He decides to have her give him a blowjob. Always a good start.

Luffy then pulled away from Nojiko, making her whine a bit. "Don't worry, there's more fun to be had," he chuckled, and turned to write, "Nojiko will have an irresistible urge to suck off Monkey D. Luffy, until he cums in her mouth. Upon tasting his seed, she will be hooked on it, as well as the experience of sucking his cock, and will readily agree to anything in order to be allowed to do it again in the future."

He closed the book, and her eyes seemed to glaze for a moment before returning to focus, and she smiled at him, walking over seductively before kneeling and pulling his pants down, releasing his erection. "Sorry, but I'm sucking you off," she told him as she stroked him to full hardness.

"No complaints from me... go for it," he moaned, feeling her soft hand working his shaft. She began to lick his tip eagerly, and then took it into her mouth, moaning sluttily as he put a hand on her head.

She groped his balls as she licked his shaft while it was in her mouth with what limited mobility her tongue had in there. She then began to bob her head, looking up and meeting his eyes as he grinned down at her. She had the cutest little doe eyed expression that held a fake innocence that contrasted with her current actions.

He began to pump his hips as he felt the stimulation running along his shaft. "Oh yeah, keep that up..." he grunted.

She obliged, meeting his thrusts with each bob of her head, before she felt him throb in her mouth. She continued regardless, and he gave a pleasured gasp as he let his seed filled her mouth.

She moaned at the taste and pulled off, swallowing, and shuddering like she had the most delicious treat of her life. She then gazed up at him, lust in her eyes.
