Sideswipe scrunched his faceplates, puffed up his cheeks, and smashed the palms of his hands into his cheeks, sticking out his glossa. Sunstreaker stared at him strangely, "Sides…what are you doing?"
"Twiying o shee how wany fwaces I could wake." Sides said against his muffled face.
"….What?"Sunny asked dumbfounded.
Sides sighed, letting his hands go down from his face and smoothing his helm down as if he was smacking himself in the head. His bright blue optics was wide with childlike joy, which Sunstreaker couldn't help but find adorable on his brothers faceplates. His mouth plates were stretched in a big smile and it looked as if his faceplates might crack. His bright red paintjob gleamed brightly.
"I said," Sideswipe stressed, "I was trying to see how many faces I could make." He proceeded to stick out his glossa and, Sunstreaker didn't even know how it was possible, crossed his optics together
Sunstreaker bit his mouth plate, a human habit, to stop laughing, "And why are you doing this?"
"I was bored," Sideswipe said shrugging.
Sunstreaker grinned, "So do you want to do something interesting?"
Sideswipe pursed his lips in mock concentration, "Sure, I don't have anything better to do."
Smirking, Sunstreaker reached and grabbed a bucket of paint Sideswipe was going to use to prank Wheeljack and held it secretly behind his back.
"So...any ideas?" He smirked
Sideswipe shrugged again, "Don't know, you mentioned it."
Sunstreaker smiled slyly to himself and began to creep the bucket of paint closer to the oblivious Sideswipe. "So you're willing to do anything?"
"Pretty much," Sideswipe said casually
Sunstreaker smirked, "You asked for it."
Sideswipe stared, "What?" He looked confusedly at his unusually playful brother.
Sunstreaker continued to smile at him evilly, and drenched his brother with the pain.
Sideswipe shrieked, his vocalizer reaching decibels he didn't know he could reach. Sunstreaker burst out laughing at the indignant look on Sideswipe's face and the squawk of surprise as the paint rained down on him. He gaped at his now pink paintjob and half-heartedly glared at his brother.
"Sunny!" Sideswipe protested.
Sunstreaker burst out laughing, "Well, you said that you wanted to do anything."
Sideswipe groaned, "You know that's not what I meant!"
Sunstreaker grinned cheekily, "And you know only Arcee can pull off the 'pink look'."
Sideswipe growled dangerously.
Sunstreaker just snorted.
