*** One week later ***

It had been an awkward week at The Burrow; Hermione and Ginny had taken to not really interacting with each other, other than being perfectly polite when necessary. Mr and Mrs Weasley had been lovely about it, offering the usual advice about "everybody fights occasionally" and "it'll all feel silly in a few years". Hermione felt utterly isolated, Ron sided with his sister, Harry didn't want to upset Ginny for obvious reasons. That was probably the worst thing: still having to sleep with Ginny, knowing she'd been satisfied by Harry - but unable to satisfy herself in the presence of her former friend. In fact, she'd almost completely lost her conscious sexual appetite. She'd masturbated once in the bathroom, but felt utterly disgusted afterwards. Yet somehow she still woke in the middle of the night having had a wet dream about Harry and Ginny - all the more vivid having actually seen them fucking like animals.

Luckily for them both, school started tomorrow, so they only had to be in such close quarters for one more night, then they'd be off on the Hogwarts Express first thing in the morning. It was mid afternoon, and the girls had been sent my Mrs Weasley upstairs to pack their suitcases. Avoiding contact of any kind, they placed their cases on the bed opposite each other and began placing cloths quickly, desperate to escape from the suffocating astriction. The uncompanionable silence was broken by Ginny:

"I am sorry, Hermione. I hope you know that."

Hermione took a deep breath, really not wanting to talk. "I just don't know what you were thinking, Ginny."

"I was stupid. No excuses."

"I can't accept your apology."

"I understand. I wanted you to know before we got back to school... that I did enjoy it. The sex. The only thing I regret was not realising you were getting too involved."

"..."

"And I was maybe hoping... that when we get back to school, since it will be harder for me to be with Harry, and we both obviously have, um... large appetites... that we, if you wanted to - and felt up to it - might... do it... again...?" Nervously looking down into her suitcase, unsure whether she had ruined their friendship forever. "We don't have to be friends, or anything."

"I don't know, Ginny."

"That's okay. It was just a thought."

"..."

"The other thing... I just... should warn you, I've been talking to Luna -"

"Wha-?"

"Not about us, don't worry! But about boys, and girls. And - I'm not sure how to say this - Luna likes you."

"Like a friend...?"

"Like she told me in a letter that she had a... dream... about you. And me. And I think she was hinting that we might... when we're back at Hogwarts... the three of us..."

"Why on earth would you tell me that? Are you just trying to humiliate me more? Was telling Harry about my... thing... not enough?"

"No no no, 'mione - not at all! I'm just giving you the heads up to watch out. Because I know I hurt you. It kills me. And I don't want you to get caught up with Luna and get hurt again. So just, watch out?"

"Okay. Erm... thanks. Sorry I got defensive."

"It's okay, I know you don't really like me right now."

"That's not it, Gin. I just... need time."

"I understand, forget what I said about us... earlier."

"I'll think about it."

"Wait, really!?"

"It was fun, and now that I know there's nothing romantic between us I can't get hurt again, right? Just sex."

"Right... think about it."

*** The next morning ***

Scenery rattled past the windows, the whistle of the scarlet engine howling in the distance. Hermione sat alone in her compartment, silent except for the clattering of the carriages over the tracks. Staring off, focussing somewhere between the end of her nose and the Scottish mountains in the distance, she tried to process what Ginny had told her and suggested yesterday. Seemingly only recently had she discovered masturbation, and a couple of weeks since she had been introduced to true pleasure. And now she was facing the prospect of a threesome, with Ginny and a girl she had never even considered... sexual. Her thoughts were broken by a tapping on the window, and the compartment door loudly sliding open, revealing Luna. Somehow the first and last person Hermione wanted to see right now.

"Are you okay, Hermione? Ginny tells me you had a falling out, but won't say what about. She's really upset, you know."

"I don't know, Luna."

"May I come in?"

"Sure."

Luna sat opposite Hermione, and followed her eyes out of the window, waiting for her to speak first.

"Luna, have you ever had a crush on someone?"

"Of course I have."

"I had a crush on Ginny. But she told me she didn't feel the same way."

"Oh. Hermione, I'm so sorry. That must be awful."

"It was my own fault really."

"How so?"

"We... um... had... sex. And I got caught up in it."

"Oh!"

"And then... you promise you're not going to tell anyone anything I'm telling you?"

"I promise, you can tell me."

"And then I saw Ginny and Harry... and they were obviously in love. And I overheard Ginny telling Harry about me. Intimate things." She blushed red and tears formed in her eyes.

