Brain Transfer (tentative title); by The Bizarre One
- Set ten years after the previous story. Liza, who was about ten during those events, is now twenty.
- Tags: Masturbation. (And that's pretty much it. Seriously, there isn't actually any real guro in this part - it's more a set-up for what's to come, and references to events that have happened during the ten-year gap, including a couple of people who got harvested.)

It was another day in Twilight's castle, and the alicorn woman was walking the halls. "Liza?"

No answer came, and Twilight frowned. "Where could that girl be?" Continuing on her way, she finally heard a faint humming sound, along with moans of delight, coming from the Brain Room. At that, she smiled. "Of course. I should have known."

Peering through the slightly open door, she was treated to the sight of Liza Doolots, her apprentice of almost ten years now, wonderfully naked and splayed out in a beanbag chair as she pumped an object in and out of her cute little cunt. At one time, it had been the horn of the unicorn woman Starlight Glimmer, until Twilight herself had cut it from the other woman's head and, after charging it with magic, repurposed it as a vibrator, just as her friend Rarity had done with her own little sister Sweetie Belle's horn all those years ago.

Twilight still remembered, rather fondly, how she had presented the converted horn to Liza on her eighteenth birthday as a coming-of-age gift... and how Liza had asked her to be the first to use it, explaining exactly what she wanted. And so, at her student's request, Twilight had attached the horn to a belt and used it to personally take the girl's virginity. That night, a little over two years ago now, had been the first time she had ever made love to her apprentice... but definitely not the last. Even after finding a marefriend (who had actually been one of her childhood friends) of her own about a year later, Liza still occasionally shared her teacher's bed from time to time. (Luckily for all of them, Dinky Hooves didn't mind sharing Liza with Twilight, and had even joined them a few times.)

Now though, Liza was thrusting the horn in and out of her cunt all on her own, and if her soft little cries, the motions of her wings and the flashing green and blue lights on the jar wired to her neck were anything to go by, she was on the verge of climax. Still watching, Twilight's smile widened as a final joyous cry erupted from Liza's throat before she slumped, panting as she tried to catch her breath. Finally, when she had recovered, she looked up to see her teacher, who had entered the room and looked amused. "You two enjoying yourselves?"

Liza shot to her feet, blushing, while the jar's lights blinked. "Yes," its vocalizer said.

"Good. Now, clean up here and then take a shower, would you?" Twilight told her. "We've got a brain swap job today, and they'll be here in an hour, so I need you to be ready."

"Miss Derpy?"

"Has anypony else ordered one in the last six months?"

"Point." Liza smirked. "Just like this one." She held up the still wet horn.

"Very funny," Twlight told her.

"I try." Setting the horn down, Liza began disconnecting the wires from her neck. "See you later, Starlight."

"See you later, Liza," the jar told her as she set it back on its shelf.

Picking up the horn again, Liza passed her teacher as she headed for the door. "I'll be ready when you are, Miss Twilight."

"You know, after everything we've been through together, you really don't have to call me that," Twilight told her. "Just Twilight will do."

"Force of habit." Liza shrugged. "Besides, I think you like it when I call you that. Especially in the bedroom."

Twilight laughed and swatted her energetic apprentice's rear. "Get in the shower, you."

With a laugh of her own, Liza disappeared into the hall, leaving Twilight to look around the Brain Room, reflecting on the past once more. For almost ten years now, she had been storing disembodied brains in this room. The day she'd officially designated it for this purpose, there had only been two. Now, there were many, many more.

On the first and uppermost shelf, six jars housed the brains of the first four Cutie Mark Crusaders and the duo of Diamond Tiara and Silver Spoon, their former rivals, all of their lights softly blinking green and blue: a good sign. In the first days after they were harvested, the two bullies had been utterly horrified by the experience, and the lights on their jars had glowed red as they screamed. That had changed when, to their astonishment, the three girls they used to torment had reached out to them and helped them adjust to their new lives as disembodied brains. Now, the five (and Babs Seed, the fourth Crusader who had, after learning of the sacrifices her friends had made, promptly offered up her own body so she could stay with them) were all the best of friends. Though the vocalizers that had been installed in their jars were silent, all of them were linked to instruments that measured brain activity. Judging by the results it was displaying, Twilight had little doubt that the six were happily chatting away via the mind-to-mind connection they'd all developed.

Below them sat several more shelves, occupied by the brains of other young ponies who had, like the Crusaders, willingly sacrificed their bodies so their parts could be used for other things, and had chosen to remain bodiless afterward. As with the first six jars, their vocalizers were all silent and the status lights glowed green and blue, signifying that they were calm and at peace with their condition. But based on the readouts she could see, they too were most likely all involved in the conversation that the Crusaders were holding.

