My sister is hot as f**k. Her and I have always had a little bit of sexual tension- maybe it was just in my head, but growing up we were always super competitive and used to butt heads over all kinds of stuff, and I always felt like we were just one provocative comment away from something happening.
A few days ago, my mom and dad left the house for a few hours to go visit some family friends- my sister and I stayed home and my parents said they would be back later that night. So it was just me and my sister, alone, all day, in our PJs, hanging out and bantering like we do. She was wearing a loose t-shirt, pajama pants, and these little fluffy Christmas socks our mom had bought her, and she invited me to put together a puzzle with her in the living room. I was horny as f**k and I knew it was now or never, so I decided it was finally time to put the moves on my sister- but first, I knew she had to be convinced that incest was morally permissible
