We both left for work in the city quite early. We worked in different offices - occasionally meeting for lunch. Normally Monday was a day we didn't meet up, but at 10 in the morning Tim called me to say that we should meet becuase he had something to tell me.

I was quite curious as to what it was all about and at lunchtime we met at a local hotel for a light meal and a beer.

"So," I asked when we finally got settled " whats the news?"

"Martin came to see me this morning" Tim began "He told me about his meeting with Kathy on Saturday night."

"Oh yeah... he wasn't looking forward to that was he"

"Well.. it seems his fears were unfounded. Apparantly she spent most of the evening quizzing him about exactly what we did that first night. And then he told her about what we did at the shack. He was expecting her to fly off the handle, but she didn't. He's a bit confused. Anyway the upshot of it all is that she has asked to come round and talk to us about it. I'm not sure why"

I agreed that it all sounded very strange, but i wasn't unhappy at the thought of them coming round. I realised my attraction for Martin was more than just physical and I'd always found Kathy very sexy. We'd only met a couple of times but she seemed like a nice person - it would be such a shame if they did go through with a divorce.

Tim and I agreed that we wouldn't do much in the way of a meal - if she was coming round just to have a go at us we didn't want good food to go to waste.

When I opened it i could hardly believe my eyes - Martin and Kathy looked quite stunning. Martin was standing a little ahead of Kathy and moved quickly to give me a light embrace and a quick peck on the cheek, before turning and introducing Kathy. There was something about him though - he looked like a liitle boy that had just come back from the fun fair. But I didn't have time to figure out what it was - because one look at Kathy made me forget everything. I almost choked - she looked absolutely stunning ! long black hair cascading to her shoulders, framing a face that while not exactly beautiful, yet glowed with beauty, she had on what almost seemed like a miniature poncho! A glittery multi patterned piece of material in various shades of blue and green that hung down the front and back of her body and was linked by two small straps about level with her breasts that leaving the sides of her body open to view, This topped a pair of shorts that seemed to be molded to the contours of her body. The total effect was incredibly sexy ! she was a few inches shorter than me and slighter in build too, but so well proportioned that she gave every impression of lushness !

I was a little taken aback at this - and I still didn't know whether she was here to argue about us leading Martin astray or had something else on the agenda. I merely smiled and invited them both in to the lounge. When he saw her , poor Tim's eyes seemed to have fallen out of their sockets ! Martin, like Tim, had opted for a cool patterned shirt and slacks, but he seemed quite happy to step back and let Kathy make the impression - which she certainly did!

"Can I get you guys a drink" Tim said, trying to sound casual.

"Fabulous, yes please" enthused Kathy "what have you got?" and she sideled upto Tim to see what she could get. Martin took the opportunity to come over to me

"Mel, hi..... look I'm really not sure what she's going to say tonight. We've patched things up but I'm not sure why she wants to be here tonight. "

"Well she looks as hot as hell - all dressed up like that" I replied.

I looked up and almost choked. Kathy was literally fawning over my husband - and he too was flirting outrageously. What the hell was going on? I was about to find out. Kathy turned around and then addressed all three of us. "It's only fair that I tell you all why I wanted to come round this evening - especially you Martin. " She looked a little flustered, but the three of us stayed in our positions, all standing and she decided that was her cue to continue. " Martin - I want to thank you for your honesty the other night when you told me what the three of you have been upto recently"

I think I blushed a little - relieved I think that she seemed to be taking it very well, but a little guilty that I had fucked her husband.

" The actual reason I left Martin three months ago was that I was convinced that he was having an affair with his secretary. When I confronted him about it he of course denied it - and now I know why - he was telling me the truth. When he told me in detail what three of you have been doing recently, two things happened. Firstly, I realised that if he was so open as to tell me that then I believe he was also too honest to lie to me about an affair. Earlier today I asked for Martins forgiveness - and we spent most of the afternoon making up."

I looked up to see it was Martins turn to blush a little. Now I know why he looked like the cat who ate the cream - he'd been geeting snuggly with his wife for the first time in three months!

