The True Mates (Derek Hale Fanfic- Teen Wolf)

Let's Fight...

Sam's P.O.V.

I walk up to see a curly haired boy sitting on the couch. "Umm... Who are you?" I asked nervously.

"Oh I'm Isaac, Derek's beta... Who are you?" He asked look at me with a smirk.

"I'm Sam, Derek's... girlfriend. So, what are you doing here anyways?" I asked sitting next to him.

"Well Derek told me to watch you while he's gone." He said smiling. "Where'd he go?" I asked curiously.

"Help Scott with something." He says. "Oh okay, wanna do something?" I asked bored out of my mind.

"Like?" He asked sitting up from the couch. "Training." I say smirking.

"I don't think Derek wi-" I cut him off my flipping him over. "Who cares what Derek thinks he's not here right?" I say walking up stairs.

"Ya... Where you going?" He asked getting up. "To change, Derek said Cora had clothes in her room she had when she stayed here." I say going all the way up and going to her room.

"GET READY!" I shout for him to hear me. I find Nike sports bra and Nike leggings then put it on.

Isaac's P.O.V. (didn't see that coming!)

I look around for Derek's clothes but can't find any. I don't live here anymore cause I live with Scott so I have no clothes.

I hear foot steps and look up to see Sam with a sports bra... Woah. "Where's your clothes?" She asks looking at me.

"I don't live here anymore all my clothes are at Scott's." I say trying not to stare.

"Just take off your shirt so you don't get it all sweaty." She say plopping down on the couch smirking.

"Derek wouldn't li-" she cut me off... Again. "Derek's not here. Plus I'm too old for you." She says looking at her nails.

Sam's P.O.V.

I feel like Isaac is scared of Derek but who cares he wouldn't hurt Isaac anyways.

I look up to see Isaac shirtless in the middle of the room and smirk.

"Let's fight..." I say getting up and kicking him in the leg. He falls face first... Ouch. "Oh my gosh Isaac, you okay?" I say crouching down to check on him.

As I go to touch him he grabs my leg and makes me trip on my butt. We both get up and look at each other.

"I won't go easy on you just saying so watch your back." I say putting my leg in the air to kick him only for him to grab it and twist me over.

"Wow... Curly has some moves." I say laughing and getting up.

He laughs "Don't call me that ever again." "What you gonna do if I do?" I ask crossing my arms.

"You'll see if you do." He says smirking and turning around.

"Curly..." I say as he turns back around and runs after me.

"Don't call me that." He says running after me and chases me. He then puts me on the bed and starts to... Tickle me.

"Say sorry and I'll stop." He says tickling me on my stomach.

"Never!" I finally get out while laughing. "Say sorry or I won't stop!" He says laughing too.

I smirk as I see the door slide open "You gonna wanna stop now." I laugh smirking at him.

"And wh-" Isaac gets cut off by Derek coming in.

"Isaac! What the hell are you doing?" He asked angrily.

"I uh uhm... I'm gonna go." He says picking up his shirt and leaving.

I laugh as he exits "That's was fun." "What was?" Derek asked looking at me with anger plus sadness... What's up with him?
