Smut this chapter. Sorry. It's Gironatsu smut though.

So if you don't like smut please just skip it.

Three months had passed. They were all attempting to stay sane with their imprisonment.

Each of them hoped for the day Tamama, Angol Mois, or Aki would knock on the base door to get in. But it never happened.

Nobody ever knocked.

Sometimes Natsumi felt that they were dead, that they were truthfully the last ones left, but she knew she had to hope for the best.

Hope was all they had, after all.

Luckily, after three months, things had progressed into steady regulation for them all. They all had normal things they did everyday, and they were beginning to find a rhythm to their new lives.

I'm going to confess to Saburo, Natsumi decided. She had gotten closer and closer to her crush throughout the days. They had made causal small conversation almost everyday.

She knew eventually they'd probably be together. The odds were in their favor! They were two out of four of the last humans alive. They'd probably get married and have like a million kids.

I'll tell him tomorrow. She forced confidence into herself. She needed to set a date so she didn't chicken out. She could tell him of her feelings. She really could!

She wasn't the only one hoping to confess her feelings tomorrow, though. Koyuki was, as well. She watched Natsumi from afar. We're two of the last humans left. I'm sure I can tell Natsumi how I feel. Tomorrow would be a perfect time. They had an entire lifetime ahead of them. And Koyuki was ignorant of the love rivals.

Natsumi nodded to herself thinking about Saburo. She had no idea of the feelings her best friend had for her.

Keroro was thinking of more important things than confessing, unlike Natsumi. Three months had passed.

"They're not coming back on their own," Keroro told his platoon quietly. Dororo nodded, finally seeing Keroro's point.

"We can't leave them out there. We have to find them. And just like I promised, if you won't go out with me, I'll go on my own," Keroro insisted.

"I won't let you," Dororo told him, putting his hand on Keroro's. He smiled at his friend. "We're a platoon. We go together."

"We won't leave a man behind," Giroro agreed finally. "We either need to retrieve the body, or save him from whatever occurred out there."

"The atmosphere should be doing better after three months," Kululu reported. "Give me a few days and I can make radiation suits for us. They should buy us at least a little time. And as I said before, we shouldn't die out there. We're Keronians, not Pekoponians. We'll react differently to the radiation."

"Still best to be safe, right?" Giroro shrugged. It was just an average field mission. They just had to be quick about it. "But we shouldn't bring the Pekoponians."

"They'll die, unlike us," said Kululu.

Keroro grinned at his platoon. "Thanks for coming with me, guys."

"It's been three months. Waiting any longer would be idiocy. It's clear that he's not coming back on his own, and we have to help our platoon member out," Giroro nodded. He wanted to be by Natsumi's side, but he knew he couldn't betray his platoon.

"I wanted to go out for them the very first week, if you remember correctly. Ku. I wouldn't leave you to do it alone." Kululu offered support too.

"We're friends. Nobody should be forgotten about," Dororo smiled warmly. Keroro hugged them all.

"How long will it be until the suits are done?" he asked Kululu.

"One week. We should say our good-byes to the Pekoponians just in case something goes wrong, but it'll only be one more week of waiting," Kululu told him.

Keroro nodded. He could last a week.

They held a meeting for the Pekoponians. "We'll be leaving in a week to locate Mois and Tamama," Keroro told them. "We'll be fine. We'll have radiation suits that should protect us for a little bit. But... you won't be able to come with us. Our bodies are built differently than yours. We'll deal better with the atmosphere out there. You would die out there, we wouldn't," he explained. "We'll be gone for a bit, but I promise we'll be back soon!"

The Pekoponians listened and nodded. They didn't doubt Keroro's words, but some were a little worried. Namely Fuyuki.

"Sarge..." Fuyuki threw himself on Keroro in a hug. "You promise you'll come back?" he asked. "Pinky swear?"

"I promise," Keroro grinned, putting his pinky around Fuyuki's. They shook pinkies.

"You... won't get hurt like Momoka, right? And when you're back, we can research the occult, right?" Fuyuki asked.

Keroro nodded. "And maybe Tamama knows what happened to Momoka," he told Fuyuki. "Maybe we'll get lucky? Who knows! Maybe he's even hanging out with her and that's why he's not with us."

Fuyuki grinned. He hoped so. That would be the ideal situation.

"I hope that's the case," he said. "I miss her."

