Chapter 1

It was a dreary, rainy day outside the Gryffindor common room, where Fred and George sat plotting their next prank. It had to be a big one, and preferably, it would involve getting their stubborn younger brother Ron and his bushy haired best friend Hermione together. They were both stubborn gits in Fred's opinion, the whole school knew they liked each other, except, it seemed, Ron and Hermione themselves. But Fred was determined to change that, and he had an idea.

"Hey George!" he said to his twin, "I've got the perfect idea to get Ron and Hermione together!"

"Great Fred!" said George, "what is it?"

"Let's just say it involves swimming pools, and bikinis," Fred grinned deviously.

"I like the way you think," George said, smirking at Fred. They high-fived. "Where to, brilliant brother?"

"A little room I like to call, the Room of Requirement."

"Brilliant!" George exclaimed, "Why didn't I think of that?"

"Because, my good brother, I am the smart one."

Fred and George left the common room and walked down the seventh floor corridor, to the stretch of blank wall opposite the tapestry of Barnabas the Barmy trying to teach trolls to do ballet. Fred walked past the wall three times, all the while thinking, I need a giant swimming pool…I need a giant swimming pool…I need a giant swimming pool.

Fred opened his eyes and saw, to his great satisfaction, a large door where the stretch of wall previously was. George opened it and they stepped through to find themselves on the edge of an enormous pool.

"Wicked!" they both said at the same time.

The next night, Fred and George were telling Harry, Ron, Hermione, and Ginny about the pool.

"You shouldn't have done that!" Hermione cried, "The room is intended to help us! Not for our personal enjoyment!"

"Silly Hermione," Fred chided, "It is helping us! Our enjoyment is just an added benefit!"

Hermione rolled her eyes at their antics.

"But," George added, "it is helping you much more than it is going to help us." He grinned mischievously.

"What do you mean by that?" she asked skeptically.

Fred and George just kept grinning and shook their heads. Fred added, "You'll find out soon enough."

"Well, I think it sounds fun!" Ginny said in an upbeat voice. Harry and Ron nodded in agreement.

"Perfect," Fred said, clapping his hands together as if that settled it, "When do you lot want to go?"

"Now!" Ron said excitedly.

"We can't go now," Ginny argued, "we have to at least get swimsuits first, and we have to go at a time when no one will question why we're gone, like maybe some Saturday."

"Okay," Harry agreed, "as long as there is no Quidditch practice I'm missing."

Ron nodded in agreement, "Well, we have a Hogsmeade weekend this Saturday, so we can get swimsuits then."

"Perfect," George said, "and we can go to the pool next Saturday."

"Guys," said Hermione in a tentative voice, "I still don't think this is such a good idea…"

"Aw Hermione, don't be such a spoilsport!" complained Fred.

"Yeah," added George, "it will be tons of fun!"

"Besides," whispered Ginny, so that only Hermione could hear her, "I bet Ron'd love to see you in a bikini!"

Hermione looked at her, aghast, "I'm going to bed," she stated, and she rushed off to the girls' dormitories.

Ginny smirked as the rest of them bade goodnight to each other and left the common room to go bed. Once everyone but Fred and George had left, Fred grinned to George in excitement, "this is totally going to work!"
