A/N This story is set early new moon, just after Jacob's first shift. These characters are not mine, but most of the story line is.

I hope you enjoy this little variation to the typical story.

Is it wrong when you become your best friend's booty call? Is it worse when you get knocked up by said best friend? And is it just down right awful when said best friend and baby daddy is in love with your sister? I thought so. M rated for a reason.

Chapter One- That Day

Renesmee's POV

I can remember exactly how it started and the first time it happened. He just showed up at my door, and I didn't really protest much. This isn't one of those stories where I've been in love with him since I could notice boys. He was actually just my best friend. We had grown up down the street from each other and were rarely seen apart.

I hadn't seen him in weeks. The first few times I went over his dad tried to convince me he had mono. I knew it was bullshit. Jake's love life was non existent due to one Bella Swan, and here's where it gets decidedly more complicated considering Bella is my sister.

Anyways, eventually Billy realised I wasn't buying his bull so he just told me that Jake wouldn't be able to see me for a while. So it was especially surprising when he turned up just a week after that conversation.

SA **** SA

"Jake?" I said in surprise, and not just from his presence. When I had last seen my best friend he had been lanky 16 year old boy, standing at 5"10, with beautiful long crow black hair. The person before me was a man. A burly man with cropped hair that towered over me at at least 6"2.

"Jake." I said again as he continued to stare at me, his face sullen. Even that wasn't the same, with his newly chiseled jaw and dark eyes where there used to be bright expressive pools. "What happened?" I knew I should've been angry but I found myself moving to the side to let him in, slipping back into my role of best friend and confidant.

He wrinkled his nose as though he had smelt something bad.

"Do you think there's somewhere else we could go?" It was the first word he'd said and it brought me comfort that he still sounded like my Jake.

I nodded. "Just give me a sec." I walked into the kitchen where my dad, Charlie, was nursing a coffee and a paper. His thick dark moustache hovered over his mug.

"Hey," He looked up, seeming almost startled. "Jake's here. We're just gonna go sit and talk."

He nodded deeply, but he was frowning. "Boy dumps you for a month and now you're gonna talk." He muttered. "Stay safe." He said turning back to his mug. Taking that as approval I gave the usual reply.

"Always am." I grabbed my coat and ran out to Jake, shutting the door. He had moved off the porch and it was then I realised he wasn't wearing a jacket. "Jesus." I said catching his attention. "Do you want a jacket?" I asked, pointing over my shoulder, already half turned to go get one.

"No, it's fine." He said quickly and stepped up to me, pulling me into his arms. Though I was caught off guard it only took me a second to wrap my arms around him as well. I could barely get them to meet behind his wide body. It struck me how warm he was for a moment, but all at once I could feel the weird tense feeling I had had for the past month melt away. I had missed my best friend.

"What's up Black?" I asked, but it came out muffled against his chest. I felt him huff a laugh at the nickname, or maybe it was the question, but it sounded bitter and nothing like his full bellied laugh.

"Not much Nessie." He sighed, stepping away finally. I slid my hands into my jacket pockets and we started to walk slowly to Jacob's truck. It was a huge shit bucket, but I thought it was pretty cool Jacob had rebuilt it himself. I slid into his passenger seat and he got in next to me a few second later.

"What happened?" I repeated my question from earlier.

Jake gave me a sideways glance and sighed. "I can't tell you."

I let out an incredulous laugh. "You can't tell me? We tell each other everything." And I meant everything. We knew about each others first kisses, he knew about my first time (I was ashamed to say it had been Mike). We had discovered porn together and he had told me all the joys of male masturbation, even if it was to horrifying thoughts of my sister. We didn't have secrets.

He growled and his hands began to shake. He punched his steering wheel suddenly and I jumped. "I CAN'T!" He shouted, his eyes facing forwards. "I can't tell you anything." He said quieter, but still angry. "You're my best friend and I want to talk to you but I can't!" He smacked his hand against the steering wheel again. It scared me to see Jacob like this. In all the years we'd been friends I'd seen him angry but never like this.

Ignoring my beating heart I climbed over the console and sat in his lap. I wrapped my arms around his shoulders and he tucked his head into my shoulder. This is always what we did when things got too much for one of us. "You can tell me anything Jake, but I wont force you to talk to me." I said, even though I felt deeply offended by him clearly being loathe to the idea. I felt him inhale against my skin and draw me deeper into his arms. He kissed the curve of my shoulder where his face was. The gesture made my heart beat faster as it did when anyone did it.

I felt Jake still beneath me. Tentatively, he did it again and I had to resist letting out a sigh.

"Jake stop." I murmured, but my body worked against me and my head tilted, allowing him more access.

"Why?" He asked but I could hear the smirk in my voice and it made me happy to hear him sound more like himself. He kissed my neck and gain, harder this time, before I could answer.

I couldn't help but let out a gasp and I felt a pool of warmth between my legs. Something began to harden against my thigh and Jake's kisses grew frantic. I began to pant and couldn't resist grinding against Jake. He groaned into my neck and began to kiss his way up my jaw. Maneuvering myself, I straddled him. Jake's lips slowed as they reached my own.

I think we both knew we could stop here, so there was a question in the air. Did we want to? We had shared everything up until that point. We had even kissed a couple of times so why should this be any different. I knew he liked Bella, maybe even thought he loved her, but I really couldn't say I cared at this point. Jake had lit a fire and now I wanted it.

