Don Weathers was so hard it almost hurt-- it was truly uncomfortable to press down on his too-stiff shaft and teasingly draw the knob of his cock-head through Bethany's swollen and weeping furrow. The leverage of the act put such torque on his body that he had to resist the urge to rise up on his toes. It was worth it, of course, the slobbering kiss of her wet, heated labia upon his sensitive tip being more than adequate compensation for any positioning inconvenience.

It was no wonder that the forty-five year old sales manager was erect: not only was he at last upon the verge of breaking his self-enforced five-day abstention from fourteen-year-old pussy, but the tableau before him could not have been more arousing. The girl's head lay on her own mother's bed, her lovely face turned leftward in profile, her shoulders and even her chest pressed into the duvet, while her supple back curved in feline arch, elevating her tight bottom and prominent pudenda atop spread knees and smooth upper legs like an offering.

To ornament this delightful pose, add a hairless vulva, flushed and glistening in obvious unmet need, confessing in its state the influence of biofeedback conditioning, the eighth-grader's own period of sexual denial, and the primal, evolutionary instinct her double-x chromosomal make-up naturally brought to the occasion; given all of this, the tumescence inspired in the crotch of the youngster's guardian is already sufficiently explained.

Indeed, this combination of factors would be plenty to make any heterosexual male's penis engorge, but in addition Don Weathers had taken, about thirty minutes earlier, two little blue tablets, trade name "Viagra", a medication intended, in a single dose, to aid gentlemen suffering from erectile dysfunction to achieve serviceable genital states so that they might engage in coitus that would be otherwise unachievable for them. Don did not suffer from this condition, and so his use of the pharmaceutical could technically be described as "prescription drug abuse."

His taking double the standard dose could be reproved as "failure to take this medication as directed."

And should his use of the product result in an erection lasting more than four hours, it would be fair to accuse him of "failing to heed label warnings", for under no circumstances would he be seeking "immediate medical attention."

Should such a condition result from his dosing decision, he would indeed seek immediate attention, but the last time he checked, Northside Middle School did not grant degrees in the medical disciplines to any of its pupils, and it would be to one of that institution's matriculants that he would turn for the treatment of any such priapriatic side-effect, again and again if necessary - or more correctly, again and again as necessary.

The pelvis of the very eighth-grader in question shuddered in vexation as Don continued to tease at her impatient mating organ.

"In..." was barely audible. A-ha!

"What was that, darling?"

"Do it." Louder, and clearer. A trace of a whimper. Excellent!

"Do what, sweetie? You're being so friendly this morning, I'm inclined to give you anything you want, but you're going to have to make yourself clear." Don was talking a good game, but he was struggling to hold himself back from taking the plunge his aching, overcharged cock demanded. Easy, he said to himself, make her ask for it.

"Please, Don...."

"Who?"

"Please, Daddy...." Thank the Good Lord for Dr. Cohen and his methods!

"That's better...please what?"

"In...put it in."

Don stifled a groan. Jesus was this hot! While not quite ready, per his plan, to yield fully, he did press forward slightly, parting the proffered mating mouth and allowing his penis' full head to rest within. This was hardly an act of solicitude, he was well aware -- this concession to Bethany's plea was primarily driven by his own lustful impatience.

Pleasure did indeed wash over him in result -- the wet, warm, vibrant hold the juvenile sex organ wrapped around his cockhead felt fantastic; an electric shudder ran up his spine, and again it took great self-control to refrain, even for a few moments longer, from further insertion.

The girl responded to his move with a long hissed "yesss", ending after a second or so with a whimper-like inflection of frustration. Don smiled as he watched the tight, gorgeous, heart-shaped ass before him wriggle and writhe, as his formerly resistant stepdaughter attempted to force her way back to engulf his entire cock on her own authority. Were it not for his now two-handed hold upon her narrow waist, she would have easily succeeded. He shuddered once more in pleasure, gritted his teeth, and continued with his game-plan.

"Tell me what you want, Baby."

"I want it." Don didn't know where to focus his eyes - at the girl's blushing face, in profile, or at the cute little anus winking as him as she squirmed.

