I had a lot of contemplating to do with this story, but I've figured it out now :)

Thankyou for the reviews :) I appreciate them XD

Here's chappie 4:

Sirius led the way to an empty classroom, his heart thumping hard against his chest. He had to tell James. He needed to tell his best friend because he was so confused. When they got into the classroom, Sirius closed the door behind them and pointed his wand at the door.

"Muffliato," he muttered, and then turned to James who was waiting expectantly for him to say something.

"So?" James asked, raising his eyebrows. Sirius fiddled with the hem of his shirt. It was so difficult to admit to.

"I... er... well... you can't repeat what I say to anyone," Sirius said. "Especially not Remus."

"I won't tell anyone," James said smiling. "What is it?"

"I did something," Sirius said lamely, looking down.

"You did something?" James asked. "What did you do?"

"I... err... something that I should be ashamed of," said Sirius.

"... But you're not ashamed?" guessed James, and Sirius nodded. "So what did you do?"

"This is really hard for me to say," muttered Sirius.

"You want to write it down or something?"

"No... I'll just say it but please don't hate me or anything," Sirius pleaded.

"Like I could hate you," said James. "You're my best mate."

"Thanks."

"So... c'mon, tell me!"

"I..."

"Spit it out," laughed James. Sirius sighed.

"I sort of ch-cheated on Remus," Sirius said quietly, feeling tears forming in his eyes. He didn't dare look at James's face.

"Oh... well, that's not good," James commented. "And you're not ashamed of it?"

"Well I feel like the guiltiest person in the world because Remus is so amazing and he trusts me and I've gone and betrayed him," Sirius said. "I just... I don't know what to do, James."

"You really shouldn't have done that mate... you know how much Remus loves you."

"I know... but it sort of just... happened. I couldn't help it."

"I just can't believe you'd do that to him," said James, shaking his head. "That's completely out of order, Sirius."

"I know!" said Sirius angrily. "Do you think I don't know that? I see the look in his eyes when he's talking to me and when he looks at me and it kills me!"

"How many times have you done it?" asked James.

"Three times now," admitted Sirius shamefully, and James sighed.

"Three times? Why, Sirius? What's this other person got that Remus doesn't have?"

"I have no idea," said Sirius. "I... I really shouldn't enjoy it because it's so wrong but I can't help liking it."

"Who was it with?" asked James. Sirius sighed again. This part was going to be hard.

"Please now, don't think I'm a creep or anything," said Sirius cautiously.

"I already think you're a creep," James joked, ruffling his friends hair. "Who was it?"

"James... really... I.. err..."

"C'mon!"

"It was w-w-with... err.." Sirius closed his eyes and prayed that James would understand. "It was with R-Regulus."

There was a long, painfully awkward silence following the words Sirius had spoke. Sirius chanced a look up at James who was staring right back at him with cold eyes. "Do you hate me?" Sirius asked in a small voice.

"I don't hate you," James said. "But you know who will?"

"Remus," mumbled Sirius.

"Sirius, you cheated on your boyfriend – who by the way, is the kindest, sweetest, most loving person I know – with your own brother!"

"I know it sounds bad, but-"

"There is no 'but'!" shouted James. "What the hell were you thinking?"

"I wasn't thinking-"

"You never think, do you?"

"I'm sorry," muttered Sirius, looking back at his feet.

"Is it really me you should be apologizing to?" James asked. Sirius shook his head.

"I can't apologize to him," said Sirius. "I don't want him to know."

"He deserves to know, Sirius!"

"But I don't want to lose him," cried Sirius desperately. "Please don't tell him."

"I'm not going to tell him, since I already said I wouldn't," James said. "But I don't understand why you did it!"

"I... he was scared at home and w-we were just talking and h-h-he just kind of k-kissed me," stuttered Sirius. "And it was great."

"You should be repulsed. It's disgusting!"

"I couldn't figure out my thoughts..."

"Sirius," hissed James. "I suggest you stop thinking of Regulus and promise me nothing will ever happen between the two of you again."

"I can't promise that," said Sirius sadly. "It's like you promising me you'll never think of Evans again."

"Get over yourself! At least when I think of Evans, I'm thinking of a girl who's single and very much unrelated to me, and at least I'm not cheating on the love of my life with her because she is the love of my life! You on the other hand, are already in a perfectly good relationship with the love of your life and you're being such a fucking prick by cheating on him with your own bloody brother! Honestly Sirius, be thankful you have Remus... you're so lucky to have somebody who loves you with all of his heart, and you're just taking advantage and being a selfish bastard!"

"I know," Sirius mumbled almost silently.

"IF YOU KNOW, THEN WHY THE HELL ARE YOU DOING THAT TO HIM?"

"I don't know!" shouted Sirius, tears falling from his eyes. "I just don't know."

"Please stop," said James. "Do you realize how hurt he'll be when he finds out? And yes, he will find out if you don't stop immediately..."

"Not if we do it in secret," said Sirius.

"What sort of attitude is that? It's Ok to cheat on Remus if he doesn't know about it... is that what you believe?"

