I’m guessing an earth-shattering orgasm is just the ticket for a good night’s sleep I thought. I got out of bed and walked across the room. I slam...ed my fist down on the hated alarm clock. It’s Friday, the last day before our two week Christmas break.I then heard a soft knock at my door. I threw on a robe and went over to open it. Darcy stood there all made up and ready for school. I couldn’t help but notice the way Darcy’s eyes explored the folds of my robe.“Take it off, “ was all my sister. I know we are both on the brink of orgasms. I hear her moans growing in desperation and they are coming faster and faster she sounds like she is saying YES. ( God she knows what's she's doing to me.) I feel myself starting to cum, and I know she is there too, so I ram her as hard as I can. " AHHHHH I'm cumming", I groan and I know that she is so close, she starts jerking under me.

My hand pushed my flimsy dressing gown down mid thigh, but my flank facing him was exposed, as I was on my bare ass and the material was around it, I needed to rise up and let it down, but he was by my side before the thought of doing it entered my mind, I was in a classical caught moment, so I decided to brave it out.'Good morning darling', I said unabashed, noting he was staring at the expanse of bared flesh on show.I started to type again and he looked into the screen as I started writing,. Yet he knew that somehow, he had to fix it. No matter how hopeless their situation was, he just couldn’t walk away and pretend he didn’t feel anything for her, especially now, when she’d almost been snatched from his life.He shook his head as he headed for his truck, with his phone to his ear, filling in his partner Davey about what had just happened, and giving him their license plate so he could report it to the police. Of course he’d have to deal with talking to them and her father later,.
