Okay, so, my sister,is about to turn 17, and I'm about to turn 16. So we're almost the same age, but we're not twins. Ever since i was early early 15, my sister started to wear shorts. I've seen her in shorts, she's a soccer player, so it's not new to me. But, when she started to develop, i guess you can say that, an ass, she started wearing short shorts for pajamas. And I started to notice that she's been wearing less and less around me. Now, current days, all shes wearing is this boxer shorts for girls, that is really tight, so tight that if you put something under it, it will stay, and i know this because she puts her iPod under the part that barley covers her thighs. Its see through, too, so you can see her white underwear. And shes wearing a sports bra. No ones home, and shes sleeping, so i stared at her ass for 5 minutes and I've been attracted to her ass for so long. So newgrounds, what should I do?
