Yes, get a blowjob.

Luffy got up with Kaya also standing, smiling at him a bit. He then gave his fingers yet another snap, and she blinked. Then she fell to her knees, and grabbed the waistband of his shorts. "Uh, Kaya what are you doing this time?" Luffy asked, though by the grin on his face, he knew exactly what she was doing.

"Just... I just need to suck your cock," she blushed. "Is it alright if I do so?"

Luffy nodded, giving Kaya a grin. Kaya smiled, albeit still red in the face, and proceeded to pull open his shorts, then pull them down with his underwear. His cock sprang free, and she froze up, biting her lower lip while blushing furiously. It was quite adorable to see, and Luffy waited patiently for her to get started.

Eventually, she regained herself, and leaned forward, licking at the tip of his erection, and moaned as she gradually got more into it, licking along his length, before nestling his cock with her tongue, and moving her head forward to engulf his shaft, taking it all the way to the base. Her eyes were closed for a moment, before she began to move her head up and down his shaft.

Luffy moaned in pleasure as he watched her repeatedly devour his shaft, putting a hand in her hair as he gently aided her head motions. She opened her eyes and looked up at him as she continued to bob her head, her mouth sucking away at his shaft. "That's it, keep going, you're making me feel great," he encouraged her, and she complied, beginning to fondle his balls with one hand, steadying herself with her other hand on his thigh.

They kept this up for a few minutes, before Kaya felt Luffy's cock throbbing in her mouth. She quickly pulled off until only the swollen head was left wrapped in her lips, so when it spurted out his seed, it splashed against her tongue, and the insides of her mouth, filling it up. She moaned at the taste, and gulped it down eagerly.

Luffy smirked as he pulled out of her lips with an audible pop, leaving her panting, her tongue hanging out as if to show him she swallowed it all.

"We should head back now," he grinned at her as she caught her breath.

"Yeah, it's about time to do so," she nodded, getting up, and turning to pick up her clothes, Luffy grinning at the sight of slight black pigmentations on her back.
