I'm aware that Katie Bell is actually a year younger than the twins and would not have been attending Hogwarts in their first year. But, considering I've changed what I have to tell this story, I think we can all accept this.
Staying the same just makes everything change
"All right, hold on." Charlie said huskily.
"Hold on to what, exactly?" Ivy smirked at him. She was blind drunk and had Flooed Charlie over for a quickie.
Ivy's legs were over Charlie's bare shoulders. Her back laid flat on the edge of her bed and Charlie was trying to find the most comfortable way to stand before he entered her
She took this pause to look the Weasley over. Charlie had a tanned, broad chest that just look perfectly rock hard as they shone with sweat.
Fred's got some pretty board shoulders; I bet he looks a lot like Charlie naked, Ivy thought to herself.
She looked at his hard, thick cock and felt herself get wetter at the thought of it inside her, but couldn't help but think about what it would be like to have sex with Fred.
They looked a lot alike. They were a lot alike, really. Charlie was always at ease and able to joke around, much like the twins were. But Charlie didn't have the callousness that Fred did. Charlie was much more gentle and relaxed. Everything was casual with him. Fred liked things best when they were a spectacle. Every relationship of his were drama-filled and always ended with a bang.
In this moment, Charlie was fiddling with their position.
"I think you need to be on a higher surface." He said.
"I think you need to just stop and fuck me already." Ivy was getting impatient.
"Whatever the lady says." And with that, Charlie entered her, ramming her into the mattress.
Ivy moaned in pleasure. Charlie was going so hard that it almost hurt, but she didn't mind.
"Faster?" He asked.
"Go as fast as you want, this is amazing."
Charlie pulsed into her, this time faster, and then faster, until she came, and he right after.
"Oh, Fred." She moaned quietly.
It was at the mention of his brother's name that Charlie began to feel horrible.
He and Ivy always had a casual, no romantic feelings involved, sort of relationship. When he was in town, they'd hook up. It was as simple as that. Every once in a while, they had to be friends to one another, but aside from that, they weren't completely invested in each other.
They liked it like that. Charlie was never looking for more than to get off, and who better than with a pretty girl he knows pretty well?
Ivy was a bit more complicated than that. Ivy, in some deep part of her, was looking for comfort. She was looking for some other feeling than loss, and Charlie was able to give her that. He was also able to give her a sense of accomplishment and confidence. If she couldn't have the Weasley she wanted, she was at least fucking one of them.
"I knew this would happen." Charlie said, cleaning himself up.
"What d'ya mean?" Ivy slurred.
"I'm just a surrogate for my brother."
Ivy stared at him.
"I knew this. I knew this four years ago," He started, "I knew you were in love with him. I just never thought that I'd be some sort of placeholder."
"You're not a placeholder."
"It's ok, Ivy. I don't really…mind at all. This has been fun. But all this is doing is hurting you. I think you think this is as close as you'll get to being with Fred."
"Charlie," Ivy said with inflection on the end of his name, "I never thought that. I just thought we were having fun."
"And we were. But I don't think this is helpful to either of us."
"What, then?"
"I think you should go to bed, sober up, and think about things for a while. Just call me when you want to talk about it."
"But—"
"Trust me. This is for our benefit." Charlie got up and went into Ivy's fireplace, and like that, he was gone.
Ivy was bummed.
She wasn't anything else. She wouldn't let herself be anything else.
So she did what she always did when she had to pass a night by herself.
Charlie might have just ended whatever they were doing.
She took a shot.
She was in love with Fred.
Another shot.
But both Fred and George, as much as they wanted to reconcile, have moved on.
And another.
Before Ivy knew it, she had Apparated outside the flat of her favorite set of twins.
She knocked loudly.
"Geeeeeeoooooorgggiiiiieee." She called. "Georgie, open up!"
A minute later, the door opened, revealed a disgruntled, pyjama-clad George.
"Ivy, what are you doing her? It's two in the bloody morning." He moaned, his voice laden with sleep.
"I have things I need to tell you." Ivy slurred out.
"Are you drunk?"
"Barely. Is Fred around?"
"He's at Katie's."
This stung Ivy.
"Good. I have secrets."
George fixed Ivy and himself up with a cup of tea and a plate of Christmas cookies his mum had sent over. They sat in the kitchen.
"All right, Ivy, what are these secrets?" He asked, slipping a Pepper-Up Potion in her teacup.
"I've got a couple."
"Well then, start with the first one."
She took a sip of tea. "I'm not sure if I should—"
"—Just. Tell me."
"I'm in love with Fred and I've been fucking your brother." She spat out as quickly as she could.
"What. You've been sleeping with Fred?"
"No, I'm in love with Fred, I've been sleeping with Charlie."
"So Charlie's the mystery man? For how long?"
"You know how you found that underwear at mine?"
"Ugh, no! I touched those and now you tell me they're my brothers?!"
"Would it have been better if they were someone else's?"
"I supposed not."
Ivy was sobering up with every sip, and with every bit more sober she became, the more and more she regretted telling George anything.
"So if you're in love with Fred, why have you been sleeping with Charlie for so long?"
"Lots of reasons, I suppose. To stop loving Fred. To feel better about other things. To prove someone wanted to shag me. I think I've just been using sex as a placeholder for love, though." She said, using Charlie's words.
"How long have you been in love with Fred?"
"How long have we been friends?"
"No. That long? Why didn't you ever do anything?"
