Give them tips

"What part are you confused about?" Kasha asked the succubi.

Their pointed ears perked up, and they ran over to Kasha. One held her hands up, yellow mess staining it. "The instructions said to break two eggs, but I don't know what to do with this."

"That's a shortened explanation. What it means is that you crack the shell on the edge of the bowl like this," Kasha did so. "Then you let the yolk fall into the bowl and toss the eggshell away."

The red-skinned succubus nodded eagerly, then ran back to her station.

The purple-skinned one asked, "How do I get my fire magic to heat the oven to 350 degrees exactly? I've never worried about how hot it is when throwing before now."

"You don't need to use your own magic. If you use this setting on the oven, it will heat itself to the proper temperature."

With that, the succubus nodded and ran back to her station.

Soon enough, Kasha's preparations were finished, and she was able to put her cupcakes into the oven to bake. That let her step over to the other stations to help the succubi with their ongoing problems.

Finally, the red-skinned succubus finished her own preparations. "Okay, now for the icing!" she said, reaching for the jar.

"Wait!" both the purple-skinned succubus and Kasha said at once.

"You have to apply the icing after its finished baking, you can't do it yet," Kasha explained.

"Oh, I didn't know that!" both the succubi chirped.

"Then why did you try to stop her?" Kasha asked the purple-skinned succubus.

"That's a jar of the chef's cum. She's used her lust magic to refine the taste, texture, and smell. One whiff and you'll be hopelessly addicted. You need noseplugs before you open it," the succubus explained.

Kasha went pale. She'd noticed there were noseplugs amidst the materials provided, in addition to the baking tins and oven mitts. She figured it was in case one of the other students burned something. She gulped. "Well, I'm grateful to you, it seems I'm not the only one here with things to teach," Kasha said nervously, immediately plugging her nose.

Soon enough, her cupcakes were done baking, and it was a simple matter of applying the frosting. If Kasha didn't know better, she'd assume it was just like any other. It seemed what that succubus had said about texture was true.

Decorating them was a simple matter, and all Kasha had left was to present them to the teacher.
