I have been living with a step brother and step sister for the past 8 years, sharing the same room and shit. I have watched them both grow up so to speak. The brother is turning 14 this coming November and the sister is turning 18 this May. I saw her topless many times before and it never bothered me up until she turned 16. Now all I can think about is wanting to have my hands and sometimes my mouth over those young, fresh, teenage, high school boobs. I sometimes get a hard on just thinking about it. Tuesday evening or rather Wednesday morning at 2's side when I went to bed, I saw her one boob like looking at me. I was never going to get this chance ever again and I placed my battery into my phone and had to wait for 5 minutes for it to finish loading. After it was done loading, I took two pics of it. And now, I just want to fuck her so bad right now. As in get on, get in, get out... I'm her 22 year old step brother.