"Because I knew he'd never feel anything back. He always seemed much more interested in other girls. Remember how surprised you were when he and Katie started dating? He's been eying her since first year."
"So, what do you like to do?" An eleven year old George Weasley asked his fellow Gryffindor first years at breakfast.
"I like Quidditch." Angelina Johnson said. "My family and I play all the time. I'm a good flier. You'll see when we all take flying lessons."
George grinned. An outsider would be able to pin this down as the moment George fell in love with Angelina.
"I like Quidditch, too! I always play Chaser with my brothers!" Katie Bell exclaimed excitedly.
Fred likes to think of this as when he fell in love with Katie.
"Do you like Quidditch?" One of the twins asked Ivy.
"I—I don't know. My mum's a witch but she and Dad raised me as a Muggle. I'm not really sure what it is."
"It's the best thing in the world!" Fred said.
"Nothing feels better than flying around, hitting things about." George said.
"I dunno, I'm not all that comfortable with heights."
"I'm never scared." Katie Bell said.
"Me, neither. I just get uncomfortable." Ivy spat.
The twins talked to Angelina and Katie for the rest of breakfast about their favorite Quidditch teams. Ivy sat in silence, wishing she knew more about the sport.
"Oh, Merlin. Things make so much more sense." George said. "The Yule Ball, us leaving Hogwarts, the war… Ivy, I'm so sorry. I never realized."
"I've been trying not to be obvious about it."
"Am I the only one who knows?"
"Charlie knows. And no one else ever will." She said.
"What do you mean?"
"George, I'm not going to get over it. I'm not going to forget when Fred tried to teach me how to fly before flying lessons. I'm not going to forget when he punched Cedric Diggory when he broke up with me. I'm not going to forget that he was my first kiss, or how much it sucked when he and Angie went to the ball when he promised me, or how much it hurt when he left Hogwarts."
"I left, too."
"I know, but I don't love you like I do Fred. I just don't want him to go live this happy life with someone else, while everyone looks on and wonders how jealous I am."
"Then tell Fred."
"Yeah, 'cos that's not stupid."
"It's not. Listen, Fred says he's in love with Katie, but he's not. There's no way my brother would fall in love with that girl. She's lovely, yes, but dumb a Death Eater, and boring to boot."
"Fred's happy, George. I'm not going to be the one who ruins that."
George smiled at Ivy, and although it was a sad smile, it was something.
"Oh, bloody hell." He cursed moments later.
"Hmm?" Ivy asked, gulping down her tea.
"Last year, Charlie was telling us about some bird he'd been shagging. It was you, wasn't it? Shit. He gave us a lot of details on that!"
Ivy grinned. "Don't worry. I've given Angie tips."
George looked at his friend, his mouth agape.
"Charlie wants to stop, anyway. He thinks I'm just using him as a surrogate for Fred."
"Are you?"
"No. Charlie's really good, and really hot."
"Merlin!" George did not want to hear about his brother's performance with Ivy.
The two talked into the morning and fell asleep in the twins' living room.
Until they were awakened by deafening crack.
"George? Ivy?" Fred's voice forced the two to open their eyes.
"Fuck, I meant to leave at some point." Ivy muttered groggily.
"That was probably," George scratched his head, "four hours ago. Probably in between pumpkin juice with mead and spare ribs." He said once he looked at the coffee table in front of them.
"Where did that even come from?" Ivy laughed.
"I think when you were telling me how perfect Angelina is for me, I suddenly wanted something to eat."
"Was I crying then?"
"Yes, you were."
"Brilliant."
"What is going on here?" Fred finally spoke.
"We're just hanging out." Ivy said.
"Like we used to." George added. "How was Katie's?" He asked.
"Fine. We had dinner and then headed to bed. Nothing much happened."
"Oh, gross, Fred." Ivy said. She didn't mean it as jokingly as the twins thought she did.
"No, we didn't do that. Katie is the kind of girl—"
"—that wants to wait?"
"—that wants to be romanced?" Ivy and George's responses overlapped each other.
"Well, yeah. Probably to both."
"Aww, is Katie immune to the Fred Weasley charm?" Ivy cooed.
"She must be. We hardly even kiss."
"But you sleep in the same bed?"
"No, I slept on the couch."
"Oh." Ivy said. Her insides were doing somersaults. Maybe Fred and Katie wouldn't be together for much longer.
"It doesn't matter, though. It won't be long until," Fred fidgeted around in his pocket, "this." He produced a small white box. It shimmered in the sunlight.
"You picked one out?" George asked.
He cursed himself that he didn't tell Ivy in their conversation that Fred was planning on proposing to Katie. Ivy looked crestfallen.
"Wow, Fred. That's beautiful." Ivy muttered as she looked at the ring he had chosen.
"Isn't it? I think she'll like it." He said, grinning.
"Yeah. I've got to go." Ivy got up from the couch.
"But I only just got here!" Fred said.
"Ivy's got work, right?" George said, knowing that she didn't want to hear about how Fred was going to propose to Katie.
"Work. Yes. I've got to go to work."
Ivy Disapparated without saying goodbye.
"What's wrong with her?" Fred asked.
"Man stuff." George mumbled.
"Man stuff? Is she seeing anyone?"
"Sort of. Not really. It's just how Ivy deals with things."
"Does it have to do with those boxers?"
"A little bit."
"She tell you whose they were?"
"No," George lied, "but I think she's in love."