It was the most hopeful he had been for a while.

Saburo and Kululu said their good-byes, too.

"So you'll be back soon?" Saburo asked Kululu while Kululu was working.

"Ku. I should be," he said, then bragged, "After all, I'm the one we keeps this base running."

Saburo looked off to the side. "Be okay, all right? You don't have to go, you know."

"Ku. Is that concern you're expressing for me?" he joked. Saburo grinned and rubbed the back of his neck. "And I do have to go. We should have gone a lot sooner for them."

"You know, I could tease you at how much feeling you're expressing for missing her..." Saburo teased. "But I won't. As courtesy for the worst case-scenario that I might not see you again, you can stay in your denial."

Kululu glared for a moment. "I would do the same for you if you were out there. It's not anything special. I just need her to help with communications."

"Dude, there's a pile of broken cell phones that you dialed with her number constantly. You've been beyond worried for her. You probably would have called me a last cause, being a Pekoponian, but you're still holding out hope that she's fine," Saburo called out.

"Sh-she is," Kululu stuttered.

Saburo shrugged. "Yeah. That's why you'll find her. That's why you're going out." He smiled. "Just be safe, okay?" Saburo asked.

"Don't get sappy on me," Kululu groaned. But he was thankful for Saburo's words, anyway.

This was a mission. And the end of the mission wasn't absolute. As a mission, Giroro had to treat it with the possibility of its worse-case scenario. He knew deep down he might die on this mission.

He might never return. He knew Keronians and Pekoponian biology was different, but that still didn't mean they wouldn't die.

He had said his good-byes to Miss Furbottom, it was Natsumi's turn.

You've got to act like this is one of your last days alive, Giroro, Giroro told himself. After all, he didn't know if it was one of his last days.

He needed to tell Natsumi how he felt. If he didn't, his relationship with Natsumi would pretty much end, because even if he did return, it was likely that Natsumi would hook up with Saburo while he was gone.

He passed by Dororo's garden and picked some of his flowers again. He needed to be confident.

Natsumi would either reject or accept him, and out of respect most likely she'd wait at least a little bit to get together with Saburo.

He knocked on her door in the base.

"Yeah?" she asked, opening it up. She saw Giroro standing in front of her door with flowers.

"Umm here." Giroro handed her the flowers. She wanted to ask what they were for, but she knew he was leaving soon, so she let him into her room to talk to him.

"What... What do you need?" she asked. Maybe he just wanted to talk. To say good-bye. She could understand that. She would miss him, too. She really hoped things went smoothly.

"I wanted to tell you before I went out how I felt. In case I die out there," he started.

Natsumi was confused. "How you feel?"

"I..." Giroro blushed. This was the moment he had waited for for an incredibly long time. "Since our very first fight, the one where you punched me out a window, I've held strong feelings for you," he confessed. "I know you're in love with Saburo, but I would like you to at least consider the option of us... But if you don't feel the same way, I'll respect that." He nodded.

"What are you talking about?" Natsumi was very confused. She didn't even know what Giroro's strong feelings were.

"I... I am..." Giroro cleared his throat. "I'm in love with you, Natsumi."

Natsumi's mouth opened in utter shock. She hadn't seen that coming at all!

Giroro awaited her response. But she was just in utter shock. She hadn't experienced this level of shock since the bombs had fallen.

"Wh-what... What do you feel?" Giroro asked, licking his lips a bit in nervousness. His hands twitched.

Natsumi shook her head, trying to wake herself up. Did she feel the same? She was in love with Saburo to her knowledge, but Giroro... She was incredibly close to him. He understood her, she felt at peace with him. She felt whole with him. And she certainly shared a lot more interests with Giroro than she did with Saburo.

Unlike how Saburo was a passing crush, a hot guy, she could realistically see herself having deep conversation with Giroro, having fun every day with him. She could even see herself kissing him, now that she thought about it.

"I... I don't know," she admitted. "It's a big thing. Love, that is," she realized. "I can see us together. I really can. I know I like you. You're really cool. But I just don't know... if what I'm feeling is love yet," she confessed.

Giroro nodded. "I apologize for putting you on the spot. What you said was good enough, though. It's just that honestly I don't know if I'll survive going out there. I hope I will, but I wanted to prepare for the worst and tell you before it was too late," he told her.

"I have a few more days before you go though, right?" she asked. "I'll figure out how I feel before then."

