When Kazuma first heard someone rummaging around in his bedroom in the middle of the night, he assumed it was Alderp sending someone to get some payback for crashing his wedding and stealing his would-be bride. Either that or Aqua thought he had some food hidden in here and was trying to steal it from him. Whoever it was, they had clearly never put a single point into stealth in their life. They might be trying to sneak, but they were making so much noise that half of Axel had to be awake by now. It couldn't be one of Alderp's men; he might be a greedy, corrupt slime, but he couldn’t have hired anyone this incompetent.

“Do you have negative points in stealth?" Kazuma asked, sitting up in his bed. He heard a gasp of surprise from whoever was trying to sneak in, and he wasn't going to give them a chance to recover. He quickly used his Tinder skill, summoning a small flame. It was too weak to be used as offensive magic, but it would let Kazuma see his target clearly, and then from there, he would decide what he would do next, depending on who this was. "I don't—uh, ah, D-D-D-D-D-Darkness-san?!"

As far as Kazuma was aware, Darkness was planning to spend what was supposed to have been her wedding night at her recuperating father's bedside, but it wasn't her returning to the mansion in the middle of the night that made Kazuma scramble back on his bed until his back and butt were touching the headboard. The true reason he was so shocked was that Darkness was standing in his bedroom wearing only what he assumed she had been wearing beneath her wedding dress. She still had the white veil and long gloves on, but other than that, she was down to just a tight white corset that her boobs were trying to escape from, white stockings, and pristine white panties that he tried very hard not to look at for too long. In short, she looked the part of a new bride ready to spend her wedding night in her husband’s bed.

And she was standing in the middle of Kazuma’s bedroom.

“W-what are you doing in here, Darkness-san?!” he asked. “A-and dressed like that?!”

“Have you forgotten already, Kazuma?” Darkness asked. “You bought me. I was supposed to get married today, but you bought me.” Her cheeks were flushed, she was panting, and he could even see a little bit of drool dripping out of her mouth.

“How could I forget that, you perverted Crusader?!" Kazuma said. "Your masochism struck at the worst possible time, and I had to carry you out!" Darkness giggled and closed her eyes at the memory. Clearly, the reminder of the trouble she'd caused him was not helping. "A-anyway, I only bought you so you wouldn't have to marry that pig lord! That’s it!”

“You said I was going to have to earn back every last coin with my body,” the noble girl said. She might be from noble stock, but the look on her face as she relived that moment was anything but noble or dignified. She was trembling, but not out of fear. The lewd knight looked like she was about two seconds away from sticking her hand in her panties and masturbating frantically. This wasn’t good.

“I meant you would earn it back through adventuring!” he said, looking quickly toward the door out of fear that Aqua or Megumin would happen to be there to hear her say that. “You know I’d never make you do anything like that, you masochist!”

“But what if I want to repay you with my body, Kazuma?" Darkness said. She walked toward him, and Kazuma gulped as she climbed onto his bed, got on all fours, and turned away from him. Her ass was to him, and with her wearing nothing below the waist but panties and stockings, he could see a great deal of that ass. This was getting more dangerous for him by the second.

“There’s nothing to repay, Darkness,” he mumbled weakly. His dick was already reacting in the only way it could, given the situation, and he knew that he was seconds away from pouncing on the perverted Crusader unless he shut this down now. “You’re free now.”

“Then I choose to give myself to you,” Darkness said. She hooked her thumbs in the string of her panties and slid them down her legs, displaying more boldness than Kazuma had believed her capable of. “I want you to use my body on my wedding night, and every other night. It’s all yours now.”

“You like that, you horny knight?!” Kazuma asked, giving Darkness another spank immediately after he’d driven his dick as deep inside of her as it could go yet again. She squealed in delight, just as she had every time he’d spanked her, thrust into her, or pulled her ponytail. For being a virgin, she didn’t have any problem getting rough right away.

The same applied to him, he supposed. He’d been just as much a virgin as she was heading into tonight. Losing his virginity with Darkness tonight had not been part of any plan that he’d drawn up when he set out to rescue her from her unwanted marriage, but her sexy body and her perverted thoughts had been more than he could take. He didn’t get into his own head about this being his first time, and he didn’t worry about Megumin or Aqua hearing them going at it, either. Kazuma was too far gone to deny any and all accusations they might make about his perversion now. Fucking Darkness felt too good for him to think about whatever the fallout might be within the party.

“Yesh!” she cried. “Ish sho fucking good, Kazuma! Keep rutting me! Use my body!”

The masochist’s dirtiest dreams were coming true, and hearing her speech slur as he fucked, spanked, and taunted her to the point of stupefaction only made Kazuma move his hips faster and slap her ass harder. He’d always figured that, her obvious fascination with debasement, pain, and humiliation aside, she would not be able to see it through if the opportunity ever came for her to genuinely be fucked like a slut. How wrong he was about that. Darkness was having the time of her life getting fucked on all fours like a bitch while wearing her white bridal veil, stockings, gloves, and nothing else.

Kazuma ceased the taunting and dirty talk toward the end, choosing to instead put everything he had into pounding Darkness hard enough to make the headboard slam against the wall. Between that banging, the loud smacking of flesh on flesh, and Darkness' squeals of utter delight, Kazuma didn't see how it was possible that Aqua and Megumin hadn't heard them by this point. But for whatever reason, they were staying away from Kazuma’s room and allowing him to fuck the party’s masochist knight unimpeded.

He kept hammering her with brute force thrusts, not sparing a thought for technique or pacing himself. The last thing in the world Darkness wanted right now was for him to start holding back. She wanted to get treated like a piece of meat, like a fuck toy whose only purpose was to have a dick ramming balls-deep in her pussy while she squealed, and Kazuma the pervert was giving her everything she needed. The only difference between her masochistic fantasies and the reality of their rutting was that rather than truly treating her as nothing but a sexy body to be used, Kazuma viewed her as a trusted teammate worth selling off his inventions and his earnings to save.

That was out there, though. In his bedroom, Kazuma was now prepared to give Darkness all the perversion she’d been dreaming about. She squealed again as they came together, Darkness’ pussy squeezing Kazuma’s dick and making him grunt as he erupted within her and filled her with his seed, not caring about any risk that the unprotected creampie carried.

It wasn’t like this was going to be the last time he shot a load inside of the lewd knight, anyway. If she was serious about giving her body to him every night, their mutual perversion was only beginning.

A/N: Having scaled back to just 1 or 2 birthday quick fics per month as opposed to the minimum 4 per month that I did in 2024, there will be more time for me to try and do multiple parts of Everyone Wants Harry every month. In addition, I'll be able to write whatever random ideas pop into my head, like this one, which is the result of me recently having finished the third season of the Konosuba anime.