"Tell me what you want, like a good girl. Tell Daddy."

"I want...I want it...your cock....inside me...."

"Mmm, that does sound like a good girl--" Don's vocal and pelvic control were challenged at this instant as his stepdaughter's agile vagina made a worthy gambit for more of his cock, and almost succeeded.

"Easy there, Sweetheart. I'm just trying to make sure I understand. You want me to fuck you?"

"Yes."

"You WANT me to fuck you...you want our own stepfather's cock to fuck your slutty little pussy?"

"Pleeeease...just...please."

"I don't know, Honey, remember you used to pretend to hate it; I think I need you to say clearly what it is you want." All this from Don was a struggle, and he could tell that some hint of this leaked into the timbre of his voice. His glib, cocksure arrogance, a standard feature of his every communication with Bethany over the past few months, was on the verge of cracking under the trial of holding himself out of the heavenly girl.

"Don...Daddy...please fuck me, I need it, I want it, I always wanted it....fuck me..."

That was good enough, and it had to be, because Don could not hold back another heartbeat.

With a blurted "Oh, good girl," he drove forward, delighting as each millimeter of his shaft was quickly consumed by the girl's quivering sleeve. It was an amazing sensation, so wet and heated, practically sucking him in, offering no resistance whatsoever and yet wrapping him with a vaginal grip of profound strength. Don's penis felt so good in that moment that he might have considered the pleasurable state better than an actual orgasm.

Having sunk to his depth, his taut scrotum pressed up into his stepdaughter's pelvic bone, hard against her youthful clitoris. He pressed in even further, feeling his sac stretch, not unpleasantly, his tip finding her inner limit after glancing across the firmer nub of her cervix. This brought a sweet grunt from below.

"You like that, Bets?"

"Uh-huh."

"What do you like, tell Daddy."

"Ooh, I like you in me, I like your cock, I love your cock."

Don smiled in lust and self-regard as he slowly withdrew. Her underaged cunt clutched at his retreating shaft in protest, a delicious feeling.

"Whose pussy is this?"

"Ughn, yours...Daddy, my pussy belongs to you, Daddy."

"That's right, that's a good girl," as he drove forward again, slowly and completely. "This pussy is mine. Who decides what happens to this pussy?"

"You do, Daddy."

Another withdrawal, this time almost to the point of vacating his just-confirmed possession.

"And is that for my good, or yours?"

"It's for my good, Daddy -- I want you to own my pussy."

A final "good girl" and Don was done with the sex talk, as important as that can be, because it was time to get serious about fucking this incredible fourteen-year old. He slammed into her without warning, pulled back at a more moderate pace, and then slammed in again. He knew that after this round alone his balls would be bruised, although he felt no discomfort in real time as they violently collided with the girl's crotch.

In and out, again and again, the girl crooning unintelligibly beneath as he pounded away at her upturned cunt. His brain grew hazy, his focus narrowed, zeroing on that sweet ass, on her narrow waist, on his thick cock as it slid in and out of her stretched sex, feeling impossibly hard, impossibly large, impossible to ever stop -

And then his fourteen year old stepdaughter - a victim of months of sexual battery and incestuous abuse, a beneficiary of weeks of diligent treatment by one of the world's foremost authorities on the biofeedback conditioning of adolescent females, and an abstainer from all sexual congress for a full five days -- climaxed.

A gasp, or a shriek, more like a combination of both came from her core, and Don felt the not-fully-mature vagina clamp down on him with amazing, rippling strength. In response, he hastened his pace, vowing to long-stroke the youngster through this orgasm, the first of the day and the first she had ever openly asked for.

"Godgodgodgodfuckfuckfuckfuck..." rang out of the adolescent throat and he did his level best to hammer the adorable little bitch to glory, managing a steady speed, a full cycle length, and a merciless thrust on each in-stroke. He felt rather noble in his effort, as it was none too easy to keep matters steady - or even inserted - the way the vixen jerked and shuddered. But at last she eased in her throes a bit, calmed down, visibly relaxed, her spine again inverting into its graceful, cat-like arch.

