I grunted as my hardened member was sheathed in her tight heat. When I fully slipped inside I stilled, allowing her time to adjust to the size of me. She moved her hips and I groaned as I held her to me firmly. I pulled out until just the tip remained and pushed forward until I was buried deep inside her pussy.

I pumped into her at a steady pace, slowly building up speed until I was pounding into her relentlessly. I gripped her hips and pulled her to me as I thrust forward. She screamed and fisted my sheets as I fucked her hard and fast, just the way she liked it. I loved the feel of her wrapped around me, screaming my name as I gave her the release our bodies needed.

"You like that, Baby," I asked thrusting harder.

"Oh, Jacob," she whimpered.

I pulled out and flipped her over onto her stomach. I gripped her hips and lifted her up until she was on her hands and knees. I grabbed my cock in one hand and held her in place with the other. I plunged my dick back into her pussy, growling at the tightness from the new position.

"Oh Fuck!" She yelled.

"God Bella, you are so fucking tight," I snarled.

I shoved my cock into her forcefully, fucking her like the animal she told me I was in the sack. I pulled out again and stood up; she whimpered and looked at me over her shoulder. I licked my lips as I stared at her glistening slick folds. I crooked my finger at her, beckoning her to me and she crawled towards me. I grabbed her around her waist and hoisted her up into my arms.

I spun us around and pushed her into the corner of the wall. I slammed her back down onto my cock and her screams were muffled with my mouth. I slipped my tongue between her lips and fucked her with my tongue to match my thrusts. I pumped her up and down on my shaft grunting and growling each time I filled her completely.

Her walls clenched around my member like a vice as I licked the column of her throat. Her orgasm washed over her in waves of pure bliss as I bit down where her shoulder and neck met. My cum shot out of me in hot spurts, coating her insides.

I released the muscle and kissed the spot I bit. Seeing my mark on her released something primal in me and I was instantly hard again. She lifted her eyes and stared at me with a smirk. I raised my brows at her as she swiveled her hips. I wrapped my arms around her and walked us to the bathroom.

"You know it's a good thing we're alone," I chuckled. "Although, all of La Push may have heard you though."

She blushed a beautiful shade of red and buried her head in my chest as I turned the nozzle and let the water warm up. I stepped into the shower with my girl wrapped up in my arms. Standing up the spray, I lifted her up and down my hardened member slowly.

"Happy Birthday Jacob, I love you so much," she murmured against my lips.

"I love you too, Bella, forever," I whispered.

We reached our orgasms together and then I washed us up and shut the water off. I stepped out of the shower and lowered her to her feet carefully. She stood on shaky legs as I dried her off. I wrapped a towel around my waist and scooped her up, walking us to my room. I sat her on the edge of my bed and slipped one of my shirts over her head. Bella put her arms through the sleeves and sprawled out on her back.

I climbed into bed with her after I put on my boxers and curled my body around hers. We fell asleep quickly and I awoke some time later with a gasp. I hated that stupid dream of me running around the woods on four legs instead of two. I was burning up and had a light sheen of sweat covering my head and chest.

I untangled myself from my sleeping angel and got out of bed. My muscles ached and I felt tense. I threw on a pair of shorts and walked out of my room silently. I closed the door with a soft click after stealing one last glance at Bella and went into the kitchen to get some water. My dad was at the table talking to Sam. I glowered at him and turned my back on them.

I could feel myself shaking at seeing him in my house. I slammed down my glass and stormed out of the house. I stomped off into the woods and tried to calm myself. Ever since that fucker disappeared for a few weeks and then came back the council treated him like he was some sort of gift to the fucking tribe. I hated him with a passion that burned inside me.

What pissed me off the most was that Embry couldn't stand Sam and now he hangs around with the La Push gang like they had always been the best of friends. I could feel the rage burning like hot coal in my blood and I clenched my fists. The shaking intensified and I could feel my form blurring. I let out an anguished scream and dropped to my knees, trying to gain control of my emotions.

I heard a snuffling noise in the distance and I burst forth into the animal within. I growled and snarled as I ran further away from my home. I could hear voices in my head and I ignored them as I continued to run.

Jacob stop running.

A voice I didn't recognize pissed me the fuck off telling me to stop. I bared my teeth and pushed my legs harder. I couldn't figure out why I turned into a fucking animal, but I'd be damned if I was going to sit around and let someone I didn't even know tell me what to fucking do.

Jake please, it's me.

My steps faltered as I recognized the voice of Embry. I stopped and looked around, seeing nothing. I turned my head in the direction of my house and knew that I needed to get back to Bella. She would be waking up soon and I wanted to be there when she did.

You can't be around her until you can control yourself Jacob.

And who the fuck do you think you are to tell me who I can be around? – I barked out.

Four wolves emerged from the trees and I stopped to stare at them, sizing them up. I wasn't sure how big I was, but I'd fight all of them to get back to my girl. I growled, showing my teeth and inched closer to them, searching for an angle to attack.

