I had this idea for us to tell our sex stories but with a twist.
Describe a particularly memorable and kinky sex act that you've had, but when you tell the story tell it from a third person perspective (as if describing what someone else is doing) and use the names of the two posters before you for the people in your story (obviously whoever goes second will only have my name to use so just change your own - the third person will then use my name and the name of the second poster).
I'll kick it off with something that happened to me...
Chris slowly and gently tied her hands with the silk ribbon. Lynn had never been tied up before but immediately she knew she was going to enjoy it. Chris lead the naked girl to the side of the bed and swung her around, pushing Lynn's face down onto the sheets - her ass left invitingly pert and ready infront of his hard cock. Chris didn't wait, knowing she was ready by the glistening trail of wetness running down her leg. His cock slid into her with ease and what followed was the most intense sex Lynn's petite little frame had ever experienced.
