Harry was woken up the next morning by the delectable suctions of his slave's mouth on his morning wood.

"Good morning, Pet." Harry said with a content groan. Hermione, who had been solely focused on his cock before, looked up at him but kept bobbing her head on his stiff shaft.

For a few short minutes, Harry just lay back, closed his eyes and enjoyed the sensations of his perfect little slave pleasuring him. He was throbbing in her mouth, leaking copious amounts of pre-cum that was immediately lapped up by her busy tongue.

Soon, he was getting close. He reached out and buried his fingers in Hermione's hair as he pushed her face into his crotch.

"Here it comes!" he yelled. "Look at me!"

Hermione peered up at him, her reluctance clear in her eyes, as Harry groaned and jerked his hips upward. He emptied his balls into her mouth, bursts of cum splattering against the back of her throat. She kept her lips wrapped tightly around his shaft to not spill any of his seed, even when her cheeks were bulging slightly.

With a content sigh, Harry then lowered his hips and slid out of the girl's mouth.

"Amazing as always." he said to her happily. "Are you ready for your morning spanking?"

Hermione, kneeling on the bed in all her naked glory, looked at him pleadingly. But then she gave a resigned nod and turned sideways, arching her back and raising her firm butt. Not a single noise of protest escaped her lips that were still pressed together, sealing the load of cum in her mouth.

Harry was amazed by her behavior. They really had made good progress the day before, he thought to himself. She was behaving exactly like a submissive little whore now, exactly how he wanted her to act.

He rose from the bed and stepped next to her, palming her soft bottom cheeks. There were still some pink marks from the spanking the day before. He would be a bit gentler with her today, he decided. But she would still get her spanking, of course.

"That's a good little slut." he said lowly and raised his hand, bringing it down hard on her butt.

SMACK!

"HHHNNGG!" Hermione groaned, finally making some noises again. But that, too, was how he liked it.

The rest of the Sunday progressed quietly. Like the day before, Harry and Hermione spent their time in the Room of Requirement. They were training shield charms that day, and Hermione once more proved to be a great little helper. To show his appreciation, Harry decided to give his slave a short break and didn't use her any more that morning.

In the afternoon, they continued their spell practice. When Harry felt confident that he could continue without Hermione's help, he told her to go through a number of books on sex magic that the room provided. He ordered her to compile a list of all spells or potions that she could be useful or that she thought he might like. Hermione spent the rest of the afternoon with that, while Harry improved his proficiency with more advanced shield charms. He didn't make use of his slave in any other way, but he promised her that he would remedy that in the evening.

After dinner, they returned to their own chambers.

"Get naked, Pet!" Harry told his slave as soon as the portrait closed behind them.

Hermione quickly shed her clothes and knelt down, looking at him apprehensively, her cheeks slightly blushing in embarrassment.

Harry grinned at that. Even after all they had done, she was apparently still getting embarrassed over having to expose herself to him completely. But he supposed that it wasn't too surprising. She had only been his slave for six days. Natural reactions like this would take a while to fade completely. He actually liked her like this. She looked incredibly cute, he thought.

"Don't worry. You'll have a lot of fun tonight." Harry told her with a grin. "You've been a very good girl today, and I will reward you for that."

The brunette still looked worried, but slightly less so.

Her anxiousness increased, however, when Harry then also shed his robes and outer clothes.

From where she knelt on the ground, Hermione fearfully watched as Harry stripped naked and took a seat on the couch, her eyes focusing especially to his hard cock.

"First, I'd like you to re-do the spell to increase your boob size." Harry said.

Hermione fished her wand from the pile of her clothes and gulped. She hoped that she would manage to perform the spell again, fearing her punishment if she didn't, please her Master. She was much relieved when the spell succeeded after a few tries, increasing her boobs by a bit more than one cup-size once more. The increased weight was unfamiliar, and her skin of her chest ached slightly, but her embarrassment outweighed her physical pain by far.

"You look absolutely stunning like that. Like the perfect little whore that you are!" Harry exclaimed. "Now, come, Pet, crawl to me!"

Hermione nervously approached him, blushing even more from the demeaning act of having to crawl like an animal.

When she reached him, Harry softly strokes Hermione's wavy hair. "Climb on my lap!" he commanded.

Hermione sighed internally, realizing where this was going. She rose up and tried to sit down sideways on Harry's thighs, but he pulled her around so that she was straddling him. His stiff cock was hovering right beside her pussy.

A small reluctant groan escaped Hermione lips as Harry took her enlarged boobs in his hands, starting to massage her flesh and pinching her hardening nipples. The trip of his cock bumping against her entrance, and Hermione realized with shame that she was getting wet.

