Clara was not thinking about how she had inadvertently changed all the women in the entire world. She was also not the faintest bit concerned that she had knocked the chronivac onto the floor, where it lay with a black and cracked screen.
Her eyes were closed, mostly because she was too afraid to open them. Still, she couldn't be in total denial because she no longer felt a significant weight where her arms and legs had been. Finally, she opened her eyes and turned her head to look at Jeff. His mouth was slightly open. His eyes staring at her blankly. The way her head even struck her as odd, something about her center of mass was decidedly different.
She heard a faint clicking sound way too close for comfort. Curiosity overcame her and she looked down to see what she had become (or in fact always was since birth.)
Along each of her sides she saw about a dozen insectoid feet, each of them 6-8 inches long with a couple joints that reminded her of her fingers (or the fingers she used to have.) They encircled her, with 2 just below her on either side of her pussy pointing upwards. Her abdomen looked faintly pot-bellied, but she wasn't sure if that was from her slouched position on the chair or just automatic physiological changed to accommodate her new form.
A few seconds passed and she experimentally twitched a few of her legs. They bent with slight, but audible clicks. She continued absent mindly moving a few more, and by reflex a wave of moment down her side. Clara though to herself that she should have been horrified, not sure herself why she hadn't fainted. Somehow these changes were much more comfortable than alien.
Jeff walked over mesmerized and touched one of the legs, seeing it retract suddenly. "Hey, aren't you going to say anything!", she said. A few second of silence. "It's actually not so bad.....", she said flexing her legs a little more confidently, "I mean definitely an accident!....I'm not a weirdo.......I don't...."
"Of course not! I think you are still...", he wanted to say beautiful. Instead he was distracted, betrayed by penis that he looked down to find substantially erect. He looked at Clara to see her eyeing it too. Jeff picked her up by the sides, she was much lighter than she used to be. He brought her over to the bed, still holding her in the air.
"Hey! put me down at least!", she angrily motioned with all her twitchy little legs. Jeff calmly lowered her on the floor, placing her face down-ish as he supposed was appropriate for the way her legs worked. He felt about 20 little claw-like legs scurry up his body. She didn't even glance at him before going down on him, working his cock with a gentle but desperately horny blow-job.
Clara's legs clutched his sides, and pulse rhythmically and she moaned herself. Her mouth was still her replacement sex organs from earlier, and she was clearly in organism. Her bottom two legs curled up into her vagina out of ecstasy, but without any added benefit. Jeff came quickly, and the two of them collapsed aside each other on the bed. He passed out unintentionally, only to awake hours later.
