So here's the second chapter of the story, hope you like it :)

Cherry lips, crystal skies

I could show you incredible things

Stolen kisses, pretty lies

You're the King, baby, I'm your Queen

Find out what you want

Be that girl for a month

Wait, the worst is yet to come, oh no

Marlene was staring at her textbook for half an hour now, praying for the lesson to be over. She'd have to ask Lily for help with it later. Now she just prayed for being invisible to Slughorn for just a couple of minutes more.

She was relieved when she could finally exit the classroom and walk to lunch where she was joined by James and the rest of his friends. When Black sat beside her, he eyed her plate and smirked.

"Cinnamon cake, McKinnon? I thought you had a thing for vanilla"

She send him a death glare "I don't like sticking to something for long, Black."

Sirius seemed to understand the meaning behind these words, but decided against replaying.

"James do you still want to study today? I was thinking about asking Lily for help, but I'm not sure if she has patrol tonight."

"Sure, Moony, you're in?" he looked from his plate and at his friend.

"I was going to help Peter, but we can both join."

"Oh my Merlin, guys, you're so boring. I'll have to find myself a greater entertainment than sitting covered in books that wrote people whose names are known only to people in this library."

"By 'greater entertainment' you mean snogging or shagging in a broom closet?" Remus smiled

"We'll see" He smirked.

"Marlene, what can you do with polyjuice potion?" James flipped the pages of his textbook with a knowing look.

"I've no idea James, what can you do?" Marlene sighed and put her head on the desk. The library was occupied by only a few people, the candle lights were making the space cozy and it made Marlene want to sleep.

"I don't know. Do you think Lily would?" He seemed worried, as if the perspective of her being better in potions suddenly scared him.

"Probably" Marlene raised her head and looked at him questionably "Why would you care? Lily was always a genius at potions."

"But I've always thought she studies for it all the time. And now I see she does a lot in this school. How much time does she actually study?" He messed his hair.

"Jamsie, dear I'm sure she's studying a lot anyway. But I'm happy to finally see you two no trying to bite your heads off. Well, you never did. But she has. Maybe you're not so bad after all."

"Well, if I want to prove that to her you need to become a potion's master. Get me a few textbooks, would you?"

"Sure" Marlene stood up and disappeared behind the bookshelves. She was taking a small book, when she felt a hand on her hip. She froze.

"Don't worry, love. It's just me."

"Aren't you supposed to be in a broom closet of some sort?"

"I've already picked myself a snog for tonight"

Marlene turned around quickly and felt his lips on hers. She pushed away with a groan. "The fuck, Black?"

"I thought I'd try to convince you vanilla isn't so bad, after all." He kissed her again, this time it would be harder for her to push away. She gave up fighting once she felt his tongue sliding into her mouth which she welcomed with another quiet groan. His kisses weren't soft, they were full of passion and hunger. If she was to be honest with herself she'd admit she liked this kisses a lot.

It was after their fourth make out session Marlene decided to stop it. It wasn't right. She wasn't that kind of girl. She had dated a lot of people in the past, but it was never the fooling-around-not-telling-anyone kind of thing. She didn't want to be another one of Sirius Black's snogs or shags. She wasn't an easy girl. Why was it hard for her to stop it? The only answer would be that she wanted it to happen, which was far from true. She never meant to fool around with James's best friend. Especially a friend with that reputation. First, James's would kill them both. Second, he'd make it look like a giant secret they've been keeping from him, he wouldn't let them do anything alone anymore. Third, Lily would be disappointed. She wouldn't admit it, but she wouldn't expect Marlene to behave like that. And fourth, Marlene never got that low to become a Sirius Black's chaser. Not in a lifetime.

And hour later she was exiting the broom closet one more time, cursing herself for being such an idiot. Whenever she tried to set things right he was bringing her closer, kissing her even more passionately, making her want to stay there forever. In these circumstances it was hard for her to think straight of anything, especially about ending this.

"I'll end it tomorrow" she promised herself, not even half believing it.

She was lying in bed when her friend Lily stormed into their dormitory after long patrol a few days later. She was clearly angry, so Marlene calmly closed her magazine and put it away, then looked at the red-head.

"That prat, James Potter! I already thought he started getting normal, and of course he showed he's still the same arrogant douche he has been always." She jumped to Marlene's bed sitting herself right next to the blonde. "We were supposed to patrol the corridors together today, but of course he must have had different plans, as he hadn't showed up. I went alone, as one does when one has to. He was with that slut Emmeline Vance. I don't care what are his relations with her, but I expect him to actually show up, as patrols should be his priorities. I'm sure he wouldn't dump a quidditch training like that. And of course he was shouting that it's Emmeline who made him help her with homework and stuff, which is just such a bullshit, I mean, you saw her boobs?"

"Lily, is it really still about the patrols?" Marlene tried to hide her smile.

"Of course, I was left alone! I don't usually like pulling Black from his shagging sessions, it's Potter's job."

"Did you have to do it?" Marlene should be surprised. They weren't intimate. That was to be expected. She knew she wasn't his only one. Right?

"Oh please, Black has a new bird every day. I can't believe these girls are actually okay with that." She shook her head "Well, whatever. Potter just proved to still be the same idiot as he used to be."

"Lily, you two have been getting on so well recently. Do you really think he hasn't changed in the slightest?" Lily looked at her if she was delusional.

"That's what I just told you." She confirmed.

"Lily, I was hoping you two were going in the right direction, and I'm holding onto that. Maybe you should think through what you really like in James" With that Marlene went to the bathroom to shower. She should expect Black to have girls. She shouldn't have thought they were exclusive. They weren't. And she had to make sure it all ended now.
