Grandma was tucked up in bed, duvet pulled up, woolly hat on her head.

"Come closer, dear,” she said.

Getting to the bed, I said, “Grandma, what big eyes you have.”

“All the better to seduce you with, darling."

“What big teeth you have,” said I, when she licked her lips.

“All the better to eat your sweet plump rump, my dear.”

Blushing further when she said, “My what big nipples too.”

“Oh my!“ I exclaimed when I saw Grandma's duvet tent.

Grandma smiled lasciviously and said, “All the better to fuck you with.”

"You're not Grandma!"  "You're the mailman!"
