Michael stood and tugged his swim trunks up from around his ankles.  Ali exited the cabana carefully, parting the curtains slightly and peeking out to make sure that no one was around to notice.  When she was satisfied that the coast was clear, she parted them and walked out.  Michael paused briefly and followed. 

As Ali turned the corner, he saw her glance back over her shoulder and give him a seductive smile.  As his eyes traveled down her magnificent back, around her youthful ass, and down her toned, tanned legs, he noticed a trickle of white fluid, barely visible but clearly traveling down the inside of her right thigh.  His softened cock began to stir, and he shook himself back to reality, returning to his chaise to gather his things and head to the room and Amy.

As he walked through the lower lobby toward the elevators, he was keenly observant of the people he passed, particularly the attractive women.  They came in all age and appearance categories, but he noticed that many had a healthy glow about them.  No doubt the sun and relaxing atmosphere of this beautiful resort had much to do with that, but his naughty mind said that sex also played a role. 

Perhaps that was because today had been such an amazing and unusual day for him.  This place had worked magic in his life in the form of an alluring and erotic young woman who had milked him for all he was worth.  He must have been giving off that glow himself, because several attractive women locked eyes with him and smiled as he passed.  He wondered how many had just impaled themselves on a lover, and whether it was their partner or a handsome stranger.  If it had happened to him, it could have happened to them as well.  This wasn’t that kind of resort, but paradise does have a way of casting its spell.

Michael began to reflect on the events of the day, specifically his breaking of his marital vows.  It was clear to him that, given the right circumstance, he and Ali would become intimate again, as many times as possible during their time together here.  Was Ali a one-time fling, he wondered, an accident of opportunity, setting, and extraordinary chemistry.  Was this merely a very unique and special episode in an otherwise conventional life, something to be locked up and kept in the vault of his memory and his heart?  Or had Ali awakened something in Michael?  Had she unlocked a cheater, and once that door was open, was there any turning back?

Certainly, Michael had no delusions that opportunities like this would be readily available, particularly ones involving such an alluring, sexy, and young woman.  But he also noticed the smiles of the women he passed.  Could they tell? 

He tried to feel guilty but couldn’t.  That much alone was likely telling.  He had fucked Ali in the room in the late morning and sinned again with her a mere few hours later.  At the same time, his love for Amy was undiminished.  In fact, he couldn’t wait to make love to her this evening.  Ali had unleashed a more sexual Michael, one who was attuned and aware of the beauty and sensuality of all women, most especially Amy.

Where this would go from here, he decided, would depend on how he felt when he returned to the room to Amy; whether he could compartmentalize what he had done, and was likely to do again with Ali.  He walked down the hall toward the room, tapped the key and opened the door to find Amy in the sitting area wearing a bathrobe.

“Sorry, I hope I’m not running too late,” Michael said as he walked into the room.  “I kinda lost track of time a little bit.”

“I know.  Who is she?” came the reply.

Michael stopped dead in his tracks.  “What are you talking about?”  He tried to remain outwardly calm, but inside his heart was pounding and his brain swimming.

“Michael, don’t play coy with me.  I saw you.”

“Saw what?”

“Michael, please sit down.”  He did as he was told, and Amy continued.  “I realized I’d left my phone on the table with your things.  I turned around to come back and get it, and as I approached I saw a very attractive young lady talking to you.  I was curious, so I hid behind some plantings to watch.  At first, I thought it was innocent, but then I saw her sit down on your chaise.  I saw her run her fingernails across your thigh.  Then she took your hand and stood.  I was shocked.  My heart began to pound when I saw you follow her to the cabanas.”

Michael was paralyzed.  Never in a million years had the possibility of being discovered crossed his mind.  He was at a loss for words.  The silence in the air was deafening, the tension thick.

“So, who is she?  I want to know everything.  And I mean everything.”

An awkward silence followed while Michael considered his response.  Finally, “She’s nobody.  Just some girl I met.”

“She’s not just some girl, Michael.”  Amy’s voice was resolute, but surprisingly lacking in anger.  “She has a name.  Let’s start there.”

“It’s Alison,” he replied.  “Ali, actually.”

“Ali.  That’s cute.  She’s cute.  Adorably sexy.”  Michael couldn’t read her tone.  Was it sarcastic, playful, mocking?”

Another awkward silence filled the space.  Michael noticed a glass of wine on the table next to her chari.  Amy reached over, took a drink, and continued.  “You fooled around with her, obviously.  No one goes to hide in a cabana just to talk.  I want to hear it all.  From the beginning.  Every detail.  Tell me how you met.”

Michael slowly began to describe running into Ali when looking for a spot to lay out at the pool, her invitation to sit next to her, their conversation turning more intimate, and, finally, her proposition.

