Just saying in advance that this chapter is a little dark; even for me. So if blood and gore isn't your thing, I advise not to read this.

Otherwise, hope you enjoy the chapter!

"Coming in on a Saturday," Stiles says, his voice cold and emotionless. "Now that takes dedication."

I smirk as Stiles and I walk into Mr. Yukimura's classroom, finding him sitting at his desk. He looks up from his stack of papers as his face drains, knowing that something wasn't right. He stares at Stiles for a moment before he looks over at me, his eyes wide.

"What do you want," Mr. Yukimura chokes out. He sounded tense and nervous; I loved it.

Stiles raises his eyebrow. "I want to know where the tails are."

"What tails?" Mr. Yukimura asks, trying to play it off. I hear hear his heart race in his chest. Stiles looks back at me, knowing that he was lying as I nod, knowing the same thing as well.

I step forward as I reach onto his bookshelf, pulling off books one by one. "Did she hide them, hmm? Did she hide them somewhere she thought we wouldn't look?"

Mr. Yukimura shakes his head. "I don't know what you're talking about, but if you're talking about tails, I can direct you to the library-"

"You know exactly what we're talking about," Stiles snaps as he walks forward, heading towards his desk. "I know she has one left. The older the tail, the stronger the Oni, right?"

Mr. Yukimura shakes his head as Stiles dwindles his fingers on the desk. "I don't know-"

"Oh you'll talk," Stiles snaps, his eyes narrowing. Mr. Yukimura holds his ground before Stiles reaches onto the desk; picking up a text book. I watch with eyebrows raised as a fly comes out from underneath it; flying and going into Mr. Yukimura's mouth. He chokes as he clasps his hands around his throat, seeming to not be able to breathe.

"I don't think he'll talk like that," I say playfully, raising my eyebrow at Stiles.

Stiles smiles before he turns around, heading towards the door. "Trust me; he will soon enough."

I smirk as Mr. Yukimura stares up at me, his eyes wide with desperation. A part of me felt bad for him, but I soon pushed those feelings away. I give him a small wave before turning and following Stiles out of the room, the two of us heading down the hallway.

"What exactly do you want that tail for?" I ask, cocking my head to the side.

Stiles doesn't look at me. "I want it to have control over the Oni. They're my only threat at the moment and I need to eliminate that threat."

I nod my head. "So what are we going to do now?"

Stiles shakes his head. "Now we're going to pass the time."

I grin. "I like the sound of this."

-----

"Good grief," I groan as I hold my phone. "Scott won't stop calling me."

Stiles rolls his eyes. "I can fix that."

I watch as Stiles takes the phone from my hands, crushing it with one easy movement in his hand. My phone crumbles as little pieces of it fall to the ground, clattering. I gasp as he drops the phone on the ground, looking up and smiling at me.

"That was a brand new phone," I complain, staring at my now broken iPhone.

Stiles shrugs. "You wanted him to stop calling you, right?"

I nod my head. "Yeah-"

"Well problem solved," he grins before turning and stepping out of the jeep. We were standing outside of Stiles' house; for a reason unknown to me. I figured that maybe he just wanted to mess around with the Sheriff's head.

I stare at Stiles' house for a moment across the street before a truck pulls up in front of it, a man in a blue uniform getting out. I raise my eyebrow as Stiles stands next to me, watching the man walk up to the doorstep.

"Great. A mailman," I say, placing my hand on my hip.

Stiles is silent for a moment before he walks forward, his voice going darker. "This should be fun."

I raise my eyebrows for a moment before smirking, knowing that things were about to get interesting. I quickly catch up with Stiles as we walk up to the mail man, waiting for him to turn back around. He sets a box down on the doorstep before he turns around, gasping at the sight at the two of us.

"You scared me," he says, out of breath. He laughs for a moment before he stops, staring at the two of us. "Are you two feeling okay? You don't look good."

Stiles smiles. "Yeah, we're fine. Just haven't gotten any sleep lately."

The man nods, somewhat suspicious. "Well, I better get going-"

Stiles grabs the mans arm. "Can you come inside for a moment? I need to ask for your opinion on something."

