Agree.

You continue to stroke Supergirl's hair and back, comforting her as best you can as she shakes in your grip. Earth is a second home for both of you, but the circumstances are very different. When you left, your Father and mother saw you off, so many of your siblings bade you good bye and good luck. You recieve messages from them, can visit them. Kara Zor-El's world burned. Everyone she loved was lost. She came here as a refugee, a kind hearted girl whose concience was demanding she use the great powers she recieved for more than her mind could handle.

"No. No I don't think you can," you agree.

She pulls back to look at you, surprise on her teary face. She likely expected you to argue back, to try and give her a pep-talk, or say how the world needed her. No. The world had plenty of heroes to fight to save it, it could afford to have one more damsel in distress.

Gently you kiss her, her eyes sink closed as she kisses back. Her mouth yields to yours, comforted by your strength. She purrs as your aura ripples across her, dispersing the dust and grime that clings to her body. Not as good as a full shower would be, but enough to clean her.

"I know I said that continuing to be Supergirl was your choice... but I don't think it's good for you. The stress is breaking you apart..."

"B-but... people need me... If I have this power I need to be responsible... I... even if I hurt I..."

She starts to babble. Justification after justification spilling forth. Chained by her concience and kind heart, she's going to keep breaking herself unless someone stops her. Tears keep falling from her eyes as she looks at you, her expression pleading. She wants you to stop her. She wants you to save her.

You cut her off with a forceful kiss, and she moans as you silence her.

"No. You're going to have plenty of responsibilites." You tell her, dropping to your knees and lowering her to the ground, her golden hair spilling around her head. "I've cum in you once already. You're going to be a teen mommy," you kiss and nip at her neck, loosening her grip on you with pleasure, getting access to her body as you stroke, pinch and grope away her thoughts. "And I'm not going to stop. We're going to have a big family remember? I'm going to make sure you have at least two kids before you hit 20."

Her legs spread and she moans as you slip a hand between. She's already getting wet.

"We'll have so many children... they'll all need looking after... so much love..." you punctuate words with kisses, wiping away tears with affection. "I promise... I'm going to keep you very busy."

You sit back and begin stripping off. You'll apologise to the medical team later, but you know what your girl needs right now.

"You can keep making excuses Kara. But I'll keep knocking you up. There'll be no Supergirl because I'm going to keep you barefoot and pregnant in the kitchen, where a girl like you belongs."

Her eyes light up as you lean over her, taking her hands and pinning her to the ground. She gives a token struggle against you. Her power is real, able to snap mountains and holding her down is no casual effort. Even magically reinforced the ground beneath her cracks from the strain and struggle. But she cannot move you, cannot get up, and the more clear that becomes the more she smiles in joy, relief and desire.

"The only one who should hurt you is me."

Her eyes widen as she remembers her own words. How she begged you to hurt her. To love her.

"Please... make me... I love you." She whimpers, sinking into meekness.

You kiss her before ramming into her. You make her scream as you fuck her. You reinforce that she is Kara, big tittied school girl out to be a mommy, you make her forget about obligations to anyone but you. You shake the earth and stir waves as you hold nothing back. The cavern can protect itself.

After you finish inside, you hold a hand over her stomach, affirming your intent to see her happy and pregnant. You redress and bundle her in your arms and begin to make your way to the surface when she makes one small request of you.

"Please... save Power Girl... save Karen too..."
