The knot of anticipation had been growing in Hermione's chest all day. She had double and triple checked every calculation. She'd read every book she could find on magical bonds. She had created a mental list of every conceivable side effect of the bonding process.

But now there was nothing more she could do. It was a Friday night, so everyone was slow to go to bed. It wasn't until after midnight that Hermione was finally alone in the common room, and another half hour before Harry and Ginny were able to sneak out of their dorms.

Harry came down first, invisibility cloak in hand. "We've got a problem." He said seriously.

"What?"

"I was checking the Marauder's map when I was in bed… Dumbledore spent some time outside the Room of Requirement."

Hermione's brow furrowed "He might have set a ward."

"I don't know what to do. I can't think of anywhere else where we wouldn't be found, but has the right atmosphere."

Ginny followed about ten minutes later, and greeted Harry with a kiss. "Honestly, you guys can't keep your hands off each other for ten minutes?" Hermione groused.

The two of them shared a look, grinning widely. "No." Ginny said simply. As if to prove their point, the two linked arms, drawing them closer together.

Hermione shook her head, but was smiling. They really were perfect for each other.

"Well, I'm down for doing it in a broom cupboard if we have to." Ginny suggested, after they had explained the situation to her.

"Not enough room." Hermione shook her head.

"Abandoned classroom?" Harry tried.

"Luv, we'd get caught for sure."

"The shrieking shack?"

"Seriously?" Ginny raised an eyebrow.

"Well I'm not about to suggest the chamber." Harry groused "We don't have many options."

"Err, I have an idea." Hermione said, somewhat sheepishly.

"What?" Harry and Ginny asked simultaneously.

"Well, you see, I stumbled across it in my third year. I used to sleep there when everything became too much, but I couldn't go back to the common room because of time travel." Hermione rambled. "I'm sorry I never told you! But I couldn't at first because I couldn't talk about the time turner." And she felt bad about lying to them about that as well "And afterwards, it just sort of slipped my mind in the chaos and it just-"

Harry put his hands on Hermione's shoulders, rubbing them soothingly. "It's alright 'Mione, I don't tell you every detail of my life either. So, what is this room?"

"It's a little study area off from the library. It's got chairs, a desk… a bed."

"So, it's perfect, basically." Ginny summarized.

Maybe not perfect, Hermione mused. The original plan hadn't been for Hermione to go with them. It was Ginny that had brought up that if something went wrong with the ritual, or maybe even if something went right, they would need someone to help them, if only to get them to the hospital wing. When they were planning to be in the room of requirement, Hermione could have just been separated from them- giving the couple some privacy. That wouldn't work now, but it was the only way that Hermione could see them doing this ritual while they were still at Hogwarts.

"Well, it's the best we're going to get." Hermione temporized.

Harry only needed a moment's thought. "Alright, let's do it."

Hermione remembered how she, Harry, and Ron would be able to drape the cloak over themselves when they were first years. They'd grown quite a bit since then, so it was a tight fit. Hermione blushed, feeling Harry's body press against her from behind.

Hermione hadn't been able to act the same around Harry since their first kiss. She noticed him now. She could tell every time he and Ginny went off to fuck and how disheveled they both looked when they returned. Her eyes began searching for him when she wasn't otherwise focusing on anything, taking him in. Her mind would wander at the most inopportune times, imagining what it would be like when she and Harry explored each other- when they would become intimate.

The room was just as she'd remembered it. Small, but not cramped. Comfortable, but not overly so. As best she could figure, it was some sort of study lounge that had been long forgotten.

"Alright, I need to set things up." She announced. The bed had to be moved to the center of the room, so she could place the runes around it. Those runes where engraved on small polished stones that Hermione kept in her bag. While Harry helped her with the bed, neither of them could really help with placing the runes. She was the only one who knew precisely where they needed to be, there was a margin of error with these sorts of things, but this was not the time for taking chances like that.

She used a measurement charm to determine where to place each stone. She'd move her wand between two points, tracing out a glowing white line on the floor, and the exact distance would be displayed floating just above and between the two points in glowing white text.

