Luffy had spotted the chef across the deck and ducked instinctively. It wasn't breakfast yet for another few hours and he was pretty sure Sanji would kick him back to bed if he spotted him trying to grab a pre-dawn snack. He relaxed a little as he saw he hadn't been discovered and that in fact his position was the perfect hiding place behind the corner railing where the cook had to have a blind spot. He could observe the chef and not be spotted! He glanced over but it quickly turned into a stare.
Sanji was apparently training. His long right leg coming up in a fluid motion and resting his ankle across his neck. Luffy was pretty sure even he couldn't so that with his rubber body. Well, maybe for a second but the tension would probably slam his head back into the deck. Sanji seemed perfectly stable and as he exhaled returned that leg to the ground and repeating the action with the other.
"Trying to sneak a snack?" Zoro questioned as he took up a position next to his captain looking out at the cook. Luffy jumped at the realization he was caught.
"No...sleep walking..." Luffy made a stilted motion and turned around to head back to bed. Zoro grabbed his shirt and looked nervously back toward the bedroom. Luffy was surely going to wake someone up if he went back right?
"Hey hey, I'm not going to tell. Besides...you'll miss the best part."
Luffy sat back down with a curious smile. He was rewarded soon enough.
The cook had carefully removed his shirt and placed it aside, revealing his thin but well toned chest. Sanji bent over slowly, giving the two on lookers a inadvertent show of his very tight ass, letting each vertebrae lower him further, bending only at the hips and letting his head lower beyond his groin.
"Image what he could do even for just himself." Zoro smirked to Luffy who couldn't tear himself away from the sight.
Sanji planted his hands behind his feet and slowly lifted himself into an elegant handstand, then letting the legs sway over letting him land in tight back bend. After a moment the chef let himself collapse on the deck, contented smile and legs apart, panting lightly at the slight exertion and a redness creeping into his cheeks.
Zoro made a noise and Luffy looked up to see the swordsman trying to drink in the sight with all his being as a hand trailed down underneath the harameki before quickly realizing he wasn't alone.
"You know, the rest is just boring kicks and stuff he does all the time."
"Guess I'll go get my snack then..."
Zoro nodded briskly as he tried to keep an eye on the cook and hurry his captain along.
"Don't worry Zoro, I'm not going to tell!"
Zoro only nodded. He could deny it later anyway. He was just an early riser and sleep was something you could get on the deck later. That this you could only get now, was something he normally kept to himself.
