My sister is older than I am by about 5 years and I used to hide in a few places so I could see her naked. We had a closet in the bathroom and the door had louvers in it, I would hide inside and watch her get ready for school in the mornings. Another good one was hiding under her bed and I could see pretty much her whole room in the mirror she had in the corner.

I used to wait for so long for her to come into her room sometimes so she would not suspect anything. One day during summer break she spotted me in her room and dragged me out asking what the hell I was doing under her bed. I told her that I like to spy on her and see her naked, she gasped and told me I was a little pervert. she started teasing me asking me if I beat off while watching her and she started getting very dirty with the insults. She was already sitting on top of me and started rubbing my pants asking me if I was all turned on now, she then spanked it a few times and I jumped a little from the pain.

She slid her hand down the front of my pants and started pulling on the head of my cock, I squirmed around but she held me down without a problem. She stroked on me until I came then wiped what got on her hand all over my shirt. She got up and laughed telling me that I was still a little pervert.
