Allison may have found her release under the surprisingly talented manipulations of her deviant little brother, but David wasn't satisfied.
His vanquished sister's performance left him in a state of arousal needing relief. He'd given his newly-shaven sister a body-rocking, explosive orgasm, and it was time for her to return the favor.
David intended to take advantage of his beleaguered college sister's debilitated condition, intuitively knowing his next demand would push Allison to a new level of degradation and moral repugnance.
It would also likely spark renewed resistance, and he wanted her as physically and emotionally weak as possible to minimize any intransigence.
"No rest for the weary, Allison," he advised. "There's more to do."
Allison's post-orgasm reverie was broken by her animated young brother's grip on her right forearm as he pulled her up, grabbing her by the left hip to lower her from the countertop.
A sick feeling overcame his aggrieved sister's soul as the reality of what just happened settled in, but David left no time for introspection and remorse about the perversion she had just endured.
"Get down. We're not done for today. Not yet." David's reference to 'today' was disconcerting, but under the circumstance, his depleted sister put it aside to focus on the issue at hand.
Allison's jelly-like legs couldn't support her weight in her enervated condition as her feet hit the tiled bathroom floor, and David's powerful hands on each shoulder easily forced her feeble knees to buckle.
She quickly found herself in a suggestive kneeling position on the linoleum before her reprobate brother, with her face arriving at crotch level. Nervous and distressed, the effect of her profoundly indecent performance was clear as she eyed warily the impression of his exuberant erection against his briefs.
"DON'T JUST STARE AT IT, ALLISON," David barked, returning to his gruff, commanding voice, and hoping his sister was still dazed and intimidated enough to simply follow his instructions.
"TAKE IT OUT!"
The scurrilous young man soon learned slightly more motivation was needed to achieve his evil goal, as Allison's sapphire blue eyes perked up with the demented gravity of the order, and her recognition of the depraved act he had in mind.
"N...NOOOOO...," Allison protested.
Just as he anticipated, the disturbing nature of his intent was enough for Allison to gain renewed resolve to not permit his plan, shaking her head strenuously, while her eyes shot darts of disdain into David's expectant glare.
"DAMN IT, ALLISON!" Her querulous brother yelled. "I DID YOU...NOW YOU'RE GONNA DO ME!"
David was pissed. In his fierce state of lust, he was in no mood for recalcitrance by his crouching sister, and decided it was time to coerce her compliance.
Grabbing a clump of her curly brown hair, he viciously pulled her head to focus her terrified eyes on his sturdy cock. The forceful move scared the vitriol from her appalled gaze...replaced by the fear of his perverse intention.
"THIS IS YOUR FAULT, ALLISON," David explained. "YOU MADE IT HARD, NOW YOU'RE GONNA TAKE CARE OF IT!"
After a brief pause of inaction by his petrified sister, David was running out of patience.
"I'M NOT GOING TO TELL YOU AGAIN, ALLISON," he bellowed, his need to cum driving his lurid demands of his sister. "TAKE IT OUT!"
Tears wet the reddened eyes of his frightened big sister as she cast a pleading look to David's scowling face, silently begging him not to proceed.
"N...nooo...," she stammered in fright.
Allison's head shook with her refusal, but David knew from experience it wouldn't last, even with her knowledge of the obscenely taboo act he expected. He understood his unrelenting threats, and Allison's dispirited psyche, would result in her inevitable resignation to her plight.
Meekly returning her attention to the disquieting sight of her nefarious brother's strong erection, the bullied physics major hesitantly lifted her hands to the elastic waistband of his briefs to reluctantly tug on the white cotton fabric.
When the bulbous purple head of her brother's hard cock appeared, she drew a quick breath, then tenuously continued downward as the swollen length of the veined shaft showed itself. With one more tug, she warily released David's hairy scrotum as his entire manhood sprang into view.
"Ohhhhh, I can't...," a hushed gasp escaped her open lips.
Allison had never truly seen a man's 'package' so closely, despite losing her virginity to Larry 'whatever-his-last-name' at science camp the summer after her high school graduation. In that fumbling event it had been dark, and she had barely touched the young man's penis before he introduced it to her vagina and took her maidenhead.
'Ulp...,' Allison gulped in fear at the possibilities coursing David's debauched mind with her little brother's rigid cock rearing only inches from her face.
The frightened coed dutifully lowered his shorts past his knees to where they fell on their own to the ground. David's straining pole pointed straight out from his pelvis, throbbing visibly in response to the blood pulsing in anticipation of Allison satisfying his all-consuming lust.
David watched with keen interest every move and expression his shallow-breathing sister made while kneeling completely naked in submission before him.
Allison's sizable tits barely stirred, and her bare cunt remained shiny with the slick combination of baby oil and her own viscous pussy juices from her unseemly sexual performance at the hands of her brother.
"Yes, Allison, you can...," David urged, his need so overwhelming he could think of nothing other than Allison providing the release he wanted so desperately. So far, he had done all the deviant touching of her helpless body.
Now, his cowering sister was expected to perform the same scandalous acts.
Hoping to keep her maniacal brother from verbally haranguing her again, and thinking she might forestall what she feared was his true intent, Allison raised her slim right hand to timidly touch the tender skin of his bobbing shaft.
"Ahhhhh, there you go, Allison...," David murmured in reaction to the unbelievably erotic sight of his sister's hand on his cock as Allison tentatively watched the fleshy pole jerk in response.
Initially backing off with uncertainty, Allison soon cautiously advanced, lightly pressing the pads of all five digits onto the inflamed skin to take the solid stalk between her fingers. She was very deliberate in her grip...afraid to squeeze too hard and incite his ire.
"Mmmmm...," David sighed, happy to stare in awe, while fixated on his sister's growing acceptance of her plight.
