Can't Stop This Thing We've Started

Part 1: Truth Doesn't Make Noise

Renesmee was finished growing. She was sure of it. Her mother insisted that her notions could be wrong, and that she could very well still have quite a bit of growing to go. But she knew it was just wishful thinking on her mother's part. She could feel it in her bones, in her...blood. She had grown up far too fast, even for her standards. Sometimes she wished she could slow down and catch her breath, but someone else seemed to have a different wish for her.

When puberty caught up with her - when she started to grow breasts at the ripe old age of five and a half - she knew she wouldn't have much longer. Her mother had a look of fear in her eyes when she handed Nessie her first bra. Nessie could never understand fully why her mother was so desperate for her to stay a child for just a bit longer. Her mother knew this day would come eventually. She knew that Nessie would stay young as a teenager forever - and yet it still scared her. Maybe you had to be a mother to comprehend what was going through Bella Cullen's head.

After her seventh birthday, two months ago, Nessie felt things change drastically. It wasn't her physicality that was changing anymore, but her view on the world. Her maturity was really hitting it's strides now that she knew she had no more aging to go. Although, Renesmee had always been mature, it was different now, because she knew it. Her understanding of her life was becoming clearer than it ever seemed.

Nessie sighed dramatically as she slammed the book she was reading shut. She lay on her stomach at the foot of her bed, waiting. She felt anxious and she was unsure of why. No matter what she tried her stomach seemed to be constantly knotted and she had no idea why.

She was alone in the house. Everyone was out and about doing their daily activities.

Her mother and father were attending a university in British Columbia along with Jasper and Alice. Rosalie and Emmett were visiting Portland for the day. Esme was in town shopping for more food for Nessie and Jacob, (since hitting puberty Nessie had discovered the wonders of food - although she only appreciated it when she ate along with Jake - blood still seemed to be appealing, though). And Carlisle was at work, doing doctor things.

Nessie was bored. This is how it was often: her, alone in the house, waiting anxiously for something to happen - something she was completely unaware of, but at the same time was so aware of it that it made her constantly nervous.

A few years ago - when Nessie began to notice the opposite sex and the effects that it held with her family members - she realized she no longer liked sharing a house with her parents. It was too weird. So she had moved to the main house and now occupied her father's old room.

Alice and Esme had made it less of a boy room and more of a girl's room. Nessie's aunt had fully stocked the closet with clothes that would clothe her for another twenty years if need be. Her bedroom's walls were now a deep red - just like she asked for. The trimmings were white just like the ceiling. Esme had easily ripped out her father's old thick golden carpet and re-stored the hardwood floor underneath so that it appeared shiny and new. The shelves on the west wall that had been occupied by Edward's CD's had been replaced by various books, CD's, movies and random objects that Nessie had acquired over seven years. She hadn't had nearly the amount of time as her father to collect his mass weight of collections.

Her wrought iron four-poster king-sized bed was in the center of the room against the east wall. The duvet cover was a deep black and the pillows were colours of red and purple and white.

She felt her heart-beat accelerate when she heard Jacob's wolf-form head toward the house. She smiled - yes, something to do! She had been so bored that she was going to search him out soon enough anyway. She loved Jacob so much. He always knew how to make her smile and turn a regular situation into an awesome one.

Jacob turned back into a human, and pulled on his pants as he jogged lightly up the porch-steps and threw the back-door that entered through the kitchen. Jacob had no trouble smelling out Nessie - he knew her scent well. He took the steps two at a time and eventually made his way to the third floor, right outside her bedroom door, which was shut.

He knocked lightly and heard her giggle and her voice say, "Come in." He grinned and entered. He saw her and his whole face lit up like it always did.

"What'cha doing, Ness?" Jacob asked making his way to her. Water droplets cascaded down his half-naked body, reminding Nessie that it was raining. She glanced out the window and saw that it was true.

Nessie shrugged. "I'm bored," she said. Jacob nodded and sat on the ground at the end of her bed. He leaned his head back so it was resting on the bed just inches from her own face. Nessie began playing with his damp hair.

