Chapter 28: Lessons for Susan

For a couple of days after the encounter with Daphne, Harry stayed hidden in the Room of Requirements, choosing to focus on his magical studies and combat training. Even for him, exhausting two embodiment of sexiness back to back had been rather fulfilling. Hermione had been surprisingly willing after tapping into her arousal, and Daphne's stamina was boosted through magical assistance, stretching the encounter from the early afternoon to the edge of the midnight, fulfilling his need for carnal experiences.

But not to a point where he would reject a convenient opportunity, of course, he thought as the door opened, and a familiar redheaded figure stepped inside, even her conservative robe failing to completely hide her delicious curves. He didn't know what she was trying to do, but in his sated state, he was willing to wait passively to see rather than to push aggressively.

He acted unaware of her presence, keeping his focus on the several magical targets in front of him, animated by the room, moving irregularly to give him a better approximation of a battlefield. Before Susan's arrival, he was practicing piercing spells, cheap and practical but visually dull; but his guest deserved a more impressive show. He took a deep breath, his eyes closed for concentration as he gathered his magic, enough to blanket the room with an oppressive feeling of power. Then, he unleashed a torrent of fire, one thick enough to be mistaken for dark magic.

From the gasp that left Susan's mouth, he guessed that she made that particular mistake for a moment. Harry used the opportunity to 'notice' her arrival. After casting an equally flashy water spell to douse the smoking cinders, all that left from the destroyed targets. "Susan, you're here early?" he asked.

She was still for a second, busy with taking a deep breath to suppress her shock. "Not by much, if you're already here working," she answered as she walked towards the middle of the room, trying to play it casual, but unable to pull her eyes on the smoldering husks. "How long you have been in here, working in this intensity? You seem a bit exhausted."

She was right, as he was rather sweaty and exhausted. "I don't know. A few hours, maybe. I skipped the history of magic, and I had a free period after it," he said with a shrug.

"A few hours! And you still have the energy to throw around that kind of spells?" she asked, too shocked to hide her impressed state, her initial attempt to play it casually forgotten.

Harry shrugged, a suggestive smirk on his lips. "As you can attest, my stamina is nothing to scoff at."

Susan murmured something incomprehensible, the reminder enough to make her turn towards the wall, like she had been captivated by the most interesting pattern she had the pleasure of seeing. A rather blatant attempt to hide her sudden blush, but Harry let her to think that it was successful. Her shyness was cute, especially when compared with her adventurous state once things started going.

"So, were you hoping to find me here, or you wanted to do some training on your own?" Harry asked.

"Training," she answered, again shyly, enough to indicate that the former was the case.

"In that case, I can leave the room to you," he answered, seeing her bluff.

"No! No!" she answered rapidly. Harry shook his head, amused by the imaginary poker skills she had shown. Though, if that was the case, it might not be entirely uninteresting to set up a poker game, especially one of strip variety. "Maybe we can do some more practice."

"Works for me," he answered. "How about some dueling practice?" She nodded shyly, but he detected a hint of disappointment. Unnecessary, as he had quite interesting things in mind. After the months he spent on the room, it took just a moment to change the room into a dueling ring. "Ready?" he asked.

Her eyes slid to the empty space that usually held the screen for her to change. "We're going to stay in your normal clothes, to make sure you can fight in an ambush." She nodded, not feeling confident enough to argue against. "Nothing dangerous of course, ticking spells, paint, and disarming spells."

Susan nodded and took her place at the other end of the dueling ring, but while he was walking on the other side, she sent a disarming spell to his side, trying to ambush him. He threw a warning glare at her. "It's a practice for the real-life combat, so no warning," she said, trying to sound confident, but fragility was not far away from the surface.

He waited until she started to squirm uncomfortably, then smirked. "Good work. It's nice to see you're absorbing my teachings," he added, but just as he said so, he sent a spell of his own, which, unlike hers, managed to connect with the target.

She jumped back, desperately clamping to her wand to keep it in, which was a useless gesture, considering it wasn't a disarming spell he used. She realized that in a moment, and started checking her body to see its impact, only to realize nothing visible had changed. "Did your spell fizzle," she asked with a giggle.

"Must have been," he answered with a shrug, despite knowing that his spell had worked exactly as intended. "Maybe I'm more exhausted than I first thought." She sent a disarming spell towards him, which he dodged rather easily. "Not that exhausted," he added with a widening smirk, summoning a shield with a flick of his wrist. After a brief pause, Susan took the invitation to take the offense, petering him with a variety of spells.

He stuck mostly to shielding and dodging, only using occasional counter-attacks, just enough to prevent her from falling to a lull, but letting them fall wide; a pattern he kept even as Susan got more and more aggressive. He had a plan, after all.

