The next day, Takeru stopped by Nijou-sensei's office to get checked out and have his bandages replaced.

"You're doing better than I had expected, Oyama-kun." She said while replacing his head bandage.

"Thanks, I owe it all to you, Nijou-sensei!" He said, smiling and blushing while looking at her enormous cleavage that was in front of his face.

Nijou-sensei giggled. "It's amazing you didn't get a concussion. Make sure you eat well, drink plenty of water, and get enough sleep. If you do these things, you'll get better in no time. And once you're better make sure you start training. You promised me, Oyama-kun."

"Yes, sensei, I will. And I'll start training as soon as I'm better." He said, still blushing and staring at Nijou-sensei's cleavage.

The following day, Takeru was in much better conditioned and he began his training. He continued with his training for the next weeks, all while keeping up with his studies, as well. During that time, he would stop by Nijou-sensei's to have small chats. He began to feel more comfortable with her than with anyone else he had ever met. With Nijou-sensei, he could be himself and ask her for advice on school, training, and life in general. She also felt the same way with him, and was there to support him in anyways she could.

School had ended for the day, and Takeru went to visit Nijou-sensei's, since he hadn't done so at the beginning of the school day.

"Hi, Nijou-sensei." He said, smiling, as he opened the door.

"Oh, hi, Oyama-kun." She smiled back at him. "Going home for the day?"

"Yes. I just dropped by to tell you my training is going well and I got a 98 on my exam, that highest in my class."

"That's wonderful! I see your training is going well, you look great." She giggled.

"Oh, thanks." He blushed.

"How about I treat you to a nice home cooked meal to celebrate your achievements?" She said, smiling cheerfully.

"Really? That would be great! I love your cooking!" Oyama said enthusiastically. He remembered the time he had been handcuffed to her and how they had spent the weekend at in a cabin at an island resort. During their stay, Nijou-sensei cooked some of the best meals he had ever eaten.

"Well, then I'll see you in an hour." She said. "Here's my address." She wrote it down on a piece of notepad paper and gave it to him.

"Ok, I'll see then. And thank you, Sensei." He said grinning, and left the office. He ran all the way home, excited he was going to spend dinner with his favorite sensei.

"I better finished up in here, otherwise I won't be able to get dinner ready on time." Nijou-sensei said to herself, as she started to put away papers and various medical supplies.

Takeru Oyama arrived on time at Aki Nijou's apartment. He rang the bell and was greeted by Aki's voice.

"Coming in, Oyama-kun!" She said over the intercom door speaker.

Takeru opened the door and went inside. He could smell a delicious aroma coming from the kitchen, as he began to change his shoes to the guest slippers that were in the shoe rack that was next to the door. He went into the kitchen and saw Aki wearing an apron, cooking tonight's dinner.

"Hi, Nijou-sensei. These are for you." He said, as he handed her a bouquet of flowers.

"Oh, Oyama-kun! You shouldn't have. You're making me blushed." She said, surprised at his warm gesture. She grabbed them and placed them in a spare vase.

"Dinner smells incredible." Takeru said. "Do you need any help?"

"No, thanks, Oyama-kun. You're my guest so don't worry about anything. Dinner will be promptly served, so go take a seat at the dinning room table." She said, smiling.

Oyama took a seat at the dinning room table. Ten minutes later, Aki brought out the dinner. She had prepared soba noodle soup with spinach; steamed rice; grilled mackerel; boiled vegetables.

"Nijou-sensei, you're amazing!" He said, as he looked at all the delicious food on the table waiting to be eaten.

"Thank you. Oyama-kun." She said, blushing. "Let's eat. Itadakimasu."

"Itadakimasu."

After that amazing dinner, Takeru helped clear the table and wash the dishes.

"You don't need to help me Oyama-kun. You're my guest, after all."

"I want to help. This is the best meal I had for a very long time."

Touched by his kindness, Aki agreed to have him help her wash the dishes.

After the dishes were cleaned and dried, they went into the living room and sat on the couch. They spent an hour talking about school, laughing at the stupid things that went on there, and other various topics.

"I'm happy you're doing well in your training and in school." Nijou-sensei, with a sparkle in her eyes.

"I owe it all to you, Sensei. You helped me to push myself." Takeru said, confidently. "You're a great Sensei and an amazing cook. You're the perfect woman, Nijou-sensei." He said as he leaned forward and kissed her.

Aki Nijou was taken by surprised by what was happening, but she didn't fight it. To a certain extent, she was hoping this would happen. The kiss began slowly, but later it increased in intensity, becoming long, deep, passionate, and filled with desire.

Aki broke the kiss to catch her breath, both of them staring at each other, their eyes saying everything they need it to know.

Aki stood up and grabbed Takeru's hand, and began to lead him away from the living. She opened the door to her bedroom and they both sat on the side of the bed.

Takeru didn't need for Aki to say a word, he understood perfectly well, as he began to passionately kiss her and both fell on top of the bed. Takeru rolled on top of Aki and began to ravish her neck. She let out moans that incited Takeru to become more aggressive, until the point of no return was reached and their bodies became one. Aki's orgasmic screams reverberated across the bedroom to announce Takeru's graduation into manhood and a goodbye to his childhood. Forever.

That night, both joined the ranks of adulthood.