The man cocks his head slightly. "I have a lot still to do-"

"It will only take a second," Stiles says, a bright smile on his face. If I wouldn't have known that he was lying, I would have almost believed him.

The mailman hesitates before finally nodding. "Okay."

Stiles smiles before turning and opening the door, allowing the mailman and I to walk inside. Stiles starts to walk up the stairs towards his room as the mailman follows after him. I close the door behind me, watching the man walk up the stairs. I start to follow after the two of them before I hear something in my head.

Grab a knife.

I furrow my eyebrows for a moment, this being the first time that has ever happened. However, I could tell that it was the nogitsune telling me this; so I understood. I watch the mailman and Stiles walk around the corner before I walk into the kitchen, seeing a large knife sitting in a holder.

I walk over and pull it out, looking at how shiny and sharp it was. I paused for a moment when I saw my reflection in the knife, wondering for a split second if this was really me. I soon shoved the thought away before I turn and walk up the stairs, hiding the knife behind my back.

I listen closely as I hear Stiles and the mailman in his room; talking about the color of the walls or something. I mentally groaned at that being his distraction; but hey, it worked.

I peek around the corner and see Stiles facing me, the mailman's back turned to me. Stiles glances at me for a moment, telling me to do it. I nod slowly before I slowly walk into the room, being as quiet as possible. Stiles watches as the mail man talks to him, not knowing that I was right behind him. I slowly raise the knife as I prepared to kill him, but that was before I heard the nogitsune in my head again.

Don't kill him. Not yet.

I silently curse the nogitsune before I turn and bring the knife down in the mail man's thigh, going almost all the way through. He screams as he falls onto one knee, staring at his now bleeding leg. Stiles smirks as I breathe heavily, filling with adrenaline. I've never felt so alive.

The mail man turns and looks at me with hurt eyes; knowing that we were going to kill him. I smirk at him before Stiles walks over to the door, reaching down and grabbing a wooden bat lying there. The mail man's eyes stay on me before Stiles brings the bat on his head, knocking him out cold.

Stiles gasps as the man falls to the ground, the knife still lodged into his leg. I strain my ears to faintly hear a heart beat; meaning that we haven't killed him just yet.

"I told you that we'd make a good team," Stiles says, laughing as he stared at the man on the ground. I laugh before I look down at my hands, seeing that they were covered in blood, along with my nails.

I frown. "Oh come on. I just had a manicure not too long ago."

Stiles rolls his eyes. "You're such a girl."

I stare at him. "Is that supposed to be an insult?"

Stiles rolls his eyes before he kneels beside the man, staring at him. He places his fingers on his neck, feeling for a pulse. He nods in appoval before I raise my eyebrow.

"Now what do we do with him?" I ask, placing my hand on my hip.

Stiles looks up at me. "Now it's time for the fun part."

"I thought that was the fun part," I say as Stiles walks out into the hall. I groan before I stare back at the man, seeing that his eyes were latched closed. I step forward before kicking him softly in the stomach; making sure he wasn't still awake. He doesn't stir before Stiles comes back into the room, now holding a chair.

"Go grab the duct tape," Stiles says as I look around the room, finding some sitting up on a shelf. I grab it before I turn back around, seeing that Stiles had already put the man in the chair. I walk back over to them and wrap the man's ankles and wrists to the chair; making sure to make it tight as can be.

After I do this, Stiles and I step back, staring at the man now strapped to the chair. "I feel like I'm missing something."

Stiles and I think for a moment before Stiles nods. "I know what it is."

I watch at Stiles tears off a piece of duct tape, walking forward and taping it to the man's mouth. I nod and smile as Stiles steps back again, admiring the good work we had just done.

"Not too bad of a job for a girl," Stiles says, placing his finger on his chin.

I narrow my eyes as I stare at him. "Again with the girl insults?"

Stiles laughs before he nods towards me. "Alright, now it's your turn."

I furrow my eyebrows. "I don't have the knife-"

"Not that," Stiles says, crossing his arms. "I mean, do that pain thing."

