I was gonna take a before heading out with the boys but right before I was about to my sister Quinn came into the room. She told me she was having issues cause her BF keeps sending her dick pics while he is away in college. Quinn wants more than a cuddle, my sister wants to fuck me! I can not believe this is finally happening to me, I have always fantasized about this moment and now it is happening, I am gonna fuck my hot ass sister. But the second I am about to cum, our Dad comes walking in on us! We were caught!
