Harry looked at the empty expanse of the Room of Requirements, trying to decide how to configure the room, and with it, trying to design the trick he was going to run on Susan for the day. He was aware that games like that weren't strictly necessary at the point. With the intimacy they had built up, a fireplace and some alcohol would be enough to convince her to drop her panties after a 'heartfelt' discussion. Very effective, but also very boring.
For a moment, he thought about creating a fighting ring, which would allow him to teach Susan the ancient muggle art of wrestling, but ultimately decided against it because it was too forward, too uninspired. After cycling through several more alternatives, he decided to go with a relatively simple route, and created another obstacle course, similar to the previous one with slightly amped-up difficulty.
He had been planning to continue watching the recording of Susan after finishing the setup of the room, to get in the mood, but the delay he had determined the final layout of the room meant that he was barely able to finish his task before his plans were interrupted by a knock.
Still, it was an easy disappointment to shrug with a smile, he decided as he watched Susan entering the room, a cute blush covering her face despite her attempts to look calm. She looked so sexy that it took actual effort to keep himself from licking his lips hungrily.
Susan looked at him, but he stayed silent, a smirk on his lips, waiting for her to speak first. It took a moment for her to find her voice. "We're doing the obstacle course again?" she asked.
"Yes. After all, last time, we weren't able to complete it," Harry answered in return, though he made sure to use his voice in a roguish manner, which worked like a thick burst of wind that found its way to the ambers of a forge, making her flare alight in carnal shyness. It wasn't exactly hard to guess what her mind was back on the ending of their last obstacle course, but he refrained from mentioning his rather accurate doubts.
"I guess," she murmured, and started walking towards the dressing room. But for all her shyness, she didn't neglect to put an excessive sway in her steps, which worked wonders in her voluptuous assets. This time, when she disappeared behind the screen, he suppressed his desire to turn the screen transparent. During the design, he had ordered the room to conjure a few different options in terms of clothing, and he wanted to be surprised when he finally saw Susan's selection.
To pass time, he turned his attention back on the obstacle course, casting the necessary spells, from animation spells to make the object move in their own rhythm, to charms that would make the certain parts extra slippery. And when that finished, he dedicated his mental faculties to the next stage of his plan.
Everything else was ready. All he needed was to convince Susan to a bet.
When Susan stepped out of the protection of the screen a couple of minutes later, Harry didn't bother to suppress his desire to let out an appreciative whistle, nor he was afraid of scaring her off. After all, why should he when Susan had picked the second most revealing set of clothes that were available for her, which showed a deliberate intention on her part. Especially since the first dress was a slightly transparent skintight leotard that was a better fit for a strip club than actual exercising.
The one that Susan picked was not too far behind in terms of sheer sexiness though. She was wearing a pair of yoga pants that were loose enough to not to impede the movement, but thanks to her curves, it looked still sexy. But the real killer was her top. She had chosen an emerald halter top that left a majority of her stomach bare, and most of her back. It even had a hint of cleavage, but more importantly, it hugged her chests in a way that left no mysteries about their exact shape. Her underwear was a bit more substantial, but not enough to remove the impact of the amazing sight it presented.
Harry was happy to note that sharing a bath together had such a positive impact on her previous insistence of stinginess in sowing some skin. Because if there was one student that deserved to pridefully wear an ensemble like that, it was Susan.
Admittedly, she was a shy expression on her face, which contrasted greatly with her mode of dress, and at first, his appreciative whistle just exacerbated it. She froze for a moment, making him wonder whether he pushed her too much, but she took a deep breath and continued her walk.
As she closed in, Harry couldn't help but note that her earlier sway was absent from his walk, but without her robe the cover her assets, the difference didn't mean a reduction in the visual experience.
"So, Sue, are you ready to start," he said, using a diminutive of her name without permission, which, arguably, wasn't too much of liberty compared to some of the other things he had done with her, to her, and over her. He was yet to do anything on top of her, but he hoped that it was an achievement that wasn't too far away.
"Same as the last time, right?" she asked, looking nominally more in control of her emotions despite their increased closeness, small break helping her to gather her wits.
"We can do that, or we can do something more … interesting," Harry answered, not bothering to prevent carnal suggestiveness in his tone.
"Such as?" Susan answered, fearful and excited at the same time.
"A bet would spice things up quite a bit," Harry answered. "Only if you think you can handle, of course," he added, once again following with a charming smile just to make sure there was no space for misunderstandings. It would be a pity if things ruined with an accidental insult when he was this close to the finishing line.
Her blush was rather thick, but after seeing her selection of clothes, he wasn't surprised when he heard her tentative acceptance. "I don't know," she murmured, interested, but afraid to commit. "What's the bet?"
