Ive never been able to help myself when it comes to my step sister... ever since she's started staying with us, I haven't been able to take my eyes off of her. She isn't the brightest crayon in the box... so I decided to use that to my advantage. Ive dreamt of the day where I could slip my cock in her mouth.... and I knew just the way to convince her. Luckily she agreed...and in fact I think she might have enjoyed herself... I just have a feeling this won't be the last time me and her find ourselves in the back of my car.
