Yuki had the good idea to respond to a request for a candidate as part of an experiment, the idea was not suspicious given the number of participants and it would bring him money at the end, a small job rather interesting that she really needed these days

But while she was present on the scene, there was already a problem, something was wrong, the scientists were already nervous and above all, she was alone. They told him that the others were already in the tests but strangely it sounded like a lie or a hidden truth. Yuki still wanted to accept the offer and be done with it.

Here she is now being escorted down the dark hallway, turning one after the other and the cold and chilling atmosphere of the place reminded her of the worst horror movies she has ever watched. The scientists quickly broke the silence to show her the test room, just like the others, it had a single but empty and cramped chamber with only a strange metal frame, when they opened the frame, a vacbed was put it on.

The situation was strange for Yuki but not unknown, she even liked this kind of deviance, this feeling of embarrassment excited her while she was undressing, going through it was easy, everything was lubricated, she placed herself in a position that reminded her of some hot session and it was starting to weigh on her vagina, she was already afraid of getting wet in front of everyone. She didn't have time to finish thinking that the sound of the air and the suction could already be heard as the rubber tightened on her, her shapes gradually appeared on the vacbed and she was now sealed. inside and each of his meager gestures was useless and accompanied by humiliating rubber noise.

During the sessions, they began to study her, measure, analyze her body, and above all to touch her, Yuki was not really against it but did not know how long she could still hold back, the vacbed was strangely flexible and adapted too much to her body, their fingers passed through her vagina without coming into contact with anything, the rubber was still blocking as if the vacbed had also spread inside her, Yuki had no time to get confused when it came quickly inadvertently following multiple manipulations.

While she was humbled to have come to orgasm, no scientist was shocked at the action, one of those who had been left behind stood up and told the others that she was "ready".

She didn't even have time to ask why she was so that one of the scientists lowered a plug from the top of the frame towards her muzzle and made her bite the tip, another came out of a strange prickly ball from the frame towards her vagina. He told her it was the last experience, after that she would be free, everyone headed out as the metal frame descended on her, the balls slipped gently into her vagina, each one of them was bigger and bigger and their penetration gave her immense pleasure, she couldn't even fight it in this tight rubber frame, even her moaning was imperceptible and was blocked by the plug in her mouth as well as two nasal pipes which descended gently into She.

When the frame sealed, she felt her whole body lock even more accompanied by a noise of air, a second vacbed had just sealed the first on her, as well as her face. Completely prisoner of the vacbed, Yuki could now only count on the scientists to get out of it, she prayed that the experience was not too long, the balls located in her vagina gave her a very painful experience and also a lot of pleasure, it was so humiliating to be stuffed in total helplessness.

The poor will never know that on the top of the frame that had just sealed her was the name of her experience, While the frame was sealed and blocked, the locks were heard and the electronic frame of the wall indicated:

"Permascelled done - time remaining undefined"

Unfortunately for her, she will soon have only the sensations of pleasure from her vagina to feel that she is still alive, forever prisoner of her box, ready to lead her existence with the conviction that one day, her frame will reopen. maybe...