"Does it matter, since you're sure that it's trivial to complete," he answered. He waited a moment, curious to see if she would be courageous enough to interject, but she chose to stay silent. "Maybe we should do something fun. Why don't we lose a piece of clothing every time we fail the course?"
"Harry!" Susan exclaimed, shocked by the suggestion, but her voice was colored with excitement, not anger, so he counted it as a win.
"Come on, Susie, it's just a bit fun to spice things up," Harry answered with a laugh. "It's nothing new after the bath we shared, right? And we can always stop whenever you feel uncomfortable." Technically, they had seen each other naked, but Susan was unaware of her lack of privacy. "And technically, it shouldn't really matter because you're sure that you could complete it easily." She waited in silence, trying to process the sudden turn of events. "Well," Harry murmured a moment later, trying to sound disappointed. "If you don't want to take the dare, maybe we should just start for a boring session."
"No, I can do it," Susan added hurriedly, overwhelmed by the prospect of disappointing her crush. Her blush intensified even further when her brain caught up with the commitment her mouth had made, but she still kept her mouth shut, not willing to reverse her position.
"Great," Harry said, pointing at the small dressing section on the corner. "Then, let's decide on the rules," he said as he stopped for a moment to let his gaze dance over her body, devouring the sight. Wearing revealing but sportive clothes, and with her hair bound in a lush ponytail, she had a sexy explorer vibe going on. Her clothes weren't particularly tight, but Susan's curves showed their worth, stretching them to the limit. "I think it's better if we keep them simple. We have three minutes to complete the course, and falling equals disqualification. Clear?"
"Clear," she answered with a throaty tone, but it didn't take a genius to see that she was having second thoughts.
"Do you want me to go first," Harry offered, as seeing him cut through the course would calm her nerves.
Susan nodded, and he launched himself forward with a rapid dash, a smirk on his lips. He passed the first mud pit rapidly, then the tires, trying to make it seem effortless, hoping that it would make overconfident. Of course, he still needed to fail, giving himself an excuse to get rid of his t-shirt. Seeing him getting half-naked at first should help her get comfortable.
Trying to make it look like his fall was due to hubris, he turned to her and shouted. "See, it's very simple-" he started, only to cut short as he made a show of stumbling on a very obvious obstacle.
"Yes, it's very simple," Susan answered, the accompanying laugh erasing most of her stress. "As long as you keep your eyes straight, of course."
"Laugh it off, miss little Auror," Harry answered with a matching laugh. "It's your turn next. We'll see how you'll do." Susan prepared to answer, but her words died before they could be let out when Harry pulled his shirt off with one smooth motion, revealing his muscular chest for her viewing pleasure.
Distracted by the sudden display, Susan just looked at him, her eyes stuck at his chest, affected by his nakedness. "Come on, Susan," he said with a smirk. "No time to waste."
"Okay," she murmured as she walked towards the starting line, in a manner that might be mistaken for confidence by anyone that missed the soft tremble of her fingers. Harry nodded, gesturing her to start, and after a deep breath, she did so.
The first few obstacles were relatively simple, giving her no challenge as she moved. Excited, she picked up some speed, which made her bountiful breasts jump up and down as she walked, creating a delicious view despite the restricted view. And even better, encouraged by her earlier success, she was too late to react when she stumbled on an underpowered tripping jinx Harry had placed in one of the tires, and fell down in a manner that would be extremely painful if it wasn't for the cushioning charms.
"Too bad," Harry said as he walked towards her, giving her a hand as she tried to untangle herself from the tires. Harry vanished them with a wave of his wand, and presented his hand towards Susan. He noted that her palms were sweatier than her exhaustion would suggest, another mark of her excitement. "Everything is alright, I'm hoping," he murmured.
"Cushioning charms worked perfectly," she answered even as she patted her knees to get rid of the dirt.
"Excellent. Do you need any help with the next step?" he said, taking a small step towards her.
"The next step?" she said, trying to act absentminded, but the hitch in her tone betrayed her stress.
"You know, the bet," he answered with a roguish smile even as he put his hand on her sides, his fingers grabbing the hem of her shirt, gently lifting it an inch just to remove any ambiguity from what he was proposing.
"No need to bother," she answered panickedly as she put her hands on his chest like she wanted to push him away, but her hands just rested there, trembling.
"It's definitely not a bother," he said with a widening smirk. She opened her mouth for another argument, but he cut her short. "I insist," he whispered in a throaty voice that did nothing to hide his arousal. "As your teacher, it's my job to help you." And just to prevent her other arguments from developing, he leaned forward until his lips were just an inch away from hers, ready to press against her lips if she dared to speak.
