Zouken's Punishment

As Sakura arrived outside the Matou household, with Rider in her spirit form. This place always looked frightening to her, even before she first entered it when she was a little girl. Maybe it was because her family sent her that made it scary at first. It didn't help when she learned what was inside. She remembered the first time Zouken tossed her into the worm pit for her first 'lesson'. She remembered screaming for hours for someone to help her. For her father. For her mother. For her sister. For anyone. But no one came. Just thinking about it now made her skin crawl.

Seeing the expression on Sakura's face, Rider gently placed her hand on Sakura's shoulder. "Sakura," she said as she materialized next to her. With that, Sakura remembered why she was here and how she could put an end to it. With the notebook and Rider, she can stop all of it. Starting with the man... no monster who started this all: Zouken Matou.

"Thank you, Rider," Sakura said as she readied herself. Taking a deep breath, she advanced towards the front door. She took out her key, unlocked, then opened the door. Inside, the house was quiet. It usually was like this, since only Sakura, Shinji, and Zouken lived there.

Sakura looked around the foyer and saw no one there besides her and Rider. Walking forward, they headed for the study, since it was one of the places Zouken would likely be at when he was in the house. Arriving at the door, Sakura opened it, trying to to seem afraid while doing it. As the door opened, Sakura looked through the opening as it grew to see if anyone was there. When the door was fully, Sakura stepped into the study and saw it was also deserted.

Sakura and Rider continued to comb the house for Zouken, but there was no sign of him on the surface floors. "That leaves one place," Sakura said to herself quietly. She had hoped that she wouldn't have to go back there again, but she had ****.

Sakura and Rider proceed for the basement stairs. Walking down the stone stairs, they entered the worm pit. Along all of the stone walls of the pit were what looked like windows, neatly arranged in rows and columns. Behind each of these alcoves looked like an endless abyss, but Sakura knew better, not that it made it better. As they reached the bottom of the stairs, a voice called out.

"Sakura, what are you doing?"

On the floor of the basement, a swarm of worms gathered and piled up to form Zouken's body. The old stared angrily at Sakura. "I thought I made it clear with Kariya," he growled at her. "Don't disobey me."

Raising one of his hands up, he gestured towards Sakura, causing more swarms of his Blade Wing Worms to advance on her. Just the the worms were a foot away from her, they stopped and hovered there.

Zouken was puzzled. He repeated the gesture, but the worms did not move any closer.

"I guess I will deal with you myself," he said as he dismissed the worms.

"Freeze Zouken!" Sakura proclaimed, like she was casting a spell in a fantasy game. The instant the words left her mouth, Zouken froze in place, as if paralyzed. He tried to speak, but all that came out were grunts and moans. Despite that, Sakura had a pretty good idea what he said.

"'How did I do that?'" Sakura said mockingly.

"It doesn't matter how I did it!" she yelled at him. "You're not the one in charge anymore." As she spoke, her voice became more confident. "And now, I am going to punish you for what you did to me!"

Reaching into her bag, she pulled out the notebook and wrote:

Zouken Matou will revert back to his human form and cannot disperse into worms again. His human body will become a young woman's that appears attractive to Sakura Matou. In this new form, Zouken Matou's new name will be Zou. She will be Sakura Matou's sex **** and will obey her at all times, even outside of sex. She will not be able to perform magecraft unless specifically ordered to by Sakura Matou. She will not be able to tell anyone who she used to be or that she was changed into this form. Her body will make her crave sex. This craving will not go away with time. Instead it will get stronger until she begins to satiate it. When she is having sex with others, she will act as if she is their sex **** and do whatever sexual acts are requested of her. She will only be able to cum once her master(s) have cum, and only once for each time, unless her master(s) order her to cum. After Sakura Matou leaves the Matou household, Zou will put on one of the slutty costumes belonging to Sakura Matou and will leave the house for the night to look for people to fuck her as a prostitute. She will not charge anyone for having sex with her. She will continue to do this until the following evening, where she will present herself to Sakura Matou at the Emiya household.

As soon as Sakura finished writing, Zouken's body began to change.

His back and neck straighten out. His skin shifted to a pale white. The wrinkles on his face melted away, leaving soft, smooth skin. The shape of his head distorted from its old and ugly look, to a rounder, more feminine and attractive. His chin pulled in a bit and rounded out more to fit in with the changes. The nose shrank a bit and his lips became lush and full. Blue hair sprouted from the top of his head and fell down behind his head. The strands stretched down to his shoulders, which were becoming less broad. His arms lost all of their hair and his fingers became longer and more slender.

His clothes, which were a part of his body disappeared, revealing his genitalia had already disappeared and a labia was forming, while his pubic hair fell out. The hair on his chest also popped out, followed by his chest inflated outwards, forming a nice pair of big breasts. This stomach cleared out and shrank, as his hips stretched out.

And within less than a minute, the old Zouken had fully transformed into a young woman. Despite still being frozen by Sakura's earlier command, Zou's body was quaking in fear at what just happened. Sakura smiled at the result of Zouken's transformation, before turning to quickly go back up the stairs, leaving Zou in the worm pit.

Sakura swiftly made her way to her room and started packing. There wasn't much to pack. It was pretty much only clothes. She did make sure to get some of the sexy lingerie she had. Now I can use these for someone who loves me, Sakura happily thought as she packed them. She managed to fit everything she needed

Carrying the bag, Sakura returned to the basement entrance. Placing the bag down, Sakura walked partially down the stairs to see Zou still frozen there. "Unfreeze Zouken," Sakura said as she looked down at Zou. As soon as Sakura said that, Zou collapsed to the floor, panting.

Sakura turned to go back up the stairs to leave. "Now be a good naughty girl out there tonight, Zou," Sakura called back before leaving the basement.

As Sakura and Rider left the Matou household, a young, blond haired man watched them. He was wearing a black biker outfit, with the jacket open to reveal a white undershirt. His red eyes narrowed as he focused on Sakura. "How strange," he thought to himself. "I no longer see the Black Grail inside her. What did she do?"
