Vector - Ch. 5

5.

Justin toweled himself off in the bedroom.  He’d left Claire in the shower stall, leaning against the glass, panting, in a half-stupor, the water lukewarm.  They’d gone at it in the shower for so long that most of the hot water had been used up.  

Now that his need had been sated, Justin was left only with his shame.  What was he going to do now?  He had a strong urge to confess to Claire, as devastating as that would be for everyone.  At the same time, part of him was convinced that that was absolutely the craziest thing to do, maybe even selfish of him to ruin everyone’s lives just to assuage his own guilt.  

He shouldn’t make any rash decisions, he thought as he pulled on a pair of pants.  He settled on going out and getting breakfast for everyone; it would give himself some time to get away from the house, from his wife and her sister both and clear his head.  Justin finished getting dressed and headed downstairs.

Entering the kitchen, he was surprised to find that the side door was halfway ajar.

At that moment, he was instantly annoyed, nearly forgetting all of the insanity of the last eighteen hours.  It was just like every other fricking time Jane came to visit.  She’d sneak off and smoke a cigarette outside, between their house and the neighbors’.  

The hypocrisy of her smoking was bad enough in itself, given her superior, newfound attitude toward exercise and eating healthy, but beyond that, she’d carelessly leave the door open, letting in the bugs and also some drifts of cigarette smoke, which Claire completely detested.  Barry and Kendra had complained more than once about the smoke wafting in their open windows or the cigarette butts that Jane carelessly tossed about, and while they weren’t particularly close, still Justin and Claire were on friendly terms with them and wanted to keep it that way with the neighbors.

Justin half yanked the door open and headed out, intending to lay into Jane.  No more tip-toeing around that over-sensitive pain-in-the-ass while she went around being a self-righteous jerk.  It occurred in the back of Justin’s mind that he might be overreacting due to everything that had happened, and he could regret whatever was coming next, but he couldn’t bring himself to care.

Only, as he stepped outside, he didn’t find what he expected to see at all.  Jane had indeed been the one to go out there and leave the door open, but, while there was the scent of cigarette smoke hanging in the air, she wasn’t currently smoking, and she wasn’t alone.  

Jane was standing, leaned up against the wall, wearing a floral cami sundress.  The dress was hiked up around her waist, which allowed her to stand with her legs spread wide.  Their neighbor Kendra was on her knees, wearing a skimpy outfit consisting of matching skin tight yoga pants and sports bra.  She was holding Jane’s panties pulled to the side, exposing her slit, which Kendra was industriously licking.

“Yea, that’s good, slut, eat my pussy,” Jane spat through gritted teeth.  She had handfuls of Kendra’s blonde hair in her fists, pulling hard as she humped the neighbor’s face.

Justin was of course in shock, but not in entirety.  This was, after all, why they had kept their distance as neighbors.  Claire and Justin were pretty sure that Kendra and Barry were a swinger couple.  There was a lot of gossip around the neighborhood about the attractive young couple, Barry, tall, well-built,tan, slightly skeezy, with a full head of close-cropped brown hair and Kendra, the classic hot next-door neighbor, looking like a blonde-haired, blue-eyed Instagram model.  

Justin appreciated having some nice eye-candy right next door, and he certainly wasn’t above checking out Kendra when nobody was looking (or fantasizing in the shower), but Claire was offended by the veiled comments their neighbors would occasionally make that were seemingly subtle invitations to swing with them.  She was especially annoyed by the advances Barry would make towards her sister when she would come to visit, being far more forward.  Jane would of course take this as an enormous boost to her ego and flirt back, to Claire and Justin’s irritation, but nothing more had ever come of it.

Until now.

Justin stood there agog as Kendra ate Jane out with a depraved hunger.  Jane was moaning licentiously, unconcerned that anyone would hear, her body moving sinuously against the wall, her pelvis turned out to give Kendra access to all of her nether regions.

“Aw fuck yea, lick my cunt,” Jane groaned, and Kendra gave a muffled moan of arousal at the dirty talk, doubling her efforts.

Justin, despite feeling shameful and sated only a few minutes before, felt his erection instantly tenting his pants once more.  He wasn’t remotely interested in how this superhuman stamina was possible, all he knew was that he was horny as hell once again.