"Secondly - and Martin, I haven't told you about this - I, um.... " at this point Kathy started to look quite uncomfortable. The bravado was failing her, but she continued breavely: "I didn't realise this until a few hours after Martin left on Saturday night - I'm almost out of my tree wuth excitement thinking about my man fucking a gorgeous creature like you, Melissa. My fantasy for years has been to fuck another man while I watched my husband fuck another girl. And thats why I'm here tonight - I want to live out that fantasy."

It was her turn to blush now - now she had said it and it was out in the open there was a tangible atmosphere in the air. I think all of us were a little startled - including Kathy.

My heart went out to her right then, I knew she was nervous. I was just plain excited - the thought of watching Tim fuck this beautiful creature while I fucked her man was very exciting - but I didn't want to be the first to make a move - to seem to eager to pounce on her husband. I didn't know whether Martin would go and hug her or what - but as it was it was Tim who made the first move.

He moved toward her and without a word he slid his hands around her waist, drew her to him and kissed her, gently, tentatively at first, then more deeply and passionately. Bothe Martin and I just watched, but I think we bothe thought that all the things we had shared with other - it was only fair that Tim made the moves on Kathy. Kathy's automatic reaction had been to raise her arms to encircle his neck, but her eyes darted wildly around the room, seeking out Martin and myself in a slightly panicked attempt to see how we were reacting, then as Tim continued and intensified the kiss, her eyes began to close and her body softened and molded more closely to his body. This was my first time seeing Tim kiss another woman in an obviously passionate and sexy way, and there was just a momentary, fleeting jolt to my system before a curious and entirely delicious heat began to build in my body.

My nipples hardened dramatically and my pussy started to weep juices as I watched Tim's hands begin to caress Kathy's ass cheeks through the thin material of her skirt, then move upwards to stroke her back and the area of naked skin beneath her arms. I glanced over at Martin and he was standing wide eyed and slack jawed staring at the tableau in front of him, his wife in the arms of another man, not struggling to get loose, but molding herself ever closer, returning his passionate kiss with equal and mounting passion. I could see there was a struggle going on inside him, but I knew it was one he had to fight alone, so I made no move towards him, even when he glanced my way with an almost haunted look in his eyes.

Then Tim pulled back slightly and we both got a clear view of the hot, hungry look on Kathy's face and in her eyes, "Lift up your arms" said Tim quietly, and Kathy did as he asked, Tim took hold of the hem of her poncho like top and in one movement lifted it over her head and tossed it aside. What had been fairly certain from the start was now confirmed, Kathy had not bothered with a bra, and there was a whole chorus of sharp gasps as her pert, exciting naked breasts came into view. Not overly large, but high and firm and perfectly formed and topped with delightful almost ruby red nipples that were clearly swollen with excitement. Tim's gasp was one of instant lust and desire as he feasted her eyes on the breasts before him, and he wasted no time in bringing his hands around to cup them gently. Martin's gasp was a little more agonized, as the sight of his wife being seen and touched by another man for the first time challenged all his thoughts and feelings and even his very masculinity, but it was already clear to me that the battle was already won or lost (depending on how you looked at it) because even as he watched Tim caress and fondle Kathy's naked breasts there was a massive bulge in his slacks !! he was incredibly aroused !!

This only increased as Kathy reached out and started to undo the belt on Tim's jeans, pull down the zip - which sounded incredibly loud in the almost perfectly quiet room - and allow his them to fall to the floor where he stepped out of them. Tim himself quickly slid down his boxer shorts and stepped out of them. When he straightened up his massively erect cock sprang into view, bringing a sharp gasp from Kathy also ! she couldn't help herself, her hands reached forward and cupped around his cock and began to stroke him.

