Revenge and Redemption

~oOo~

Nymphadora Tonks lit her second cigarette and took a deep drag. Her hands hadn't stopped trembling. She let out the smoke to curl and twist in the cold night of Scotland.

Luna was still in the Safe House, still unconscious, still hurt. The unassuming cottage – property of the late Dumbledore, now a Safe House for the Order – lit the night through its windows. Tonks bit her lower lip hard, wishing to get revenge, if not from the Death Eaters that had done that to Luna, then from herself for not being able to protect her. She fisted her free hand until she felt her nails biting her flesh.

Fuck.

Luna had spent two months on Malfoy manor. Tonks had been there when Harry, Hermione and Ron had taken the prisoners to Shell Cottage – had been there to take Luna to this place and watched her be put on an induced coma.

But she should've woken up by now. Unfortunately, it'd been a week already, and Luna was still unconscious.

Tonks wanted to scream in rage, but she didn't. So instead, she took another furious drag and poisoned her lungs with vicious joy. The smoke burnt her insides, and she took a dark pleasure holding it in longer than usual, longer than necessary... long enough to punish herself.

Luna had been raped.

There was evidence... too much evidence.

Tonks had sworn to both Luna and her father that she would protect the girl when she became a member of the Order of the Phoenix. Tonks believed fiercely that she would always be there for her.

And yet...

Those sick fucks had raped her. Kidnapped her, imprisoned her, and violated her. Her sweet, sweet Luna.

Tonks's rage turned to a sob that threatened to choke her, but she heard a loud crack thirty feetinto the night and held her breath. She kept herself still and quiet as she'd been trained. She wouldn't have noticed the man advancing towards her if she hadn't recognised his scent – a deep, manly scent; as deep and masculine as his voice, and then – tobacco and herbs.

She shivered, tried to take another drag, noticed the fag was put out and lit it again using her wand. She filled her lungs with poison once more and exhaled the hot smoke into the night.

She turned her head to glare at the man.

"You shouldn't be here," she said in a raspy voice.

"I was kicked out of Hell and told to go suffer elsewhere," deadpanned Severus Snape's velvet bass. Tonks couldn't help snickering, though it soon turned into an unpleasant laugh. Bitter tears threatened to spill out of her eyes, but she kept them in check.

"If I had any doubt you've got Black blood in your veins, those barks would've been enough to enlighten me, Nymphadora."

Tonks huffed, made a show of spatting lazily on the floor and took a drag with all the impertinence she could muster.

"Don't call me Nymphadora," she said flatly.

"Insolent brat," he answered, but there was fondness in his voice, and she knew it. She felt a lump in her throat and had to swallow twice before speaking.

"She's inside."

Her words came out as a whisper. She saw Snape nodding, then he placed a hand on her shoulder – so warm, so large – and silently went towards the main entrance.

Once he was inside the Safe House, Tonks let out a shaky breath and squashed the fag-end with her dragonhide boot.

~oOo~

She found Snape bent over Luna, frowning. The girl lay on her bed, still as a statue, and Tonks felt the need to take another cigarette. But no, not inside, she couldn't.

Snape spilt three drops of something that smelt minty on his fingers and started rubbing the potion on Luna's front and temples. Tonks wetted her lips. It always fascinated her how gentle and dexterous those callous hands could be.

"How is she?" Tonks croaked. It made her nauseous looking at Luna's unconscious form.

Severus paused his ministrations and looked at her, face impassive, eyes as dark as hopelessness.

"She seems stable," he calmly answered. Tonks felt the need to shout at him in frustration, but Severus's rich bass spoke again. "I've done everything I could, Dora."

She knew that, of course. She'd been there when Severus took care of Luna. He always did everything he could, and what he could do was often remarkable. Not that the other Order members knew about his true allegiance. She felt tears rising, and she faced the window to gain some privacy. Suddenly, she heard some stirring and turned back in time to watch Snape widen his eyes and grab Luna's shoulder.

"Miss Lovegood!"

Luna's face twisted in fear, and Snape flinched away from her. Tonks' heart broke.

"You're safe, Luna." The girl's face relaxed a fraction when she saw Tonks, but she looked at Severus dubiously. Tonks swallowed. "He's in our side. Always has been. He's undercover, you understand."

Luna didn't seem very convinced but looked at Tonks with those big, big blue eyes of hers full of trust and gentle love.

Trust and love she didn't deserve anymore.

Tonks felt like crying and hurting herself in punishment. Instead, she approached the girl lying on the bed. She knelt on the floor and took Luna in her arms. She smelled like roses and jasmine.

"Speak to me, sweetie. How do you feel?"

Luna didn't answer but burrowed her head on Tonks' chest. Her heartbeat grew faster as if wanting to reach out. Feeling lost, she looked up and met Severus's eyes.

He stood perfectly still, like some kind of royal guard. As much as he was good at concealing his emotions, Tonks could identify both the relief and hurt in his face. His eyes flicked with some mix of feelings – vulnerability and something more complex that eluded Tonks. Severus averted his gaze.

