A/N- I decided to tweek the stroy a little because I didn't like the way I had it written at this point. I hope you all like it.

Riley was lying on Sirius's stomach, their sheet sprawled across their waits. Sirius had his arm around her and their breathing was in perfect rhythm. James just stood shocked at the foot of the bed, his breathing and heart rate increasing.

"James, what is-ohhhh boy." Remus said seeing Sirius and Riley.

"I thought he came back with Rach." James yelled, "not my sister." James got really close to Sirius and smacked him a few times across his face and head.

"What the fuck? Who the hell?" Sirius said groggily. He opened his eyes finally seeing a pissed off James, a slightly amused Remus and felt the warmth from Riley's body and realization dawned on him, "James, let me explain." Sirius said desperately. Sirius carefully slide out from under Riley and put on a pair of boxers before he led James and Remus to the bathroom.

"What the hell were you thinking?" James asked, "Please tell me you were drunk."

"Yeah" Sirius said shyly.

"and was she?"

"Yeah."

"So you took advantage of her?' James yelled.

Sirius was surprised by his response, "No."

James ran his hand through his hair and started to pace the bathroom, "Sirius of all the girls you could have chosen, you chose her and went behind my back." James yelled.

"I'm sorry." Sirius said, "but you can't control these things."

"Yes you can. You keep it in your pants."

Sirius was trying his best not to lose his temper but James was being unreasonable and hypocritical, "James don't even go there. You have no case."

James took a deep breath, "Okay, now that your awake you can get rid of her, its only a one night stand." He paused for a second, "and none of us will tell Rachel."

Sirius sighed, "James you're not even listening."

"Stop." Riley said softly but grabbed the boys' attention. She was standing in the bathroom doorway draped in Sirius's sheet

"You." James growled rounding on his sister, "Do you like ruining everyone's lives." Riley looked hurt as James continued to yell at her. Riley dropped her eyes to the floor like a scared child being reprimanded by a parent, "He had a great relationship but did you care? All you care about is yourself!"

"This isn't the first time." Sirius cried out and Riley's eyes darted from the floor to him.

"What?" James asked dangerously.

Sirius was glad that he took James's attention off Riley but was afraid James might to something rash, "This isn't the first time." He repeated calmly, "We've been sleeping together for a while now."

"I'm sorry." Riley said trying to hold back her tears, "For all of this. I don't want you two fighting with each other. Please just stop." Riley grabbed her clothes and left for her dorm.

"You're an ass." Sirius said to James.

Slytherin ended up winning the match and a hostel air filled the great hall during lunch. James and Sirius stayed away from each other, trying to work off their anger towards each other. Sirius walked over to Rachel and quietly asked her if he could have a word.

"Normally, I wouldn't mind being in the Great Hall but I have some respect for you." He said while they sat on the marble stairs in the entrance hall, "I'm sorry but I want to break it off." She started crying, which never happened before usually he just got slapped or insulted, "uhh…c'mon now. You had to see we weren't working. Uhh…please stop crying."

"I'm s-s-sorry." She said trying to stop, "I'm j-just g-gonna go." She stood up and ran up the stairs towards her house. Sirius heaved himself up and ran his hand through his hair.

'Well that went well' Riley thought to herself. She just broke up with Scott. There was no way she could continue to date him, especially after last night. Riley couldn't understand why last night with Sirius affected her so much; she had been with him many times before. Riley looked out across the quidditch pitch, after she ended it with Scott she went to the Pitch to be alone. Riley decided that James was right and she had to stay away from Sirius.

It took the whole weekend for James and Sirius to start talking again and for Sirius to actually find Riley. Their History of Magic professor lectured like someone was paying attention. Sirius got up from his seat and took the empty one next to Riley.

"Hey." He said when she didn't acknowledge him, "Why did you break up with Scott?"

"Why did you break up with Rachel?" The bell rang and Riley didn't wait for Sirius's answer, she just took off. Sirius wasn't able to catch up with her until the portrait hole.

"I think you know why." He answered her.

"But why? Look what happened when people found out." Riley said, "Its not worth it." She took the stairs to the girls' dorms two at a time. Sirius felt his heart break more and more with each step she took.

A newly single Sirius met a group of girls following him everywhere. Sirius sat in the common room, not listening to a word the busty blonde was saying to him. The blonde took that as a sign to start grouping him and kissing his neck but Sirius didn't even respond to her. The life in Sirius's eyes was gone, the little hop in his step was gone, and he was like a zombie. His life consisted of going to class, skipping lunch, going to afternoon classes, taking a few bites of dinner and they going up the astronomy tower and drinking a bottle of firewhiskey. In front of James and Remus he put on a fake face and was his old self in front of them

Riley kept to herself like normal. She did, however, have a new following; any girl that was good enough for the Sirius Black, no matter how strange she is, is good enough for the guys. Outside the potions classroom, a tall-dark haired Slytherin stood over her while she stood against the wall waiting for potions to start. Riley nodded her head every once in a while to give the guy the elusion that she was listening. Just before class was about to start the marauders made their way down the stairs. Sirius caught Riley's eye and she couldn't look away as much as she wanted to. Her heart skipped a beat and Sirius held his breath. Neither of them wanted to end the glance. Riley would never admit to Sirius or anyone that she wanted to be with him and everything she ever said about hating him and him using her was a lie. Just as Sirius thought everything was going to be alright, Riley tore her eyes away from him.
