It wouldn't be the same.
Frieren played a huge role in the demise of the demons. Aura has a reason to hate her. And just when Aura believes she has a chance to defeat her, everything gets turned upside down.
She is forced to be Frieren's servant; to orally please Frieren against her will.
Aura is also a pretty demon girl. If she doesn't swing that way, she still has to please another girl's pleasure points. Forced girl on girl action. Doesn't matter how much she hates it, her mouth and tongue is for Frieren to use. No longer having any control of her body, her brain can do nothing through a coping mechanism, in this case finding pleasure in giving pleasure to Frieren.
Month after month
Years go by
When doing nothing but giving oral pleasure
It would feel like an eternity
Nothing else to look forward to each day, Aura continues to endlessly lick and taste every inch of Frieren's body. At some point, she'd even be happy to serve Frieren as a toilet because her mind needs to find purpose in her existence. Every ounce of vaginal fluid that comes out of Frieren would be sucked and swallowed by Aura.
It just wouldn't be the same if it was any guy who would love to be in that position...
