You take it off and have a surprise.

You pull down your thin thong as your grandfather watches.

As always, you have no idea that your grandfather is really hard as you pull it down, being completely naked except for the high heels, which really doesn't count as a piece of clothing. At least not at this point.

"Thank you dear. You just are so...beautiful."

Your reply is "thank you" as usual. You can't help but feel a little strange for doing this, especially for your grandfather.

"Pull up your hair again sweety? Please?" he asks again in a gentle tone.

You do as his says and in moments, your eyes open in shock and you blush madly. His hand suddenly grabbed your ass, squeezing the flesh in his old hand.

"...Naomi you're sexy."

"G-Grandpa?" you mutter out.

He continues for a while and you're too much in shock to run away. He then quickly slips a finger in between your legs and plays between your legs.

You don't know quite what to do, but part of you seems to be enjoying this. Your beloved grandfather must have known this, otherwise you wouldn't have felt and heard this.

"Am I doing something you don't want...Naomi?" he says, as his finger begins pumping inside and out of you.
