Time to make them pay

You build your power and attack their minds. Both were still consumed by their pleasure when your attack pierced their lowered mental barriers and took control of their minds. However, you decide not to take full control of their minds.

Instead, you tweak their minds to make them lose all their powers. You also use your powers to make them lose any powers in their limbs. "You bitches! You tormented me for so long. Now it's my turn."

"Get down on your knees." Both of them refuse to move. "You can choose to resist but then don't blame me for ravaging your ass" you tell Phoebe. You can see the scared look on her face as Karma hits her hard. She decides to cooperate and get down on her knees.

"And what are you waiting for?" You ask Max. He also gets on his knees. "Do I need to tell you both what to do?" You tell them as you pull down your pants to reveal your erect dick. Phoebe tentatively holds your dick and gives it a lick.

"Every dog has it's day." She says as she starts her administrations on your dick.

"And karma is a bitch, just like you. So today, this dog will have fun with this bitch." You tell her as you shove your cock down her throat till she gags. "Relax your throat" you order and then shove rest of your length down her throat. You let her have a gasp of air before throat fucking her again.

"What are you waiting for? Join her in sucking" you order Max. As he licks your dick, you bring his head closer to Phoebe's. "Kiss each other while you lick my tip." you order them. They are completely revulsed by the idea.

"That's sick. She is my sister."

"That's sick. He is my brother."

They say at the same time. "Were you not siblings when you were having sex with me together? Now you will still have sex with me together or I can simply control your minds and get you both to have sex with each other in front of entire academy." you threaten.

They kiss your dick's tip touching each other lips unwillingly. "Properly" you order them. They follow your orders and show you a proper kiss on your dick's tip. You feel your cock twitch as these sadistic actions bring you further pleasure.

"Are you satisfied now?" Phoebe questions you after kissing Max.
