The first time it happened, Maria didn't recognize it. Only afterward, once it became obvious, did she understand what she had felt. As she rode her boyfriend Fernando, bucking and moaning in orgasm, there was suddenly a loose and sliding sensation, centered down on her vagina. Maria was rather distracted by her pleasure, however, and the sensation was quickly gone, fading as she settled down again, leaning forward to lay her ample breasts on Fernando's lightly hairy chest and kiss him on the mouth. She pulled herself off him, enjoying the feeling of his softening cock pulling away from her sticky cunt, and they went about their postcoital snuggling and petting.
The second time, a few days later when they slept in for a lazy Sunday and Maria climbed on top of Fernando once again into her favorite position, she felt a little odd, like they weren't quite settled right. But she started working herself against him, pushing his lovely hard cock in and out of her lower lips, slathering him up with her juices as she took him gradually into her, and any concern faded into insignificance behind his hands holding her tightly to him and her rocking climbing joy in being filled so tightly and so deeply. Once again, right at the end, after she started to shake and twitch around him, she felt that unusual sliding feeling. Strange, but he was hard and tasty and he hadn't had his orgasm yet, so when she had come down off of her plateau, Maria settled herself sideways and sucked his cock while she dripped slowly on her bed.
It was only later, when she was dressing for going out to lunch, that she first actually noticed something odd. Above her panties stuck a little tuft of pubic hair. Now, Maria had never been one for shaving. She saw no point, and figured that any man who didn't like her with what God gave her was not worth having. But her hair was not extensive either. She knew her body, and she knew that her pubic hair was usually kept well-contained within her underpants. That's just how it grew. Or how it had grown, previously. But now, there was definitely a patch of curly brown hair sticking up, nearly a whole centimeter above the top of the fabric there. She wondered at it, but figured that maybe she was misremembering somehow, or maybe her panties were riding low or she'd put on weight or something. And a bit of stray pubic hair was nothing to really worry about. After all, she wasn't about to shave it anyway, right?
But they had one more round of sex before Fernando had to leave for the night, to go back to his apartment and prepare for his work week, and that was what pushed things over the edge to where Maria could no longer deny that something strange was happening. Nude and blissed out, one more round of cowgirl pleasure capping off her weekend nicely, Maria did not realize it then. She smiled a lazy happy smile as she listened to her boyfriend dress, kissed him a lascivious and groping goodbye, then slowly drifted off after he had let himself out.
She woke early, as she usually did to have time for a workout before she showered and went to work. She was still deliciously sticky and nude and could smell the sex on her from her evening fuck with Fernando. Maria smiled to herself as she pulled on her old panties, getting just dressed enough to exercise, and then stopped cold, feeling like a bucket of ice water had just been thrown across her back.
Sticking up above her panties now was a portion of her labia. The curly pubes around it were higher still, nearly two full centimeters above the top of the panties, and under them were her clit and the top of her vaginal lips. She touched herself, and yes, that was definitely her vagina, and it was definitely out of place. Now she was freaking out. How could this have possibly happened? Was she OK? Did she need to go to a doctor? It didn't hurt or even feel bad, it just was not where it was supposed to be.
She pulled the panties off again and got a hand mirror out, lying back down on the bed and looking at her crotch. Her pubic hair, the shape of her mons, everything looked basically normal to her except that her vagina was in the wrong place. Too high up, by several centimeters, Maria guessed, though it wasn't like she had ever tried to remember exactly where her vagina was before. She'd never paid much attention to her taint either, not being into anal, but now she thought that her taint looked much longer than before, just sort of taking up the space that her vagina had moved out of.
