I should stop, but it won't come out!

It took some effort, but Kasumi finally **** herself to reach back and grab the dildo. She pulled the first bit out, but when she grabbed the next handful it slipped through her fingers and sucked back in. Each time it slammed back into her it shook her body with more pleasure. She tried for several minutes, with the same result, before finally giving up and deciding to try pulling it out through her mouth.

The and coming out her mouth was just as slippery, but she could get a better grip on it. She got a little excited as it began coming out before the base slapped against her hole. The hilting hit her with another orgasm, but she was determined to hold out. It didn't seem too big at first, so she decided to try and just pull it through. Kasumi felt it stretch her ass open as she tugged from the opposite end, until she felt it pop through.

Kasumi grunted through her filled throat as another orgasm flushed through her, but something felt odd, and she realized the dildo was not only still gaping her ass, but she was now plugged tight, with an even larger base now slapped against her ass. She could feel it, and knew that she wouldn't be able to pull that one through. She was also extremely frustrated as she knew there was no plug at the end when she originally inspected the dildo, but there were a lot of things different about this dildo than when she opened the package.

She spent another minute in futility trying to expel the plug from her ass, but it felt like it just grew every time she tried, and the feeling of pressure and increased pleasure made her weak again.

As she began giving up she noticed rubber sprout from the base and extend outward. Looking down in the mirror she could see the dildo snaking up between her thighs, and begin rubbing against her swollen vagina. The smooth feeling stopped her in her tracks, as it rubbed perfectly against her clit. It almost bright her completely to orgasm before momentarily stopping, causing Kasumi to let out a muffled cry, before shoving itself deep into her vagina and bringing her to climax.

Kasumi squirmed, her muscles tensing once more, as the intruder in her vagina didn't stop its movement. And with each flinch of muscle the dildo inside her body rubbed and flushed even more pleasure through her.

It was so overwhelming she almost didn't notice the initial prick of pain as a thin end pieced through her cervix and into her womb. The slow growth definitely caught her attention though, and her hands rushed down to try and pull it out. As of the intruder knew what was coming she felt the rubber flatten over the top of her vagina, completely encasing her snatch and leaving a slick surface of latex running from just above her clit all the way back past her abused ass hole. She rubbed at it to try and get a finger hold, but it just seemed to stimulate her clit even more and shaking her with yet another orgasm.

Kasumi felt helplessly as the rubber stretched her vagina to the breaking point, and dilated her cervix as it filled her womb. She could see the bulge begin as the rubber began growing and inflating deep within her. She already looked extremely pregnant with the tendriled mass of rubber dildo still squirming through her intestines, so the bulge from her womb was even more pronounced than it normally would have been, and she grabbed a hold of her belly as it stretched further. She was worried about the damage it would do, but looking at herself through the mirror it was almost like her body was made of the same endlessly stretchable rubber at this point. There were no signs of stretch marks, or tearing of the skin, and it seemed to be able to grow endlessly as it needed.

Between climax after climax, forcing her muscles to spasm, she finally was able to open her eyes again and inspect herself in the mirror. She remember seeing an image, years ago, of a woman with pregnant with quintuplets, and she would be lying if she didn't admit she appeared 9 months along with just as many.

Kasumi almost caught her breath at last, as it seemed the growth had finally stopped, but she let out a muffled moan of pleasure once more as the vibrations started. From her clit, all the way into her overstuffed womb the latex began vibrating violently.

Groans of pleasure excited through her lungs as she bit down on the rubber in her mouth, holding on as every ounce of energy was spent holding get body together through this next series of orgasms.

Tears steamed down her face, not from pain, but as her mind broke and finally accepted her fate as a doujin fuck toy for this living mass of rubber.