"What pain thing?" I say, not understanding.

Stiles groans. "That thing where you take away someone's pain. I would do it, but I can't."

"Well you're out of luck," I say. "I can't do it either."

Stiles nods. "Yes you can."

I raise my eyebrows. "No I can't-"

"You might be a kitsune like me, but you're different. I know you can do it," Stiles says, making me curious.

"What do you mean I'm different?" I ask, turning my whole body to face him.

Stiles sighs. "You're better than the average kitsune. You can do things that none of the others can do. You can control your powers better and you can do some things that werewolves can even do; like take pain away."

I nod my head. "I don't even know how to do it-"

"All you have to do is think about it," Stiles says reaching out and grabbing my hand. Goosebumps rise on my skin before he places my hand on the man's shoulder, letting go and talking me through it. "Think about all of the pain you just caused him. Focus on that and breathe."

I slowly close my eyes as I focus, only hearing the mans faint heartbeat in my ears. A couple of seconds go by as I try harder, it still not working. I groan before I tighten my grip on the man's shoulder, feeling his pulse through his shirt.

"Relax," Stiles says, his voice soft. I feel his breathe on the back of my neck as he leans into my ear, whispering. "You can do this. I know you can do this."

I take one big breath before I concentrate harder, this time suceeding. I gasp when I feel an aching sensation run through my arm, causing my eyes to flash open. I look down and see that my veins were a dark black; flowing up all the way through my arm. I smile as the pain gets stronger, but it felt so good.

"That's enough," Stiles says before I let go, gasping. I grin as I stare at my hand for a moment, still trying to figure out how I managed to do that. Stiles smiles at me before he steps closer to me, staring at my face. "Now it's my turn."

I watch as he places his hand on my cheek, all of the pain that I had just taken flowing out of me. Stiles' eyes roll back into his head as his veins turn black, moaning with pleasure. I couldn't decide if I liked the pain more of if it felt better to not have it; but either way, it was satisfying.

Stiles suddenly lets go as he gasps, his breathing shaky. My eyes are wide before he slowly looks back up at me, a smile stretching across his lips. I smile at him for a moment before I hear the man in the chair stir; finally waking up.

I turn and look at him, seeing his eyes wide with fear. He scans the two of us before looking down at his leg, tears forming in his eyes. Stiles gives me a look before I hear that same voice in my head as before.

Kill him now.

I nod before I reach down, yanking the knife out of the man's leg. He hollers from behind the duct tape over his mouth as blood stains the floor; along with my hands. I see Stiles smirk out of the corner of my eye as I raise the knife again, angling it across his throat. The man shakes his head as he tries to get out of the chair; but it was no use.

I feel no remorse as I slice the knife across his throat, blood splattering up onto my face. I watch as the man lets out one last breath before his head falls, dead. I listen to his heart slow to a stop as Stiles smirks, staring at me like a proud mother who's son just scored the winning goal.

I drop the knife to the floor before I look down at my shirt, groaning. "He got blood all over my favorite shirt."

I sigh before Stiles walks around the chair, lifting my head. I watch with wide eyes as he brings his finger to my chin, wiping off a splatter of blood. My heart races in my chest as my eyes stare at his lips, Stiles staring into my eyes. Before I know it, Stiles is slamming his lips to my own; his hands trailing my face.

I moan softly before the kiss goes deeper; more than the kiss Stiles and I had last time. My skin feels like it's on fire as Stiles tugs on my shirt, helping me lift it up above my head. His lips peck at my neck as I help him remove his shirt, tossing it to the side as it lands in a puddle of blood.

Stiles is soon lowering me onto his bed, not daring to let our lips part.

-----

Okay so like I said, this was a little dark AND kinky. And yes, Stiles and Sarah DO THE THING. THEY DO THE THINGY THING. I personally couldn't write about it because, well, I'm 15 soo...

Anyways, just so we're clear, there isn't a video camera in Stiles' room like there was on the show. If there was, I'm pretty sure Stiles would be grounded after all of this...