Tonks closed her eyes tight and kissed Luna's beautiful blond hair. The girl sighed and hugged her more tightly.

Severus cleared his throat.

"I need to return to Hogwarts."

He stepped towards the door, and Tonks's heart throbbed painfully.

"Severus, wait."

He stopped.

"Thank you," she murmured.

Snape looked back over his shoulder and gave a court nod.

"If she needs me again, write to me. You know how."

Tonks nodded, but his eyes were back facing away from her, and he was already crossing the door.

"Be safe," she whispered, though he probably couldn't hear her anymore.

~oOo~

Five days passed, and Luna's health seemed to improve significantly. The girl was currently outside strolling among the flowers and herbs of the garden. Tonks had confined her to the cottage and its grounds while the girl healed. It was for her own safety, she knew, but...

Tonks looked out of the window, watching the gentle breeze that played with Luna's golden hair. She looked like the fair princess of a fairy tale. A medieval beauty, trapped in her tower. Tonks felt an imperious need to kiss those rosy lips of hers. She sighed and closed her eyes. She had to remember Luna was traumatised. She couldn't impose that on her, no matter how many times they'd kissed each other already.

Cradle-snatcher.

But she hadn't done anything Luna didn't want to and asked for. Right?

Right, she thought and sighed again louder. She liked to believe she wouldn't have given in if there wasn't a war raging around them, threatening to reap their lives short.

Right.

Speaking of grim reapers. Why the hell didn't she have any news from Severus? She glanced at the magical ring that served as direct communication between them. The messages had to be short since they appeared written inside the seemingly mundane jewellery – but she knew for a fact that Harry, Ron and Hermione would be trying to break into Gringotts soon if they hadn't already. She was becoming restless with the lack of news from Severus. She had no doubt their next destination would be Hogwarts. How would Severus handle it?

She hoped they wouldn't have to confront each other. Her stomach turned into knots.

Suddenly, her ring heated, and she took it out hurriedly.

May I come tonight?

Tonks' heart fluttered, and she smiled mischievously while she replied,

You will. If you're a good boy.

Insufferable brat, came his response.

She laughed with mirth, feeling light-headed, and went out to the garden to join Luna.

Tonight, the war could go fuck itself.

~oOo~

At 8 PM, Tonks heard knocks on the front door and went to open it hastily. Snape stood somewhat awkwardly. He cleared his throat.

"I've brought potions," he said, "for Miss Lovegood."

Tonks felt a warmth spread through her chest and reach her cheeks.

"Thanks, Sev. That's really thoughtful."

His face remained impassive, but his high cheeks tinged with pink. Tonks concealed her smile.

"Please, do come in. Tea?"

Snape sneered. Tonks had a flashback of a certain strict Hogwarts professor.

"At this hour?"

Tonks smirked mischievously.

"We could have dinner if you'd prefer."

Snape huffed and tried to conceal his amusement.

"Minx. How do you make a mundane invitation sound like an improper one?"

She was about to reply when she noticed Luna standing in the doorway to the kitchen, dressed only on her almost see-through white nightgown. Judging by Snape's rigid posture beside her, he had seen her too. Tonks swallowed.

"Sweetie pie. I thought you were in bed."

Luna had the dreamiest smile on her lips, and she cocked her head. Her beautiful blond tresses cascaded like a curtain of silk. They looked so smooth, and Tonks's hand twitched with the need to comb it with her fingers.

"I'm not sleepy," Luna said calmly. "Dinner? I'm hungry."

Snape made a choking sound, and Tonks repressed a nervous giggle.

~oOo~

"So what does this one do, sir?" Luna asked.

They had finished dining, and they were in the bedroom that had become Luna's. The girl was sitting on her bed and looking at the varied flasks and potions lying next to her.

Tonks switched her weight from one foot to the other. She had become used to sleeping next to Luna in that same bed, had become used to holding her and kissing her tears dry when the girl woke up from a nightmare. But somehow, sharing this space with both her and Severus made it much more intimate than before. Tonks wetted her lips as Snape took the flask gently from Luna's delicate hands and manipulated it dexterously.

"This one is a tonic lotion," he murmured, and hearing his voice, Tonks felt a pleasant shiver down her spine. "It helps deal with all types of muscular aches."

Luna's head perked up. She seemed flustered.

"What does it do exactly? Sir?"

Severus cleared his throat.

"It relaxes the muscles and heals the tissues. You may feel a soothing warmth when you apply it."

Tonks had a sudden vision – Luna, naked and splayed on the bed, bound and meek as a lamb, and Severus applying that very lotion on her, with all the patience and gentle authority she knew he was capable of. She felt herself getting wet, and she knew she must be blushing.

She was a Hufflepuff, not a Gryffindor, but she dared anyway.

"Luna, sweetie. Why don't you lie back and let us massage you? You've been through a lot. And I think we owe it to you. We were supposed to protect you, and we failed, after all."

