inceztum:

My Brother has a bad habit of not knocking before he goes through any door,  and today he just barged in on me when I was in the bathroom.  After I bitched at him I turned back to the mirror and went back to my hair.  Next thing I knew I felt him coming up close behind me and could feel the unmistakable feeling of his hard dick pressing into my back.  Well I’m not sure what came over me but feeling my own Brother’s hard cock pressed up against me turned me on much.  Not long after that his dick wasn’t pressed up against me anymore,  it was inside me…
