Magic makes it happen.

With your aura supporting Satan Girl's mortal body you have no need to hold back, only hurting her as much as you want her to be hurt, as much as it's fun to hear your masochistic teen cry out as the pain makes her wetter and hotter. Your fingers roam her body, finding weak points to grope and strike, intoxicating her with your domination as you fuck her to save her life, to put a life in her, and to enjoy this delicious doppleganger.

In your Aura Vision you can see the dance of electricity along her nerves, the sparking pleasure in her brain as it dwarfs all other thought and impulses. Satan Girl looked stunning in her skimpy costume, but helplessly rolling in your arms is definately her best look. You can see something else in your Vision though. The little bit of light she has left is flowing through her body down to her womb, pouring into her ovaries and stimulating them. It does not seem to be a concious effort, rather simply a natural reaction of her body. Perhaps in submitting to you, Satan Girl has ceased to be 'Supergirl's Shadow', and her existance is now becomming based on being 'your girl.' Really, it's a question a mystic master would be better placed to answer, what matters to you is how good she feels, and how much more excited you are to see her body using some of its precious light to **** out an egg to meet you, to ensure that she gets knocked up here and now.

"You want it so bad don't you, to get knocked up, to be a little teen 'stay-at-home mom'," you growl as you pound her harder, making her scream as you unleash super human strength and speed on a mortal girl. "You weren't created to fight Supergirl, you were created to be fucked by me!"

"Yes... Yes!" she claws out the words, her weak fingers desperately gripping you. She's too weak to try and respond to your actions, instead offering everything to you. If you grant her a moment of movement, she uses it to show more of her body, present herself for your use and revelling in your touch. More than that, the promise that she exists for something 'good' seems to please and excite her. A demon dreaming of domestication.

You slow for a few moments, kissing her on the lips, rolling your tongue around her mouth and biting down on her lip. She purrs and moans, her mouth hot and **** for you.

"I'm going to go hard now." You promise, gently brushing her cheek. There are tears running down her face and she doesn't know why. "Don't resist, don't do anything. Enjoy it, let me break you and remake you... let me breed you and love you." You take one of her large breasts in hand, your finger trailing around her pointed nipple and making her shudder as your fingers sink into the flesh and squeeze. "When you wake up, you'll be a whole new girl."

She tries to talk, but your words and the feeling of your cock in her tight, teen body leave her mute save for a small moan and a roll of her hips. She grasps you, kisses you, and closes her eyes.

From here on there is no art, only power. You press her against the rock wall and fuck her hard. Like a good girl she cums hard around your shaft as you get serious. She doesn't fight any of the orgasms that come as you thrust into her body, your aura bouncing through her nevers to spike and amplify her feelings. Her eyes open briefly at one point as she screams, before rolling back in her head before she becomes even limper than before. Normal girls aren't meant to be bred at mach 5, their little minds can't handle the sensation, but it feels so good. Even as she's **** you keep going, fucking out everything Satan Girl was to turn her into the new girl you want her to be. At last, you let yourself cum, erupting with a growl as you bite down on your lover's **** neck, a primal desire to own your breeding partner.

Once your senses even out, the burning joy of ejactulation cooling, you look down in your Aura Vision to watch as the solar enhanced egg is met by your perfected sperm. This is the end of Satan Girl, and the beginning of something wonderful.

Bundling the **** girl in your arms, you look and see that at some point in your brutal love making her boots had faded away too, the last trace of the girl she was. Unconciously she stirs, leaning closer to your body. Smiling, you make your way out of the cave, your aura protecing you both from the water as you head for the surface to rejoin Supergirl and Power Girl.
