Turn the mansion, a link to her power, into a sex den.

You mull your head for ways to corrupt poor Alusia, as you look around you realize the mansion is the perfect size for not only a religious army, but also a sex crazed dungeon of monsters and fiends. You smile at the promising prospect and look at Alusia, "From now on you and this mansion belong to me, I'll bring in whatever manner of monsters here and you will suck them off one by one. You will take in their corrupt seed and spread it, and maybe then you will finally learn your place." Alusia wilts at your words as the tears are now falling freely, "Yes master."

"That's a good slut." you coo into her ear. "Now suck my cock." you tell her. Alusia widens her eyes at the order, doing such a thing was unnatural and even sacrilegious for a goddess of purity, "NOW WHORE!" you slap her viciously and grab her by the hair, she unwillingly lowers her head onto your cock, her pure lips and tongue running along your veiny shaft, she looks up at you in what she thinks is defiance, but as you look down her face is covered in tears and a look of defeat is etched permanently onto her, and the sight of your cock nestled comfortably in between her soft lips sends you over the edge. You cum deep inside of her mouth, she retches at the slimy texture and bitter taste and spits it out onto the floor. "Now now slut, we can't have perfectly good cum go to waste can we?" Alusia looks terrified at what you're implying and shakes her head no. You sigh and grab her by the back of her head and **** her face into the pile of cum. She cries out and gags as the cum is **** into her mouth and nostrils, even still she refuses to drink but after a few solid kicks to the gut she laps up the cum like a filthy dog. You let go and Alusia remains there, weeping and limp in horror and pain.

"I'll be back ****." you tell her as you go out to retrieve a few friends to join the party.