Harry noted it, too, and grinned at her.

"You can't wait to have my cock in your wet cunt, can you?" he asked with a smirk. "Well, go ahead! Take it in your pussy!"

Hermione blushed profoundly as she reluctantly reached for his firm shaft and aligned it with her entrance. She wondered why she was feeling this humiliated, when she had done much more demeaning things before, but she realized that this was the first time that Harry took her where she was on the top, nominally in control. Only that she wasn't in control, of course. But still, as she lowered herself on his cock, it felt as if she was raping herself this time.

She sank down slowly, his stiff rod sliding further into her moist vagina, until she came to rest on Harry's lap, having fully impaled herself with the cock that was bottoming out in her cunt. His girth was stretching her pussy in ways that were familiar by now, but still slightly uncomfortable. But despite the slight pain, much to her shame, it also felt very good at the same time. She didn't want to like it, but her body betrayed her once again.

Hermione's breath hitched when Harry gyrated his hips, sending pulses of pleasure through her abdomen.

"Oohhhh!" she moaned softly, only to feel mortified with herself moments later.

Harry enjoyed the sight of the shifting expressions on her face while he continued to fondle her tits.

"This is nice, isn't it?" he said with, also groaning when he felt his slave's tight pussy twitching around his cock.

"Now, I want you to keep still and not move your hips."

Hermione blinked and Harry chuckled at her confusion.

"Believe me, this will be as difficult for me as for you." he said. "But what I want you to do now is to tell me of the results of your research this afternoon."

"The-the-what?" Hermione muttered.

"The research on the sex magic." Harry repeated. "What are your results?"

"I-I-It's in my bag." Hermione stuttered.

"No, I just want you to summaries it for now." Harry told her, his hands still on her boobs. He resumed gyrating his hips very slowly, trying to resist the urge of grabbing his slave's hips and fucking her forcefully. "What spells are there, what potions, what can we do?"

"I-I divided it in several parts." Hermione finally answered. "There-there are spells to make-make a woman orgasm, though in supposedly won't feel as good as a - aaaahhh! - a reaaal one. There is a spell to lactate. Spells to stretch out or to increase tightness of-of both vagina and arse. To-to increase boob size, of course, the spell I used just now. But like the other modifications it only lasts few hours."

"Yes, but that's alright for now." Harry said, slowly rolling his hips, sliding his cock back and forth inside her clenching pussy by mere inches. "Please continue."

"There - aaahh! - there are cleaning charms for pretty much everything. Especially as-as preparation for anal. Ooohh!"

"Do we need those? Don't you like to clean my cock with your mouth afterwards?" Harry asked with a smirk.

"I-" Hermione groaned. She knew what answer was expected of her. A good little slut wasn't supposed to dislike the flavors that came with being used. "I - yes, I love it!" she assured him.

"Good. What else did you find?" Harry asked while he continued his movements.

"There are - oooh god! - similar spells for men like for women." Hermione continued between heavy breaths. "For example, to increase the size of the –- oohhh – the penis. Not that you need it, Master!" she added quickly.

Harry knew that he was slightly above average, but he reckoned a larger size might not hurt occasionally. Well, it wouldn't hurt him, that was.

He nodded. "Might still be good to keep it in mind for when I want to stretch your tight holes a bit further."

Hermione whimpered.

"Continue." Harry said, increasing his movements of his hips and rubbing his thumbs over her hardened nipples.

"Ooohh!" Hermione moaned. "Ahh! For-for men, there are other spells. To increase stamina. Or-or sperm production. But I think your magic is helping you out there already. I read that-that it can happen to-to wizards who are sexually active during puberty. And the spells don't last long and are apparently uncomfortable. But - ooohh god! - potions are better."

Harry nodded, pacing up his movements even more.

"Oughhh! Ohhh goood!" Hermione groaned. "Potions usually are better. For-For the women too. It lasts much loooo-longer. Or the effects can even be permanent."

"Can we brew them?"

"Ahhh! I don't know! But-but there might be a shop in Hogsmeade that sells them."

"Oh?"

"Yes - yeees! - yes, in a side alley. I wasn't inside, but I saw a small shop for-well, a magical sex shop there last year."

"Great." Harry said. "We'll go there next weekend. Is that all?"

"Ye-Yes, those are the results." Hermione panted.

"Great!" Harry exclaimed and moved his hands on her bottom, pushing her closer against him.

"You may start moving now!" he said, and Hermione began to eagerly meet his thrusts with her own hips.

