Stepbrother With Benefits Read online

  She was genuinely proud of being able to swallow Mark whole!

  Mark groaned and ran his fingers through Beth’s long red hair as she tried moving her head up and down like before, although she really wasn’t capable of that and began choking almost immediately.

  Quickly pulling off, Mark’s glans made a loud sucking sound as air squeezed past the vacuum of Beth’s lips.

  “Cool, huh?” she asked, wiping the drool from around her mouth. “I learned how to do that from a video on the ’net.” Beth giggled as she thought of something. “I knew that interweb thing would prove useful for more than just boring old school research, am I right!”

  Jack held back his own laugh... because he was afraid he might groan lustfully instead!

  “Everything I needed to know, I learned from the internet,” quipped Mark.

  Beth rolled her eyes. “Along with a hell of a lot of shit that no one should ever know! Anyways, I will say it feels real weird if Mark comes when we’re like that... kinda like I’m sipping hot chocolate, but I don’t even get any kinda taste.”

  “I thought you said you didn’t like the taste of jizz.”

  “I never said that! What I said, is if you’d change your diet to include less red meat, then your cum would taste better.”

  “...And that matters because?”

  “Don’t be so obtuse, Mark. You do want girls to want to swallow that shit, right?”

  As the oldest and clearly most uncomfortable one in the apartment, Jack was by now feeling the compulsion to say something... responsible. “Uh, guys, you sure you don’t want to take that somewhere more private?”

  Standing up, Beth rotated around and glanced at Jack with a goofy grin on her face. Even with that ridiculous expression, she still managed to look amazingly hot – small breasts proud and perky, porcelain white body soft and beautiful, and with that shock of long red hair cascading all around her shoulders.

  “Why would we want to do that, Jack? We’re here now, and knowing Mark’s quick trigger... I don’t think we’ll be much longer.”

  Mark grunted with annoyance and slapped Beth firmly across both buttocks, making the girl screech and jump. “Hey, no insulting the talent, babe!”

  “You call that talent?” replied Beth, waving her hand disparagingly towards his otherwise impressive-looking phallus. “Three-quarters of the time you get off before me, and I end up having to finish by myself!”

  “Just get that tight little cunt of yours back on here and we’ll see about that.”

  Beth snorted. “Oh, gee. You always know what to say to make a girl weak in the knees... not!”

  Backing herself between Mark’s spread legs in a reverse cowgirl position, Beth positioned her pussy above his crotch and grabbed his cock, rubbing it back and forth along her slit and slapping the purple head repeatedly against her clit. Finally, she held it straight and lined herself up, then eased down until she bottomed out with a grunt.

  Although Jack had already seen the two teens coupled from the rear, it continued to fascinate him how such a tiny girl could so easily take that huge prick – watching Mark slip inside, he had to be penetrating past her navel! As Beth resumed bouncing up and down, Jack’s own erection grew hard enough that it began to hurt with every beat of his heart; like pulsing twinges of pain that pleaded for his immediate attention. However, Jack refused to give in and touch himself, since he didn’t want to do anything he might end up regretting.

  “Ah fuck, Mark... if there’s any talent to be had, it’s with your parents for making you in the first place!”

  “Thanks babe, that’s really sweet. But I still had to teach myself how to use what my mamma gave me.”

  “Oh, right!” laughed Beth. “Insert tab A into slot A is not much of a skill set.”

  “But babe, your slot A is so very tiny, and you won’t even let me try slot B.”

  “And you won’t ever get to at this rate. But enough already – just fuck me, ’cuz I need to get off before class!”

  Spreading her knees and leaning forwards, Beth rocked her hips as she humped against Mark in short, rapid motions. Mark reached under her arms and cupped her breasts, his large hands squeezing and playing with the little swells as though they were stress toys – tweaking her long nipples between his fingertips so forcefully, that the once tender pink skin quickly turned an angry shade of red.

  Although Jack was by now unbearably aroused and enjoying every second of the amateur sex show, he nonetheless felt deeply self-conscious about the circumstance. He wasn’t exactly used to seeing this sort of thing live and in person, and figured he shouldn’t be absorbing such intimate knowledge of a girl he’d known when she was in grade school.

  Regretfully forcing himself to turn away, Jack tried looking out the window to distract himself with more mundane thoughts.

  Was it going to snow again today? He’d forgotten to check the weather report last night. It looked like it was going to be a clear morning, but he knew that could change at the drop of a hat.

  Beth must have noticed his shift in attitude. “You know, Jack...” she coaxed in a soothing tone, “we really don’t mind if you watch. We like being open with each other around here.”

  Warily turning back to the couple, Jack found Beth leaning forwards and staring straight right at him – her hooded eyes barely two feet away from his own. He felt his face instantly flush hot, both from the uncomfortable proximity, and her rather seductive expression. “You two really should be doing that in private,” he murmured.

  “Oh, we’re all totally used to doin’ it in front of everyone by now... so there’s nothing to hide. It’s totally freeing. And besides, you’re Ellie’s big brother, so you’re just like family!”

  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 hi
m 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 groa
n, 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!

  Chapter Eight

  When 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.
