Daring adventures, harsh training.

About 10 minutes after Steel briefed you on a strange set of super science thefts the kaiju attacked. You were 100% certain that the two incidents had nothing to do with each other, but that just made it worse. It was a harsh reminder that when things hapened in Metropolis, they happened big, and you had to learn how to juggle with dynamite in order to keep up.

Back in your hotel you continue to dicipline Kara. The more you screw with her brain, the more stupid and animal like she gets, the less she understands your words. Her rapt attention to the sound of your voice, yet her dumb expression as she fails to comprehend your words is soothing balm after a hard day. Sure, giving her instructions would be easier if she knew what she was being told, but there is great pleasure to be found in wrangling your fertile little teen.

For instance, drilling her status into her. She's only allowed in or on the bed with you. No pets climbing on the furniture. Once you're awake and up you make sure to tip her onto the floor, often shocking her awake in the process. Further, the floor is where she belongs. It took getting a little extra rough to make that one stick in her head. Sure, there was some praising and petting when she crawled around on all fours like the cow she was becomming, but if you caught her standing up right you were swift to drag her back down to the floor. She would look at you confused about what she did wrong, often trying to stand back up. You would give her space to make that mistake, she had to try in order to learn it was wrong. She would reel as you slapped her for the attempt, striking her beautiful face or full breasts and barking 'no'. Eventually she understood, and your good girl made you proud.

And so you wake early each morning, wrapped in a beautiful, stupid girl. Squeezing her body until she moans before dropping her to the floor. You leave no food out for her. Food is for people. You want Kara to subsist solely on sunlight, to better understand her Kryptonian physiology, to see how tight you can make that waist before it swells endlessly with children.
You investigate the thefts, you fight monsters and the occasional robot. You help the city, find lost children, and make everyone feel safe. Then you go back to your hotel, and fuck the throat of the one-time Supergirl, and **** her as you have sex, killing every last bit of personhood in her mind as she gratefully cums around your cock. One day a reporter asked you 'do you have a girlfriend?' and as you thought of Kara wearing only her bright collar, basking in the sun or begging for your attention you honestly said 'no'.

In time you put together the plot behind the super science thefts. Veronica Cale, discount Lex Luthor wannabe had been behind it, working a half baked scheme to put together her own mobile super weapon. If the kaiju didn't start as part of the scheme, it sure ended up as one. Stolen from the lab it was contained in and converted into a collosal cyborg. The battle took hours, but eventually the monster was defeated and Veronica arrested.

As she was led away, part of you wished they would skip prison and just hand her over to you. Let you wrap your hands about her neck and **** away those corrupted brain cells of hers, all while putting a nice healthy baby in her womb. The world could do with fewer evil geniuses, and more dumb pet girls.

You arrived at the hotel late, having stayed out to help with clean up and rescue work. Kara crawled across the floor to welcome you back, her vaccant eyes smiling happily up at you. The sight of such a good girl exactly what you needed after seeing a bitch like Veronica Cale. In a primitive way, Kara senses your agitation and anger. Taking your hands, she guides them up to her neck, gazing at you with animal love and adoration. She wants you to feel better. She wants you to hurt her. That night is the roughest sex you've had so far, for the first time truly 'using' Kara.

You **** her, strike her, fuck her hard while pinning and twisting her body. You don't do it to train her or teach her, but to enjoy her. Her enslaved insides clench tight about you through the pain as Kara demonstrates that she has decended past human, below cattle, and to the point of 'thing.' You cease to think of Veronica Cale, your mind having room for only one big titted blonde. The anger fades, the frustration passes as you take pleasure in using the former Supergirl. Even when she collapses into unconciousness you keep going, and her body keeps responding, her own mind not necessary for what she was born for. Eventually, you come to a stop, and wrap the sheets around yourself and your thoroughly loved and abused girl, her **** smile filling your sight as a meaty breast fills your hand as you drift off.
