This is my first ever fan fiction so I hope you like! I have been a fan of this pairing for so many years and have read a lot of the stories on this site. I have written this as a one shot but it can easily continue, I'm sure I can be persuaded!

I do not own any of the characters or the show of 'Life With Derek'...it wouldn't have ended the way it did otherwise :p ENJOY!

"I can't believe you would do this! I mean I know you have a thing for invading my personal belongings Derek but this is a joke! The fact that you even look at that filth is in its own way, the foulest and most disgusting thing on the planet but –"

"How is it disgusting?" he snapped, interrupting my rant.

He was now standing in front of me at the bottom of the stairs, with a dangerous look in those familiar brown eyes. Even in my current state of mind, I couldn't help noticing that the working out over the summer had caused his t-shirt sleeves to strain under the size of his new biceps as he folded his arms across his chest. I think you'd have to be blind not to appreciate it. Realising that I had yet to say anything, I looked at Derek with the best look of bewilderment that I could manage in my furious but yet strangely distracted state of mind.

"Are you kidding me? Did you seriously just ask me to explain why porn is disgusting?"

"Yeah Case I did. Please indulge me." He whispered, as he took a very intimidating step towards me.

"Ok." I smirked, and mirrored his cocky, yet intimidating stance by taking a step forward off the step and folding my arms across my chest. He wasn't going to know what hit him.

"Pornography is just another excuse for men to completely humiliate women. It objectifies them and just makes them another tool for men to control. Not to mention, it gives men an unhealthy view of what a woman should look like in bed and can create a huge amount of pressure on a woman to think that she's not sexy enough just because she doesn't have huge boobs, tanned skin and a body with less that 3% body fat…"

"Wow, is that seriously the best you can come up with? Casey, did it ever occur to you that these women, lets call them porn stars shall we, actually chose the life that they're living right now and maybe enjoy it? Nobody forced them to do it, if that's what makes them happy, then I say that's fine. I'm not going to judge them just because of their job and as for it objectifying and humiliating them, I've been out with plenty of girls who watch it and find it quite liberating to express themselves like that sexually because it gives them confidence and ideas to spice it up in bed."

"You'd better be careful Derek; you're starting to sound smart. Please don't hurt yourself." He raised his left eyebrow in annoyance before he continued.

"I do agree that it may cause insecurity in women to think that they have to look like what you described in order to even be on the margin of sexy, but let me assure you, from a male perspective, we would much prefer someone real and right in front of us than stare at a computer screen for hours at a time."

"Oh hours Der? You sure you're not exaggerating a little bit?" I pouted, mocking him with my puppy dog eyes.

If I didn't know better, I could swear I was slightly flirting with him. I knew it was below the belt but by this point we were both dangerously close, noses nearly touching and as I looked up at him I could feel the fire in his eyes as I questioned his manly pride. I was prepared for him to growl something explicit at me and head upstairs but as always, being Derek he couldn't resist catching me off guard. Just when I thought I'd won, he tangled one of his strong hands in my hair and yanked me closer to him so we were barely a breath apart, my hands now pressed onto his chest with no room to move. I'd never been so conscience of his body against mine before…when we were wrestling for the remote we had an agenda, a goal. Now was different, I could feel his toned chest through his thin excuse for a t-shirt and found myself unable to shift my gaze from his mouth, that was now so close to mine. I was ashamed to hear a moan escape my lips as he tugged harder to get me to make eye contact.

"I think you and I both know I'm not. I know for a fact you were in your room the last time Sally and I had sex and I'm pretty sure you were the one that shouted through the wall and I quote 'for god sake Derek, stop taking so long and just finish already'." He whispered huskily.

Damnit…I did say that and looking into those eyes and seeing that annoying smirk on his face, I knew he thought he'd won, but I wasn't backing down just yet. He still had a lot to answer for, only this time I thought I'd try a new tactic. Rather than push him away and start yelling, I figured I'd beat him at his own game, so I lowered my voice to his intimidating level.

