His lips were soft at first, exactly how she imagined them. He kissed her almost indulgently, like he was savouring her taste, committing her lips to memory. She felt herself sink into his lap, like the movement of his lips were lulling her. But as he kissed her softly, second after second, Lily felt something build up inside her- a deep longing for more. She moved in his lap slightly, rolling her hips forward so they slid neatly with his. A groan from James escaped into her mouth and she was a hundred percent certain that that exact sound was the undoing of her. She slipped her tongue into his mouth, threading her fingers into his messy locks with a grip that would normally be considered hurtful. In this scenario, James moaned again and his hands found purchase under her skirt and on her hips. The very touch of his large palms on her bare skin made Lily shiver with more need than she knew what to do with.

They kissed, tongues sliding against one another, teeth biting playfully between lips, until Lily felt her bones ache and her skin so sensitised she thought her nerves had gone numb. With a sound that Lily had never heard come from her mouth, James murmured a simple 'fuck' and moved his mouth to her jaw, nipping and sucking as Lily wriggled in his lap.

This kiss was completely unexpected. Well, not the kiss itself, Lily knew it was coming but the very essence of the kiss was unexpected. The way it made her feel. She expected it to be good, with James confidence and self-esteem, she had assumed he was a good kisser. But it was the way they fit together that shocked her, the rhythm of their kisses, the movement of their bodies, it was chemistry. She knew they had chemistry, but in the way that they bantered and the way their conversation flowed easily. She did not expect their chemistry to also manifest physically as well.

As James peppered kisses on her jaw and down her throat, Lily gasped and moaned. The sounds seemed to spur James on and illicit sounds of his own. She couldn't believe she was making James Potter make sounds like that. Her body wanted more, needed more, so she started to roll her hips closer to his. Noticing the hardness in his trousers, she rolled her body against the size. She had never explicitly kissed someone this way before, her knickers the only thing covering her center as she grinded against his length.

James swore again and cupped Lily's face as she grinded into him.

"Fucking hell Lily" he breathed heavily, the words so husky that Lily couldn't help but bite her lip in response. His pupils were blown and all Lily could see was black. He looked at her with such desire that it made Lily moan and wiggle against him more.

"I thought our first kiss would be sweet. Turns out it's anything but" he murmured into her lips before taking them again and kissing her hard and fast.

His hands started to wander, his warm palms pressing against her back and sliding to her tummy. It was like he was stirring up an impatient monster inside of her stomach with his rubbing. Her breath quickened and James took that as a sign to move his hands lower, tracing his fingers along the length of her knickers, making her shiver audibly. He smiled in his kisses as she shivered and she bit his lip in jest. His following laugh made her giggle too, like bubbles of happiness had made their way up her throat.

He stopped their passionate kissing to look her in the eyes, a silent question to continue. She looked at his dark hazel eyes and back to his swollen lips, nodded shallowly and then pushed her hands back into his hair and kissed him deeply.

She felt his replying moan reverberate on her own chest, which made her very aware of his broad shoulders and chest. She let her hands wander downwards, to the shape and curves of his muscular shoulders, to his biceps and then to his chest. He was skinny but she could feel the muscles shaped from Quidditch. She was very determined to see him without a shirt on again.

As she slid her own hands under his school shirt, James' hands traced the underside of her knickers.

She had hooked up with two boys previously over the summer, but nothing had been as teasing and as drawn out as this moment with James. With the other boys she had always felt aware of her every movement, unsure about what she was doing, aware that the way they touched her elicited only a small amount of pleasure. She assumed she was just not the type of girl to see stars and have her legs turn to jelly when with a boy. James threw this theory straight out of the window.

Just the briefest touch of the top of his fingers brushing against her bare center made her see stars.

She moaned into his mouth, causing James to chuckle. She probably would have chided him for seeing humour in her eagerness but it just felt right for him to laugh, as if he was laughing at how insane and enjoyable this situation was for him, not just her.

She smiled with her eyes closed, kissing him softly as he inched his fingers under her knickers.

"Lily" he breathed heavily, whispering her name in awe.

"Mmm?' She started to pepper kisses around his jaw, her lips brushing against his five o'clock shadow.

"You're dripping," he whispered.

Lily quickly thought she should probably be embarrassed by her body's reaction to them kissing but the way James said the words, instead it made her proud. He was completely in awe and she thought probably in shock too.

"Please" she begged, returning her lips to his.

But just before James could even begin to spin her into a spiral of intense pleasure, a loud banging echoed in the room.

The two of them swiveled their heads towards the entrance to their common room, eyes wide and bodies tense.

"Prongs! We know you're in there" Sirius' sharp accent called out.

Lily instantly leaped off James's lap, hands brushing her hair straight, wiggling her skirt back into line. She looked at James in shock, the same expression mirrored back.