Luna frowned in confusion and looked at her owlishly. Tonks was already regretting her words. But then Luna shrugged and smiled gently.

"All right. But it's OK, you don't owe me anything. You couldn't possibly protect us all."

Tonks felt guilty anyway but nodded and approached Luna, unable to look at Snape. She knew he must be shocked into silence. She cleared her throat.

"Before we begin, Luna," she said, voice tense with nerves, "I'd like you to know that we can stop any time you want. Just say no, and we'll stop. You know that, right?"

The girl smiled dreamily and locked her gaze with Tonks's.

"I trust you, sis."

Tonks's cheeks were ablaze. Luna'd taken the habit of calling her sis just like she had taken the habit to call her sweetie. But no one else knew, and it sounded strangely indecent in the current context.

"You can trust Severus too, Luna."

The girl fixed her gaze on him. Tonks knew a lesser man would've fidgeted, but he didn't.

Snape's smooth bass rumbled quietly. "I give my word, Miss Lovegood, that I will not hurt you. I won't touch you if you don't desire it, and if you wish it, I will leave."

Luna blinked and looked at Tonks seriously, then returned her gaze to Severus.

"No. If sis trusts you, then I trust you, Professor Snape."

Tonks's cheeks became even hotter, and she could feel Severus's awkwardness rolling off him in waves. He cleared his throat.

"Very well."

Luna nodded, averting her eyes to the floor and blushed. She actually blushed! She looked like the cutest girl on earth. Tonks's breath hitched, and her heart started beating faster. She felt entranced.

"Severus, if you don't mind…"

"Hmm?"

His rumbling hum sent another wave of tingles down her neck.

"What about you massage her body, and I her head?"

Snape looked dubious and glanced at Luna.

"Wouldn't it be better the other way around?"

They both looked at the girl, who was currently lying on her stomach. Luna opened her pretty, dreamy eyes.

"I'm OK with having your hands on my body, sir," she said timidly and then blushed a deeper red. Snape seemed embarrassed, and Tonks held back a nervous giggle. It could become such a kinky sex scene if not for Luna's past experiences with men.

Not men, she thought bitterly. Swine.

Slowly and gently, Tonks lifted Luna's white nightgown, and with her collaboration, the garment was swiftly discarded to the floor, leaving her in her underwear.

Tonks climbed up the bed and sat cross-legged next to Luna's head. She then coaxed the girl into leaning her cheek on the crossing of Tonks's legs, so her head and hair were free to be played with. Quietly, Severus sat on the edge, careful not to touch Luna, and poured the tonic potion on his palms, rubbing them together.

His hands were mesmerising. Tonks felt warm all over and started combing Luna's hair with her fingers carefully. But her eyes constantly drifted to Severus's hands, currently spread on Luna's back and dexterously working on her muscles – Merlin's pants she was petite, and his hands were large and why was that turning her on so much?

She was painfully aware of how wet she was and silently prayed Luna couldn't identify the smell. In fact, now it didn't seem such a good idea to sit cross-legged with Luna's face so close to her core. Tonks's heart beat faster, and she licked her lips. There were, what? Five inches between Luna's front and her pussy? It would take so little to –

She looked at Severus, troubled. His hands were on Luna, but his gaze was fixed on the very spot she'd been thinking about. She swallowed, nervous as hell, and looked down to watch Luna, eyes closed and lips parted, quiet moans escaping her mouth every time Severus's knuckles freed a sore spot. Tonks took a shaky breath. It'd be so easy to simply give in and – and show Luna how much pleasure her body could bring her; to erase the memory of those filthy swine and the pain they'd inflicted her by pleasuring Luna like the princess she was and –

One look at Snape, though, and it was as if reality had slapped her.

"Severus?" His name came to her lips instinctively. His Adam's apple rose and fell as he swallowed.

"We should..."

Severus didn't finish his sentence because he didn't need to, and Tonks could hear the words as if he'd said them aloud.

...Slow down.

Tonks wet her lips nervously. At least they were on the same page.

She wasn't sure when or even why they'd began seeking each other for physical pleasure. Tonks only knew it had grown into a relationship neither dared to define, but she knew that look in his eye and the way his body tensed.

Snape was hesitant. Well, first things first. She cast a warming spell on Luna and lifted her chin with gentle fingers.

"Luna, sweetie. Could you give us a second, please?"

The girl nodded, already sleepy, it seemed, and Tonks caressed her exposed cheek before gesturing Severus to follow her outside. Once on the corridor, she cast a Muffliato.

"It bothers you," she murmured.

Snape raised an eyebrow.

"And it doesn't bother you?"

She knew what he was talking about. She crossed her arms.

"It might help her."

Severus snorted and crossed his own arms.

"In what? Traumatising her further?"

Tonks bit her lower lip with anger, then released it.

"Or maybe the opposite."

Snape sneered.

"Pray, tell me how being manhandled by a man with the dark mark on his armis going to help her overcome the trauma of two months of rape and utter powerlessness."