Amy interrupted him.  “You want me to believe that she came on to you?”

Michael looked her directly in the eyes, and, holding her gaze, said “that’s what happened.  She made the first move.  I was very turned on by the time she did, but never even thought of the possibility.”

“And so where did you go?”

Michael let the silence fall once again.

“You didn’t bring her here…?”

Michael could only nod his head, his eyes cast downward.

Amy rose from her chair and walked over to the foot of the bed.  She patted it with one hand and looked at him.  “So, you fucked her in this bed?”

“Yes.”

“Our bed?”

Another nod, eyes once again cast downward.

“Where you fucked me last night?” 

She let the question hang in the air through the awkward silence that followed and walked over to her suitcase to retrieve something.  She returned to her chair and sat facing him, opening her robe and splaying her legs out slightly.  The hum of her bullet vibrator broke the silence, and she began to run it across her erect nipples.

“Was it tender? Romantic?  Rough?”

No response.

“Did you kiss her?”

“Yes, we kissed.”

“A lot?”

“Yes.”  Michael realized this was turning Ali on.  Gradually, his inhibitions began to fall away.  He would give her what she wanted.  “Passionately.  She made these adorable little moans.”

The vibrator moved down Amy’s belly.  Michael could see that the lips of her cunt were swollen.  A musky aroma was faintly noticeable.

“She sucked your cock first, didn’t she?  Like a good little slut?”

“She dropped to her knees quickly.”

“How hard were you?” she asked.

“Rock hard.”

“Precum?”

“Yes, lots.”

The bullet hit her clit, and she arched her back.  Her face scrunched, the expression of arousal so familiar to him.  “And could she deep throat?”

“I shoved it all the way down.  Balls deep.  She didn’t gag,” he replied.

“There was saliva on the rug then.”

“Yes, drooling from her mouth.  I also ordered her to spit on it and jerk me off.”

A sharp intake of breath emitted from Amy.  “But you didn’t cum yet, did you?”

“No.”

“You wanted to fuck her.”

“I did want to fuck her.”

“There are no condoms here.  I presume she didn’t bring any?”

Michael responded with a simple “no.  No condom.”

Amy looked directly at Michael.  “Tell me exactly what you were thinking, what you were feeling, when your hard, raw, bare, precum-dripping cock was poised at her entrance.  At the moment that you were about to truly, fully, irrevocably break your marriage vow.  Just before your ultimate act of betrayal.  Did you think about me, about your poor innocent little wife down there in the spa, completely clueless?”

Michael’s response was immediate and direct.  “I had thought about you down at the pool, when she first suggested we come up here, but I pushed it out of my mind.  From there, I was consumed by pure lust.  Just before I entered her, I paused.  I realized this was wrong, but also so right.  I can’t deny that.  I looked down at my cock, harder than you can imagine, and her tiny little bald pussy, her lips swollen and moist.  She pleaded with me to stop teasing and fuck her, and I thrust it into her as hard as I could.”

Amy groaned as the bullet hit her clit again.  She swung her legs over the arms of the chair. 

Michael’s cock had sprung to life as he told the story and replayed the events once again.  The bulge in his trunks was evident.  Amy looked at it and moaned, “take off your shorts and sit back down.  I want to see that cheating cock.”

Michael removed his trunks and shirt and sat back down.  Amy’s robe was completely open now, and she was working the bullet across her vulva and clit.  At her prompting, Michael described in detail the feeling of her tight, college pussy on his cock, the desperation in her voice as she begged, the stream of filth that poured out from their mouths.

“How much tighter is she?  How much smoother?  How much tauter is her little body?”

Michael himself was groaning as he retold the details.  The positions.  The spanking, choking, spitting.  How he became a crazed fuck animal.

“Where did you cum?”

Michael described the buildup in his balls.  How they were boiling to the point of explosion.  How the sight of her body below him, and even more, the dirty, nasty, forbidden, secret adultery, pushed him over the edge.  How he never considered pulling out.  How he needed to empty himself deep inside this young concubine.  How she screamed out in delight and ecstasy as he pumped spurt after spurt of his fluid into her willing body.  How he almost blacked out.

How she wrapped her legs tightly around him to pull him deeper.  How she kissed him with the fervor of a young woman possessed.

At this, Amy exploded.  Her screams echoed off the walls and ceiling of the room and her cum sprayed out onto the carpet.  Her orgasm raged on, squirt after squirt, her entire body convulsing.  Her cries continued, less intense but no less desperate as she released all of the tension that had been building up since she saw her husband steal away with his new concubine.

