"Y-YOU FUHUHUCKING JEHEHERK!!" Chuuya cackled like a maniac, throwing his head back into the old couch while arching his spine. Squirming and thrashing around were proved useless a long ago, but he simply couldn't help it — his body was moving on its own, his nerves screaming for a way out of this hellish situation he found himself in. "RELEHEHEASE ME NOHOHOW!!"
"You did it wrong, idiot," Dazai scolded, his tone soft yet poised with a second-hand mockery. He shook his head, moving one hand away from Chuuya's body and holding a finger out while he proceeded with the explanation. "It's a really simply trick, even a dumb dog like you can learn it."
"I-I'm nohohot a dohoh- aHAHA, SHIHIHIT! GEHEHET OUT OF THEHERE!!" He screamed, feeling his cheeks burn and some strands of hair sticking to his dampened forehead. Dazai's hands refused to leave his stupidly ticklish armpit, torturing each and every nerve until it they were nearly dull — just to then move a little higher or lower, starting it over.
"The book I read said patience and repetition are keys to taming dogs," he continued and Chuuya widened his eyes in panic as he saw the other hand coming back to 'work'. "Of course, a little reprehension is also necessary to correct… unwished behaviors."
Oh, how much he wished he could snap Dazai's neck in two right now. Chuuya pulled at his arms, both trapped under Dazai's knee, and planted his heels into the soft cushions, screaming insults as hard as he could through his angry laughter. Dazai only hummed along, keeping himself comfortably sat right next to his 'dog's' face, admiring his hysteric reactions.
Still, it felt like a rock was holding him down. He felt his hands going a little numb, his blood barely making to the tips of his fingers under all that jerk's weight. His pride was repeatedly telling himself to not submit, to not fall for Dazai's antics again — but it tickled so, so bad!
"F-FUHUCK!!" Chuuya shouted again, gasping as those words took the last bits of air he had inside his lungs. "F-FIHIHINE, YOU— AHAhahasshohole! AHah, w-wohohoof! WOHOHOFF!"
"Hm, what was that?" Dazai grinned, leaning his head a bit closer just to look down at Chuuya's desperate smile from the right angle. "Did you say something, mr. Doggy?"
"YOU PIHIHIECE OF- AHAHAH!" Chuuya widened his eyes, not expecting the tickling to get even worse than it already was. "I— AHAHA, WOOF! WOHOHOF, PLEHEHEASE!"
"Good boy! ~" Dazai purred and freezed his hands on spot, leaving his fingers curled, but still, against Chuuya's body. He watched the redhead's chest wave, his ragged and hoarse breath stopping the silence from taking over the place. "See? I knew even you could learn a new trick."
"G-go— hahh, t-to hell!" Chuuya whined, feeling his head spin. He had been tickled before, sure enough, but Dazai was simply a beast. He couldn't even figure out what that freaky bastard was doing to make him laugh like that. It didn't matter, thought, what matter was that it was ov—
"Oh," Dazai smiled, pressing his knee a little harder against Chuuya's hands again, as if changing his mind about letting him go. "I remember that the book said to praise and give treats to your dog while taming it, too. Supposedly, it helps them memorize the trick."
"D-Dazai, don't you f-fucking dare!"
"Now, who is a good doggy? ~"
"You piece of shiHIHI- AHAHAA!"
