Part 2! Not sure if I got the characterisations right here, but hopefully it's good enough. Enjoy!
America had been lying on his couch watching some old western films when Australia arrived. He heard the front door bang open and a booming voice yell "Oi! America! You here mate?" America sat up.
"In here, dude!" Australia popped his head around the corner and grinned, red eyes peering over his shoulder. The koala.
"Ah, thought I might've caught you at a bad time. You ready?" America snorted and stood up.
"This'll be a piece of cake!" he declared, leading the way to the kitchen. The two nations stood facing each other across a bench and pulled up chairs. Australia produced a small glass jar from his pocket and placed it between them. The content of the jar was a very dark colour, almost black. It kind of looked like nutella. America quickly fetched some bread and butter, applied the latter to the former and then opened the jar.
He nearly fell out of his chair.
"Dude! This smells terrible! Are you sure it's ever safe to eat?" he exclaimed, holding one gloved hand over his mouth and nose. The koala made some kind of growling noise in his throat and Australia covered his amusement with a cough.
"Just ignore the smell, mate. It's all good. Trust me, you'll love it! I eat it all the time!" he reassured the older nation. America gave him a sceptical look before shrugging, plunging his knife deep into the jar.
"If you say so," he muttered, smearing a huge glob of the nasty-smelling contents over the bread. He didn't notice Australia's shoulders shaking with repressed laughter as he watched America slather the vegemite on. America lifted the sandwich up, shot Australia – who quickly plastered a very innocent look on his face - one last suspicious glance and took a large bite.
If the smell had been bad, the taste was much, much worse. America coughed violently and gagged, dropping the sandwich back onto the plate and clapping a hand over his mouth. Australia almost fell out of his chair roaring with laughter, slamming his fist down on the table. America rushed to the bin, spat out the offending food and skulled a can of coke to dispel the aftertaste.
"Holy shit dude!" he gasped, shaking his head. Australia was still doubled over on the table, his head resting on one arm, laughing and gasping for air at the same time. The koala seemed to be laughing along with him. After a minute, he lifted his head, tears still rolling down his very red cheeks and a large grin adorning his face.
"I'm sorry…mate. But your face…priceless!" And he lost himself in another fit of laughter. Finally, Australia took a deep breath and rubbed his face with his hands. He gave America a cheeky smile.
"So, what'd you think?"
"It tasted like crap!" America exclaimed. "It was like…something you put in your car! Or beer! And why the hell is it so salty?! You say you eat this all the time?" Australia's smile turned absolutely wicked.
"Remember the dare?" It took America a moment, but it quickly dawned on him. Oh god. He had to eat it all. The whole thing. America suddenly paled and felt like he was going to be sick.
"I…" He looked down at the sandwich. Australia chuckled and stood up.
"Here." Australia pushed the plate aside. "I'll make it the right way, mate. You put on way too much." The two nations swapped positions and America watched as Australia grabbed another two pieces of bread, toasted them and applied the butter and vegemite. This time, only a thin layer was used and more butter.
"There! That's better." The young nation straightened and pushed the plate at America. America looked at it like it might bite him.
"What's wrong? Wimping out?"
"Of course not!" America snatched one of the pieces of toast up and stared at it. Slowly, he opened his mouth and took another bite. It…actually wasn't that bad. There was still the saltiness, but it was much less intense than before. Australia watched him was a satisfactory smile playing on his lips.
"So?" America tilted his head to the side slightly and swallowed.
"It's…still odd. But it's not bad," he mused, taking another bite. He still didn't really like it but…a dare was a dare and at least Oz wasn't cruel enough to make him eat the one he made. Speaking of, Australia grabbed the previously abandoned sandwich and ripped a large chunk out of it with his teeth, closing his eyes and sighing.
"Bloody beautiful," he smiled.