My own gasp surprised me most of all, because it was totally unrelated to what Tim was doing to Kathy or Kathy was doing to Tim, even though I'd had a slight dread of how I would react to the sight of Tim with another woman. I gasped at the magnificent beauty of Kathy's breasts ! I was shocked to realise that the sight of them was actually turning me on !! My mind very quickly remembered my own sexual fantasy and I finally twigged that maybe sometimne tonight I would realise it to the full. I was so engrossed in this thought that I almost missed the fact that Martin was moving forward towards Tim and Kathy. I jerked into awareness and took a half step forward myself as if to intervene, but stopped suddenly, knowing this had to be worked out between the three of them, but it was still a surprise when Martin moved round behind Kathy and began to unzip her short skirt and ease it down over her hips, as they dropped to the floor and she stepped out of them, she turned her head sideways and lifted it up and Martin's lips plunged down onto hers, kissing her and tonguing her passionately. Then he pulled away and eased her skimpy panties down over her hips also and she stepped out of those, leaving her completely naked, Tim couldn't take his eyes off her - and neither could I ! - she had the most perfect, firm, ripe body I had ever seen, and she set me on fire ! so I had a good idea of how Tim was feeling right then.

Again Kathy glanced over her shoulders, a small uncertain smile on her face, and Martin reached out to gently caress her cheek, then looking at Tim he grinned and borrowing a line that Tim had used earlier that week said "Well Tim, what are you waiting for, I think my wife wants to be fucked !!",

Tim grinned back, then looked at Kathy, a slightly more serious expression on his face "Do you Kathy? Do you want me to fuck you?", for a moment I could see the fears racing through her and I knew what they were, I'd experienced them the previous weekend, the moment of truth, the crossing of the line from fantasy into reality, the moment you could blow your whole marriage out the window, the moment you had to admit to your husband that you sexually desired another man, that you wanted his cock inside you, that you wanted him to fuck you. Even though he'd helped to undress you for the other man, even though he'd invited the man to have sex with you, the fears were still there. Then I saw her eyes drop to Tim's throbbing cock, and her tongue come out to brush over her dry lips, and I knew the battle was over for her, and I smiled with relief as her whispered words reached me "Yes Tim, I do want you to fuck me !"

As Tim took Kathy into his arms and kissed her deeply, Martin moved away from them and crossed the room to me where he immediately drew me into an almost desperate embrace, kissing me hard and thrusting his tongue deep into my mouth, I could feel his body trembling, and I held him as tightly as I could. Finally his trembling eased and we pulled slightly apart, I looked into his eyes with understanding,

"It will be OK" I said "You were different with me than with Kathy weren't you?" I asked, he nodded, a little puzzled "and Kathy will be different with Tim, so you need to enjoy those differences, not resent them" and I grinned, "That's something Tim taught me after last weekend, because he could see I was wilder with you that I'd ever been with him, and to him that wasn't better or worse, it was just different and that very difference turned him on, do you understand ?"

A slow grin came to his face "I think so" he said "you're preparing me for the fact that Kathy might not be able to hide that she's enjoying being fucked by Tim !"

I laughed, "Well I do, so why wouldn't Kathy? Tim has a fantastic cock and he knows how to use it !" I knew I was really pushing things with that comment, confronting his perception of his own masculinity, but it seemed to work, he grinned widely.

"Yeah, I noticed you enjoyed it on Saturday, and I'm pretty sure Kathy's enjoying it now" he said as a loud squeal came from the couch, and we turned in time to see Tim's cock disappearing into Kathy's pussy !!

