A/N: So one of the reviewers suggested I'd do a sequel and a prequel, so you'd guys would know how this thing between Lily and James started. I really liked that idea. And me, being the tease that I am, I give you: The Prequel! You'll have to wait a little more for the sequel, because my state of depression has suddenly lifted, and I seem to only write good stories when I'm depressed. Hence the terribleness of the following prequel. I apologize deeply.

(Now, I do realize Lily isn't as promiscuous as I make her out to be, but bear with me. We're talking about a 17 year old hormone driving teenage girl, in the 70's. Weren't those the 'swinging' days?)

"I need sex."

"That's quite the declaration," Alice chuckles, giving her best friend a strange look.

"Oh honestly, Alice," Lily sighs, slumping down on one of the couches in the corner of the Common Room. "It's been over five months. I'm dying here!"

"Then go find someone and stop complaining about it!" Alice replies, opening up her study books.

Lily looks around the Common Room, searching for her next pray. In front of the fire, the Marauders are lounging around, books splayed out in front of them, chattering around animatedly.

Sirius is the first one she notices, his slightly long hair elegantly covering his eyes.

He catches her eye from across the room and she holds his gaze. He raises a curious eyebrow at her.

She smiles seductively.

This can be dangerous.

"Hello, Evans."

She almost jumps a foot in the air when Sirius Black slides in the seat next to her, a haughty smirk playing on his lips.

"Black," She answers curtly. "Can I help you with something?"

"Actually, you can." He stops, his head between his hands, staring avidly at her. She pushes her plate away from her and holds his gaze just as intensely.

A few seats away, Potter is glaring a hole in Sirius' head.

"Your friend, Alice, told me quite an interesting thing last night, something about you looking for a shag buddy?"

She has to remember to kill Alice later.

She rolls her eyes. "And what's it to you, Black?"

He smirks. "Well, I think I might have just the guy for you."

"I assume you mean yourself?" She scoffs, taking a bite from her treacle pie.

"Well actually, I meant Prongs," He raises his eyebrows at her, and she almost chokes on her food.

"Prongs? You mean Potter?" She sneers. "That'll be a cold day in hell."

"I'm sure you'll find ways to keep warm," He retorts, winking raunchily at her.

She glares at him. "There's no way I'm sleeping with James Potter. He loves me, remember? What I'm looking for is purely physical."

"Don't flatter yourself, Evans. Who says he still loves you? He hasn't asked you out in over a year. Remember that?"

She does, as much as she hates to admit it.

"Think about it, alright? You won't regret it," He raises his eyebrows suggestively at her before sliding out of his seat and joining his Marauder friends.

James catches her eye and she feels her stomach drop a little.

This can be even more dangerous.

"Evening."

She looks up from her homework into the warm eyes of James Potter and there seems to be a thickness in the air around them, so thick it was almost tangible.

"Hello," She replies, slowly and steadily, putting her books away.

He gives her a tentative smile and takes the seat opposite her. "So I hear Sirius has been talking to you-"

"-Yeah he did-"

"-and I just wanted to tell you-"

"-it's quite alright, I didn't mind-"

"-it wasn't my idea, I swear-"

"-I actually liked the idea-"

"-and I hope he didn't offend – uh, what?"

She smiles shyly and tucks her hair behind her ears. "Well, I've been thinking about it, and well, I must be incredibly desperate for doing this…"

He frowns and gives her an offended look. "Um, thanks?"

She shakes her head and chuckles lightly. "No, I didn't mean it like that, I just … well, I don't know… I just, I think we have chemistry, don't you think? I mean, we could be good together."

He gives her a lopsided grin. "You think so?"

She shrugs and nods. "Well we'll never know if we don't try, right?"

His smile is so boyish and contagious she feels her stomach tightening uncomfortably.

This just got incredibly dangerous.

"Are you ready?"

She takes a deep breath and nods, following him up the stairs to his dorm.

"Where are your friends?" She asks and he says they've sneaked down to Hogsmeade. She's taken aback and questions him about it but he just waves her away, holding the door of his room open for her.

"After you," He smiles, and she feels trepidation building in her chest, and her palms are sweaty.

The room is exactly like hers and the familiarity of it eases her nerves.

"Are you worried?" He asks and she bites her lip and nods slightly. He smiles. "Don't be. I promise I won't bite. Unless you're into that shit, of course," He adds quickly and she laughs.

His casualness surprises her and she wonders briefly if he'd done this before, and if so, how many times.

"Make yourself comfortable," He gives her a smile before taking his shirt off and throwing it across the room.

She almost chokes on her own saliva.

Quidditch has done wonders to his body, and she can't help but stare at his toned chest.

"You've got a little bit of drool there," He quips, pointing at the corner of his own mouth and giving her a devilish smile. She throws a pillow at him and laughs, sticking out her tongue at him.

"We'll see who'll be drooling soon," She retorts, slowly and teasingly unbuttoning her shirt, from the bottom to the top, slowly revealing milky white and lightly freckled skin.

His grin is slowly sliding off his face, only traces of a smile left as she throws back her shirt and stands there in her black lacy bra. The contrast between the fairness of her skin and the black of her undergarment is amazing and her eyes are so bright and green and he can't look away from her face.

"You look…beautiful," He breathes and she smiles softly, the hairs on the back of her neck standing on end.

He approaches her slowly, letting his eyes roam freely and unashamedly across her chest. His fingers thread through her hair, lightly dancing across her neck and down her shoulders and she feels goosebumps on her arms.

She bites her lip and waits for his next move.

It doesn't seem so dangerous anymore.

"Still nervous?"

His lips dance on her neck and down her back, across her shoulder blades, his fingers lightly brushing her breasts. The only sound that comes out of her mouth was a breathy moan, and she closes her eyes, relishing the feel of him behind her, completely flush against her body, his hands roaming everywhere.

"You know this is just sex, right? Nothing more." Her voice quivers and she feels his smirk against her skin and she bites her lip to hold back her groan as he slides inside of her, his tongue licking her ear.

She can't seem to get herself to speak. Every thrust seems to hit just the right spot and she has never had a partner who knew her body so well.

His movements start to speed up and she feels it building up inside of her, the ultimate release, and he somehow feels it too, and he knows just how to keep her going.

No.

Not dangerous at all.

A/N: Reviews are always lovely. Just don't cuss me too much for being so evil.

Oh and the line:
"That'll be a cold day in hell."

"I'm sure you'll find ways to keep warm."

is based on a line from the fic 'the day chivalry curled up and died'. So all rights to that phrase go to the writer of that story, UnbirthdayGirl (you should really read the story, it's hilarious). I'm terrible, I know but I couldn't help it, I just fell in love with it.
