Magical experiment - unlocking 2nd sphere

Maximilian knew he had affinity to four spheres of magic. Enki had said so. The first one to be active was the Holy sphere which allowed him to heal himself and others. And based on his experience, admittedly limited as it was, his Holy sphere was more powerful than usual. The evidence was clear: healing his hangover, healing the laundry crone and then healing the geriatric nobleman at Meadows in one go. Though of course he could not be sure whether other healers, men older and more experienced than him could pull off the same feats. But that did not concern him overly much, it was not like he could monopolize healing magic in any case. What he was concerned with were the other three magic spheres he had inside his astral body. What were they and how could he activate them?

"Anna, move to the other bench so that we are facing each other. I want to run a magical experiment and I need your help", he commanded and the brunette immediately complied.
"How did you activate your Divination sphere?" Maximilian asked. His Holy sphere had been active already by the time he took over Max so he genuinely did not know. But Anna did. She looked slightly bewildered to be asked such a question but still answered.
"You need to meditate until you can observe your astral body. Then you can start pushing mana through the sphere you have to objects or your environment until it clicks. I guess that's the best way to describe it", she explained.
"So, it's literally trial and error?" Maximilian was bewildered, he had assumed that there was some formal, perhaps even a ritualistic method to it.
"Yes. I learned that my sphere was Divination when I channelled my mana through my sphere into my eyes and suddenly, I could see living beings through walls. Surprised me for sure since I saw my father taking my mother from behind in their bedroom", Anna giggled at the memory.

Maximilian nodded in understanding. He was not certain how much he could share with Anna. Perhaps he should take a leap of faith and confide in her. She seemed infatuated with him and was certainly eager to please. And as much as he enjoyed her body, he was not comfortable treating her as just a blowjob machine.
"Okay so, the reason I am, well we, are going to Labyrinth, is that just before our graduation, Enki visited me. Well, he summoned me to his plane. Well, it was a dream. I mean, I guess when I was sleeping, Enki pulled my astral body to his plane. I know it sounds insane but it's the truth", Max stammered out, worried how Anna would take it but the brunette merely smiled and nodded for him to continue.
"He told me that I was his champion and that I had to journey to the Labyrinth to solve its mystery or something like that. He was vague about the details. But he also told me that I have four affinities of magic. And when I meditated at school and discovered my astral body, I saw those four spheres inside me but three of them are still inactive", Max explained, gaining more confidence thanks to how attentively Anna listened to him.
"So, you'd like to experiment on me to see which spheres you have", Anna stated and Maximilian nodded. He had not said anything about originating from another world, that was probably too much for even Anna to believe.
"Do you have any advice how I should proceed?" He asked.
"The elemental spheres are easy, just focus on creating a little bit of each element. Like conjuring a drop of water or a pebble. If those don't work, then you know that all your spheres are complex ones. Evocation is probably easiest to do, try shooting a bolt of energy at a passing tree or something. Abjuration is simple too, try making a **** field between us. And for Divination, well, try sensing the driver through the roof of this carriage. It's all about focus and imagination, there's no secret words or anything", Anna explained. After hearing all this, Maximilian was glad that Anna had followed him and that he had picked her up.

"Okay, here I go", Max said and closed his eyes. He concentrated inwards until his astral body became visible and the spheres of magic with it. His healing sphere was large and glowing with golden light after all the sex he had had with Anna. The three dark spheres were small in comparison. He imagined pouring mana over them and then that mana streaming from them, emerging into his open palm in the form of a little pebble. Nothing. Then Maximilian imagined a droplet of water. Nothing. A spark of lightning. Nothing. A tiny flame. Nothing.

"Well, none of the four elements worked", Max announced as he turned his attention outside the carriage. Re-focusing, he aimed one hand at a tree they were passing and imagined shooting it with raw mana. Nothing happened.
"That's no for evocation", he admitted. Next was divination but despite concentrating as hard as he could, the roof of the carriage refused to yield.
"And a nope for divination", he told Anna.
"Keep trying sir", she encouraged him and Max nodded.

Eyes closed once more, he poured more mana over the spheres and imagined it flowing out of him, forming a shield between him and Anna. This time things happened - he could feel the power leaving his body and when he opened his eyes, the air shimmered right in front of his eyes.
"Well done sir! You created a shield!" Anna exclaimed and clapped her hands. Maximilian turned his gaze inward once more and, sure enough, a second sphere had indeed activated with silvery glow. Excited, he poured more mana through it. It was weird, he could sense the shield forming right in front of him despite there not being anything.
"Hmm, it must be that the mana forms the shield on the astral plane or whatever you call it, yet it extends to the physical world", Maximilian mused out loud, causing Anna to nod.
"Yes, that's how the teachers explained it. Abjuration is not actually creating anything physical, that requires Evocation or Conjuration, but Abjuration has an effect on the Material Plane too", Anna told him.
"Let me try something", Max announced and focused on the shield. He imagined it being polished like a mirror until it gleamed.
"Okay, try detecting life now Anna", Maximilian commanded her and Anna furrowed her eyebrows in concentration.
"That's weird, I can't see you. I mean, I can see you, you're sitting right there on the bench, sir, but my Divination just shows myself and nothing else", Anna exclaimed.
"How did you hide yourself like that?!"
"I've seen movies, it wasn't difficult to figure out", Max grinned happily.
"Movies?"
"Ah, never mind that. I want to try unlocking the other two spheres", Max hastily said, directing her attention away from his unfortunate word-use.

But when he tried to pour more mana, he realized that his tank was running empty. He had spent too much mana in his experimentation - both the gold and silver spheres were tiny and dull. Well, there was a fun solution to that problem!

"Come here and serve me, wench", Max ordered, exaggerating his words as he opened his breeches. Anna nodded and slid to her knees between his legs, eagerly capturing his manhood between her pale pink lips.