Don kept stroking, taking in the vivid flush of her skin, and imagined he might ease off for now and try to build her up for a second peak, but this was a delusion put to rest when his lower body took over and drove him in to the hilt before his conscious mind even knew what was happening.

There was no holding back, he was coming himself, and so deep in he plunged, pulling her back into his penetration by the powerful grasp he still had around her waist, finding purchase on her prominent hip bones. His buried penis exploded in delight and release, gouts of cum thundering up from the base of his shaft and pulsing through him and out, firing his seed into the very center of his fourteen-year-old stepdaughter's receptive genitals. Five or six full-strength pulses wracked his balls and shot through his length and into her. Hearing her mutter an "Oh God, yes'' as she sensed his semen filling her made it absolutely perfect.

-o0o-

By seven p.m., Don was ready to pass out from exhaustion. Abed, eyes half closed. This was really only the third break they'd taken during their day-long sexual reunion. He was finally done - there was no way he'd rise to service again without a good night's sleep.

After that morning's initial doggie-style power-fuck, he had experienced virtually no refractory period, either physically or psychologically, remaining both hard and eager. Perhaps this unusual experience was attributable to the double-dose of unneeded Viagra he'd taken, or to the degree of hunger for Bethany he'd built up during their hiatus. In any case, neither his will nor his power abated much, so he had simply told the girl to sit up on the bed and clean his cock thoroughly with her mouth, a duty to which she was of course quite accustomed but which she undertook on this day with a never-before exhibited enthusiasm.

Whatever minor and temporary post-orgasmic debility he had suffered was quickly discharged by the feel of her soft and practiced mouth sucking traces of semen and girl-goo from his still-firm prick, and by the sight of her lovely face eagerly at the task. He hadn't focused much on her visage in their just-finished first bout, so its central role in the current activity assisted as well, by providing fresh libidinal stimulation.

Bethany was a real beauty, and she apparently knew very well that cocks are sucked with eyes as much as they are with mouths. With their aspect of wide-open approval-seeking, they made her stepfather groan in need, and it wasn't more than a matter of three minutes before he found himself gently pushing the girl back onto the duvet and entering her vagina, this time face to face.

But that was hours ago, now. His balls ached now with a half-dozen drainings, his shaft was chafed from literally hours of prolonged vaginal servicing, his glans was sore and painfully sensitive to the touch. He was done, now, for sure.

His fingertips traced Bethany's lower spine as she lay beside him, her head upon his chest and her own fingertips lazily raking through his trimmed pubic hair.

Six times in one day - that was a record for Don, or more accurately his record performance for many, many years now. He'd occasionally had such heroic showings during his long-past college days, and he was pretty sure his all-time record was eight, but he had been twenty then and those orgasms and re-ignitions had been parceled out among three different girls. Strange pussy not only gets you up for it, but makes you horny again for the familiar pussy, as well. So today was definitely Don's lifetime achievement award for number of times in a single pussy. And what a spectacular pussy it was!

After their third go that morning they'd taken a break, and he had actually iced his balls during the lunch they ate together. Even then he's been noting the difference her biofeedback conditioning had brought about in the experience of sex, not just on her but also for him. While he had always taken delight in seizing or coercing his pleasures from the reluctant and resisting teen, Bethany's newly acquired enthusiasm for both him and his cock made matters a whole new ballgame. For instance, after lunch, while he watched the last five innings of an actual ballgame, it had been completely on her own initiative that his now "cured" stepdaughter had decided to gently suck on him, nursing at his penis for over ninety minutes before, to her visible surprise, instead of his usual finishing strategy of a black-out threatening throat fuck, he invited her to mount up "reverse cowgirl" and finish him off that way.

Granted, this was primarily due to Dr. Cohen's advice that, on this breakthrough day, Bethany should receive every load Don had to offer within her now-fixated vagina, saying something about "final imprinting." And Don had no delusions that he would not continue, in future, to often put his stepdaughter's well-being in the mild and temporary danger that his selfish airway commandeering occasioned. But on this day, and with the novelty of Bethany's proactive sexual service, he actually wanted to reserve his spend for her womb, exclusively.

