" Nothing, David. Nothing at all."With sinking heart, it dawns on me. I understand."This may appear harsh, David, but that is my right and I have cons...idered carefully. Crossing this boundary now, at the very start of our journey, will put you firmly in your place and me in mine. And you will know just what to expect if you displease me."She raises an eyebrow, in a gesture I have learned means an answer is expected.But in her tone, something whispers to me, a nuance, an edge, a sense of slight. Susie had dinner with us and afterwards we all listened to some music before showering and going to bed.The rules were in bed by 9pm and lights out at 9:30 and Mum would come in and say goodnight.I was laying there reading my book when she whispered to me to have a look. She was laying on her side facing me and had her pants down and said have you seen one of these before. I said I hadn't and she came over to my bed and sat beside me and told me to touch it. I was a bit frightened but she took. Then she came down. As soon as I saw her I knew where this was going. She was wearing a short robe which must have been purchased at Victoria Secrets. The robe showed off her full figure. Her cleavage showed through the robe and her hips and thighs could not be missed. She came over and sat down on the couch and asked what are we watching? As I watched TV with her I realized I was the one looking at her now. She was actually catching me stare at her cleavage and thighs and she was. Then, Marty removed Julie's thong and bra exposing my sister's fantastic body. Now they were as completely naked as I was.Again they kissed. I saw their tongues licking and sucking and their hands roaming over each other. For only a moment I thought of Julie's ex-husband and how he had really missed out on something so unbelievable.While I watched, Julie turned around so she was facing Marty's feet and began to kiss and lick her way downward. When she got to Marty's pussy she let her tongue.
