Vector - Ch. 3

3.

Justin stood there at the sink, absently scrubbing the dishes, warm water hissing from the faucet, trying to figure out what to say.  He figured that with Claire lying down upstairs, this was the perfect time to try to talk to Jane and make sure she wasn’t going to tell her sister about the car ride, but he couldn’t see how he could accomplish that while she was in this zoned-out state.

Well, he’d have to try anyway, he thought grimly to himself as he scrubbed the last of the plates, moving on to the glasses.  He tried to formulate how he was going to start off the conversation, when suddenly a pair of arms encircled his waist from behind.

“Hey,” a voice whispered softly, inches from his ear.  Startled, Justin half-turned, looking over his shoulder to see Jane had unexpectedly come up behind him.  She was decidedly more alert now.

“I just wanted to say thanks for earlier,” she breathed in his ear.  Her hands were moving lower now, feeling him up through his jeans, and Justin felt his manhood immediately responding despite himself.

“Whoa, whoa, hang on,” he said, not too loudly, as he whipped around, catching his sister-in-law by the wrists and gently but firmly pushing her hands back towards her sides as he glanced up at the staircase, but then just as quickly she was reaching out again.

“What’re you doing?!” Justin whispered harshly, keeping his voice below the volume of the still-running kitchen faucet.

“Oh c’mon,” Jane coaxed.  “It was so good… You liked it, didn’t you..?”

“I..  That…”  he stammered, still fending her off, before finding words.  “That’s not the point!  We can’t do that!  Especially not right here, not right now!

“Oh…”  Jane stopped struggling to get at him, a small smile of anticipation on her face now.  “So… later, somewhere else..?”

“No..!”  Justin was extremely flustered.  “That’s not what I meant!  And that besides… we have to talk.  If Claire were to find out about any of this, she’d be devastated.”

Jane merely rolled her eyes.  “Don’t worry, I’m not trying to wreck your home.  I just need… a little more of what I had earlier…”

Justin still had her by wrists, but rather than try to struggle against him, Jane simply stepped in, closing the distance between them.  She was looking up at him with her head tilted to the side, in an incredibly alluring, playful, sexy way, her lips slightly parted, biting the tip of her tongue.

For one brief insane moment, Justin felt the urge to let go of her, let her do whatever she wanted.  But then, his reason and decency reasserted control.  He pushed her back again firmly.

“Jane, what happened in the car was a terrible mistake.  I don’t know what I was thinking.  I – we – can’t ever do anything like that again.”

He immediately turned away and made to exit the kitchen, before pausing and turning at the doorway.

“Please, please don’t tell Claire.”

Jane had a dainty finger in her mouth now, toying with her lips, her eyes wide and alluring, silently beckoning him back.  “I won’t…”

With some reluctance he pretended he didn’t feel, Justin turned away and headed up the stairs, his erection throbbing in his pants.

***

The master bedroom door was closed, and he opened it quietly to find that the lights were off and Claire was motionless in bed.  Justin tiptoed to the in-suite bathroom, and turned on the shower.  He brushed his teeth as he waited for the water to get hot.

His mind was a whirl at what had happened today.  This was nuts, he thought again for the umpteenth time.  Jane.  Claire’s sister.  Divorced now, looking fitter and sexier than ever.  Now more annoyingly full of herself as a result.  The bratty, sexy sister-in-law that he half-despised and was half attracted to… about whom he’d always wondered whether the feeling was mutual.

The way she’d thrown herself at him, the sensation of her mouth on him…  His erection was still throbbing.

Lost in his thoughts, he was totally taken off guard when a pair of arms encircled his waist again for a second time in the last thirty minutes.  Alarmed, he looked in the mirror and saw that it was Claire, which he was half-relieved, half-stricken by.  Justin swore he could see the guilt written all over his face in the reflection.

He tried to rather ignore her, spitting into the sink and rinsing out his mouth, but just as Jane’s hands had done only a little while ago, his wife’s were caressing his thighs, and then his manhood through his jeans.

He turned, wiping his mouth across the back of his hand, his wife gazing up at him with her pretty face.  He couldn’t recall ever seeing such an expression on her face, one of focused determination and powerful longing, and couldn’t help but think that it was the same one that had been on her sister’s face down in the kitchen. He noticed then that Claire was wearing an extremely sexy black lace teddy, the type of nighttime attire she usually reserved for Valentine’s Day.  She was still rubbing him, and now undoing his belt buckle.

“Whoa, Claire,” Justin managed to get out.  “What’s going on..?!”

If Justin had a complaint about his wife, it was that they didn’t do it often enough.  Claire wasn’t bad in bed but not particularly adventurous either.  She didn’t generally want to have sex more than once or twice a month.  For her to throw herself at him like this was quite abnormal, and the timing of it all…

“Hang on,” Justin balked.  “I need to just rinse off real quick…”

She didn’t heed his words at all, getting down on her knees in front of him, still undoing his pants.  The gears in Justin’s mind were spinning frantically again, switching between thoughts of guilt, confusion, and lust.  He wondered if Claire could smell her sister’s perfume on his pants.  Why was she throwing herself at him anyway..?  This was so unlike her.  And then oral was never her thing anyway, she hardly ever did that.