“I’m gonna squirt,” Jane spat out, a nasty, eager tone in her voice.  “I’m gonna squirt all over your whore face...”

Justin’s hot blonde neighbor gave another lustful moan, apparently enjoying being debased in this way.

Justin’s cock was throbbing in his pants.   All he could think of was just how different Jane was from her sister.  Claire was affronted by the very idea of messing around with their free and easy neighbors; Jane was enjoying every second of it, luxuriating in it.  She was just…  such a slut...

“Gonna…  gonna cum…”  Jane’s voice went up an octave, strained, eyes shut tight.  And then a moment later, she groaned, climaxing loudly.

“OHHHHHHHHH..!  OHHHHHHHHH!  Oh-fuck-I’m-cumming,” she choked out, and true to her word, her pussy spasmed and gushed all over Kendra’s face.  The blonde neighbor let out a series of intensifying, muffled moans as she noisily and hungrily lapped at the lubrication dripping from Jane’s convulsing snatch. 

“Mmmmmpph…  Mmmmahhhhmmmm..   Ahhmmmm!”

Kendra fell away, falling on her nicely shaped ass, still mindlessly moaning, a hand rubbing herself compulsively through her yoga pants, which held a large damp spot at the crotch.  Jane also began rubbing her own clit brazen, prolonging her orgasm.  “Ah fuck..!” she snarled, her hips automatically thrusting out at the air.

Justin felt like he was going to explode; he’d never been turned on more in his life at finding yet another surreal fantasy come to life right in front of his own eyes..  Both of these enticing women, acting like horny sluts, outdoors right in between their houses.  His sister-in-law, the aggravating, self-absorbed asshole, acting like a complete total whore…  he felt his mind descending into a fog of mindless lust.  He strode over and grabbed Kendra roughly, hauling her up by a skinny, toned arm.  “Get up!” he barked.

She stood there in front of him, Jane’s lubrication shining on her lips and chin.  Justin was rather unsurprised to see her clear blue eyes were wide and dazed, unfocused, just as Jane’s and Claire’s had been the day before.  

“Go home,” he ordered, giving Kendra a brusque push toward the side entrance of her own house.  “Go lay down.”  In a dreamlike trance, she wandered back inside and softly shut the door.

“Jane.”  Justin glowered.  His head was pounding, his cock was aching.  He felt out of control.  Jane was looking back at him, chest heaving, but her expression was clear and alert, looking like something resembling defiance, but expectant, almost challenging.

“Come here!”  Like Kendra, he grabbed her by the upper arm, peripherally noting how she was maybe even more toned than the neighbor.  She was almost pulled off her feet as he nearly dragged her toward their house, but rather than take her back inside, he threw open the door to the garage.  He yanked Jane through the door, hauling her around him in a wide arc before letting go.  She went stumbling forward, straight into the car fender, her hands slamming onto the car hood as she caught herself.

Justin approached, his hands at his belt, unbuckling it.  Rather than straighten up, Jane remained bent over the car hood, looking over her shoulder, still wearing that waiting expression, panting slightly.  She knew what was coming next.  They both did.

Justin undid his pants, tearing them open and pulling them, along with his boxers, down to his knees, freeing his throbbing, aching erection.  He was breathing hard as he lifted up the brief hem of Jane’s cami dress back up above her hips, then planted his hands on her trim waist.  There was a brief instant where he recalled his hands on his own wife’s waist, barely an hour ago, back when he was wondering what this would be like, and found that Jane’s tiny, trim waist, warm, soft, firm and fit, was even better than he imagined it would be.  He leaned in, found her opening, still slick and dripping wet with the combination of Jane’s lubrication intermixed with Kendra’s saliva; and with a buck of his hips, he pushed inside of her.

Jane keened like a whore as he filled her up, and immediately Justin was thrusting hard, pounding his sister-in-law with urgent need.  Justin could still barely believe this was happening.  He was fucking Claire’s sister.  After all of these years.  This was forbidden, off-limits, and only made more so by how enticing her banging little body was…  Claire was prettier, but she didn’t have a hot, hard body like this…  Fit, primed for fucking…

She felt good, her pussy was so hot and wet and tight.  He couldn’t tell if Claire or Jane was tighter, but it didn’t matter.  Claire was his classy wife.  Jane was a dirty, horny little slut.  It felt good to fuck this whore’s pussy.  

