…..

Sirius Black couldn't remember ever having been in a better mood. He felt like he was on top of the world and nothing could bring his spirits down. Until he entered the library. He was looking for his girlfriend. His girlfriend. He still couldn't believe it.

After nearly giving up on finding her, he decided to check the back corner of the library, where no one ever went because all of the books in that section happened to be bloody boring. As he peeked around a bookshelf, he saw her and smiled. He didn't even consciously do it, the smile just appeared on his face naturally when he looked at her.

Then he saw who she was sitting next to. Severus Snape was bent over his essay, scribbling away madly, while Luna sat beside him, leaning back in her chair reading a textbook. Neither had noticed Sirius yet. "Sev?" she asked casually.

"Hmm?"

"You're good with potions. What is this mumbo-jumbo about dragon's blood?"

Severus opened his mouth to answer her, but before he could, he found himself slammed forcefully into the wall behind him. Luna leapt to her, pulled out her wand, and spun round to face the person who had attacked her friend.

Sirius Black stood with his wand at the ready and a snarl on his face as he glared at Snape. "Sirius!" she gasped, "Put your wand away this instant!"

"What are you doing with her?" Sirius completely ignored her and growled threateningly at the scrawny Slytherin.

"Studying, Black," the boy replied smoothly, "she asked for assistance with Potions, and I-"

"Well from now on," snapped Sirius angrily, "she can ask me any questions she has about Potions because I'm her boyfriend!"

A smirk played on the edges of Severus's lips, "Well well well, Black, you're not jealous, are you? That you found your girlfriend studying in a dark secluded corner of the library with a Slytherin?"

Sirius made a swift movement with his wand, but before the spell was cast, Luna took hold of his arm. "Be nice," she was speaking to both of them, sounding like she was addressing children, "Sirius, love, Severus is just my friend. And Severus, shame on you for baiting Sirius that way! You were just helping me with Potions."

"Be that as it may," said Severus conversationally, "I think we're done here for the evening. If you would be so kind as to remove the spell that has me pinned to this wall, I'll be on my way back to my common room."

Sirius looked mutinously at the boy in front of him. If anyone but Luna had asked him to be nice to Severus, he would have cursed them into oblivion. But because it was Luna who was tugging impatiently at his elbow, he snapped his wand forward, releasing the Binding Spell on his sworn enemy. Severus Snape brushed off his robes lazily, collected his books, and left without another word.

"Sirius," said Luna quietly as she brought a hand up to brush hair out of his face, "you weren't really jealous, were you?"

"Maybe I was," his voice was rough. Luna flinched inwardly. She had known that her friendship with Severus would bother her boyfriend, but she had hoped it wouldn't bother him this much.

"He's my friend," she whispered.

"Why?" Sirius rounded on her. Anger radiated from him, but Luna didn't care.

"Because he's nice and lonely and he needs a friend!"

Sirius snorted, "That's just about the most idiotic thing I've ever heard. He's Dark, Luna. He practices Dark Magic and is without a doubt well on his way to becoming a fucking Death Eater. Is that the kind of friend you want?"

"You don't know anything about him," she said dismissively, "you've only assumed those things."

"He's always been following us around. Trying to get us expelled. He hates us, Lu-Lu. Especially James."

Luna's hand, which was still on his face, traveled down his jaw slowly. She knew that his hatred toward Snape would never go away. She knew that they would never be friends, nor probably ever be able to even tolerate each other. Therefore, if she couldn't win this argument, she would simply distract Sirius from it. Her voice was husky when she asked, "How long have we been dating now?"

"Three days," he answered immediately.

"Do you think that's too soon to get hot and heavy in the library?"

She batted her long eyelashes and gazed up at him with an innocent expression. His grey eyes were dark with lust at her words. "No," he said simply.

"You wouldn't think badly of me if I…" she tugged on his loose Gryffindor tie, "pulled you down onto this table and…," she stretched up onto the tips of her toes and pulled his head down so she could whisper in his ear, "had my wicked, wicked way with you?"

