"Idiot-!" The roar only served to bend the crying Sabo over from where he supported his back against, not being able to stand properly from how hard he was laughing.
Who could blame him? Despite the repetitive bantering amongst the brothers, their youngest always seemed to have a knack for catching others off guard like no other.
That's Luffy for you.
With humorous attempts of a cat and mouse chase, Ace eventually managed to land a hard on punch, his roaring only intensifying from the fuming of embarrassment and anger. Luffy looked away rubbing the forming red bump on his head, undeniably failing at stopping the pout forming on his lips, and receiving another bump in the process.
In-between the bickering, the blonde wheezed out a tease of his own, "Ace is red as a tomato, huh, Lu?!" which only got the one in trouble to snort a bit again.
The two erupted in full laughter all together when the oldest did in fact get flushed in the face even more, "I'm going to kill you both!!"
They were awfully unaware as their marine grandfather began pulling up to the bandits' mountains, about to introduce the newest addition to the family and poor Dadan's care.