"That's awful! Why would she do that?"

"I don't know." She rolled her eyes around and wiped a tear away. "So we didn't talk for a week. And then last night, she tells me she wants to start... having sex again at school. And that apparently you would want to join us?"

"I... Hermione... I didn't know you were going through this, otherwise I would never have suggested..."

"It's okay. I think it might be good."

"What?"

"We all have needs, right?"

"Right..."

"And it is better with two people, so why not even better with three?"

"I... it gets complicated. Last year, I had one threesome with some girls in the year above. It was really fun, but only because we knew it was just sex."

"I'm not even sure I want to. I'm thinking about it."

"Sure..."

"..."

"..."

"I should go put my robes on, we'll be there soon."

"Bye, Hermi-" but she was already out of the door.

Hermione rushed into the bathroom, closing the door behind her. She propped herself up by her hands on the sink, looking into her own eyes in the mirror. What had just happened? Had she really told Luna about her and Ginny? Had Luna admitted to having a crush on her? Did she agree to a threesome? What was going on? Her mind reeled, thoughts of Luna and Ginny racing through her mind. She began to undress, removing her jumper and unbuttoning her jeans, when the door behind her slid open and Luna appeared behind her. Hermione spun around in shock, and Luna wordlessly pushed a kiss upon her. At first taken aback, she tried to push Luna away, but to no avail. Luna was determined! And a damn fine kisser. Quite unsure what she was doing or why, Hermione slowly began kissing back, becoming increasingly intoxicated. Blushing bright red, she felt the familiar feeling of arousal spreading through her, a wet spot surely appearing on her panties. In a surprise twist, Luna slid her hand down her own skirt, and moaned softly as she touched herself, right there - kissing Hermione as she did so. Hermione wrapped her arms around Luna's neck, holding on as she got wetter and wetter and pulled her in tight. After over a week of denial, Hermione was not surprised she was this horny. Luna began moving faster and faster, sweat starting to form and her kissing becoming less and less lucid. Soon her legs were shaking as she ground herself against her own fingers, pressing her body to Hermione's as much as possible.

"Aaahhh... ahhhh... uhhhh..." Luna grunted and moaned, and orgasmed - barely able to stand and she rocked her hips back and forth against Hermione. "Oooohhhh! That was a good one!" She whispered as her climax retreated. She took her hands out of her skirt and sucked her fingers clean, with a slightly drunken smile on her face.

"Luna that was so hot! I'm so horny right now, I haven't... since I fell out with Ginny."

"Let's fix that!"

"Uh huh!"

Luna placed her hands on Hermione's hips, pushing down her already-undone jeans and placing her fingers over her panties. Firmly rubbing, right on Hermione's clit, she forced her back so she was perched on the sink, and resumed the kissing. Already soaked, the feeling of her undies rubbing her clit so precisely drove Hermione almost straight to the edge. Breaking away from Luna's kiss, she removed her underwear and hugged her body tight to Luna's enjoying the feeling of her cotton robes on her near-naked body. Resuming the rubbing, this time directly on the bare clit, Luna made sure to get it exactly right. Before long, Hermione was stifling a scream and she buried her head into Luna's neck and tensed through her strongest orgasm yet, wrapping her legs around Luna and thrusting her sensitive clit into her fingers, cumming until she could cum no more, spasming as Luna continued slowly brushing her pussy. The two girls locked in a passionate embrace, Hermione still up on the sink, pussy pressed against Luna's crotch as her cum dribbled down onto the floor.

*** Later, Hogsmead Station ***

Hermione and Luna emerged together onto the platform, still pink in the face. Hermione had just had her first meaningless sexual encounter, and it had unlocked something in her brain. Sure, Luna was her friend, and they had orgasmed together - but she didn't feel anything romantic towards her at all. Not like she had with Ginny.

She caught sight of her redhead friend across the bustling platform, and excused herself from Luna's company and made her way over.

"You look... refreshed. Have you seen Luna?" Smirked Ginny.

"Yeah... she's... great!"

"So I've heard from the year above."

"Ginny... I think I get it now. I'm still mad that you betrayed my trust, and it'll take a while for us to be friends. But I think we'll all three need... refreshing. If your offer is still on the table?"

"Of course! Hermione that's great! You know... I brought that notebook with me!"

"Oooh, I can't wait!"

"I guess I'll see you tonight!"