In response, Sirius's hands gripped her waist, pulled her hard against him and he turned his head to nip at her exposed neck. She sighed, relaxing into his body. Nobody had ever made her feel this way before. Sirius lifted her effortlessly and she slid her legs around him as he spun their bodies around to press her into the bookshelf.

His hand slid to the hem of her shirt and she gasped when she felt his cool fingers on the bare skin of her warm stomach. A deep growl of approval vibrated through his chest and Luna felt it against her. Not to be outdone, she tugged his white button-up shirt from his pants, griped the hem with both hands and tore it open, buttons flying in all directions. Sirius's eyes widened at her daring nerve but she just smirked up at him.

He didn't think he had ever seen something so hot in his life. He removed his hands from her sides and put them on the bookshelf, on either side of her head. Luna let her palms glide down his deliciously sculpted chest, his flat stomach, and back up, all the while her eyes followed the path her hands made and she unconsciously bit her bottom lip in a way that made Sirius moan and press his hardened length against her center.

The only things supporting her were the bookshelf against her back and her legs which were wrapped around the gorgeous boy in front of her. When she felt him press himself into her sex, she arched her back, pressing her clothed breasts against his naked chest. Trying to be more considerate with her clothing than she was with his, Sirius was carefully undoing the buttons of her uniform shirt, tugging it free of her skirt.

When he undid the third button, her shirt pulled open enough that her pink lacey bra was entirely revealed. The tops of her cream coloured breasts were begging for Sirius to taste them. He nipped, kissed, and licked his way from her neck down to the valley between her breasts. Luna let out a soft cry of pleasure when he bit just hard enough that she knew she would have a love bite there.

Her breath was coming in pants when she found her voice long enough to ask, "Are you really going to fuck me for our first time in the library, Black?"

Sirius chuckled darkly, dropping his head to let his forehead rest against hers as he fought to catch his breath. Feeling her chest heaving against his, knowing that he was causing these reactions in her, made Sirius have to curl his hands into fists to keep from touching her. Without meaning to, he pressed his erection against her again and was rewarded with an involuntary whimper from her lips.

"You don't like that, do you, love?" he teased, experimentally repeating the movement.

Prepared for it this time, she bit her lip to keep from whimpering and blushed scarlet when a moan escaped her instead. She had never felt this way before, and he had barely touched her! Her half-lidded eyes rolled back into her head as she raked her nails down his back, under his shirt. Vaguely her mind wondered why he was still wearing a shirt. When she reached up to slide the shirt off of his shoulders, Sirius caught her wrists in his hand and pinned them above her head.

"Are you always this dominating? I'm not one to be overly submissive, you know," she told him breathily.

Sirius grinned, "I was actually trying to stop you."

"What?" Luna couldn't help her cry of outrage. "Why?"

"Because you were right. I don't want to 'fuck you for our first time in the library' as you so eloquently put it," Luna glowered as he ran his free hand through her hair.

"Not even if I beg?" she pouted, grinding her hips against him. His head fell back in pleasure for a moment before he regained his composure and shook his head at her with pursed lips.

Before she could put up too much of a fight, Sirius stepped back, letting Luna drop down to her small 5'1 height, and stood with a good two feet of distance between them. "We should get back to the common room," he said tersely.

"You're a tease, Sirius Black," Luna scolded.

Sirius grinned devilishly as he pulled her into his arms, kissed her roughly and whispered, "I never claimed to be a saint, love."

…..

When the two arrived back in Gryffindor Tower hand in hand it was to find Mary pacing worriedly in front of the fireplace. James rolled his eyes at Sirius in an exasperated way, as if Mary's pacing was bothering him. "Remus is in the hospital wing!" she said shrilly to Luna and Sirius the moment she saw them.

"What happened?" asked Luna anxiously as she released her boyfriend's hand and went to her friend.

