Hands came to clutch at his haramaki as Sanji returned the kiss. It was reminiscent of the first time they'd done this, after the encounter with Kuma on Thriller Bark. The cook had looked wrecked finding him after, and it'd taken days before Zoro remembered Franky's advice to him. The difference now laid in experience. Zoro knew Sanji's body, and the opposite also held true. He wriggled into a more comfortable position, and encouraged Sanji's questing hands with a suck on his tongue. When they roamed down his back, Zoro's legs widened of their own accord. Fingers dug into his firm asscheeks, kneading and spreading them. Then they pressed into his crease, and Sanji's breath stuttered, breaking away from the kiss. Then the cook groaned, a dirty, incorrigible sound. There's a number of responsibilities Zoro has as first mate of the Straw Hat Pirates, and sometimes that includes fighting the demons of a certain curly brows... naked.