We stood with our arms around each other watching them, watching Tim's lips and tongue teasing and exciting Kathy's breasts, watching his hands fondling and caressing her tight ass cheeks and watching his cock slowly disappearing then reappearing from her juicy pussy. Watching Kathy's hands stroke and squeeze Tim's ass, urging him deeper and deeper into her pussy. I knew immediately that Tim had decided that the slam, bam thank you mam approach wasn't appropriate on this occasion, he was giving her a slow sensuous fuck, hesitating slightly before each inward thrust, waiting for her body to react, to lift up almost questing for his cock, before plunging deep inside her. Already her head was rolling from side to side, low moans escaping from her mouth as her body arched to meet his downward thrust, and I found myself getting hot from watching. Oh we'd watched quite a few porno videos over the years, and occasionally got a little turned on by them, but this was the first time I'd see a couple actually having sex in the flesh, so to speak, and it was quite different, more real, more honest, and god yes, infinitely more arousing ! The fact that it was Tim, my own husband, only seemed to add to the arousal ! no sense of jealousy at all, I found myself wanting it to be the best for both of them ! and I understood just how Tim had felt the previous weekend, I found myself wanting to urge them on, and an electric shock ran through me as I realised that I also found myself wanting to join in !

Kathy's voice again broke the silence, "Oh yes, Oh god yes!, that feels so, so good, fuck me, fuck me deep !!" and Tim did, fucking his big cock into her writhing pussy with no hesitations any more and Kathy's cries rose to a crescendo,

"Oh god, you're so tight and so hot!" cried Tim, and spreading her legs even wider he almost lifted her off the couch as his cock rammed, and rammed and rammed into her heaving, bucking body. Then I saw her eyes roll back into the back of her head as her body froze in an arched position for a moment, and I knew she was exploding ! then her body shook and shuddered as I heard Tim cry out "I'm coming. I'm godamn coming !!" and he began to spew his juices into her. I could almost feel his cum shooting into me, I was so turned on, and I realised my hand was deep between my legs, finger fucking my own pussy !! I heard a groan coming from beside me and quickly glanced around to see Martin with his slacks around his ankles and his big, beautiful cock being pumped like crazy !! I'd been so busy watching Tim and Kathy I hadn't even noticed that we'd moved apart !! He must have sensed the movement of my head because he half turned, a look of raw lust on his face, and we both realised that we wanted more than our own hands in action !! immediately I started to almost rip the clothes from my body, and Martin did the same, and in seconds we were naked ! I cast a quick glance over to the couch and saw that Tim and Kathy were just coming to the end of their lovemaking, and a sudden , wild idea flashed into my head, so grabbing Martin by the hand I led him over to the couch and knelt on the floor beside it, almost on a level with Tim and Kathy's faces, in fact I was staring deep into Kathy's eyes as I said "Yes Martin, take me from behind, fuck your big cock deep in my hot pussy, fuck me like Tim just fucked Kathy, fuck me hard, fuck me deep!!", then to everyone's shock I lowered my head and wrapped my lips around Kathys right nipple, sucking it hard into my mouth and making her jump!! I heard Martin's startled gasp, then felt his big cock literally hammer into my juiced up pussy "Yes, suck her hot titties while I fuck your hot pussy !!" he almost yelled out, and slammed his cock harder and deeper !! I'd never so much as touched a woman before, and here I was sucking Kathy's nipple and licking her breasts and loving every minute of it! My own girlish fantasy was now being lived out!

After a moment of frozen shock, Kathy's body started to respond to my lashing tongue, and Tim began to respond to the sight of it all, his cock stiffening and swelling inside Kathy's pussy. Martin's hands were gripping and fondling my breasts as his cock reamed into my pussy like a super hot piston, then I felt one of his hands pushed aside and another hand take it's place - Kathy's hand ! and another bolt of electricity ran through me, different and yet incredibly powerful !! Immediately I lifted from her breasts and again looked her directly in her eyes "Mmmm, that feels so good ! so very, very good !" I said, and a huge smile came to her face "Don't stop !" she almost pleaded, "Don't stop !, suck my nipples, lick my titties, you're making me so, so hot !!"

So I did as she asked, and went back to her fantastic firm breasts and licked and sucked like crazy as Martin fucked my pussy and Tim fucked Kathy's pussy and Kathy fondled and squeezed my breasts and nipples ! I don't know who was the first to explode, but it seemed to set off a chain reaction that had all of us howling and screaming as incredible orgasms ripped through us !!

Yet one more step on the path to Sluthood. I was becoming slowly more addicted to sex - and I loved every minute of it.
