I sit on the plane from San Francisco to Chicago thinking about what I have done. I have cheated on my husband Chris for the first time. My first night with my lover Alex felt revolutionary. When he returned to my hotel room again the next night it felt natural. As he pounded into me with his hard cock I thought, "This is what conferences are for. This is what my body needs. What my heart needs."

I know Chris will be waiting to pick me up at the airport. Will I be able to look him in the eye? Will I be able to keep something like this a secret?

As soon as I lay eyes on him, I know that the answer to both of these questions is yes. My sense of liberation and empowerment easily overwhelms any shreds of guilt. I climb into the car cloaked with the quiet thrill of the forbidden.

"I met an old friend of yours - Alex Hansen. He says hello." I try to hide the smirk I feel.

"Ah yes, Alex - wow - I haven't seen him in years. How is he doing?"

My mind flashes to Alex's hard cock deep down my throat. "He's impressive. Very prolific. He gave a great talk."

As the weeks pass I feel energized and cheerful to the point of exuberance. Chris has noticed, but he's not sure what to make of it. My new energy is charged with a sensuality that has increased our intimacy, though he still can't get it up enough to fuck me properly.

Tonight I am lying in bed, too restless to sleep. Chris lies beside me, his slow, steady breathing betraying his deep slumber. I feel a heat building between my legs. But I am not thinking about Alex. I'm thinking about my next trip. Next week. Greg will be there.

My hand slides down to quell my aching desire. My body shivers as my fingers probe my wet, sensitive folds. I can see Greg's lean, rugged face. His intense brown eyes fixed on me as he breathes my name. I resist the urge to move my hips because I don't want to wake Chris. My movements are measured and discreet but relentless. I savor the slow, sensual, build-up to an exquisite crescendo. I catch my breath and close my eyes as the warmth of my release spreads under the sheets.

Greg is a colleague that I have known for years. He is a Professor at the University of Wisconsin - not far from my home in Chicago. He is in his late forties and strikingly good-looking: dark hair, brown eyes, full lips, a chiseled jawline, broad shoulders. A look and an attitude that exudes strength and confidence. He is also brilliant, with a sharp wit and a quirky sense of humor.

Greg and I have flirted before but it never went far because we are both married. That's not going to stop me this time. Last week I bought a form-hugging navy mini-dress to help carry out my intended seduction. I also bought a black lace babydoll with the hope that I will have the opportunity to show it off.

Four days later I am on a plane again, bound for Italy. The plane touches down in Florence - the city of love. One of them, anyway. I make my way to the hotel and check in. Feeling the jet lag, I turn in early.

I first see Greg at the conference the next morning. Our eyes meet in a silent greeting across the room during the presentations. I track him down later at the coffee break.

"Greg - so good to see you again. You look well." That's an understatement.

"Hi Abby. You look great as well. How's Chris?"

"He's good. Working at Lockheed now. He probably works too hard, like all of us. By the time he gets home he's exhausted." Unsatisfying. Did I say that last part out loud?

After politely inquiring about his wife Sandra, I waste no time in pushing my agenda. I brush my hair back and lick my lips. "I have been thinking about the last time I saw you. In Boston. We stayed at that little pub after the others had left."

"Yes, that was a great night."

"You were so witty, and charming." I shoot him a sultry gaze and brush his arm with my hand. "I regret turning in early."

"Well, it was probably for the best." His response puzzles me. Something seems off. He is not picking up on my advances the way I had hoped.

I up the ante. "Are you free for dinner tonight? Just the two of us?"

"I'd love to, but I have plans. We should definitely get together later this week, though." He abruptly excuses himself to talk to another colleague. "Sorry - I want to catch Matt before the session starts. It's good to see you. I look forward to catching up later."

I look down, defeated and confused. It's only then that I notice the looming presence that had been behind Greg during our entire conversation. A young woman, petite and attractive. Asian-American, by my guess. She approaches me with a smug smile.

"You want to fuck him, don't you?" the woman says with a tone that is bold and accusing, as if she has caught me in an illicit transgression - which, of course, she has. But there is a playful glint in her eye. And do I detect a hint of admiration?

"Excuse me?" I should be offended by her rudeness but she can see by my reaction that her blunt assessment was right on target.

"Oh my God - you do, don't you? Aren't you, like, married?" She is mocking me with her laugh. I should be angry but I find myself captivated and strangely aroused. The subversive mirth of her thin red lips. The intoxicating sexual energy in her narrow brown eyes. The gentle curve of her collarbone gracing her softly heaving chest.

"Do I know you?"

"I'm Chloe. Chloe Kimura. It is an honor to meet you, Professor Stone. Of course, I know you by reputation." She extends her hand to shake mine, but I do not reciprocate, still reeling from her crude greeting. I'm still trying to figure out how I should react.