Soon the floor was a mess of lines and numbers, but each stone was in its place. Hermione dispelled the charms. "What should I do now?" She asked "I could leave, but…"

"Don't leave." Ginny answered. "We could pass out after the ritual, or really, anything could happen." While she made a good point, the glint in her eyes told Hermione that her intentions weren't entirely pure. Ginny, Hermione realized, liked the idea of her watching them.

"I just don't want to intrude." If Harry and Ginny really were about to form some sort of soul bond, it seemed almost sacrilegious to just… be in the room with them while it happened. It should be between the two of them.

"Look." Ginny said "I know this isn't optimal. Nothing about this situation is ideal. But we're about to perform a ritual that has never actually been done. It's not a matter of what we want. It's what we need." She looked to Harry to confirmation, who shrugged and nodded.

Hermione sighed in acceptance and nodded. "So, are you two ready then?"

"Yeah." Harry nodded, a look of determination flashing through his eyes. Hermione had seen that look before, before the first task, before going into the Department of Mysteries, before he left her to go after the philosopher's stone.

"Yeah…" Ginny echoed. She was staring up at Harry, seemingly captivated. Hermione couldn't blame her, Harry was quite captivating.

Hermione took the invisibility cloak and hid herself. At the very least she could give them the illusion that they were alone. She couldn't even properly sit at the desk- it was half within the runic circle. Instead, she had to sit in the armchair in the corner of the room. She turned it to the side, so at least she wasn't directly facing the bed, but she could still see them. She pulled a book on magical forms of telepathy out of her bag, but she admitted to herself that the distraction probably wouldn't work.

At first the two of them just held each other, whispering soft words to each other that Hermione didn't try to listen in on. It seemed as if Ginny were comforting or reassuring Harry. But then their words were replaced by the sound of mouths meeting. Hermione's gaze was drawn from her book. They were kissing, and Hermione was surprised at how quickly they had escalated. They'd gone from hugging to perhaps the most passionate snog Hermione had ever witnessed in a matter of seconds.

Hermione quickly realized just how much she had to learn. The way Harry and Ginny were kissing… they were in perfect synch. Even as they snogged passionately they seemed to sense exactly what the other was doing, what the other wanted. Their lips separated, only for Ginny to bare her throat to Harry. Harry took advantage, pressing kisses down from her jawline her collarbone. "Oh fuck luv. Just like that." Ginny moaned.

She felt herself growing hot. Her book was forgotten as Hermione was drawn in by the scene. God, she wanted that. She wanted Harry to kiss her like that.

Harry's hand palmed one of her boobs. "Gin, do you just not wear bras anymore?"

"Only if you ask nicely." She teased "What are you going to do about it?"

Harry's grin turned feral. "Take off your shirt and I'll show you."

Ginny did as he suggested, and lifted off the shirt in one fluid motion. Harry was looking at her like she was a goddess. "Perfect." He moaned, going back for another kiss. His hand began fondling her breasts, eliciting soft sighs from Ginny whenever their lips parted.

Harry backed Ginny into the bed, and the two of them toppled over. Hermione shifted over so she could see properly. They hadn't even interrupted their kiss. Harry was resting between her legs, which were parted for him. He was propping himself up with one arm, while the other continued to fondle her breasts.

Ginny broke their kiss "Shirt." She muttered, her hands grabbing at his loose-fitting T-shirt. Harry rose up so that he was resting on his knees and pulled his shirt off. Hermione's jaw dropped just a tad as she took Harry in. He wasn't a scrawny boy anymore. He was still thin, but really, he was fit. Without even realizing it, Hermione's had had gone to her breast, slowly caressing it.

Ginny bit her lip as she smiled. "Hermione's getting an eyeful right now."

Harry eyes briefly looked at the (to him) empty chair that Hermione was sitting him, and she froze. "I guess she is." He agreed.

