Y/n was 14 years old when she got dragged along by her mother. She had a boyfriend for a year now and they decided to live together. Y/n didn't mind on having a new father but it's his son that she couldn't stand. He looked really ugly with his hair flattened and big glasses on. And he is the smartest of our school. A total nerd.

When they arrived, her stephfather and stepbrother were already waiting for them at the entrance.

"Son? Can you please say hi to them?" His father asked with a annoyed tone. He looked at Namjoon, forcing him to say hello. "Hi" Namjoon said while rolling his eyes.

He then swifted his gaze from her mother to Y/n. Inspecting her from head to toe with one corner of his mouth up and scrunched nose.

"Can I go now?" Namjoon asked with a big sigh. "I still have homework to do." He folded his arms and began tapping his foot, waiting for his dad to answer. "Of course son." He said with a content smile.

Namjoon turned around and midway the stairs his dad stopped him. "Wait! Can you carry Y/n's suitcases to her room?" He took Y/n suitcases and pushed it towards the bottom of the stairs. "Yes, dad." He sighted again and still did what he was asked.

He may be polite but Y/n saw that he didn't want to do it. She followed him behind and he suddenly stopped. "Here is your room." He said while turning around without looking at her.

Over the years they grew closer to each other. They acted like real step siblings but for Namjoon it wasn't really like that. He started teasing Y/n. Not what brothers and sister do but in a sexual way. He slapped her bum or poked her breasts. He even kissed her on the lips just for his pleasure. Y/n was very annoyed by it but she didn't dislike it either. 

After a couple of weeks of teasing, Namjoon suddenly stopped doing it and Y/n didn't knew why. He kept his distance from her and she really wanted to know what was going on. She gathered her courage and knocked on his bedroom door.

He didn't answer so she opened it and peeked inside while calling for him. "Namjoon, are you here? I need to talk to you."  But Namjoon didn't answer again. She saw him sleeping on his bed and with mouse steps she approached him. Very gentle she sat down next to him on the bed, not far away from his face. She began to study his face features really closely. His soft lips that were slightly apart so that he could breath. His dragon eyes with long eyelashes.

"When did he become so handsome?" Y/n tought by herself while smiling. She couldn't resist but to lean over. She wanted to kiss him on these soft small lips. But when she almost touched them, his eyes shot open. He grabbed her by the shoulders and flipped her onto his bed. One of his legs between hers and slightly touching her core, making her gasp. He was staring at her and had an intimidating look.

"What do you think you are doing?" He asked her before biting softly on his bottom lip. He repositioned his leg that is against her womanhood and again she let out a soft moan. He knew what he was doing and wanted to tease her a bit more. One hand that was on her shoulder moved slowly down brushing her body all the way down to her core. He carressed it very lightly but enough for her to curl her back.

But then he stood up and went to his door. He told her to leave. Yep! Just like that. "Yah, Really what's wrong with you!" She sounded annoyed but still stood up from the bed. "I'm tired. He responded with a big yawn.

He pushed her on her back, telling her again to leave his room. He closed the door in front of her nose and suddenly Y/n realised that she forgot to ask him why he avoided her in the first place. But then on second thought, is he? 

Namjoon knew that she liked to being teased by him and even though he also wanted more, he restrained himself. He wanted to build up her desire for him.
