It all started on the train on his way home from the office.  His cellphone buzzed, and John saw that he had a picture message from Aileen.  In three years of marriage, it was the first time she'd ever sent him a nude picture of herself.  Lying on her back, on top of her blue yoga mat, a naked selfie.  He felt himself getting hard.

"Got company?" he replied.

"No"

"You mean not yet?"

"What if I do?"

"Then take pictures so I can watch"

"Yeah right"

"Serious.  If you fuck someone else I want to see it"

"Think you can handle it?"

He felt his heart beating faster.  He was excited now, starting to sweat, and fully erect.  Could he handle it?

"I can," he replied, "can you?"

"We'll see"

"Then show me"

"Whatever"

He'd never driven home so fast.  He found her still in her exercise room in a tank top and yoga pants.  Fifteen seconds later she was naked and they were fucking on the blue yoga mat.  He didn't bother asking until after, if she had or expected company.  He was surprised to feel disappointed that she didn't.  That she was just teasing him.

As the days and weeks passed they went on with their normal, quiet lives.  Neither again brought up the idea of adding another player into their sex life.  John, however, hadn't forgotten about that train ride home.  He'd had dreams about it.  About watching Aileen with another man, and other men.

- - - - - - - - - -

The sound of the doorbell startled her a bit.  She was anxious, but unsure if she could follow through with her plan.  She'd made the date as an impulse.  Angry at John after a heated argument, she suddenly remembered the day she sent him the picture.  THAT picture.  He'd given her permission, hadn't he?  Even dared her to do it!  Why not then?

After John left to cool off, she picked up her phone and texted a coworker.  Chris, the IT guy who'd always flirted with her.  He'd said, in passing, that he had a weakness for Asian girls.  Let's see how weak.  He asked her why she hasn't been at work, said he'd missed talking to her at lunch.  She explained she had some family issues and she'd be back soon.  After a short exchange she made her move.

"Can you get the day off tomorrow?" she asked.

"Probably.  I have a lot of PTO.  Why?"

"I'm having some computer trouble.  I'll buy you lunch if you help me out.  : )"

Lord, how cheesy, she thought.  Like he would really take time off work to do free work.  What a stupid-

"Deal!  What time?"

"How about noon?" she tapped as fast she could, before she lost her nerve.

"Sounds good! See you tomorrow then!"

"Okay. See you then"

She couldn't believe she did it!  She felt like she was in high school again.  John would be gone from 6 am to 4 pm.  Plenty of time to... to what?  She knew what she wanted to do, but what about Chris?  Then it crept up on her.  The idea that she would be seducing another man in her and her husband's home.  She liked it.

She took a long look through the peephole to give herself another chance to back out.  Instead, she was reminded why she chose to text him of all people.  She opened the door with a smile, which he returned.

"Hey!" he said.

"Come in," she replied with a smile.

As he walked past her into the entryway, she could tell by his glance that she'd picked the right outfit.

"Sorry, I was just working out."

"It's fine," he laughed back.

She was wearing her loose-fitting running shorts.  The ones that were too short to wear out in public.  The ones that always got a rise out of John.  She usually wore a t-shirt to work out, but John always suggested she just wear a sports bra.  Looking at Chris' face, she now knew the reason for that request.

"Damn, I didn't know you had a pool table," John exclaimed.  "Are you good?"

"I'm okay."

"Yeah, right.  Just okay?"

"You want to play?"

"Yeah, I do!  But I should check out your computer first."

"Oh yeah, sorry about that.  It fixed itself."

"Really?"

"Yeah, I was having a problem with my email, but it's fine now."

"I saw that Windows had an update last night.  That probably fixed it."

"I guess.  I still owe you a lunch for coming all the way out here though."

"Nah, it's fine."

"Nope.  A deal's a deal.  How about after we play?" She flashed him a coy smile.

"Ok," he laughed, not yet catching her meaning.

- - - - - - - - - -

John was walking back to the office when he felt the buzzing in his pocket.  He swapped the bag of fast food to the other hand and pulled out his cellphone to find a text from Aileen.  His heart sank when he saw the picture message, Aileen's face with another man's cock pressed to her lips.  A few seconds later the question arrived.

"Still want to watch?"

- -

Aileen grabbed the diamond and racked up for a game of nine-ball.  Chris stared from the other side as she leaned over the table to set the wooden rack into position.  The cut of her top was just low enough to get a teasing hint of cleavage.

"You can break," she smiled.

"Okay," he replied, obviously nervous.

She grabbed her cue and leaned back against the wall across the table from him.  She watched him switch focus a dozen times between the cueball and her body.  It was an old trick she'd picked up from John, to distract the other player.  As he drew back to shoot, she moved the cue in front of her, between her legs, and slowly slid her hands down the shaft.  She held back a laugh as he struck the cueball off-center and watched the tight formation of balls became a loose cluster.

"One ball, corner pocket," she said as she rounded the table.

Aileen bent over the side bumper, rising onto her tiptoes, and stretched out across the full width of the table.  As she did, Chris watched her top rise just enough to expose a hint of the bottom of her breasts.  He didn't even notice when she made the shot.

As she ran the table on him, Chris began to get the impression she was also toying with him.  The innocent way she called each shot.  The triumphant smirk she'd flash him after every successful pocket.  The exaggerated arch in her back as she bent over the table.  Was she really trying to seduce him?  Just then, as she bent over to line up a play on the nine-ball, directly in front of him, he was sure.  As she adjusted her position and made the shot, the looseness of her shorts betrayed the fact that she was not wearing panties.  In that moment, staring at her glistening, wet pussy, Chris knew why he was there.