And the most tortuous thought of all… his cock had just been in her sister’s mouth and now it was about to be in Claire’s…  It was… like something out of a depraved, guilty fantasy.  Something that shouldn’t have him so turned on, but undeniably did.  It meant that he was a cheating scumbag, unfaithful to his beautiful, classy wife, with her own sister no less, but the primitive, animal lust instincts built into the lower part of his brain were driven by the dirty smuttiness of it.

Claire had his pants open, was pulling his massive hard-on out his boxer shorts, her chest heaving in the low-cut nightie, her lips parted.

“Wait..”  Even as a bead of pre-cum oozed from his swollen head, Justin hesitated, both dying to let this happen and too ashamed to allow it, while overcome with fear that Claire could somehow tell what had happened earlier.  He hadn’t even showered yet…

But his wife made the decision for him.  She slowly bobbed her head down, sucking on his glans first, then taking the length of him into her hot, wet mouth, with an inexorable suction.

Justin clutched Claire by her auburn head, unable to do more than mentally struggle between pulling her away and yanking her further down toward his balls.

She was sucking him off.  His wife was giving him a blow job mere hours after her sister had done the same.  The thought that he hadn’t even showered was driving him to distraction.  Unbeknownst to her, Claire was sucking her own sister’s saliva off her husband’s cock.

You’re a sick fuck.  You’re a perverted piece of shit, Justin berated himself miserably.

It didn’t change the fact that his balls were aching, threatening to release at any second as his wife’s head bobbed up and down, licking and sucking.  The emotional heat of the moment was amplified by the actual steam of the bathroom, as the unattended shower continued to pour water.

“Claire… wait” he muttered, even as his hips began thrusting forward, and he really was pulling her hair now, fucking her face.

I can’t, Justin thought, even though it was the complete opposite of what he wanted.  This is so wrong...  

He thought again of how he’d never cum in his wife’s mouth before.  That he would for the first time, on the same day as he’d cum in her sister’s mouth, was so just depravedly filthy, so obscene…

Justin grit his teeth, holding on with all of his might, as Claire continued sucking him off, trying to coax it out with an eagerness she’d never displayed before throughout their relationship.

I…  I can’t…  I shouldn’t... shouldn't want this…

“Stop…  You’re going to make me…”

Justin was fighting an impossible battle, his better nature losing in the face of his baser instincts.  But what put him over the top was the movement he caught out of his peripheral vision; he looked up to see through the open bathroom door, across the bedroom, the door to the hallway ajar as well.  And Jane was standing there in the doorway.

Justin had a sudden vision of how he and Claire must look from her point of view; him standing there facing her with his pants around his ankles, her sister on her knees with her back to her, her dark hair bouncing up and down, servicing him.

Jane’s jeans were unbuttoned too.  A hand was down inside of her panties, working furiously, while the other was feeling up one of her decently-sized tits through her halter top.

She’d been watching them.  Getting off on seeing her own sister suck off her brother-in-law.  Just like she’d done earlier in the day.  Brazenly touching herself, right in front of him, not even trying to hide it.  If Claire so much as turned her head, she’d see Jane there, standing in the doorway of their bedroom, fingering herself.

But Claire wasn’t likely to notice.  She was focused solely on getting off her husband, sucking Justin like a vacuum, stroking his shaft up and down in her hand with a twisting motion she’d never used on him before.

With his wife’s oral pleasuring, her sister standing across the room groping herself in plain view, Justin couldn’t help himself, whatever his reservations and feelings of guilt.  His eyes locking with Jane’s, he let out a loud cry as he unloaded into Claire’s mouth, cumming just as hard as he had earlier in the day, the semen virtually blasting the back of his wife’s throat.  Over the white noise of the running shower, he could hear Jane moaning, her face contorted with ecstasy, but Claire didn’t appear to notice, letting out lewd moans of her own as she swallowed his load, her delicate throat working, the copious amount of seed first coating Justin’s shaft as he involuntarily pumped in and out of his wife’s mouth, then dripping off of Claire’s lips as she kept them wrapped around his manhood.

Justin stood there for several moments, panting hard, the thick, steam-filled air heavy in his lungs. Still clutching fistfuls of Claire’s hair, he shuddered as she gave him one last hard suck before letting his softening member fall out of her mouth, a long strand of mingled drool and jizz trailing out and dribbling down her chin.

He looked at Jane across the way, leaning against the doorframe, head turned upwards, relishing the ending glow from her own climax.  Silently, he willed her to look back at him and, what felt like an eternity later, she finally did open her eyes again.  Justin gave her a few frantic jerks of the head.  Although Jane didn’t appear to acknowledge him, she slid out of view shortly after, and Justin, relieved, let go of Claire’s hair, leaning back on the bathroom vanity, chest still heaving.

Claire eventually rose, also still breathing heavily.  Her eyes were wide and luminous, though they’d gone unfocused again, her lips slightly parted, still glistening with the mix of saliva and semen.  Justin felt his loins stir slightly, a feeling of prurient awe falling over him at this new look he’d never have expected his wife to be wearing.

But then, as her sister had done back in the car, she swiped clumsily at her mouth, then turned away without a word and stumbled back to bed, where she appeared to immediately fall asleep.

Justin hitched his pants back up and watched her for a long time before finally getting into the shower, wondering for the millionth time what was going on.