"That doesn't change the fact that you changed the wallpaper of my computer to that disgusting pornographic image and signing me up to all of those sites so now my inbox is full of X rated websites that would make even Ralph blush. Was that really necessary?"

"Oh Case, don't you get it? If you can hear me having sex, I can hear you and I'm telling you now, Truman obviously is not hitting the mark because it's very obvious that you have a set up pipes on you by the way you scream at me but…all I ever hear with you guys is him and trust me that's more disturbing."

"The reason that I'm quiet is because I know family are in the house. Perhaps you should show the same consideration."

In anger and embarrassment I tried to push myself away from him, which only served in getting my hair pulled again. I didn't want to admit it to myself, but I was starting to like it.

"When it's done right, you're not able to think of anything else other than what's in the moment. If Truman was truly causing you immense pleasure then you wouldn't be able to contain yourself, just like what I do to Sally."

"Oh please. You think you're Gods gift?"

"Hardly. I wouldn't be much fun now would I? Listen, it started off as a prank but use it your advantage. Find out what makes you tick, or better yet if you find yourself unsatisfied by Truman, which I know you are, then use it as a means to tip you over the edge…so to speak."

I couldn't believe I was having this conversation with him, Derek, my step-brother!

"Who are you to say when I'm sexually satisfied or not? You have no idea, what I'm like in bed."

"I know I don't but I bet that I would make you scream my name with no care in the world if I wanted to."

"Prove it."

Our lips crashed together in a heat of passion that neither of us had seen coming, as my heart leapt in my chest. Feeling his lips on mine was enough for me to want to rip off my clothes there and then. As I wove my arms around his neck, he saw the opportunity to snake his arm around my waist, pushing me further against him. He was right, in that moment I was aware of nothing but his lips on mine, the way his hands seemed to caress and find every inch of me, and the way his firm body felt as he pressed me against him. Everywhere he touched left fire in its wake, making me shiver in anticipation, want and need. I never knew a kiss could be like this, so urgent and yet so tender at the same time.

It was at that moment that Derek picked me up and by instinct I wrapped my legs around his waist, with him using my gasp of surprise to let his tongue seek entrance into my mouth. I'd never approved of Derek smoking, a secret he had made me keep to the grave, but the taste was strangely erotic on the tongue and only served in adding fuel to the fire. I was unable to hold back any longer as I found myself grinding against him and with an instant reaction of him moaning into the kiss. I could feel his erection through his jeans which only served in heightening my sexual desire, knowing that I was making him feel good.

The more I ground against him, the more Derek seemed to fight with his self control. I could feel it slipping as his hands moved from around my waist and my hair to my jeans covered ass, where he used his strong hands to push me harder against him and using it as momentum. I was beginning to lose control as my moans became more frequent and louder. As much as I tried to stay quiet, just to prove my point, I couldn't keep myself from vocalizing my satisfaction. I felt electricity going through every fibre of my body as I tried to retain any self control I had left. Sensing I was close, Derek slammed us round and pinned me up against the front door, breaking the kiss to turn attention to my neck while continuing to grind against me. My hand tangled in

his hair as I pushed him further into my neck, while he pinned my other hand against the door.

"Oh my god Derek, don't stop, please."

I was expecting him to give me his famous smirk and gloat but instead he kissed me one last time and looked at me as if I was the only thing that mattered in the entire world.

"Your wish is my command."

He resumed kissing my neck, until he tightened his grip on me and bit me hard, in the juncture where my neck and shoulder met. I don't know why, but this was the most erotic, animalistic and pleasurable act I had ever experienced in my life, and served in tipping me over the edge. As soon as his teeth made contact with my skin, electricity seemed to flood every nerve ending in my body as I started to spasm and experienced the best orgasm I had ever had... and of course screaming Derek's name so loudly…I'm surprised that China didn't hear me. I was in such a state of euphoria by what he had let me experience…and that was just grinding!

"Told you."

*DING DONG*

Shit

I know, I ended it on a cliffhanger! Like I said before I'll be more than happy to continue if people like it enough :) x
