Take control.

The room is indentical to the one you used earlier. You loosen your costume as you walk in and take a seat on the bed.

"Come, sit." You gesture to the spot next to you. Power Girl is in a precarious place right now, and thinking of Supergirl crying beneath you from the weight of the world you know it will take more than gentle words to get through to her. Thinking of Satan Girl being brought into obedience, you know you will have to take a Kara Zor-El by the reigns and dig in the spurs.

"I... yeah," She obeys, tugging at the hem of the tee-shirt to cover a little more of her thighs as she sits next to you. The top has to be big to cover her chest, but those same cosmic scale boobs keep it from hanging as low as it could. "So... did... you come here to 'get serious?'" she alludes back to your kiss, trying to flirt with a sad smile.

"Yes, I did." Your tone is somber and Power Girl's eyes go down. "I already know... they can't help you get your power back, right?"

Karen nods her head. "It was a lot of magic talk, red kryptonite is weird... but yeah... my body just... can't turn sunlight into power anymore. Poof... the end... hello powerless girl..."

"Good."

Your word startles her, the exact opposite of what she had expected.

"Good? I... I've lost two worlds already, and now I can't protect this one and you say that's 'good'?"

"Yes. I do." You turn to face her. "That power is why you and Supergirl think it's your responsibility to protect this world, unable to move on from the pain of your loss because of this sense of responsibility, this sense of fear. It's not good for either of you. That's why I've stopped Kara from being Supergirl, and I'm going to do the same to you."

She barely has time to think before you seize her chin and pull her into a kiss, her instincts opening her mouth and letting you in as she clings to you and trembles.

"Wh-wh what do you mean?" she asks, shaking as you pull away, before letting out a squeal as you push her down on the bed. The once mighty Power Girl, helpless putty in your hands.

"I'm making a mother out of her. I'm going to keep her happy and pregnant, her responsibilities will be to me and our children." You straddle Karen's waist, stripping off your costume. "I'm going to do the same to you. She wants me to do the same to you. For us all to be together and happy. Leave saving the world to me."

"I... uh... wha... I..." the former heroine babbles, offering no resistance as you grasp the tee-shirt and pull it up over her head, revealing her to be naked beneath, her famous, marvelous breasts rising and falling with her startled animal breaths. "Wh-what if I say 'no'?"

"You're not going to." You say with certainty, fully stripped and giving her a view of the monstrous shaft that will soon impregnate her. And yet, you still pause a little, slowly grinding your shaft against her wet slit, making her tremble, wanting to hear her admit it.

"N-no... I'm not."
