It didn't long at all for the faculty to get word of the situation and call Jen down to the nurse's office over the PA system. Rachel went with her and helped push her ass through all of the doors.
It was a good thing that Jen's ass was like a cat. It looked huge, but internally it was actually tiny when considering bone placement. Nearly 75% of her ass was just a special kind of fat called b-fat. B-fat, was incredibly bouncy, and had the odd capability of being able to compress to an extreme amount. This is why she could squeeze through tight door frames even though her ass was way larger than it. It didnt take them too long to traverse the school and get into the nurse's office.
When they did enter, the Nurse had Jen swallow a pill. "This pill helps to suppress bouncerbabble and the giggling fits. But it only is temporary. I suggest you purchase them in bulk as each pill only lasts for roughly an hour. At least they work instantly." Informed the nurse.
Jen swallowed the pill and the effect was immediate. Her loopy expression went away and she returned a bit back to her normal personality, but only just a bit. She still was overly happy. "There, now you should be at least able to hold a conversation with us and not have us struggling to understand you" said the Nurse.
"Oh wow, my head feels so much clearer now. I can think a lot better too." Said Jen amazed at the difference. "That's what the pill does afterall. Now, let's begin. Rachel, I assume you are staying here with us, or will you be heading back to class?"
"I will stay if I can."
"As you likely should. Can I take it that you wish to be her at-school assistant then?"
"Um, sure I guess. What does that mean for me?" Asked Rachel.
"I will get to that later, but first. Are you feeling ok Jen, does anything hurt, or feel wrong?"
"No I feel great! Like really, really great!" Happily answer Jen. She was fidgeting rather excitedly too.
"That's good to hear. I am sure you also are aware that you are not normal, yes? You are a rarer case where your entire legs have been absorbed. Of course we are prepared as a school to accommodate you, but please remember that stairs are now your enemy. You cannot and should not ever, ever attempt to use them. You will almost certainly fall and could seriously harm or possibly even kill yourself if you fell poorly, or onto something. Your ass is made of a bouncier fat, but it isn't going to cushion your internal organs from a fall from a great height. Even a 6 foot fall can be lethal. So promise me never to use the stairs if there are more than 3 of them or without at least a few people to help you if you absolutely must use them. The last thing any of us needs is the death of a student/friend."
"Yeah! I totally understand. No stairs!"
The nurse nodded and then stood up from her chair. "Alright, let's get you examined. Rachel, since you are here, I will have you help us. You may need to do this for her too, so learn well." Rachel also stood up and followed the nurse, Jen was left waiting there because she couldn't fit through the door.
A few minutes later, the two returned with a tablet and a marker, as well as a pair of gloves each. Jen was asked to try and bend forward while Rachel helped lower her down until she was "laying on her stomach". She was not really, and more like, being solely held up by her huge boobs. But the concept was the same. Once she was down, Rachel and the Nurse went to her ass and careful seperated her cheeks apart. The it took a bit to open up the Sam, but when they did, they were met with what became of Jen's asshole. Basically it expanded to around 5 inches in diameter and became completely incapable of being controlled by Jen. The nurse moved quickly and took a few measurements then smooshed her asscheeks back together. "You have to move quickly when examining her like this. Her body now is wierd to begin waste excrement whenever her asscheeks are split apart like that. She has no control over it, nor can she hold it in either. But the moment she is sealed back up, all of that halts." Explaines the nurse.
After jotting down a few notes, she then takes the marker and begins drawing right on Jen's ass where ever she felt a lump or a harder spot. "Now I am making her new skeletal structure to get an idea of how and where her body placed her bones and such. After she finished, it seemed that for the lowest foot and a half, Jen's ass was now pure b-fat. And she had about a foot to every side around her too.
When it came to her bone layout, it was as if she was permanently in a half squat, and her legs were half as long. She hopes not because she shifts her weight, like Jen thought she did, but by extending her legs and bending them rapidly. She is essentially jumping, but just inside of her ass. The compression of the b-fat beneath her is what lifts her up when it springs back from being compressed, pushing her up and off of the ground.
Interestingly, the nurse also explained that it is extremely common for bouncerbutts to have excessively large breasts. This is because of a new purpose they aquire besides nursing babys. Their new weight helps allow the bouncerbutt to easily move forward, as ththe larger boobs move their center of gravity forwards quite a bit. Jen and Rachel also learned that Jen cannot actually bounce backwards because of this as well. Of course Jen tried it, but at best only managed to move 3 inches forwards at the smallest. Even when she was fully leaning backwards.
Several tests, lectures, and 3 more pills later was when Jen and Rachel were allowed to leave. Jen had been given a slip of paper with what her required waste pipe and door frame dimensions are, as well as a detailed info packet and a bottle of the pills to keep. She was told to only take them when she needs them. And not just because she isn't on them at the moment. It was about time for lunch so Jen and Rachel headed off to the cafeteria.