After all the teasing before, she was getting desperate with need. She moaned and whimpered as his stiff cock rapidly pounded into her slick love channel, sending waves of pleasure through her body.

Harry felt that he wouldn't last much longer, and he knew that Hermione was nearing her climax, too.

"Please, may I cum?" the brunette whimpered. She was riding his cock to her fullest now, her perky tits bouncing up and down with her movements. It was a mesmerising sight, and it gave Harry another idea.

Harry shot the begging girl a predatory grin.

"Hmm. Nope."

With that, he lifted the surprised girl off his cock and threw her sideways onto the couch on her back. He straddled her torso and put his cock between her enlarged boobs.

"Squeeze your tits together for me!" he demanded. "This is where I want to finish!"

Hermione looked up at him with betrayal in her eyes at being denied her orgasm, but she did as commanded and pressed her boobs around his slick cock.

Harry rocketed his hips back and forth, enjoying the pressure of the soft flesh around his throbbing member. It didn't take much longer until he was hit with an incredible climax.

"Ahhh! That's it!" he groaned in orgasmic bliss. He spurted his seed all over her face, coating her adorable features with his spunk. Lines of semen landed on her cheeks, chin, and across her lips, and drops also on landed on her neck and collarbone.

"You're such a good little whore!" Harry praised her when he came down from his orgasmic height.

Hermione looked back at him, humiliated, but also slightly disappointed.

"Why so sad?" Harry asked, even though he knew the answer. He knew that she was horny and needed release.

Hermione's blush intensified, but she didn't reply. She was afraid of speaking up.

"Oh, I guess you wanted to cum, too?" Harry asked.

After a short hesitation, Hermione gave a tiny nod in response, embarrassed beyond belief.

"Well, I did promise you a reward, didn't I?" Harry said.

Hermione frowned slightly at that.

"Oh, you think this-" He pointed at her cum-covered face. "was your reward?"

He chuckled at her confusion. "Don't worry. Your reward is what comes next. It's not even eight o'clock yet. We have still a few hours left this evening."

Hermione looked as if she couldn't decide if she should be relieved or fearful about that.

"Well." Harry said and stood up from the couch. "You want to cum, right?"

Another small nod from the embarrassed girl.

"Crawl to me, then." Harry said and took a few steps away from the couch, halting in the middle of the room. Unsteadily, Hermione slid off the couch and crawled to him.

"Kneel!" Harry said and the Hermione got into her Present Position, becoming increasingly nervous again.

Harry walked to a cupboard on the side of the room and took a vase from it, inspecting it for a moment before transfiguring the vase into a large bowl. He then stepped back to his slave.

"Knees apart!" he told the girl, who shifted on the hard wooden floor, increasing the spread of her legs and exposing her glistening sex even further.

Harry bent down and laid the wide bowl on the ground between her knees.

Hermione watched his actions with apprehension, unsure what was going on.

"Do you have a good view on the grandfather clock at the side of the room?" Harry asked next, pointing to the clock slightly to their side.

Hermione tilted her head and nodded, even more confused now.

"Alright. So, we can start." Harry said with a widening grin. "Put a finger inside your pussy!"

Hermione's blush that had never quite receded became more pronounced again when she did as commanded and put the tip of her right index finger inside her moist pussy. But her confusion was still the most prominent emotion in her expression.

"Now, you want to cum. So, as your reward, you will get to cum." Harry told her with a smile. "Often. When I'm done explaining the rules, you will start masturbating. You don't have to masturbate non-stop. But you should get yourself off at least once every quarter hour this evening."

Hermione's eyes widened as Harry explained the rules to the fun little game, he had thought out for her.

"You have my permission to cum more often if you want, that's up to you. But if you don't manage to bring yourself to orgasm at least once within each quarter hour, you will inform me of that. That's an order, so you can't escape this by faking an orgasm or so. If you fail, I'll give you a worse pussy spanking than you could possibly imagine. Understood?"

"Master-" Hermione began to plead.

"Understood?" Harry repeated.

Hermione nodded resignedly. "Yes, I understand."

"Good." Harry said. "As I said, you can pause masturbating in between if you find the time. But you will keep at least one finger inside your pussy this entire evening. And you will stay in position. Any questions?"

Hermione hesitantly shook her head. It was easy enough. Stay in position, masturbate, and climax at least once every fifteen minutes. It was just so humiliating! And to think that this was a reward! Her Master was truly a sick bastard!

Harry looked at watch, it was almost exactly a quarter to eight.

"No? Great! Then start!" Harry said, and Hermione gave a small groan in recognition.

