Go hard.

You run your fingers down Power Girl's body. You savour the sight of her naked before you, trembling at your touch and intent. She's so weak and frail now compared to what she used to be, compared to how you are and will always be. You understand why it scares her, but you also understand the things intrinsic to all versions of Kara Zor-El. A need to love and be loved, to be unburdened of power and embrace being small and protected, a deep rooted masochism. You slide the head of your cock against her wet kryptonian kitty, pushing in ever so gently just now to ground yourself, your aura taking hold of Karen's body to ensure you can't slip out. You take one of her large, soft breasts in hand and squeeze, sinking your fingers in deep and hard as you knead the flesh in your iron grip. Beneath you, Karen moans in pain and pleasure, her noises identical to those of her alternates.

"Y-you're hurting me..." She whimpers, reaching out, grasping onto your shoulders, holding you close as her back arches and pushes her famed mammary into your grasp.

"Supergirl likes it when I hurt her..." you lean in close to whisper to her. "Begged me to rip her costume to pieces and fuck her hard. The rougher I treated Satan Girl, the more compliant she became. You're a Kara Zor-El, the same as them. You want me to hurt you, you want this to be rough."

Her reaction is quite what you expected. Tears blossom in her eyes as she clings to you harder, her voice weak and trembling.

"N-no-one's... c-called me Kara in... so... so..."

You kiss her passionately, your tongue raiding her mouth as she grips you like her life depends on it, your grip on her breast never abating. You pull back and kiss at the tears streaming down her face, every part of her will belong to you, including these.

"Shhhh... It's okay Kara. You don't have to be strong any more, you don't have to pretend anymore. Just let it hurt. Let it feel good."

She nods, and you kiss once more before you catch her off guard by driving deep into her tight body. She moans and trembles in your hand, her skin prickling as your aura reaches through her. She has now powers right now, and you aren't planning to be gentle, so it's up to you to keep her safe.

You give her no time to rest or adjust, quickly building to a super-human rythm as you slam into her with the same kind of **** you recently fucked Supergirl with. Even with her kyrptonian physiology, it's all too much for Power Gir's powerless body. She bucks and screams and orgasms swiftly from the forcefully stimulation, only to find no release as you keep on going, keep on driving harder and faster.

"I-I can't... breathe!" she chokes out, struggling to take a breath. Your only response is to slap her hard accross her naked, shaking tits and make her scream out a little more of the air in her body. You can see the flow of energy in her, you know where the safety line is, she has to learn that this too is under your control.

You lose count of the times you make her cum. But you hold in your mind the one that pushed her over the edge, her eyes rolling back in her head as she made her cutest, most pathetic noise yet and slipped into the borderlines of concious and unconciousness. Her body even more soft and pliable now in your grasp you didn't stop, fucking the beauty of her weakness into her **** form. Until, at last, you too climaxed, pouring your seed into her ready and willing womb.
