Sanji looks up, meeting Luffy's gaze and smiling at the way the other man's eyes have already gone half-lidded. With a pleased look on his face, he places a kiss next to Luffy's belly button, bites lightly at the skin in a playful gesture, and then keeps kissing his way down towards his happy trail.

He makes a low, soft hum when his fingers touch his hair, pleased with the gesture and encouraging it further. He likes having his hair touched or yanked, and he is sure Luffy might have figured that out already.

He runs a hand up the teen’s thigh, wrapping his hand around the base of his cock. Sanji's hot tongue runs a wet strip from the base up to the cockhead, teasing the slit with his lips before sucking on the tip.
