Stepbrother With Benefits (16 page)

Moving high over Ellie and driving into her pussy with an animalistic ferocity worthy of fourteen months sexual abstinence, Jack hunched up and down as though he were doing pushups, their sweaty skin producing a serious of sharp slapping sounds that echoed in the room around them. Ellie took the opportunity to run her fingers over the muscular definition of her brother’s broad chest, tweaking his erect nipples and twirling her fingers through the small patch of curly chest hair.

“Yes! Yes! Fuck, yes... harder!” moaned Ellie, abruptly pulling Jack’s head to hers and kissing him passionately.

Ellie’s near-constant moaning soon transitioned into uninhibited shrieks of joy – loud enough that the neighbors surely had to be able to hear! Would there soon be an angry knock at the door, or was boisterous lovemaking not a particularly rare event around here?

All of a sudden, Ellie bent her head back and dug her razor-sharp fingernails into Jack’s back, letting out a guttural scream that twisted her face into an expression of carnal agony.

“Yes, yes, god, fuck me harder, I’m almost there!” she gasped – something Jack had already sensed from the increasing rigidity of Ellie’s pussy.

Knowing that his sister was about to come was an extraordinarily powerful aphrodisiac to Jack. Suddenly feeling his own fluids begin to shift and flow, Jack pulled his hips back and drove hard into Ellie one, two, three times in a row. With the tendons in his legs straining and his buttocks clenched tight, Jack felt the excruciating need to attain physical release spread from a dull ache centered deep in his groin, to a tingling sensation that traveled all the way along his urethra.

But then, just moments before Jack would have reached his orgasmic peak, an unexpected and completely unwelcome question popped into his head.

Is Ellie on the pill?

He never thought to ask her that!

Abruptly fearful that he might accidentally get his own stepsister pregnant, Jack’s orgasm stalled and he frantically tried to pull out before it was too late – only Ellie’s legs were wrapped securely around his torso, and refused to let him move even the slightest bit away.

“Ellie...” he began in hoarse desperation... but she cut him off with four words. Four simple words that he would never have expected to pass through her lips:

“Come inside me, brother!”

Hearing something so depraved and yet so completely perfect for the moment, thrust Jack clear past the point of no return.

Growling like a wild animal, Jack’s brain snapped into a primal state – with normal, rational thought fading away, leaving only the singular and altogether ancient goal of injecting every drop of his body’s biological seed as deep as he could into the female mounted beneath him.

Jack’s arm slid between the cushion and the small of Ellie’s back, grabbing her ass and jerking her groin against his with as much force as he could muster – at the exact same moment as his cock swelled thicker, throbbed powerfully inside her pussy, and then all but exploded in a mammoth gush of long pent-up cum.

So much fluid flooded out on that first mighty contraction, that Jack swore he could feel the pressure of his semen rippling in an unbroken torrent along his urethra for several seconds, as though pissing a solid stream of semen. He could even sense a kind of backpressure against his glans as the powerful jet erupted, and figured he’d pushed so deep inside his sister’s pussy, that he was attempting to inject his sperm directly into Ellie’s womb.

As the raging river of ejaculate hurried to fill Ellie’s pussy, she reached her own violent orgasm and began screaming, “Oh fuck!” in a repeating loop. The orgasmic teen’s limbs stiffened, her back arching even further off the cushion as her legs squeezed possessively around her big brother’s shuddering torso... all while the churning walls of her pussy milked his spurting cock for every precious drop of his sexual essence. Expand, contract, expand, contract... over and over again, the two of them locked in perfectly synchronized orgasmic rapture.

Jack couldn’t breathe, couldn’t speak – could barely even
think
– his brain simply following the basic instinct to keep their bodies joined together as he surrendered body and soul to the euphoric reward of delivering his reproductive payload.

