Upskirt for grandpa

I've had a huge crush on my grandpa for a year now and never known how to get him to like me. So I asked advice here and acted on it.
I went over to his house wearing little clothing, a skirt and a tanktop. Since he lives alone he always needs help with chores. He needed some help with getting a box from a shelf, which required a ladder.
Being the good granddaughter I am, I climbed the ladder for him to get the box. That way he could easily look up my skirt. I made sure to take my time getting the box to give grandpa a good view. I could feel his eyes roaming my ass, studying my white panties.
After I got the box and went down again he thanked and things went back to normal for the most part. But I know he likes me too now, he could not stop staring and even brushed his hand against my butt a couple of times.
