Planning around a roadblock

"Good morning, master! Did you sleep well?" Sakura exclaimed as she subtly licked her lips.

"Good," Shirou replied, still getting used to Sakura's wake up call. "How about you? Did you have any trouble sleeping?"

"I slept great, master!" Sakura proclaimed. That's a relief, Shirou thought. I was worried that having her sleep that would be bad for her.

"Master, have you thought about what I suggested last night?" Sakura asked. She tried to hide it, but Shirou could tell she was excited at the prospect of him saying yes. It's still a little weird that she wants me to make a harem, he thought. Not that Shirou would be entirely against doing it. He had some reasons for being unsure were.

First, Sakura herself. Shirou wanted her to be happy and he wasn't sure if making a harem would hurt her or not. She said she was okay with it, but he wasn't convinced.

Second, Shirou was understandably nervous about the idea of making girls his against their will. He had always been a nice and helpful person, never taking advantage of others. In fact, it was usually others taking advantage of him, or at least that is what Issei would say.

And finally, Shirou was pretty sure Saber would object to him doing this. She was still his servant, but she might be able to stop him, even if he used a command spell.

After a moment, Shirou answered. "It's not like I wouldn't want to make one," he begin. "It's just... there are some.. problems. Not to mention, I doubt Saber would allow me to do it."

Sakura looked confused. "Couldn't you use the notebook to make her okay with it, master?"

Shirou shook his head. "I don't know her real name," he explained. "She said since I wasn't a real mage, it would be safer if I didn't know what her real name was."

"I see," she said as she put her hand to her chin as if pondering on this issue. "What if... we use the notebook on her indirectly, master?" she offered.

"What do you mean?" Shirou asked, genuinely unsure of what Sakura was talking about.

"Well, master, with Zouken, I was about to change him into a girl. Maybe we can use the notebook to make a change to you that we can use on Saber."

"But what kind of change would make Saber going along with this?" Shirou inquired.

As Sakura thought, she felt some of her master's cum on her lips. Suddenly, her eyes widened as she came to a realization.

"What if we use the notebook to make it so your cum puts people into a trance?" she quietly exclaimed.

The gears started turning in Shirou's head. "That might work," he spoke out loud. "The book seems to work better on... sexual items. The only thing is how do we use it on..." Shirou stopped when he remembered what had just happened a moment ago. "If we get her to eat it, it might work."

Sakura nodded. "Good idea, master!" she said. "Though, we will have to change the taste and odor so Saber doesn't notice."

Shirou nodded. Yeah, Saber might notice what we are feeding her is semen when she...

He paused for a moment, realizing something. "Sakura, does my cum taste... bad to you?"

"No, not at all," Sakura said defensively while frantically shook. "I... like the taste of yours, master" she finished, trying not to her master think she didn't like it. While it wasn't tasty, Sakura was honest that she liked the taste of his. Even though, it wasn't too different from any other she'd tasted.

Shirou could see what Sakura was worried about. "It's ok," he said as he reached out and gently patted her on the head. "I'll make sure it tastes better for you from now on."

With that, Shirou crawled over to his desk, opened the notebook and picked up the pen. He put the pen to the page and wrote.

Shirou Emiya can make his cum taste and smell like a base ingredient, like honey or syrup.

Sakura crawled up behind Shirou and saw what he wrote. "Now for the trance thing," Shirou said as he tapped the pen against his chin in thought. "We probably don't want it to do that all the time." After a moment, he put pen to paper again and wrote.

Shirou Emiya can make his semen induce a trance on those who consume. While in the trance, the person will do what they are told or answer any questions asked of them.

"How do we know if it worked?" Shirou asked as he closed the notebook and turned towards Sakura.

"You could test it on me, master," Sakura volunteered.
