Chapter 1

I can't believe that idiot!" Hermione growled in anger as she looked outside, the spot her boyfriend disappeared with the distinctive crack of the apparation several hours ago after a pointless argument. "How dare he can leave for such a silly reason, in the middle of such a mission."

Harry, unfortunately, very well could, as it wasn't the first time he had experienced that particular betrayal. Though, that didn't mean that he wasn't disappointed greatly, with the importance of their mission.

"We can't do anything but wait a bit more, and continue if he doesn't arrive," Harry said.

Hermione let out a growl of annoyance, turned rapidly, and disappeared into the magical tent, too angry to take note of the way her skirt lifted.

Harry didn't miss that fact. He had been noticing the way the growth spurt hit her for the last year, though he had been doing his best to ignore that fact, knowing that Ron had feelings for her.

A concern that was weakening significantly the longer Ron chose to stay away.

"His loss," he said with a sudden smirk. Not really characteristic of him, but after spending weeks and months trying to take down a near-immortal evil wizard, his nerves were frayed.

He deserved some fun.

He waited a moment, familiar with Hermione's behavior enough to know that her reaction to that anger would be to prepare for a shower. Not only that, he knew exactly when to walk in, not to see her in an exposed position, but merely suggestive.

He walked in just as she had thrown her coat, revealing her blouse — one that Harry remembered to be a boringly modest piece just the last year, before her breasts decided to grow a couple sizes in one summer.

Pity, she was still wearing her bra underneath, preventing what would have been an amazing show.

"You should be careful walking around like that. We don't want to deal with his jealousy if he returns," Harry said, doing his best to sound concerned.

The growl of anger she let out was beautiful. "And why should I care what he feels, after he abandoned us," Hermione shouted in indignation. "It's him that decided to get jealous for the stupidest of reasons. I fail to see why I have to tiptoe around it."

"Well—" Harry said, only to be silenced by Hermione's angry shout. He raised his hands in surrender as she looked at him, before she stomped toward the bathroom, not looking at him again.

Not even when she suddenly stopped at the entrance, and removed her blouse to give him a momentary glimpse of her naked back before she stepped inside, the door slammed behind her.

Which was good, because it meant that she had missed his smirk.

"Always with the overreaction," Harry chuckled as he walked into his room — glad for all the facilities of a magical tent. After all, her tendency to overreact was very clear. She was the one who decided constantly time-traveling was a good method of attending extra classes, or decided to instigate rebellion of house elves. Not to mention, she had surprisingly loose morals once ticked — the fates of Rita and Umbridge being the most excellent examples.

Not to mention, those solutions were hardly as perfect as she thought them to be — as evidenced by her decision to erase the memories of her parents, not that Harry was stupid enough to mention that to her...

Comparatively, Ron's sudden disappearance triggered her anger perfectly, and Harry knew exactly how to stroke it further.

He wanted her peeved and irked, curious just how far her excessive decision-making would be pushed.

As he went to his room, he left the door deliberately cracked as he get rid of his shirt, and lay on the bed, in a position where he would see her once she left the shower.

It would be a good test to just how far her anger would develop in the shower.

An hour later, Harry was still laying down in his bed, still faking sleep, waiting for Hermione to finish. Though he had to recast the spell to make himself see without his glasses. Pity that spell barely lasted half an hour, making glasses still a necessity.

However, despite the long disappearance, Harry didn't have the slightest worry about his plan.

The reason was simple.

Other people might calm down once left alone, but Hermione didn't work like that. She was a woman of action, and the longer she stayed with her thoughts, unable to resolve them, the more exaggerated her ultimate response would be.

Especially since she was locked in a room with no book to distract her from her thoughts.

The distinctive click of the door distracted him from his thoughts, and he closed his eyes immediately, only keeping them slightly cracked to get a glimpse of the show.

It took all of his power not to celebrate his success when he saw Hermione stepping out of her usual bathrobe. But luckily, the bathrobe was convenient clothing, the tightness of a belt only thing between a prudish display and an erotic photoshoot.

Hermione decided to split the difference between those two concepts. The belt was still in place, but decidedly loose, while the top was loose enough to create an excellent window of her cleavage. Not particularly wide, but deep enough to reach to the middle of her belly.

True to her personality, she started shuffling, a little antsy the moment her little plan to make her boyfriend hit a snag, of his apparent sleeping.

Harry continued feigning sleep, curious whether she would accept the temporary defeat and come up with a different solution, or double down.

