Stepbrother With Benefits (8 page)

Jack felt his cock twitch at that kinky notion, sending a large spurt of lubrication oozing into his boxer shorts.

“Just relax, man,” hissed Mark. “You can enjoy yourself if you want... anything goes around here! And comes, too!”

Mark abruptly pulled Beth’s shoulders backwards towards his chest, arching her spine in reverse and making the bottom of her ribcage stick out, with the little mounds of her firm breasts aimed straight at the ceiling and jiggling delectably.

“Oh, fuck yes,” moaned Beth, twisting her head around to kiss Mark on the lips.

With Beth’s gaping crotch now angled upwards, Jack was unexpectedly presented with a perfect view of their intertwined, thrusting sexes... and he involuntarily groaned, his cock squeezing out yet another sizable squirt of precum. What he was watching was so graphic, so lewd, so
real...
it was nothing short of beautiful!

Noticing where Jack was gawking, Beth reached down and pulled on her pubic mound, stretching out the soft flesh of her pussy. The skin of her hood drew back to expose her clitoris, the pointed nub tinted a slightly lighter shade of pink than the surrounding skin... and yet so swollen from all the sexual activity, it had a hard and glossy appearance.

Jack glanced up at Beth in surprise, and found the teen staring back at him with half-hooded eyes... and a sultry smile. She must really enjoy showing herself off, something that would certainly shine new light on some questionable behavior he’d noticed in the past!

Beth must have been reading his thoughts.

“Tell me, Jack. Back when you lived with Ellie, in the summertime when we were hanging around the pool... did you ever used to wonder what I looked like naked?” she asked quietly, rubbing a finger over her clit. “Because, I sure as hell wondered that about you! Many times late at night, in fact.”

Mark interrupted. “This is no time for a fuckin’ interview, babe, ’cuz I’m almost there!”

The scrawny teen began hopping his crotch up and down at the same time as Beth rocked back and forth, her tight pussy making quiet slurping sounds as they worked as one towards the shared goal of mind-blowing ecstasy.

As the pair moved faster and faster, Beth’s hooded eyes never once diverted from Jack’s face; scrutinizing his expression intently as though it was
him
she were fucking. He found it both highly arousing... and slightly disturbing.

All of a sudden, Mark moaned. “Oh fuck, I’m gonna come!” he gasped. Grabbing Beth’s waist, he jerked his hips sharply upward at the same time as he shoved her body downwards, brutally impaling the little redhead upon the full length of his cock.

“Oh fuck, wait Mark, no! God, I still need another minute!” wailed Beth in anguish, mashing her fingers into her clit in the hope of getting herself off faster.

“Too late!” groaned Mark, the tendons in his legs tensing and his balls retracting tight against his crotch as his body prepared for orgasmic release.

Pull out, pull out!
pleaded Jack in his head, silently hoping that Mark would be a responsible sex partner.

Turns out, he wasn’t.

Jack’s heart skipped a beat when he saw the tube on the underside of Mark’s cock visibly bulge with his first orgasmic contraction; the powerful muscular contraction sending the teenage boy’s fertile seed coursing along his urethra before spurting deep inside Beth’s pussy. Mark’s large hands seized the tiny redhead around the waist so fiercely it looked like he might crush the girl, his fingers squeezing repeatedly into the soft flesh of her abdomen just above the pelvic bone, while poor Beth continued frigging her clit in desperate hope of reaching her own climax.

Jack watched in almost perverse fascination as Mark’s cock throbbed over and over again, at least fifteen times in total, before he finally let out a deep groan and relaxed... his fingers releasing their fierce grip from around Beth’s slender waist, and leaving behind bright red hand-shaped welts on her pale skin. Those would probably turn into some very revealing bruises in a day or two.

With Mark finished and his cock wilting by the second, Beth finally gave up on the idea of reaching her own orgasm and sighed with resignation.

“Damn it all, Mark,” she muttered, lazily running a finger around the perimeter of her pussy, as if trying to memorize the exact details of how their genitals were connected.