Giroro smiled. "Thank you."

Natsumi nodded as he left her alone.

Koyuki was outside Natsumi's room. She had been prepared to confess to her. After she heard Giroro's confession, she felt it wouldn't be a good time, though.

She felt sad. She knew Giroro felt the same way about Natsumi, but Natsumi would probably choose Giroro over her as a romantic partner.

"You okay, Lady Koyuki?" Dororo asked, as Koyuki watched him water flowers.

"Giroro confessed to Natsumi. I... I decided not to tell her like I planned because I don't want to overwhelm her," she confided.

"That was very nice of you," Dororo complimented. Koyuki had great judgment. Koyuki was silent for a few minutes, a bit mopey.

"You'll be safe, right?" she asked, finally referring to his journey to the outside. She didn't want to lose him. He was her best friend, and her steady rock.

"I don't know, Lady Koyuki," he admitted. "But I can't just leave someone alone. Being forgotten about... hurts."

"I'm worried for you, though. What if something goes wrong?"

"Even if something goes wrong, I will always remain alive in your heart. There is no way to separate us truthfully. We're soul mates," he reminded her, grasping her hand and smiling. He took some string off the ground and tied it around Koyuki's pinky and his own. "This string, metaphorically and literally, ties us together. Even if we're far apart, we'll be together in our souls," he reassured her.

Koyuki smiled and hugged him. "Come back soon. Promise you'll come back to me soon."

"I'll always be with you. Do not worry." Dororo hugged back. He was glad he could share moments like this with her.

They hugged for a good long while.

There was one more day left until the frogs would leave. And Natsumi had thought long and hard about the Giroro issue. She had originally planned to confess to Saburo, but she felt like she no longer wanted to.

It had taken her a few restless nights, but the thought of Giroro dying out there worried her. He was a piece of her in a way. They were whole together.

She didn't want him gone. And she realized that was why he told her how he felt. He wanted to wrap things up between them before it was too late.

"Giroro." She didn't even knock on his door, she just threw it open.

"Natsumi?" He looked at her, wondering if she was ready to talk.

"I... I love you," she said. "I don't want you out of my life. I don't want you gone. But if there is a risk of you dying out there, I want to make things right between us before you leave."

"It's very unlikely that we'll die, from what I've heard from Kululu," Giroro explained to her. "I can just focus on the mission better if I treat it as such." He explained his weird logic.

Natsumi sighed, a bit relieved, but her hand still found its way to Giroro's. She smiled at him.

"I'm... glad you feel the same way. I can't tell you how relieved I am," Giroro said, grinning. "And happy."

Natsumi smiled. It was cute to see how happy Giroro was. She leaned down and kissed him on the lips.

Giroro melted. She could feel him tense up in embarrassment at the kiss. She giggled a bit. That was even cuter.

"If... If you really want to treat this like your last day to focus on the mission better, I wouldn't mind. What would you do with me now that I'm your... girlfriend I assume?" Natsumi asked.

Giroro beamed. "G-girlfriend? You're my girlfriend?"

She nodded. His embarrassment really is the cutest! "What would you do with me?"

"Kiss you all day. Hold you," he confessed.

Natsumi frowned. That was less than she had expected, less naughty and less of a "last day alive" kind of thing. It was cute, though. She could admit that much.

"Anything else?~" She asked rather flirtatiously. She wanted to enjoy the time with Giroro she had. Also, her imprisonment in the base didn't offer many new things for her to do. Having sex with Giroro before he headed off on a mission would offer some much-needed fantasies to her and would be a very enjoyable memory. Even better, it meant that when he came back, more would probably be promised in the future.

"Hmm... I'd take you on a date!" Giroro smiled triumphantly. Natsumi sighed.

"I meant if you'd make love to me if it was your last day alive?" she asked, rubbing her forehead. He was not getting the clues.

She was horny and proud, goddamn it. And realizing how much she cared for Giroro made her very much want this to happen between them.

Giroro turned completely red. He started wobbling as if he was about to faint. "Ummm... well, I mean that's a good way to spend a last day, too... And I mean, that would be a perfect way to say good-bye for a bit. But, w-we just got together! Do you really want to start our relationship like that?"

Natsumi nodded eagerly. "We have plenty of time here, from what I've heard. When you come back, we'll continue having plenty of time. I want to value the urgency we have now, instead of being boring and patient."

