Months after Arlong killed Luffy and claimed the straw hat as a trophy, he discovered Nami had been skimming extra money from her raids to pay off Cocoyasi Village’s debt. Dragged before the entire crew, she was given a choice: watch a random villager die, or have her sister Nojiko taken and used by the fishmen. Desperate, Nami begged for another way. Arlong offered one—she would become his personal slut. As long as she satisfied him, the others would be kept in check, and she could keep collecting until the village was free.
She agreed. Arlong locked a red collar around her throat, one that had eaten a Restrict-Restrict Fruit. Within hours the collar’s power left her dripping and desperate, unable to touch herself no matter how badly she needed relief. By nightfall she was aching, thighs slick, mind clouded with the memory of Arlong's massive cock that she’d once accidentally glimpsed. When she finally entered his bedroom, already soaked and shaking, Arlong was waiting. He ordered her to strip. Then he told her to get on her knees.
