"…The Somnium Vitis plant has been studied by Mind-magic specialists for centuries in order to ascertain how the plant is capable of creating such accurate and poignant dreams in its victims. To this day, researchers the world over have only come to the conclusion that despite not having a brain or a tangible soul, the Somnium Vitis plant does in fact have a form of consciousness which can be manipulated by a skilled practitioner of the mind-arts…"

'Magical Botany, the Herbologist's Guide to Herbology' by Mercurius Saltus

A week following their first coupling, the whole of Hogwarts knew that Hermione Granger had begun to date Luna Lovegood.

Perhaps, had it not been the wizarding world, they would have been met with judgement and derision. Many people viewed homosexuality as something against nature, something wrong.

Considering the strikingly Victorian-era societal expectations, Hermione found it incredibly ironic that the conservative wizarding world was shockingly liberated on the subject of sexuality.

Really, this was the result of purebloods intermarrying for generations. Homosexuality seemed to be less important in the people's eyes when there was already an issue with encroaching incest starting to eat away at society's upper class.

Cultural stagnation had to have some benefits, no?

As it was, Hermione and Luna were duly congratulated by their friends. Responding to a letter informing him of the news, Ron asked them to, "Send some pictures, would you? You know, to cheer George up!"

Ronald Weasley received a howler the next morning, and Diagon Alley was treated to a three minute lecture on decency and tact.

When Harry was personally delivered the news by the happy couple, however, Hermione, ever conscious of how her best friend was feeling, noticed a flash of disappointment gleam through his eyes for a second before he was grinning and congratulating the two.

When she locked eyes with Luna, she saw that her friend had seen the same look. Further conversation when they were alone led them to the joint agreement to see if they could finally bring their friend out of his unending funk.

"So let me get this straight," Harry said, looking at Luna and Hermione in disbelief.

"You two are having sex with a plant. You feel like I'm depressed so you want me to join in and loosen up, and to do that you thought you would try to seduce me and try to trick me into the greenhouse, am I getting this right?" he continued.

With blood dusting her cheeks pink, Hermione nodded her head, looking into her friend's eyes defiantly. Beside her, Luna's dreamy smile had taken on an abashed tilt, embarrassed for having been caught out in their attempted 'covert' seduction.

In truth, it was probably bound to fail from the start. The seduction had begun with Hermione and Luna acting more clingy than normal. They each gave Harry a full bear hug when they saw him in the morning. On the way to breakfast, they had wrapped themselves around his arms, and after classes had passed they studied whilst leaning their heads on his shoulders.

Harry wasn't a moron, and caught on pretty fast after that. A few pointed questions saw Luna slip up on their cover story, and from there the rest came spilling out from the flustered pair.

"We really do want to help you, Harry," Hermione said matter-of-factly, fighting down her embarrassment.

While a smirk might have appeared in years past, only a single eyebrow rose on his face, highlighting his disbelief. "And I'm supposed to believe that you'd let me into a threesome not even a month into your relationship?" Harry scoffed.

"Hermione, that's the kind of stuff that a guy fantasizes about. You don't have to tease me to cheer me up, you're my friend," he finished, his lips finally lifting in a fond smile.

Hermione's lips thinned. Luna, quickly detecting the shift in the atmosphere, shivered at the feeling of her mistress's magic which permeated the air in response to her ire.

Stepping forward and seizing Harry's collar, Hermione began to drag the wizard down the hall. "Well Harry, friend or not, I've been looking forward to fucking you since Luna and I agreed on it last night. If you aren't going to respond to seduction, then I'll bloody well drag you there myself!" Hermione growled.

Following after the pair, Luna smiled triumphantly when Harry didn't resist beyond muttering to himself about crazy witches.

"So what is this plant you have called?" Harry asked them.

Luna recalled the textbook entry Hermione had shown her after she had searched through the library. "It's the Somnium Vitis plant. It's well known for its use in Dreamless Sleeping Draught, although in its untransformed state it causes intense dreams. The secretion it gives off is addictive even in small quantities, and has a reputation for ensnaring witches and wizards to leech off their ambient magic," Luna answered him.

Harry blinked.

"I know that plant, there was a long essay by a Thai wizard named Wiyyad that I read. He kept postulating that it was semi-sentient, and what that meant for legilimancers," he said.

