As deep as you can go

"You really don't mind if I take up a long-term residence inside you?" you asked, glancing again down at Jan's body. It wasn't yet fair to call this form your 'self', even if you occupied it and could consume its senses and move its limbs. This form was still Jan's, through and through, even with any changes you might make to it.

I'm ready for that, came the reply from within your mind. Please, stay with me, be me! You can do anything, I don't care, just don't go. After feeling what you can do to me, knowing you can do more, that's all I want now. For you to be in charge of my being. For you to somehow go farther than you already have and become me!

That was a tall request. It's one thing to just move a body around, or pretend to be another person. But it really sounded like Jan was surrendering everything about herself to you, in the hope that by having you in charge of her entire existence, she will experience a closeness unlike anything she could have imagined with another person. To her, this was nirvana, a heavenly possibility made real only by the supernatural abilities you'd obtained.

And to do that... there was only one way you could think of.

"Jan, listen carefully." You sat Jan down on the bed, as you beckoned a towel forth to wrap around your head to dry her hair out. "What you're saying I should do, if I'm to do that, it's going to be through your brain. Right now, I'm saturated pretty heavily into your muscles and stuff, I can feel that, but other than brief poking and prodding, I'd left your gray matter alone. Now, I could push my energy deep into your mind, but then that means I'm in charge of your every thought and decision. They won't be your thoughts any longer, they'll be mine. You'll exist, but as an extension of me. Do you understand?"

You felt your body shiver, almost spasming into orgasm then and there! I want to be an extension of you.

Well then. Who were you to say no to such a request? You can mold Jan's body and mind to your liking, you still can do whatever you want with your girlfriend, you've got otherworldly powers... it makes sense to burrow deep into the mind and solidify this reality. You laid down on the bed, closing Jan's eyes, and you got to work.

Your energy slowly pulled out of Jan's limbs, not needing to push and pull her muscles once your next step was done. Your ghostly essence flowed into Jan's mind, permeating the space between the neurons, linking with the synapses, filling out her mind. To Jan, it was like a sudden, elongated dream. Every brain cell you touched seemed to fire off a random thought, none of it being connected to anything but it washed over the conscious mind like a bizarre hallucination. You seemed to claim Jan's mind cell by cell this way, where once you knew what memory was stored in a cell, you locked onto it. The process sounded tedious, but in fact it went rather quickly, you just seemed to fly right through these blips of memories as if time was meaningless to you. Jan could feel herself being lost--no, not lost, you decided. Assimilated. She wasn't going anywhere, she would remain fully intact, but you were the keeper of even the smallest inkling of ideas within her. You were at the helm of Jan's mind and therefore her body, with the ability to push her to do anything you like as your mind was essentially combining with hers.

Jan's body writhed and shook, squealed and groaned, throughout the entire process. Her motor functions were becoming your motor functions. Your intent was to be funneled into her mind, to drive it forward. Jan would move how you told her to move, say what you wanted her to say, sense what you wanted her to sense. The beauty of your method was the level of control--you could focus and take charge of the finest detail of her thoughts and therefore actions, or you could release your grip a little and nudge her in the right direction to let her take things the rest of the way. In this sense, an 'authentic' Jan was always right at your fingertips, although you thought it would be unlikely that she would ever truly act like she had before so long as you were in charge. It would be useful to tap into her understanding of herself and her life, or let her braid her hair once ready, but you planned to keep your calm, confident demeanor intact and make Jan behave in a way that matched her new alluring look in addition to that beautiful face.

One final push into her mind... and your very innermost essence enveloped the parts of Jan's mind that made up her consciousness. Her conscious mind became tethered to yours, quite literally with how your ghostly essence wrapped around the neurons and synapses! With your absorption into her consciousness, you were Jan, through and through. You assumed her assimilated identity then and there, as you took a deep breath like you were inhaling for the first time.

You sat up, looking down at yourself. It felt the same... but it felt different. Like this had always been you. This body was so incredibly familiar, even though you knew better. You were just able to feel that familiarity from deep within your mind.

With a smile, you tugged the towel away from your hair, and twirled your finger in the air. Your hair automatically started to braid itself, a combination of your ghostly powers and your knowledge of hair that you'd braided thousands of times before. It felt so natural, like you'd always done this... you smiled even wider. All of these thoughts and memories from Jan were really easy for you to assume as your own! You were going to need to be careful so as to not be lost within the mind of your host, and forget who you really were. You still had things that weren't related to Jan's life, after all, which you needed to take care of. In particular, your fiancée...

Your fiancée! You didn't know if she'd awakened yet or anything! You bolted upright, hurtling forward toward the door, not even bothering to try and walk or run. Your feet glided along the ground, toes barely an inch or two off the carpet as you exited one door to enter another across the way, to check in on Jane. You couldn't wait to show her the new you that you'd created, and to put this body to good use! You just weren't exactly sure just which Jane you were going to encounter when you finally found her. You desperately wanted an audience for these supernatural abilities, and who better to use such powers on than your girlfriend?
