He fucks her.

"Boa Hancock will lay back and let Monkey D. Luffy fuck her," Luffy wrote, and she wasted no time in getting on her back and spreading her legs.

Luffy laid over her, grinning like he generally did, and slowly slid into her, making her moan and arch her back. "Oh..." she cooed as he bottomed out. He began to pump his hips into her as she wrapped her legs around him. He reached up and began to grope her boobs as he went, his hips slapping into her.

"This really does feel good," Luffy moaned, quickly starting to pound into her and make her cry out. He soon came, and luckily, she was sensitive enough to manage an orgasm of her own, biting her lip as she cooed.

Luffy then pulled out of her, and took the Note again in consideration.
