Some quick notes

Shirou and Sakura relaxed in the tub for some time. They occasionally made out and Sakura encouraged Shirou to play with her body. Eventually, it came time to get out.

"Shall I dry you off, master," Sakura offered as the two climbed out of the tub.

"N..no thank you," Shirou replied nervously. I'm already hard with what happened in the tub, he thought to himself. And with what happened when we were cleaning...

With that, the two grabbed dry towels and began to dry themselves. Shirou was anxious to finish. He had been holding himself back while they were bathing. He thought he might be able to last a bit longer, but did not want to risk it. And there was something he wanted to do first.

Once they were dry, they wrapped themselves in towels. Shirou took Sakura's hand and quickly lead her out of the bath room and to his room.

As they passed the living room, he spotted Saber sitting at the table. She probably noticed them, but did not react.

Once they were in his room, Shirou closed the door. Turning back to Sakura, he saw she had dropped her towel and was standing in front of him completely naked.

"Shall we start, master" Sakura asked, clearly excited. Shirou had to stop himself from saying yes. "There's something I need to do first," he said as he made his way to his desk.

"What are you doing, master?" Sakura asked as she saw him open the notebook on his desk. "There are a couple of things I want to write for you and me," Shirou explained as Sakura looked over his shoulder.

Shirou Emiya's cannot impregnate a woman unless he want to.

"That's a good idea, master," Sakura commented. "That way we can continue our sexy time." Inside, she was a little disappointed. It would be nice to have master's child, she thought to herself. But then I wouldn't be able to server him as well as I can now.

As Sakura pondered on that, Shirou wrote another line in the notebook. Sakura snapped out of her thoughts when she saw what he wrote.

Whenever Shirou Emiya has an orgasm nearby Sakura Matou, she will also have an orgasm. If she is already having one, the sensation will be added onto it.

"Master..." Sakura said when Shirou finished.

"Sakura," Shirou began. "You maybe my sex ****, but I want you to feel the same amount of pleasure I do when we are together."

Looking over his shoulder, Shirou could see Sakura's face light up with a bright smile. "Thank you, master," she said as she leaned closer into Shirou, her chest pressing against his back and her lips near his ear. "That means so much to me," she spoke softly into her master's ear.

"Master, my I write something for you in the notebook?" Sakura asked timidly. "Sure," Shirou said before he moved to the side, giving Sakura room to write on the notebook. Sakura slide in front of the notebook, rubbing a bit against Shirou as she did. He handed her the pen he had been using. She thought for a moment, pen raised to her face while considering her wording. Then she put the pen to the page and wrote:

Shirou Emiya will have the sexual stamina to last as long as his partners.

"That will be helpful," Shirou said, thanking his thoughtful ****. "But 'partners'?"

Sakura put down the pen onto the table as she turned to face Shirou. "That can wait for now, master," she replied. She struggled a bit with telling her master the reason right now. I guess because he didn't order me to, I can get away with not telling him, Sakura thought.

"Before that, why don't we try out the new changes?"