Hermione snorted, "If it doesn't involve you cheering up in the next two minutes Harry, then shut up and keep walking."

Harry frowned at the witch, noting her hurried pace and the way her eyes had taken on a far darker hue than their normal cocoa brown. Normally, Hermione would be far more polite; not this demanding or impatient.

Glancing back at Luna, he caught her gazing at the bushy haired girl with undisguised longing, taking in her flushed cheeks and stormy eyes.

Harry cast his mind back to what he had read in that essay, and suddenly smirked dangerously as he recalled one specific passage about the possibilities a skilled legilimancers might be able to take advantage of if they were to encounter the vine.

Exiting the castle and making their way across the grounds, Hermione all but shoved Harry into the greenhouse before slamming the door behind herself and Luna.

"Legilimens."

The two girls found themselves suddenly yanked into the air, drawing delighted yelps from their lips as they breathlessly anticipated the approaching pleasure.

Hermione, currently held upside down, turned her eyes to where Harry should have been in a similar position, but frowned when she noticed that he was currently standing perfectly still, feet solidly on the ground.

Her eyebrows creased when she took in the cool smirk he sent her way.

"You know Hermione, you should have let me finish earlier. You might have learned that skilled mind-mages can take control of the Somnium Vitis plant. It doesn't really have a consciousness to fight back with," he taunted her playfully.

A soft growl escaped Hermione's throat as she realized how thoroughly she'd been had. Then, she found herself once again being held right-side up, the vines curling around her keeping her limbs held extended. To her right, nearer to Harry, Luna was in a similar position.

Harry's wand, held loosely in his hand, flicked again, and their clothes vanished.

Hermione's face flushed, feeling a pulse of arousal run through her as a quickly growing pools of molten, liquid heat began to pool between her legs. She began to struggle against the vines holding her, desperate to take control of the situation and of the devilishly teasing boy in front of her.

"Ah-uh, Hermione. You're not in charge anymore. You lost your position on top the second you decided I was going to be a part of this, and now you get to take your punishment for that," Harry told her, his voice growing deeper as his eyes darkened until the sparkling emeralds became lightless onyx.

Hermione felt a shiver run through her body; her primal desire to take and mark and dominate stunned by this declaration.

Harry's smirk grew wider. He began to walk between the two girls, his hands tracing the pale, smooth skin of their bellies, moving up along their sides before lifting off the porcelain expanses.

He turned away from Hermione, focusing his attention on the wide-eyed Luna. Hermione felt a surge of fury wash through her.

'She's mine!' Hermione snarled within the depths of her mind.

His hands began to roam Luna's body, tracing random patterns up and down her spine, rubbing along her perfectly defined shoulder blades, sensuously stroking his fingers up the delicate contours of her collarbone and throat.

Shivers wracked the blond-haired girl as his touch sent luxurious waves of heat aflame on the skin left behind by his trailing hands. Her body squirmed as her eyes met those of her Mistress', seeking guidance on how to handle this befuddling treatment.

Hermione saw her last chance to retain her hold over the lithe, thrashing blond, and opened her mouth to assert her own dominance over her.

A vine gagged her within an instant, and her incensed gaze met Harry's, who's own watched with idle curiosity as, by force of habit, she began to suckle the vine curling itself around her tongue. Her mind began to fog as the additional surge of the aphrodisiacal fluid began to once more set her nerves alight.

Harry, once again circling around to Luna's front, leaned towards the blonde's face and suddenly pressed his lips against her own. She recoiled for a moment before her arousal reappeared full-force. Her own lips suddenly reciprocated the bruising pressure his own exerted.

Harry's hands rose, meeting her pale breasts, thumbs circling the areola before his forefingers drew together to pinch her coral-pink nipples. The gasp that was pulled from her throat allowed his tongue to suddenly invade her mouth, quickly asserting dominance over the overwhelmed schoolgirl.

Luna, accustomed to submitting to her other lover, relaxed under Harry's ministrations, too far gone into subspace to register the shift in her subconscious perception of the most powerful presence in the room.

As his lips left hers, a thin string of saliva was left connecting their lips, before it lost strength and swung back to trail down Luna's chin and collarbone. Her eyes, now stormy grey and dazed, stared at him pleadingly. The sight made Harry's pants tighten uncomfortably, and without a thought he vanished his own clothes so that he was in a similar state of nakedness as the girls.