"Of course not... I didn't mean that," sighed Sirius. "I just don't think I can stop doing it."

"Give me one good reason why you can't stop going off and kissing your brother," James said, folding his arms and staring right into Sirius's eyes.

"B-because he makes me f-f-feel good," said Sirius.

"Doesn't Remus make you feel good?"

"Obviously he does! He makes me feel great, but I think Regulus makes me feel better."

"You're disgusting, Sirius," James spat. "C'mon, we need to go to Potions..."

"Yeah," mumbled Sirius, grabbing his bag and heading for the door. James put out a hand to stop him.

"I'm not happy with you at all, you know?" he said, and Sirius nodded. His cheeks were stained with tears and he couldn't look James in the eye.

"""""""""""""""

They left the classroom and made their way down to the dungeons in silence. When they reached the classroom, they met Peter and Remus by the door.

"Sirius!" said Remus, running towards him and hugging him. Sirius smiled and stroked his boyfriends hair. He looked at James and noticed the sadness in his face as he watched the two of them together. When Remus pulled away, he looked up into Sirius's face and frowned.

"Have you been crying?" he asked.

"No," said Sirius quickly. "Why would you say that?"

"You look like you've been crying," said Remus, touching Sirius's cheek. "You're not upset or anything, are you?"

"Of course not Rem," said Sirius, smiling. "It must have just been from the wind getting in my eyes during Quidditch."

"Are you sure?" Remus asked.

"Yeah, I'm sure. C'mon, let's go inside," he said, pulling Remus into the classroom. Remus, Sirius, James and Peter all shared a desk in the classroom, and Sirius could feel James's eyes on him throughout the duration of the lesson. Sirius sighed and looked at him.

"Have you got something to say?" he asked, teeth gritted.

"You know perfectly well I have something to say!"

"Fuck off... I thought you said you'd understand! Stop looking at me as if I'm some sort of creep!"

"Hey guys... err... what's going on?" asked Remus, looking from Sirius to James. Neither answered him, so he looked at Peter who shrugged.

"You're lucky I'm such a good friend," said James. "Otherwise I'd tell."

"Tell what?" asked Peter.

"SHUT UP PETER!" hissed Sirius.

"Hey, he was only curious," said Remus. "Siri... calm down!"

"I won't calm down!" shouted Sirius, shrugging Remus's hand off him. He stood up with his fists clenched by his side. "You're not a good friend!" he screamed at James, making other people in the class turn their heads to watch. "If you were a good friend you'd understand!"

"SIRIUS!" said Remus, pulling him back into his seat. "What's going on? What happened between the two of you?"

"None of your business," said Sirius angrily, getting up and storming out.

He walked as fast as his legs could carry him, his fists still clenched and his teeth gritted. How could James be so horrible? He'd confided in him, and yet James kept having a go at him! James was supposed to be the one who would understand! Sirius kicked the wall hard and let himself cry again, the tears rolling off his face relentlessly. He started climbing the stairs to get to the main school, his footsteps echoing off the stone walls loudly. Just as he was at the top step, he collided hard with someone, falling back down to the bottom of the stairs with a crash.

"Sirius!" shouted a voice. Sirius groaned. His head was throbbing and he wasn't sure he could sit up. The corridor was out of focus and he could hear a loud ringing in his ears. He heard footsteps around him, but he couldn't move.

"Take him to the hospital wing," he heard someone say, and he felt himself being lifted. He was sure he could see his friends in the crowd of people standing around, and he could see a number of teachers. There were a few Slytherins gathered around and he could hear them sniggering and laughing at him, but he didn't care. He just wanted to get to his bed so he could lie down and forget it all. Everything went black.

"""""""""""""""

When he awoke, he realized he was lying in the hospital wing as the room, and his friends faces came into focus. He saw Peter, smiling at him. He could see James who looked sick with worry, and he could see Remus – poor, poor Remus, who had tears in his eyes. Remus grabbed hold of Sirius's hand and sat on the chair next to his bed.

"Sirius?" he asked quietly. "Are you OK?"

"Mmm," replied Sirius. "I'm good."

"Oh thank god for that!" said Remus, flopping forwards so that he was half lying over Sirius's body. Sirius looked down at his boyfriend and rubbed his back soothingly. Remus looked up at him with teary eyes. "You fell down so far," he sobbed. "And you weren't answering us when we were talking to you and I was so worried."

"It's all right Rem," said Sirius. "I feel fine now."

"Good," said Remus, standing up and rubbing his eyes.

"I'm sorry, Sirius," said James, stepping forward and sitting on the edge of his bed. He leaned forwards and whispered in Sirius's ear: "I'm sorry I wasn't very nice to you. I understand that you can't help how you feel and I mean, if you really want to do that to Remus then I can't stop you."

"Thankyou James," Sirius said, smiling and pulling his friend into a heartfelt hug. This was all he needed; a little reassurance.

When his friends left, he felt himself falling asleep, this time much more happier than before. James understood, and that was all he could ask for.
