Teen Wolf one shots (mostly angst)

26- Derek+Stiles👶🏻

•Title: "Slip Ups"

•Requester: nobody lmao

•Warnings: Okay so this has age regression in it. I'll explain it below. Also, violence.

•Inspiration: I recently came across Sterek age regression fics and I'm in love.

•Type: age regression, fluff.

A/N: Okay so age regression is a coping mechanism, nothing sexual. a little is someone whose mind regresses to a younger age in order to cope. In this mental state, or little space, the individual is unable to complete tasks they normally could. This sometimes makes them seek out someone to look after them, or a caregiver. Outside of little space, the individual might be in a romantic relationship with the caregiver, other times it's strictly platonic.

The pack in this includes: Aiden, Allison, Derek, Ethan, Isaac, Jackson, Lydia, Peter, Scott, and Stiles. Derek is the alpha in this. Also, there may be hints of Scisaac, Lydia+Aiden, and Ethan+Jackson as well. Oh, also, Derek is only two years older than Stiles in this. Stiles is 18, Derek is 20. He's just more mature

_________________

Stiles Stilinski is your average high school senior. He has ADD, anxiety, and PTSD. He is one of the only two humans in the pack, and the other is a trained hunter. Stiles only has one thing that makes him stand out. He is a little. Stiles is in a relationship with the alpha, Derek Hale. When the pack found out they were together, they were shocked. Derek never really shows his emotions. Stiles and Derek's dynamic was always full of sarcasm, threats, and insults. Even with their supernatural abilities, none of them could realize that it was all fake, that the two were actually flirting. The pack knows that Stiles is a little and that Derek is his caregiver. They never once have shown judgement, not even Jackson. Stiles still doesn't want to be little around them, but sometimes he slips up.

The pack is sitting around Derek's living room. They were over for a "meeting" but since there is no enemy at the moment, they're just watching movies. On the couch, Isaac is sitting next to Scott, who has his arm around him. Next to Scott, Allison sits. On the chair to the right of the couch, Derek sits in one of his chairs. To the left of the couch, Peter is in the other chair. Laying on the floor in front of Peter is where Stiles is. Next to him is Lydia, followed by Aiden, her head on his chest. Next to Aiden is Ethan, who has Jackson to his right. Jackson is holding Ethan's hand.

Stiles can feel his head grow lighter. His mind is no longer on the movie as he looks around at everyone. he rolls around as he tries to get comfortable, not being successful. He tries to focus on something, anything, to keep from slipping, but knows it's inevitable. He hadn't slipped in a few days, so he knew he needed this. Now fully slipped, Stiles shakily stands up, struggling to do so in his toddler state of mind. He stumbles across the room, walking in between the couch and those who are laying on the floor. Derek had been watching Stiles, so he was well aware that Stiles had slipped. As he sees the little approach him, Derek opens up his arms, allowing Stiles to sit on his lap, nuzzling his face into the alpha's chest.

"Hi," Stiles whispers.

"Hi, Bub," Derek says, "you okay?"

"Ya. I just wanted der-der," Stiles says in a quiet voice, causing everyone to look over in shock.

"Did he just call you Der-der?" Isaac asks with a bright smile, causing Derek to sigh.

"Oh my god that is priceless," Jackson adds.

"Yes he did, and if any of you think about calling me it, I will rip your throat out," Derek says.

"With his teef," Stiles adds, not moving his face from Derek's chest.
