Dare to be Great Ice Cream Challenge! Eat all 21 scoops of ice cream within one hour, and it’s free!
“21 scoops? That’s insane!” Izuku exclaims, in the middle of talking Katsuki’s ear off about his day on patrol over dinner. “Can you believe people have actually eaten that much in one sitting-” Katsuki scoffs loudly, smirking. “What?”
“As though I haven’t seen you work your way through gallon tubs of Bluebell after a bad day, binge-watching sad movies? I bet you could knock out that sugary mess no problem.” Deku pouts, a look that Katsuki can never get enough of. That lovely bottom lip sticking out was more than enough reason for him to tease his boyfriend mercilessly, and goodness was it easy to get a reaction. “Y’know what? Let’s go there tomorrow. We both have an evening off after all.”
Izuku quickly lights back up into an excited grin. “That sounds great!” he exclaims, and starts blabbering about the restaurant’s menu, and options on where and when they should meet up, and Katsuki’s already stopped listening, focusing instead on watching Izuku’s expressive face and hands.
The pair decide to do an intense workout at the gym to work up an appetite before walking over to the restaurant together. Izuku is practically salivating in excitement, while Katsuki just hopes this place has some decent real food.
They are able to get a nice cozy booth by the window, and their waiter is a burly fellow kind face. “Now what can I get started for you two gentlemen today?”
“One ice cream challenge, please!” Izuku says, almost jumping up and down in his seat.
“Hahaha, nice choice young man! Now we have the one listed on the sign outside, but if you’re interested, there’s also a couple’s version of the challenge with 38 scoops instead of 42 - in commemoration of our 38th flavor we added last March! Same time limit, no quirks allowed on either, but for the couple’s version you can only use one spoon. So how about it?”
“One… spoon?” Izuku’s eyes go straight to Katsuki, silently pleading for him to agree to it.
Katsuki looks over and sees the watery-eyed stare, and draws it out for a few long seconds before saying, “Alright, fine, have it your way. One couple’s ice cream challenge,” he says, blushing and looking resolutely out the window.
“Thanks, Kacchan!” Izuku leans over the table and gives Katsuki a quick peck on the cheek. “Oh! And hot cocoa to drink!”
“Make it coffee for me. Black like the pits of hell,” Katsuki grumbles out. “Too damn sweet…” He leans his head back and slouches down into the booth, mentally preparing himself for all the extra workouts he’ll need to do to make up for the literal wheelbarrow-full of ice cream he’s about to ingest. “Alright Deku, if we’re gonna do this ridiculous thing, let’s split up the flavors. I’m not about to go eating some bullshit flavor like ‘sweet cream’ or ‘pistachio.’”
Izuku laughs merrily. “Of course, I’ll take any flavors you don’t want Kacchan. As long as I get some of the triple chocolate and strawberry!” They go through the list, Katsuki agreeing to take all 4 different matcha flavors offered (“Why on earth would you ever need more than one regular matcha flavor?!”) and Izuku taking the majority of the chocolate-based flavors (“Molten chocolate, Triple chocolate, Fudge - what’s the difference?” “Kacchan, clearly you are not the chocolate expert here. Let me take those.”) when suddenly their waiter arrives, carrying what looks like a fancy catering-size dish full of ice cream with the help of another waitress.
The ginormous sundae is hefted onto the table, and the waiter, panting, pulls out a large spoon with hearts and a bow along the handle. “Once I give you this spoon, your hour begins. Ready, and - go!”
Izuku takes the spoon first and digs into the nearest chocolate flavor. “Mmm!!” he brings his hand up to his cheek, savoring the taste.
Katsuki grumbles. “We don’t have time for you to waste tasting the stuff!” He snatches the spoon from Izuku’s hand, and starts shovelling in some of the rocky road flavor.
“Hey wait! I wanted some of that one!” Izuku takes the spoon back with the last bit of the rocky road scoop left on it, and eats it, giving Katsuki a hurt look that breaks into a smile again quickly. “It’s hard to be mad while eating ice cream!” he giggles.
From then on, they alternate, switching spoons after eating one entire scoop of ice cream. Katsuki, eager to get this over with, gets brain freeze more than once trying to eat it too quickly - luckily the coffee is there to warm him back up. 50 minutes go by, spoon moving slower, and now only two scoops are left.
“I told you I wasn’t eating no pistachio - who decided that should be a popular flavor, huh?”
“B-but I’m supposed to take the chocolate ones -”
Katsuki takes a small bite of the deep brown ice cream. “It’s dark chocolate. You still want it that badly?”
Izuku sighs. “I guessss you can have it, I’ll eat the pistachio….” He gestures to Katsuki to give him the spoon, but his boyfriend has other ideas.
“Maybe it’ll taste better if we mix it. I mean, these are getting pretty melty now…” Katsuki mixes a small spoonful and tries it. “Nope. That’s quite possibly the worst thing I’ve ever tasted in my life. Thanks, Deku.”
Izuku is almost comatose from the sugar overload, and doesn’t react apart from grabbing the spoon and staring at it, thinking about the numerous indirect kisses they’ve been sharing through it.
“Time’s ticking, Deku. Hurry it up over there, or we’re gonna have to pay for this monstrosity.”
That snapped him out of it. Izuku focuses back on the plate and shoves a large spoonful of pistachio in his mouth. “Hey, it’s not that bad …” he says around his mouthful of sugar, and proceeds to finish it off. “Last one for you!”
There are five minutes left, and Katsuki spends 2 of those minutes continuously drinking coffee before demolishing the last of the ice cream. The two of them are utterly crashed out and barely conscious as the waiter congratulates them and announces to the rest of the diner the feat they accomplished. “Alright folks, let’s get your picture taken for the wall!”
“Wall? Oh no, we look a mess, don’t we?” Izuku says, stretching out his arms.
“No no no, you’re fine! We must capture the moments following your victory!”
“Deku, you’ve got a little something on your-”
“Say ice cream!” click. The camera flashes right as Katsuki dives in to lick some chocolate off of Izuku’s cheek. “Well, that one’s definitely going on the wall. Thanks, guys! Have a good night!”
They ride a cab home, too stuffed to walk to the bus station. When they get into the car, Izuku whispers to Katsuki, grinning from ear to ear, “Thank you, Kacchan,” and kisses him.
The kiss is returned sloppily but with fervor, and the two lazily make out the entire way home.
Katsuki decides that the pistachio flavor is okay, as long as it’s in Deku’s mouth.
