He has them get on all fours to take them from behind!

"...need to make a wish for a recharge, Master?" Bella asked, breaking the kiss with Lydia.

"...no, I think I can manage another round... Both of you, get on all fours next to each other," he ordered.

"Yes, Master/ my Thane!" they both declared and quickly turned to face away from him, getting on their hands and knees, their rears presented. Bella glanced back at him, prompting Lydia to do the same, and they were both wearing radiant smiles, if a bit nervously in Lydia's case, Bella giving her butt an enticing wiggle, Lydia following suit.

"I don't have to worry about... Unintended consequences, do I?" Viktor asked as he knelt behind them, and started fingering their folds with a hand each. Lydia gasped and crooned, pushing her hips back.

Bella also moaned and shook her head. "Not with me at least, Master. While genies can get pregnant, you need to wish for it. Though for Lydia, you might want to make a wish to ensure you don't knock her up..." Bella moaned. "I'm also immune to STDs unless you wish otherwise. You can have the same perk with a wish."

Viktor nodded, and stated, "I wish that I could only impregnate a woman if I intend to, and that I and any woman I am intimate with would be immune from any STDs."

Bella nodded and snapped her fingers. "Wish granted," she crooned, pushing her hips back as Viktor's fingers worked into her labia.

"...so... Who are you going to start fucking first, my Thane?" Lydia moaned, even as her folds rippled around the fingers in her. Indeed, Viktor's member reached full mast again, ready to start going.
