I started looking into her cleavage there was nothing much too amaze because i had seen it many time, but this time she noticed me. She asked me are y...u listening. She known i am looking at her boobs. I felt ashamed and i told her let us finish tis now; I’m not in a mood to study. She had a small smile and me what happened to your mood? Ok let’s gossip for some time till your mood comes back…. I replied no lets sleep. She told no i won’t leave you to sleep because a lot more portions yet to be. He looked down at me smiling and said, "Damn little sister, you have improved your skills! But now it is time for me to show you what I wish I had known back then." I could feel my heart fluttering and got up off the floor. I realized that I was excited to find out the things that he had learned since the last time we were together in his room.I led him into the bedroom. He told me to lay down on the bed near the edge and to spread my legs. I quickly did as he said as I wanted to know what he. I had told Ann to make Cathy feel comfortable and to be the one to initiate things between them and for a couple of minutes Ann talked to Cathy while she gently caressed her arm and then leg before she finally leaned over to Cathy and kissed her. This was to be the first time Cathy not only had kissed another woman, but her first wife swap as well. By now Ann had moved in closer to Cathy and raising her hand to her cheek, she caressed it and again moved in and kissed Cathy. Ed and I watched as. They were so perfect. She just cooed and smiled and never once tried to stop me as I felt her up.I turned her around and walked us across the room to her bed. I reached up and undid the bra she was wearing and slowly pulled it off her. Again she never tried to stop me. When I turned her back around, she had her hands across her chest covering herself up. I gently took her hands and pulled them away. She was incredible. Her tits were bigger than I had expected, firm and soft with perfect dark.
