Much to her displeasure, Elsa approached her classroom again. It's time for her students to face the consequences of their actions, but she hated herself for wasting one precious hour of her life. Instead of babysitting the teens while grading tests, she could be at home, doing the same thing. Does that make a difference? It does.

As she walked down the hallway, the young teacher spotted a raven-haired girl sitting at the foot of the lockers. She has a book settled on her thighs, and her hands shook slightly as she turned the pages. She wondered if they would feel gentle or rough against her bare skin. Staring at her for a little longer as she went, Elsa noticed what she's doing: the student is reading.

She stopped in from of the raven-haired girl, and a small cough left her mouth. Her attention turning towards the teacher, Cassandra closed her book with a swift motion, like she was hiding something. A faint blush appeared on her pale cheeks, and she almost threw the book into her bag.

"You shouldn't be sitting on the cold floor." The teacher's soft voice reached the student's ears, and she stood up, hovering above the blonde. Ms. Andersen didn't pay too much mind to their height difference, but now, being this close to her, it feels intimidating. "Where's Hans?" Elsa asked.

Cassandra shrugged and answered her teacher's question. "I don't know. Maybe he left."

Sighing, Elsa began walking to the door of her classroom with Cassandra by her side. I should've known he won't stay. It's all because his father is the headmaster. She felt slightly surprised and pleased when the younger girl opened the door for her and politely let her inside first. "Thank you." She murmured under her breath, her voice so quiet that Cassandra could barely hear her.

"So..." The raven-haired girl closed the door behind her and followed her teacher to her desk. "What happens now?"

"You don't know?" Elsa asked, her eyes widened, and her expression surprised.

"I've never been in detention, so I have no idea about what I'm supposed to do." Cass nervously settled her bag on a nearby desk and lazily sat down in a chair. "Based on what I did today, you might think I spent all my school days beating up people who bullied me." She bit her lower lip and swallowed so hard that Elsa could hear it. "But I did not."

That made Elsa think a little. Cassandra is rather young, and despite that, she didn't seem so innocent. The way her eyes searched for the teacher's gaze with a burning fire in them, it made Elsa's knees shake slightly under her desk.

Those piercing orbs seemed to be undressing her, ripping the buttons on her blouse apart with raging desire. And Elsa liked that for some reason. She wanted the young student to press those luscious lips against hers, and travel them down on her naked body, to take her to the heavens and back until she's begging her to stop.

She imagined the same eyes looking up at her from between her legs, a sly smirk on the student's face as Elsa's world fell apart thanks to her mouth. Her mind seemed to be focusing on the things Cassandra could show her until she quickly pushed her fantasies away.

Elsa wondered why she had these thoughts in the first place. Cass is her student, who happens to be almost a decade younger than her. There's no way anyone could make her feel like that in such a short time. But Cassandra is just a kid, and while Elsa is supposed to be a responsible adult. This should remain a fantasy. But she still wished to see those tight muscles at work.

The blonde sighed, feeling an unfamiliar warmth in her heart. The teenage girl seemed tough on the outside, and Elsa thought she might be similar inside. Never judge a book by its cover. Maybe she's a softie. "If you have any homework, you can do it now. I'll be grading tests."

And with a nod, Cassandra went to work. It's only her second day at Arendelle High School, and she's already in trouble. Her mother definitely won't approve of that, but she'll deal with her later.

What is more important is that she has barely any homework for tomorrow, and within just a few minutes, she finished them all. With a sigh, the grey-eyed teen put her things away and took out a book from her bag, the one she was reading earlier. If she doesn't see the cover or the title, it's all good.

Elsa continued to grade the students' tests until she stumbled upon Cassandra's, smiling to herself as once again, she admired the student's beautiful handwriting. Her eyes roamed over the piece of paper, surprised by the answers — all of them are a hundred percent correct.

Looking up from her work, Ms. Andersen caught a glimpse of the book in Cassandra's hands, not quite enough to see the title nor its cover. Her voice failing her for a quick moment, she opened her mouth to speak, but no sound left her pink lips. Regaining her composure, she cleared her throat, earning Cass's attention again.

"Your test...the one that you wrote yesterday...it's the most correct, your answers are absolutely perfect. How?"

Calmly placing her book on the desk, Cassandra smiled at her teacher, and Elsa immediately thought she's going to faint for an unknown reason. "I've read that book before, multiple times, actually, so I know it by heart by now. It's a deep, meaningful one."

"I agree with you. However, most students don't really like it." Ms. Andersen seemed somewhat disappointed, and Cass could see why.

"Because they are busy doing useless things. They don't understand the beauty of reading."

Is it hot in here? Elsa thought to herself as she felt the temperature rise in the classroom. What's happening to me? "Perhaps you are right. I don't really know much about what the youth does these days."

"You must be kidding me," Cassandra said without thinking, then she blushed slightly at her awkwardness. "I mean, with all due respect, you look young, so you can't be much older than me."

"That's very kind of you, Cassandra. But let's just not talk about my age. Do you like literature?"

"I love reading, but the subject..." The student paused for a moment, thinking about the most appropriate way to answer. "...no, I hate it with my whole being. I think literature should be about books and poems, not learning useless information about dead guys."

Sighing, Elsa gently tapped on the desk under her fingers. Each sentence by Cassandra made her seem more mature and...attractive. But Ms. Andersen quickly perished the thought. "I can't say I disagree, because that would be a lie, but as a teacher, I don't think I can voice my opinion about this topic. What kind of books do you read?"

