Has her blow him while he makes her a .

"That was fun," she panted, still holding onto Luffy.

"Yeah... I got an idea though... How about you duck under the water and suck me off?" Luffy suggested.

"Um... Sure, okay!" she said, still riding off the high of being fucked, and she quickly dipped under the water. Luffy felt her wrap her lips around his shaft as she held his hips, working her tail to help keep herself pressing against him as she sucked away.

Luffy then turned his head towards his clothes, and stretched out an arm to grab the Sex Note from them. Gotta love Devil Fruits. Making sure to grab the pen as well, he pulled both items to him, and opened the Sex Note.

"Camie will gain the mark of the Straw Hats Pirates on the small of her back while she sucks off Monkey D. Luffy. The mark will come in gradually, and have a pleasant feel to it as it does, and while Camie will notice, will not stop sucking off Luffy until he cums. When he does, the mark will finish forming, and she will become his sex ****. Outside of this, she will retain all her personality traits and her friendship with Luffy."

He then returned the Note and pen to where he had gotten them from just as he felt Camie stiffen momentarily, but quickly returned to sucking him off. She was fondling his balls as she worked, and he reached into the water to pet her head.

A few bubbles came up, no doubt due to her letting out a moan as she kept bobbing her head on his shaft. She pulled off momentarily to start licking at it, before putting it back in her mouth as he started pumping his hips, seeing the mark form beneath the water, nearing completion as he approached his release.

He finally came, and moaned out as his seed filled Camie's mouth. She gulped his seed down, shuddering as the mark finished forming. She then lifted her head from the water with a slowly growing and sultry smile. "Did you enjoy that... Master?" she cooed.

"Sure did," he grinned.