Hermione was embarrassed beyond belief, but she knew that she had no choice if she wanted to avoid a much worse punishment. Besides, she had been teased so much before that she had an overwhelming need to finally bring herself to release. She just didn't want to do it in front of Harry. She didn't want to let him think that she actually enjoyed the things he was forcing her to do. But it was of no use.

Hesitantly, the brunette began massaging her boobs with her left hand. She closed her eyes, trying not to focus on where she was. She began rubbing her thumb in circles around her clit while pushing her index finger further into her pussy, her middle finger joining in soon afterwards. She slightly tilted the fingers forward until she found exactly the right spot and increased the pressure.

"Oooohh!" Hermione couldn't hold back the moan at the spike of pleasure, and she felt how her already slick pussy got even wetter. Her fluids began running down her fingers and dripping down from her hand into the bowl.

She increased the pace of her movements, and when she pinched her left nipple with her other hand a few minutes later, the sensations sent her over the edge and her orgasm hit her.

She squeaked quietly as juices squirted out of her dripping slit, splashing into the bowl between her knees.

A clap of hands brought her back to reality. Hermione blinked as she opened her eyes and saw Harry sitting on the couch, applauding her, a wide smirk on his lips.

"That was amazing!" he praised her. "A great show! You look very cute when you orgasm, you know that?"

Hermione only whimpered in response and looked down in shame, flushed scarlet. If she could have blushed any harder, she would have. Once more, she had lost all her dignity and acted like a complete slut. And she knew that she would have to repeat this involuntary show many times this evening.

Harry returned his attention to the book on Quidditch he had been reading, while Hermione had a few minutes to contemplate her misery. She was left kneeling naked in the middle of the room, a finger in her moist slit, her fingers wet with her juices, and Harry's cum was slowly drying on her face, filling her nose with its scent. But the minutes passed, and soon she had to start pleasuring herself again.

It was actually getting easier as the evening progressed. Her pussy became more sensitive the more she stimulated it, making it easier for her to bring herself to her climax.

After she had succeeded in getting herself off for the third time, squirting in the slowly filling bowl with a loud shriek, Hermione suddenly realised what the bowl was for. The juices collected there weren't only evidence of her enjoyment, meant to humiliate her further. She had the strong suspicion that she would have to drink the contents of the bowl before the evening was over. She groaned, but she knew that there was nothing that she could do to prevent this next degrading act.

Things got worse for her after that. When she was busy fucking herself on her fingers fifteen minutes later, Harry walked up to her and rubbed his stiff cock.

"You have no idea how hot you are!" he breathed as he began jerking off into her face. Hermione could only close her eyes and try to ignore the fapping sounds before her while she continued pleasuring herself.

A few minutes later, Hermione climaxed again. The sight of the girl's o-face and her noises as her orgasm hit her tipped Harry over the edge, too. As she was moaning in orgasmic bliss, Hermione had opened her mouth slightly, allowing two spurts of cum to land on her tongue, giving her a first taste of her next meal, though she didn't know that yet. Harry mostly aimed his spurting cock at her face, careful to give all her features equal attention as he coated her adorable face with his seed.

"You're even prettier now!" he said happily when he was done and wiped cock clean in her hair.

Hermione only whimpered in response to the latest degradation.

The scene repeated itself five more times as the evening continued. After a while, Hermione no longer fully stopped with the sensual movements of her fingers even when she could have paused for a few minutes.

She couldn't bear to kneel idly in the room, naked, a finger in her dripping cunt, while her Master's semen slowly trickled from her face. So, she slowed down her pace when she could, but always kept two fingers slowly gyrating inside her to keep the pleasure coming. It stopped her from having to focus too much on the reality of her situation.

Though focusing on her surroundings soon became more and more difficult for her, anyway. After one and a half hours of her "reward", she began to get truly uncomfortable. Her abdomen was aching after one orgasm after another had coiled through her lower belly. Her knees hurt badly and she shifted around on the hard wooden flow, trying in vain to get more comfortable. And her face was glazed with white gooey semen that was slowly drying on her skin. It dribbled down her chin and onto her breasts, which felt more and more sticky. A trickle of it trailed down from between her breasts, down her belly until it ended between her spread legs. She could feel that she was rubbing some of her Master's seed into her vagina when she fucked herself with her fingers.

But despite all of that, the only thing she could think about were the sensations coming from her overstimulated clit and pussy and her absolute need to bring herself to her next orgasm. She couldn't even bring herself to pause anymore. Her body was on fire as she gave in to the sensations. Her skin was glistening with sweat, and her mind was becoming fuzzy.

