I made an obvious blunder with the last prompt, so I decided to re-do it. This is the result. I personally enjoyed writing this one too because I got the use the phrase 'gay necrophilia' without making it sound awkward...or as awkward as it usually sounds.
OP_Fanforall Prompt: "Two of the crew are in love, have been dating for a while etc and recently decided to get hitched. Celebration ensures. Come the big day both are unfortunately detained somehow. Knowing how upset the couple will be two others decide to marry in their name."
Pairings: Sanji/Nami. Brooke/Franky.
And I don't own One Piece.
It was supposed to be a happy day. Sanji and Nami had been waiting for it for quite some time, after all, and everyone was tired of the wedding prep. So when the first island they landed on in months just happened to be full of Marines who just happened to capture Sanji and Nami, well, no one was particularly thrilled, to say the least. Getting them out was one thing; getting them married however...
"What kind of chapel closes at 4 anyway?!" Franky shouted. "And they just happen to be taking the rest of the year off?! Who does that!?"
"It's 3:30 now," Robin stated. "Getting back Cook-san and Nami-chan will take more than 30 minutes."
"We don't all have to go get them." Zoro said. "It's not like we'd be in a real pinch if, say, two of us stayed behind."
"I get what you're saying." Franky smiled and nodded. "Well, Robin's the only girl left, so she can play Nami, but-" he was interrupted by Luffy pushing a handful of popsicle sticks in his face.
"Everyone draws so it's fair. Orange-colored tip plays Nami, blue-colored tip Sanji. Everyone else is on Team Jailbreak."
Franky randomly picked one and was disappointed to see an orange tip. He looked around at everyone else who had drawn before him to find that Brook had picked the blue tip one.
"...I'm not wearing the dress." Franky stated.
Turns out he didn't have to. Due to the fact that this island was quite a distance away from the rest, weird and bizarre marriages were always welcome at the friendly neighborhood chapel despite their extremely awkward hours and massive amounts of vacation time. The priest didn't even bat an eyelash when he was asked to marry what appeared to be a gay necrophilia couple.
"Do you, Nami, take Sanji to be your lawfully wedded husband?" The priest asked.
Franky sighed. "Yeah, I guess I do."
"Do you, Sanji, take Nami to be your lawfully wedded husband?"
"Yohoho! Of course I do!" It was Franky's opinion that Brook was enjoying this far too much.
"Then I now pronounce Nami and Sanji officially married. You may kiss the...cyborg…thing"
Brook leaned in, but Franky put a hand on his chest to stop him. "We don't have to go that far, Skeleton. Just give us the certificate making this official." He said, turning to the priest.
The priest shook his head. "Kiss makes it official."
"But...you just pronounced us..." He sighed. "Fine." Next thing he knew he had a mouth full of skull.
Brook and Franky left the chapel with the official marriage license proclaiming Sanji and Nami in and official state of marriage in every sense of the word. Brook was still laughing.
"Yohohohoho!!"
"You're enjoying this a bit too much." Franky felt the need to comment.
"Yohoho, sorry Franky-san, but surely you also find this situation amusing even a little?"
"No I don't." He sighed. "At least this'll shut up Mrs. I-need-my-perfect-dream-wedding-or-else and Mr. Nami-san-needs-her-dream-wedding-or-else. I don't think the Sunny can handle any more bridezilla freak-outs…from either of them."
"That's good! Always look on the bright side! Although I must admit, I am a bid upset that I didn't get to see you in a dress..." Franky punched him in the arm…hard.
