She decides on being a during sex, but assertive at all other times!

Marguerite thought hard, without any of her inhibitions around to muddle her thoughts regarding what she desired. "Um... I think... I'm very submissive myself..." she blushed. "But... I don't want to be... treated like I'm lesser at any other time... Like... being dominated during hot times is hot... but I don't want to be seen as less capable when we're not doing such things..."

"...why would I think that?" Luffy asked her.

"Master, some people think that the fact that they like being on the bottom during sex makes them something of a weak little bitch," Hancock explained with an amused smile. "And even if they don't think of themselves that way, there are stereotypes about submissives, and they often worry about what one would think..."

"...well, that makes no sense... what turns you on, turns you on, right? Even I understand that much, even if it's because of that wish I made before..." he remarked.

Marguerite stared at him. "...Empress, you managed to make him so perverted, and so innocent at the same time..." she remarked, genuinely amazed.

"It's a gift, comes with being a Sex Genie, I can do things with an absolutely perfect touch," Hancock grinned. "... does that put your worries to rest?" she asked Marguerite.

Marguerite nodded, and smiled. "Yes... in that case... please make me totally obedient to you during sex... Master..." she begged Luffy.

Luffy nodded eagerly, turned on by the prospect. "Hancock, I wish whenever Marguerite and I were in a sexual situation together, she wouldn't be able to resist my commands, and would feel intense pleasure just from doing what I told her to do..."

"Done!" Hancock grinned, snapping her fingers immediately. Marguerite gasped, and moaned, blushing as the spell took hold of her. She was aroused by it already.
