OC X Yui

Author's note: Yui will be in the real world

Jake found a little girl in the woods, passed out. He was just outside searching for nothing in particular. He was now 16 and just went in the woods to think. He brought the girl back to his place. She couldn't be much older than 10 and just wore a white dress. The only other thing about her is that she had long black hair.

He sat her in the master bed and just read a book while waiting for her to wake up.

"H-Hello." He heard the little girl say to him after a couple hours.

"Hello, I'm Jake do you know you're name?"

"Yui." The little girl said

"Well Yui, do you have a last name?" Jake said smiling at the young girl.

"I don't remember." Yui said.

"Well now what do I do?" He thought. "Going to the police is the natural choice." So he asked Yui if she felt up to walking.

"I should be fine." She said

They got to the police station, the police let Yui stay with Jake since she clinged to him. At least until the police get called about a missing girl matching her description.

Jake just had one question left when they got back to his house. "Yui how old are you.?

"I'm 8."

3 years later

No police report was ever filed for the young girl. So Jake sort of became Yui's dad. She even started calling him Dad. Alas Daddy's little girl was going to take up a whole new meaning sooner rather than later

Now 11 and 19 Yui and Jake are doing normal Father and daughter stuff. Jake was happy but Yui wanted more. Since she saw something the year before

That thing she saw was Jake fucking his girlfriend Rika. Yui apparently woke up to Rika moaning went to Jake's room and opened the door and she saw them. She waited till they were done. Rika had to babysit the next day so she went home. But after they were done Yui went back to her room

Now a year later, Jake works from home. He and Rika stopped seeing each other. Yui never wanted She was to go to school and Jake respected that choice. She was smarter than most kids her age so he never felt the need to make her go to school. He also bought Yui some clothes since that white dress while adorable was getting too small

One day when Jake was working Yui came in to his office. "Daddy can I talk to you about something?"

He usually always made time for his little girl. He looked at her up and down just to see what she wore today. She wore a blue shirt and a pink skirt and like always she was barefoot and just let her hair down. "What is it, Yui?"

"Are you working right now?" Yui asked looking downwards.

Jake patted his lap, and Yui sat there. "Don't I always make time for you?" He kissed her forehead. He's gotten used to being Yui's father figure

"I was watching TV and the show I was watching kept mentioning sex. What it that?" As smart as she was sometimes Jake wished she went to school.

"Well...um… you know how babies are formed right?" Jake asked

"No." Yui said

"Ah geez, well I really don't know how to explain it." Jake said knowing he very well could but didn't think Yui was old enough

"Then show me." Yui said

"No." Jake said quickly. As much tension as he had ever since his break up with Rika. There was almost no way Yui was being a substitute.

"Please daddy." Using puppy dog's eyes. His one weakness

"Fine, I'll be done in a minute. Go wait in my room." Yui ran off while Jake finished. "This one time I'll use Yui but after that I'm done." He thought and he was so wrong.

Yui was sitting on his bed. He sat next to her. "Are you sure.?"

"I am." Yui said.

"Ok." And he started

He kissed Yui. Yui's eyes shot open wide but she closed her eyes and allowed Jake's tongue to enter her mouth. After their tongue dancing he pushed Yui back so she was laying down. They went back to swapping spit as he caressed her thigh. Yui moaned which made Jake's member raise. He made Yui sit up and he took off her shirt and he threw it on the floor. Jake took off his shirt and did the same. He then sucked Yui's little nipple. Which made her moan really loud.

Jake then pulled off her skirt and realized that she was wearing no panties. He took off his pants and underwear.

"Ok Yui, you know what this thing is right?" Jake asked

"It's your penis." she answered Jake nodded

"Alright first wrap your hands around it and move your hands up and down the shaft." Jake said and Yui started giving him a handjob. It felt amazing to him. He just leaned back and enjoyed it. All of a sudden Yui started sucking his dick. Her tiny mouth felt amazing around his cock.

Jake couldn't hold it anymore. He pinned Yui down. "D-Daddy." He inserted his length inside her tight pussy "Daddy. That hurts."

"It's because it's your first time. It'll stop hurting in a bit." Jake said.

He then thrust it in and out of Yui. "Daddy I love this." She said wrapping her arms and legs around Jake. Her stomach would grow every time he was inside her. She then curled her toes and grabbed the sheet. She then came which forced Jake to cum as her walls squeezed his length. He then laid down next to Yui, drained.

"I'm sorry Yui." Jake said. He wrapped his arms around his adopted daughter to give her a hug.

It's okay Daddy. I should be the one to apologize" She said as she wrapped her arms around her father

"Why"

"Dad, did you honestly think I had no idea what sex was."

"Yui, seriously. I'm now very mad at you." But Jake couldn't care less. Yui was the best he ever had.