Taking the leap I pressed my mouth solidly against his and he groaned. I lowered myself from where I had been hovering over his lap and pressed my most intimate part against his, rolling my hips. I gasped, opening my mouth to his and our tongues joined, caressing each other. It was gentle at first but we picked up ferocity quickly as our hips moved together.

I ran my hands over his shoulders and down his chest to the hem of his shirt. Pulling away I gasped for air as I pulled it over his head. I surged forwards and buried my face in his neck, sucking and pulling at the skin lightly with my teeth. He moaned beneath me, running his hands through my dark amber hair. They ran down my back and under my shirt, pushing it up until I caught on and raised my arms.

Once my breasts were exposed to the air Jake wasted no time, pressing his lips to the valley between them. I whined, cradling his head and rocking against him, gasping his name when he hit my sensitive bundle of nerves. He licked a path to my right breast, sucking on my nipple through the thin fabric. I moaned again, my hips moving faster over his, sending another flood of warmth to my core.

Groaning, Jake lifted his face from my breast. "You need to stop that Nessie, or I'm gonna come in my pants." His words sent a thrill through me and I reached back, unclipped my bra and flinging it on the seat next to us. His eyes drifted down and he bit his lips as he stared at my rose toned nipples. Before I could allow the heat of his gaze to distract me I untied the laces of my jogging bottoms and with some awkward maneuvering and a headbutt or two, managed to get them down along with my underwear.

I felt like I should've been self conscious but I had known him for so long that it didn't make much sense to me.

We were still laughing as Jake ran his hands teasingly slow up my thighs and gripped my ass in his rough palms. Massaging the flesh he brought his mouth over my nipple once again. Without the barrier of cloth the teased the bud until it was hard.

"Jake." I gasped. "More."

He brought one of his hands over my stomach and ran it down, brushing it over my wet flesh. I let out a small cry and felt his smirk where his mouth rested on my breast.

"Oh shut up." I sighed, drawing a chuckle from him. His thumb ran circles around my small bundle of nerves and I heard myself mewl. His lips drifter up my neck until his mouth was next to my ear.

"You're really wet." He panted, and I bit my lip at how much wetter hearing that made me. His hand drifted down and I felt a digit tease at my entrance.

"Please." I begged, wanting something inside me more than anything. As I brought my mouth back to his I felt a finger slide inside me, all the way down to his knuckle. Our kisses were sloppy as I rode his hand. He slipped another in and I was vaguely aware of the sound of a buckle.

Both of Jake's fingers slipped out of me and I began to whine until I felt a much bigger press at my opening. I looked into his eyes and hovered for a moment before I let myself sink slowly. My eyes fluttered closed at the sensation. Sex with Mike had been okay but Jacob filled me like no one had before and I panted his name as he did.

When my hips were flush with his I paused for a moment, the sound of our pants filling the air and fogging the windows further. It was at this point I realised it had begun to rain heavily. Biting my lip I lifted myself up until only the tip of him was inside me and sank down once more. An embarrassing keen slipped out of me as I rode him.

I began to bounce faster, with Jake's hands on my hips, guiding me. As he began to grunt he slipped his thumb down once again and began rubbing circles on me. I cried out and threw my head back, allowing him to lean in and begin kissing my neck once more. Pressure began to build in my lower abdomen as I bounced hard on Jake's length.

"Come on Nessie," He grunted in my ear, clearly struggling to keep control. "Cum for me baby."

I cried out Jacob's name as my orgasm washed over me. His hand on my hips steadied me as I twitched over him, my walls clenching fiercely. Jake's moans grew in volume until I felt him spill inside me, his hips bucking against mine.

I was draped over his sweaty chest as both of us caught our breaths. Sitting up I kissed his cheek and slid off of him, feeling his essence drip out of me along with my own. We used my underwear to clean us up and got dressed again, sitting in our own seats once more.

The torrential downpour around us was a blessing, keeping us hidden and our unchecked volume out of earshot of the Chief and my sister. As we sat there staring out the window I couldn't help but snort at what we'd done.

I felt Jacob's eye's flash over to me in questioning as my laughter grew. His deep bass joined in until the truck was filled with hysterical laughter. After it had died down I looked at him, happy there was no awkwardness here.

"I should get back before my dad sends out a search party." He nodded. "See you around, Black." I said, draping my jacket over my head and preparing to run for the safety of the house.

"You bet, Nessie." Jake smirked and I opened the door, sprinting through the rain. I heard Jake's truck putter off behind me as I entered my home.

"Where were you Ness." Dad's gruff voice called, this time from the sitting room.

"Jake and I sat in his truck when the rain started." It wasn't an outright lie but it still made me uncomfortable. I kept my face turned from his, busying myself with hanging up my coat. He grunted and I breathed a sigh of relief as I ran up the steps to my room.

I couldn't hear anything from my sister's room and I figured she was already asleep. As I quietly shut my door I wondered it she would make it through the night without waking the house. Changing into my pyjamas and lying down in my small double bed I began my nightly mantra of hating Edward Cullen for the state he left my sister in. However, my last thought before I fell asleep was what would become of this thing Jacob and I had started.


A/N So, what do you think? Liking it so far? Give it a review if you do. As I'm sure you've noticed there's been an influx of words from me recently. You and me both hope it lasts.

Adios