The first sign of his plan working was the sense of discomfort that slowly spread to her face, annoyed by the way her clothes chafed her body; affected by the first spell that landed on her body, adding a small vibration to her body, soft enough to be camouflaged by her movements. She tried to ignore the sensation, but waiting for the opportunity, Harry turned up the intensity of his assault a bit, just enough to force her to dodge more. Only then, he increased the intensity of the vibrations, trying to turn the irritation she felt into something more useful.

It didn't take long for her expression to turn into shock. Harry used the opportunity to take a sneak-peek into her mind, just enough to detect the build-up of pleasure, converted from her earlier irritation. After that momentary distraction, he focused back on his assault, forcing Susan to move around the dueling ring, increasing her arousal further and further.

"It's because of the first spell, isn't it?" she murmured, but the anger that might have accompanied it before had been absent, replaced by a taste of anticipation she had tried her best to hide.

"I don't know," he answered, but his smile telling a completely different story. "Hadn't that spell fizzled due to my exhaustion."

She froze for a moment while trying to decide what to do, barely dodging his disarmer in the process. "Two can play the game," she murmured confidently. It was rather exaggerated confidence, wielded by her like a flashbang to hide her underlying lack of confidence, not that it was important when she turned her wand to herself and murmured a spell, only for her robe, along with most of her other clothes, disappear, revealing her underwear. "The spell won't work without the friction from my clothes, will it?" she said, managing to push a smirk forward even if its edges were trembling as her instinctual shyness tried to establish itself once more.

"Smart choice," Harry said as he lowered his wand, surprised by her rather aggressive choice, but not anyway unhappy about it. And to make things better, she had other surprises, her selection of underwear was in particular. Gone was the cotton granny panties and unflattering bras as large as possible to contain her impressive bosom. They were still a pure, shining white, but it was the end of their similarity. The lacy, skimpy set wrapped her body tight, small enough that most of her breasts spilled freely, enough to make his pants uncomfortably tight. Her panties were similarly deficient, leaving most of her bottom free for his gaze, especially when she took rather excessive turns to avoid his spells.

Distracted by the amazing view she provided, he was almost too late to notice the stunner coming to his way, saved by his supernatural reflexes. "Not bad," he murmured even as he took a step forward, his wand quickening without a warning, raining a number of disarmers on Susan; not intense enough to defeat her, but intense enough to put her into the full defensive.

Free from defensive concerns, he started walking towards her, his spells getting quicker and quicker. She dashed back, hoping to use the distance to put a better defense, but she was only able to take a few steps before the wall behind her prevented her plans on that direction.

Harry decided that it was time for another lesson on battlefield awareness. Two more spells left his wands, both missing Susan with a wide margin, splashing against the wall instead, and he stopped casting. Susan opened her mouth, but her quip about his poor aim never left her mouth when she was distracted by a set of silk-covered chains, freshly transfigured, wrapping around her limbs, leaving her immobile and helplessly-sexy.

She didn't say until Harry was close enough to feel her breath -out of control with a delicious mixture of exertion and arousal. "You win-" she started to say, only to be silenced when she found his lips above hers. No protest, muffled or otherwise, left her mouth as his tongue invaded it, accepting his presence obediently.

Harry couldn't help but smirk at her ready acceptance. Her eventual capitulation was to be expected, but he had been expecting her to play the part of reluctant victim for quite a bit before the naughty minx he had discovered in their previous training session had shown herself. But she turned out to be like the legendary box of Pandora, once opened, no way to be closed down - not that he was complaining in any shape or form.

With that in mind, he didn't think much before grabbing her bra, pulling it up to free her mounds from their rather deficient prison. One hand, he left there, mercilessly digging into her soft flesh, enjoying her moans, while the other found her panties, their flimsy fabric barely resisting as he pulled it off in one sharp move, leaving her entrance free. After a moment's break where he pulled his pants down, he pushed forward, passing through her nether lips, sopping wet with arousal.

A moan escaped her mouth, loud enough to make him happy about the default silencing charms on the room, not bringing any passerby to the room. And since it was not a problem, he decided to cut loose with his treatment. His lips slid until they started resting on the smooth skin of her neck, before putting one sharp bite on her skin, adding to her

"It hurts," she moaned in a way that managed to achieve the impossible, making him even harder.

"Do you want me to stop," he asked after letting his lips separate from her skin for a moment.

"No!" she moaned in urgency, not that it surprised him very much. He hadn't needed his mind-reading powers to predict the answer, and his lips had moved down while waiting for the answer. Soon, his lips reached the beautiful expanse of her breasts, subjecting the sensitive skin around her nipples to the same treatment, earning an even louder moan of pleasure in response, accompanied by her nether lips clamping around his shaft even tighter.

