Amity tried to smile at Gramps but only succeeded in staring at the floor. Unconsciously, she tucked in her pink T-shirt, accentuating her full bosom.
Gramps looked appreciatively at Amity. Oh, what a glorious rack she has. But then he tried to be stern, and waved the errant math exam at Amity. "We talked about this, didn't we, dear.?"
"Y-yes, Gramps." A tear rolled down Amity's plump cheek.
She was quite a cutie, but she'd certainly put on the "freshman fifteen" and then more as a sophomore and now a junior.
Amity had asked Gramps, since she was now out of community college, to help her with the expenses at Buttermilk State, and feeling badly for the orphan, Gramps had.
Ah but he'd observed succinctly that her community college work had not been up to par. At twenty, Amity needed to pull it together! And they'd struck up a bargain.
"Gramps, I tried so hard." Amity smiled. She'd glossed her lips and touched up her eye makeup to appeal to Gramps's soft heart. She knew Gramps liked her a LOT. Most of the family was fairly bookish and homely.
However, Amity had been adopted, and as it was said in the book "Freakanomics" usually smart people were childless and adoptees of blue collar stock; gorgeous maybe, but not particularly bright.
Amity's adoptive parents had given up on her, and cast her out after finding her passed out over the toilet with a needle in her arm, and Gramps had gotten her clean and now was working on making her an academic, though this was a chore.
"Your parents believed in using psychology as a discipline, and we know how well that worked out, didn't we, Amity?" Gramps asked acerbically.
"Y-yes, sir." Gramps often slapped Amity if she forgot to call him "Sir" and since moving in, she'd gotten better at showing respect.
"So about this paper-"
"I studied for over an hour for this exam, Gramps, I really did!"
"I believe you, sweetheart." Gramps responded soothingly.
He watched in some satisfaction as her fingers bunched and she trembled more. Gramps ached to whip Amity's breasts. Such full, pink, naked, heaving things, those tits were.
Gramps's second wife, Clairdyce had been a committed submissive of sorts. She'd been rail thin with curly salt-and-pepper hair.
Clair would often provoke Gramps into using his belt on her adorable, cupcake mammaries until she'd cried, and then manically blown Gramps...
But using his belt on these glorious breasts of his adopted granddaughter, big, full things that ignored gravity and ballooned right out there.
"But trying really isn't enough to pass your coursework sometimes, even if you are somewhat of a air-headed sociology major."
Amity sighed, and her boobs bounced, hypnotizing Gramps readily. "All my brothers and sisters hardly studied at all, and they made straight A's."
"That's not really true." Gramps said, although one of his "natural" grandsons, potheaded Michael, did mental algebra and wrote his term papers on the school bus. He had attended class about twice a year and had made it into the National Honor Society.
Gramps thought about trying to explain about how Amity had a different genetic make-up, and would have to work harder than her natural born Mathlete sibs, but he knew all she'd really understand was the strap.
After all, Amity had been far more popular in high school than her brothers and sisters, in the one they'd attended together, and she'd shone socially if not scholastically in the ones she'd gone to after being expelled from the first.
"You spend too many late nights out, and not enough studying, right?" Gramps asked gently.
Amity had been asked to live off campus after her bong had exploded and burned down the Kappa house. So now she lived at home with Gramps, and he watched her hours carefully.
"And you can't seem to give up your loser, with the steel guitar, you can't stay out of his chopper side-car, can you?"
Gramps's dick was about to pop out of his overalls as he thought about her screams, after his right arm began its familiar exercise. Soon, soon...
Gramps stood up from behind his desk, he leaned over and pinched Amity's left nipple through her shirt, HARD.
"Answer me! You're a lazy little good-for-nothing, aren't you?"
"Y-yes sir." Amity felt her panties getting wet. This always happened when Gramps admonished her. All her life her parents (until they ejected her) had told her she was "Special" with "unique gifts" many boyfriends had showered her with compliments and gifts, her English teacher (who she'd fucked, and then blackmailed) had told her she was a Goddess...
