.I'll be right back." I stood there, naked, with a rock hard erection as she came back into the room. "I went through the boxes of my daughter's old l...ngerie, and thought of you when I found this." She held a very slinky looking beige half slip which had a band of lace along the bottom which surounded a slit on one side. Connie (her daughter) left several of these when she left after college...would you like me to put it on for you?" With that, she pulled the t-shirt over her head exposing her. Understand?’ ‘I think so.’ She rolled on her side, the same position she had been in the night before. Except now there were no covers to hide her, the lights were on, she was completely naked. The Odalisque, that’s what she looked like, but with the correct number of vertebrae, and he kissed each one, all the way to the bottom of her spine. He placed his cock gingerly between her cheeks. ‘Gently,’ she muttered, ‘take it easy.’ ‘Pull your top knee up a little more.’ He watched in fascination. The white stuff didn't travel far because it struck her in the face. The next contraction didn't produce much semen, or the next, and that's when he collapsed back to his bed.Normally, he'd lie relaxed and concentrate on the fluttering sensations of a dying orgasm, but this time his eyes studied his beautiful sister, the girl who'd just given him the best climax he'd ever experienced. It wasn't the best because it had been the most powerful or most intense or longest lasting. It was the best. "Save THAT energy for tonight" Kelly really was going to share her man with me. And I was going to let it happen!!The rest of the day and evening were a blur. It was our six month anniversary (not a big deal at all to me) and Tom, my boyfriend, gave me a cheap but cute diamond necklace as we walked to the boat show. Kelly was working the show as a model. We acted as if we didn't know each other and Kelly offered me a job interview with her boss, the owner of the boat company she was.