"I don't know. He's been looking a bit pale, I mentioned it to him yesterday, but he said he was fine. Then, this evening, he said he had to go see Madam Pomfrey and rushed off. I went to the hospital wing to visit him, but Madam Pomfrey refused to let me see him! She said he was ill and needed rest," Mary was practically in tears.

Luna glanced out the window. Just above a swiftly moving cloud was the round full moon. She sighed and wrapped a comforting arm around Mary's shoulders. "I am sure he is fine. Madam Pomfrey knows what she is doing. He probably just has a bad cold."

Mary gave her a weak smile, "Thanks, Luna," the two girls hugged.

"Padfoot," snapped James as he got to his feet suddenly, "Wormtail," he added bracingly, "I think it's time we retire for the evening, mates. If we want to rise early tomorrow morning to grace the inhabitants of Hogwarts with our presence, we should get plenty of rest."

"Godric knows you need all the beauty rest you can get, Peter," said Sirius teasingly. Peter made a face but then laughed good naturedly. Sirius turned to Luna. "Goodnight," he said lightly, thinking mischievously about the ruined shirt his robes were hiding.

"Goodnight yourself, Black," Luna purred sensually as she snuggled up to him for a quick but passionate goodnight kiss.

James fisted his hand into the back of Sirius's robes and yanked him away from the girl saying, "Come on, Padfoot, best get you to bed before you get carried away." The three boys disappeared up the staircase.

Luna glanced around the common room in a bored way wondering what to do with herself now. The night was still young. She slowly dragged her book bag up the stairs and tossed it onto her four-poster bed. Should she write in her journal? No, she felt like she couldn't sit still. She wanted to go for a walk but didn't really have a destination in mind.

Would the shops of Hogsmeade be open now? Perhaps getting a small gift for Sirius would be a good idea and hopefully soften him up just a bit to the idea that she was friends with Severus Snape. But what would he want from Hogsmeade? Luna's eyes lit up as an idea struck her. She would go to Hogsmeade and then Apparate into muggle London to buy him a gift. Shops in London were open to all hours of the night and she was sure he would appreciate a muggle gift than a wizard one. He was almost as bad as her Grandad Arthur with his obsession for all things muggle.

With a girly giggle that sounded nothing like herself, she drew a warm cloak around her shoulders and skipped down the dormitory stairs. With a wave to her friends, she exited the portrait hole humming merrily to herself.

…

After James had unceremoniously dragged Peter and Sirius from the common room, they began to get ready for the night ahead of them. Every night of the full moon they snuck out to meet Remus in the Shrieking Shack. Some nights they explored the castle grounds, some nights they explored the village, others they stayed in the shack. Each time it was an adventure.

"Mate," said James as Sirius shrugged out of his robes, "what happened to your shirt?"

"Luna," said Sirius with a big grin. "In the library," he added, "she was so anxious to get it off of me she couldn't be bothered to pause long enough to undo the buttons. She just tore them off," he gestured to his open shirt.

James made a 'tsk' sound. "Please don't tell me that you shagged her in the library. First of all, for as much as you claim to like the witch that wouldn't exactly be an ideal place to have sex with her for the first time. Second of all, I would be a bit worried about you if you just gave your virginity to someone you've been dating for three days. Thirdly, that would be a bit skanky of her, don't you think?"

"James," growled Sirius, "did you really have to play the 'virginity' card? She doesn't know…that…yet," his grin had slipped quickly into a frown. Nobody at school knew his secret aside from his three best friends. James, Remus, and Peter, knew that Sirius was a virgin. Even Peter had sex before, even if it was because James had helped him out with that.

Sirius wasn't a virgin because of a lack of opportunities. As a matter of fact, he had made sure that several people caught him in broom closets with girls. He and James were the two most desired boys at Hogwarts and the girls he was caught snogging usually told anyone who would listen that he had slept with them and he didn't discourage the rumors.

Remus was the only other Marauder who was still a virgin. This was because of his condition. He respected women too much to have a fling or a one-night stand but was too afraid to commit to a relationship because he was a werewolf. Therefore he kept to himself and didn't give in to any of his lustful urges. Sirius wondered vaguely how long that would last now that he was in a relationship with Mary MacDonald.

