"You read a book and it tells you how to shoot sparks out of your fingers, that's the test."

"It looks easier than our sorcery when you do it. Man, now I really hoping Henry will be able to learn it."

"Of course you do," Henry says, but he pats Gabe's butt.

Ari does too. Having hands again is fun.

"So you wouldn't even want to learn that for yourself? That seems crazy."

"Maybe for the less intense stuff. But I don't actually like causing pain on myself? The fun of pain is someone making you feel it."

"What about causing it to others?" Ari bats his eyelashes as best he can.

"What kind of partner I would be if I didn't please a man in every way I can?" Gabe says. He plays with Ari's nipple and twists it.

"You know, this is a refreshing change of place from my brothers," Thomas stage-whispers to Henry. "They would hear 'shoot sparks' and immediately try to calculate how to create a power-plant around the concept."

"What's a power plant?"

"Like, the smartphone and some other devices use electricity to work. A power plant is place where we create that electricity."

"Oh, for lots of electricity you want chain lightning. But you need to know the lesser magic before you can learn more powerful magic, so you'd still be starting with Sparks."

"Cool and you can still use it to be a bad ass demon-slayer!"

Ari nods.

"But we were going to talk about your kind of magic! And Gabe was going to go do other stuff for some reason."

Gabe teasingly tugs Ari's hair because of the slight jab and leaves.

"Yes, we were. While you were distracted, I was planning the next lesson. A practical ritual casting. An unusual take on a heat resistance ward."

He deliberately looks down at Ari's dick to indicate why that particular choice of ward.

"Ah! I'm told that's a good idea. So how do we do it?"

"I think we can combine two rituals. One for heat resistance and and one that stops sexually preventable diseases from spreading through semen. We take the two rituals and figure out how to cannibalize them into something viable and not too lifeforce extensive."

He already has the relevant books out.

"There is a condom ritual??"

"Ooh, learning by doing. I like it."

Henry grins.

Thomas still is a bit in shock it took this long for him to learn that the "condom ritual" existed. But he helps, there is a planning bit where they have to figure out how to make the two rituals go together.

Thomas offers the insight that maybe Ari still wants to retain the "prevents diseases" aspect of the ward, so they might as well keep it.

"I have a necromancy trick that kills disease, but never getting it in the first place does sound more tidy all around."

Henry nods at the two of them. "And it should make the new ritual easier to plan."

And they set about doing that. With Henry explaining what each part of the ritual does and how it contributes to the overall thing.

Then put the theory into practice!

Ari casts the ritual as directed.

"I wonder, how would one test that it worked?"
