave's, as I sat down beside him on the couch. I decided it was time to see if my hubby was serious about following his fantasy through.

So I brought up the kissing and groping earlier that evening. I told Robbie, "Davie had asked me for a Christmas kiss, and I did, honey, but as we kissed I felt horny and slipped him my tongue."

Robbie bought into it, asking me, "Do you fancy Dave?"

"Mmmm, yes, honey, and I know he likes me because he felt my arse," I replied.

My heart was exploding in my chest as I replied.

Robbie then asked, "Would you like to fuck him, Louise?"

I knew at that moment it was going to happen and replied, "Yes, if I have your approval?"

David was watching this unfold in front of him, scarcely believing it.

Then I leant in, kissed him, and gently began rubbing the bulge in his crotch. He was hungrily mauling my big tits through my bra and blouse.

"I'm going to fuck him, baby. Are you sure about this?" I asked Robbie.

"God yes, girl," he replied.

I got up and took Davie by the hand and led him to the bedroom. This was really going on.

In the bedroom, I quickly slipped off my trousers, shirt and tights and lay down on the bed in my white lacy panties and lacy bra.

Davie pulled off his shirt and trousers, and boy, was I surprised. His bulge was massive. As he dropped his boxers, his cock stood erect, a massive nine inches long at least and thick.

Davie got down on his knees and buried his face into my panties, nibbling my pussy through my panties. God, it was so erotic.

"Oh God, baby, yes, please take my married cunny," I pleaded.

Out the corner of my eye, I saw Robbie slink into the room and sit in the chair in the corner and take his cock out.

Davie had pulled my panties to the side, and his tongue was probing deep into my soaking pussy as I moaned in pleasure, pulling his head down onto me. I was in ecstasy; this was unbelievable.

"Oh Jesus yes, baby, eat that minge. Take it. It's yours, baby."

I was being licked out as my husband sat and watched and played with himself.

A few weeks ago I would never have thought this possible. As I approached my first orgasm, Davie stopped licking; he really knew how to tease you.

He eased off my panties, unclipped my bra and threw them on the floor. He then began to nibble and gently bite my clit, and sure enough, I burst into orgasmic delight. He then gently eased his cock into my moist pussy and began to grind his massive cock into me as he hungrily sucked my tits.

"Oh please, honey, please fuck me," I sobbed.

As Davie began to quicken his thrusts, I was bucking my hips to meet his thrusts. I was completely gone; this was sex on a new level for me.

I had never been so aroused sexually before. I felt his cock was going to burst me, and I loved it.

With my eyes wide open as Davie began to furiously pump his cock hard into me, I noticed Robbie furiously wanking into my discarded panties. Davie then asked if he could take me doggystyle, and of course I said yes.

My god, if he was fucking me good before, the penetration he got pushing from the rear was intense, and I literally burst into orgasm and collapsed on the bed, but obviously Davie wasn't finished.

He laid me on my back on the bed, lifted my legs over his shoulders and began to furiously pound his big cock deep into me

"Fuck yes, baby, ride me, pump me, Fuckin ride me like the bitch I am," I squealed in pleasure

I was literally crying with joy as another orgasm washed over me, and a few minutes later, as wave after wave of mini orgasms burst within me, I felt Davie stiffen, and a large spurt of semen exploded into me. As he collapsed, spent, on top of me. I could not see Robbie in the room.

God only knows when he left, but I didn't care; I'd just had the best ride of my life.

"My God, Davie, that was amazing," I purred in delight.

Dave snuggled up behind me, his limp cock nudging me as he reached around to feel my tits.

As we lay gently kissing, we both eventually fell into a fitful sleep.

I don't know how long we slept, but I was awoken to feel Davie's cock gently nudging its way into my swollen pussy lips and deep into my crack.

This time it wasn't hard and fast but long, slow strokes filling my pussy and again driving me crazy with anticipation. The long, slow strokes as he fondled my tits, tweaking my erect nipples, had me gasping in pleasure and begging him to please make me cum again.

As he slowly thrust into me, he reached under with one hand and began to rub my swollen clit, and in no time at all I was once again cumming like a train. Wave after wave of orgasms, and then, boom, another thick wad of semen.

This time Davie gently kissed me, thanking me for a fantastic time but admitting he felt really guilty.

I fully understood this as I suddenly felt pangs of guilt engulf me as I heard Robbie snoring in the spare room.

Davie dressed and left with my heartfelt thanks but an overwhelming fear that my life had changed forever.

I fell asleep, my head swimming with confusion. I don't know how long I slept, but I awoke feeling I wasn't alone. It was Robbie.

He gently kissed my forehead and hugged me close. I felt like shit: my head was all over the place, and I could feel Davie's spunk dribbling down my thigh.

Robbie sensed my unease and gently asked if I'd enjoyed the experience. And I replied yes, but I told him I regretted it.

He said no: he had wanted this, and he'd enjoyed what he'd seen. He then began to question me, and as I told him what transpired, I could feel his cock stiffen. He rolled me onto my back and mounted me. As he slid his cock into my wet snatch, I closed my eyes and exclaimed, "Yes, Dave!"