"I need to go to the bathroom" she rushed, jogging towards the bathroom just off of the common room.

James also straightened himself out before calling out to his best mate. He huffed with annoyance, his best friend truly had the worst timing. He turned around, resting his arms on the back of the sofa.

Sirius Black and Remus Lupin strolled into the room, Sirius grinning and Remus pointedly looking for Lily.

"Dude, you need to get your hair under control" Sirius chastised, ruffling James' already messy hair. James quickly smoothed down his hair worriedly, his eyes darting to the bathroom quickly before settling on Remus. Who had made himself comfortable on James' desk chair behind the sofa. He raised his eyebrows humorously, and James quickly worried that Remus' just knew what had just happened. Sirius sat on Lily's desk, something he knew what grind Lily's gears and propped his feet up on her chair.

"Where's Pete?" James asked.

"Went to the kitchens to get us some snacks" Remus replied, his eyes still looking around the room.

"Oi, where's Evans?"

"I'm right here, Black, '' her voice comes from behind James, who is still leaning on the back of the couch, arms slung over the back and chin resting on the hard cushion. He has to will his body not to turn at the sound of her voice, he doesn't want to give Remus anymore ammunition than it already looks like he has. Instead he watched Remus raise his eyebrows at Lily and then smile at her.

"Hello Lily"

"Hey Remus, what are you guys up to?"

He felt her settle on the couch next to him, and he turned to finally look at her. She's propped her back up on the armchair of the leather couch, her legs spread out, her toes nearly touching his knees. She twists her head to look over the back of the couch so she can talk to Remus easily.

"Mind if we take over your common room? James said we could work on something here" Remus asked politely, causing Sirius to scoff.

"We don't need her permission, its James space as much as hers"

Everyone ignores Sirius and Sirius huffs as Lily replies that it's ok. As Remus chides Sirius for shuffling through Lily's homework, James takes the opportunity to look at her properly.

She's fixed her hair back into a ponytail, her cheeks are still flushed and her lips look a little swollen but otherwise she looks fine, more than fine he thinks, she looks gorgeous.

She smiled knowingly at him, making his stomach flip. He watches as she quickly looks at his mates and then she does something that makes him nearly swallow his tongue. She pulls her skirt up her thigh slowly and all James can focus on is the sparseness of her bare thigh and then her….

She's not wearing knickers.

His hands grip heavily on the back of the sofa, his dick throbbing in his pants, his throat dry and his blood pulsating. He raises an eyebrow at this wonderful fire sprite and shakes his head with a smirk. She smiles devilishly before turning her gaze back to his friends and fixing her skirt.

He tries to listen to his mates talk about their days, but really all he can think about is Lily on his lap, no knickers on.

They can all probably tell he's not listening, he's not exactly contributing to the conversation but before he can finally say something to Remus' comment on the detention they handed out earlier this afternoon to a third year hexing a first year, Peter tumbles through the door, arms clad with sweets and biscuits.

"Wormy, finally!" Sirius cries dramatically, grabbing a sleeve of bourbon biscuits from his arms.

James knows that he won't be able to easily get rid of his friends now, with food, a warm fire and the promise of more prank planning, they would probably be here all night.

He can't wait that long, so he thinks strategically.

"Evans, don't we still have to schedule next week's rounds?" pointedly giving her a look.

Lily narrows his eyes but she nods understandingly.

"Right, yeah. Can we do that before you start whatever mischief planning you're concocting?" She grins at Remus who smiles back, his blue eyes watching the two of them.

He tries not to think about Remus' knowingly looks and instead jumps up off the couch.

"Alright, Evans lets get this over and done with" he grins cheekily at her and she shakes her head.

"It will take ten minutes," she teases.

James narrows his eyes.

"Maybe a little longer…" he presses eagerly.

"Only if you give me trouble" she teases back.

The two of them don't notice the way Sirius stares quizzingly at them and the way Remus smirks. Peter's too busy sorting his snacks into neat rows to care.

Instead James follows Lily towards her room. She shuts her door and quickly casts a silence and locking charm, he grins as she mumbles the words.

"Ten minutes?" he teases.

She turns around to face him and strides slowly towards him. He walks backwards, his eyes too busy drinking in the image of Lily stalking him, her long legs, her green eyes drinking him in also. His legs hit the back of her bed and he perches himself on the edge.

"You did a really good job at warming me up Potter, I don't think I'm gonna need long" she murmurs slowly.

His blood sings in a way he had never experienced before. Lily Evans does something to him. He still doesn't know what it is, but he has always been in awe of this woman, and watching her drink him in, her eyes dark with lust, he truly thinks he's dreaming.

Lily needs him.

He's on her bed, watching her walk towards him. His hazel eyes wide with shock.

