-STILES' P.O.V.-

Today is the full moon and Derek told me to avoid Destiny at all costs. So here I am, in the boys locker room, hiding out.

"Stiles? Stiles... You there? I can smell you." I heard a whisper and backed into a dark corner. "Stiles!" Whoever it was hissed. "Stiles, please." Now it was a whimper... Destiny's whimper. "Stiles, I'm sorry for hurting you, it's the full moon... You know? I feel terrible. Just come out. I just want to talk. Please, Stiles. Please." She begged.

I was about to step out when I remembered Scott tried to trick me like this too. /She's not sorry, Stiles. Don't believe her. She's just trying to trick you./ My conscience murmured inside my brain.

I can't let her get inside my head. "Stiles, I know where you are. Come out from your corner by the lockers." I glanced around to see that I /was/ in a corner near the lockers. Great. "I'm getting sick of trying!" She screamed.

Just then I saw two light-amber-ish-gold eyes in front of me, oh my god oh my god! I'm going to die!

"Stiles, hun, I'm not going to hurt you. I can smell your unnecessary fear."

"It's pretty necessary when you've gone phsyco!"

"Shut up!" Destiny cried out and grabbed my neck. Bringing me into the dim light and pressing my body onto the wall. "Listen, fucker, I could still kill you. I could just rip out your throat right now!"

"Then do it!" I choked with a small laugh. This situation seemed too familiar.

"Don't push me!" She tightened her grip on my neck. I rolled my eyes and laughed again, even though I was terrified. /Do not test her again, Stiles. The full moon is today. You don't want to die, do you?/ My conscience told me.

"Fine." I said under my breath to myself but Destiny seemed confused and tilted her head to the side a bit,

"What?"

"I'm sorry. Let's go get lunch." I seriously shouldn't take her to the cafeteria around so many people, but how else am I supposed to make it up to her?!

"No thanks, I'm not hungry." She seemed calm, wait what?!

"You're not hungry?!"

She smirked devilishly and said, "not for normal food."

"Fine, lets go get you a rabbit!" I laughed uncomfortably, trying to lighten the mood but Destiny didn't seem too pleased. She shifted her hand so her wolf nails were sticking into the sides of my throat, then I slowly felt the skin break and a warm liquid seep down from my neck to my shoulders. "I was just kidding!" I cried out, "Stop, Destiny! You're hurting me!"

"I don't care!" She brang her mouth to my shoulder and stopped the trail of blood from continuing down my chest. Then she slowly lowered my body (hands still on my neck) so I was at normal height with my feet on the ground. Destiny licked up the trail of blood until she got to the actual wound, her tongue burned against my skin and she pressed herself against me.

"Destin-" she cut me off by thrusting violently against my hips. Even though it still hurt, I let out a moan and grabbed her waist. "Don't do this again," I hummed against her skin. "Why don't you use Derek-"

Destiny dragged her nail over the cut on my neck so it was deeper and gushed out a new, fresh round of blood. "I don't want Derek, he won't let me have blood." She licked my neck.

"I-I shouldn't either..." I inhaled deeply.

"But you are,"

"But I shouldn't," I repeated.

She made a "Mhm" sound and kept rocking against me, it was one quick movement when she jumped up and swung her legs around my waist as I held her up by her butt and turned, pressing /her/ against the wall. Destiny had her arms around my neck and there wasn't one part of our bodies where we weren't touching. She sucked from my neck as I dry humped her.

"C'mon Stiles," she moaned, "lets just do it."

"/Yesss/" I dragged out the 's' in a hiss and threw Destiny to the ground, I tried to climb over her but it was no use because she grabbed my shoulders and shoved me down, going back to licking up the blood. I took off her shirt and she ripped off mine, lightly touching her nails all over my chest and stomach.

"Take them off," she moaned and scratched the waist of my pants.

"Are you sure?"

She moaned and I took that as a yes, pulling off my pants and dragging hers right off her skin. Destiny massaged the tent my boxers made until I tore off her bra and touched her everywhere.

"Enough of this!" She screamed and took off her panties, ripping off my underwear. I held her hips, pushing her back and forth on me as Destiny made a new gash across my chest, bending down and licking from it while pulling my hair.

A few minutes later, I shifted my hands lower so I had more control and in the process, a tattoo was revealed on Destiny. Just under her belly button and over her left leg. It was a bold and pretty cursive, saying, "Am I More Than You Bargained For Yet?" I recognized the line from Fall Out Boy's "Sugar We're Going Down". Cute. And accurate.

Destiny's head shot up and everything paused for a moment as she thought. "I-is there a practice today?" She asked, still not looking at me, but at the locker room entry door straight in front of her.

"No," I caught my breath.

"Then who- whatever." Destiny looked straight into my eyes as she began rocking back and forth again, her eyes were that pretty werewolf amber. They flashed with need and... /hunger/. She licked up the wounds from my chest and neck and then kissed me with her blood-stained lips, leaving a trail of red across my bottom lip.

"Harder," she moaned, so I dug my fingers into her hip bones and pressed myself deeper, and repeated the up and down motion until Destiny started to scream, digging her nails into my shoulders.

"De-DESTINY?"

Oh my god please don't be Derek please don't be- "Destiny! S-Stiles? WHAT THE FUCK?!" Then I recognized my best friend's voice. Scott. Oh my.

"Get out, Scott." Destiny rolled her eyes.

"Stiles! It's the full moon, you know what's ha-"

"SCOTT!" Destiny barked, and by barked, I mean actually /barked/. Like a dog. "GET OUT!"

"No!" He yelled and pulled Destiny up by her underarms, she kicked and punched but he held her arms and plastered her to him, keeping her steady. I sat up and quickly put my shirt over my crotch, staring only at Destiny and her naked skin.

"STOP IT!" She growled and ripped off a chunk of his shirt.

"That's my favourite shirt!" He pouted.

Destiny rolled her eyes and just then someone else bursted through the doors screaming, "DESTINY! I felt your- oh my God. WHAT THE HELL!" I didn't even have to look over to know it was Derek.

-SCOTT'S P.O.V.-

I held Destiny tightly to me, keeping her from trying to escape my grip. She screamed and I tightened my hold on her arms, "stop moving." I whispered in her ear.

"Make me," she said back.

"I will later, at home..." I winked at her, Destiny leaned in closer to my face until Derek ran in. He picked up Stiles and whipped his body into the lockers, Stiles cried out in pain and Derek shot his gaze to Destiny and I, running up quickly and grabbing her from my arms. He nodded to me and dragged her out of the room while she was still naked. Interesting.

"S-Scott!" Stiles choked on his breath, "hel-help me..."

I rolled my eyes and flipped him off, walking straight out.

I was laying on my bed with my hand in my pants, watching a video on my phone when without warning, my door flew open. I freaked out but when I saw Destiny standing there naked it felt like my hand was glued to my- Never mind. She closed the door with a smirk, walking over to me and climbing over me. "Can I take you up on that offer now?" She smiled.

"Hell yeah," I breathed and, let me tell you, Destiny is the best I've had in a while. I guess the whole "full moon" thing has an effect on her.

But just before the moon was at its peak I stopped everything and held her in my arms, whispering calming things into her ear.

I shouldn't be doing this. Number one because she's my sister, well, ADOPTED sister. Two because she's sort of dating Derek... If he didnt break up with her already. And three because Stiles likes her. Actually I don't feel bad at all and really don't give a fuck, werewolf sex is great!
