GRANDPA'S GIRLS
It was about 7:30 a.m. when Grandpa Sam woke to a now-familiar sensation at his waist.
"Hunhh, I, what?" the startled old man grumbled, but soon luxuriated in the feel of a soft suckling mouth on his erect prick, before gazing sleepy-eyed down his torso as his rock-hard cock disappeared between the stretched lips of his brainy teenage granddaughter Allison.
"Allie-cat! Ahhh, ohh, jeez, you too?" the old man moaned aloud his older granddaughter's pet name, before surrendering to the glorious feel of her velvety mouth as she worked his pole with a skill he had no idea she possessed.
Allison stared nervously at Grandpa Sam's surprised reaction with the top half of his expansive crown encircled by her full lips while suctioning gently on the tip of his swollen gland. She didn't know quite what to expect when her grandfather awoke and was trusting on Brit's promise he'd be okay rousing to his big-titted granddaughter sucking his cock.
Minutes earlier, the bashful science prodigy had reluctantly entered the den on tip-toes, miserable about taking on the contemptible task assigned by her demanding brother, but also not wanting to wake her snoring grandfather prematurely and ruin David's plan.
Grandpa Sam's rough demeanor had always intimidated the meek girl, although she knew he loved her just as much as his other grandchildren. Still, she was petrified at the possibility of him exploding in a fit of rage and disgust at waking to the unthinkably forbidden act of his 19-year-old granddaughter giving him a blowjob.
Knowing what was expected, the well-endowed girl peeled her green cotton muscle shirt over her head to stand uncomfortably naked in the presence of the snoozing old man.
Allison suspected her grandpa had checked out her generous rack surreptitiously on previous visits, at least ever since puberty, when her prodigious chest had expanded practically overnight. The mindful girl also knew he was too respectful of his granddaughter to be obvious.
The wise coed reasonably assumed having Grandpa Sam wake to her kneeling naked with her large tits on full display attentively sucking him off would appease whatever angst he might feel at the outrageous act. She understood the importance of easing the chauvinistic old soldier's transition into the depraved world of her calculating brother's debauched sex lair.
Still, Allison felt awful, not that it mattered. David was relying on his constrained big sister to entice their old-fashioned grandpa with her abundant feminine charms to close the deal on his willing participation in the incestuous shenanigans of the Thornton household.
It was the miscreant youth's preferred plan, and considerably better than receiving harrowing grief from his tough grandpa for commandeering the lovely women of the family. David understood that to Sam, it was a woman's role to please a man - any man. Allison knew that was what her brother desired too, and she didn't dare interfere with it.
'Is this really happening?' Allison queried miserably as she unlatched the buttons on her sleeping grandpa's pajama bottoms. 'I mean, this is my grandfather.'
The reality of her nightmare was made apparent when the old man's flaccid cock plopped from within the baggy pajamas, draping limply over a hairy wrinkled sack holding two rather large egg-sized testicles. The entire package was nestled in a dense growth of curly gray hair, with Sam's unaroused tool looking impressive, even when soft.
'Oh my!' Allison lamented internally at the alarming sight of her imposing grandfather's awe-inspiring meat, fearing its dimensions when it came roaring to life in the close confines of her pleasing mouth.
It was a vision a loving granddaughter was never meant to witness.
Unhappy, but certain of the necessity of performing the taboo act or risking David's wrath, Allison tentatively extended her index finger to make first contact with the limp staff, trailing her finger along the uneven veined surface of its fleshy length all the way to the deflated crown.
Gaining no response, she curiously took his listless tube by the tip to lift upright.
'Jeez, it's heavy,' she commented to herself on the substantial heft of the immense tool, before gliding her fingertips gingerly on either side of the ponderous shaft seeking to bring it to life.
"Ahhh," the surprised girl gasped when the sleeping giant cock suddenly twitched.
The reassuring reaction along with a rush of warm blood flowing into the inflating pole signaled her success as Allison's gentle fingers slid easily along its increasing span, aided by an occasional swipe of her thumb across the flaring tip of his expanding cockhead to smear the small drop of precum settled on the eye of the monster.
'It's just a cock,' Allison repeated her mantra, just as she had the first time she had blown her father, and desperately seeking to assuage her moral angst over 'waking' her slumbering grandfather.
The unfortunate coed obviously knew it wasn't 'just a cock' - it was her grandpa's cock. Nonetheless, the time had come, and it was a needed fabrication as she could no longer delay taking the old man's swelling prick into her unready mouth.
Circling her lips, Allison didn't bother simply running her tongue over Sam's purplish helmet. Instead, the naturally gifted lass opted to take his knob in whole to the broad rim and then swirl around the sensitive surface once or twice before working her way down the widening girth of the still only semi-hard shaft.
The skin of her grandpa's cockhead was remarkably supple and warm to her tongue, but Allison found her oval lips were already straining to encompass his fat crown even though he wasn't yet fully erect.
'There's no way I can take down all of grandpa's cock,' Allison knowingly assessed Sam's considerably thick staff with the same trepidation as Brit had unknowing done only hours earlier. 'He's not even completely hard yet.'
Still, Allison determined to do the best she could for fear of disappointing David, slipping down the swollen length to consume fully five inches of his growing rod, with the pulsing mushroom knob pushing to the entrance of her throat, but unable to punch through any further.
'I'd choke to death,' Allison realized astutely, although she'd previously demonstrated a natural ability for deep-throating David's equally impressive, but somewhat slimmer pole.
