Yup, and some changes for Sakura

Sakura got dressed for school, having brought her uniform with her when she ran from the Matou house. She smiled as she walked along side Shirou, her owner. She shudders as the happy thought. It wasn't long before they arrived at the school. Sakura showed the writing that she was Shirou's Property to everyone she passed. Rin had a surprisingly large reaction to this, blushing before looking over Shirou, unhappily. "You had better treat her well!" She said before strutting off to class.

After entering the classroom and sitting down, Taiga ran in and tripped on the way in before getting up. All in all, class wasn't much different. Sakura took some notes, but also idly wrote her name on her desk with the magic sharpie. It was distinctly her property, as she was now keenly aware, but since she was Shirou's property, that meant that it was his by proxy. Realizing this, Sakura started getting ideas. How far could she push this...

She tried it out on her other arm. Sakura Matou's. She was co-owned by Shirou and herself. It was an odd feeling, being keenly aware of who owned you and how, especially when that kept changing. She added a word after Shirou's briefly. Shirou Emiya's breasts. Now she owned herself, but Shirou had exclusive rights to her chest. wiping off the breasts part, she tried working with her own name for a bit. Sakura Matou's breasts. She now had partial ownership of her breasts while Shirou had rights to her everything. She tried editing it again - this was starting to become fun. Sakura Matou's breasts and confidence. Suddenly, she also owned her confidence, she could tell herself how confident to be at a moment's notice! What should she do-

"Sakura?" Shirou had shaken her hand, looking her in the eyes. "Please calm down, you're causing a bit of a scene." Looking around, she could see Taiga frowning as a number of student's wondered what she was doing. Blushing a bit, she rolled her sleeves up and put her new sharpie down. She could play with it later.

Rin was more distracted than usual today. First her clocks had been off by an hour, so she had come in an hour early. She had a Grail War to finish preparing for, and now she learned her sister wasn't adopted by the Matou family anymore, but instead of this no-name high jump kid named Shirou Emiya! And now, she seemed to be losing a bit with writing on herself for several minutes! After Shirou got her attention, Rin decided to get a closer look with her Reinforcement magecraft. Channeling it through her eyes, she got a good look at the forearm that didn't have Emiya's name on it.

Sakura Matou's breasts and - oh come on! Her sister just HAD to cover it with her sleeve right as she was looking. She turned back to the front of class, head on her hand. Well, at least Sakura owned her breasts, so she could try and say no if her owner wanted to play with them....
