Yes, and a discussion on wishes

It was surprisingly out of the way to get to the library, but it was at least on the same floor as the rest of the faculty. Tomas seemed like a kind elderly man, helping him find every book on the list. "Professor, I hear you are lacking in knowledge of the Church of Seiros. The library contains countless documents about the teaching and history of the church. I encourage you to make good use of them." He suggested as Byleth left back to his new room with the books.

Setting them down on the table, he closed the door before looking over the long list of books he'd acquired. Some of them were pretty obvious for him, lessons in Swords, Lances, Axes, Gauntlets, and other things he'd had some training in. Then you had the more mental aspects of combat, like Authority, Reason, books on Faith (all of which featured the church a lot) that he had less familiarity with. And then there was the things he supposed might be taught in a more conventional education (the thing he never really had): Math, Knowledge on plants, fish, economics, et cetera. He had basic knowledge of those, but mostly what he needed to get by, having been schooled by Jeralt.

"This is going to be tricky." He mused to himself, his hand rubbing where he had been keeping the lamp accidentally.

"And I'm here to help!" Sothis declared, shouting as she posed dramatically while shoving her tits right in front of him. It was enough to have him fall over onto his bed. Byleth was worried that someone had heard her, before remembering no one could notice her when she was out of her lamp. "Sothis, I really want to -"

"Try this on your own, Master?" She cocked her head at him before looking over the pile of books he'd gotten himself for teaching. "I see you've got a lot of reading to do then. I get that you want to teach them effectively, Master, but going it alone is going to wear you out if you just try from scratch."

"And how are sexual wishes going to help me here?" Byleth protested, raising an eyebrow. In truth, that was part of why he hadn't made any wishes since they had been packing to come here. Sothis, however, tutted at him. "Yes, my wishes must be sexual in some way, Master. But, they don't have to lead directly to sex. Simply put, as long as they either have some potential sexual use or motive, they count. Even if they also do other, less explicit things."

Byleth took a moment to process that. "So you're saying..."

"Correct, Master~" She leaned over and pressed her impressive bosom against him. If you wanted, I could give you the full contents of all those books into your head if you wished that you would get it by, say, fucking my brains out, or motorboating Manuela's tits." She moved to Byleth's arm, pushing her chest into it. "Or, if you wanted to understand your students better and didn't want to read their minds -" Byleth admitted he didn't, for a number of reasons. "- you could simply get an ability that tells you what a student is good at or interested in, as long as it included something sexual, like say, their sexual preferences or fetishes~" She whispered the last part into his ear, seductively.

Byleth thought about it. In all honesty, they were tempting, and not just because the genie was giving him a boner right now. Having a better knowledge base on some of these subjects could be helpful, even if he did want to improve on some things on his own. And having a better understanding of his student's could be helpful, especially if it was just basic info that he could turn on and off... The question was, how far to go?
