I once found a pair of her dirty panties from the washing machine and took them to my room. I have used the panties many times to masturbate. At first... I felt very guilty masturbating to her panties but after I while I didn’t care anymore. One day when I came home from my friend’s house I had to go to the toilet so I headed there, and when I opened the door I saw something that I was not expecting.I saw my sister naked leaning against the shower wall, the shower was off and she had headphones. By now she had come around and had taken hold of my cock and was really sucking on it nice and hard. "You like that fuckin' cock?' I asked I got back a muffled "uh huh" as she kept on sucking on my cock. After another minute or two, "You like sucking on cocks don't you whore?" I asked as t I now started to squeeze her tits harder, twisting her nipples, Again she replied with a muffled "uh huh". Her moans were now louder as she devoured my cock. I let go of her tit and placing my hand on the. Or something. She flushed the toilet and made her way out into the hall where she realised that the noise of the toilet was going to be clearly audible in her uncle's office. As she passed the door, he had obviously composed himself and hidden the porn that he'd been looking at. He was watching as she made the doorway and Julie assumed that he'd been waiting to see who it was that had snuck past without him even realising that they'd been past the doorway."Oh, hi Julie ..." he said, his eyes. I pulled out of our drive. Looking in the rearview mirror, I saw that I was being followed by a tan or cream color car. "Britt, act like you're looking for something on the backseat. We're being followed. It's tan or cream and stays back."She did and came back up with a small nothing that she dropped on the front seat floor. She said, "Right. I see it. Should I call 9-1-1?" Let's wait a moment. I have an idea. It may flush whoever it is but it will verify that we are being followed." I turned.