James had had a few girls. Sirius knew this and had on one occasion entered the dormitory to hear it for himself. "I just don't understand it," said James in exasperation as he fastened his cloak, "why would that be something that was so important to you?"

"I don't know," Sirius answered honestly.

"Afraid you'll be rubbish at it?" James teased.

Sirius scowled, "No chance of that, mate."

"Come on," whined Peter, "We can tease Sirius about his lack of sexual experience later." Between one moment and the next, Peter had transformed. Being seventeen years old only had one disadvantage that James Potter could think of; they could no longer all fit comfortably under the Cloak of Invisibility. Peter transformed into a rat, letting Sirius scoop him up to save room under the Cloak. James gave them a cocky smirk before throwing the Cloak over the three of them and they made their way to the Whomping Willow.

….

Luna giggled gleefully as she made her way to Hogsmeade. She used a secret passage to get out of the castle then took the main road from the castle to the small village. It was very similar to Hogsmeade in her day, except Zonkos was there. Zonkos had eventually been bought out by her Uncle George.

With a shake of her head she shivered and pulled her emerald green cloak more securely around her shoulders. It was almost Halloween and the air was chilly. She was almost to Hogsmeade now and glad of it. Although she would never admit it, the walk was a bit creepy in the dark.

That was when she heard it. A deep growl followed by a howl. A howl that sent tremors through her entire body because she had heard that sound before. It was the sound of a werewolf. It was close. So bloody close. She was sure it was onto her scent. For one wild moment she wondered if it was Remus, but it couldn't be. He was in the Shrieking Shack, that's what it was built for.

After a moment of being frozen with terror, she began to run. She was closer to Hogsmeade than she was to Hogwarts, but she didn't want to accidentally sick a werewolf on the unsuspecting villagers. At least at Hogwarts there were sure to be enchantments that kept werewolves off of the grounds.

She heard the padding of heavy feet behind her, catching up to her. Her wand was in her hand, but she couldn't think of a spell to use against a werewolf. Not without seriously injuring it, and it was likely that the werewolf was Remus. Normal hexes and jinxes didn't work on a werewolf. Like other magical creatures, they had enough magic in their blood to keep spells from affecting them while they were transformed. A Stunning spell wouldn't work. Nor would Impedimenta.

Without warning, a heavy paw caught her in the shoulder. She screamed and was sent sprawling to the ground, her wand knocked out of her hand. Her body skidded several feet before hitting a tree. She was showered with dead leaves as they fell from the tree she had hit. Her eyes searched the darkness for the werewolf and spotted it.

The creature was only a few yards away from her and closing in. It sprang. Luna threw her hands up to protect her face but it turned out there was no need. At the last second, a tall stag leaped between them and caught the werewolf in his antlers, flinging him back and emitting a deep grunt.

Sweet Merlin, that was James! Then the werewolf was definitely Remus. Sirius and Peter must be somewhere nearby as well. The werewolf was shaking himself off and getting ready for another attack. The stag, James, was stomping his hooves in warning. A black furry body blocked her vision.

The entire body of the huge black dog was shaking. Luna reached out and tangled her hand into his fur. "Sirius," she gasped. At the sound of his name, the dog's whole body stiffened and he turned his large shaggy head to gaze at her in wonder. How had she known who he was? "I'm hurt," she wheezed, holding her side. She was sure a few ribs were broken.

There was a whiney and they both glanced over to see James charging Remus down, directing him away from Sirius and Luna. The dog lowered his body and Luna fisted her hands into his fur, dragging herself on top of him. She was a small girl and he was a gigantic dog. He began to run, effortlessly, toward the castle.

Luna knew that he wouldn't turn back into a human. For one thing, it would make them even more of a target for Remus and Sirius could protect her better as a dog. Not to mention, he could run much faster with four legs than two. When they made it past the gates all the way to the front doors, Sirius turned into his human self.