His need for a recovery period lengthened with every round, and so after the cowgirl ride it wasn't until another hour or so had passed before he pulled himself away from his rest-and-recharge activity (viewing online porn of a decidedly youthful genre), sought the girl out, found her actually studying in her bedroom, bless her heart, and fucked her up against the wall.

He had at that point actually thought that would be it, and so he had gone out to his workshop for real, just to clear his head, which ached mildly from too many orgasms in one day, and to move around some workpieces in order to support his cover story, should his wife, against all precedent, even check into the space. Having gotten a little dirty, and feeling that layer of overall "meh" which a day of non-stop fucking can cause to accumulate on one's body, Don had decided to take a quick shower.

He failed in this, because it wasn't quick. His intent was soon thwarted by the unexpected arrival of a shower mate, and after a great deal of soaping and poking they had ended up here, on the master bed, still wet and dripping and reversing that reverse cowgirl from earlier into a cowgirl better affording fatherly tit-torment throughout the homestretch of the girl's bucking ride.

So now, after six testicular evacuations, Don knew he was truly done for the day.

"Bets, this has been some day, hasn't it?"

"Yes, Daddy. A really good day."

They rested in silence for a time, and then the eighth grader sounded rather somber.

"I'm so, so sorry, Daddy. I really am."

"Whatever for, sweetheart?"

"For being such a bitch before. I can't believe I acted like I did. I gave you so much trouble. I gave this big fella so much resistance. I was awful."

"There, there, Bets, don't worry about that. I'm glad you see the light now, but I really didn't mind forcing you. In fact, I'll probably pretend to force you, from time to time, just for the fun of it."

"Good...I like that...being forced. But I also like...you know...serving you, serving him."

"Easy there baby, `he's a little sore, and plenty worn out. But I'm proud of you...that floppy cock you're playing with is proud of you. You don't know what an achievement it is to make a cock come six times in one day, and I put that all to you...both to your efforts and to how fucking much of a total hottie you are, Hon."

"Really, I'm that much of a hottie, you think?"

"No, I know. But I think you're pumping a dry well there now, baby. Six is as much as I can do in one day at my age."

"But Mom won't be home for hours still, Daddy. I just know you can go at least one more time."

"I doubt it, but let me catch you alone tomorrow and I'll give you what-for."

"Can I at least try?"

"Sure, if you can get me hard after all we've already done, I'll throw you the bone." Don smiled. He enjoyed the tone of their interaction now - playful, friendly, friends. Not so much to say he appreciated the relationship as much as the ass, but still.

"Hmm, let me see...."

Bethany hopped up and retrieved the remote from atop her parents' bedroom TV. Then she climbed back onto bed, and rested her head against his abdomen. Don felt her mouth envelope his soft cockhead and ever-so-gently nibble and suck at it. Not likely, he thought, but she was definitely a good girl for trying.

Without pausing in her oral efforts, Bethany flipped through channels, then called up the onscreen guide and ran through the listings. Don was wondering what she had in mind when she suddenly selected something, stopped her sucking and said "this should work, Daddy - ten straight Zendaya music videos. Look at her and imagine my mouth is hers..."

Bethany had always been a clever girl. Four videos in - halfway through "Swag it Out", in fact, Don was rock hard for the seventh time, and he quickly shooed the girl up into the same ass-up posture with which had had begun their day.

Don was very pleased with Bethany, and with the day in sum. The experience had tempered his feelings, and brought more tender sentiments and affection for her to the fore. He realized he felt more for her than if she were just a delectable piece of high quality teen ass...More than just that. But she also was that. And Don was still Don. So as he sank into the delicious sleeve of Bethany's perfect pussy, he remained focused on the TV screen; and when, after two and a half videos' worth of savage fucking, he finally came with a dry, but intense, release, it was, in that moment, not his newly-loving stepdaughter, but rather the gorgeous, mononymmed, bi-racial, triple threat Zendaya that he "came to".

EJH 4/25/2017 Good girl - I am sure she will not regret this change of heart. Mind you, in my experience, resistance often makes the heart grow fonder...or makes the fond grow harder.
She offered her honor, he honored her offer, so all day long it was on her and off her.
