AN: As you may know, Charlie doesn't have a canon girlfriend, but that doesn't stop me from giving him a girl.
This will not be a full story, it'll simply be a collection of oneshots and short stories, you could call it a jigsaw-puzzle of a relationship. It is not chronologically or anything and will run from his early childhood up until right before the war ends.
Part of the Casey Chronicles.
Rated for violence, rage, sex, masturbation and a whole lot more nastiness, but will also contain cute spots and moments of pure bliss. Don't say I didn't warn you.

To the untrained eye, one could only assume the two naked teenagers on the edge of the lake was a couple. The truth was much more complicated.

The girl was sitting with her legs crossed, leaning back on her hands to let the sun dry her body and long locks of dark brown hair. The boy kept shooting sideways glances at her, sitting in much the same fashion, but with his legs straight out in front of him. His fifteen year old body was broad-shouldered and tuned by hours of quidditch, the sun had left a thick pattern of freckles over his otherwise pale skin and his short hair burned red in the light.

"Charlie?" She said after they had spend too long in pleasant silence.

"Yeah, Kay?" He now had a good excuse to look at her as she shook her almost-dry hair with one hand.

"I'm hungry." She ran the tip of her tongue over her pale purple lower lip and he followed the movement with his eyes.

"Then we should head back, bet Mum's got something cooking." He had been drawn between food and spending more time with her ever after they came up from their swim. She reached over to her heap of clothes and withdrew her wand.

"Charlie..." She shook her hair out of her face, making it glitter. "I have something to tell you, it's kinda important." His heart jumped in his chest, maybe she would give him a chance after all. "I'm... I'm a vampire," she got out.

"I know. Still, you sit right here in the brightest of sunlight!" He had known for years without her voicing it our.

"How long have you known me? Almost ten years. Have you ever seen me age? The sun-thing is just a myth." She swallowed hard, hoping he wouldn't get mad at her for not saying it earlier, but he had been just a child until suddenly he was almost an adult. "The reason I told you now is... Well, could I drink of you?" She felt sheepish putting it like that.

"Yeah, sure," he answered and she reached for his hand. He inclined it towards her and she got up on her knees, took his hand in both of hers and made a small cut on his wrist with her wand. He enjoyed the feel of her hands on his and a shiver went down his spine when she put her lips to the cut.

She drank with a forced control, knowing she couldn't give in to the urge of biting. He didn't know how long she licked on his wrist, he was delighted to watch her and feel her cool fingers to his palm while he ran his eyes over her body. She was leaning forward, her breasts having a small cleavage he desperately wanted to touch, but didn't. Her waist was slender and ended in firm hips, the skin gliding over them if she wriggled in that way. He made himself think of other things as he began getting excited and stared at the sky instead.

"Thanks," she said when she pulled off and healed the wound. He smiled at her, glad to be to her service.

That night Charlie had trouble sleeping. He had long ago come to terms with her being a vampire, that wasn't what bothered him. He stared into the wall and heard his older brother breath steady in the other bed across the room, suddenly very unhappy he had to share a room during the holidays so his sister could have one for herself.

His mind kept playing the memory of her lips to his skin and how she had pushed her bosom slightly towards him, two strutting nipples catching his attention before she rose a bit, making her hips glide forwards and into his embrace. This time he let himself get aroused by the image. Her full lips kissed at his wrist as she looked at him, he returned it and stared into the pale green irises with a ring of yellow for a long time before his look again glided down to her breasts. His hand went down the front of his pyjamas-bottoms, gripping hard around his erection.

He really shouldn't, but when he saw the eyes, lips, breasts, everything in his mind, he couldn't help himself. His right hand went fast up and down his cock, his breath growing heavier as the image became clearer, her muscular thighs and round bottom occupying his mind. He was enjoying himself most enormously when a pillow was slammed down on the side of his head.

"What the hell?" Bill hissed at him.

"I thought you were sleeping," Charlie said to his defence.

"I was trying," Bill answered and smacked him with the pillow again. "What do you think you're doing anyway? If you have to wank that badly, at least go to the bathroom!"

"Fine, I'm going," Charlie answered grumpy and got up. Bill rolled his eyes when seeing his brother's trousers stand out like a vertical tent, but took his pillow and got back to bed. Charlie stormed out the door as silently as he mastered, the rest of the house should be sleeping at least. He went up the stairs and entered the bathroom with a long exhale, some of the mood was gone. He placed his hands on the sink in front of himself and stared into the mirror on his naked torso, years of quidditch and outdoor activity had really paid off, Kay had said it herself. Just like she had ran her tongue against his wrist. And shook her hair back with a throw of her head after dinner.

His hand went down in his pants again as he remembered her tight white shirt, snuggling neatly around her curves. They were alone in the kitchen and she perched herself on the table, leaning back on her hands while eyeing him, her eyelashes fluttering as she crossed her legs slowly, pushing her breasts forward until three of the buttons bounced right off. He took a step towards her, smelling her sweet scent and she uncrossed her legs again, running her palms up her thighs and laying the small skirt aside, revealing the inside and lack of underwear.

"Please me, Charlie, please me," she whispered slowly and he got up close, she moaned as he penetrated and began thrusting, feeling her moist flesh around his cock. She kept moaning as her legs went up around his waist and he gripped harder at her hips, breathing heavy.

"Fuck me, Charlie, fuck me hard," she shouted and tightened herself around him. He brought his shaft deeper and deeper into her, making her moan loud. His hand slipped off his cock a moment, but he quickly regained control and saw he breasts bouncing against his moves. He kept going, faster until she screamed in pleasure and pulled them completely tight.

His shout caught in his throat as his back tensed, her breasts bouncing against his chest and she pressed her lips to his as he came, damping his trousers. His stomach fought to take deeper breaths as he leaned heavy on the sink with one hand, pressing his eyes shut. For several minutes her face swam in his mind.

In the end he had to get some sleep and washed his hands slowly. Back in bed he let reality hit him: it would never be the two of them.