He was frowning deeply at her. "Do you realize that this is the third time since the start of term that I have had to carry you to the hospital wing?" he growled, sounding angry.

"I'm sorry," she snapped, "but I didn't exactly plan on being attacked by a werewolf tonight!"

Arguing the whole way, Sirius carried her up to the infirmary. He watched with a scowl as Madam Pomfrey healed the broken ribs with a sharp flick of her wand and sent them back up to Gryffindor Tower. "How did you know?" he finally asked.

"That you are all Animagi or that Remus is a werewolf?"

"Both," he growled. They reached the portrait of the Fat Lady. "Bumbling Boggarts." The portrait swung open to admit them entrance into the common room. Luna went immediately to the empty couch and plopped down. How was she going to explain this?

"I do believe, dear boyfriend, that I told you many weeks ago that I can't tell you everything. You know there's something strange about me, but you don't know what."

"I have an idea," Sirius mused suspiciously.

"Oh really?" Luna raised a perfectly arched eyebrow.

"Yes," he said, "I think that there are actually two likely explanations."

"Do tell," she encouraged. Part of her felt very giddy that Sirius had two theories. Would either of them be correct? Surely not. Who had ever heard of a Time Travelling witch who was the granddaughter of your best mate? Would she admit the truth if he guessed it?

"My first guess," he said as he leaned in to kiss her on the top of her head, "is that you are a powerful Legilimens."

Luna's smile widened, "You're sharp, Black, I'll give you that, but no, that's not correct. Oppositely, I'm a powerful Occlumens. I can keep people out of my mind without any trouble. Unfortunately, I have difficulty getting into the minds of others. What's your second guess?"

"Well damn," he muttered, "I thought for sure the first guess was right. Alright then, my second guess is that you are a Seer."

So close. He suspected that she knew the future. He just didn't suspect that she was from the future. "Nope," she said simply with a shrug.

"What?" he asked in surprise, "Neither of those are correct? But then how on earth do you know all of the things you know? You must be somewhat important to Dumbledore because he and McGonagall both show you special attention. Are you some sort of spy for the Order?"

"Not yet," said Luna with a touch of pride, "but I hope to be. If I'm still here, I'd very much like to join the ranks of the Order of the Phoenix."

"If you're still here?" Sirius's eyes widened and his smile was wiped from his face. "You're not…are you dying?" he sounded horrified.

"No!" she squeaked, "No, I just meant that I don't plan on being here forever."

"What do you mean by 'here'? Hogwarts? England? With me?"

She chewed on her lip, "I can't tell you."

"Can't, or won't?" he challenged.

"Can't," she emphasized, "I wish I could, but I can't. Sirius, you knew what you got into when we started dating. You knew there were things I couldn't tell you."

"I hoped, that with time, you would come to trust me enough with your secrets," he whispered the words softly, looking down at their interlaced fingers as he spoke.

"It's not really my secret to tell," Luna looked uncomfortable and fidgeted a bit before saying, "It's getting late. We should go to bed."

"Will you stay with me tonight?" Sirius asked, his expression was innocent but she could see the lust burning in his eyes. The other Marauders were out and about for the rest of the night. They would be alone in his dormitory.

"Only if we just sleep. I'm not…ready…for anything else," Luna didn't tell him why she wasn't ready. She didn't tell him that she didn't want to tie herself to him anymore than she already had. It would only make it harder when she finally went back home.

"Just sleep," he assured her with a smirk, tugging her hand and pulling her to her feet.

Trusting him more than she'd ever trusted anyone in her life, she let herself be led up to his dormitory. She watched with wandering eyes as Sirius stripped out of his clothes, until he was in nothing but his boxer shorts. He was so gorgeous it took her breath away. His lean tanned body rippled with every movement he made, his dark shaggy hair begging her to run her fingers through it.

Luna stood there awkwardly for a moment before she, too, began to undress. Her robes fell to her feet, quickly followed by her shirt and skirt, leaving her in a skimpy pair of panties and a plain white undershirt. Sirius's eyes darkened with lust as he looked her over. He shook his head back and forth before lifting the duvet and motioning for her to climb in.

