Her hand slipped down, and John found himself moving to assist her. Covering her small hand with his, he guided her unerringly to his excitedly pulsing rod. There was an instant when he felt her pulling back, but it was too late for him to let her stop now. She wanted to touch it, and by God, she was going to!!

"Oh!" she cried out, "Oh Gramps… it's… it's so big… I mean it's much bigger than I thought!" Awesome terror raced through her ten year old body and mind as she realized that her grandfather's heavy rod that at that moment twitched lewdly and hugely in her palm, was much larger than either of the two male penises that she had already seen… her father's and Uncle Ike's! It had never occurred to her that there would be so many different sizes… and the whole concept of it floored her. Not to mention the fact that she knew that it would never… never fit inside her! And, she had so hoped that it would!

John was hardly listening to his suddenly fearfully cringing young granddaughter as she began to protest. With one hand, he maintained her small fist about his veiny cock, with the other he continued the delightful exploration of the hotly quivering little pussy between her naked thighs. He worked up harder and higher into the tightly clenched little opening, moaning a little bit from time to time as it felt especially good to his proding finger. Little by little Nancy forgot her worry as the wickedly exciting sensations began to grow stronger in the depths of her hairless little cuntal opening. A seeping warmth was spreading from her womb to all her body. She began to cry out with delight as the advancing finger finally reached her cervix, and John began to tickle at the cushiony surface at the far end of his little granddaughter's baby tight pussy.
