Yes (female)

To say that James was surprised when a cloud of glowing blue smoke which crackled with power began to billow out of the lamp would be an understatement. It happened so fast that James did not have time to react before the swirling magical energies solidified into the shape of a dainty young lady dressed in an outfit that consisted exclusively of a pelvic curtain and jewelry."Greetings, Master. Your wish is my command." The mostly naked woman said in a posh accent as she bowed towards James.

James's jaw went slack. "...the fuck?"

"Quite correct. I am a sex genie. Here to fulfill your carnal desires and make your most erotic fantasies a reality." The genie saw the look of doubt on James's face. "I know it is hard to believe. I imagine that you are wondering if this is a dream. Do not take my word for it, Master, test my powers for yourself. Make a wish. The only real limit is that it must be sexual in its foundation."

"That seems like an odd limitation." Said James.

The genie shrugged. "The Powers and Dominions which sanctioned my creation feed on libidinous energies, they help fuel my power with the extra getting passed up to those above who read our lives like a story."

James furrowed his eyebrows as he contemplated the idea that his life and his world was nothing more than someone else's fiction when he remembered that his family was on the other side of a very thin wall. "Can we not do this here and now? I do not want my wife or kids walking in here and seeing us together with you dressed like that. My marriage is bad enough as it is and I really do not need you making it worse."

"So, you wish for your marriage to improve? You wish your wife was more attentive to your needs?" Asked the genie.

"Sure." Said James.

"See. That was easy." The genie said as she snapped her fingers. Sparks of magic crackled from the genie's fingertips. "Ohhh. It has been so long since I felt the rush of magic." The genie looked at her new owner with thirsty eyes biting her lip as she imagined the man naked. "Does Master wish for some privacy, or should this **** make herself scarce?"

Before he could ask what the genie was talking about, there was a knock on the door. "Jimmy." said Karen.
James's eyes went wide as he imagined his wife's reaction. James gestured in a panic for the genie to get back in the lamp, the magical sex **** giggled and disappeared.

Karen opened the door to find James alone. "We should talk, sweetie." said the middle aged woman who James realized looked twenty years younger with a body that was much fitter than she had ever been. "I owe you an apology. I have not been a very good wife."

"What? No. Honey, you. I mean. We have been having a rough patch but..."
"But nothing." said Karen. "I am supposed to love, honor, and obey you. That is what I am going to do from now on."

James genuinely could not believe what he was hearing. His wife was a proud feminist. Someone who blamed the patriarchy for everything. "I don't understand." said James.
"From now on. All that I care about is making you happy." said Karen before she got down on her knees and took her husband's semi-erect cock in her hands and started to give it a tug as she teased the tip with her tongue.

James could not believe it. In all his years of marriage, Karen had refused to ever, ever give James oral sex. Though she had demanded that her husband go down on her as a sign of devotion, Karen had always considered blowjobs to be demeaning humiliation, until now.
