"Irie-kun you idiot! You promised not to tell anyone!"

"Iiiidiot! I lied!"

"That's so mean Irie-kun!!! You are the idiot!"

A week had passed since their trip together, and Kotoko and Naoki were having a small pointless quarrel. This morning, Naoki secretly told Yuuki about Kotoko being ticklish everywhere, so when he and Kotoko came home after work, Yuuki immediately attacked her. Naoki actually wanted to join in, but he didn't want anyone to see him do such an embarrassing thing. Kotoko was saved by mrs. Irie, and she dashed towards their room. And since then she didn't come out anymore. Naoki finally went upstairs too, and found out that she really was mad about it. How stupid, he thought.

"Come on! Okay I'm sorry, it was mean to break my promise, but it's not a big deal is it?" Naoki asked Kotoko, who was sitting on the bed with her back towards him, acting angry. She ignored him. Geez she really was exaggerating, getting all mad because of such a stupid thing. But she was still wearing her nurse outfit, so it actually looked quite funny. He sat down behind her and poked her between her ribs.

"Come on, smile or I'll make you smile" Naoki threatened with an evil grin. Kotoko grumbled and moved away from him. He moved closer to her and squeezed her sides, making her jump. "Stop it!" She squeaked, patting at his hands. He slowly approached with wiggling fingers, and Kotoko backed away. "N-no don't!!" She shrieked when he pushed her down on the bed, and started to tickle the hell out of her. She buried her face in the blankets and tried not to laugh. She wouldn't let him win this.

Naoki watched her fight it, and smirked. "Come on Kotoko, smile for me?" He asked but she still didn't react. He stopped tickling her, and she thought he had given up. But then he lifted her foot, and slowly pulled off her sock. Kotoko lifted her head to yell at him: "Oh no you wouldn't dare!" But Naoki started to tickle her bare sole mercilessly, and finally got her to laugh out loud. She let her head fall on bed again and laughed, squirmed and kicked hysterically. "Aahhahah okay-heheheh I-hahaha I give in! Eeehehehhe n-now staahaaap!!" That's what he wanted to hear.

Kotoko looked at him, and she really smiled again. Maybe it did help. They moved closer to kiss, but then they heard a (fake) cough. They looked and saw Yuuki gazing at them. "Ahem.. dinner's ready" He said, and closed the door again. Kotoko giggled, and Naoki sighed.

"Papa, Yuuki and me will go visit the family after dinner, will you come with us?" Mrs. Irie asked when they were having dinner. Naoki and Kotoko looked at each other and smiled. "No, we'll stay here" Naoki said.

"You can't leave them alone mommy, they'll have sex!" Yuuki said childishly. "Yuuki!" mrs. Irie warned. Kotoko blushed and Naoki glared at his brother. "I promise we'll behave" Naoki said with a serious look. "Kotoko, does onii-chan like it when you wear your nurse outfit?" Yuuki asked teasingly. Kotoko's face turned all red. "W-why are you asking that?!" She asked with a loud voice. "Idiot, because you're still wearing it" Yuuki said and he pointed at her. "Eek!" It seemed Kotoko just realized it. "I-I forgot to change, I had to hurry if I wanted to walk home with Irie-kun and it was busy so…anyway, I'll change after dinner" She stuttered with a blush.

"Well then, bye bye!!!" Mrs. Irie said waving at the couple, and the door closed behind them, leaving Naoki and Kotoko alone in silence. "I'll go change" Kotoko said, and she went upstairs. Naoki thought for a moment, and then followed her.

When he entered the room, Kotoko was trying to pull her outfit over her head, it looked very funny. Naoki smirked at the sight. "Oof! Irie-kun! Please help me, I think it's stuck to my hair clip or something I – kyaaaa!" Naoki had started to lightly tickle her revealing armpits. "Mohh hehe stop that already it's NOT funny anymore Irie-kun!" Kotoko complained as she moved away from him. "Okay okay sorry, I won't do it again" Naoki quickly apologized, and he helped her pull off her nurse outfit.

She saw her husband stare at her half naked body and grinned. "Am I that irresistible?" She asked with a flirty glance at him, and she slowly approached him. "Don't say stupid things!" Naoki said, face red with embarrassment. But Kotoko stood on her toes, wrapped her arms around his neck and kissed him passionately. He kissed her back, and slowly pushed her towards the bed. "Didn't you promise them we would behave?" Kotoko asked teasingly. "I lied" Naoki answered, and he continued kissing her. She started to slowly undress him as they kept on kissing, but then suddenly the door opened. They both looked up very shocked, and saw Kotoko's father, who seemed to be done working earlier. He stared at them and his face turned red. "Eh I'M SORRY!" He shouted, and immediately closed the door behind him.
