Nepgear walked back toward the other CPU Candidates, her legs wobbling. She had been absolutely shocked by what she had seen. It was the gas, she was sure. She couldn't let the others see what was going on behind that door, especially Rom and Ram. Nepgear didn't even notice the faint purple mist coming from beneath the door as she walked away. Rom smiled as she approached.

"So, how is it going?" she asked, that innocent smile covering her face.

"Um…" Nepgear said, trying to think of something to ay. "They...need more time, because...they're thinking of strategies to locate the plant, so we shouldn't bother them." she said.

"Why won't you tell us what it does?" Ram asked crossing her arms and frowning. "Why does it need to be a secret?"

"Because…" Nepgear said, glancing towards Uni, who raised an eyebrow. She didn't even know. "Because it's something you really don't need to worry about." she told her, and Ram pouted. Nepgear's thoughts were getting foggy, and she began feeling faint.

"Um, Nepgear? Are you okay?" Uni asked. "You're...swaying."

"Huh?" Nepgear said, as it got harder to keep standing and her vision blurred. She raised her head, which feeled like it weighed a ton, to look at Uni. Suddenly, as she laid her eyes on her, everything became blurred except Uni, who became crystal clear, and seemed to be glowing, like an angel.

"Uni...I…" was all she got out before she passed out.

Luckily, Uni acted fast, and she caught Nepgear before she hit the floor, giving a small yelp as her knees hit the floor hard.

"Nepgear?!" she shouted, shaking her, Nepgear shook and moaned as Rom and Ram rushed over.

"What happened?" Rom asked.

"I… don't know." Uni said. "Nepgear!" she shook her again, and finally, Nepgear's eyes fluttered open. Uni gasped as she looked into them. They...were glowing. Her eyes landed on Uni's, and they went wide, and a dreamlike smile came over her face. Uni looked at her in confusion as she raised a hand, and put it on Uni's cheek, and Uni gasped.

"You...are so...beautiful…" Nepgear whispered, stroking Uni's cheek.

"W-what?!" Uni said, blushing furiously.

"I think I'm in love with you…" she said.

"WHAT?!" Uni shouted, so surprised that she dropped Nepgear, who fell to the floor with a thunk. "Wh-what are you saying?! What has gotten into you?!"

"I think I've been in love with you for a while." Nepgear said, raising herself from the floor, into a crawling position. I guess I've never really been able to admit it to you or even myself." she said as she crawled closer and closer to Uni, who sat staring at her in shock as she blushed. Nepgear crawled closer, bringing her face up to Uni's, and whispered in her ear.

"I want to rip those clothes off of you and see your gorgeous body. I want to touch you all over. I want...to pleasure you." she said, her warm breath making Uni shudder. She leaned back, and forward again until their noses were touching.

"I want to become part of you." Nepgear said, before embracing Uni in a passionate kiss. Uni's eyes went wide as she let out a muffled gasp along with Rom and Ram.

"What is Nepgear doing?!" Rom asked in bewilderment.

"What do you think? She's kissing Uni!" Ram exclaimed.

"But, girls aren't supposed to do that!" Rom said, and moved round to try to pull Nepgear off of Uni, who was struggling to do the same. Ram soon joined her.

Nepgear broke the kiss, and grabbed the hem of Uni's skirt, throwing it up and off of Uni, leaving her in her underwear. Uni quickly covered herself with a squeal.

"What is happening?!" Rom asked, starting to cry. Uni kept trying to push Nepgear off of her, but she had become wickedly strong. She leaned forward again, and once again spoke in Uni's ear.

"I will make you moan." she said, and put her hand into Uni's panties, and started rubbing Uni's pussy.

"N-no! S-stop! Rom, Ram, look away!" Uni cried out as pleasure ran through her. But Rom and Ram didn't listen. They were too transfixed and way too curious.

"W-what are they doing?" Rom asked, blushing.

"I think...they're having sex. Or starting to." Ram answered.

"S-sex?!" Rom asked, blushing even harder. She had heard the word before, and knew it was something that married people do, so why was it happening now, with Nepgear and Uni? "Should we try to stop her?"

"I don't think we can." Ram answered. "She's too strong, for some reason."

Meanwhile, Nepgear continued to stroke Uni's pussy, moving her finger gently over the top of her clit, sending jolts through Uni's body, as she moaned.

With her other hand, Nepgear pulled off Uni's bra, tosing it aside, before squeezing one of her exposed breasts while she placed her lips on the other. Uni moaned, although she tried not to, as she continued to struggle, but trying less and less as the amazing rush overwhelmed her.

Nobody noticed the purple mist floating in.

"Hey, what's that smell?" Ram asked, sniffing the air. Rom tried to sniff the air as well, but couldn't smell anything, as her nose was stuffed. It surprised her she could still get a cold even though she lived in a place that was often cold.

