Two possessor demons

As the two were led out, Danny wondered why the two of them, sure he was talented sexually, but they mostly wanted him for his sperm. "I wish I never crossed paths with the charmed ones." Kira said as she walked. "So you wouldn't be held captive?" Danny asked her. "And I'd still be a virgin." Kira told him. Danny found this surprising, especially with how attractive she was. "You were a virgin? I'd figure an attractive woman like you would have had dozens of men trying to get in your pants." Danny told her. "Yeah, but I'm a demon, and most demons aren't that attractive, plus some of the visions I had of humans caused me to sort of want what they had." Kira said, looking down at the last part, as if being alittle ashamed of having human emotions for a demon.
Once they reached a bedroom, two humans stood there, one male, one female, both attractive. "These are the two?" The male asked Paige. "Yes, are you sure this will work?" Paige asked them. "What are you talking about?" Danny asked her. "You see, there are two people who naturally exist that if you were to fuck and have kids with, would result with a type of child we're looking for, one is the ultimate power, Billie, the other is Kira." Paige told them. "What?" Kira said in shock. "Yes, you're the female version of him, that's the reason you're still alive, and these two possesor demons are going to control your bodies and have you two fuck." Paige said, "Now I'm going to leave you four alone, have fun." Paige said leaving and smirking.
The second Paige left, the two demons disappeared and took over the two bodies. "This will be fun." The male demon said in Dannys body. "Yes, it's nice being in a well endowed body again." The female demon said in Kira's body, kneeling down and preparing Danny by giving him a blowjob. Thanks to decades of sexual possession, the female demon gave a spectacular blowjob which got Danny hard and cumming in under a minute, and due to the male demons experience, he could stay cum hundresd of times without going soft. Also due to their magical abilities, they could fuck for days staight and the body would survive after they had left it.
