Sex at 40 - part 3 Maria wore a long, loose skirt, and she had to lift it to sit astride the Sybian. She held the control box and settled herself into the seat, and Kathleen realized that the white protuberance must be pressing against the folds of Maria's vaginal lips through her underwear. "Peter has to travel a lot for his work," Maria explained. "He bought me this to keep me happy while he's away." She activated the machine, and a deep, low rumbling sound filled the air. Maria pressed herself down onto the machine and gasped. Kathleen was at once fascinated and embarrassed. She could feel the floor shaking and sense the change in frequency when Maria turned the dial to increase the speed a little. Maria smiled up at her. "You just have to try this. It's like you wouldn't believe." Kathleen settled onto the bed to watch. The gin had quickly soaked into her system and her inhibitions were dropping away, like leaves in fall. "You go first," she said. "Show me what to do." Maria gave a groan of need. "O.K.," she agreed. Kathleen could see that her new friend was basking in pleasure as the machine worked its magic on her. "Did you really see a plastic surgeon today?" "Yep," Kathleen answered. "I always promised myself a 36C cup. Now I'm gonna have it." "You don't need to change," Maria warned, closing her eyes for a moment against the fierce buzzing of the Sybian. "Never said I needed to. I want to. I just want to be big, like you." Maria was panting now. "Like me?" she said, between gasps. "You're kidding. Help me out of this dress and take a look. I'm not as big as you are." At first, Kathleen was not sure if the invitation was genuine so, rather nervously, she moved behind the woman, unzipped her dress, and pulled it carefully over her head, revealing Maria's magnificent body, clad in nothing but her underwear. Maria reached behind her own back and unhooked her bra, allowing her breasts to slip free. "See," Maria emphasized. "You're at least as big as me." She gave a long groan. "Shit. I'm going to come. Do you mind?" "Of course not," Kathleen assured her although, in truth, the whole thing struck her as a little strange. She had never seen another woman climax, and the possibility both frightened her and excited her. She did her best to offer a relaxed smile. "Do it. I want to watch," she said. Maria needed no further urging. She closed her eyes and held her breath and it became clear that she was trying hard to bring on her orgasm. It arrived quickly and she made a great deal of noise, gasping as it approached, crying when it arrived, and then sobbing in the aftermath, quickly turning the dial to reduce the intensity of the vibrations as soon as the moment of truth was upon her. It looked better than the best orgasm Kathleen had ever imagined, and she felt enormously envious. "I want to try," she said. Maria climbed shakily off the seat and moved behind her guest and began to undress her. It's best if you're naked, she advised. She removed Kathleen's blouse, and then her skirt, and then, surprisingly, pulled off her underclothes, too. When Kathleen started to protest, she hushed her, soothingly. "It's O.K.," she said. "Trust me." "What if your husband arrives," Kathleen protested. "I don't want this to be the first impression I make." Maria laughed. "Oh, he'd love it if this were the first impression you made." As if on cue, the telephone rang. Maria waited for the caller ID to appear and then snatched up the handset. "Hiya," she said, brightly. There was a pause while she listened, and then her tone changed. "Oh, O.K." Another pause. "No, really. Don't worry." Again, she listened. "I'm with Kathy, the girl who moved in next door. Don't worry." She said her goodbyes and hung up the receiver. "Peter's stuck at the office. He'll be there until nine o'clock, at least." She settled on the bed. "Now. We have hours of privacy. Don't waste them." Kathleen smiled. "Show me again. How do I turn this thing on?" Maria turned the dial and a shock of pleasure ran through Kathleen's body. It was stronger than any sensation she had ever felt, powerful and irresistible. The first orgasm was on her before she even knew what was happening. The second followed close behind. After that, her body grew more accustomed to the punishment, but she slipped into a dreamworld, she no longer knew where she was. She reached blindly for the control box but she could not find it, so she rode the machine, grateful when she felt Maria kneel before her and grasp her in strong, comforting arms.
