"Malcolm!" Called Agnes and ran through the house that she shared with her brother. Malcolm, who was 17 years old, turned and looked at his sister.

"What's the matter, Ang?"

"Can we do something?" She asked excitedly. Malcolm giggled and looked at his sister, two younger than him.

"Of course we can do that. Are we going to swim at the beach?"

"Yes!" She exclaimed excitedly.

"OK."

"But, Mal ..." She then mumbled softly.

"What is it, Ang?" The boy asked, turning back to her.

"You know, I ... I don't have a swimsuit anymore."

"No bikini either?" Asked Malcolm.

"No." She muttered.

"Well... what do you think of us going to a sports shop and buying you a new bikini? And then we can ride our bikes to the beach."

"Yes!" Malcolm smiled.

"OK. Then pack a bag and we'll meet here in five minutes." Agnes nodded happily and ran into her room. She loved going out with her brother. Malcolm was always there for her. He took care of her when she wasn't feeling well. Agnes packed a backpack in which she packed a lot of chocolate, a towel and a blanket. Also sunglasses and something to drink. She put on her sandals and shorts. Even if her parents always bought her skirts, she hated them. Agnes combed her wild, shoulder-length locks and then ran into her brother's room.

"I'm done, Mal!" She called. Malcolm hopped around the room naked, trying to pull on his swimming trunks. Agnes saw him from behind and looked at him with interest. When he heard his sister's voice he turned around suddenly.

"Agnes! I'm not done!" Malcolm screamed. "Get out!" She grumbled and closed the door again. She thought a little about what Malcolm looked like completely naked. To be honest ... Agnes didn't want to be a girl, she ... she wanted to be a boy. Boys also had it much better. But ... she was a girl! The door opened again and Malcolm came out. He was wearing a t-shirt and shorts. "Why didn't you knock?" He asked. She bowed her head.

"I'm sorry, brother." She muttered to herself. Malcolm sighed.

"All right. Have you packed your things?" She nodded.

"You?" He nodded too. The two went into the garage, got their bikes out, and drove into town, where they chained the bikes in front of a sports shop. Then they both went inside.

"Do you already have an idea?" Malcolm asked, looking at Agnes.

"No. Not really." The two strolled over to the swimwear and then to the women's section. There they stopped in front of a shelf.

"What do you think of that?" Malcolm asked, pointing to a dark brown bikini with light blue patterns. Agnes took a closer look at it.

"Yes. Actually nice, but... no." Malcolm nodded and continued through the shelves. Agnes watched him go for a moment and then checked herself. After a while, Malcolm came back with a salesman. He was around 20 years old and looked like an apprentice.

"What's the problem?" Asked the young man.

"My sister would like a bikini, but she doesn't know which one." Malcolm said, standing next to Agnes. Agnes hated talking to salespeople, but she couldn't send him away now either.

"Do you already have an idea?" Asked the salesman, grinning at her. Agnes glared at Malcolm, who shrugged.

"Her favorite color is green. What cut do you like, Ang?" Malcolm asked. She turned back to the shelf and shrugged.

"I like that." She said, pointing to a dark green bikini with patterns. Malcolm nodded and stood on tiptoe since he wasn't exactly tall. Just like Agnes. Both were pretty small. Malcolm turned to the salesman.

"Thanks for your effort, but we can get on ourselves." He nodded and left again. Malcolm took down the bikini and gave it to his sister. Agnes took a closer look at it. "Do you like that?" Asked Malcolm. She nodded smiling. "Go into the locker room and try it on." Agnes nodded and ran into the locker room. Malcolm waited in front of the curtain. "And?"

"The top is way too big." She moaned.

"Can I look at it?" He asked. She nodded and came out again. Malcolm started giggling.

"What is?"

"It's just way too big. Turn around." Malcolm looked at the note on the inside of the panties. "OK. This is size 42. That is of course way too big. We could try size 32." She nodded. Malcolm turned her back over and looked at the top. "What's your bra size?" He asked. She blushed. He pulled a little on the straps. When there was no answer he looked up at her. "What is your bra size? 75 B?" She started laughing.