Harry gestured with his hand, conjuring a padded table in the center of the room. Luna yelped as the vines suddenly shifted so that she was spread eagled, face down against the table. Squirming as the cool padding met the unbearable heat of her chest and stomach, she suddenly stilled as she felt Harry's warm touch caress her pale, flawless back, tracing a line up her spine and making her arch upwards deliciously.

"You need to relax, my little Moonbeam. I can help you with that; just lie still and embrace what you feel," Harry told her, his voice soothing and warm.

Luna tried to glance at her Mistress, but the table faced her deliberately away from her while the vines ensured she could do no more than squirm and twist her body a few inches in any direction.

Luna felt a cool, familiar substance make contact with her back. Twisting her neck as far as she could, she saw Harry directing one of the vines to secrete as much of its fluid as possible onto her.

"Relax, my Moonbeam. You want to feel good, yes? I can give you bliss; you just have to listen to me. Relax, and don't think; just let it all wash over you," Harry soothed her, replacing the worry for her mistress' opinion with his tender smile.

Luna let her body loosen itself, trusting Harry to fulfil his promise.

His warm hands once again made contact with her back, spreading the fluid around her spine and rubbing it into her skin, making her glisten in the moonlight. His heated touch, combined with the arousing effect of the plant's fluid further clouded her mind, leaving Luna in a deep state of debauched bliss as sensuous, carnal heat thrummed through her veins and liquid fire pooled in her core, dripping past her sensitive lower lips and down her inner thighs.

Luna began to whine for more, her body beginning to crave release from the growing inferno in her belly. She mewled with impatience as his hands rubbed and stroked along her back, turning her muscles into putty and ensuring she couldn't even muster the strength to move and thrash like she wanted to.

Just like Hermione, he made her helpless with his touch alone, and the concept of Harry Potter began to cement itself in her mind as 'Master,' just as she had done with her Mistress.

As his hands massaged her legs, she felt a new wave of her own arousal soak her entire pubic region, leaving her skin soaked and glistening.

Harry's mesmeric voice once again registered in her mind. "Don't you feel good, my little Moonbeam? Does it make you wet, to feel my touch against your skin? Do you want me to show you how to feel even better?"

His voice made her feel warm and indulgent, and she felt her head nodding before he had finished speaking, her body too relaxed to disagree with the one who had elevated her to this higher state of existence.

His pleased smile appeared in front of her face, making her heart flutter with pleasure for having pleased him. Their lips met once more, and Luna moaned delightedly into his mouth as he once again began to map the inside of her mouth, tasting and enjoying the addictive flavor of him.

"I am going to release you, my little Moonbeam, okay? When I do, I want you to sit up, and then come over and sit on my lap facing me, yes?"

Luna, far too entranced to deny him, cooed softly in acceptance, and felt the vines release her limbs.

For a moment, she could only lie there in a languorous stupor, the massage having robbed her of the energy that always seemed to be present during her lovemaking sessions. This experience had been unique in that it was not simply a carnal release but a steady stream of pleasure assaulting her from the beginning.

Mustering her remaining willpower, Luna pulled herself into a sitting position, swinging her long, smooth and slick legs over to side of the table and gazing down at her weeping core. Her hand briefly drifted down to trace her puffy sex-lips, coating her digits in clear, warm cum.

Gazing absently at the hand tempting her, it was suddenly taken in the warm grasp of Harry's own hand. Her eyes met his own, and she instantly sank into a haze as the dilated onyxes captured hers. His hand dragged her own up to her mouth, grazing her slick fingers against her pale pink lips, coating them in a thin layer of her own arousal.

Hardly noticing her actions, her pink tongue darted out, capturing the sweet fluid and dragging it back into her mouth. Without breaking her gaze, Harry guided her fingers into the blonde's mouth, where she began to clean them off, humming at the flavor.

Releasing her hand, his arms moved under her armpits and encircled her back, lifting her up. Her legs instinctively wrapped around his waist while her arms did the same around his neck. Still in her induced hyper-relaxed state, Luna let her head rest against his neck on her arm, leaving her body hanging off him dependently.

