Went to a highschool gathering organised by my closest bro at his house. I reached earlier during that time and was greeted by his elder sister telling me to come in while waiting for my bro to change his clothes. She looks 85% similar to Song Ji-Hyo but with a mature attitude, during highschool times she will sometimes come to my class just to pass some learning materials to my bro and that is when everyone in the class will turn their heads to her.

She invited me to sit on one of the sofa while she sat on another which is 90 degrees to my right. She was stunning as usual and today she's wearing a plain T with a short denim skirt. Although She sat with her legs side by side and closed tight, the top part of the tight skirt is flat which , if looked directly from the front you can look into her triangle. However I was sitting diagonal to her and the angle was almost but not good enough to peep into it, I couldn't just get up and look since it will be too obvious.

After a few minutes, my bro came out of his room after showering and sat beside his sis while greeting me. My bro was showing his sis our pics in highschool and that is when I decided to go to the toilet although I did not have an urge to pee! His sis was too focused on looking at my bro's hp and that is when I got up slowly and looked directly in between her legs and Voila, a pair of innocent white panties!

My heart was beating very fast and I stayed in the toilet for 30secs without doing anything, hoping to see it again when I return later. However when I got back they were looking at me and I couldn't just peep at it again otherwise it would be too obvious.

More experiences to come!
