His rationale made no sense, but it was just Naruto looking for a flimsy excuse to give into her lowest urges. Robin argued, but only out of obligation. She knew that she had places she needed to be, Doflamingo was their target. Instead, she found herself passive as Naruto climbed on top of her. She was lying in a prone position with her chin resting on the dirt and her arms trapped under her. She felt his hard cock between her buttocks, searching for entry. Robin knew Naruto would have no trouble finding it. The head pushed into her asshole and eased in. The Archaeologist gasped as her backdoor was stretched by the girth of his cock. Naruto gripped his crewmate's hips firmly as he started to pump his hips. He grit his teeth as he penetrated her deep with his long cock. "Oh fuck, Naruto," Robin moaned, her eyes fluttered, "So deep..." "Quiet, they'll hear you," Naruto said, he reached around and put a hand over her mouth. Robin didn't think it mattered, the Tottoland people were all around them in the trees, it would be naive to think that not one of them was peeping on them. It was more realistic that every single one was watching them in some way. Robin didn't mind, it kind of excited her to have an audience. Naruto quickly abandoned the hand over her mouth, he switched to a grip on her long, black hair. He yanked her head back, pulling hard. Robin smiled, she liked it when they got rough with her. The ninja's hips thumped against the Archaeologist's ass, the impact sent shockwaves through her skin. Her plump ass rippled with each stroke of his hips. Robin was so turned on, she desperately wished she could sneak a hand under herself and rub her clit. It would be so easy to bring herself to orgasm, but her arms were trapped securely under her chest by the threads. Smack. Smack. Smack. Naruto's alleged fears of being heard were not enough to prevent him from clapping her asscheeks. He pounded her ass with reckless abandon, he had forgotten everything aside from the pleasurable sensation he felt from fucking his friend. Robin could tell he was close. He grit his teeth and squeezed her hips with both hands so hard that it started to hurt her. Robin didn't mind that though, the pain was also a turn-on. "Oh god, don't stop!" Robin growled between clenched teeth, "Give me that fucking load, right in my ass! Ugh!" The trapped woman felt the warm sensation of cum flooding her ass. It rendered her speechless as Naruto shot more and more seed into her backdoor. Naruto needed a moment to catch his breath, his cock remained inside of her until he was ready to move on. He eventually pulled out of her, Robin moaned as his cock left her anus. Once he was dressed, the future Hokage called on his devout clones to free his sidekick and they continued with their mission. Robin followed behind, she wished she had a moment to sneak away and release some tension. That would have to wait though, there were more important matters at hand. Surely though, during the fight that was yet to come, someone would rather fuck her than fight her...
