My parents were away and my sister and I used that as an opportunity for some much needed freedom. We both thew parties with our respective friends and threw a big one for everyone. We ate exclusively take out. It wqs been great.

She also used it for some much needed alone time with her boyfriend.

I want to say straight away that I'm not like this. I'm not some pervert or creep. I'm not some incestuous dude who wants to fuck my own sister.

But our rooms share a wall. I can hear everything. At first I tried to block it out, I thought it was disgusting, but like some kind of exposure therapy, night after night, hour after hour, it started to get to me. I tried to tell myself that getting horny wasn't connected to it, then that hearing sex like that must just be some kind of natural aphrodisiac and it's not my fault.

But by the time I was spending hours jerking off with my ear pressed to the wall it became undeniable that I need to confess: I'm addicted to the sound of my sister getting railed.
