Today, I was playing with taku-chan and kou-kun at the station when a really tall ET sister walked by, so we followed her. The sister got on the train, so we got on the train too. The train was packed, and the sister's big ass was right in front of us, so we gave her a wedgie. The sister was angry, but for some reason she was writhing and making lewd noises. So we flipped up her skirt and exposed her panties. We played a lot of tricks on her lower body, and she ended up peeing herself, making it all messy. Then we took her to our secret base. Our big sister did a lot of nice things for us at the secret base.