Hermione had never masturbated before, but watching Harry and Ginny had awoken something in her. It was like trying and failing at a spell all class period, only to have someone show her the correct wand movement, making her realize she had the wrong idea the entire time. What Hermione had imagined, believed, sex to be like was a pale imitation.

The two continued to undress each other, all the while stroking and kissing every piece of skin they could find. How Hermione wished she was in Ginny place, but at the same time she wondered if she ever even could be in Ginny's place. What they had was uncatchable, untamable, but oh did Hermione want a taste. She'd now partially unbuttoned her uniform shirt, and wormed her hand underneath her bra. The movements of her fingers were inelegant, but nonetheless sparked tingles of pleasure.

The instant that Harry had kicked his pants off, Ginny's hand went to the erection that was obviously tenting his boxers. "Ooooh yes. Do you want me to let your cock out, luv? It's so hard… aching, I bet Hermione's absolutely gagging to see it." Ginny moaned, rubbing her hand up and down the bulge. Hermione's stared, enthralled at the display. Harry's body was magnificent, his chest has flushed and heaving, and his entire body was tense with defined muscles. The only part hidden was the cock that was straining against the fabric of his boxers. Hermione had thought she knew what attraction was. She thought that what she felt when she saw Victor or Ron was what it meant to be attracted to someone.

But it wasn't. Well it was, but it was only the tip of an iceberg Hermione had never seen coming. She now knew that attraction was being literally incapable of looking away, it was wanting to kiss every bit of skin she could see, it was the desperation to get closer, as close as possible to him, and it was feeling, in that moment, that nothing else mattered. It was clear that Harry had long felt that for Ginny, and Ginny had felt that way about Harry for years. But it was only now, staring at Harry's nearly naked body, that Hermione realized it was possible to feel like that at all.

Her other hand was underneath her skirt, rubbing herself through her panties. She knew that she shouldn't, but she couldn't not. Any bit of restrain had been obliterated and there was a desperate, hungry heat in her core that demanded satiation.

Ginny pulled down Harry's boxers, and when Harry's cock sprung free Hermione let out a long whimper. Oh, was all Hermione's mind could manage. She'd seen a picture of a penis, an erect penis, in a sex ed book her parents had bought her before she left for Hogwarts. Hermione hadn't thought much of it- it was just a penis. It didn't seem so special. She'd overheard Lavender and Parvati gossiping about sex- most embarrassingly when they'd gotten into an in depth discussion of what Harry 'must be packing' based on what they'd seen from his rather tight quidditch pants, and most painfully when she Lavender talked about giving Ron a blowjob. Through giggles they'd speculate on how big a particular guy was and Hermione just never got it.

But now she did. Because a penis wasn't just a penis, or at least not always. When she saw Harry's erection she saw lust, passion, sex, power, and virility all wrapped up in one package- and it was quivering as if the power behind those concepts were trying to break free.

The couple froze at the noise Hermione made, and Hermione wished she could sink into the floor and disappear. Ginny turned around with a feral smile and crowed "What did I tell you Harry? Gagging for it." She wrapped her hand around his cock, and the instant she made contact, his expression turned, if only for a moment, to unadulterated bliss. "C'mon luv, I want to show her something."

Ginny lifted herself off the bed, still holding Harry's shaft. Harry followed her, and Hermione was amazed at the sudden shift in their dynamic. One moment Harry seemed to be in control and the next Ginny was leading him around by his cock. Hermione was forced to pay attention to the redhead who was now aggressively approaching her. Her face was flushed, her nipples were diamond hard, her panties were soaked through, and her arousal had wetted the top of her thighs. She was a combination of feminine curves and sinuous muscle. It seemed like her entire body was filled with potent energy, just as Harry's was.

Ginny ripped the cloak off of Hermione's body. The brunette had moved her bra downwards in her ministrations, and one of her breasts had spilled over and out of her partially unbuttoned shirt. She'd hiked her skirt up, and both of them could clearly see how her fingers were rubbing at her stained panties.

Harry's eyes roamed up Hermione's body with burning lust. Hermione began stuttering "I'm sorry I'm so so-" Ginny silenced her with a finger to her lips and a shake of her head.