Giroro blushed. "Well then... I see no harm in it." He carefully closed the door that Natsumi had swung open, blushing. He seemed to be trying to figure out what to do.

Natsumi rolled her shirt off of her, slowly. Giroro looked over at her, glancing sometimes at the wall when he felt embarrassed and had forgotten that he was supposed to be looking at her. Besides that, she had his complete attention, though.

"You're supposed to be looking at me and touching me, Giroro. You're treating this like your last day, remember?" she reminded him gently. She knew bra technology was probably too advanced for him, so she released her breasts on her own.

Giroro was entranced by the tiny bounce they made as she tossed her bra onto his floor. This was like so many of his fantasies and dreams.

"Come here," he begged. She did, and he placed his lips against hers passionately. Sucking on her lip, but being gentle not to bite it too much with his very pointy teeth, he eventually got a moan from her.

She placed her hands on his butt and tried to get him to grind a bit against her stomach as he passionately kissed her lips, his tongue eventually entering her mouth.

Their breathing became heated and he drew away from her, his eyes half-lidded. "I'm sorry, Natsumi, but grinding against your stomach is just too awkward."

"Sorry. I never put much thought into size differences before," she admitted. She had fantasies about this happening with someone around her size, but Giroro...

She had fantasized a lot, and although she had a very health sexual education and knowledge, she hadn't put much creativity into the size difference.

Giroro seemed a bit hurt by the comment that she hadn't thought about him before.

"I meant legitimately! I wasn't very creative about it in my fantasies!" she tried to reassure him. "You know, just your average boring penis-goes-in-vagina thing."

Giroro frowned and shook his head. "Everyone knows that sex is more than that." His hand drifted to Natsumi's breast as he began to fondle it. Their arguing wasn't particularly sexy, at least it probably wasn't to her.

But to him, arguing with Natsumi was always sexy. But that was a problem he'd probably have to work on. She was no longer his enemy, but his lover.

Natsumi moaned again, letting Giroro trail kisses along her shoulder blade and neck as he played with her breasts. They seemed to interest him quite a lot.

She held onto his butt, still wanting to make this enjoyable for him. "I... I guess I thought about you maybe a few times... You know, before this whole apocalypse thing happened. It wasn't very detailed or creative, just your average masturbation fantasy..." Natsumi admitted between moans.

"Oh?" Giroro felt incredibly aroused by that knowledge. Natsumi was so blunt, not an ounce of shyness in her, unlike him. "Wh-what was I doing?" he asked.

"Well, your face was between my legs..." she began. Giroro grinned, and started tugging her shorts and panties down.

"Got it. I will do as you wish," he grinned, and hungrily looked down at his sweet warrior princess.

Natsumi spread her legs wider apart after kicking off her clothing. She could feel herself warm and incredibly wet from anticipation.

Giroro slowly brought his face down, unsure really of what to do. Natsumi grinded her pelvis against him as if to signal him to hurry up.

Giroro rubbed her inner thighs and put his tongue against her opening, laying it flat. He licked upward, inciting a loud moan from Natsumi.

"Good..." she moaned, putting her hand on the back of Giroro's head. She placed her other hand down toward her clitoris and started rubbing it, to give Giroro a clue that she wanted him there, too. She wasn't going to waste time by asking, though.

Giroro kept licking, drinking her up and eating her out, looking up at her every so often to see how incredibly hot she was being. His hand eventually drifted up to her clitoris and swatted her hand out of the way to work away at rubbing it.

Natsumi continuously rocked herself against Giroro's mouth, sometimes grinding against him to get him closer and closer. She would tell him if he was doing well or where to give her more.

She moaned his name when she orgasmed, rocking against him desperately.

After licking her a few more times, he took her mouth off of her. He looked up at her sweetly, happy he could have such a moment with her.

"You're not getting off that easily," she smiled, rolling to her side to give him a full view of her body. "We're not done yet, Giroro."

"Do you want more?" Giroro asked. He would give her anything she asked for.

"Yep. You're not done making love to me yet." She helped him out of his belt, grinning as she saw his very hard erection. She made a point to ogle it in front of him for a few moments, which caused him to become very embarrassed.

"Is... Is it okay?" He was honestly worried it was too small.

"It looks fine. I like it." She ran her finger along the underside, and Giroro let out a low moan. "Lay down," she ordered, pushing him onto the ground.