"Harry, are you sleeping," she asked as she started walking to his room, confirming her decision. Holding back his smirk took everything he had, though not soon after, he realized that it wasn't the biggest problem he had.

Hermione decided to loosen her belt a bit more as she walked. Harry wondered if she was aware of just how much of an impact it had on her cleavage as her loose bathrobe moved, or if she just missed that fact in her frustration.

He didn't know which was more entertaining, but in either case, it made it very challenging to keep his erection under control.

"Harry?" Hermione repeated a few more times, getting antsier as he didn't respond.

"Is something wrong," Harry finally murmured, acting like just awakened.

"N-no," she said, her hesitancy clear. It seemed that she wasn't completely sold on the idea.

Luckily, Harry knew exactly how to solve that. "Is Ron back?" he said as he made a show of trying to find his glasses, only to fail.

Yet, the mention of her absent boyfriend was enough to destroy her hesitancy a moment later, and her gaze noticed his search — and his glasses, 'accidentally' left on the table next to the entrance rather than next to his bed.

Telling her that, with his famously bad eyesight, he was not able to see her carefully-arranged cleavage.

It clearly worked, because Hermione didn't show the slightest concern as she sat at the distant end of his bed, half turned toward him, uncaring of the glimpse of nipple he had received.

He let the silence dominate the room, leaving the task of filling it to her.

"What are we going to do now?" she asked.

Harry shrugged, his eyes still half-closed. "We're going to wait until the evening, and if he doesn't return until then, leave," he said. There, he could have mentioned the importance of the mission, but it would have just made her focus on the serious parts. "It's his choice."

"Yes," she murmured as she grabbed the edge of her robe, and for a moment, Harry feared that his little trick wasn't as effective as he was hoping it to be.

Yet, rather than fixing her robe, she pulled it to the side, giving an even better view of her cleavage, including a lengthy glimpse of her areola, clearly trusting that his poor eyesight wouldn't distinguish between her skin and her beige bathrobe — which would have been the case if it wasn't for the convenient spell maintaining his sight.

Magic was not all battles and dark lords. Occasionally, it was fun.

"I can't believe he didn't return," she growled.

"Jealousy is an ugly trait," Harry commented, knowing exactly what to say to stroke her anger.

"Jealousy! How childish. Not like we have any thoughts like that. We're best friends," Hermione said. Harry could have pointed that the way her hand continued to play with the edge of her bathrobe, giving the occasional glimpses of her nipple — even if she was convinced that he couldn't see — undermined her argument.

He wasn't a moron, so he didn't say that. Actually, he didn't say anything, recognizing the signs of her growing anger, leaving her alone to stroke her anger further.

Fuming, she stood up and started walking back and forth in front of his bed, each angry step making the show even more beautiful, especially as, in her anger, she missed one important fact.

The belt was loosening further with each turn. Soon, her looks bypassed the line that split sexy and erotic, landing firmly into the latter territory. Harry found himself biting the inside of his cheek to prevent an extreme reaction.

He just enjoyed the show.

Hermione was furious. On the run from an oppressive magical government ruled by an actual dark lord, her definition of the crisis was rather expanded. Even then, however, she didn't expect an intense betrayal from her boyfriend, just because he was feeling jealous.

Yes, he was wearing the Horxclux, but so were they, and they didn't just leave after throwing a childish tantrum.

Just because he was jealous of Harry and her. Unbelievable. Then, she glanced to his bed, only to remember he was half-naked, with his surprisingly muscular torso on display — when did he start to work out, Hermione found herself asking.

Combined with her loose bathrobe, the scenario was not that unbelievable.

Good revenge, Hermione corrected herself immediately.

Though, even as the smug satisfaction hit her, she also felt a bit inferior. After all, the only reason she was able to do so was the absence of his glasses. He was effectively blind without them.

Just like that, her smile widened as she noticed a tube of lotion that she could reach. Why don't leverage the situation more, she decided as she sat on the edge of the bed once more, and pushed her bathrobe down, revealing her naked back to him, confident that, even in his state, he wouldn't see anything.

He would just realize that she was half-naked.

"H-Hermione," came a shocking cough from behind.

"Don't worry, Harry, it's not like you can see anything without your glasses," she said as she poured some lotion on her palm, and started rubbing against her arms. "I just want to finish preparation while we discuss what to do next, now that it's clear that Ron is not returning."

Revenge was beautiful.
