Gundam 00 Fanfic
So, I finally watched all of Gundam 00. And this is where it leads me. Totally random, but it's a Nena/Setsuna crack fic. And it's a bit on the naughty side. I have no idea where it came from... XD

---

How on earth did I get myself into this? Setsuna wondered, groaning inwardly as he walked up to the room. On the outside, he looked as unreadable and calm as ever, but on the inside, he felt a growing sense of anxiety.

Who knew that his one and only hobby would land him into this kind of trouble? Violent combat, he could handle without fear. Staring down someone holding him at gunpoint, no problem.

 

This, however, was terrifying…

 

“Aren’t you going to carry me over the threshold like a proper groom, Setsuna?” Nena cooed, poking her head out from around the corner and winking at him.

 

“…”

 

“Come on, don’t be grumpy. You should be happy that Nena is your lovely wife~” she added, making her way over to him, her frilly pink gown rustling around her. It was an odd choice for a wedding dress, perhaps, but Nena liked pink better than white, and the single question she had received had resulted in a glare scary enough to silence any other comments.

 

“…” Setsuna stared at Nena blankly. She knew as well as he did that he had been blackmailed into this position. Why was she acting like this should be the happiest day of his life?

 

Rather than waiting for Setsuna to actually say something—what were the odds of that when he was giving her that look?—Nena took it upon herself to hop onto Setsuna, wrapping her arms around him and giving a delighted squeak when Setsuna’s arms snapped out to catch her and one hand landed on her posterior.

 

“Naughty, naughty~” she giggled, pinching Setsuna’s cheek before nuzzling against him. He made a slightly choked sound and adjusted his grip, feeling his cheeks heat up a little. First she stole his first kiss, and now hers was the first female posterior he groped. What was next, his virginity? That hadn’t been part of the deal. That wasn’t for Nena.

 

“Where are we going?” Setsuna asked, just staring at her.

 

“Into your room, silly~ I made a few adjustments so it would be just perfect for our wedding night~” One could practically hear the mental hearts that had to be escaping Nena as she spoke. Setsuna had a sinking feeling.

 

“You shouldn’t have done that,” he muttered.

 

“Why not~?” Nena asked, gazing up at him curiously as he carried her along.

 

“You know why I married you. It’s nothing to celebrate.”

 

“Of course it is~!” Nena replied, leaning up to kiss him now.

 

Setsuna sputtered and choked, nearly dropping Nena in surprise before he managed to yank his head back. Unfortunately, he also ended up bumping Nena’s head on the doorframe as they passed through it to enter his room.

 

“Ow…! What was that for?” Nena asked, pouting as she reached up to rub the bump on her head.

 

“Your fault. I didn’t say that you could do that,” Setsuna replied tersely.

 

“You don’t have to say that I can do that now, dummy,” Nena replied, narrowing her eyes a little. “We’re married now. So I can kiss you whenever I like~” she sang, her features once again growing cheerful.

 

“No.”

 

“What do you mean, ‘no’?”

 

“I mean no. Your terms were that I marry you, and I did that. That is all I agreed to do.”

 

“… But we’re married now,” Nena protested, wriggling out of Setsuna’s arm now to land on the bed once they were close enough. “So, you can have your wicked way with Nena~ Quit playing coy. Miha-nii isn’t around anywhere, so you don’t have to worry about him stabbing you or anything~”

 

“No.”

 

“No…?” Nena asked, her features darkening in ominous fashion.

 

“No.” Setsuna might have given in to her blackmail about the marriage, but that was as far as it was going. His virginity was for Gundam alone. Like all of the rest of him. Even kissing Nena was really like cheating on Gundam.

 

“We’ll see about that,” Nena replied, putting on a coy smile. “Will you at least eat a little wedding cake with Nena? It would be so mean to refuse…”

 

“Fine.” If it would get her to leave him alone, then Setsuna supposed that he could eat a little cake.

