Julia was easily brought under his spell in the sense that she seemed plenty happy with his attentions despite her initial disdain. His sister would soon follow. Had Julia been one of his pets he might have punished her for daring to cum without his permission but as it was he considered it a sign of his prowess as he pumped her foxhole full of his cum. After a few spanks he pulled free from her leaving the foxgirl with his cum dripping down her leg. Frilla tried to act tough but she was certainly wet. After a little fighting Yuuki groaned as he slammed into her.<br/><br/>Like the little submissive fox she was her ears moved back and she lewdly panted.<br/><br/>"I could stop," he said "but why should I? A criminal like you deserves to be punished. You don't even deserve my cock."<br/><br/>He spanked her hard, harder than he had Julia for certain, as he held nothing back roughly humping his sister like the bitch in heat she was or soon would be. He had to admit that her high class foxhole was something he enjoyed. Maybe he should make her into one of his pets...