The third set of shelves to be installed housed the brains of ponies who had fallen ill or been badly injured, and had chosen to be harvested, allowing them to live on in a reduced state until new bodies could be grown for them, a process that Twilight and Liza had perfected together. As a result, this section had the highest turnover rate, and currently sat empty. Twilight was torn between smiling and frowning at that: smiling because having nobody there was generally a good thing, frowning because it should have had at least one occupant after the accident that had taken their ability to walk almost six months ago. But despite the injuries she'd suffered, Derpy Hooves (a friend of Twilight's and the mother of Liza's lover Dinky) had chosen to remain in her original body after the accident, wanting to be transferred directly into its replacement, an event that would occur later that day.

The fourth set of shelves held the brains of grown ponies who had chosen to give up their bodies for a life free of the distractions of the flesh, allowing them to ponder the universe in solitude. Naturally, these were few and far between, but Twilight had been so intrigued by the idea, she had given them their own section. The readouts were at normal levels for these brains.

Turning, Twilight contemplated the final shelves. Actually the second area that she had set up, this section of the room housed the brains of certain criminals, such as Starlight Glimmer, Lightning Dust, Suri Polomare and the Siren duo of Adagio Dazzle and Aria Blaze, all of whom had been stripped of their bodies for their crimes. Due to Equestria's incredibly low crime rate, it had the lowest population; after nearly ten years, there were only twenty brains, and most of them had come in that first year, after which point the worst of Equestria's population got the hint and changed their ways.

As with the other shelves, the readouts were normal, which was very good. These were the brains that required the most care, especially when they had first here: none of the residents had given up their bodies willingly, and as with Diamond Tiara and Silver Spoon, many of them had been horrified by the loss and suffered from panic attacks that could have eventually caused them to go insane and die. While she and Liza had personally cut into these individuals to remove their brains, neither wanted the ponies they'd operated on to die, and had taken great steps to prevent this from happening. They had spent hours talking to the brains, hoping to calm them and get them used to their new condition; they'd also searched through hundreds of books for spells that, when adapted, allowed the disembodied brains to experience limited physical sensations once more. Between the spells and their conversations, they had kept the brains sane and alive.

Later on, Liza had begun experimenting, hoping to take what she'd learned about these spells even further. Finally, she had developed a method that would allow one individual to feel the very same physical sensations as another. (She'd also made sure the connection would only go one way, to prevent potentially hostile beings from using the connection against the pony they were connected to.) When she'd finally shown it off to Twilight, she'd wired her nervous system to a jar with the brain of a girl who had volunteered for harvesting, and had begun masturbating. To her great joy, it worked perfectly: the brain began experiencing the same type of pleasure as she did, including her climax... and that moment of joyful delirium had resulted in something wonderful.

As Twilight later explained it, at some point when she was still living with her parents, Liza had earned her flower Cutie Mark for her boundless energy and the potential it presented (though she was quite sure it symbolized her physical energy in general, not just sexual energy, since that was something she'd never even thought about at the time). Now, her creativity had allowed another to experience that same energy as it was released. Coupled with the Cosmic Spectrum she'd made the connectors out of (because of its ability to amplify energy and emotions), this seemingly impossible feat involving her special talent had been enough to trigger her transformation into an alicorn-girl, something that had made Twilight very happy, since it meant her apprentice was now as immortal as she was.

Having succeeded in her proof-of-concept, Liza had, with Twilight's approval, added the system to all of the other jars. Now, with the aid of willing volunteers, the brains within were given the chance to experience physical sensations, including the pleasures of the flesh, at least once or twice a week. (Liza was especially fond of the "masturbation method", as was Starlight after the first time she'd experienced it.)

Some time after that event, the two had developed a way to take Liza's system to the next level: allowing the confined brains to experience true movement under their own control. Modifying the system so its connections went both ways, they could link the preservation jars to small, golem-like bodies. By melding their thoughts with these bodies, the brains could remotely control them, experiencing each movement as if they were truly walking again. This gave the brains more freedom, even if their range was somewhat limited. (After all, most of the brains who used it were still criminals. Twilight, despite wanting to keep them alive and sane, had no desire to let them take advantage of her generosity to cause harm to others.)

Shaking herself out of her recollections, Twilight let her eyes sweep over the room one last time before leaving. Dinky and her mother would arrive soon, and she had to make sure the laboratory where they would perform the transfer was all ready.

***
Upcoming events: Twilight and Liza greet Derpy (whose spinal cord was severed in the accident six months ago) and Dinky, we see the brain-transfer surgery, Derpy's old body gets harvested, and it's mentioned that Sunset Shimmer and Sonata Dusk (the last of the three Sirens) are a couple (hence why Sonata's not in the Brain Room with the other two).

Any thoughts? (And no, I still haven't forgotten about Starlight's eyes, bones and ovaries - they'll be included in something taking place not long after my previous entry.)