 

“Open wide~~~” Nena cooed, picking up the slice of cake that she’d had waiting and offering a forkful to Setsuna. She had known that Setsuna was probably going to be difficult, but that was what the cake was for. There was enough of a drug in the cake to dull his reaction time after only a few bites. Thus, as soon as she had given Setsuna a few forkfuls, everything was in place.

 

Nena put down the piece of cake and subtly reached under the table, drawing out the pair of handcuffs she’d put there earlier. Without any warning, she snapped one out and caught Setsuna’s wrist, dragging him back forcefully towards the bed.

 

Setsuna exhaled sharply, feeling the room spin a little. “Wha… what’re you doing…?” he mumbled, staggering over to the bed and falling back on it when Nena pulled him against it. In a matter of seconds, his hands were cuffed to the headboard. It was only as Nena began to undress him that Setsuna began to grasp what was going on.

 

“Let me go… I refuse this,” Setsuna said, managing to focus on her face after a moment. His shirt was already open. This was bad. Without warning, he kicked up one of his legs, hitting Nena in the stomach as she tugged off his shoes.

 

“Oof…! Setsuna, what the hell are you doing?!” Nena exclaimed, jumping back out of range of his legs. “That hurt… You’re so mean to Nena.”

 

“I said that I refuse this and you didn’t listen.”

 

“Hmph. We’ll see about that!” Nena replied, drawing back and beginning to undress seductively before his eyes. As the dress slipped off the curves of her body, it revealed just how well-formed Nena’s figure was, the pink lingerie she wore hugging every inch of her.

 

Setsuna swallowed thickly, wondering why he couldn’t stop staring at her all of a sudden. It had to be whatever drug she’d given him. Otherwise, he wouldn’t be noticing what a nice ass she had… or how she was almost as pretty as a Gundam…

 

“You like what you seeeeee?” Nena asked, reaching for Setsuna’s pants now and yanking them down forcefully, so that the button popped off and they eventually gave way. “It’s all for you, Setsuna~” she purred, climbing atop him now that they were both undressed down to their underwear.

 

“I should make you pay… for doing something like this to me… Nena Trinity…” Setsuna mumbled, finding himself growing increasingly distracted by her proximity now.

 

“Nuh uh… It’s Nena F. Seiei now… just like you~”

 

“Nena Trinity…” Setsuna replied stubbornly, staring up at her wide-eyed as she leaned closer. He didn’t even know what point he was trying to prove in arguing that, but controlling that was a lot easier than trying to control the way his body seemed to be reacting to her.

 

“Nena F. Seiei. You can’t say it’s not, because we’re married now!”

 

“Only because you blackmailed me.”

 

“Only because you look at Gundam porn. Not even Miha-nii is that depraved,” Nena replied teasingly, leaning closer still. “It’s quite deviant to like Gundams that much, you know…”

 

“Do not make fun of Gundam,” Setsuna replied, struggling against the handcuffs now as he began to get agitated. He managed to yank one hand down enough to grab at Nena’s neck, and he gave her an angry look as he pulled her closer.

 

“Then find something better to like,” Nena replied, plunging forward to kiss him. At first, Setsuna tensed and made a sound of agitation. Then, he was suddenly kissing her back, all of that agitation and annoyance getting mixed with the lust he was feeling. Anger and passion aren’t so far apart after all… Setsuna thought as he dazedly gave in to Nena.

“We just heard—”

 

“Did you really—”

 

“What the—”

 

“What is he doing with our sister?! I’ll stab that bastard!”

 

“Michael, calm down. That’s not an appropriate reaction.”

 

“Did Setsuna actually…?”

 

“With Nena…?!”

 

“I guess it would be pretty cruel to wake him just now…”

 

“Too late.”

 

“…”

 

It was only then, when faced with discovery by the collective members of Celestial Being, that Setsuna discovered that there was something much more embarrassing than being found out to have a Gundam porn fetish. Being caught in bed with Nena Trinity was definitely much, much worse. Especially when Michael was wearing that psychotic expression again… It was hard to defend oneself when one was in a state like this. At least he would be hard to stab with Nena still asleep on top of him…