Without warning, Mark slid his hands under Beth’s ass and lifted her into a standing position on the floor, Beth shrieking in surprise at being so hastily dismounted.

Positioned halfway between the couches and directly in front of Jack, Beth bent her knees and looked tentatively between her legs... just as a thick glob of whitish cum oozed from her inflamed hole.

The glob stretched downwards on a long, gooey strand that dangled precariously between her thighs, before suddenly breaking away and landing with an audible splat on the floor. Another glob appeared almost immediately, this one dripping away sooner and landing beside the first, followed by another and another, until there was an almost continuous trickle of thick fluids seeping from her abused sex.

“Oh my god,” she muttered, pushing her pelvis forwards and using two fingers to part the swollen folds of her pussy, so she could get a better look at her post-coital condition.

Jack’s heart caught in his throat. His sister’s nineteen-year-old best friend was barely a foot away from him, practically
forcing
him to look at her just-fucked pussy as it literally dripped with globs of sticky semen.

With a soft grunt, Beth spread her outer lips far enough that her stubby inner labia stuck out like a pair of trembling pink petals. Pushing with her vaginal muscles, the tiny hole of her urethra moved forwards and downwards as the mouth of her sex dilated open... and then, after a brief pause, a veritable river of Mark’s stark white cum gushed from inside her canal, splattering noisily on the scuffed linoleum floor between her bare feet.

Jack was so close to the lurid spectacle, he could actually
smell
the pungent odors of Mark’s fresh seed and Beth’s extremely horny pussy wafting towards him. Jack’s dick lurched and leaked another gush of precum – his poor boxers were going to be an absolute mess!

When that first rush of Mark’s seminal fluids petered out, Beth adjusted her fingers and flexed her pussy again, closing her eyes and shivering as a second load of cum was noisily expelled onto the apartment floor.

Jack was literally stunned. Even during his own sex-crazed years at college, he’d never witnessed anyone doing anything like this before!

Giving the stubby wings of her inner labia a quick flick to knock off the last clinging droplets of cum, Beth straightened up and smiled at Jack, shrugging her shoulders in mild amusement. “Heh... as you can see, Mark has the tendency to make a shitload of cum,” she commented casually, as though this were a typical morning event for her.

The more Jack thought about it... maybe it was!

From the other couch, Mark abruptly jumped up. “Gotta whizz!” he announced brusquely, giving Beth’s ass a loud smack before dashing off to the bathroom.

Beth called after him in irritation. “Hey, what about me! The deal is we
both
fuckin’ get to get off, you selfish jerk!”

Collapsing back on the couch, Beth raised her feet up onto the cushion and hugged her knees to her chest. With a frown on her face, she looked across at Jack.

“Well, pooh. Now I’m gonna be horny all day.” Pointedly scanning Jack’s reclined, blanket-covered body, Beth suddenly got excited. “Hey, you wanna maybe help me take care of that?” she asked, brazenly spreading her legs and sliding her middle finger along her puffy slit. She dipped the tip inside her inflamed hole, and somehow there was still enough of Mark’s cum trapped inside for a small trickle to run tantalizingly over her asshole, before ultimately dripping onto the cushion.

Suddenly, all of those mysterious stains on the couches made perfect sense!

“I know from personal experience that sloppy seconds can be a lot of fun,” she said with a snicker, thrusting the penetrating finger and making wet, sticky sounds.

See? This finger could be you, Jack!

Even though Jack had never double-teamed a single girl before, his painfully engorged cock twitched violently at Beth’s kinky offer.

Jack was certain that most any man his age would eagerly accept Beth’s offer without so much as a second thought. But, in his heart, he knew it could never be. For one, Ellie would surely disown him if she ever found out he’d slept with her best friend – and his stepsister was far too important to Jack for him to jeopardize their relationship over a mere moment of pleasure.

Even if it would probably be a really good moment!

