You aren't prepared and gag immediately but I won't let you go an inch. You hands punch my sides and I pull out and slap hard again."Don't you ever fu...king strike me again"My cock is in your throat again. I hold it at the same point and you go to push away but you know better this time. I reward you good behavior by allowing you to breathe for a moment before I pull you to your feet by your throat. I walk you to the bedroom when there is a knock at your door, "answer it" You do as you are told. You then walk down a path simliar to mine and continue walking behind me, not together, as we both make our way to the liason point, deep in the trees, away from prying eyes. I am about 100 yards ahead of you, but i know you are behind me, and my cock begins to thicken in anticipation of it being gorged on by your eager mouth, and very soon too. I walk past the overgrown path that leads to what will some become our sex den, but i know that you are now taking that turning without needing to look. The door knocks...."i'll get it!" Said your younger energetic sister Audrey, Audrey was 19 and dressed to go college. It was always tough to loose that morning wood of yours at the sight of her. Audrey had black shiny shoulder length hair, and although her body was a little bit chubby, her breasts were an impressive 36F, youthful and full, she knew her tits turned heads and would readily display them in cleavage promoting tops."Who was that at the door Audrey?" Said mom, "Its a parcel for. She soon realised that it was my penis and quickly went bright red from embarrassment. I told her not to worry about it and that it felt good when she touched it. She sat on the bed and looked at me weird again, she asked me if I would tell anybody about what just happened. I told her no as it was probably bad for me if anybody found out too. We then both got into our beds and were silent for a bit. She then asked if I have ever touched myself to get that good feeling she gave me. I replied yes.