For the few first minutes, he could only grab her by her slim waist, his hands nearly encircling it, thrusting into her so hard that the car was rocking on its suspension, making her squeal, but then his hands were roving all over, feeling up her modest-sized tits through the scant dress, then grabbing, her fit, round ass, squeezing the firm cheeks, pushing them together against his cock.

Jane pushed herself off the hood, still bent over trimly at the waist, hands gripping the fender.  She was pressing her rear back at Justin now, meeting each of his thrust, grunting loudly with each one.

“Uh, uhhh, uh, uhh!”

Oh God, what’re you doing..?

Some last vestige of sanity in Justin’s mind spoke out, trying to salvage something, anything of this situation.  He was an unfaithful, cheating dog.  He’d let Jane give him a blow job, and now less than a day later, he had her bent over his car in the garage of the home he shared with her sister.  He had violated their marriage in every way, there was nothing he hadn’t done with his wife that he hadn’t done with his sister-in-law.  Nothing…

You haven’t cum inside of her yet…

It was a pathetic distinction so far as cheating went. Jane had swallowed for him already, even. Yet, Justin clung to it nonetheless.  It was at least true.  He had gone far, far over the line, but still not so far as that.  If he stopped now, he could still say at least that much…  It wasn’t much, but it was still something…  He could tell himself that he’d never cum in anyone else since Claire…

With an enormous effort, Justin slowed himself, even as he wanted to thrust into Jane’s sopping pussy again and again.  He paused, then gave another involuntary thrust.

“Uhhh!”

 He pulled out, and then couldn’t help himself and slid back in again, hard, eliciting another grunt from Jane.  But then he stayed buried inside, motionless, trying to summon up his will.

“What…  what’re doing?” Jane whimpered, looking over her shoulder.  “Come on!”

She wiggled her ass, pressing herself back against him maddeningly.  

Justin’s hands had returned to Jane’s svelte waist, unable to do more than grip her tightly, the competing urges to pull out and slam her even harder at war with each other.

Jane looked back, rolling her eyes angrily.  “Come… on..!”  She pulled her rear in and then thrust it out again, making Justin groan.  Sweat was dripping down his face.  

“I… I can’t,” Justin panted, even as he stayed buried inside of her.  “I can’t... cum inside of you…”

“What?!”  Jane pumped her ass in that tortuous way again, and then again.  “You’re not going to cum?  You fucking pussy…”

“No…”  Justin’s jaw was clenched so hard, his teeth were aching.  “I… can’t…

“I can’t do that to Claire…”

“Oh.  It’s that…  I see.” Jane sounded suddenly empathetic, understanding.  “I totally get it.

“I’m so sorry.” 

For a moment, Justin was both relieved and disappointed.  Even though the lower reptilian part of his brain, with its relentless desire to mate, wanted this more than anything, he wouldn’t.  He and Jane wouldn’t.  For Claire’s sake.

He took a few deep breaths and then began to reluctantly pull out of Jane’s tight, wet folds.  But as he nearly withdrew, Jane pumped her ass back against him, shoving him back in again.  She and Justin both grunted in pleasure together.

“I’m so sorry,” Jane repeated, looking back, her blue eyes and wide and luminous, the blonde highlights in her hair framing her perspiring face.  “I know you want to stop.  

“Let’s stop.”

Even she said it, she withdrew and then pushed out again, pressing her ass back against him, her tight pussy gripping his shaft.

“Jane… no… I can’t…”

“It’s ok, Justin,” Jane whispered, agreeing, looking back, humping him again.  “I know you want to stop…  We’ll stop…”

She rolled her hips again.

“I know you don’t want to nut in my wet little cunt…”

“Jane…”

“Squirt all of that hot, sticky cum in my tight snatch…”

“Stop…  Jane, shut the fuck up…”

She looked back at him with those wide eyes, a calm consoling expression on her face but she  shuddered again as her lips rubbed up against his balls once more.

“Jane…  Jane, please…”  Justin’s voice was shaking.  He wrapped his arms around her, leaning on top of her, pressing her against the car, but he could neither keep going nor walk away…

Jane was grinding back sensuously , her hips rocking back and forth, her pussy working up and down Justin’s rigid shaft.  His cock was so engorged with blood he thought it might burst.

“You’re right, Justin… That would be so wrong.

