Standing there, Erik had a hand to his chin in thought. He had delved into the mind of the Penelope, or Pen for short, and found an interesting desire. It became obvious to Erik that some of the fantasies these girls had were possible, others were not. The fact that they were often pure fantasy meant that some of the girls dreamt of scenarios Erik could never fulfill. Fran for instance wanted to have sex in space with a fictional character from one of her favorite books.
Sure, Erik could manipulate the mind of Fran and make her think she had done just that. But he had decided that he wanted all the girls to remember their encounters, and to believe they actually happened. That was a truly tricky part, as he found out with Marla. The girl had her sex scene in public, but knowing that it had happened would have embarrassed her to death. So Erik had to settle for making her think it was the best dream she ever had. In comparison Shelly was much easier, as she remembered everything. Everything but the fact that Erik had put some mental commands in her. That made it much more satisfying for him.
Pen looked like she was going to be a real tricky one. Looking into her deepest thoughts, Erik had found a rather unique fantasy. Having looked into the minds of lots of girls, he had come to see that the vast majority of them had little or no desire to be raped. Some liked the idea of being submissive, but despite what many guys would have liked almost none of them desired a true rape.
But Pen was the closest to that desire then any other girl he had delved into. Her darkest desire was to be taken, forcefully. If that's all it had been, Erik could have easily obliged. Hell he had already done that to her before, just wiped her memory of it. No, Pen had a much more fantastic scenario in her mind. The girl wanted to be taken by something that wasn't a man. Not a beast or anything, but something more primal, elemental. He had to look deep, but Erik found in her mind the vision of being fucked by an invisible force. It did not seem like a realistic fantasy. What she wanted was not so much the rape, but the impossible magical nature behind it.
And that is when it hit him, a solution. Erik continued to stand there watching Pen as she worked. They were in a storage room, where a variety of school supplies were stored. Pen had come in there to organize, part of her duty as a teachers aid. She did not recognize that Erik was standing there, because he had commanded her not to. Erik realized though that this command wouldn't work. While she couldn't see him, she also wouldn't realize Erik was there if he touched her either. It was part of the command he used often to let him interact without upsetting anyone, and it wouldn't work for her fantasy.
Now he couldn't make himself invisible, but Erik realized he didn't need true invisibility. Instead he dropped his current command in Pen's mind, and replaced it with a new one. It stated that she simply could not see, hear, or even smell him. That specifically left out her ability to still feel him, and recognize it as out of the ordinary. Pen paused for a moment as the new orders settled into her mind, then she went back to work.
Erik decided to test it, walking over to stand next to her. She of course did not hear his approach, or see him when he stood no less then a foot away. Even when Erik waved a hand in front of her face she did not react. Well that worked, now he just had to make sure that if he interacted with her should would still feel it. This he tested by simply blowing softly into her ear.
Shivering, Pen put a hand up to her ear and looked around, wondering where that breeze had come from. She stood there for a moment before forgetting it and going back to work.
"Perfect." Erik said aloud, sure that she could not hear him. Though he did alter her programming so that she wouldn't feel his breath anymore, for it might break the illusion. Now all he had to do was set the stage, and Pen had given him the perfect scenario with her own fantasies.
Pen was moving a stack of boxes when she found a book sitting underneath one. It apparently had been stuck to the bottom of the box, as it peeled a bit before it had fallen off. Looking at it Pen realized the book was old, ancient, and she wondered how long it had been there. She had no way of knowing this was all an illusion in her mind, even when she reached down to touch the book.
Flipping through the pages, Pen's heart skipped a beat. It was written in some strange, fantastical language whose text actually glowed in the light. She had always dreamed of finding some magical tome, and wonder filled her eyes at the possibility of her find. Of course that was just silly, magic wasn't real. That's what she told herself, until she got further into the book.
There she found bits of equally old paper between the pages. They were notes, written in English. Old English, but readable nonetheless. They were attempts to translate the text, and they indeed spoke of mystical powers held within the book. But none of them held the power of unlocking that magic. Indeed many of the notes said that they lacked the information needed to tap into that power.
Then she came to the last page, where along with a full page note, there was a very thin stone between the pages. It was beautiful, and Pen held it in her hand for a long moment before turning her attention to the translation. Growing excited, she read it aloud.
"Of powers manifested, Orty of Fyen is simplistic. It power stone contained, using F'gard. That who Attm Irel shall bring it forth, no Qool. The Fyen serves a purpose, powered by Jdyinalit. It brings great Lyktun to the Xedri, serving without being seen. Although the stone is consumed for Cnasm, Fyen retains a simple Orty. One needs merely Tgir the word."
At the bottom of the note in bold letters was apparently that single word. Staring at it, Penelope held up the stone in her free hand. Then, feeling an electricity on her lips, she said aloud "Rohonovin." The stone flashed with light, then disappeared, leaving Pen wondering if she did something wrong.
With a smile Erik went to work. He knelt down next to Pen and put a hand on her shoulder, letting her feel his presence. In response she almost jumped in shock. There was something touching her, something invisible. Suddenly she remembered the note, the passage about not being seen. This was the magic of the stone.
The invisible force put a hand beneath each of her arms, helping her to stand. Pen just moved with it in wonder, staring at the empty space. Her heart was fluttering as the magic lead her across the room, and stood her in front of a spare student's desk. Then, without warning it forced her down onto it. There she was held pinned by the wrists, unable to move.
"What, what's going on?" She pleaded, a quiver to her voice.
Erik stood over her, smiling as he stared at Pen's attempt to struggle. Rationally he was pausing to let her squirm, to let the tension build. But he also did it just to look her over lustfully.
Pen had a somewhat plain face, accented by her simple glasses. Her chest again was nothing to write home about, even her shoulders and arms were rather normal. What Erik stared at were her legs. Pen was one of the tallest girls in school, and that height came almost entirely from her legs. Although she did not stand too high over Erik side by side, her waist went up to his ribcage. To top it off those legs were shapely, well defined and curved perfectly. He had to touch them.
Erik released his hands from her wrists, but Pen was still held down. He had put a simple command into her mind, making her think that she was still being grasped there by the invisible force.
