The expertise-magic potion.

I glanced downward at my thin feminine frame and thought that a big burly warrior didn’t really fit that well. What did fit, however, was something more subtle and fluid; snake-like, some might say. But I also liked the idea of being a mage. Feeling the raw power of being able to conjure those planar gateways awoke something in me. There was a thrill in that feeling, and I wanted more.

“I think I want the expertise-magic potion,” I said at last. “I know that something like a warrior would round us out better, but I just can’t imagine myself in that role very well.”

She waved a hand dismissively and grabbed the requested potion. “You’ll be able to fill that gap with another **** at some point. If you feel more comfortable in this role you should do it.” She handed me the potion with a gentle smirk on her lips. God, I was really falling for that cute half-smile.

I took the potion, uncorked it, and poured it into my mouth. It tasted… like nothing at all. There was the faintest hint of something there, something tart, but not unpleasant. It bubbled in my mouth—almost like a soda—and as soon as I swallowed it, I felt different. Just like when I had been in the void, the knowledge just bubbled up into my brain like it always had been there.

The thing I became immediately aware of was perfect anatomical knowledge of Astrea just by looking at her. I knew with certainty exactly where her heart, lungs, spine, and pretty much every other hidden or obscured part of her body was. On top of that, I knew exactly how much pressure I would need to apply to those areas in order to cause the most pain or to shut down that area’s nervous system entirely.

But I also had different knowledge, something a lot more exciting. Magic. It was an intuitive sort of knowledge, rather than a studied one. I just sort of knew that rather than use my own strength to strike at a **** part of Astrea’s body, I could direct a sharp flow of magic to do it for me. All I would need to do was touch that part of her body and a magical current would flow into her and do the rest.

“Whoa,” I said.

“How do you feel?”

“Powerful,” I replied, looking down at my own hand. I didn’t just understand Astrea’s anatomy, I understood my own way better than before too. I felt like I could just… yeah… yeah! A pleasant, tingly feeling crawled up my arm from my core and into my hand. When it reached my fingertips there was a small spark and suddenly a flame was hovering above my palm, burning without any fuel source whatsoever. I could control it telekinetically, and watched with wonder as I directed it to spin around my hand. Yeah!

This was amazing, but I felt like I could do more. I snapped my fingers and the flame changed into an arc of red lightning that danced around my forearm for a few seconds, filling the air with a crackling noise. Then I closed my palm into a fist and the energy dissipated, leaving no trace besides the smell of ozone in the air.

“Haha,” I laughed, grinning, “I can’t believe this is real.”

“It seems you have gained the school of Kinetomancy, just like me.”

“It might be more than that too. I feel like I understand my planeswalking power a little better now. Like it just clicked for me. What school of magic would something like that fall under?”

Astrea considered it a moment, “The ability to bend space and time to your will is Conjuration. I suppose that one was to be expected given that you already had a spell-like power of that persuasion. And what of the expertise side of things?”

I grinned as a thought occurred to me, “Want me to show you?”

“Sure,” she replied, quirking an eyebrow.

I walked closer to her and reached out, placing my fingers gently over one of her nipples. All I had to do now was… right, just like this. The tingling sensation from earlier returned, traveling through my arm and into my fingers. I felt the energy leave my fingers and flow into her breast, and as soon as it did, there was a soft pink flash and she jerked in place.

She moaned loudly, and leaned on the table behind her for support as her legs almost gave out. Her nipples suddenly exploded with milk, shooting out almost violently and spraying me with impressive ****. It didn’t stop there, her hips were twitching and jerking wildly, and she was moaning deeply as what appeared to be a cascading series of climaxes slammed into her almost all at once.

This continued for about half a minute before it finished, and she was left a panting, leg-quivering mess.

“Sorry, I guess I put a little too much into that one,” I said, sheepishly scratching the back of my head. But it was weird, because I didn’t feel like I had put that much energy into it at all. My new instincts were telling me this reaction should have been more subdued.

She shook her head, “N-no, I should have probably told you at some point that I made my breasts more sexually sensitive with Transmutation magic a long time ago.”

That explained it. There wouldn’t be any way my knowledge of her anatomy could have accounted for something like that. “Noted. Are you okay, though?” I reached out a hand to help steady her.

She almost eagerly grabbed it and kept it there as she stabilized herself. “More than okay, that felt incredible. So, I’m guessing that was to demonstrate a keen knowledge of anatomy, then?”

“Yep.”

“You certainly got the point across,” she chuckled.

After letting her recuperate for a moment, during which time we casually flirted back and forth, she gave me a few more potions she had prepared ahead of time. They were pretty standard things one might need when becoming an overnight adventurer. There was one that improved my stamina, one that improved my overall bodily strength without altering my current musculature, one that would let me get a full night’s rest after just four hours of sleep, and finally one that made me need to eat and drink less. Alchemy sure was cool. For good measure, she also provided me with a few healing potions just in case.

“Just because we can’t die permanently doesn’t mean we can’t be harmed,” she reminded.

Then she showed me the item she alluded to earlier, the one that would make returning to this universe easier. She called it a Return Stone. It looked like a glass sphere, not unlike the ones that followed her around outside, but this one was only about the size of a tennis ball, had a soft pink color, and at its core was a peculiar symbol.

“What’s that symbol?” I asked.

“That’s this world’s Rune Key. It is linked to this world, so anytime we want to return here, all you’ll need to do is activate your planeswalking power while holding it. You won’t even need to visualize anything.”