After nearly twenty utterly fulfilling convulsions, Jack’s orgasm came to an abrupt end and he collapsed on top of Ellie, physically spent and far too weak to consider moving. The main part of Ellie’s climax was also finished, although she seemed to be in a state of perpetual orgasmic aftershocks, with her ravenous pussy squeezing sporadically, as if milking his cock of any remaining trickles of cum.

Ha! Like there was any fluid left in his body...

Sweaty and winded, the intertwined couple recovered on the couch for several minutes, before Ellie finally shifted her arms just enough to hug her sweaty brother, sighing deeply and giving him a noisy smack on his cheek.

“Oh... my... god,” she moaned. “That was just
amazing!
You have no idea how happy you’ve made me.”

Jack groaned, his tingling cock still hard and lodged deep inside Ellie’s pussy. He’d always found the act of climaxing simultaneously with his partner to be a mind-blowing experience, but there was something even
more
special about what had just happened with Ellie. It was as if their bodies were so in tune with each other, they’d somehow fed off each other’s orgasms – their timing uncannily synchronized to extend the pleasure for far longer than should’ve been possible.

Basking in mindless overjoyed satisfaction, it took Jack quite some time before the full extent of what he and Ellie had just done dawned on him.

He’d come inside Ellie. Hmm.
His semen was inside his little sister!

Jack’s first instinct was to panic.

“Oh shit! Shit, shit, shit! I can’t believe we just did that! I’m so, so sorry, Ellie... I really shouldn’t have come in you! God, what are we gonna do?”

Ellie giggled and stroked her hands up and down her brother’s knotted back. “Don’t be silly, Jack. Calm down. You did exactly what I told you to do! And wasn’t it beautiful? Only our first time together, and we came at the same time! It was like total perfection! I swear, we really are meant to be with each other.” She kissed him again, this time full on the lips.

Unconvinced, Jack grumbled into Ellie’s mouth, even though his body felt rather differently. For only the third or fourth time in his life, his penis wasn’t going soft after such an intense orgasm. Breaking the heated kiss with Ellie, Jack pushed himself upright while carefully keeping their sexes coupled together. Their bodies were literally stuck to each other with sweat, and he could feel their skin progressively peel apart.

Ellie wiggled her hips, giggling in surprise at his engorged condition. “Wow, Jack. I can’t believe you’re still hard! Did you want to give it another go or something?”

Jack snorted – Ellie must be an insatiable! Not that he was in any position to judge. “Actually, sis, I just need to check on something first.” Namely, the aftermath of his handiwork.

Carefully inching backwards, the long lips of Ellie’s swollen labia hugged Jack’s cock as he slowly withdrew from her sex, the wide flare of his head finally clearing her threshold with an obscene wet sucking sound. Almost immediately, a burst of thick white cum erupted from inside Ellie’s pussy – held under so much pressure that it sprayed a good four inches across the cushion in a thick, gooey streak.

Feeling the pressure release, Ellie groaned and propped herself up on an elbow. “Holy shit, Jack!” she gasped in wonderment. “I think you can give Mark a run for the money in the cum-making department!”

Biting her tongue mischievously, Ellie spread her lips so she could better see as a veritable river of her brother’s cum drained from her pussy – trickling down the crack of her ass and onto the couch, where it began to form a puddle in the depression around her buttocks.

“Oh my god, this is so fuckin’ hot! I just love it! Do ya remember what I was saying the other day? That there’s nothing like feeling your man’s cum inside you? You’ve sure given me that!” She then added with a giggle, “Shit... though I never expected there to be so much on the outside, too!”

When the flow began to taper off, Jack prodded gingerly around the mouth of Ellie’s sex. Noticing a little web of skin stretching across the bottom that seemed to be keeping a pool trapped inside, he gently bent the delicate flap downwards, watching smugly as thick, boiling hot juices poured over his finger. There seemed to be no end!

“Oh hell, sis... there’s just so much,” whispered Jack uneasily, refusing to acknowledge even the vague
possibility
that Ellie might not be on birth control pills. Hopefully her complete lack of concern meant that they weren’t in any immediate danger.