When the clock struck ten, Hermione was currently busy rubbing her clit with one hand, while fucking her aching pussy with three fingers at once. Finally, with a shuddered breath, she came all over her hand, filling the bowl between her knees with some last squirts of pussy juices.

"Alright, that's enough, I think." Harry called out, and Hermione blinked several times as she opened her eyes, staring at him with unseeing eyes.

Breathing heavily, the brunette slowly withdrew her drenched fingers from her still quivering pussy. Her fingers were wrinkled from the wetness. It took her a while until she had gathered her breath.

Harry watched her with a smirk until he felt that she was responsive again.

"Well, wasn't that fun?" he asked cheerfully.

Hermione only looked back at him; her exhaustion clear in her eyes.

She felt ready to lie down and fall asleep on the ground right then and there, but she suspected that her Master was not done with her yet.

"You look tired." Harry said, and Hermione gave him a small nod, looking up at him hopefully.

"Well, don't worry. We can call it a night soon." Harry said and smirked. "But first, I think you should clean up the mess on your face and your body."

Hermione scowled slightly, giving a despondent sigh. She knew what she had to do, and she had kind of expected it. Reluctantly, she began to wipe the sperm off her face with her fingers, licking them clean, filling her mouth and gulping down one load of sperm after another. The taste was unpleasant as always, but she was slowly getting used to it by now. Only the sheer amount of semen that she was forced to swallow caused her to gag on it repeatedly.

When she was done with the demeaning task, she anxiously looked up at Harry's smirking face from where she knelt

"Did you enjoy your meal?"" Harry asked. "Or would you like a drink to wash it down?"

Hermione glanced down on the filled bowl below her and groaned.

"Yes, that's what I'm talking about." Harry confirmed. "Do you want to drink it?"

"Does it matter?" she asked dejectedly. "I suppose I will drink it either way."

Harry chuckled. "You got that right. Do I have to order you, or will you do it voluntarily?"

Reluctantly, Hermione reached for the bowl and took it in her hands. She knew there was nothing to be gained by defying him, and she didn't want to risk another punishment.

She raised the bowl to her face, eyeing the contents critically and taking a careful sniff. The bowl contained a mixture of her watery cum and the thicker syrup of her pussy, and probably some drops of sperm, too. It smelled pretty much like the scent that filled the entire room, only more pronounced. It wasn't terrible, at least.

She lifted the bowl to her lips and took a small sip of the watery, mostly clear liquid. The taste was tolerable, she found. It was slightly sweet, but there wasn't a strong flavour. She could taste the small amount of sperm that had dripped in there, and she caught a slight whiff off some droplets of pee, but it wasn't enough to cause her to gag.

As she slowly emptied the bowl with small sips, Hermione thought that the act itself was degrading, but the taste was much better than that of semen, never mind her own arse.

"All done, Master." she said with a small voice when the bowl was empty, putting it back on the ground.

"Well done, Pet!" Harry praised her. "You're such a dirty little slut. I bet you loved that! Did you enjoy your reward?"

Hermione looked up at him despondently. She was aching all over, and her belly was filled with cum and pussy juice, which she could still taste and smell in her breath. But she knew that a good little slut had to be grateful for any pleasure she was granted, and she had orgasmed fifteen times this evening.

"Yes, Master. Thank you, Master." Hermione finally whispered.

"Well, I'm happy that you had fun!" he said cheerfully. "If you continue to be a good girl, you might get to do this again someday."

This time she didn't reply and stayed silent, only looking up at him with wide eyes.

"Now come, let's get you cleaned up!" Harry said and pulled Hermione up to her feet.

Dizzy and unsteady on her feet, the brunette followed Harry into the bathroom and joined him under the shower.

Her exhaustion was catching up with her and Hermione felt ready to pass out while the hot water rinsed her skin. She almost welcomed her Master's firm movements as he soaped her up and cleaned her body and sticky face. He also let her rinse her mouth with water and wash out her mouth thoroughly. He then proceeded to hold her close and massage her while they stood under the stream hot water, and she almost fell asleep in his arms.

When they exited the shower, Harry gently dried up the drowsy girl with a soft towel. Hermione finally felt nice and clean again, and at the same time more tired than she had ever been before. Her knees almost gave way in that moment, but Harry caught her and carried her to bed.

She felt herself drift into sleep while Harry laid her onto the soft bed and climbed into bed after her, throwing the blanket over the both of them.

When Harry snuggled up behind her and closed his eyes, Hermione was already fast asleep.