"Mal. I don't have 75 B!" She laughed. Malcolm giggled a little.

"OK. Then not. Which size do you have?"

"I ... I have ..."

"Hey, I know your tits ain't big. Don't be ashamed." Malcolm grinned.

"Mal!" She shouted, slapping his chest and blushing. Malcolm giggled.

"Was just a joke. So what do you have A"

"AA." She mumbled very softly.

"Is there such a thing?" Asked Malcolm, eyes wide.

"Yes. There is." She giggled. "It ... it's the smallest bra size there is."

"Okay ... and what extent?"

"25."

"Okay." Malcolm ran off to find something smaller. "What about it?" He asked as he held the two pieces in the locker room.

"Never frighten me like that again!" Agnes shrieked. Malcolm chuckled softly. When she had put it on, she came out of the locker room. Malcolm smiled. God his sister was really beautiful. Her fair skin and ... the way her curls rolled around her ears. Her green eyes looked at him uncertainly. "What do you think?" She asked softly, turning a little so he could look at her. Malcolm smiled.

"It looks good."

"Am I not too fat?" She asked, putting a hand on her hip.

"No. You're beautiful, sister." Malcolm smiled. She blushed. She hated it when Malcolm called her that. But ... well ... she was a girl.

"Thanks, Mal." She mumbled softly.

"What's going on?" He asked, taking her hand.

"I ... I don't want to discuss this here."

"OK. Do you want the bikini?" Malcolm asked. She nodded. "OK. Then change your clothes again. Or... do you want to leave it on right away?" She nodded again.

The two had gone to the beach. They lay on the blanket and let the sun shine on them. Agnes looked over at Malcolm and smiled when she saw her brother's dark chest hair. God. She wanted so badly to be a boy too.

"Mal?" She asked softly.

"Yes? What's going on?" He mumbled half asleep.

"I ... I want to ask you something."

"Yes?"

"Would you ... would you accept me if I were a boy?" Malcolm turned his head and looked at her questioningly.

"What do you think? You're a girl, Agnes You can't change that. That's so. You'll always be a girl." Agnes felt tears welling up in her eyes. She jumped up and looked at Malcolm angrily.

"I hate you, Malcolm!" With that she ran to her bike and drove away. Malcolm looked after her in shock. What just happened?

*

Agnes threw her bike in the garage crying and ran up to Malcolm's room. She locked the door and undressed until she stood naked in front of Malcolm's large mirror. She hated her body. So much. She wanted to be a boy. A real boy. She opened Malcolm's closet and pulled out a pair of underpants, which she put on. It fitted like it was for her because she had the same small pelvis as Malcolm. When she looked at herself in the mirror ... her body didn't look like a girl's. She had hardly any breasts and no or a few curves. She took one of Malcolm's shirts and put it on. Then she undid the top buttons. The way Malcolm had worn it once. She thought it was pretty cool. She pulled on one of Malcolm's jeans. She didn't have real jeans like him. Her parents thought she didn't need that. Real jeans, would be for boys. But that wasn't true at all. You could see women in jeans everywhere in town. She closed the jeans and put on a belt. Grinning, she turned in the mirror. Since she had small, almost no breasts, she looked like a boy. Agnes grinned happily. Suddenly the door pushed open. Malcolm stood in the doorway and stared at his sister in shock.

"Agnes?" He whispered.

"I'm not Agnes!" She screamed. "Get out! Leave me alone!" Malcolm winced.

"Calm down, sister. Please." He walked up to her with his hands up.

"Go away!" Tears began to run down her cheeks.

"Agnes, calm down. Come on."

"Don't call me that!" She cried.

"Please calm down, Ang. Please." Malcolm pleaded. He hugged her tightly. She cried and pounded his chest weakly. "Why are you wearing my clothes?" Malcolm asked quietly as he recognized it.
