Story: Curvy Usagi

The arcade had gathered quite the crowd, but it wasn't because a hot new game was being installed. That is, unless you count the inevitable contest between two buxom babes in a dance off as a game. The two of them were standing there like mirror images of each other, a hand confidently on their hip while they stare a hole clean through one another, one foot tapping impatiently, waiting for the beat to drop while the crowd watched with bated breath.

Then the beat does finally drop. The two start to dance, strutting their stuff and aggressively bouncing their butts around as they step on their squares. The crowd erupts into cheers as the contest begins, Ami among them. It defies her wildest expectations, and probably a whole lot of other people too. She knew it would be hot, she knew it would be super erotic, but this... this defied her wildest expectations.

It was as if her eyes didn't know where to focus to find the yummiest treat. Would it be their thighs? Their glorious thick thighs that looked as soft and comfortable as any pillow? Would it be their shapely butts, where each cheek promised a taste of heaven if only you'd get on your knees and plant your lips on it in righteous reverence? Perhaps their trim tummies, or their wide hips which were so appealing you could almost taste the dopamine rush? Oh, or maybe it would be their breasts, their wonderful chests that were bouncing around barely restrained... She honestly couldn't tell, each part of their bodies were equally perfect. And there were two of them!

"Uuuugn..." Rei grunted. "Wish I had a little sister like that!"

"Me too!" Makoto whined in agreement.

Funny, now that they mentioned it... Ami sort of wished she had a big sister that would spoil her rotten. She could see it so clearly, it was almost as if she was taking the place of Usagi's opponent. Her big sis. Akemi Mizuno. A glasses wearing girl, refined, tall, busty and a little bit of an extrovert, but not too much. She would shower Ami with love and affection and tell her random trivia, and play strip chess with her and they'd shower together and -

Beep. Beep. Beep.

It was an experience like breaking the surface of a swimming pool, the illusion popping away like a balloon. That beeping sound was coming from the Mercury computer. That was the alert for when there was a significant energy drain happening right where she was. Sh-She should use the computer to -

Boing, boing, boing, boing.

Booty, boobies, booty, boobies... Ami found herself panting shamelessly, and only now did she realise where her hand was right now. In her panties. Her soaked, drenched, thoroughly <i>ruined</i> panties. Her free hand was trembling too, she reached around and found her pen, then tried to say the transformation phrase.

"Slutty big sister Mercury," she said. No, wait that wasn't it. Suddenly, and quite without warning, Usagi and her opponent both bent over to use their hands to touch the left and right arrows on their mat at the same time, thrusting out their butts. The next thing Ami knew she was fellating her transformation pen. It was hopeless. She'd been exposed to Usagi's sexy curvy body the longest, her ability to resist was eroded down to nothing. The only hope now was if her friends were able to resist.

"Big sis Rei, you look so cool today!" Minako said.

"Oh, little sis Minako, you're far too kind," Rei replied. And at the corner of her eyes she could see the two start to sloppily make out. Was this a good time for Ami to catalogue her knowledge of curse words across all the currently living languages on the planet Earth? Probably not. She did so anyway.

"Little sister Ami, your breasts are so nice," big sis Makoto said. Big sis? Ah! She felt big sis's hands sneak around to play with her breasts, while her own big boobs pushed into Ami's back ."But you still have a way to go before you match your big sister."

That said, the Senshi were far from the only people affected by Sister Complex’s powers. Many visitors of the Arcade had gathered in curiosity, only for them to end up staring in shock. Not to mention a number of girlfriends trying to drag their boyfriends away from this perverted show.. only to end up staring themselves as the melody sped up and the two blonde’s started pushing their breasts together as if trying to smother an invisible (and very lucky) person between them.

“Ahh.. Onii-chan, I am so wet, please hold me.” Not to mention that this little incest fetish was spreading like a wildfire. Girls were starting to look at each other and the boys present in undisguised lust. Boys were similarly feeling all manner of questionable things, not to mention a few people with actual siblings were going to have an awkward time when they got home.

On the good side, a number of relationships were going to improve a lot due to some sister-brother roleplay.

"Wow, this is working out way better than I expected," a sinister voice giggled nearby. "She's already driven everyone into an actual honest to goodness sister complex induced orgy. The energy readings we're getting are off the chart! And there's absolutely nothing that anyone can do to stop it! Ohohohoho!"

"Thank you! Thank you so much!"

That was the voice of the one and only person who was seemingly unaffected by the sheer hotness going on, onstage. Ami looked over. She didn't stop frenching Makoto or anything, but she did look over. In large part so she could see those butts/boobs/hips/legs in action again.

What she saw was Shingo rushing over towards Usagi's opponent, apparently oblivious to the rampant fornication happening all around him, and shaking her hand with so much enthusiasm you'd think he'd met a world leader.

"It's such a relief," Shingo sniffed, tears flowing down his cheeks. "No more torment! I look at her, and you know what I feel? <i>Nothing at all!</i> Absolutely nothing!"

"Wait, what, you're not turned on by your sister, but you are turned on by me?" the youma asked. Yes, that made sense. Of course! Ami realised it all now, Usagi's sexy opponent was the youma in disguise! "But... But I'm Sister Complex! I make people hot for their sisters, then feel really weird about it! That's my whole thing!"

"Oh shit," the apparent leader whispered to herself. "I made her out of that boy's confused feelings over his super, duper, nuclear hot sister. Which means he doesn't currently feel <b>anything</b> towards that odango headed fuckslut. That in itself is a crime against nature, but for a being like Sister Complex..."

"But little brother! I'm such a hottie, aren't I?" Sister Complex said, adopting a really over the top sexy pose for the boy.

"Yeah, you are! And you're not my sister so I can stare all I want! Hahahaha!"

"Hey, wait a second here!" Usagi stomped her foot. "I was about to win, you dork! Quit interfering in my - Oh wow, that's a lot of people doing dirty things to each other." Ten whole seconds pass by. The gerbils running in their wheel in Usagi's brain finally turn it enough, and she pounds her fist into her hand. "Oh dear I have to go to the bathroom be back in a second and <i>no perving on my friends!</i>"

"Sister Complex, ignore the boy! You literally can't make him feel anything right now!" the youma's boss yelled out. "Focus on the rest! Drain 'em dry, and make 'em all hot and horny for sisters they might not even have!"

"But booosss! My little brother isn't treating me right anymore," Sister Complex whined. By now holding onto him and all but grinding all over him.

"Unhand that dorky little brother!" Sailor Moon yelled, striding into the room and... Guh! Ami nearly swallowed her tongue. For that matter, she almost swallowed Makoto's tongue. Sailor Moon in all her glory, curvy as all get out was not something you dropped onto an already horny room if you wanted to help them regain self control!

“Nooo! He is mine, I need to make him see me as a sister!”

"Well, you're not his sister! You're a youma!" Sailor Moon said, shifting poses to point dramatically at Sister Complex. "And I'm here to give you a good hard spanking."

"Hahahaha! That's super hot too!" Shingo laughed. "And since you're obviously not my sister, it's okay to perv out about you too! Get her, Sailor Moon!"

You know, a thought occurred to Ami just now. Maybe she ought to try to get her parents to hook back up? Or maybe remarry? Preferably someone with, you know, a cute daughter? It couldn't hurt. Couldn't hurt at all...