"I work with Greg. He hired me last year. I think I have become his most valued collaborator." As she gazes at me with raised eyebrows and a provocative grin, it suddenly hits me. Greg is fucking her.

"Is that so?" I suddenly want to be somewhere else. But Chloe's demeanor warms. She leans in closer, as if to reveal a secret.

"I am Greg's plans for tonight, in case you were wondering." Her supple lips approach my ear. Her voice drops to a whisper. "Come to room 611 tonight at 9pm. You'll get what you want and more."

My eyes follow her as she turns to go. Her skirt hugs her slim figure. Her pixie haircut highlights her delicate neck. I find myself speechless. This is definitely not according to plan. I return to the lecture hall for the remaining morning presentations but I don't hear a word. I'm grateful for the opportunity to sit and collect my racing thoughts without having to interact with anyone.

What exactly is she saying? That she wants me to join them? Like a threesome? I am aware of the concept, of course, but I have never engaged in a menage a trois. Do they even call it that anymore? Here I thought I would seduce Greg into cheating on his wife but it turns out Chloe beat me to it. Now am I attracted to Chloe? What the fuck is that all about?

By the afternoon coffee break, my mind is still a blur of confusion and arousal. I see Chloe approaching me and my heart skips a beat. She whispers something in confidence as she passes.

"I told Greg you'll be joining us tonight. He's all in."

There is no longer any doubt about what will happen if I go to room 611 at 8pm. I will have Greg, yes, like I wanted all along. But I will share him with Chloe. Will Greg share me with Chloe? My God, I have never been with a woman. But the more I think about it, the more I think there is no woman I would rather be with than Chloe.

She is gorgeous, with a slim, alluring body. Short black hair with wispy bangs running down past her eyebrows. Subtle eyeliner that is discreet enough for a professional conference but bewitching enough to consume you if you look more closely. Her playfully rebellious attitude enchants everyone she meets. The way she moves - the way she speaks. I have never met anyone before who radiates so much sexuality. A consummate tease. God, I bet she is an exquisite lover. No wonder Greg is fucking her - I don't blame him.

When the meeting ends I retreat to my hotel room. I cannot face my scientific colleagues in my hot and bothered state. I order room service for dinner. As I eat, I cannot shake the mental image of Chloe riding Greg, her lithe body gracefully undulating as Greg's hard cock slides in and out.

It's 8 o'clock. I have to make a decision. Am I going or not? Maybe I can take a shower just in case. I resist the urge to touch myself in the shower. Gratification will come later, if this night proceeds the way I suspect it will.

I put my new dress on over my favorite lace bra and panties. It's a shame that I can't show the dress off in public yet but Greg will see it at least. And, um, Chloe. I breathe in deeply to calm my nerves. I probably don't need much makeup but let's have red lips, at least.

It's 8:55. I look at myself imploringly in the mirror. Now or never. I think of my husband Chris. Then I remember my vow in San Francisco to not be shackled by his impotence. Is this the new me or isn't it? I decide that it is.

Having already engaged in the soul-searching, I find room 611 and knock on the door with confidence. Chloe answers wearing one of the terry cloth bathrobes that comes with the room. My eyes drift down to admire her toned legs as I follow her in.

Greg is sitting in a chair in the corner. He is wearing the other hotel bathrobe, suggesting that they have already had a round before I arrived. He smiles at me sheepishly. "So, Abby, you know my secret."

I look at him without judgement. "How long has this been going on?"

"Only a few months. Chloe joined the team almost a year ago but we didn't start a relationship right away."

"I knew he couldn't resist me for long," Chloe chimes in.

"Does Sandra know?" I know this is a silly question as soon as it leaves my mouth.

"Of course not. We have been meeting discreetly, mostly at Chloe's apartment. But it's not easy to get away from the family."

"I fucked him once in his marital bed when Sandra and the kids were out of town," Chloe adds triumphantly.

"We have been looking forward to this trip as an opportunity to spend more quality time together," Greg continues.

"Then why am I here?" I begin to question my recent life choices.

Chloe stands and removes her belt so her robe hangs freely around her shoulders, offering tantalizing glimpses of her nude body beneath. She approaches me and caresses my arm. Her face moves inches from mine. "Because you want to be here, Professor Stone. Admit it."

Chloe has rendered me speechless once again but she proceeds undeterred. I do not resist as her soft lips pepper kisses on my neck and her hands roam over my body, feeling my curves through the fabric of my tight dress. Her hand reaches under my dress and up my thigh as she speaks again.

"Have you ever made love to a woman, Professor Stone?" Chloe's repeated use of my formal title is a deliberate move to expose the hidden depravity behind my distinguished professional facade. It is clear that Chloe likes to take control.

"No..." I breathe as her fingers reach the heat of my panties. I lean against the wall as she hikes up my dress. Her lips crush into mine as she simultaneously thrusts her hand under my panties to stroke my increasingly wet labia.