“Uh, I don’t think so, Beth,” he replied with no small amount of regret.

“Why? You turned gay or something?” She pulled the wet finger from her pussy and stuck it in her mouth, playfully sucking off its coating of cum and pussy juice.

Jack groaned and scraped his fingernails across his stubbled cheek. Resisting her was taking a herculean effort! “No, Beth, I’m definitely not gay. Far from it. It’s just... it’s just kinda complicated.”

“What could be so complicated? You’re a great guy, and I always did have something of a childhood crush on you... it’d be fun for us to finally hook up! Don’t you think so too?”

Jack’s raging libido screamed at him to stop refusing such an appealing invitation, that there was no one in his life he would be cheating on... but for some reason his conscious simply wouldn’t allow him to give in. “Uh, really, thanks... but... I can’t. You’re a beautiful woman, Beth, and obviously very comfortable with your body and yourself...” He tried to think of a decent excuse that wouldn’t put the blame squarely on his sister. “...But, I feel like I’d be taking advantage of you.”

“What?”
she gasped. “Of
course
you wouldn’t! Geez, I just wanna get off before class, not marry you or something! What’s so complicated about that?”

“No, Beth.” It quite literally pained him to say this.

Beth sighed and lowered her gaze in defeat. “Well... damn it all, Jack. You really are something special. I think any woman would be lucky to have you.” Then, she looked at him with a smirk and resumed rubbing her clit. “But that doesn’t mean I’m gonna stop tryin’ to convince you to finally have some fuckin’ fun!”

With a dramatic groan, Jack leaned back and pulled the blanket over his head. There was definitely no way he was going to survive the rest of this week intact!

W
hen Mark
finished in the bathroom and Beth was able to take his place, Jack was finally left alone to deal with his jumbled thoughts... and one of the hardest erections of his life.

Jack’s shy nature didn’t permit him to be anywhere near as sexually open as these brazen teens, and between the bathroom being occupied and the constant danger that someone could walk in at any moment, Jack knew he couldn’t take care of his condition in the “normal” way.

Instead, he lay back and attempted to dull his body’s unwanted sexual response by rhyming off the depressingly long list of things that still had to happen for his re-worked proposal to succeed.

Sure enough, the sobering trick worked... and gave him a mild case of anxiety!

When Jack’s alarm needlessly sounded ten minutes later, he was ready to get up and make morning coffee for everyone. Although the front of his boxers were still soaking wet, he couldn’t yet change and hadn’t thought to pack a robe – and hoped the fact that they were dark in color and loose fitting would be sufficient to hide their unsavory condition.

The sounds of voices and movement in the other half of the apartment grew louder as everyone prepared for the day. Jack was desperate for a few private minutes with Ellie to discuss what he’d just seen, and was relieved when she was the first one to come down the hall – barefoot and in a red T-shirt and grey sweatpants that would undoubtedly change before class.

But instead of walking directly into the kitchen, she disappeared into the living room – probably to turn on the television – and suddenly cried out in surprise.

“Mark, dude, like what the fuck, man!” she exclaimed angrily.

“Oh – sorry, El!” came the muffled reply through the thin bedroom wall.

“Learn to clean up your own fuckin’ puddles of fuck-juice!” she yelled back at him.

“Sorry!”
repeated Mark in a higher pitch.

A few seconds later, Ellie appeared around the corner, hopping into the kitchen on one foot.

“Uh, bro... could you get me something to clean this shit off with?” she asked, lifting her left foot higher to show him the sticky white substance covering the sole of her foot.

Jack nearly had a heart attack. Mark’s cum. From inside Beth’s pussy. All over his sister’s foot! Nervously, he ripped off a few squares of paper towel from the roll and handed them to Ellie.

It took his sister nearly a minute to clean herself – cum had even squoozed up between her toes! When she’d finished and was about to toss the dirty towel into the trash, Ellie hesitated and brought it under her nose. Sniffing deeply, she frowned and held it out to Jack.