The bed was small, but not the smallest she had to share with someone else before. Sirius's body was hot to the touch and his skin was smooth against hers. He laid on his back, letting her drape her upper body over his, resting her head over his heart, hearing it's strong beats. Feeling his chest rise and fall with every breath. She squeezed her eyes shut tight, willing the tears that were forming not to fall.

Knowing that soon, too soon, his perfect chest would be scarred, bone thin, that his soul would be darkened and his dreams turning to nightmares as he faced over a decade in Azkaban. And there wasn't a damn thing she could do about it. Then, his untimely death at the hands of his own cousin. Luna's body convulsed as she worked even harder to keep her tears at bay.

"Shh," Sirius soothed, stroking her hair, as if hewere comforting her. "I'm here, Lu-Lu, I'm here," he murmured.

After a couple more sobs, she'd fallen asleep. Sirius held her relaxed body in his arms wondering what on earth he was supposed to do. This girl had secrets. Secrets that were haunting her. He could see them in her eyes. She knew so much more than she was telling. How could he help her if he didn't even know what was hurting her?

…..

Not a long time later, a girlish giggle stirred Sirius and Luna awake. "No one's here," they heard James mutter in a reassuring tone. Luna looked at Sirius with wide eyes. Sirius shrugged. Then there was the unmistakable sounds of two people kissing heatedly and the rustling of fabric.

Luna opened her mouth to speak but Sirius clamped a hand over her mouth and held a finger over his own lips, motioning for her to be quiet. They heard the curtains around James's bed opening and the subtle creaking of bedsprings as two bodies fell onto the mattress. Sirius searched blindly and quietly for his wand, which was under his pillow.

There was a gasp from the girl, a grunt from James, and Luna childishly slapped her hands over her ears. Sirius gave her a frown of sympathy before bringing up his wand lazily and casting a non-verbal spell around them. They could no longer hear James and his mystery girl, nor could James and the girl hear Sirius and Luna.

"What the hell?" Luna growled, "is James really doing…that….with some bint while trying to win over Lily?"

"Well," Sirius winced, trying to defend his friend, but knowing that this was pretty low. "Lily has been giving him the cold shoulder a bit lately, and you can't blame a bloke when he has certain needs…"

"Sirius Black," snapped Luna, "don't you defend him! You ought to go over there and tell them to stop."

Sirius almost chuckled at that, "Oh, I'm sorry, do you want me to watch my best mate shag a girl? Because I'm telling you right now, if I walk over there and pull those curtains aside, James will just keep on…doing…what he's doing."

"That wanker! I'm going to give him a piece of my mind! First thing in the morning," her cheeks were flushing red. She couldn't imagine interrupting them and didn't want to face the awkwardness that would entail.

"Well, we could always…" he said suggestively as he stroked her thigh. Luna blushed, just realizing that while she had slept she had thrown a leg over Sirius's waist.

"If you think I'm going to have sex with you in the same room that other people are having sex, you are insane," despite saying this, she didn't make any attempt to pull away from him. Oppositely, she snuggled into his side even more.

"It's not like we can hear each other or see each other," he pointed out.

Luna mumbled incoherently into his chest. Before Sirius could ask her what she had said, he discovered she had fallen back asleep. In a way he was relieved because during their talk, his boxers had grown progressively tighter. His cock was only a few inches away from her leg, which was wrapped around his waist and for one wild moment he wondered what it would feel like to have her touch him there.

Knowing he would have to be patient, he tried hard to concentrate on something other than how badly he wanted to be inside of the girl who was currently sleeping on top of him. It made him simultaneously uncomfortable and jealous to think of James, in the bed next to his, making love to someone. But Sirius would rather be doing nothing with Luna than everything with someone else.

…..