"There's not much to do on a rainy day," he agreed, closing his eyes at the calming feeling of her fingers running through his hair. He felt a shiver shake his body; it wasn't caused from the cold November day outside.

"What have you done so far, today?" Nessie wondered. She considered braiding his hair, but thought against it. "You should cut your hair, I hate it when it's long."

"I'll get on that," Jacob muttered, knowing full well that he would ask Emily to cut it as soon as she could when he reached home later. "I didn't do too much...I hung out with Embry - he just broke up with his girlfriend, again."

Nessie nodded, pursing her lips slightly. She felt nervous again. She was hoping that Jake would change that once he was here, but she only felt the butterflies in her stomach flap their wings faster. Urgh! Stop, she begged them. They didn't listen to her, of course.

She groaned, and Jacob quickly looked up at her to see if she was okay. He saw her frustrated expression and reached out and touched her cheek. She grabbed his wrist and showed him what was upsetting her.

"Nervous?" Jacob asked. "About what?"

"I don't know!" she complained. "I've been feeling this way for a while now. It feels like it's been sitting in my stomach for longer than I can recall. I think I only have just realized it, though." She pouted and rested her head on the bed, staring at Jake with a tortured expression.

He frowned, hating seeing her in any form of distress. He caressed soothing, soft circles on her cheek with his big thumb. She smiled slightly, feeling calmer already.

"Jake," she whispered quietly. He looked at her, curiously, waiting for her to continue. Her eyes were closed as she contemplated her actions. She had an idea - a thought - and she wasn't quite sure how it would play out. It was the only solution she could come up with at the moment. It was the only thing that made sense. She had a feeling that what she was about to do might settle the nerves in her gut. She opened her eyes and stared intently at Jacob's face. Their eyes locked and she felt that what she was about to do, could work.

Their faces were very close, so it wasn't difficult for her to lean forward and press her lips to his.

Jacob was shocked.

Nessie pushed her body closer toward him so she could kiss him easier. Jacob's head was at an angle as she held onto his face and continued to kiss him and attempt to deepen it. This felt right to Nessie. But even though it wasn't settling that knot in her stomach, it felt good. It felt amazing and life-altering, in fact. She moved her lips against his and wondered why he was so hesitant about this. He was moving his lips slowly and carefully - she wanted him to catch up with her! She held onto his neck tighter and pulled him closer to the bed so he could be closer to her.

Her whole body was alive, humming, buzzing. Her head was all foggy and dizzy and she loved it. Jacob's hard, rough, burning skin felt soft against hers.

Finally, he began to respond to their tingling bodies, by maneuvering his own so he was now on his knees and leaning over her sprawled out body across her bed. Only just seconds ago she was in control and now she wasn't. Jacob smiled into their anxious lips and intensified the kiss by slipping his tongue inside her mouth.

Nessie moaned, which seemed to only drive Jacob crazy. He leaped onto the bed, without making it squeak in protest, and hovered over her body. He resumed kissing her, and Nessie found that the only thing she could really think of doing was wrapping her arms around his neck and pulling his face and body closer to her own.

The only thing she could really think of was him. She had even forgotten her name because all she cared about was bringing him closer and that was all that really mattered.

This was it. This was what Jacob had wondered about and waited for for seven years, two months, three days and four hours. He had only been having these not-so-innocent thoughts in the last year or so. He had tried to push them away but he knew that eventually things would change. And suddenly they did.

He ran his hand up and down her left side, grazing her breast lightly, making her tremble. Jacob leaned into her body, making her gasp. He grunted, satisfied that he was making her pleased.

Their fevered kisses, began to slow as he rested on his side, and pulled her onto hers. They lay there kissing softly and slowly, still unaware of what had really just happened. Things would never be the same. They could never go back. They had let go of everything that had kept them from reacting this way a while ago.

Subconsciously, she knew that she was always in love with Jake. That was why her insides had been so muddled for the last while! Now she knew consciously.