Tonks averted her gaze, then looked at him again, defiantly.

"Well, precisely, Sev. By having the power to end everything."

Severus growled.

"Are you daft, woman? It's been only two weeks since she was in Malfoy Manor!"

Tonks felt her own temper rising.

"And it could be only two weeks until one of us drops dead, Sev! What if they come this morning? What about that?"

But Severus didn't take the bait.

"They already came for Luna."

"And they could come again! They could take her again! And they could take you!" she exclaimed, shuddering, then tears welled up in her eyes, so she put a hand on them in a futile attempt to hide it. When she felt she'd controlled the outburst and opened her eyes, she found Severus's attitude had mellowed. His arms lied on his sides, dead. He hesitated, then he lifted them to embrace her. Tonks had a hard time squashing the sob that threatened to come out.

"Perhaps we're not in the best mindset, Dora," his voice rumbled, and she burrowed her head on his chest. She sniffled but didn't answer. Severus grabbed her shoulders and pushed her gently to look at her. His eyes were two warm pools of black ink.

"Let's return to Miss Lovegood. We may continue the massage if she wants" Here, he lifted an eyebrow. "If she can obtain sexual gratification and only if she wants it, then we must be gentle... vanilla."

"And if not?" Tonks asked.

"Then we leave her alone to sleep and continue in the other bedroom."

Sometimes she felt truly peeved when he talked in that oh-so-reasonable-and-sensible tone, but sometimes, like tonight, it made her feel calm and soothed.

"Will you be Daddy?" Tonks quipped despite her watery smile.

Severus blushed faintly.

"With Miss Lovegood?"

Her grin turned somewhat cheeky.

"She already calls me "sis"."

Snape's blush deepened.

"I'm not sure I'm going to be able to enter the Domspace tonight, Dora, frankly. Besides, haven't we agreed to go vanilla tonight?"

Tonks let out a shaky breath.

"I need the rules, Severus."

He nodded. He understood, she knew.

"Very well. But I don't have the energy for a complex scene. Let's adopt our dynamic, not too overtly, and see how she responds to that first. She is our focus. If I cannot enter Domspace, I will tell you."

Again, Tonks buried her face on Severus's chest. "Deal," she murmured.

"Which role-play would we do with you as the Dom?"

She blushed furiously, and Severus chuckled. "The tyrannical empress and the loyal captain of her guard, I presume."

Always spot on. Tonks was unable to look him in the eye.

Severus smirked. "And the delicate, virgin girl freshly picked to be the empress's concubine?"

Oh Gods. She hadn't thought about Luna yet, and already Severus knew what her kink would be.

"Too elaborate to use it tonight, though," she murmured.

Severus's smirk relaxed into a faint smile. "I'm partial to the old man treatment, and you know it."

Tonks' cheeks were hot as hell, but she still barked a laugh. "The impudent wench and her stand-in professor? Luna could be the timid teacher's pet objecting to it."

Snape huffed, amused. "Why not? I'm still not sure she'll agree to any of this, though."

Tonks was about to reply when suddenly, the door cracked open, and Luna appeared behind it, utterly naked, eyes sleepy. Her pubic hair was dark blond, soft and pretty. It made Tonks want to rub it and pet it like she would a kitten. But, ashamed of her thoughts, she snapped her eyes up, trying to conceal the fact she'd been staring.

"Sorry to interrupt," Luna murmured dreamily. "I need to use the loo."

Still stunned, they moved to let her pass, and she bounced to the bathroom while humming a random melody. She gave off such strong Heidi vibes it made Tonks want to run after her and hold her in her arms – kiss her cheeks, her lips, those delightfully perky breasts –

Luna stopped midway and turned towards them. Tonks knew her whole face must be as red as a ripe tomato.

"By the way. I like the last scenario best," she said calmly as if she'd just talked about her preference for nail polish. Then she resumed walking – bouncing – towards the bathroom.

Shocked, Tonks looked at Snape to find him pink-faced and mouth agape. She burst out laughing.

"I always was pants at Muffliato," she conceded.

~oOo~

An hour later, Tonks was amazed Luna hadn't backed out of what was the most unlikely situation.

She and Severus had given her a brief introduction to safe words, ensuring the girl that they would slow down if she said 'yellow' or could back out at any time by saying the word 'red'. The bedroom had been transfigured into a generic classroom. During which Luna assured them both that she very much wanted to take part. Tonks was pleased that Luna was so willing to play along.

Tonks mentally chastised herself, knowing she should concentrate on her role.

She popped her bubble-gum and started tapping her feet annoyingly as she sprawled on her chair. Her arms crossed, and she sighed dramatically.

Snape droned on about basic Arithmancy – he was never able to role-play with Potions or DADA – and Luna sat close to the makeshift teacher's desk, her good girl attitude, so spot-on Tonks felt her nether parts ablaze. She imagined Luna kneeling in front of her, lapping at her pussy, while Tonks grabbed her golden locks and held her in place with imperious force.

