We get Luffy with a libido!

Luffy gasped as Hancock's spell took hold of him. The Empress turned Genie **** had taken the opportunity to not only give Luffy knowledge of sex, but also implant a libido in him. Not only that, but she made sure he turned out sexually dominant. All within the parameters of the unintentional wish of course.

Luffy blinked and stared at Hancock like it was his first time seeing a woman. "...wow..." he said, his eyes roving on her worse than naked form.

"Do you like what you see, Master?" Hancock purred, putting a hand behind her head, jutting out one wispy hip, posing in an alluring manner.

"Yeah," Luffy nodded, noticing an obvious tent in his shorts.

Hancock also noticed, and gave a mischievous grin as she floated closer, her gaze on it. Her eyes then flicked to Luffy's face, and she gazed adoringly at him with the intensity of a completely servile being staring at their Master. It managed to be even more intense than her adoration of him before then. She put her hands on his shoulders as her gaze smoldered into his. "May I kiss you, Master?" she asked, her tone breathy, excited.

To answer her, he reached up and lifted her veil. Given all the permission she needed, she leaned in, and her lips met his, both of them moaning as they kissed each other. It was a clumsy, but passionate act between them.

Letting his new sexual instincts guide him, he wrapped his arms around her, placing one hand on her back between her shoulder blades, and the other, groping her tail where her ass would be. "Mmmnh~!" she moaned happily as she embraced him right back, prolonging their kiss. Once it was broken, she smiled. "Master... May I have permission to pleasure you with my mouth?" she requested.
