A/N: The obvious belongs to the queen. Sorry for the lack of updates, I've had serious writers block and, if I'm being honest, writing smut scares the shit out of me. But I'll do it for the sake of the story. Eventually. It'll be a process, so work with me people! Anyway, enjoy!

After that night when Lily joined him in bed, sleeping together became an unspoken routine. On nights when they had lots of homework, they slept in Lily's room. Why move when you were already there, right? On nights when they had Head whatever duties, either together or separately, they slept in James' room. Now I know what you're thinking, James didn't try anything funny. He had more respect for his girlfriend than to take advantage of her. However, he didn't know that Lily wouldn't mind being "taken advantage of" every once in a while…

Lily got Marlene, Mary, and Donna together one night and sat them down near the fireplace. They had a lot of catching up to do, and it was about time that Lily told her best girlfriends about her relationship with James.

"So there's something I need to tell you guys.." Lily started.

"Okay.." Mary said

"So James and I are, um well, you see, we've been dating since the end of sixth year.."

Silence.

After a minute of digesting this newfound information, Marlene spoke.

"Well, is he a good shag then?"

"WHAT?!" They all screamed, dissolving into a fit of laughter.

"HA I don't know Marlene! We've only snogged. I mean he touched my boobs once but that's it."

Donna snapped her fingers and tossed her hair,

"Damn gurl you best be gettin' on dat"

Seeing Donna get all sassy was something that never failed to make them laugh.

"No but seriously, Lil!" Mary said, "You guys live together. There's no reason why you shouldn't do something else!"

"HOLD IT!" Donna screamed suddenly, "You guys live together. Do you guys sleep in the same bed too?" When Lily nodded, the three girls screamed.

"What's stopping you then!?" Mary asked.

"What if I'm not good at it?" Lily answered quietly.

"Well practice makes perfect babe," Marlene said, shoving Lily with her shoulder playfully.

"I'll try something tonight, okay?"

Two out of three of the girls nodded, except Donna

"On one condition."

Lily looked at her friend curiously, wondering what she could be up to.

"We get to hear every single sexy detail. Deal?"

Lily nodded, "deal."

"So lads, I've been keeping something from you." James said, sitting with his friends inside the Shrieking Shack. It was time for Remus' monthly adventure, so they were hanging out before it got to dangerous to be around him in human form.

"If it's that you're shagging Lily we know, mate." Sirius said casually.

"I'm not shagging he- wait you knew?"

"You're shit at hiding stuff." Remus said, shrugging.

"Wait a minute." Peter finally said, "you mean you've been boyfriend/girlfriend for months now and haven't shagged?"

James shook his head.

"And why is this?" Sirius asked

"Cause she hasn't initiated anything. We've only snogged."

"You must be really sexually frustrated then" Sirius said, clapping his friend on the back, causing them all to start laughing.

"Let us know when something happens, yeah?" Remus asked.

"Sure" James replied.

James walked into the dorm from Head duties to find Lily curled up on the couch reading a magazine. Seeing her sitting there waiting for him made his heart skip a beat, so he went to sit down next to her.

"Hey love,"

"Hi!" She said, leaning to give him a quick kiss, "how were head duties and whatnot?"

"Boring without you to entertain me," He said teasingly, leaning in to give her another kiss. He expected it to be a short kiss, but when Lily threaded her fingers through his hair there was no going back. She bit his bottom lip slightly and an accidental moan escaped. She took that as the signal to deepen the kiss, not that James minded really. He kissed her back as passionately, their tongues dancing for dominance, and he took the opportunity to lean her slightly back on the couch, bringing his hands up to her breasts. To his delight, she wasn't wearing a bra, so James could feel her through the thin cotton shirt, which made him moan again. He started kneading his hands, causing Lily to start panting and, when he got the courage, he slipped his hands under her shirt and cupped her breasts, giving them a quick squeeze. She moaned again, wrapping her legs around his waist and pulling him in.

Lily could feel James' hardness right there and it was excruciating. Between his hands on her breasts and his erection right there, Lily's head wasn't exactly working properly. She rolled her hips, trying to feel him, causing them both to moan from the friction. James pulled back from kissing her and stared at her dead on,

"Do that again."

Lily leaned up to kiss him and rolled her hips once more, eliciting yet another moan from James who, at this moment, decided to stop kissing her. Hmph. Until, however, he moved his lips to her jaw, down her neck, across her collarbones, and to her breasts. He looked up, giving her a cheeky wink before taking one of her hardened tips into her mouth and sucking.

"Holy crap James!" Lily moaned, tugging on his hair as a signal to keep going, which he did, switching to her other breast and getting the same reaction. Wanting to give James something else to moan about, she rolled her hips yet again. To her delight, James flipped her over so she was straddling him, giving her better access and more opportunity to rub against him once again.

Moving his mouth from her breasts back to her lips, James didn't waste any time kissing her passionately once more. Lily rolled her hips and James didn't know how much more he could take. He pulled back, looking at his beautiful girlfriend, sitting on top of him, knowing she could feel him right there. He gave her a cheeky smile and rolled his hips, causing her to moan. Taking the words from before, she looked at him and said,

"Do that again."

He didn't waste any time obliging. He rolled his hips once more, the exact same time she decided to roll hers. The friction was insane and they both moaned.

"Again." She said simply and it took everything James had not to come right there and then. They rolled their hips together once more, the friction growing more and more, until neither of them could take it anymore.

Lily gasped, and James didn't entirely get what was going on until her eyes rolled back into her head. Then, watching her for a moment, James finally understood what happened.

Lily Evans just had an orgasm.

And that alone was enough to push James over the edge, coming hard and fast in his pants.

After Lily rode out her high, and after James rode out his, she got off of him and sat back down on the couch.

"Well, that was-" he started,

"Amazing." She finished, smiling at him.

"We should do that more often." He said, smiling back.

"Absolutely."

They stayed like that for a moment, staring at each other and smiling, until James cleared his throat and stood up.

"I'm gonna go shower, kind of dirty now." He said, giving Lily a quick kiss before heading off.

After a quick shower, he didn't need to take a long one after that, he threw on his PJ's and grabbed his book when his mirror started "ringing."

"JAMES FUCKING POTTER WHERE THE HELL ARE YOU?!" Sirius screamed

"shit." James mumbled, picking up the mirror to face a very angry Sirius.

"Yeah shit you asshole. Remus is about to turn and he needs us. Get your ass over here before I come after you, asshole." Sirius said, disappearing from the mirror.

He sighed, disappointed that he wouldn't get to snog Lily again, and walked out of his room and to hers. He knocked on the door,

"Yeah?"

Lily was now wearing super short shorts, an old tee shirt, her hair was tied into a messy bun, and James couldn't get over how gorgeous she looked. He literally had to shake the thoughts of him taking her then and there out of his head.

"I have to go, I'll be back in a few hours."

"Okay"

"Don't wait up, okay?" He asked.

"Mhm."

He turned to leave, then suddenly turned around, gave Lily a quick kiss, and ran off.

Lily smiled, closed the door, and went to sleep.

Not a bad night, not a bad night at all.

A/N: Thoughts? That was my first attempt at writing smut! Sorry if it was shit!
