18 year old May's grandpa often loses his temper for no reason after he came down with senile dementia. She discovers that the only way to calm him down is to let him see her naked - but this time, he insists that she fuck her Daddy in front of him. Willing to do anything to keep Grandpa quiet, May obliges, secretly enjoying her Daddy more than she anticipated.
"Go away, Daddy," I said with a sigh. "Grandpa and I need some time together." Daddy knew what I was doing, but he had never actually watched me flash my Grandpa.
"No," Grandpa growled. He gestured for my father to sit.
Daddy looked at me. "It seems he wants me to stay." Daddy looked excited.
"Whatever makes him shut up," I said, shrugging.
I straddled Grandpa and gyrated my hips over his lap as I slowly lifted my shirt over my head. My tits popped out into Grandpa's face, and he reached both hands out to roughly grope me. I pretended to moan and love it while I grinded my crotch against Grandpa's lap.
I heard Daddy gasp behind me.
