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."