Sounds of protest made themselves known as Hermione realized what was about to happen, but Luna, now deaf to any sounds not made by her benefactor, paid them no mind.

Luna felt her back meet a smooth surface, and lifted her head to gaze confusedly at Harry, who smiled at her as he settled her against the cool glass of the greenhouse wall. Settled by his reassuring presence, Luna felt her worries dissipate.

Harry's voice once again penetrated the thick, heady mist that had engulfed her thought process. "I'm going to fuck you now, my little Moonbeam. Are you ready?"

Luna smiled, her eyes wide and trusting, and nodded happily at him.

She felt her body lower a few inches, and then felt something prod her throbbing core. The touch of foreign flesh against her hot, wet sex only added fuel to the fire within her, and her shoulders bowed forward into Harry's as she felt him slide into her slick, welcoming sheathe.

A breathless, wanton moan was torn from her throat as am empty space she never knew she possessed within her was suddenly filled. Then, as he began to pull back out, the hollow feeling she experienced made her cry out and tighten her legs around his waist, willing him to fill her once again.

Harry began to increase his pace, drawing whimpers, cries, and delirious mewling from her as her mind was consumed with carnal delight as she was carried closer and closer to the precipice of rapture.

Her release came without warning. As she covered Harry's length with her warm, glistening release she keened in utter bliss. His harsh pounding continued through her orgasm, lengthening it and introducing her to multiple aftershocks as her now-hypersensitive core was subjected to his delicious machinations.

His panting came hot against the length of her neck as he thrust against her. Right as she felt the world shatter around her once again, she was driven harshly against the wall as his cock, the head lining up perfectly with her cervix, began to throb and swell rapidly. Multiple jets of achingly hot cum impacted against her slick, eager insides as her center frantically clenched and milked him for his hot seed.

Luna felt his lips trail along her neck, reaching the base and tracing the mark Hermione had left on her the first time they had become lovers.

His teeth, flashing suddenly, slashed down on the mark, instantly making Luna tense up, eyes dilating as her Master drove her to a third, mind-numbing orgasm.

As their panting subsided, Harry lowered her trembling form to the ground, where they collapsed onto each other, her head laying on his warm chest as her fingers absently stroked she slightly sweaty skin. The sound of Hermione's outraged struggles were drowned out by the affectionate words Harry whispered into Luna's hair, and the dreamy blonde began to purr, lacking the energy to overcome the euphoria currently suffusing her petite form, radiating from the comforting, viscous warmth that filled her insides.

As the other girl's protests grew though, Harry realized that he couldn't leave her there forever, and with a sigh, pulled out of Luna's tight, slick heat, causing her to cease her purring and look at him confusedly.

He reassured her with a warm smile; a smile that grew just a little wider upon recognizing that she had become dependent on his judgement just as she had been with Hermione earlier.

Accepting his comfort, Luna shifted off of Harry to lean against the wall so that she had an unimpeded view of Harry approaching Hermione. As she gazed at her mistress, who was now glaring at her Master with narrowed eyes, Luna swept her pretty pink tongue across her lips once again as she settled into a comfortable position to watch the proceedings.

Harry began circling Hermione again, caressing her body, letting his hands glide tantalizingly around her breasts, up and down her arms, and up the line of her spine, making her back arch against her will.

Hermione's eyes, dark and feral, bore daggers into Harry as he continued teasing her. Muffled snarls and growls tried to make their way past the vine in her mouth, but only managed to demonstrate just how pitifully trapped she was.

Harry, once again in front of Hermione, let his hands rest on her stomach, the rough palms of his hands on her smooth, heated skin making her pant. Leaning forward, Hermione's eyes involuntarily closed as his lips left ghostly trails of fire across her throat and up the line of her jugular vein, nipping playfully at her pulse point. Her legs began to rub against each other as waves of heat fogged her mind and surrounded her body in a lusty haze.

As Harry continued to bite and suck on her neck, Hermione's head tipped backwards, offering up the slender column of pale flesh to his mercy. Continuing to possessively bruise and mar his lover's neck, Harry glanced back towards Luna to see her avidly pleasuring herself as she viewed his domination of her former-mistress with rapturous wonder.

