Sterek HS AU

Chapter 5...

A/N: Hi. How are you today? Are you okay? Do you need someone to talk to? My DMs are always open. 

Abuse trigger.

At the end of the school day, Derek was placing all the books he didn't need in his locker and all the ones he did need for homework that night in his backpack, neatly, when he could feel two arms wrap around his waist and warm lips pressed against the skin on his neck.

"Hey my sexy baby boy," Stiles said softly against Der's neck. "Are... you ready... to go home... yet?" He asked placing a kiss to Derek's neck and jaw every few words.

"Yea, but I also have to pick up my little brother, Tristan, from preschool before we go to my house." Derek said tiredly and quietly, but he didn't make any attempt or advancement to move from his current position. Stiles pulled away reluctantly and turned to face away from his beloved Derek.

"Der-bear? What is wrong? Did I make you mad?" Derek asked worried and confused.

"What? No, of course you didn't. I just turned around so you could get on my back." Stiles said reassuringly. Derek snickered but stilled hopped on to the farmer's back, and allowed him to carry him out of the school to Derek's sleek black Camaro. Derek got off of Stiles' back and tossed his backpack in the backseat. Stiles turned to face Derek and held out his hand asking for the keys to drive.

"What? Oh. Oh no. Nope, nope, nope. I am the only one that drives this beauty. Sorry, babe." Derek said as he proceeded to walk to the driver's side and get into the expensive car. Stiles deflatedly got into the passenger seat.

"Ok, so there is a few things that you need to know about my brother. One, he gets easily emotionally attached because it has been just he and I for the past four years. Two, he has anger issues as well so he may stay something that he does not mean or just have little outbursts for no reason, but he is a great kid. Who knows maybe he will love you and never get mad at you, it takes a lot to make him mad anyways. Lastly, he does indeed know that I am his brother, I promise, but sometimes he calls me dad or daddy because I have basically raised him since put parents died. We did move in with our uncle Peter, but he is barely ever home because he works as a criminal investigator. While he was gone I looked after Tristan and I have since forever, and when he got old enough I explained to him that I was his older brother not his father, but when is really happy, angry, confused, or scared he does call me dad or daddy." Derek explained quickly before pulling into the parking lot to Tri's preschool.

"Okay babe," Stiles replied as they exited the car and went to the front desk to wait to sign Tristan out of preschool for the day. As they were waiting in line behind the other parents, Stiles' arm found a resting sanctuary around Derek's waist. 

"Thank you. You took that really well. Most would freak out, you are truly amazing." Derek said just as Tristan was leaving his teacher's classroom. Stiles acknowledged his statement and he noticed the look of pure happiness when he saw his little brother run towards them.

"Dad!" Tristan exclaimed as he ran full speed ahead at the couple. Derek squatted down to catch him, and Stiles just watched in utter amazement at his boyfriend.

"Hey Tristan, how was school? Did you have fun? Was Mrs. Ray being a twit to you again?", Derek asked assertively, but you could hear the care and love that he held for his little brother. His voice held responsibility. before heading back to his Camaro, Derek picked the youngest boy up and carried him.

"School was okay, I guess. All we ever do is watch the same movie everyday, have playtime, and take a nap. it wasn't horrible, but it wasn't exceptionally fun. Mrs. Ray got mad at me and Malichai again today. During movie time, he was telling me about something. He said that his mommy is mean to his daddy. She always throws glass things at him. He said that she always yells and calls him mean names. His sister tries to protect him from their mother, but he said that when she leaves; his mom hurts him too. He tell me that she leaves big blue and purple marks on him. He even showed me them. An- And he told me that she throws him and his sister all the time like she does their father. I told him that if he wanted to he could live with us, but he said his mommy wouldn't let him. I wanna help him though. We have been friends for seven mo-months now. why are his parents so mean? And so that's why Mrs. Ray was being mean. Bu- But we didn't listen to her when she told us to be quiet. Are you mad at me?" Tristan told his older brother, reiterating every detail the exact way that he remembered it being told to him. "Also, who is that?" He questioned, pointing towards Stiles of which he realized was there when he got halfway through his story.

"I hope Malichai is okay, and we will do whatever it takes to make sure he is, okay?" Derek promised as he formulated a plan to nail the mother and save the broken and scarred family. 

"Oh, I am Stiles, your brother's boyfriend," Stiles chirped in acknowledgement of Tristan's question.

"Stiles? Like clothing styles?" Tristan inquired, trying to get a better understanding of the name.

"Well, kind of, but it is spelt different," Stiles tried to explain even though he knew that it would be a while before Tristan learned anything about the spellings of words and how they differ.

"Oh, okay. Der-bear, can I sit with Stiles?" Tristan requested.

"Sure, if it is fine with him," Derek replied, casting a questioning glance to the mentioned.

"I am cool with it, let's go," Stiles said to Tristan as he climbed into the backseat, situating Tristan's booster seat beside him.

At his answer, Tristan's bright blue eyes lit up, and he flew into the backseat. After making sure that everyone was buckled up and ready to rumble, Derek started his trip to their house.
