Chapter 4
"DIFFINDO!" Harry shouted, channelling all of his magical energy at the dummy before him. A huge red arc shot out of his wand, slicing the head clean off the dummy in front of him before continuing and leaving a gash almost a foot deep in the stone wall behind it. Luna clapped her hands excitedly, "very good master," she purred, "you're certainly getting far more powerful by the day." Harry smirked at her, "well I've got you to thank for a lot of that now don't I, and not just helping me practice," he said with a wink. Luna giggled, it had been over a month since the first task and on top of daily practice, Luna had been getting all three of her holes stuffed by her owner multiple times a day, resulting in Harry's magical power growing as a daily occurrence. "You forgot one thing though master," she teased, "will decapitation kill every creature you might face in the lake?" With that she twirled her own wand and another sharp red arc flew through the air, bisecting the dummy diagonally across its torso leaving the top half to slide to the ground with a dull thud. Harry laughed, equal parts impressed and proud of how far his pet had come. "Good point Luna, I guess I'll just have to make sure there's nothing left, BOMBARDA!" The remaining piece of the dummy suddenly exploded into thousands of tiny pieces while Harry wordlessly conjured a shield in front of the pair. Luna giggled and grabbed him, kissing his neck desperately, not even trying to hide the arousal that had arisen from seeing him effortlessly perform such powerful magic and had resulted in a rapidly growing wet patch on her panties. Normally it wasn't a problem as she rarely bothered to wear clothes when she was in the room of requirement with her owner, but for practical reasons she'd usually be dressed when practicing spells or duelling. "P-please can I touch myself master?" She begged while lathering him with kisses. Harry smiled at her, "I suppose so, as long as you give me a show my little slut." Luna beamed and stepped back, her panties now almost soaked through, it had taken a while to convince Harry to degrade her like this, but every time he called her his whore or his slut, her pussy would gush, both as she loved being reminded of her place, and of exactly who she belonged to.
Stepping back, Luna unclasped her robe and let it fall to the ground, revealing a tight black corset, lacy black underwear and thigh high stockings which contrasted amazingly with her creamy, pale skin. Taking Harry's hand, she led him over to his armchair, making sure to put a noticeable sway in her hips with each step. Sitting back, Harry took in the sight in front of him as Luna slowly began swaying her hips and thrusting her chest towards him, her tits barely contained in the tight leather around them, turning around, she bent over in front of him while backing her ass to just in front of his face, legs spread wide before she pulled her wand from her stocking, casting a weak cutting spell on her panties, causing them to drop from her spread ass cheeks revealing her tight, pink little asshole and her dripping wet pussy. Glancing lustfully over her shoulder, Luna reached behind her, sliding her wand deep into her ass, groaning in pleasure. Harry stared, mesmerised by the sight of his gorgeous little toy utterly degrading herself and moaning like a whore for him. Slowly, she reached between her legs and slid three dainty fingers into her clutching, wet cunt. Not bothering with being delicate, she started to finger fuck herself hard and fast, breathing hard as she did. "Fuck, do you like that master, do you like seeing your dirty little bitch play with herself for your pleasure?" Harry smirked, rock hard himself and slowly stroking his cock. "You know I do my little slut," he teased, slapping her ass playfully. Luna gasped in pleasure, she loved being Harry's toy, every chance she got to please him she jumped at it and would do anything for him with a huge beam plastered across her face. "Can you see how hard your little show is making me you filthy little slut?" Harry asked in a mocking tone mingled with that hint of softness and affections that was always present. The sound of his words, coupled with a glance over her shoulder at his huge dick made Luna shake in pleasure as she began to cum over her hand, collapsing back into her masters lap and feeling his shaft pressing hard against her ass as she recovered her breath.