He returned his attention to Hermione, beginning to aggressively suck on her pulse point, determined to leave a spectacular, dark bruise. His hands began to slip down from her stomach to the hot, wet flesh of Hermione's center. A mental nudge removed the vine from her mouth and instantly had the vines encircling her legs pull them apart, making a tortured hiss escape her as the cool night air assaulted her blazing heat.

Calloused fingers began to run up and down her inner thighs, parting the thick coat of transparent, warm cum to slide towards where her legs met her hips, avoiding the fleshy, twitching mound even as Hermione began to thrash and squirm, desperate for his touch.

His lips withdrew from her pulse, noting the large, prominent purple mark left there with a distinct sense of triumph. Letting her head fall back down, Hermione's eyes, fogged over in clear desire, met his own, this time devoid of a glare.

Her voice, hoarse and throaty, implored him; "Harry….please, fuck me already."

His intense gaze captured her own, the force of it enrapturing her consciousness and not letting her look away. "If I do," he saw lowly, "You will submit to me. Luna is ours, but you are both mine. You became mine the second you brought me here."

Rebellion sparked within her eyes, before it was once again overtaken by ecstasy as two of his fingers suddenly plunged into her needy heat. "Yes! Yes! I understand, now fuck me Harry!" Hermione cried out, incapable of further defiance as pleasure lanced throughout her body, making her twist and writhe.

Her body was suddenly weightless as the vines dropped her, before her shivering form was enveloped in Harry's strong grasp.

His tongue traced a circle around an unmarred, perfectly pale spot where her shoulder met her neck – almost exactly where they both had marked Luna. "When you cum, I am going to bite you here, and you will be marked mine forever, 'Mione," Harry informed her, sending a shudder throughout her body as it anticipated the painful gratification such an act would provide.

Her blazing heat was suddenly invaded by his heated length, making her cry out in delight as she experienced relief paired with an insatiable craving for further bliss. She began to savagely impale herself onto his hard length, screaming and howling as she indulged herself with the depths of her carnal delight.

Harry matched her pace, thrusting and plunging himself into her slick, clenching heat as he layered bites and nips along her collarbone, peppering her upper body with varying shades of possessive bruises, making sure to track the progress of her release to time his claim on her perfectly.

It didn't take long, Hermione's savage pace combined with the teasing she had already received ensured she was not going to last more than a short while, and as he felt the first fluttering of her core, he began to push even harder, flipping them over so that she was on her hands and knees.

Hermione's cried began to devolve into croaked moans and whimpers as her throat began to protest her caterwauling. As Harry's lips began to once again trace the untouched spot on her neck, Hermione felt a shiver of desire course through her.

When he nipped her lightly – not enough to even bruise – her arms gave out.

Their brutal coupling continued until Hermione finally could not take it anymore, and her core seized Harry's cock in an unbreakable vicegrip, clenching him and demanding his seed. Intent on fully dominating her, Harry obliged, filling her with searing heat and making her scream her delight into the night air.

Through the haze of ecstasy, Hermione registered Harry's lips leaving her neck, before his teeth slashed down, breaking skin harshly enough to scar, marking her like Luna had been.

Her entire body froze, her eyes wide and glassy and her mouth opened in a silent scream as the entire world stopped around her in the single most intense moment of her lifetime.

Quickly coming out of it, Hermione only faintly recognized her core continue to milk Harry's cock until her womb was filled with his liquid heat. She only barely acknowledge when he slipped her into a robe and picked her up bridal-style. When they arrived back at the Gryffindor dormitories, she didn't even register the fact that Luna had followed them both until she snuggled into her side as they all lay under the covers.

When she finally returned to reality, Hermione only took a few moments to process the entire night before a wide, beatific smile split her face before she tugged her pet into her side, sighing happily at the extra heat before she hugged her master's arm against her and settled into a peaceful slumber.

My apologies for leaving this last chapter off for so long. I blame laziness, the fact that I can only write these late at night, and the fact that I have to wake up at 5am every weekday for school.

At any rate, I hope you all enjoyed my first smut-fic! Like and leave a review for future endeavors. I do take requests for pairings and situations, so if you have an idea you'd like to see made, send me a PM and if I like the idea myself I may just write it out.

In addition, if anyone out there wants to use the Somnium Vitis plant concept in a story of their own, then I would be fine with that happening so long as I am asked first.

Fare Thee Well, everyone, and have a pleasant afterglow.

Forever Writing,