"Harry." Ginny stepped back, taking in her boyfriend "Kiss her."

In one stride Harry was upon her. His kiss sparked fireworks within her. Her body arched upwards almost painfully, trying to but just failing find his. She didn't even know what noise she made, but it was whatever happened when one lost control of their vocal chords, but was muffled.

Her hand, the one that was slick from rubbing her panties, went to grab his cock. However, before she could, Ginny intercepted her, grabbing her wrist. Hermione briefly fought her, but the redhead easily overpowered her, pinning her hand the arm of the chair. While Hermione spent all day studying, Ginny played quidditch, explored the castle, and got into trouble, and it showed- Hermione hadn't realized there was any disparity in physical strength between them until now.

Harry pulled back, and Hermione whimpered. Panting from the kiss she'd just received but also trying and failing to wrench her hand from Ginny's grip. "Hermione. I let Harry kiss you, but this is our night. Harry and I are going to fuck. We are going to give each other orgasms more powerful than you've ever experienced. And you are going to watch."

Ginny took a hold of Harry's cock again, and let her panties slide down her legs. Harry's attention completely switched back to her, and Hermione felt almost like she was back under the invisibility cloak.

Ginny sat on top of the desk, which was the perfect height to align their pelvises. It also put them right in front of Hermione. "Fuck me luv."

"Oh, I will." Harry growled, and with that he gripped her hips and thrusted himself insider of her. He sheathed himself completely within her with one stroke, and Hermione would never forget the look of pure ecstasy on Ginny's face, or the way she moaned "Oh H-harry. Oooooh."

Harry began thrusting into her in earnest, and Ginny wrapped her legs around his hips, using them to push them together even more powerfully. Hermione gave up all pretense and pushed her panties down. Harry and Ginny were fucking just feet from her. They were right in her face.

If Harry was a god (and Hermione was ready to get on her knees and worship him) then Ginny was his goddess. They'd seemed to transcend the world around them. His entire body seemed to be working to fuck her, and hers for him. Muscles flexed, flesh slapped against flesh, breathing turned harsh and was interrupted by moans and dirty talk.

She could feel the magic rising in the air, like electricity. Hermione had always had something of a sixth sense when it came to magic. If she concentrated, she could sense the gentle hum of the Hogwarts wards. She could sometimes feel the magic radiating off of powerful magical displays, and people. She remembered shuddering from the magic Harry had radiated after casting that patronus in their third year, or how she could feel him before the first task, and occasionally during the DA.

She could feel his magic, both his and Ginny's magics, now. Pulsing off of them in increasing intensity.

Hermione noticed that the rune carvings on the stones she'd placed so carefully were beginning to glow. Each one of the five runes glowed a different color- blue, red, yellow, green, and purple. The colors began to grow into the air from the runes, like branches from a tree. They also sprouted from various points along Harry and Ginny's bodies. If the couple noticed, they didn't care.

It was… beautiful.

Ginny's speaking, and Harry's moaning and occasional 'God, Gin' became higher pitched and desperate. Harry's thrusting, somehow intensified, and the desk was now hitting the wall with each stroke. The colors grew brighter, and the vines of light grew so thick that Hermione could barely see them.

All she had was the sound of them. Their moans, the slap of flesh on flesh, the squelch of Ginny's juices as he fucked her. And suddenly, Ginny was crying. "Fuck! Please! More! More! More! I want it! I want it! I want it all!" Then, Harry cried out like Hermione had never heard him before, with joyous tears, and there was a beat of silence.

Then they screamed in unison, and Hermione's world exploded in light. A wave of magic rippled out from the room. When it passed Dumbledore's office, it spun an instrument that looked somewhat like an anemometer, though the Headmaster was not in the room to notice it. As it passed beyond Hogwarts' wards, it began to dissipate. The electronics in the few rural muggle houses in the area close to Hogwarts flickered as it passed.

Elsewhere, the self-proclaimed Lord Voldemort woke from sleep, screaming.
