Not like he has anything against anal!

"...you know what? Why the hell not?" he decided with a grin, and then told Diana, "I wish for a bottle of lube so I can fuck your ass."

"Granted, Master!" Diana nodded, snapping her fingers, and the bottle of fancy lubricant appeared in his hands as she placed her hand back on the toilet lid.

"God, you're so fucking hot..." Felix mused as he rubbed her ass, and she crooned at his touch.

"Mmmnh, I wouldn't be much of a Sex Genie if I wasn't, would I, Master?" she teased him as she pressed her backside into his hand. He chuckled as he pulled her ass cheek aside, preparing to pour the lube on her asshole.

"No, no you wouldn't be..." he mused, pouring the lube directly onto her ass, and she moaned. He then applied some directly to his cock, and lined it up with her puckered hole. "Ready?"

"Always, Master, please, put it in!" she moaned, and he obliged, slowly thrusting his cock past her anal ring. "Unh... So good," she moaned.

"So tight," he concurred, pushing all the way into her butt with some effort. He paused, giving her a moment to adjust, before remembering how durable she was, and that she was a Sex Genie anyway, and began to move.

"Oh... Ah... Yes Master, right there..." she panted, gripping the edge of the toilet, though careful not to crack it. In fact, her ass was gripping his cock tighter.

He pulled out until only his tip was in, before he thrust back in. "...why didn't we try this before?" he moaned, repeating the process.

"...because we were having a good amount of fun already?" Diana offered, pressing her backside back towards him, and wiggling her pelvis to bring them both more pleasure.

"...you bring up a lot of good points of late," he chuckled, speeding up as much as he could, given how hard it was to pull out and thrust into her anal opening. Still, it was well worth the effort, with how pleasurable it was.

So pleasurable in fact that he rapidly felt his arousal building. "Do I need to wish for you to cum with me again?" he panted.

She shook her head. "No, Master, this feeling is odd, but it's so good..." she crooned. "I'm quickly getting close too..." she assured him.

He nodded, feeling his cock beginning to pulse within her folds. "Then get ready, my little butt slut... I'm going to cum right in your ass..." he moaned. She gasped as he hit a sweet spot in her anal cavity, and nodded. She then cried out as her body siezed up in orgasm, her ass clamping down in an almost painful vice around his cock. He gave a loud grunt himself, and released his seed right into her depths.

She collapsed onto the lid of the toilet, and wheezed as he laid atop her. "That was so good, Master..." she crooned.

"...yeah... definitely doing that one more often..." he noted.