"Almost everything. I like books that made me think or react emotionally—a little bit of everything."

"I like that too," Elsa said softly, her heart hammering against her chest. She's unexpectedly amazed by her student, and somehow, she wished she could give her detention every day. "I feel bad for not asking, but why did Hans bully you?"

"He didn't like my looks and my accent. He said I'm too muscular and I look like a man, my accent makes me sound like a peasant, and my eyes are frightening. He basically hates everything about me, which I don't understand since we only met a day ago."

"And that's the reason you attacked him?" Elsa asked, curiosity in her velvet voice.

"No." She paused for a moment. "I don't care about what he or anyone else thinks of me. But when he started saying nasty things about my mother, I couldn't just stand there and listen to his insults."

"I understand you were angry, and you had your reasons. But violence doesn't solve anything."

Cassandra sighed and looked at the lesbian romance novel in front of her. "I know, Ms. Andersen. I know..."

"Hi, mom!" Cassandra panted as she pressed a small, quick kiss against her mother's cheek. She ran inside the house just a few moments ago, the anticipation building in her chest.

"Hello, sweetie! How was your day?" Zara asked and continued to stir their dinner.

"Can't tell now!" The young girl rushed upstairs and shut the door behind herself as soon as she reached her bedroom. She threw her bag in the corner and jumped on the bed, her phone immediately ending up in her hands. Her first thing to do was to text her old friend whom she met during her exchange studentship in China.

Cass: Hi, Mulan! You won't believe what happened!

She bit her lip as she awaited her friend's reply, impatiently opening and closing her Messenger application until she got a notification.

Mulan: Heyy! What's up?

Cass: I spent one hour with the most beautiful woman in the world.

Mulan: Wow! Tell me more about her! :D

Cass: She's my literature teacher.

Mulan: Ancestors... Please tell me you didn't do anything with her.

Cass: Nothing yet.

Mulan: And that's exactly what I'm afraid of. Look, if you want her, go for it. But be careful, she has more to lose than you do. Just don't get in trouble, okay?

Cass: No promises ;P

The next two weeks went by quickly. Cassandra seemed to a quiet but cooperative student, who had more interest in her books than any subjects, yet she always managed to get good grades. Somehow, Elsa started to become quite fond of her.

After classes, sometimes she asked the student about what she's reading, and to her surprise, she never seemed to get an honest answer. She wondered if Cassandra is truly hiding something.

Speaking of Cass, she's just about to go home with Anna by her side. Together, they are walking along the hallways, anticipated to go through the entrance to be freed from their prison.

"Ugh! I can't believe we have a Math test tomorrow! Mr. Weselton is insane!" The redhead complained as Cassandra pushed the door open, allowing both of them to go through. "And, of course, I don't understand a thing!"

Cassandra giggled at the other student. Maybe she's not a genius herself, but if she can help her, she definitely will. "Do you want to study with me? I could explain a few things to you."

"Really? You would do that? I mean, yeah, thank you! Let's go to my place!"

"Alright." They walked to Cassandra's car, and she drove them to Anna's home.

At first, the redhead was afraid of Cass judging her. She's far from rich, while the taller girl could bathe in money, and that still wouldn't affect her family's financial situation. But Cassandra showed no sign of rudeness and even complimented the small home that's just enough for two people, Anna, and her unknown sister, who happens to be still at work.

That would be a lie if Cass said she has no desire to meet the older Andersen girl. But for now, they have more important things to do.

Anna led the new student inside her room, and they both sat down on the bed with a Math book in each girl's hand. As time passed, Cassandra seemed to be quite a good teacher: she was patient, and if Anna asked, she replied as best as she could.

At some point, Anna changed the topic. "So...how do you like Arendelle High?"

"It's not bad. I mean, Hans is an asshole, but most of the students are nice. And the teachers...sure, Mr. Weselton is an idiot, but Ms. Andersen is the hottest babe in the world. Oh boy, if that means being alone with her, she could put me in detention anytime."

Anna almost choked on her own breath, and a deep blush colored her skin from her chest to the tip of her ears. I never thought she's into girls! I mean, it's kinda obvious, but since she never mentioned it. But most importantly, she doesn't know Elsa is my sister! "Yeah, um, she's really nice, and I guess s-she's one of our best teachers!"

"I can see that." The taller girl sighed and leaned against the wall, resting her back. "You can't even imagine the things I would do just to touch her. I wish I could make her wear shorter skirts during classes because those long legs are breathtaking."

They were rudely interrupted as someone knocked on the redhead's door. The girls exchanged glances, and Anna almost fainted in her embarrassment.

"C-come in," Anna said, her voice cracking.

"Hey, Anna!" Cassandra's eyes widened as she heard the soft, familiar voice that caressed her ears like the most delicate fabric. Her heart pounded in its place as the door opened, revealing a certain, beautiful blonde woman with icy blue eyes, pale skin, and a body worth dying for. "I just came home, and I was wondering if you'd li-" The woman gasped in surprise at the sight of the young, attractive student. She definitely wasn't expecting that. What is she doing here? "Cassandra?"

A/N: BUSTED

I can't wait to write about Elsa and Cassandra's reaction xD

Poor Cass. She probably just wants to die right now.

I kinda want this story to have a lot of teasing and juicy fantasizing before anything serious happens, so be prepared for that *wink wonk*
