Mary fell to her knees in exhaustion. Planting her hands on the floor so she wouldn't fall flat on her face, she quickly saw that the teleport had succeeded to fail, and she was now part woman, part wetsuit. The seam at her neck was gone, Mary quickly discovered as she plucked at the base of her neck with her gloved fingers. Reaching behind her back, she could still feel the line of her zipper that ran over her spine, but despite its roughness, the sensations she received were not much different than normal skin on skin contact.
After recovering, Mary got back to the mirror, and examined the way she now looked. Below her neck, her whole body was now black and grey in color. Stretching her arms out, and raising them up, she was met with absolutely zero resistance in moving them, nor any sensation of chafing like she used to feel when she moved around too much in her wetsuit. It was now part of her after all. The soles of her feet no longer felt the coolness of the tiled floor of her dad's laboratory. Their rubber material provided also an anti-slip surface to walk around on, making her life much easier in general. The gloves were made of similar material, at least in the palms of her hand, so her grip on smooth surfaces improved unconditionally.
Her knees didn't hurt because of Mary falling. Instead, the her skin had actually gotten somewhat thicker, thanks to the multiple layering the neoprene wetsuit was made of. The thicker skin gave her more protection in a general sense.
Mary's excitement rose, as she figured out that her new cloth-body actually provided her with some unique abilities people normally didn't have. She looked down at her chest, only to see that her wetsuit didn't hide all of her changes perfectly. The shape of her boobs and but was still evident underneath the darker 'skin'. Seeing herself in the mirror right in front of her, she wasn't able to distinguish the presence of her nipples, their color changed so they'd blend effortlessly into the rest of her black wetsuit. When she looked down though, she saw the two tiny teats harden before her eyes, her blackened nipples turning erect and tingling in arousal.
That's when the girl decided to look down at how she'd changed between her legs. Spreading them apart, she brought her fingers to her groin area, to locate what she knew would be her erect clit and her eagerly waiting pussy.
Running her fingers over her pelvis, she quickly found her clit. Mary shivered in pleasure as she flicked her bean a time or two, before trying to see exactly where her pussy lips started, and where her opening lay.
Mary discovered it had something to do with the seam of her wetsuit. On her back, where the zipper ended when fully opened, a seam ran further down her back, over her buttcrack, and down to her private area. This very same seam now functioned as the outer lips, the labia majora, of her perfectly ebony pussy. She spread her lips, to discover the fleshy insides of her cunt, her vaginal walls, of the same grey color of the suit that now also ran over her arms and sides. Letting go of your hot and swelling pussy lips, you look just like a perfectly normal girl wearing a regular wetsuit again, ready to go out to the lake for a nice and probably wet surfing session.
Talking about getting wet, it was impossible to ignore the tingly sensations she now felt in her groin and nipples. By stimulating her nipples, Mary could feel herself getting increasingly moist down below. And yet, her suit betrayed no evidence of her arousal, as Mary quickly discovered that every drop of the juices that leaked out of her snatch, quickly got absorbed by the fabric of her new skin right between her thighs. And as her arousal grew, so did the warmth between her legs, as the dampness in her crotch got trapped inside the many layers her skin now consisted of. The sensation made it ever more pleasant and stimulating.
Mary hurried out of the basement, and ran back up the stairs, into her room. If this was how her new cloth-body worked, she could pleasure herself for hours on end, without the slightest trace of musky juices being left behind on the surface she got herself off on.
The teenager landed on her bed, her gloved fingers quickly reaching into her snatch, jilling herself off, as the sound of her moans were muffled by her cushions. She quickly reached her climax, ejaculating underneath the covers of her bed, her juices getting caught by the lips of her pussy and the absorbant skin of her thighs, as she felt the areas on which it landed warm pleasantly in response.
Returning to her senses as she lay in bed, Mary began contemplating what else she could do in her body's new wetsuited glory.
