They cannot but it doesn't matter

Conrad was on his knees eating out Miley. His face was covered by the fluid of her juicy cunt. Conrad wanted more, his entire being wanted to fuck her. He wanted to plunge his cock in her wet pussy and feel her tender breasts under his palm. Miley moaning only helps him make his decision. He would fuck her and fuck her hard he will be, but something felt a bit off. He felt his lust strong and hard, but his cock felt different than normal.

"Fuck me, I don't care anymore." Moaned Miley and it didn't take more for Conrad to be convinced to forget about the task he received a bit earlier. It was too much for both of them. Conrad moved back and began to slide Miley's panty down when he understood why he was feeling weird. His cock was all flaccid. Conrad could hardly believe it with all the lust, the moan, and the sex he should be hard as a rock. He never had difficulty achieving an erection before.

"What are you waiting for stud and plunge your cock in my cunt." Said Miley it felt weird hearing this from his girlfriend she was never in dirty talking before, but Conrad didn't mind much he had more important problems.

"I can't and I don't know why I really want to do it." Said Conrad pumping on his dick trying to get it hard, but unable to do it. Miley sat down to take a look at what was happening. That small interruption helps her regain some composure and control over her lust. She knew at that moment, that was much of a challenge for her than for Conrad. She had to take control of the situation or she would lose her opportunity to become the queen of Astaroth.

"Oh my, it's cute!" Began to say Miley overtly trying to humiliate Conrad. "I'll take care of it." Said Miley with an idea popping in her head. It was in fact, Astaroth sending her some hints in ways to corrupt Conrad.

"Put the panties back up and lay on the bed." Commanded Miley and Conrad felt the urge to compel. He brought the panty back up and felt a bit relieved hiding his inadequacy. Once he was on the bed, Miley climb over him and sat on what was his manhood now unable to get hard. She took his hands which seems a bit softer than before and put them on her needy breast and put her own hand over them for leverage. Once placed, Miley began grinding her pussy over Conrad's panties. She wanted to cover them with her fluid and make him cum inside the panties.

For some reason even if she didn't feel much pleasure out from grinding her cunt on Conrad, Miley could feel an orgasm building up inside of her. Conrad felt humiliated and yet very aroused by the situation. All climax a few minutes later, Miley exploded in a major orgasm feeling all her being been infused with power and Conrad felt his dick emptying itself in Miley's panties. Both fell asleep in puddles of womanly fluid and cum. The panties were infused with demonic power and mixed with his semen and Miley juice the magic grew in power and will change Conrad.