"Close game!" she laughed.

He walked around the table and began racking up for another round.

"Yeah, but I'll get you this time," he said with confidence.

"I can't wait!" she countered with a grin.

He watched her as she chalked up her cue, and imagined what he'd do to her.  Even better, what she'd do to him.  He was rock hard now, beginning to sweat.  Finally, she walked back to the front and placed the cueball on the table.  Just as she leaned forward to line up to break, he stepped up behind her, leaving her only a few inches of space.

"Excuuuuuse me?" she said, feigning disapproval.

He stood motionless, arms crossed, wearing his own mischievous grin now.  Your move, he thought.  He was not prepared for what came next.

Aileen laid the cue on the table, grabbed the bumper with both hands, and bent over in place, resting her face between them.  She then pushed back hard, slamming her pussy into his crotch. Even through his jeans he could feel the shaft of his cock slip between her labia as she rocked her ass from side to side.  One hand grabbed her waist as the other urgently undid his pants.  He'd just begun to press the tip into her soaking wet pussy when she stood up, turned around, and grabbed it firmly in one hand.

She gave it a tug and led him over to the leather sofa across the room.  She reached down with her free hand and picked a cellphone up off the coffee table, then sat on the couch to face him.  She looked up to meet his gaze, licked her lips, and snapped a picture as she pressed them against his cock.

- - - - - - - - - -

John was furious.  Immediately his mind went to the fight they'd had the day before.  But that was resolved, wasn't it?  They'd more than made up that night.  So why was she doing this?

"WTF," he smashed into his cellphone, "WHO IS THAT"

It was the only thing he could think to say.  He was almost running now, trying to get back to the office to- do what?  He realized he was an hour-long train ride from home, not to mention the time to and from the station.  There was nothing he could do.

As he walked through the door to his private office he got a new message.  Another picture of his wife's face, this time holding a cock, mouth open, apparently licking her way up the shaft.

"I thought you could handle it," she replied.

What the fuck, he thought to himself.  After the moment of shock passed, he stepped into his office and closed the door behind him, locking it.  He sat at his desk and stared at the picture he just received.  "What the hell is going on," he said to himself.

It'd been weeks since that day on the train.  The day she sent him a naked selfie.  The day he dared her to go further.  They never spoke of it.  He never told Aileen about the dreams he'd been having ever since.  He figured she would be disgusted by his perversion, but more than that, he was afraid.  Could he really handle it?

His contemplation was interrupted by another message.  She'd worked her way up to the end of this stranger's cock, and was apparently working her tongue around the tip.  Then he felt the swelling in his pants.  He could almost feel a tongue circling the end of his cock, as if it were actually his in the picture.  He had to find out.

"I can," he replied, "can you?"

After a few moments of eternity, he had his answer.  The new picture was of his wife staring sheepishly at the cock an inch from her face.

"We'll see," she replied.

John felt like he'd been punched in the chest.  Confirmation.

"Then show me," he tapped, following their private script.  He was back on that train, reliving that conversation.  Only this time he would get the outcome he'd been dreaming about.  Or so he thought.

"Whatever," was her retort once again.

"That bitch!" he whispered to himself, dejected.

"jk"

The next thing he saw was her face, her lips wrapped around his cock, her cheeks collapsed from suction.  John's chest burned with anxiety, while his own cock was harder than it'd ever been in his life.  Another picture now.  Her mouth open slightly, tongue out, pressed against the base of his cock as she deep-throats him.

"Want me to stop?" she asked.

"No"

"Me neither"

The next few pictures nearly made him cum.  Taken in succession at arm's length, Aileen appeared to be sitting on their living room sofa, topless, stroking the cock as she sucked it.  Instantly John thought back to a couple weeks earlier, the night she sucked and jacked him off into her mouth, swallowing all his cum.  He couldn't take it anymore.  He began rubbing himself under the desk with his left hand, while staring at the cellphone in his right, completely forgetting he was still at work.

A few minutes later he saw his wife from behind, standing in front of their pool table completely naked, bent over to expose her visibly wet pussy.  Her head was turned back to look at the camera, or her lover.  At this point, he didn't care which, but he was shocked to see that she let him take the picture.  She was really enjoying this.

Finally, he got what he'd been waiting for, dreaming about, all these weeks.  Aileen's lover, still holding the cellphone, had taken the greatest picture he'd ever seen.  A side view of his beautiful wife, bent over their pool table, getting fucked from behind by another man.  He didn't care where he was anymore.  He reached into his pants and started jacking off.

"You like it?" she asked.

"Oh yeah"

John pushed the cellphone under the desk, snapped a picture of his hard cock in-hand, and hit send.

A few minutes later he received something new.  A low-resolution video.  He forgot their cellphones could do that.  Aileen was back in control now, holding the phone in front of her with her outstretched hands.  John watched as her lover pounded her hard from behind.  Listened to his groans.  Heard her squeal as she came.

"Me too," she concluded.

The last message he would get was a picture of Aileen, still laid out over the pool table, an exhausted, yet satisfied smile on her face, her back covered in her lover's cum.  John bit his lip to hold back a moan as he came into his boxer shorts.  He sent one last text to his wife.

"I love you"