“You don’t want this…  All you want is to have boring sex with my prudey sister…

“You don’t want to keep fucking my little ass, right here in your garage, bent over your car…”

She reached behind herself, one hand on each of her round, shapely ass cheeks, spreading them apart wantonly.  Justin didn’t answer, only took in the view she was offering, his balls throbbing.

“Just forget about it.”  Jane’s jaw was clenched just like Justin’s as she tossed her hips back, writhing.

“Stop, Jane, stop…”

He could feel her lubricated wet lips running up and down every inch of him, each little wriggle and pump bring him closer and closer to ejaculation.  The knowledge that Jane wanted the opposite of everything she was saying, wanted him to cum inside of her, was doing everything to make it happen, even though she knew he was trying not to.

It made Justin want to cum inside of her more badly than ever.

He wanted it more than anything.  Wanted to slam up against her perfect, toned ass.  Wanted to squirt deep in her pussy.  Wanted to make his wife’s self-centered, impatient, entitled, bitchy younger sister squeal like a whore while she took his load.

Justin could feel his balls contracting, forcing blazing hot semen up his urethra, the pressure welling up in his cockhead.  It had to come out.  It needed to come out.  There was no holding it back.  He had only a split second to make a decision.  He could pull out of Jane right now.  It wasn’t too late.  Could drop his load on the garage floor, or he could even cum all over Jane’s perky, toned rear and lower back.  That would still be super hot and he could stick to his convictions.  Stay true to Claire.  Save this one last thing for themselves… 

It was as though Jane could read his mind, see his thoughts written on his face.  Still pinned up against the car, she turned at the waist, the dress pulling tight across her modest bust.  She grabbed Justin by the shoulder, her blue eyes locking on his, alight with malicious, wanton lust.  And she pressed her ass against his lap in a series of rough, lewd pumps, moaning decadently with each one, deliberating pushing him over the edge.

The semen erupted out from Justin’s convulsing tool and with a cry as his willpower broke, and with a snarl on his lips, he grabbed Jane by the hair, shoving her face down into the car hood, holding it there as he hammered into his sister-in-law, over and over again, each throbbing pulse of jizz feeling like an orgasm of its own.  His load was impossibly large, seemingly made all the larger by his failed resistance.

“Uhhhh!  Uhhhhhh! Uhhhhhhhhh…!”  Jane called out loudly with mindless pleasure, for anyone to hear, and at that moment, Justin found that he couldn’t care.  It wasn’t important.  Nothing was important other than squirting all of his semen as deeply as possible inside of this sexy whore.   He pulled out and drove himself in compulsively, slamming himself into Jane with wild abandon, fucking her harder than he’d ever fucked a woman in his life.  All of his conflicted anger and frustration, his lust and guilt, all culminated in this throbbing, dripping, sticky, filthy hot moment.  

“Oh fuck..!”  Fuck…”  Justin panted, exhausted, collapsing against Jane, crushing her against the car fender.  His hips kept bucking, wanting to continue screwing beyond his body’s limit, and he couldn’t help notice Jane giving little twitches as well back up against him.

He couldn’t help giving a small involuntary whimper as he pulled out, a generous amount of semen and lubrication flowing out between Jane’s legs as he did so, spattering the floor.  

The moment his orgasm ended, Justin’s sanity immediately came flooding back in.

God, what the fuck was wrong him..?

Justin couldn’t believe he had done this.  This morning he’d been telling himself what a rotten scumbag he was, and now what he had done was immeasurably worse.  He’d fucked his sister-in-law.  Cum inside of her.  There was someone, somewhere who’d have said what he’d done up until now didn’t constitute cheating, but there was no hint of ambiguity now.  He’d done it all, been unfaithful to Claire with a thorough completeness.

With a grimace, he pulled up his boxers over his soiled manhood, re-doing his pants miserably.  Jane was straightening up, still panting hard, sweat dripping down her face, and Justin found even then he wanted her again.  But then she smoothed her brief dress and took a step towards him, her face leaned up, trying to give him a kiss, and Justin found at least this he had the strength to resist.  

Too little, too late, he thought ruefully.

“Go inside,” Justin said quietly.  “I’m going to get breakfast for all of us.”

Leaving Jane standing there looking after him, Justin got in his car, pulled out of the garage and drove off.