"Oh dear oh dear," Harry chuckled, menacingly, "did I tell you that you could cum my dear?" Harry asked. Luna gasped, "oh I'm so sorry master, please forgive me, you just had me so wet I couldn't help it, sorry master, I can be such a stupid, slutty little bitch sometimes." Harry gently reached out and stroked her cheek, "there, there, I know it was an accident pet, but that doesn't mean you won't be punished for being such a naughty little girl." Luna giggled excitedly, as much as she hated disappointing Harry, it was always worth it for one of his punishments. All he had to say was 'bed' and she scampered over, clambering onto the sheets on all fours before lowering her upper body and head into the bedding, leaving her ass protruding into the air. She teasingly gave it a little shake as he walked over. "So master, do you feel like the whip or paddle today to teach your cheeky little slut a lesson?" She asked innocently, absolutely adoring whatever item he'd pick. She stared in anticipation as Harry reached over and grabbed the paddle, a leather coated favourite of hers with a hard, wooden interior for extra pain, she was getting more and more turned on just looking at it. "I think 20 spanks per cheek," Harry told her, smirking as I did. Luna smiled at her owner and gave her ass another shake, "please sir, I deserve it." Bringing his arm back, Harry swung the paddle forward resulting in it colliding dead centre of her ass cheek, a loud, satisfying slapping noise filling the room as Luna screamed out in pain and even more pleasure. At first Harry had been reluctant to cause the girl any pain at all, but it hadn't taken long for him to realise how much it turned her on, and the more he hurt her the more she fell in love with. Once she'd even squirted just from him whipping her pussy, which resulted in twice as many whips for cumming without permission. Drawing his arm back, he struck her other cheek hard with the paddle causing her delicious ass to jiggle with the force. "Th-thank you m-m-master," she managed between sobs, her pussy already glistening wet...
The last smack of the paddle echoed around the room and Luna fell forwards, her bright red ass burning in pain as she sobbed into the bed. Leaning down next to her, Harry whispered in her ear, "have you learned your lesson slut?" Luna nodded vigorously, "yes master, thank you so much for taking time to punish your naughty little whore, my pussy is so wet though, please can you use me master, stretch my wet cunt and remind me of my place?" Harry chuckled and climbed on top of her, lining his cock up with her soaked hole before thrusting his hips forward and spearing her on his shaft. "She gave out a loud cry of pleasure as she felt her slit forced open by her masters dick and forced her ass back into his crotch to fill herself as much as possible, ignoring the agonising, stinging pain from her beaten ass. "F-f-fuck yes, pound me, r-ruin me, I'm just your worthless fuckdoll, fucking use me," she screamed as her pussy walls convulsed and squeezed his shaft. Harry was in bliss and started pounding into her hard and fast, a satisfying wet slap emanating from her clutching hole with every thrust, and the feeling of his balls slapping against her clit making her moan and pant in pleasure. After a couple of minutes she turned to him, sweat plastered across her face, "please can I cum Harry, p-please, I'm so close." He grinned and leant forward, grabbing her hair and pulling her head back, "you can cum," he whispered, "as soon as I do." Luna mewled in desperation but nodded, she was so fucking close and desperate to squirt all over her masters huge cock. After another minute, she was wriggling about and moaning in desperation, so close, but Harry felt the telltale tightening in his balls and knew he was close. Wrapping his hand around her neck, he whispered, "cum for me you little slut, I want you to moan and shudder on my dick while I fill you up you worthless cumdump." As he said this, Luna felt his dick swell as his warm, sticky load flowed inter her tight cunt. She screamed in pleasure and let her orgasm overtake her, shaking and groaning has Harry felt a flood of her juices engulf his cock and spray out against his crotch. Pulling out of the exhausted girl, he fell back next to her, chuckling as despite being barely conscious she still managed to shuffle over and curl her body up against his own. After a long time of silence and just hugging each other, Luna spoke up. "As much as I want to stay in your arms forever master, it's now only two weeks until the Yule Ball, and you still haven't asked me," she winked. Harry laughed, "ok then, Luna would you like to go to the ball with me?" She gave a little giggle and answered by sealing her lips around his own and began vying for dominance against his tongue with her own. Eventually she pulled back and giggled while eyeing him with a sultry grin, "Well I don't know if you've heard master, but students can often get carried away with their dates after the ball, and what I'm planning is going to make everything so far look tame..."