"Oh fuck...yes..." I manage to say at the first break in our kiss.

"Do you want me to eat your pussy, Professor Stone?" Chloe says as her dexterous fingers skillfully circle my clit.

"Yes, please...God..." Her fingers and mouth are sending waves of pleasure through me unlike anything I have ever experienced.

"Please what? Say it."

"Please eat my pussy Chloe, oh God..." The rapture of her touch is almost unbearable.

"Take off your dress and get on the bed," Chloe demands. I have never been submissive with my husband but I find myself obeying Chloe without question.

"She can be pretty convincing," Greg muses as he rises and removes his robe, revealing his semi-hard cock.

I look over at Greg with an expression of lustful surprise. I had been so focused on Chloe I had almost forgotten he was there. I stare at his quickly hardening cock with fascination as Chloe removes my panties. This is what I have been dreaming about for weeks - maybe years. It's perfect. Better than I dared to imagine. Hard and thick with a slight upward curvature.

My thoughts are suddenly interrupted by the warmth of Chloe's mouth on my achingly wet pussy. She digs in with the enthusiasm and prowess of a porn star. My hand lovingly runs through her jet black hair as I press her head closer. My body is shivering with pleasure as I feel Greg's strong hands pull me to the edge of the bed.

I lie on my back with my head hanging over the edge of the bed as Chloe continues to ravish me. I feel something press against my lips and I open my eyes to find Greg's hard cock. I instinctively part my lips as he slides his cock down my throat. He squeezes my tits as he fucks my face, his balls slapping against my nose.

I feel more dirty than I ever have in my life and it feels exhilarating. What would Chris say if he could see his wife now? Sucking a colleague's dick upside down while getting eaten out by his female postdoc? The sensation and the scenario overwhelm me. My body shudders with the most intense orgasm I can remember.

As I recover, we switch positions. I am still on my back, with Chloe on top of me. She straddles me as our breasts come together with sensual friction. She kisses me deeply as Greg enters her from behind. He pounds her hard. It is clear they have done this before, but now I am witnessing it from below. Each of Greg's thrusts presses Chloe's soft, lithe body hard into mine. Chloe's lips meet mine with surprising gentleness, in spite of the forceful impacts her petite body is absorbing from behind.

After some time, Greg pulls out of Chloe with the clear intention of experiencing me before he gives up his load. He guides his cock to my opening and gently, almost reverently slides it in.

"God, Abby, I have wanted to do this for so long," he says as he steadily picks up the pace.

"So have I, Greg - more than you can imagine."

Meanwhile, Chloe has turned around and positioned herself directly over my head, straddling my face. Her pussy hangs over me invitingly, and I extend my tongue to taste a woman for the first time. So much sweeter than I ever expected, though I haven't really thought about it enough to expect anything. I grab her tight ass and probe deeper with my tongue as Greg increases his pace.

"That's it, Professor Stone," Chloe teases as she slowly grinds her hips on my face. "I'm going to be thinking of your tongue inside me when you give your presentation on Wednesday." She leans forward to kiss Greg deeply.

I feel Greg's cock twitch inside me. I can sense that he is close. I gasp as I feel his hot cum suddenly coursing deep inside me. He lets out a primal groan. His orgasm triggers my own - is that number two or three? I've lost count.

After Greg and I are spent, we owe it to Chloe to get her off too. She lies on her back and spreads her legs. Greg dutifully devours her pussy while I caress and suck her perfectly pert breasts. It is as if we are serving our benefactor in appreciation for making this unforgettable rendezvous happen. Soon there is a loud moan, accompanied by muscle spasms and a profound release that mark Chloe's climax.

The three of us collapse on to the bed, exhausted but satisfied. A few moments pass in silence as we catch our breath and try to process what just happened.

"I think that was the hottest sex I've ever had," I confess as I look blankly up at the ceiling.

"Well, we're here all week, in romantic Italy." Chloe smiles. "Surely we can top our first night. Challenge accepted."

"How does Greg keep up with her?" I wonder silently to myself. But I have to admit that I'm excited to see what happens next.

Reality soon sets in as I remember that we have a conference to go to in the morning.

"I should get some sleep. I'm still feeling a little jet lagged and we have a busy day tomorrow."

"Of course, Professor Stone," Chloe says in her most obnoxiously satirical tone. "We'll see you bright and early at the presentations. Don't forget your notebook."

I smile, gather my clothes, and slip out the door, knowing that this won't be the last time this week I'll see them. I make my way to my own hotel room.

When my head finally hits the pillow, I find myself dreaming of Chloe rather than Greg. After all that time I spent planning and anticipating my grand seduction of Greg, it was Chloe who captured my heart, along with a few other body parts.

I drift off to sleep, pondering the wry twists of fate and the irresistible pull of desire.