It's me, Embry.

A gray wolf with black spots took a tentative step towards me. I cocked my head to the side and looked at him. I turned my gaze on the other three wolves and I was suddenly bombarded with thoughts of the tribe's legends and knew what the fuck happened to me.

I'm Sam.

The black wolf inclined his head and I snapped my razor sharp teeth at him. I fucking hated him and I would burn in hell before I spent any of my time with that bastard.

I'm your alpha. You don't have a choice but to spend time with me. – Sam snarled.

Fuck you! You are nothing to me. – I stared him down. I'm out of here and I dare you to try to stop me. I said, my voice taking on a strange timbre.

I watched as the wolf I knew to be Embry sink down on his belly. The silver wolf and the brown one whined and looked to Sam. I bared my teeth and rammed my body into Sam's as hard as I could. I shoved past him and took off running towards my house.

It wasn't until I could see my home that I suddenly realized I was still a gigantic fucking wolf and had no clue how to get back to my human form. I stopped just inside the trees and sat down, fuming that this shit happened to me. I watched as Bella walked out the back door and sat on the porch, looking towards the woods with a frown.

I'm here, Baby. – I thought to her.

She took a sip of her coffee and her eyes snapped to mine. I felt myself stand and began walking towards her. It was like I had no control over my legs. I tried to stop, but it was futile. I emerged from the cover of the trees and she gave a small gasp, but made no move to flee.

I kept my eyes on hers and dropped to my belly, scooting closer to her. She studied me for a moment before she lowered her mug and placed it next to her. She stood slowly and regarded me carefully. I whined low in my throat and made little whimper sounds.

"You won't hurt me, will you?" She asked cautiously.

I shook my massive head no and she gave me a small smile.

"You understand me?"

I nodded and scooted a little closer to her. She reached her hand out and I extended my head, licking her fingers. She giggled and bit her full bottom lip. I inhaled deeply and my eyes rolled back. She smelled so delicious, a mixture of the two of us.

I pushed my head into her hand and she ran her fingers through my hair. I felt a rumble begin in my chest and she covered her mouth with her free hand.

"You like that don't you? I wish my Jacob could see you; he would be as mesmerized as I am. You have the same color eyes that he does," she smiled.

I heard the other wolves approach and I swung my head around to glare at them. I'd rip them to fucking pieces if they came closer.

Stay the fuck away from me and Bella. – I growled out.

I turned back to my girl and she was looking towards the woods. She took a step in the direction of the others and I put my head against her stomach to stop her. I didn't push her because I was afraid I would hurt her, but I wasn't about to move either.

"What's wrong? Is there something in the woods?"

I nodded and prayed she would believe me. I didn't want those fuckers anywhere near her. She narrowed her eyes, but sat down next to me. It thrilled me that she was so comfortable around me, but unnerved me at the same time. Where was her self-preservation?

She slowly leaned against me and that strange rumble noise started up again. What the fuck? It almost sounded like I was purring.

"Are you purring?" She wondered.

I let my tongue flop out and gave her what I could only hope was a wolf grin. She snuggled into me with a giggle and began petting my neck. I closed my eyes and marveled at her touch. She rested her head on my shoulder and we stayed that way until she shivered with the wind. I curled my huge body around hers, trying to warm her up.

I felt so content and at peace with my girl. She relaxed against me and all of a sudden there was this strange shimmer feeling running over my body. Bella gasped and I realized I was me again.

"Jacob!" She exclaimed.

I stared at her and it was like nothing else existed but her and I. I could hear voices in the background, but I couldn't care less what they were saying. I was in awe of her beauty; it was like I was seeing her for the first time. I felt tears prick my eyes as my love for her grew tenfold.

"I think you just imprinted on Bella, Son," my dad's voice broke through to me.

I pulled her into my arms and kissed her with all the love and passion I felt for her. She gasped into my mouth and slid her hands into my hair, running her fingers along my neck. It never dawned on me that I was naked until my cock brushed up against her jeans. I hissed and wrenched my lips away from hers.

My dad tossed me a pair of shorts and I slipped them on quickly. I had Bella back in my arms before she could blink and she giggled, holding me close.

"I don't know what's going Jake, but I feel like my heart is going to burst with the love I feel for you. Why were you a wolf?" Bella asked, leaning back to stare into my eyes.

I lifted her into my arms and carried her over to sit by my dad. He told her the legends and explained imprinting to the both of us. I was also informed that when I was ready it was in my bloodline to be alpha of the pack and chief of the tribe.

I glared at Sam, challenging him with my eyes to say anything about being my alpha. We continued to stare at each other until Bella pressed her lips to my neck. I looked down at her and smiled, not exactly the day I had planned for my 18th birthday, but shit happens.

While I appeared to be happy, the animal within was plotting ways to take out the black wolf that was standing in my way of claiming my rightful place as alpha. I smirked up at him and let him know with my eyes that he better watch his back.