Nice. Not tonight, though.

Snape asked a question she ignoredand promptly, Luna waved her hand up in the air.

Severus's deep bass rumbled. "Yes, my dear?"

He hadn't called her Miss Lovegood in all the scene. He also never called her Miss Tonks when they recreated a teacher-student scenario.

"I don't understand the lesson properly, sir. Could you explain it again?"

It was Tonks's turn. She snorted rudely.

"Rubbish. You're a Ravenclaw. Stop being such a teacher's pet, Miss Prim."

Luna didn't react, didn't look back, but Snape turned his intimidating glare towards her. They locked their gaze for an intense moment. The thrill of the fight, the power struggle, left her panting and wet.

"Is that so?" Snape's velvety voice was deceptively calm but full of threat. "Detention, young lady."

Tonks smirked cheekily.

"I know what you're thinking, old man. But you won't make me suck your cock like Miss Prim here."

Luna made the cutest little gasp. She was good. Tonks's smirk widened into a grin. Snape approached Luna with deliberate steps – he was holding himself stiffly, with all the authority he was capable of. Tonks felt a shiver down her spine. Once upon a time, she had feared that man's wrath.

Now, it was all part of an exciting power play.

Severus rose his hand and placed it on Luna's head, petting her as if he owned her. Luna leaned into the touch with natural obedience. Tonks felt her wetness slipping down her thighs, and she licked her lips, mesmerised by the show. However, her eyes were still locked to Severus's.

"She is indeed a good girl," he rumbled darkly. "And soon, I'll tame you into one too, insolent brat."

Tonks's cheeks hurt from grinning malevolently.

"You wish, old man," she said darkly, and her voice came out raspy and menacing. She saw a flicker of something on Snape's eyes – weakness? Fear? Anticipation? It was a crack on his armour, and Tonks went for the jugular, knowing it was time for her to take the lead. She stood up swiftly, wand in hand and pointed at Severus.

"What the - ?"

"Expelliarmus! Locomotor Mortis!"

Snape's legs bound together, and he lost his balance. He'd have fallen flat on his face if not for Luna's hold, who'd stood up with a swiftness that won Tonks's admiration. Tonks caught his wand in the air and smirked evilly. She felt high on her success.

"Well, well, Professor. Unfortunately, we stumbled upon a problematic situation, didn't we?"

Snape opened his mouth to retort, but Tonks was faster, and suddenly he was bound and gagged. Luna still held him. She looked frightened but had her brow furrowed.

"You shouldn't do that to the professor," Luna said softly.

Tonks approached them with the cockiest swagger ever. She sunk her fingers on Luna's silky blond hair and grabbed the back of her head, gently but possessively. Luna's big, puppy eyes were so limpid and cute, her demeanour so soft, Tonks didn't resist the urge to kiss her rosy lips. At first, Luna didn't respond, but then she opened her lips, and Tonks took it as an invitation to claim her mouth with her tongue.

She was so warm. So pliant. Tonks growled. She felt a drop of her juices running down her thigh; she was so turned on that her core pulsed. Snape's own angry growl turned her attention back to the man. She smirked cheekily.

"What's the matter, Professor? Feeling left out?"

Snape glared, proud and defiant, and Tonks felt the imperious desire to just smother him with her cunt. She had to remember she couldn't just start manhandling him roughly, though she very much wanted to.

"I'm going to lift you and bind you to your desk, you lecherous old man. It's high time you were used asa sex toy. What, what's that look? You thought I wasn't aware of what you made Miss Prim do on those extra lessons? You thought you'd never have to pay for it?"

Snape snorted and rose an eyebrow as if to say, "jealous?" and his defiance shot a pleasant zap downto her pussy. Grinning madly, she grabbed Snape's chin roughly and magicked his gag away.

"Well, old man? Are you ready for atonement?"

"Yes," he spat, making his enthusiastic consent sound like a fuck you. It was enough to push Tonks to almost break out of character and roar in laughter. Luna did allow herself to smirk for a bit, but it didn't last, and the meekness returned to her face.

"And you, Miss Prim?"

Luna only smiled sweetly.

"Nice," she said darkly. "Well, nice."

She muttered the necessary spells to lift Severus and bind him to the teacher's desk. She made sure he was comfortable, though she masqueraded it as an intimidatory display.

"Say you're sorry, you old fuck."

Snape snorted and rolled his eyes. Tonks grabbed his locks painfully.

"What. Was it nice using her as a cum bucket? To know you could stuff your cock down her throat and make her swallow your sticky mess? Was it nice, coating her womb with your spunk and breeding her like cattle?"

Snape's eyes darkened with lust. Oh, she knew very well which dirty talk to use. She held his hair more tightly and placed her lips on his ear.

"But you know what, old man?" she whispered, and she felt Snape shivering. She smirked. "I don't take it kindly when people put their filthy paws on my toys."

She shot a piercing glare to Luna, who panted noticeably and had a pretty blush on her cheeks.

