In the morning, Lily discovered that Sirius and Remus had also kissed Ali and Bella during the night, but she couldn't get any details about it.

'The rest of the school's coming back in two days.' said Ali.

Lily shuddered. 'Snape. Gross.'

'We have to do it.' said Ali. 'It's disgusting, but hey.'

'At least Malfoy and Avery wash their hair!'

Belle laughed. 'True. And Todd is a nicer name than Severus or Lucius.'

'Bells you're not falling for him are you?'

'God no. He's pure evil.'

********

James, Sirius and Remus thought the girls had forgotten about the bet with the Slytherins. Ok, they hoped. But they were wrong.

Ali moved first. She waited in an empty classroom, and when Malfoy walked past, she grabbed his arm and pulled him in, shutting the door.

'What the hell are you doing?' he demanded.

'Me? You're the one that drove me crazy all holidays.'

'I didn't see you all holidays. Anyway, I'm a Slytherin. I don't talk to Gryffindors.' He turned to leave.

'I know.' said Ali. Malfoy turned back, confused. Ali ran her finger down his cheek. 'But I always liked what was forbidden.' She walked out, and left to find Lily and Belle.

They were sitting in the library with the Marauders. Ali walked over and sat down. 'Hey, what are you doing in the library? I didn't think the Marauders even knew there was one at Hogwarts. Isn't it ruining your reputation?'

'Ali, everything we've done recently has been against our reputation.' said Sirius.

Lily saw Snape walk into the library, and into the rows of bookcases. 'Excuse me, I have to get a book.' She left, and went to where Snape was. She could see him, walked around the corner, and 'tripped.' Without thinking, he caught her, then saw who she was.

'Thanks.' she said, smiling at him. 'Good reflexes.'

'I guess. Mudblood, get out of my way. I have to-'

She silenced him by placing a finger on his lips. 'It's ok. You don't have to pretend to hate me. Nobody's around. You can to what ever you want.' She moved her finger, tracing a path down his neck, and his arm, to his fingertips. 'You know, we don't have to pretend anymore.' She traced a heart on his palm and then left. He stood there, speechless. She grabbed a random book, and went back to her friends. 'Your turn.' she muttered to Bella, who nodded.

Later that evening, Bell found Todd bullying a little kid, who ran away when Bella distracted Todd.

'What do you want?' he sneered.

'I want a lot of things.' she said, moving towards him. 'I want to bad.' she stepped towards him, and his back was against the wall. 'I want to do something I shouldn't do.' She stepped forward again and pressed her body into his. 'Be with someone I shouldn't be with.'

'We can't.' He whispered. 'You're a Gryffindor.'

'Do you always do things just because you're supposed to?'

'No.'

She reached up and whispered into is ear. 'Then there's nothing stopping us, is there? I'll see you around.' She walked off, flipping her hair.

*************

The next day, Ali found herself being pulled into a broom closet. She was shocked for a second, then she realised who it was, and she smiled.

'I was thinking about what you said.' whispered Malfoy.

'Wanting what you can't have?' Oh God this is disgusting she thought.

'There is that. But it will really piss Potter off.'

'Only if he knows about it.'

'I'll figure that out. For now, let's just…' He kissed her lips, and shoved his tongue in there.

'I have to get to charms.' said Ali. 'But we'll finish this later.' She opened the door, and walked to Charms.

*********

Damn. thought Snape, as he tried to concentrate on his potions essay, the one subject he could always do. Stupid Mudblood. She won't get out of my head.  Todd Avery was sitting next to him, and it looked like he was having trouble concentrating too.

Malfoy came in, looking triumphant. He walked over to Snape and Avery, and sat down. 'I' he said. 'Have the perfect way to piss off Potter.'

This got the two boys' attention. 'What is it?' asked Snape.

'I date his sister.' Malfoy grinned. 'He'll hate it.'

'She won't do it.' said Snape. 'Gryffindors hate us.'

'She will. Girls always want what they can't have.'

'You don't get all the fun.' said Avery. 'I want her friend-Bella or something.'

'You should probably learn her name.' said Malfoy, then he turned to Snape. 'You want one?'

'He was staring at that mudblood today-Lily Evans. I'll take her.' Maybe it'll get her out of my thoughts.

'God the Marauders will hate this.' Malfoy continued. 'I can't wait to see Potter's face…'

*******

The Marauders, Lily, Ali and Belle were walking to lunch, when Lucius Malfoy appeared in front of them.

'What do YOU want?' asked James, disgustedly.

'Not you. Your sister.'

'Stay away from Ali.'

'James.' said Ali. 'it's ok. Hi.' she said to Malfoy.

'Hey.' he said, and put an arm around her waist, kissed her, and she kissed him back.

'Damn she's fast.' Belle whispered to lily.

'This'll help us.' Lily whispered back.

The Marauders were looking at the couple with disgust.

'Didn't think you'd get away that fast did you?' said a voice from behind Lily and Bella. They turned to see Snape and Avery.

'You think we'd let him have all the fun?' whispered Snape in Lily's ear.

The Marauders were looking at them now, except for Sirius who couldn't keep his eyes off Ali. Avery took Bella's hand and walked back til they reached the wall.

'Familiar situation?' he said. She nodded, and they started the tonsil hockey championships.

James turned back to Lily and Snape, dreading what he'd see. You can guess what he saw.

Malfoy smirked at him. 'Hey Potter. Was that a fun little show for you?' He walked off with Ali. Bella and Avery, and Lily and Snape, were still 'busy'.

'Stop it!' shouted Sirius, and surprisingly, everybody stopped. 'You two are disgusting! If you and Ali continue to do that, we're not talking to you again. EVER.'

Lily and Bella looked at each other, and Lily said one of the hardest things she'd ever say. 'Have a nice life Sirius.'

Snape smirked, and led her away. Bella and Avery followed.

'Can you believe they'd do that?' wondered Peter. 'Don't they have a conscience?' The rest of the Marauders were silent.

For the next two weeks, they saw Lily, Ali and Bella in the company of the Slytherins more and more often. They still wouldn't admit it, but they were jealous. They hadn't talked to the girls since that day in the corridor.
