Equations

"Say, mind if I do all your homework for you? My brain is aching for equations to complete." Liz asked them innocently which looked comical at her current appearance. Wordlessly the girls handed her all of their books as Liz quickly snatched them and started greedily jotting down the equations and answers.

She seems's almost addicted to it as her hands were moving so fast them were a blur and she had a look of hunger in her eyes, like how one would stare at a delicious buffet before proceeding to gobble down everything. It was both amazing and slightly terrifying as she was quickly finishing a couple of books already in seconds from both of them. In less then 20 seconds she has finished the entirety of their syllabus too. Her pencil has been considerably shortened but she managed to get another one.

"There! Not only have I finished your homework and entire syllabus, but I have also written down some notes and key points that would help streamline and simplify the equations for you to help in the future. Don't worry, I've written it in a way you would understand!" They looked through their books to see if it's true and turns out it was. Liz has written down bullet points, keynotes, equations and several other things in a perfect, calculated, beautiful, articulate and understandable handwriting that has made it several time easier for them to understand and absorb better then their teacher ever could!

"Oh thank you so much Liz!" They both exclaimed loudly as they jump forward to hug her in appreciation, which was kind of awkward considering her size, even while sitting down, they just ended up sinking into the sides of her massive, milky breasts. But they didn't care as Liz brought up her hands to gently and lovingly rub their backs and heads as sighed into her dark tanned flesh, sinking further into their comfort.

"Your welcome girls. It's no big deal for me really. But my brain still feels unsatisfied and craves more so how about this. You go into my brother's room and grab all of his texts books and bring in an extra A4 book just in case and some pens too." Feeling saddened to leave her warm and protective embrace but eager to help her further, they rushed towards Josh's room and grabbed all the of his high school books they could find. Algebra, geometry, chemistry, biology etc, all subjects which were beyond the levels of what the girls study and the a thick, hard cover, A4 book with 200 pages and some pens Liz asked for and ran back to her side.

Liz stared at the books with an intense hunger in her eyes as they arrived in her room, a vein pulsing on her head as it waited eagerly to devour new knowledge. The second the girls set the items down on the floor in front of her, she immediately leapt at it, grabbing a random book and pen and quickly jotting down notes at incredible speeds. She was breezing through the high school books, a vein pulsing angrily on her large head.

The girls had previously peeked at the books before and noticed instantly that those subjects were far beyond their current grade. To see this 18 year old turned super genius who was also a grade below the going through it like it was no big deal was strangely arousing in a way. Her mental prowess able to completely dominate subjects that would have been impossible for any body to accomplish, crushing them with her pure, intelligent might. She was able to become this smart only from what little contents were remaining in her stomach. Imagine a full belly, completely dedicated to her head. Just how much bigger would it become? How much more knowledge could she gain when she's already far beyond the vast majority of the human race. All these thoughts came crashing down on the girls as they began to masturbate intensely at the image. A super intelligent Liz, able to guide them far into the future and beyond and completely revolutionize the field of science, math, astrology and other subjects. It would be incredibly sexy for a person like her to lead them while completely and shamelessly flaunting her superior body and self in every way she could.

Meanwhile Liz is greedily writing down notes on the books in a beautiful but understandable cursive handwriting that would make a professional jealous and putting down easily digestible points that have streamlined and simplified the syllabus that would greatly help Josh ace the exams in the future. A vein was gently pulsing on her head as the subjects provided adequate challenge to stimulate the brain just enough to satisfy it's cravings. She was going through pens a lot faster because of the sheer quantity of notes the books provided. Finally, in just under a minute, she has finished the entire high school syllabus. She placed the books on a neat little stack on her table while she dumped all the empty pens in the trash.

"That was all... adequate but there were a couple of problems in it." She said. The girls instantly shot up and looked at her. What sort of thing could ever be a problem for her?! "Well for starters, the school syllabus just feels so, for a lack of better words, bad in quality. Like seriously, they provide convoluted explanations for the subjects, the questions are overly dumb, it feels like it's treating the students like a bunch of idiots and a slew of other problems. No wonder my brother is having problems with collage, they are simply just bad in every department. If it weren't for just how terrible the books are I would I have finished it in less then half the time!" Liz is now breathing hard as she just finished her long rant.

Taking a gulp of air, she sighed. "But that doesn't matter any more because I rewritten the note in a way that would greatly help Josh in the future. God I just can't believe how poorly these books have been put together and I dread to think how incompetent the school he goes to is." She said as she massaged her massive head. "Despite the books stimulating my brain, I still feel like there's a bit more that I could do, which is why I asked you to bring that extra book." She said as she picked up the hard cover A4 book and a pen. "I just going to write down some equations for a 'special project' in the future. Not that you would understand it anyway but it will be a big surprise later on. In the mean time, why don't you rub my head while I do it, that wold sure get the blood pumping." Wordlessly agreeing, the girls got up and approached her as Liz laid down and lowered her ponderous head for them to reach as she opened the book and started writing down seemingly random equations.

The girls were hesitant at first as Liz's massive cranium dominated their view. Slowly, they raised a hand towards the large dome and placed it. It was simply alien but in a good way, it was unnaturally warm that fought off the cold, the thick, long brown hair felt like silk in their hands, the flesh, just soft enough to squeeze in a comfortable way and the skull underneath it, hard beyond comprehension thanks to Liz's absorption of metal into her skeletal frame.

They weren't just rubbing her head with their hands, they were now hugging and cuddling it to the best of their abilities from a standing position as it felt like it's own separate entity as they could feel the sheer power of it's intelligence pulsing through the body in a comforting way. Liz meanwhile focused all of her attention on the equations she was writing, going at a MUCH slower pace then when she did the homework of everyone but still faster then the average human being. Being curious one of the girls decided to take a peek at what she was writing but immediately turned away and buried her head in Liz's forest like hair as the equations gave her a splitting headache.

To say they were complex is a MASSIVE understatement as they made the equations in Josh's book look like child's play. What ever she was writing for this 'special project' of her's, they were literally unable to comprehend it. As the writing went on several, thick veins were now pulsing angrily on her head and gave off much more heat as whatever she was writing, was doing more then just 'stimulating' her brain as it was now finally being used to it's FULL capabilities as they girls hugged their entire bodies around it, relishing in it's comforting warmth and pulsating power as they rubbed, kissed, massaged and did whatever they could to bring pleasure to this super brain.

Finally, after what felt like hours but were actually minutes, Liz was done with the book as she finished 50 pages of impossibly complex equations that would serve in this project of her's. "Whew, now THAT'S what I call a workout out for the brain. Felt like one hell of a pleasure trip of knowledge. Despite all that though the equations are incomplete but my brain got what it wanted, don't you think so girls. Girls?" It was now that she noticed that they were hanging onto her massive head that was still pulsating and giving off heat as the girls tried desperately to pleasure which Liz now noticed actually felt pretty good.

"Awww aren't you two being absolute darlings, but I'm afraid I'm going to have to end it here girls, shows overs." She said as she gently plucked them off her head. They were now fighting desperately to get back on her head as they writhing, struggling and punching her arms which was useless as she barely felt a thing and still had an iron grip on them.

"Woah girls chill out I'm trying to help you! Tell you what, I have a plan that wold satisfy us both." They both stopped their struggling and were now listening, if only for a moment.