Ram started to sway, and Rom tied to catch her as she fell, but she just fell on top of her. Rom tired to shake her awake, before realizing it was the same as with Nepgear, and she quickly scrambled away from Ram, who started to raise herself from the floor. Rom sat against the wall as Ram looked up at her, her eyes glowing, a smile plastered over her face. She crawled over to Ram and onto her.

"Ram, please...don't do this!" Rom pleaded, tears in her eyes. "We're sisters! We can't do this!"

"Yes we can, and we will." Ram said seductively as she forcefully grabbed Rom, who shrieked. She tried to get away as Ram ripped off her clothes. Rom cried.

In the other room, Blanc was sucking Noire's pussy, but paused as she heard a cry from the other room. It caused her to look towards the door, snapping out of her spell for only a moment, before Noire's hands on her chest pulled her back in, and she once again succumbed to the gas.

Rom continued trying desperately to get Ram off of her, who had practically ripped her clothes apart. Ram grabbed her hips and pulled her close, licking her lips, before pulling Rom's hips up and placing her mouth on Rom's smooth, hairless pussy. Rom gasped at the strange feeling that shot through her body.

"Ram, no! P-please, stop!" Rom pleaded, to no avail. Ram continued sucking her pussy, her tongue going inside it, making Rom cry out. Ram then pulled away, and Rom sighed in relief, but it was quickly replaced with more horror as Ram tore off her own clothes, turning around, putting her ass down near Rom's head as she started licking again. Rom gasped as Ram's own pussy came down to her face, right over her mouth. Rom shook her ass as she licked, and Rom, after trying to hold her breath, let out an exhale, and Rom moaned, making Rom look at her in confusion. Did the exhale on that sot make her moan? Rom didn't completely understand what was happening, but she knew it felt very, very wrong.

Ram pulled away from Rom's crotch. "Taste it. It tastes amazing. Or, at least you do." she said before resuming. Rom felt disgusted at the way she said she "tasted amazing". She resisted, though. But, Ram, not taking a no for an answer, squeezed Rom's sides roughly, making her cry out in pain, and, crying, she stuck out her tongue, and licked her sister's pussy. Ram moaned, and Rom recoiled at the strange taste, but she didn't want Ram to hurt her again, so she stuck her tongue back out, and continued licking, up and down Ram's small clit, making Ram moan and shake. The odd sensation of Ram's tongue inside her making her head swirl, and making her realize she had stopped struggling. She couldn't find the concentration or energy to do so, so she kept going. She kept licking, trying to ignore the taste. She then stuck her tongue inside, and Ram lurched, but Rom just ignored it and continued.

They both got faster, starting with Ram, and Rom following her lead. She felt something building down below, and soon, Rom lurched and shuddered as she felt something shoot out from her crotch, which Ram licked up, and soon after, Ram's pussy shot out a hot, sticky, clear substance, which Ram couldn't stop from coming into her mouth. She choked and sputtered as Ram got off of her. She looked up, and found the three of them staring at her, Nepgear now also naked next to Uni and Ram.

"U-uni? Are you…?" Rom started to ask, before they started to walk towards her.

"N-no...no! NOOOO!" Rom screamed as they descended onto her.

A few hours later, the CPUs opened the door, crawling out, exhausted and covered in fluids and sweat, and found the Candidates in the same condition.Each went to their siblings, and Vert looked over to see Rom curled up in the corner of the room.

"Rom?" she asked softly, and came closer. She saw that she was shaking. She grabbed her, and shot her hand back at the stickiness of Rom's body, before reaching back, and turning her over. She was shaking like crazy, her eyes wide and staring off at nothing, unfocused and empty, tear staining her cheeks, and bruises covering her body.

"Rom!" Blanc shouted, hurrying over to her. "Rom, are you okay?!" she asked, grasping her cheeks. Rom recoiled at her touch. She turned towards the Candidates, a burning fire in her eyes.

"I-I don't think she was affected by the gas." Nepgear said quickly. "I don't think she was affected because she didn't inhale it, or at least not through her nose, which seems to be what you need to do, due to her cold, so she wasn't in the same state as we were. So, she had to experience everything while lucid, and, as I'm sure you know, it can get pretty...violent…" she said this as she looked down in shame and sadness.

"Blanc ran over to the main door to the hallway. "We need to find this plant and whoever took it so I can rip them apart!" Blanc bellowed. She grasped the doorknob, and tried to turn it, but it didn't budge. She tried again, pulling with all the strength she got from her anger, to no avail. In pure rage, wth her remaining strength, she yelled and punched the door, leaving a crack.

"Blanc! What's wrong?" Vert asked. Blanc turned towards them.

"The door's locked. We're stuck in here."