Focused on enjoying the moment, he hadn't been expecting the door to open, nor he was expecting a certain bushy-haired friend of his to enter. He was sure that without the Occumency, he would have frozen stiff in shock, but additional thinking speed definitely came useful.

The first thing to ensure was to isolate Susan from the situation as much as possible. Luckily, his wand was still its holster, so all it took was a flick of the wrist to get it back. A couple of spells later, an eye fold was tightly wrapped around Susan's eyes, and a modified silencing spell that prevented her from hearing his or Hermione's speech.

His wand disappeared in his holster once more while he turned towards Hermione, whose expression marred in shock and disappointment as she glanced at the scene. Harry noted that her robe was parted, revealing a crimson teddy underneath. She clearly came prepared, likely wanting to surprise him with an enjoyable treat, only to find him gorging himself with a different pleasure.

The easiest thing to do would be to obliviate her, sending her back with the memory of not finding him. But where was the fun in that, he decided, his instincts begging for something more enjoyable, one that he wanted to achieve without cheating through magic?

"Hello, Mione," he said with a cheerful wave, a rather absurd move, further enhanced by the fact that he was still drilling Susan to the best of his ability, his cheerful greeting mixed with her moans.

"Ha-Harry!" she exclaimed in shock. "What are you doing?!"

"Stress relief," he said casually. She murmured incomprehensively, forcing him to peek into her mind to actually understand what she was trying to say. "Well, yes," he added. "I didn't think it's fair to bother you every time I felt stressed. It's not fair to distract you from your OWL's to such a degree. But since you're here, do you want to join. I'm sure it'll be really enjoyable with a little assistance from Susan."

The expression of shock and incredulousness on her face was too delicious to resist, increasing his pleasure even further. He waited until she managed to gather a sliver of control, opening her mouth to answer, but before she could, he ordered the room to loosen the shackles around Susan's arms. Surprised by the sudden lack of support, she fell forward, and Harry pushed her shoulder at the last moment to put her on her knees instead. Her mouth, open in shock, gave him the perfect to push his shaft, still slick with her own juices, deep into her throat.

"But… I thought," she murmured, her eyes still stuck on the view.

"Come on, Mione, you know the year I had. I need a lot of stress relief, and most of the time, you were studying."

She continued to watch the view, transfixed, for a while, while Harry used the opportunity to ravage Susan's throat, but he kept his eyes on Hermione's, failing to resist the temptation to cheat a bit. He increased the pleasure she was getting from watching him dominate the others, so much that a distinct wetness appeared between her legs, the thin fabric of the teddy she was wearing a poor choice to keep it hidden. Her nipples, barely visible on the edge of her half-open robe, started to get harder and harder.

Harry chose to speak when her arms started to twitch. "Have you decided?" he asked glibly even as he reached his limits, and started to fill Susan's throat with his seed, leaving her in a coughing fit.

"I need to go," Hermione exclaimed, her reason finally managing to rise high enough to defeat her shock, which was unfairly assisted by her arousal.

"Sure, I'll see you tonight, in your room," Harry answered, even as he ordered the room to create a desk behind Susan before pushing her on it. He canceled the silencing spell only when the door slammed behind Hermione, leaving Susan panting on the desk, her plump bottom pointing upwards. And since his wand was still in his hand, it took only a moment to cast a spell that would clean and lubricate her tight hole.

"Harry, what are you doing-GGG!" Susan started, only for it to melt into a panicked yelp.

"Taking the reward of my victory," he answered glibly even as he pushed his shaft forward, forcing himself into the untouched tightness of her puckered hole. She cried in pain, but he ignored, aware that it wouldn't take long for Susan to start enjoying the pain. She opened her mouth to argue, only to be silenced by a sharp spank to her bottom. "No backtalk against the victor," he warned even as her ass wobbled under his slap.

"Okay," she murmured obediently, and tried to stay silent, but it was interrupted by her rather frequent cries as he tested the elasticity with a series of escalating challenges. Soon, the sound of flesh hitting flesh filled the room, accompanied by her cries, the ratio of pleasure increasing with each repeat.

Soon, he leaned forward, and wrapped his hand around her beautiful auburn hair before pulling her up in a painful manner, while maintaining the pace of his assault. "This is the punishment for underestimating your opponent. Maybe the lingering pain will be enough to remind you to look for hidden traps," he reminded.

"I promise I will," she cried, broken under a delicious mixture of pleasure and pain.

"You will refer me as the professor while we're studying," he reminded her in a sudden struck of fancy. "Or we will visit the implications of your lack of respect next."

"I'm sorry, professor," she moaned. "It'll never happen again…"

"See that it doesn't," he said casually before using another sharp spank as the punctuation.

There were certain advantages to the position of a private trainer, he decided…
