Story: UY Authority Badge

 The relationship between Lum and Ran is an unusual one, even in the context of the setting. On the surface, Lum and Ran appear to be childhood friends from their home planet. However, beneath that veneer lies a tangled web of rivalry, resentment, and affection that reflects both characters’ exaggerated personalities and the series’ broader commentary on friendship, jealousy, and emotional immaturity.

From the outset, their bond is defined by contradiction. Lum is outgoing, impulsive, and sincere. These are qualities that make her both endearing and exasperating in equal measure. Ran, in contrast, is more manipulative and vengeful, often masking her true feelings behind a saccharine façade. Much of their relationship revolves around Ran’s enduring grudge against Lum, which dates back to their youth. Ran blames Lum for various childhood humiliations, ranging from trivial embarrassments to more substantial betrayals (at least from her perspective). Yet, even as Ran vows revenge, she continually seeks Lum’s attention and approval, suggesting a deep-seated emotional dependence that undermines her hostility.

What makes their dynamic especially distinctive is that their antagonism never fully erases the traces of genuine friendship between them. Lum, for all her obliviousness, often treats Ran with unguarded affection, inviting her into social circles and forgiving her repeated attempts at sabotage. Ran, meanwhile, is torn between her bitterness and a nostalgic attachment to the comfort of their shared past. Their interactions oscillate between tender camaraderie and slapstick hostility, embodying the emotional volatility of adolescent relationships - only amplified by alien technology and supernatural chaos.

So how, exactly, is Lum supposed to react when two things were true at once?

1: She was about to take it up the ass for the first time with her Darling.

2: Ran was standing in their room, being all submissive and - for good measure - wearing a maid uniform.

"Oh, what's that you say?" Ataru chirped happily. Already, Lum could see the direction this was going, and she didn't like it very much. "You're here to serve, are you? Tell me more please~"

Ran curtseyed. Oh no, she was adorable like this. What was worse was.... Lum knew there wasn't any attempt at manipulation or deceit here, because her reward for the day was that Ran would not hate her anymore. But she was antsy and eager to give her Darling his reward - an entry into the glorious world of anal.

"Oh, I've been simply awful to Lum for such a long time!" Ran sighed, putting the back of her hand to her forehead, feigning a swoon. "She doesn't deserve it. No, indeed, she does not deserve even an inch of that treatment. Therefore, I shall endeavour to make it up to her in any way that I can."

"That's really quite wonderful," Lum said, already behind her and pushing her out the door to the room. "Help mother make dinner if you're so eager to serve!"

With that, she closed the door, turned around and gave her Darling a withering look. "Darling," she said. "I want your penis in my butt, and I want it there a minute ago." He tried to say something. Anything at all. "Forget about Ran, for the moment. I'll let you fool around with her after we're done, but for now? Stick it in my anal cavity, and -"

"If you're going to be having anal sex, make sure to be careful," Ran said. She was holding a bottle of lube. How did she - huh?! "Those that don't know what they're doing tend to hurt themselves the first time. Lubrication is especially important. Allow me to -"

Lum grabbed the bottle from Ran's grip, and pushed her out the door again, and then for good measure pinned it shut with Darling's desk chair. How did she - Never mind. Darling was already taking off his clothes.

"Can we have a threesome after this?" he asked, sounding hopeful. "You, me, Ran?"

"... Fine!" Lum said. Her need to have his dick in her butt was pretty much all consuming at this point. She understood rationally, it was his payment for good service today - but it didn't stop her need to actually do it. Besides which, it would bring her closer to Darling. Anyway. She ditched her uniform, and her bra, then upended the bottle of lube over her naked chest.Where other girls would drop to their knees so they could do what she was about to do, Lum just had to tuck and float over there, catching his shaft in between her boobs so she could properly - 

Some of the lube dripped onto the floor. Lum caught a flash of pink in the corner of her vision, and the sound of cloth rubbing into floor.

"Pardon me," Ran chirped. She was on her knees as well, a piece of cloth in her hand as she was cleaning up any of the excess lube that had dripped down onto the floor. "Don't mind me. Give it to her up the butt without paying me any mind! Might I suggest being gentle at first to make sure you don't tear anything?"

