You gulp nervously.  "Um... Mind if I just look at the features on this real quick?" you said.  "I'm still trying to process all this." 

 

Catwoman nodded easily, relaxing and plopping down on the couch next to you.  "Sure thing, Master," she said.

 

You nod, and call up Catwoman's profile again.  Something catches your eye immediately. "Personality?" 

 

Catwoman nodded.  "Right now, I'm set to 'Friendly' and 'Willing.'  You could set my personality to be anything you like.  Shy, bold, unwilling, my original personality... there's a yandere setting, but I don't recommend that." 

 

You blinked.  You know you've heard that term somewhere... "Is that anything like tsundere?" 

 

"Hahano," Catwoman said, her expression serious.  "If you make me yandere, then I'll kill everyone around you just to have you to myself.  And then if I think you've betrayed me in any way I'll torture you, probably to death.  Yandere is essentially the phrase 'crazy in love' taken to extremes." 

 

You gulp nervously.  "OKAY.  Let's never use that setting," you said.  Turning back to your phone, you decide to leave Catwoman's brain alone and play with her physical features.  

 

Almost immediately, your eyes fall onto the breast size controller.  There's a toggle next to it marked 'Lactation? y/n,' and just for kicks, you toggle it to yes.  After a moment's thought, debating whether or not to just scroll it all the way to the top, you decide to take it slow.  Staring at Catwoman's chest, you watch as her boobs swell in size, damp milk spots appearing on her costume.  Catwoman quickly becomes uncomfortable, gasping softly as she touches her sensitive, swelling breasts.  She unzips her top and pulls down her bra, letting her swelling jugs hang free.

 

"Much better," she said, stroking the swelling globes as they filled with milk, her nipples going fully erect and leaking.  

 

You stop once Catwoman's breasts are bigger than her head, the master thief purring at you.  "Feeling thirsty?" she teased.  "Or did you just feel pervy?"