“Heh, you’re telling me! You’re like a gangbang in one guy! Um, not that I’ve tried one of those... yet...”

“Uh huh. Well, I honestly don’t think I’ve ever come so hard before... so either there’s something in the water around here, or you bring out the best in me.”

“I’ll take the latter option,” she offered in a husky tone, staring directly at Jack’s still-erect cock. “Although, as sexy as it is to feel the best of you leaking out of me, I still think I’d prefer it stay put. Where it belongs.”

Jack’s brain had difficulty grasping Ellie’s words.

Suddenly bolting upright, Ellie grabbed her brother’s wet cock and gave it a couple of test squeezes. “Fuck, Jack... I can’t believe you’re still so hard,” she whispered in fascination. Leaning forward, she promptly wrapped her lips around the head of his cock and sucked him into her mouth, slurping noisily as she cleaned off the thin coating of aftermath.

Holding the back of Ellie’s bobbing head, Jack groaned and shivered from head to toe as she licked and teased his glans with her tongue. Out of the blue his pelvic muscles convulsed fiercely, and a squirt of something shot into her mouth – he wasn’t sure whether it was leftover cum, more precum, or
whatever,
but his sister seemed to take notice and hummed in surprise.

Pulling her mouth off with a humorous popping sound, Ellie promptly turned over on her hands and knees, feet dangling off the front of the cum-soaked couch and ass waggling seductively in the air.

“C’mon, Jack!” she invited with a huge grin. “I’m pretty sure we’re both ready for that second deposit now!”

M
oving off
the couch, Jack was given his first real look at Ellie from the rear – with the vertical line of her cleft and bulls-eye of her asshole stacked up like an inverted exclamation mark.

Salivating, Jack stroked himself and licked his lips. For some reason, this had always been his favorite view of a naked woman!

Holding his throbbing cock out straight, Jack stepped behind Ellie and aligned himself with the swollen lips of her pussy. Wedging the head between her labia, he made a little wiggling motion with his hips, and was quickly directed into the hole he sought.

God – Ellie’s pussy was completely drenched! Which wasn’t necessarily surprising, but knowing how wet she’d been before they’d even started... this had to be more than his own juices!

“Oh, fuck yes!” moaned Ellie, rocking her ass back and forth and trying to hump herself on the end of his cock.

Jack chucked. “Relax, El! You’re always in such a rush.”

“I’ve been waiting far too long to be all patient and understanding now! And I’ve always been kinda multi-orgasmic anyways... it takes me like two or three times before I
really
feel satisfied.”

“Heh, good to know, I guess. Two times I can probably handle. But three? I think you might be pushing your luck there!”

“Well, Jack... you’ll just have to learn to keep up with me!”

Gripping Ellie’s curvy hips, Jack leaned forwards and sank excruciatingly slowly into the exquisite tightness of Ellie’s molten sheath. The two were soon fucking hard and fast, the repeated impact of their sweaty bodies filling the living room with the uniquely arousing sound of damp flesh slapping together. Jack allowed his eyes to roam lustfully over his sister’s perfect figure: her long, graceful neck... the delicate curve and scalloping of her spine... the narrow waist that didn’t even look half as wide as her ass... even the two cute little divots right above her buttocks. And most especially, how he could just see the sides of Ellie’s large breasts swinging back and forth under her chest.

Noticing something interesting, Jack used his thumb to trace a distinctive thin line of bright pink skin that ran from the top of Ellie’s ass crack, along the back of the groove, until meeting up with the vibrant patch of red skin surrounding her asshole. Reaching the puckered depression, he pressed the pad of his thumb on top and felt the puckered ring of her sphincter moving up and down as his cock thrust in and out below.

Rubbing her asshole a little harder, Ellie must have relaxed her muscles because all of a sudden his thumb popped inside, sinking clear up to the last knuckle.

Ellie gasped in surprise and clenched her buttocks. “Oh Jack... you’re such a naughty boy!” she proclaimed with a girlish giggle.