"Come here, Miss Prim. Now!" she growled. The girl obeyed swiftly, and in seconds, she stood beside her.

"Good girl," Tonks cooed, her free hand finding its way on Luna's locks and combing them with dangerous gentleness. "Now. Did the Professor touch you inappropriately, Bunny?"

Luna blushed at the pet name and fixed her eyes on the floor, nodding mutely.

Tonks glared at Snape, and for the first time since they started, Severus's eyes showed weariness.

"Did he make you lap at his penis?"

Luna blushed deeper and nodded.

"Did he put it in your mouth?"

Another nod.

"Make you suck it and choke on it? Twirl your tongue around its head?"

"Yes." Her voice was feeble and creaked, and she was panting hard.

"And did you like the way his cock felt in your mouth?"

Luna flushed red again.

"Yes, miss."

Tonks felt intense relief and rejoiced inwardly in Luna's choice of name – a slip that pleased her very much.

"Did he put his cock inside your pussy?" she demanded, subtly guaging just how far Luna was willing to go.

Luna licked her lips. "No, miss."

Oh. Now that's interesting.

"So, he didn't, hmm?"

Luna shook her head, her eyes still fixed on the floor.

"Well, well, old man," she said, returning her attention to Severus. "It seems you're slyer than you look."

Snape frowned but didn't move in any other way.

"Still, you deserve a punishment for what you did to her." She inclined her head once more to whisper to his ear. "An eye for an eye, Professor." she stood up straight. "Miss Prim?"

Luna shuddered visibly. "Y-yes?"

"Would you like to get revenge?"

Luna cocked her head. "Y-yes?"

"Take off your underwear, but leave the rest on. Keep the shirt unbuttoned."

She looked like she'd like to object, but she nodded silently and started unfastening her clothes.

Tonks watched carefully as Luna slid her panties down her slender legs to pool at her feet.

"Good girl," she praised and turned her attention towards Snape. "Now, old man, you'll learn how it feels to surrender your breath for another's pleasure. Miss Prim," she called her and commanded Luna's attention. "You're going to get on that desk, face the geezer's feet, kneel so your pussy's above his mouth and sit on his face. You heard me?"

Luna looked hesitantly at Snape. Tonks followed her gaze, and she inhaled sharply.

Finally.

His eyes were full of vulnerability. He'd given up fighting and was now submitting fully.

"You want her pussy, don't you, old man?"

"Yes," he whispered. Luna's eyes widened.

"You've heard, Miss Prim," Tonks said darkly. "The old fuck's ready to accept his punishment."

She held Luna from her waist, helped her get on the desk and placed her above Severus's face. Her pretty, wet cunt hovered inches apart from his mouth. His Adam's apple rose and fell, and he looked at Tonks like a lamb about to be eaten by the wolf. She grinned, full of malicious pleasure.

"You better lap at her pussy like you worship her."

She pressed her hands downwards, lightly, and Luna closed the distance that kept her from Severus's lips. Luna didn't seem to dare press too much, but soon she started mewling in the cutest way, rubbing her sloppy folds against Severus' lips and chin, arching her back like a cat in heat and bending her upper body until her bouncing breasts brushed against Severus's frock coat, making her moan.

Tonks kept her hands on Luna's waist, steadying her and making sure she didn't truly smother Snape. She had such a beautiful hourglass shape, so womanly despite her age that Tonks followed her urge to start stroking her back up and down in silent praise.

She looked below to find a very red-faced Severus, so she gently coaxed Luna to go up and let him breathe properly for a moment.

"How does she taste, old man?"

Snape seemed too lost in subspace to answer. She grabbed his chin and yanked it up towards her. That got her a reaction.

"Divine."

Yeah, really far gone. She smirked.

"See? You can be the good guy," she cooed and chuckled when his eyes darkened in pleasure. "Now, keep lapping at her sweet little cunt, and I may reward you."

Luna gasped when her folds made contact with his lips once more. She started working her lower body more insistently, and Tonks helped her. Luna's hips jerked, and she moaned lewdly, her movements more frenetic than before. Periodically, Tonks made sure Severus had breaks to breathe properly and asked him if he was still OK with it.

He always was, and she was so horny she had a hard time being patient and attending to Luna's and Severus's needs. She couldn't help it; she was so turned on she started rubbing her own dripping pussy against Severus's head. It wasn't much, but it provided some relief to her aching clit. Luna's sloppy folds coated Snape's lower face, and Tonks felt the urge to lap it off him, but she restrained herself.

Luna started panting and mewling and moaning continuously, her voice so sweet it made Tonks wild with lust. Unable to hold it any longer, she put her mouth on Luna's shoulder and sucked hard. The girl keened, and Tonks started biting her flesh, not too rough but enough to leave bruises and mark the pretty girl as hers.

Hers.

