Make her beg.

Jaune of course let an orgasm hit him, but didn't ejaculate. Weiss blinked and looked back as he stopped for a moment. "Daddy... Why did you stop?" she whined.

"Catching my breath, just orgasmed... I only ejaculate at will at this point, or in response to making a girl cum..." he replied, beginning to move again.

"Hngh," she groaned through grit teeth. "Daddy... I need to cum..."

"No, you want to cum, you don't technically need it," he teased, pounding into her ass.

"No, I want it so bad, I do need it, I will go crazy if I don't!" she whimpered as her ass clamped down on him.

"Hmm... Convince me to let you cum," he grinned, loving this little game.

"D-daddy, please take care of your little slut, I want to serve and obey you, please let your slut cum..." she gasped out, her ass producing slapping sounds every time Jaune's hips hit her.

"Keep going..." he said, slamming his hips into her from behind.

"Nnnh... Daddy, please, this bad little girl will be good if you just let her cum... I want to please you so bad, but I also want my reward for it..."

"Alright, you've convinced me," he said, grabbing her hair, and pounding her ass even harder.

"Ah, yes! Let me feel it!"

"Cum Weiss," he ordered, leaning over her, and putting a hand over her mouth to keep her from screaming.

"Mmmph!" she gave her muffled scream, and he barely held his own voice at a controlled level as he filled her with his seed. She collapsed, taking him down with her as he laid on top, and they wheezed as they caught their breath. "Th-thank you Daddy," Weiss panted out after Jaune removed his hand from her mouth.

"Good job Weiss, he grinned, pulling out, just as his teammates returned.