The next time they woke up, it was daylight. Faintly, they could hear birds chirping and Luna knew the spells Sirius had cast around them had worn off during the night. Luna put her hands on Sirius's chest and pushed herself up into a sitting position. She pulled up the thin strap of her tank top and ran a hand through her unruly hair. Briefly, she wondered how no one else had made the connection yet between her and James.

They had the same attitude, similar personality quirks, the same hair, and other various traits that resembled each other. Gently, she shook Sirius awake. He looked up at her groggily and the thought crossed his mind that he wanted to wake up with her every day. Before he could dwell more on that thought, she quirked an eyebrow at him and jerked her head toward James's bed.

Sirius gave a noncommittal shrug and Luna squirmed out of the bed. "James Potter!" She was rewarded with two surprised gasps from the bed that had the curtains drawn around it. The rant continued, "I know that you have a girl in there with you, so don't try to hide it! I can't believe you would do that to Lily! I am disgusted with you, you worthless tosser!"

A very messy head of raven black hair peeked out from between the curtains. James Potter, sans glasses, was grinning at her like he found her amusing. Luna put her hands on her hips and glared at James with a look that made her almost identical to her mother. It was a Weasley glare and Luna knew firsthand exactly how it felt to be on the receiving end of one of them.

"Go back to bed, Lu-Lu and quit being a hypocrite," James said with a laugh in his voice. That was when she looked down and realized she'd slept in her knickers the night before. Flushing Weasley red, she scrambled into her wrinkled skirt, which was on the floor beside Sirius's bed.

"I am not being a hypocrite," she defended, "Sirius and I did nothing but sleep last night. Even if we had done, erm, other things, at least neither of us are stringing someone else along! How can you grin at me like that? It's positively loathsome what you've done!" The more she yelled the angrier she became. "Where's my wand? I'm going to hit you with such a forceful Bat Boogey Hex that you'll have to go to the hospital wing!"

"Luna," a small and embarrassed voice spoke up for the first time. Luna froze, one hand gripping Sirius's duvet, the other pushing Sirius aside as he tried to stop her from getting to her wand. She recognized that voice.

"No!" she gasped in surprise.

Lily Evans, turning every shade of red imaginable, peeked her head out beside James's. "James wasn't messing around with another girl," she explained, "It was me."

Luna squealed happily, clapping her hands together and rushing to wring James's hand. "Congratulations!" she declared, "I'm so happy for you two! This is excellent!" Jumping up and down, she leaped onto the bed she had slept in the night before, saying, "Isn't this the best thing ever?"

Sirius, who was lying on his bed with Luna's feet on either side of him while she jumped, nodded in agreement, "Yes, you bouncing around like that over top of me is most definitely the best thing ever, love." Without giving her a chance to become embarrassed, he sat up, knocked her legs out from under her and caught her up in his arms and kissed her.

"Were you two um, in here, the whole time?" Lily sounded like she had forced the question out and did not really want to know the answer.

"Yes," said Sirius unashamedly.

"We didn't listen!" said Luna. "We heard James come in with someone and Sirius immediately cast a few charms so we couldn't hear you and you couldn't hear us."

"Hear you what exactly?" asked James suggestively.

"For the last bloody time, Sirius and I have not slept together yet!"

"Yet being the keyword," James was promptly smacked in the face with a pillow for that comment.

…

A/N: Okay. SPOILER ALERT! Here's a rough sort of outline of where this story is going: several more chapters of Luna stuck in this time. Then, Luna will go back to her time. There will be a series of chapters about each character she left behind. The chapter title will indicate which character the chapter is focusing on (i.e. there will be a chapter titled "Mary MacDonald" and "James and Lily Potter" etc.). The last one of those will be Remus Lupin's. Then there will be several chapters on what happened when Lily returned to her own time and how she is dealing with her life after the time travel trip. It will all be very interesting!

SPOILER ALERT OVER!

I hope everyone liked this chapter. Next chapter I will go back and explain what happened between James and Lily leading up to their big night together! Small lemon, so be prepared for that! If you have any comments or questions, you know where to leave them and I love receiving them!