She felt a surge of possessive lust towards both the man bound to the desk and the girl trembling above him. She had had plans for this scene – plans she suddenly decided to change. Roughly, she held Luna's womanly hips and forced them three inches above Severus's mouth. The man gasped like a half-drowned man, his lower face coated in lubrication and glistening in the dim light.

"Please," he begged. His breathing was ragged, and Tonks felt the darkest side of her fill with dangerous lust.

"What do you want, old man?"

Snape closed his eyes in defeat, apparently unable to form words. He, the most dangerous of men, Voldemort's lieutenant and Dumbledore's double spy, gasping for air and begging for mercy.

Her mercy.

Tonks felt high with power and lust. "You'll pay for your sins, Death Eater," she rasped, her voice so dark and malicious she almost didn't recognise it as hers.

Snape's eyes opened, his smouldering gaze lustful and needy and desperate.

"Make me," he whispered hoarsely. "Make me pay."

Tonks grunted, feral instincts taking over her. She bared her teeth and bit the heavily clothed juncture between Severus's throat and shoulder hard. Hard enough to make him cry in pain despite all the layers that still covered him. Tonks's angry lust consumed her like fiendfyre, and roughly, she pushed Luna forward and climbed on the table. Then, with a muttered spell, she vanished her own underwear and looked down, pinning Snape down with her gaze, a cruel sneer grazing her lips.

"I'll smother you with my cunt, Death Eater scum, and I'll cum on your face while you struggle to breathe", she growled savagely. "Would you like that?"

"Fuck. Yes," he hissed. Tonks chuckled darkly. Luna seemed tense, but Tonks was too far gone now and decided to push for more.

"Miss Prim," she rasped, and Luna's whole body stood at attention. "I want you to turn over and lay face upon him. That's it. You can rest your head on his knees. Don't worry, he can't move."

Tonks watched appreciatively.

"Spread your legs, Bunny. Nice. That's it. You've got such a pretty pussy, you know? It makes me want to eat it raw."

Luna's face and chest were flushed pink, and she panted with her mouth half-open, open enough for her cute tongue to be visible.

Unable to restrain herself, Tonks lowered her hips with a grunt and assaulted Snape's mouth with her dripping folds, rubbing furiously and preventing him from breathing. She then lowered her upper half, put her weight on her elbows and spread Luna's pussy with her fingers. Tonks started sucking and lapping at her, tongue insistently pushing and rough handling her pretty little pearl. Luna began keening and moaning wildly, and Tonks could feel Severus convulsing below her – she rose her hips, just for half a minute, then sat on his face again, and he whimpered –

Luna's back arched impossibly up, and she wailed loudly, her body convulsing and trembling, and Tonks kept her tongue flat against Luna's clit, letting the girl ride it while chasing her pleasure. Luna let herself fall on Snape's body almost too soon, panting heavily and smiling like the cat that got the cream. Tonks growled, aroused beyond measure by the lewdly sprawled teenager and her naughty display – school uniform dishevelled, cunt glistening with pleasure, perky breasts proudly piercing the air –

She felt a tremble on her folds, and automatically she rose her hips. Snape coughed and spluttered, gasping for air in such a way Tonks wanted nothing more but to sit on his face again and press down viciously.

Still.

"Tell me what you want, you filthy scum?"

Snape took a few seconds to answer, but his words were firm when he rumbled, "More."

"Very well," Tonks said darkly, "But I warn you: I have no mercy for the likes of you, Death Eater swine."

She didn't let him have time to reply. She started rubbing her folds against him, roughly and cruelly, pushing and pressing and chasing her orgasm with no regard for his comfort. She was drunk with power and lust, the knowledge that she could kill him while she rode his face a potent aphrodisiac. A primal rush of depraved pleasure rushed through her veins, pushing her to dominate, to punish; she owned his life and could end it in a whim, in the most humiliating manner: smothered under her cunt and powerless to stop her, his painful struggle for life nothing more than a play for her, a means to her climax –

She came with a low, triumphant moan, her pleasure rushing through her limbs like electricity, her body convulsing and trembling with one of the strongest high of endorphins she'd ever experienced. She kept rubbing and pressing down, trying to draw out the pleasure. But as the high decreased, she suddenly worried she'd gone too far, and she rose her hips. Snape gasped and gulped for air, but his look was one of total submission and placid meekness as if the content of being used as an object. Tonks wet her lips.

Luna was still sprawled on him, her pretty eyes wide and awed. Tonks smirked tiredly and gestured with her head to indicate they should climb down. Luna obeyed quietly. Tonks was still panting, and Severus's breath was still painfully irregular. She approached him, grabbed his hair and yanked his head up, making his glistening chin stand out.

"Now, old man," she growled while lapping at the juices that coated his Adam's apple. "You've behaved well for the scum you are. Exceptionally well," she murmured against his skin, and he whined pathetically. "I think you've earned a reward. What do you say, hmm? Do you think you deserve a reward?"

Snape closed his eyes in total surrender.

"Yes," he whispered. Tonks grinned evilly.