She couldn't quite believe how much nerve she had taking off her knickers in the bathroom and showing him so brazenly in the common room. But James Potter makes her want to do things like that. Act primal, needy, wanton.

She climbs onto his lap with ease, her bare center hot against his trousers.

"Please?" she asks sweetly.

She doesn't have to explain what she wants, as seconds later James groans and drags his hands up her bare thigh, his fingers searching for her clit. Pressing, rubbing, circling, Lily wriggles in his lap and sighs heavily, all pent up frustrating leaking out of her.

She tries to kiss him, but her brain fires neurons left, right and center and she just can't concentrate on returning his wet kisses. Instead she rests her head on his shoulder, her breathing heavily panting in his ear. James uses one hand to pop up her top two buttons of her blouse, push away the material of the shoulder to lick and suck the delicate skin on her collarbone and neck.

She doesn't realise her repetition of his name until he chuckles and swears with pleasure. She shuts herself up by leaning back and biting his lip, causing James to swear once again.

"You swear a lot," Lily absently comments between pants.

He moves his hand away from her at this comment and Lily, who was on the very edge of what she thought was an orgasm, swears.

"So do you" he grins cheekily and Lily bit down on his shoulder. The material of his shirt wet beneath her mouth.

"I want this off," she says, gesturing to his shirt. He quickly pulls away from her body, ripping his shirt off his torso and scooping Lily back into his arms.

She leers at him indulgently, as he returns his hands to her thighs. She looked at him expectantly, hoping he would return his fingers back to her sweet spot. He smirks arrogantly, making Lily narrow her eyes. He laughs and returns his hands back between her legs, making Lily moan lowly and James to smile knowingly.

Before James can say something conceited, she attaches her lips to his shoulder, sucking harder than she had before. The build up in her stomach makes her impatient.

James scolds her but Lily ignores him, instead sucking and leaving blossoming red marks on his chest. Not long after leaving her pretty artwork on his bare chest, Lily feels the rise of an orgasm breaching. Goosebumps erupting over her skin, and her stomach clenching in anticipation.

"James, I'm close" she sighs.

"Fuck Lily, please"

She would later look back at this, and realise that having a boy beg for her to come was probably not normal. That his pleasure in getting her off, was enough for him.

Her body convulses, her center clenching and all she can do is close her eyes and open her mouth as the orgasm ripples through her.

She keeps her eyes closed after her orgasm, shock accompanying the pleasure.

"Lily?"

She opens her eyes to find James looking concerned. She leans forward and kisses him sweetly.

"You ok?" he asked with a small smile.

"Perfect" she sighed.

"Um, can I borrow your wand?" he asked bashfully.

Lily immediately leans over to grab her wand from where she throws it onto her bed. She looks at him curiously as she gives it to him.

"You um- weren't the only one to come" he explains.

Lily slowly moves off his lap and sits beside him, brushing her skirt down and suddenly realising how wet she still is. She hears James mutter a cleaning spell and her cheeks warm.

She had made him come just by coming herself.

She can't quite believe what had just happened.

"You sure you're ok? Was that too fast?" James asks, a soft concern echoes in his tone.

She looks at him properly, her thoughts finally coming back to order from their jumbled mess.

"Yeah, just out of breath I guess" she suggests, smiling at him.

He smiles back and pulls her into his side, letting her rest her head on his shoulder. She had always wanted this side of James, the ease and comfortability that he showed with his friends. It felt right and real.

"That's um never happened before...with a guy" she explains, unsure why she felt the need to explain that little tidbit to him.

James was quiet for a minute and panic quickly rippled through her body.

"You've never orgasmed?"

She was sure her face was bright red.

"I have - by myself" she buries her face in her hands now, too embarrassed and instantly regretting saying something about it "- No one has ever been able to...you know. Not that there were loads of guys, only a few" She was rambling now, so she quickly shut her mouth and shook her head.

"You are really bad for my ego, Evans" he chuckles.

He pulled her back into his arms and she feels him kiss the top of her head.

"I just hope that that means you felt comfortable enough with me to let go" he explains.

Her heart warmed.

"12 minutes" she murmurs.

James laughs, a soft familiar sound.

She can't help but smile at the situation. Tucked up on her bed, hiding from his friends. She likes having James to herself, but she knows this is meant to be fun, so she peels herself away from James' warmth and stands in front of him. Holding out her hands to him, he looks up and grabs them softly. She heaves him to his feet.

"You better go back to your mates," she smirks.

"If you decide to not wear knickers in the future, Evans. I'm definitely not going to complain" he smirks before unexpectedly, pulling her into her arms and giving her a long and deep kiss.

The kiss relaxes her, makes her bones feel warm and her muscles feel like jelly.

She doesn't hear him leave, she's still too busy trying to sort out her jumbled thoughts.
