Stiles walks into the loft having been sent a text about an emergency.

"Derek?"

After taking a few steps in the door is slammed shut and Stiles quickly tries to reopen it to no avail. He can't get it open.

"Fuck that's not good. Derek you in here?"

"Stiles?" Derek groans and Stiles runs toward his voice only to see him chain to his bed mostly nude.

He couldn't help but scan Derek's form.

"What happen?"

"Some woman. I never seen before. Mage of some sort. She put a spell on me a chained me up. She wrote the details on the paper over there, stole my phone and shot off a text."

"A text I got and now I'm locked in this loft. I'm a bit concerned about what is on that paper."

Derek looked a fair bit worried as well but Stiles grabs it and starts reading it.

Stiles, Stiles I warned you I would force your hand. I told you to come clean to your dear Alpha. Now you have a choice. Wait till my lust spell fully takes hold of him and the chains weaken enough for him to break free and bed you. Reveal one of the secrets you hold which is that you are a spark by purging my spell from him. Or third tell him the truth about your feelings for him and break the spell that way. You have two hours.
Your teacher,
Paya

"This is my fault. I'm sorry Derek this is all my fault."

"What's wrong?"

"Don't worry I can fix this. She knew I'd never let the spell activate. That I'm not that cruel. My protective instinct for the pack being more important the my personal safety."

First Stiles looks Derek right in the eye and ignites the letter. Burning it to ash before walking up to the stunned wolf.

"S...stiles what..." He pauses as the spell ramps up and he tugs at his chains and his eyes start to glow.

"Lust spell. Either I expose one of my secrets to break the spell or you eventually break those chains and attack the first warm body you find. Which in this case is me. I wont let you go through that trauma. So I will break the spell using the least risky method."
Stiles places his hands on Derek's bare chest, trying not to think about the feel of his skin.
Using all his learned skill he shatters the spell and stumbles back as despite a several months, almost year of practice, doing big things like breaking that high of level spell drains him. But he forces himself upright and uses his magic to free Derek from the chains before collapsing only to be caught by Derek.

When he comes to he sees Derek standing over him worriedly. Feeling the soft mattress under him.

"Relax Sourwolf, I'm fine. Just that was very high level spell she used on you so it took most of my energy to break."

"So your a mage?"

"I'm a spark. I awakened my dormant magic a little over a year ago and was taken in by a teacher. The Mage that did this. We became really good friends but she hated that I was hiding what I was from my pack. That I should be proud to be a spark. That they were the rarest, strongest and most sought magic users that packs would love to have as an emissary. She didn't really understand why I wanted to keep it secret. Though I explained it. She is a bit different she doesn't understand the reason for hiding certain types of secrets. So she did this to force me to reveal that I was a spark."

"You said revealing yourself was the least risky option to break the spell what was the other."

"Not important."

"Well why did you keep it from the pack?"

"Because I didn't want the pack to only keep me around because I have magic. I already feel like I'm not wanted in this pack. That I'm just the token human. Do you know how much I would hate it if the only reason that changes is because I'm magic."

Derek recoils as if he had been struck.

"Stiles...We love having you around. Magic or no magic. Your pack and a value member at that."

"Oh really could have fooled me. I'm mostly ignored, mocked for being weaker, treated like I'm going to shatter, and treated as useless a burden and that I just get in the way. You yourself ignore me unless I irritate you enough to threaten me. When I do save one of you, tend to your wounds or cook for the pack I don't even get so much as a thank you."

Derek felt sick, has this pack really slipped so far. Has he really failed that bad at being an Alpha?
With out thought he pulls Stiles into a hug.

"You are not a burden, You're not weak, I never thought of you as that. You're smart, caring, protective, resourceful and funny. I apologize for my part in making you feel like you don't belong. Truthfully this pack would be lost without you. Never feel like you have to hide anything from me. Even if you don't want the whole pack knowing something at least...At least tell me. I want you to be able to trust me and confide in me."

Stiles curls into Derek soaking in the warmth of this rare affection. He wished he could be affectionate with Derek. That Derek would be able to return his feeling for him. It was then he noticed...Derek was stile almost completely nude. Only Boxer kept curtain parts from showing. Stiles turns bright red and his mind supplied for to many flashes of a sexual Derek.
He hears Derek give a low purr like growl and his hold tightens.

"Stiles..."

"Y...yes?"

"Are you actually attracted to me."

Stiles tenses and he could feel panic well in his gut.

"I'm sorry, I mean I try to hide it. Its just your sort of only in Boxers and I was close to you and loving you doesn't help keep the lust part away. I know you have no feeling for me..." Stiles long panic babble was stopped short by Derek's lips pressing against his own.

Stiles melts into the the kiss on instinct as his brain fried at the feeling of Derek kissing him. Derek swipes his tongue along his bottom lip. Asking for entrance which Stiles happily gave. After Derek pulls away Stile stares at him in shocked silence.
Derek gives a smirk.

"So you love me?"

Stiles turns bright red but nods awkwardly.

"Good I have wanted to be with you a while now but always thought you were straight."

"Bi."

"So will you go out with me".

Stiles grins happily at that man and kisses him soundly.

"God yes."