"Well then," she rasped, grabbing Snape's rock-hard erection through his clothes. "You tried to take advantage of Miss Prim here while avoiding unwanted pregnancy, didn't you? It would cause a scandal if she'd got pregnant, right?"

Tonks hopped again to the table and straddled Snape. He rose his head in alarm. Tonks smirked like the Devil. "You better not come inside me, then, or else I'll tell the Headmaster you raped me. I bet your balls are blue for holding so much cum for us, old man."

Snape groaned and let his head fall against the table while Tonks made quick work of freeing his dick.

"Let's see for how long you're able to hold it without spilling like a teenage boy, Professor."

She aligned her cunt with his dick and impaled herself slowly, moaning in pleasure at the wonderful stretch. His cock was thick and hard, red-hot iron wrapped in silk. She angled her hips so she could rub her clit against his abdomen and started rocking slowly, savouring every inch that went in and out of her, knowing he fought a lost war against her womb.

Snape groaned and panted, the air thick with the smell of sex and sweat.

"Miss Prim," she groaned, and Luna, once more, turned her mesmerised gaze towards her. "You'll agree with me the Professor's been very good for us, right? That he's earned his redemption?"

Lips half parted and eyes full of lust, Luna nodded with her head.

"You'll let your Professor play with your pretty breasts, won't you?"

Luna smirked naughtily, eyes alight with mischief. It was out of character, but that didn't stop Tonks groaning in lust. "Yes, miss," she said.

"Good girl," she rasped. "Straddle the old man and let him lick and suck at your nipples."

Luna did as was told, and quickly, Tonks's hand was caught between Luna's folds and Severus's upper stomach, rubbing the blonde's clit – or rather, letting the girl rub herself on her fingers. Tonks listened as the sounds of desperate kissing and sucking and lapping added to the sloppy sounds of her dripping cunt tormenting his cock.

"That's it, old man," she said evilly, "You're our toy thing now. You better not cum without my permission. I want to enjoy riding your cock for a long time. You're mine now," she growled possessively, and both Luna and Snape keened. Tonks chuckled darkly. "Yes, both of you; you're my sluts –"

Luna started jerking her hips with even more enthusiasm, like a jockey on her final sprint. "That's it, sweetheart," Tonks panted, "ride your pony like a good girl."

Luna's back arched for the second time, and her lips parted on a low, drawn-out moan, her arrhythmic movements rubbing her folds against Tonks's hand until she spent herself and fell on Severus like a trembling rag doll. It was so depraved, her tiny pink pussy leaking her juices on Snape's clothed chest, the man bound and unable to prevent them from using him for their pleasure.

Severus moaned. "Please," he gasped.

"Please what, old man?"

"Please, let me finish. Please let me cum!"

"Tut-tut, Professor. So unprofessional."

"Please!" he whined. "Please, I won't be able to –"

"You will," Tonks snarled. "You will control yourself, filthy scum!"

Snape wailed.

"Please!"

She chuckled darkly.

"So humiliating," she taunted. "What would your masters think of you if they saw you now, begging like a whore?"

Severus started sobbing, and Tonks's heart filled with dark, malevolent delight.

"You won't come until I do," she threatened cruelly. But she was already so turned on, rubbing and rocking and bouncing on him to dominate him, to crush him and own him and – she reached past Luna's spent body and bit Snape's throat hard, marking him as her possession, her plaything –

Soon she felt the second rush of endorphins exploding from her core and sweeping through her veins like a tidal wave. Tonks opened her lips and shouted piercing moans of satisfaction and triumph.

"Come!" she snarled. "Spill it. It's mine! You're mine! Yield to me!"

Snape groaned, and his hips jerked upwards, erratically, as much as his restraints let him. Then, on a silent cry, he suddenly stilled, and Tonks felt him spurt his hot, sticky seed inside her, much more abundant than usual. He let himself go limp, and still panting, Tonks whispered the spell to free him from his restraints. With another spell, the desk turned back into a large bed.

Utterly exhausted and pacified, Tonks looked at Luna and Severus, trying to gauge their state. Snape was panting, his eyes closed, and Luna had removed herself from his chest. Tonks let his penis slip out of her, stretched herself along Severus's length and started combing his hair. Finally, he cracked an eye open.

"Hey," Tonks said, feeling a bit awkward after the savage display earlier. "Are you two all right?"

Severus huffed and closed his eyes again, a naughty smirk on his lips.

"My, my, Nymphadora," he rumbled in his silky bass, "'coating her womb with your spunk and breeding her like cattle'?"

Luna giggled from the other side, and Tonks felt her cheeks heating. She was about to make some cutting remark when Luna's sweet voice beat her to it.

"I wouldn't mind playing studs and broodmares the next time."

Severus started roaring in laughter, and Tonks hid her blushing face with a groan. But, inside, she was glad to see Luna smile and jest and glow in post-coital bliss.

Her sweet, sweet Luna.

Tonks smiled and reached out to kiss Severus's and Luna's cheeks.
