Up against a tree!

Luffy looked towards a tree, and pointed at it. "Go lean against that," he ordered, his cock erect again.

Hancock smirked and nodded. "Yes, Master." She strode over to the tree, her hips swaying, and causing her ass to move in a hypnotic manner and draw Luffy's gaze to it. She reached the tree, and leaned forward, placing her hands on it, sticking out her rear, and gazing back at him with a smirk. She wiggled her rear, wanting him to enjoy the view of her body.

Luffy walked up behind her, and pulled down her harem pants. Her folds glistened invitingly, and he lined his shaft up with them. He then slowly thrust into her. "Unh..." he moaned. "Um, I wish that I had the ability to last until you came..." he wheezed.

Hancock moaned and snapped her fingers, causing Luffy to feel a tingle run through his cock. He grabbed her hips, and began thrusting in and out of her pussy. Hancock bit her lip and looked lovingly back towards Luffy. "Oh, by the gods, this is wonderful~!" she panted, pushing her hips back against him.

As he kept fucking her, he leaned over, moving her hair aside to start placing kisses on the back of her neck. "Oh, you're good at this, Master," she crooned.

"You did implant some decent knowledge into my head," he chuckled, giving her neck another kiss, and sliding his hands up her torso to cup her generous boobs through her harem silk. She murmured happily as she wriggled her hips against his.

He continued to thrust into her, letting his implanted sexual instincts guide his movements to hit every sweet spot in her pussy. "Master, I'm cumming!" she cried out, before her pussy spasmed around his shaft. Just as that happened, his cock pulsed, and with a grunt, he came, filling her pussy up with his sperm.

They crumpled to the grass together, breathing heavily. "...okay, I could get used to this..." Luffy noted.

"Oh, me too, Master," Hancock crooned as she placed a kiss right onto his lips, her legs reverting back into her tail form.