“How do you know it works?” I asked.

“Well, I don’t really,” Astrea admitted. “But I have a hunch it will work. Back on my world, Conjurers would use something similar to instantly teleport back to specific places they’d visited. It’s based on that magitech and I’m just kind of assuming it will work. If it doesn’t, well, at least you’ll have the symbol right there to do it the other way.”

“I see, it might be pretty handy then. Can you make more?”

“Oh yes, the process is easy albeit tedious. It’d take me a week and I’d have to be in the universe we would want to return to. But if we find a universe we really like and think we might want to return there on a semifrequent basis, we may want to consider making Return Stones for them.”

“That’s a good idea,” I agreed.

“And,” Astrea relaxed, folding her arms under her bust, “that about does it for the prep-work.”

“Oh, are we ready now?” I asked.

“Pretty much. I have some supplies prepared that we can bring with us, all we need to do is discuss our first move. I know you have an overall goal, but I was curious about what you had in mind for our first foray into the unknown.”

I thought about it for a moment, “Let’s go out into the living room and discuss it there.”

“Yes, Mistress.”

We walked out into the living room and took a seat on the sofa. I then directed her to sit beside me. She did so without question or complaint, immediately wrapping our hands together and nestling in closely. Her large breasts were pressed against my arm, and her free hand began idly jerking off my cock. She wasn’t doing it with any intent of bringing me to orgasm, it seemed, just to make sure I was comfortable; and I was.

After a few minutes of quiet contemplation, I finally said, “Well, let’s lay out what we know. As much as I would like to, we can’t completely relax. We’re free to do whatever we want, obviously, but there is one responsibility we cannot shirk.”

“Your **** quota, right?”

“Yeah. Veshra didn’t tell me what she would do if I missed that quota, but I’m frankly pretty terrified of finding out.”

“Understandable,” Astrea nodded. “What is your quota, exactly?”

“Thirty per year; and my intuition is telling me that it’s based on this planet’s calendar, not mine or yours. Do you know how all that works here?”

“I do, in fact, tracking the months and years is fairly easy. Each new moon is a month, each month is twenty-eight days, and each year is twelve months. I believe that means three-hundred and thirty-six days in a year. That’s how I’ve been tracking it, and I’ve used divination magic to confirm the planet’s position relative to the star it orbits.”

“Oh, so not too dissimilar to my own world. Okay, that makes things a little easier; it’s almost like this planet was designed to make tracking the calendar easier.”

“Perhaps it was, who knows? Veshra may have created this planet specifically for us.”

“I hadn’t considered that—it’s an interesting thought. Anyway, we have three-hundred and thirty-six days to meet our quota, then. And you said that you are already my ****. Does that mean you already have a mind-serpent in you?”

Suddenly, she stopped stroking my dick and brought her hand up to the side of her head. Her eyes closed, she nuzzled her palm, and smiled. “Yes, I feel him there. I assume he arrived around the same time you did, and the sensation of having him attach himself to my brain was strange, but I’m actually happy he’s there. I feel so warm and fuzzy whenever I think about him.”

That was interesting, a little weird, but kinda cute in its own way. I went on to explain exactly what the mind-serpent was and how we would get more of them. I also explained that we only have one additional egg at the moment.

“So, we have to be careful about how use it at first,” I said. “We’ve gotta make it count, because—and I’m not sure how I know this—new eggs will be laid basically every third new moon on this world, specifically. I guess this is regardless of when the mind-serpent is gained, so all of my slaves will always create more eggs on the same day. This means that the first batch from you will be two new moons from now. At which point, your serpent will lay somewhere between three and eight more eggs and only then will we have a little more wiggle room.”

“Seems like we’ll have a lot once the ball gets rolling,” Astrea observed, seemingly not at all bothered by the insinuation that a bunch of snake eggs would get laid in her actual brain.

“Oh yes. Which is good, because rather than giving slaves to Veshra, I can also just give her spare eggs, but I’d have to give three hundred to her in order to cover the quota—the eggs only count as one-tenth of a ****.”

“So, what’s our first step then, Miss Percy?”

I spent another solid minute or two in silent contemplation, all the while Astrea continued gently stroking me, maintaining a solid erection through the whole thing. Finally, I said, “Step one, we need to round out our team. We’re gonna need a quick and easy way to use my other egg, and we’ll need to pick someone that will complement our combat abilities. You and I probably have magic covered, and I think I can be sneaky and flexible if I need to be, so we need someone with some brawn. Someone with martial capabilities.”

“Sounds reasonable. Then what?”

“Then we think about money. If we can get our hands on some gold coins from any of the worlds we go to, you can use your Transmutation magic to shape them into any other kind of currency, right?”

She nodded, “Indeed. It would be trivial.”

“You’d be like an exchange bank, pretty useful. So, I think after we get another member in our team, we go to a world where we can make money.”

“You do know that it would be a relatively simple task for you to use your planeswalking ability to open a gateway into a treasure hoard, right?”

“That’s true,” I shrugged. “But where’s the fun in that? I wanted this power to go on adventures. This sounds like it would be much more fun, right?”

“I agree,” Astrea nodded. “I was only making sure you were aware of that option.”

The gesture was greatly appreciated. “So, in your forays into the wider multiverse, did you come across any worlds that would be good places to find willing slaves?”

“Oh there are many places like that,” Astrea smirked, “but one place did immediately jump to mind…”
