First Time For Everything

                                    

                                          
The cook's lit cigarette dropped from his mouth. It snuffed itself out in the dirt below his feet which were rooted firmly in place due to the shock of finding the Straw Hat's swordsman locking lips with the man he just left the bar with. Sanji happened to be walking on the same street where his crewmate chose to stop in for a drink, and it was simply a coincidence that he saw Zoro exiting the tavern—how could he not notice the swordsman's obnoxiously green hair?
It was a relatively boring night for the cook since he spent the past few hours restocking supplies at the market while the log pose was setting. There was an unfortunate lack of pretty ladies for him to flatter because of the island's strange culture which insisted that the women return to their homes before dark. On his way back to the ship, he passed the bar just in time to see a certain green-haired swordsman leaving with one of the villagers.
The two men appeared quite chummy, causing Sanji to pause in curious surprise because it was unusual for Zoro to be so friendly with a stranger in a new place. The cook reasoned that it was possible the swordsman knew the guy from before he joined the crew—either that, or he was simply drunk enough to become friends with anyone who didn't pick a fight with him.
The blond watched for a moment as his crewmate wandered along the street beside the other man until he lost sight of them when they suddenly ducked into a nearby alley. He furrowed his curly eyebrows in slight annoyance—leave it to Zoro to get drunk and disappear with a stranger in the middle of the night when he obviously wouldn't be able to find his way back.
Where the hell was he going anyway?
Sanji shrugged, deciding that he didn't care while simultaneously resolving to follow the Marimo-bastard before he got his ass hopelessly lost and the crew would have to waste time hunting him down before setting sail in the morning. The cook pulled his package of cigarettes out of his coat pocket and lit up before crossing the street and turning down the same alley that he saw the two men entering.
His eyes quickly adjusted to the sudden dimness, and he stopped in his tracks when he witnessed Zoro had pinning the stranger bodily against a brick wall. Sanji's immediate thought was that his crewmate must have been attacked and was about to kick the guy's ass, prompting his second thought that there was no way in hell someone that scrawny could get the jump on the Straw Hat's swordsman. There was a five second delay in which he moved towards them, planning to make fun of the swordsman for letting his guard down, before his brain caught up to what his eyes were actually seeing, and he realized that he wasn't looking at a fight...
Or at least, not a fight between enemies. There was certainly some sort of fight happening, but it looked more like a fight over who could shove their tongue farthest down the other's throat than anything that might warrant his intervention. His cigarette fell into the dirt, and Sanji's thoughts scrambled as he tried to make sense of the scene because it was clear from their positions that Zoro had not been accosted by some sleazy bargoer and was actively participating in the kissing.
"Wha—what the hell are you doing?!" he asked in bewilderment. If his mind hadn't been scrambled, he might've realized that it would be best to quietly turn around and leave them to their business, but his shock had overridden his sense of propriety and caused the question to slip out before he could think it through.       
The two men broke apart, turning to face the interruption with contrasting expressions—Zoro immediately recognized the cook's voice and was visibly startled by his presence, eyes widening in slight panic as he automatically locked gazes with Sanji. The stranger seemed less surprised to be walked in on in a public alleyway and shot the cook a sheepish grin lacking any real embarrassment.
"Shit—sorry about that, man. I swear we were planning to get a room, but we didn't quite make it that far," he told the cook good-naturedly, though he didn't sound particularly sorry. Still, his smile appeared genuine as he turned his attention back to Zoro and gestured for them to keep walking. "Come on, it's not far. Let's get going before we get carried away again," he said coyly.
