"I need to tell you something, Ms. Cherilee..."
The day was long and boring. it was at the end of the school year, and everypony was miserable due to the heat of the day. Diamond Tiara was anxious to have school end, only fifteen more minutes. She stared at her assignment, she just dumbly looked at the plus signs and subtraction symbols.
"Please, let the bell ring already!" Said Diamond's thoughts, with it's usual snotty tone. She Impatiently tapped her hoof on the ground, hearing the soft, click clack as it made contact with the hard floor. Diamond Tiara nearly went flying out of her desk as the bell rang.
"Okay my little ponies, get home safe and make sure you do your homework!" Said Cheerilee, with a happy demeanor like always. Diamond waited patiently as every filly and colt left the classroom. She had a hard feeling in her stomach, like she had eaten rocks for lunch. The heat of the air only made it worse, making it hard to breath properly.
"Diamond Tiara, this morning you said that you wanted to tell me something, what was it you wanted to say?" Cheerilee wore a happy grin, making Diamond feel a little better, but not so much so.
"Um, well, you see... it's about... my dad..." Diamond Tiara fiddled with her hooves, not daring to look at Cheerilee. An eternity seemed to pass before she finally looked up slightly, seeing that Cheerilee had pulled in for a hug. Diamond willingly hugged back, the embrace eased some of her nerves.
"Diamond Tiara, you, must listen to me right now. I know that something is wrong, you have to tell me what's wrong or else the problem will never get fixed." Cheerilee spoke softly and kindly, the way a mother would to her child. Hearing this voice wanted to make Diamond cry, for she has only heard her mother's voice a few times, and it sounded exactly like this one.
"I miss you mama..." Thought Diamond Tiara, she sniffled and wiped her nose. She worked up some nerve and looked Cherilee straight into her eyes, and Cheerilee looked right back.
"My dad, he did something...wrong...to me." She whispered that last part, but Cheerilee still knew partially of what she meant. She gently grabbed Diamond Tiara by the shoulders and gave her a serious look.
"Diamond Tiara, you must tell me right now, what exactly he did to you. This problem will never get solved if you choose to not tell me what happened." Cheerilee spoke sternly, but softly, that way as to not put pressure on the poor filly. Diamond had tears streaming down her face, her lip quivered. The temperature outside only made the situation more uncomfortable. Diamond quickly wiped her tears away and took a breath. Cheerilee embraced her again, and asked her one more time what happened.
"He...he touched me, Ms. Cheerilee... touched me somewhere not good..." Diamond Tiara whimpered, a heavily steady flow of fresh tears running down her face. Cheerilee continued in her slow steady voice, while she wiped gingerly at the tears.
"Okay, you have to tell me one more thing, Diamond. Where did he touch you? I won't be able to help you if you don't tell me." The pink filly pointed at the lower base of her flank, where the joint meets the cheek of her rump. Cherilee huffed, what kind of father touches their daughter? She found the very thought of it revolting.
"Diamond Tiara, I promise you, that he will never, ever, ever touch you again. And Celestia help me, if I ever see him even look at you. I Promise that he will regret it." Cheerilee said it with an intensity in her voice, making Diamond feel confident again.
"What about when I have to go ho-" Cheerilee cut her off.
"I'll take care of it, I'll ask Twilight Sparkle if I can send a letter to Celestia." Diamond smiled greatly. She was so thankful that this wonderful mare was her teacher. She was so thankful that Cheerilee -unlike other ponies- didn't think she was lying just to get attention. She was so thankful, that this mare was born.
"Thank you..." Whispered Diamond Tiara. She was crying tears of joy. The magnificent mare held the weeping filly. They sat there in the stuffy classroom and hugged. Cheerilee nuzzled the top of her head, while Diamond snuggled into the embrace.
"It's been so long.... so long since I've had a proper hug like this...." Thought Diamond Tiara. The last time she has ever had a meaningful hug was before her mom passed away in the hospital, and that was many years ago. Cheerilee was the one who broke the hug.
"Well, let's go get princess Twilight, we have a letter to send." Cheerilee looked down and smiled at the pink filly.
"We?" Whimpered Diamond. The teacher nodded, and Diamond Tiara's heart soared. They both walked out the classroom, noticing that the sun had sank noticeably. The sky was a warm orange along the horizon, whilst a pale pink outline topped the orange, and the center of the sky was a beautiful blue. They both continued onward towards The newest princess's house, Cheerilee feeling determined and gaining intensity with every hoof step.
"As Celestia as my witness, I'll make sure that fucker pays..." That was Cheerilee's final thought before she knocked on the door and gave Diamond Tiara a short hug. Cheerilee knocked loudly on the castle door, and a lavender alicorn appeared.
"Oh Ms. Cheerilee, it's so nice to see you aga... Is something wrong?" Twilight stopped in mid-sentence and looked at the snarling mare. She then looked at the whimpering pink filly with a tiara.
"Princess Twilight, I need to send a letter to Celestia, we have a very serious situation on our hands." Cheerilee then took Twilight into the other room. Diamond Tiara could hear them whispering and little gasps of shock coming from Twilight. Both of them emerged from the next room and Twilight smiled at Diamond.
"Don't worry Diamond Tiara, I'll call your dad to say that you stayed with Silver Spoon. You'll be staying here with me tonight..." Twilight called for spike and he came running down as fast as his chubby scaly feet can carry him.
"Spike, take a letter..."
Author's Note
This story is about how you should ALWAYS tell someone if you have been abused in any way, shape or form. If you don't get help, then the problem will never get solved. Make sure that you can always call someone for help, or personally ask someone you trust. I've never been abused, but I know people who have been, so I wrote this story to raise awareness about these kind of situations. 
[P.S:] If there was any confusion, this is when Diamond Tiara is a couple years older, but she is not a full grown mare. She's just a few grades older is all.