It was enough to make her freeze in a battle between arousal and confusion, and he started to drag her top off slowly, revealing her amazing body in the process. First, her stomach, attractively smooth despite her legendary curves, followed by her breasts, somehow making themselves apparent despite the conservative sports bra trying to hide them away. He pulled back a bit after that, giving her enough space to raise her arms to get rid of the shirt.
But the moment the shirt was away, he was back in the same position, just an inch away from her face. She got even redder, acutely aware of her state of dress. She made no move to pull back, and a moment later, Harry put his hand on her back, directly on the hooks of her bra, cutting her escape in the process.
"It doesn't look comfortable," he said, putting a finger between her bra and her skin at her hook, leaving no doubt about what he was referring for.
Susan stayed silent until she realized that he had no intention of letting her go before receiving an answer. "It's okay," she murmured.
"Maybe I should remove it as well," he countered. "Just to make you more comfortable, of course." Before she could answer, he pulled back, leaving a shocked Susan behind.
He walked back to the start line, this time dashing through the course in full-speed, showing her that it could be completed in less than a minute. Of course, he discreetly placed a few pranking spells on the way, ensuring that Susan's run would not be as smooth. "How was it," he said, aware of the effect the sight of his naked chest was having on Susan, especially with the thin sheen of sweat, adding a quiet shine on his skin.
"Impressive," she murmured, giving the impression that she hadn't been talking about his latest run.
"Excellent. It's your turn once again," he said. She walked to the start line, her skittishness back for revenge. She started running, and Harry let out a whistle. The reason, her chest, jumping up and down boundlessly, ignoring the support her bra was providing. She wrapped her arms around her chest self-consciously, but it affected her balance adversely, and soon, she stumbled on a simple barrier, before even reaching one of the traps Harry had set.
Once again, Harry walked towards her, but this time, she was faster to stand up. "Do you need any help," Harry asked, and considering she had stood up, it was clear what he was proposing.
"No need," she said as she unbuttoned her pants rapidly, and pulled them down. In her hurry, she also managed to pull her panties down a bit, just enough to give the hint of a well-trimmed red patch before she fixed the issue.
"Whatever you prefer, honey," he said, both amused and tempted by the urgency she was undressing. "Do you mind leaving the course so that I could take my turn." She nodded hurriedly before vacating the area, allowing Harry to make another attempt. He could have easily completed it, but getting rid of his pants was a more attractive idea. So, like the first time, he threw himself on the ground at the first opportunity, and while standing up, vanished his pants with a wave of his wand.
Susan let out a gasp, suggesting that his boxers were failing to successfully maintain their task of covering up his shaft, "Harry!" she exclaimed in a strangled gasp, her eyes fixed on something below waist level.
"Come on, sweetie," Harry said even as he walked towards her. "It's not like it's the first time you have been acquainted with the Potter Junior, right? Or shall I remind you about the last time…"
"No need," Susan said hurriedly as she got away. In her hurry, she reflexively followed the previous path, and stood at the start point once more.
Harry was curious whether it was an intentional choice, or in her distracted state, she had forgotten exactly what she was committing on the process. "Start," he called, and she started running. "And don't forget to be careful, as you know what's next if you fail in this round as well."
His last sentence made her stumble on the even ground by reminding her what was at stake, incidentally also answering his earlier question. She was startled for a moment, but panic wasn't the only emotion on her face, as he could see hints of arousal flickering underneath.
I was glad, but not entirely surprised, when she took a deep breath to calm her nerves before continuing her trek, though this time much more carefully. Realizing that she wouldn't be successful like that, she took her arms to the side, using them for balancing rather than for cover. With the care and attention she was moving, she managed to clear every obstacle, even the hidden traps he had placed. But still, Harry wasn't worried.
"Impressive," Harry said as he clapped gently, walking towards her in the process.
"It was good, wasn't it," she said as her chest rose with pride, stretching her bra's capabilities to keep her breasts contained. Unfortunately, her bra managed to resist.
"It definitely was," he said, fanning the flames of pride she was feeling. He stood in front of her. "But there is still this round's forfeit," he added as he put his hands gently on her waist, like they were about to start slow dancing.
"But… I completed the course," she said.
Harry pointed at the clock that measured the lap times. "Yes, you did. Unfortunately, you did it in four minutes, twenty-two seconds, almost ninety seconds more than the allotted time." He smirked as he brought one of his hands lower, fingers hooking at her panties, while the other reached to the hooks of her bra, all the while she stood frozen, unable to process the shock of the moment.
"So, which one you prefer? The top, or the bottom…"