Michael was transfixed, and could only watch in wonder as Amy slowly came down from her orgasm, her legs still trembling uncontrollably and her eyes rolling back in her head.  He gazed upon his wife and never had she looked so beautiful, so sexy, so sensual.  His cock felt like it would burst.  He desperately needed to cum, but didn’t dare make a move.

Amy finally collected herself, returned her gaze to her husband, and stood up.  She walked toward him and knelt in front of his chair.  She gently touched his cock and looked up into his eyes.  “You fucked her again just now.  Did you swim afterward?”

“No,” he replied.  “I came straight up here.  I thought I would go directly into the shower.”

“So she is still on you,” Amy responded,  as she flicked her tongue lightly across the underside of his shaft.  She flicked her tongue again and licked her lips.  “Mmmmm, I can taste her.  Both of you.”

Michael expected her to go down on him and clean him with her mouth, but she had other ideas.  Standing up, she pushed him down in his chair and straddled him.

“I need to feel her inside me.”  And with that, she lowered herself onto him. 

"Fuuuuuccccckkkkkk!” she cried out as his cock, crusted with the dried cum of his adulterous tryst with Ali, slowly filled her pussy.  Amy paused as she bottomed out on him and then began to fuck Michael, her hips moving up and down and his shaft sliding in and almost all the way out of him.  She began slowly and then began to pick up the pace.

“Did she ride you like this,” she asked.  “How did it feel?”

Michael looked at her.  “Do you really want to know?  It felt amazing!  She was so hot, wet, and tight.  Young.  And not my wife.”

At that, he rolled her over, taking charge and pounding her mercilessly.  Amy’s body was convulsing, her breasts heaving, her nipples engorged and erect.  Michael pulled out and moved her aggressively up onto all fours, spanking her twice before slamming back into her. 

Amy thought his cock would penetrate through her belly and into her throat, he was fucking her so hard.  She could hardly concentrate enough to grunt the words in her mind.  “Fuck me, Michael.  Fuck me like you fucked her.  Harder!  Don’t hold back!”

A switch was flipped inside Michael.  He grabbed a fistful of Amy’s hair near the base and pulled back sharply, exposing her vulnerable neck, and leaned down close, whispering in her ear.  “Like this?”

On each violent thrust of his cock, a single grunted word in response.  “Oh!  God!  Fuck!  Yes!”

Michael’s hips smacked roughly against the back of Amy’s thighs, and he reached back with his free hand and spanked her ass cheek hard.  Amy could only grunt some more, finally finding enough breath to cry out.

“Fuck me like I’m Ali, you dirty fucking bastard!”

The words were too much for Michael.  He gazed down.  Here below him was his wife, the love of his life.  Her back curved gracefully into her round, still firm ass.  Her skin was flushed red and covered with a light sheen of sweat.  Her grunts mixed with groans and she let loose with another scream as she collapsed below him in spasms of uncontrollable release.  He didn’t stop, continuing to ram into her now prone body.  He pushed her legs together, causing her pussy to grip him even more tightly and allowing him another few millimeters of depth into her cavern.  He pushed her head down as he felt his orgasm building.

Amy could feel his cock swelling and knew what was near.  She cried out again.

“Cum in me.  Cum in me!  Cum…. In….. Me!”

Michael ejaculated for the fourth time that day, and the length and intensity of his release surprised and frightened him.  Jet after jet of semen shot forth from his cock and coated the insides of Amy’s cunt.

The first spurt hit her cervix with a brutal force, and Amy exploded, uttering a string of filthy obscenities and screaming to the heavens.  Her orgasm went on and on and on, and her hands grabbed for the sheets, anything, to control her body’s thrashing.  

Amy moved forward, causing Michael’s still erect cock to slide out of her, accompanied by a dollop of cum.  She spun around, took ahold of his cock, and began to clean it thoroughly, licking up and down the shaft with her tongue and then taking it all the way into her mouth.  When she was satisfied, she rose onto her knees, grabbed his face, and kissed him deeply.  As their mouths joined and their tongues danced, Michael could taste Amy’s and his own cum, seasoned gently with the remnants of Ali’s juices that had dried on his cock from the cabana.  Breaking the kiss, she looked him deeply in the eyes.

“I want to see you fuck her.”

Michael was speechless.  He could only look at her quizzically.

“I want you to bring her here and fuck her.  I want to watch.”  Her tone was determined, resolute, definitive.

“I will have to find her first.  I don’t have her number or her room.  That probably won’t be until tomorrow.”

“That will have to do, then,” Amy responded.  She stood and walked to the bathroom.  Michael watched as her naked ass swayed seductively.  His cock twitched again in response to the sexy vision walking away from him.

Amy reached the bathroom door and looked over her shoulder.

“Better get moving.  Dinner awaits, and I’m starving.”
