Supertasters are real! Google it! (Or at least listen to the They Might Be Giants song.) 30 Kisses theme #18: "say ahh...."
"Yuuta, if you don't stop wiggling, I'm going to have to hold you down."
"I hot igga ing!" Yuuta protested.
Syuusuke, ignoring his younger brother, grabbed the end of Yuuta's tongue between his thumb and forefinger. "That's better."
"AHIKI!!"
"Now let's see...." Syuusuke squinted at Yuuta through the magnifying glass. Yuuta tried to hold still, but it seemed harder with his brother holding onto his tongue. Aniki's fingers felt very hot.
"Thirty-six," Syuusuke finally announced. "Congratulations, Yuuta; you're a supertaster."
Yuuta tried to retrieve his tongue, but the bottom had stuck to Syuusuke's thumb, a fact that didn't seem to bother the other Fuji very much. He pulled it free with an ungraceful yank. "Ow." He peeled a small piece of paper with a circle cut out of the middle from his tongue. "Great. I'll remember that the next time you make fun of me for putting five sugar cubes in my tea."
"The five you put in at first, or the five more you put in when you think no one's looking?"
"Shut up."
"Okay, do me now." Syuusuke cheerfully stuck out his tongue, which, like Yuuta's, was dyed blue with food coloring. He took the piece of paper that had been on Yuuta's tongue and placed it on his own. Yuuta thought that seemed kind of unhygienic, even if they were brothers.
Yuuta leaned over cautiously, as if he didn't want to get too close in case Syuusuke suddenly decided to lick him. The weirdo was always doing stuff like that. He peered at the pink bumps rising from the blue circle of his brother's tongue.
"You have like five."
"Hm, I guess that makes me a non-taster," Syuusuke said, checking the magazine on the kitchen counter next to them.
"'Supertasters tend to prefer sweet foods, while non-tasters often prefer bitter and spicy foods,'" Yuuta read aloud. "Hmph. I always thought you were weird in the head to eat that stuff, but I guess if it's a physical deformity, there's not much you can do about it."
"Ha, ha. That's the spirit." Syuusuke smiled and patted Yuuta on the head. Yuuta bristled and reached for a washcloth to wipe the food coloring off of his tongue. "Although," Syuusuke said from behind him, "if you're that worried about my lack of taste buds...."
"Huh?"
Before Yuuta could even finish turning around, Aniki's hands had grabbed his wrists and Aniki's blue tongue was in Yuuta's mouth.
It seemed to take Yuuta's brain several tries to get his body to move, so that when the signal finally got through, he ended up flailing his arms in several unhelpful directions and backing into the counter so fast that he knocked a frying pan to the floor.
"What the hell did you do that for?!" he shouted.
"I thought you'd want to share," Syuusuke replied, smiling and tilting his head to the exact angle known to annoy Yuuta the most.
"You stupid brother!! You are weird in the head! I'm never coming home again!"
Yuuta stomped upstairs to his room and spent the next three hours and fourteen minutes blowing things up on his Playstation and trying not to think about how Aniki's tongue tasted.