"How do you know so much about anal sex?" Lum asked.

"I read a lot of spicy material!" Ran chirped.

The things that she was learning about her old friend today. Lum shook her head and turned to the door. The chair was still in the way. How was she - 

"Ohhh, space time corridor in the closet!" Lum said, slapping her own forehead. Then she grabbed Ran's arm. "Pardon me, this is something we need to do in private, and - "

And then she felt a pair of hands at her hips. Something was poking at her. Right in the valley between her cheeks. She still had her bikini bottoms on, but - But Darling had a pretty good grip of her. Lum's breathing hitched. Anticipation spiked.

"Let her stay," Ataru said. "She's right, we wouldn't wanna hurt you the first time, right?"

Drool started to pour from the sides of Lum's mouth as several facts collided in her head. She needed to. Had to. Reward her Darling by taking it up the ass. But. Dinner would be ready soon. The more time they took getting rid of Ran, the likelier it was they'd be interrupted before they were done. And yet. Ran was coming back into the room. And yet. Darling had a good hold of her right now. If she shocked him, he'd be in no condition to - Oh, she couldn't shock him anyway, and so -

She was trapped. She didn't want Ran in the room when she was having some form of sexual fun with Darling. It would be so embarrassing! But - But she had no choice, did she? If she was going to get fucked in the ass, she'd have to - His fingers had shifted. Gripping her bikini bottoms. Pulling them down. Lum found herself bending over. Putting her hand flat against the closet door. And then- And then?!

"Don't ram it in," Ran warned. "Guide it in gently. Give her time to adjust. Your member is slightly larger than the human average, in both girth and length, so -"

It was inside her. She could feel it snaking in, assisted by the lube that her titjob had slathered over it. Lum's eyes were already rolling up into her head as it was, but now they were also starting to cross for good measure.

If anyone tried to take this away from her right at this moment, they would have eaten more electricity than it takes to power Japan for a day.

======

This was going great so far! When he'd found Ran waiting for them in the maid uniform, Ataru had been so excited! Even if Lum didn't seem to be. Hehehe! This is it, this is his first step towards building a harem!

Second step? He was already having sex with Lum each night now, and based on today she seemed a bit more receptive to sharing...

"Keep you pace slow," Ran admonished when he tried to move a little faster. "You don't want to hurt her, right?"

Of course not. Ataru grinned to himself, revelling in the moment. He pulled one hand away from Lum's scorching hot bod (which was a Herculean task) so he could goose Ran. She didn't seem to mind at all. If anything, she moved closer to him, and - And there was a threesome coming along for sure!

The harem was growing. Two girls now. Lum, who was increasingly eager to please him. Ran, who was his pretty pink haired maid. She was still guiding him on proper sexual etiquette for anal sex, which was super helpful because the responsible thing to do in this situation was to ensure Lum was not hurt.

Responsible. Responsible. He had a responsibility to his girls. For Lum, he had to repay affection with affection. For Ran, he had to make sure he did not take advantage of her willing servitude, know his limits. After all, they were making him feel so amazing, right? It was only right that he do his best for them as well! That was the responsible thing to -

He suddenly realised what he was thinking and felt a little disgusted with himself. R-Responsibility? This wasn't about being responsible, it was about having -

Before the thought could finish, he nutted inside of Lum. Her mouth made a happy humming sound, while her butt muscles clenched around his shaft, milking him dry and making him collapse from happiness.

"Now, it's vitally important that you wash up when you do that sort of thing," Ran said. "It's very easy to catch infections, and the last thing you need if you have vaginal sex with her is passing on something from her anal cavity into her pussy. It would be quite irresponsible of you."

Right. Ataru took a gasp of air, suddenly aware of how intense that had been. He... Shouldn't be entirely irresponsible, right? After all, that's how people get hurt. But then again, if he winds up becoming too responsible, then - 

He turned his head to look to the floor, where the authority badge lay. It was mocking him. Absolutely mocking him. It was going to make him responsible, by hook or by crook.
