I love the idea of sisters getting it on with each other."We uncoupled, and Ellen gladly went to play with her sister. Brite sat down and spread herse...f between Terry and me, the way Ellen had only a few moments earlier – naked with a leg over each of ours, her pussy spread wide to the world, and her breasts eager in anticipation. We pelted her with kisses – the wet, sloppy kind with lots of tongue. Brite's large breasts got pawed repeatedly, and we could tell she loved the attention.Brite. I saw that she was suffering badly. She winced at every movement."Easy, easy!" shouted the doctor.They continued working, but much more slowly and cautiously than before. Soon the stockinet covered her right leg too. Then the nurses moved aside. The doctor smoothed a crease on the white cloth. When he was satisfied he wrapped Casey's legs with wadding. After that he dipped a plaster bandage into the water and squeezed it. The red haired nurse was supporting the girl's leg as the doctor was. It took a few minutes for any of us to muster the words and I handed her some drink to refresh and she slowly turned her head in my direction and smiled sweetly, “Wow Mr Frank, that was just WOW!” she sighed softly as I sat down beside her running my hands down her back to get the blood circulating again and it wasn’t long before she was able to turn herself around still amazed at what had just occurred. Her eyes were wide and her smile was permanent as she stuttered something to me which. There were small rivulets of sweat running between her breasts down over her taut stomach to her mound. Her hips were moving side to side making her pussy wink at me. As it got brighter outside, she looked up at my house. She saw me watching her. Instead of covering up and running away she smiled and waved. I waved back. She kept on exercising for a little bit. When she finished she stepped up to the window and did a slow turn so I could check out her body. She pushed up her tits presenting.
