This story contains sexual activity between a brother and his underage sister, if that's not your cup of tea you should probably turn around right now.
Here's Part 1 if you haven't read it yet.
I collapsed back into the couch, my mind awhirl, full of anxious thoughts describing all the ways this could ruin my life. How this could ruin my relationship with my sister, how my parents would kill me over this, how I could end up in prison (to say nothing of the sort of treatment people who got sent in for this sort of thing received). At that moment, I was sure my life was over and without my lust clouding my senses any more it was all I could do to quietly freak the fuck out.