"Huh?" He was on his back, faster then he could fight back, and Natsumi was standing over him. She probably intended to ride him.

He blushed. Sure, he had fantasies about Natsumi on top but as the macho guy he was, he had always assumed he'd be the one leading the situation. But no, reality was much different and Natsumi was way more experienced and mature about this, it seemed.

She took a hold of his penis at the base, and led him into her. "Don't move that much until I'm comfortable," she ordered sternly.

He nodded and then froze, trying not to move. He was completely embarrassed and it was very hard to focus on anything except the amazing feeling of being inside Natsumi.

Eventually, Natsumi started slowly moving, experimenting herself with tiny movements up and down.

"Sh-should I move yet?" Giroro asked. It was hard to just not let his eyes roll back and moan. Natsumi laughed a little bit.

"Yeah, you can move. But take it slow at first. I don't want you ramming into me, to start out. Mom said that's not very fun. You feel great, but I need to adjust." She let him slide part of the way out before going back down at a much quicker pace.

Giroro moaned at every small movement she made. He put his hand on one of her hips, clawing into it to get a good grip. Natsumi smiled and started at a little quicker pace, letting him try to match her.

Luckily, they both had a similar idea as to what speed and rhythm they wanted to go at, so their insides were incredibly compatible. They got a little bit competitive in speed, but Giroro tried to at least get somewhat of an upper hand by rubbing her clitoris again with his fingers, knowing she liked it there.

"Giroro... that feels so good.~ Don't stop. Keep going..." she would moan out. He tried to bring his torso a little bit upward in a sitting position so he could kiss her chest and underside of her breasts. She was a sweating mess, moaning and telling Giroro how good he was.

It didn't take long at all for Giroro to reach his climax. "I... I'm going to cum, Natsumi." He gripped onto her hips harder.

"Good," she smiled, satisfied and let him thrust into her a few more times, before finally squirting into her.

He moaned and wheezed as he finished up, slowly letting her detach herself. She laid down next to him and snuggled for a moment.

"Do you want more?" Giroro asked, kissing her softly on her lips. "I love you, you know."

"I know," Natsumi giggled. "And this is your pretend last night. I expect you to be making love to me for the rest of the night," she told him. "But I'll let you recover for a moment. After all, you're not as tough as me."

Giroro took offense at that. He bolted up. "I am too as strong as a Pekoponian!" He'd prove her wrong. Exactly like she had wanted.

He grinned as a spark of rivalry went between them.

It took them an incredibly long time for them to finally give in and give up from exhaustion. That was a lot of sex that they both had experienced.

Natsumi wrapped her arms around Giroro and kissed him on the cheek, snuggling with him under a blanket.

"So you'll be fine tomorrow?" she asked. "And you'll come back soon?"

"I will," he promised. "Just... promise something for me, too, all right?"

"Anything," Natsumi agreed.

"While I'm gone... I know you won't get together with him, but I'm still a little jealous. You won't hook up for Saburo, right? I mean if you want to be with Saburo I'm fine with that but I'd like you to end things with me first... Just wait for me all right?" Giroro begged. Natsumi held his hands and kissed his knuckles.

"I promise to wait. But don't worry, I won't get together with Saburo. I'll wait for you to come back and then this will become our everyday," she promised.

Giroro smiled. "Good. I love you so much, Natsumi," he told her.

"I love you, too," Natsumi told him. And they slept through the rest of the night together, for the first and probably last time.

Natsumi waved him good-bye the next day. They had said their more romantic good-byes on their own. They had decided that nobody else needed to know about their relationship until after Tamama and Angol Mois were back, safe and sound. It would have probably just distracted them on the mission.

"We'll be back soon," Keroro and the platoon promised, dressed in radiation suits. They saluted their human friends.

"You better be, stupid frog. Or I'll beat you up," Natsumi grinned. She had faith that they'd be back. They had all told her they'd be fine, after all. And even if their radiation suits did run out of air, their Keronian bodies would probably protect them.

Keroro laughed and smiled. And the frogs all exited the base.

None of the four humans ever saw them again. It took them a month to realize they weren't coming back.

Natsumi shed many tears.

Please review! Also, sorry, I'm not the best at smut. I just remember last time I wrote a Gironatsu story (A primary M rated one) a lot of people were asking for smut, so I included it this time.
