You know, I was awake last night after we went to bed. I totally knew that you were jerking off next to me thinking that I was out. Its a little bit weird that you were jerking off next to your step-sister, but...what was that thing you did at the end? were you eating your own cum?! I have to admit it got me horny too listening to my step-brother beat his meat.... I wanted to touch myself so bad listening to you slurp up every last drop. How about this, how about we cum together and you let me tell you how to eat it while I vibe my pussy. Lets hurry tho before step-mom and step-dad get home!!
