"O Slut, you're really going to regret doing that", he growled, calmly wiping he sputum from his cheek. "Spitting, really, is that what your Momma taught you?"
"I'd do a lot more to you if I could, you despicable worm", she countered, trying to regain at least some composure. "Just wait until I get free, and then you'll see what I can do"
"COULD do, Barbie, COULD do", he smirked. "Right now, calling me names is about the top of your action capabilities. Anyway, about that pretty collar that you're wearing. You know, it's got another feature that this seems to be the right moment to share with you. You've obviously realised that it rather neatly cancels out those pesky Kryptonian powers of yours; but even more interestingly, it was also built with Pym technology..."
"P-Pym technology" she stuttered nervously. "What are you going to do, shrink me?"
"Maybe later honey, then you really could be Barbie" he smiled evilly. "But for now, I think we'll try the opposite"
"G-Grow me?" the mystified maiden started. "But why?"
"Oh, not all all of you, there's no fun to be had there. But with this", as he produced a remote from his pocket, "I think we'll all find interesting".
Still confused, our heroine looked blank; meanwhile the guards grinned lasciviously. At the press of a button, sudden stabbing pain lurched from her neck to her entire chest. Both of her beautifully-formed breasts were fully inflamed She was desperate to grab them, but her arms still being bound, she could only grimace in agony.
"What is happening?", she howled. "You can't do this to me - I'm Supergirl!"
"Maybe once bitch, but not any more", her tormentor again delighted in her pain and confusion. "In fact, I thought that 'Supergirl' deserved some really 'Super' Tits".
Finally, Supergirl realised that her chest was getting heavy. She realised with horror that her once perfectly-formed breasts had at least doubled in size, and were still growing.
"Bet those gjungas are starting to feel pretty sensitive now aren't they SuperTits. How does this feel?" He grabbed a breast in each hand and kneaded them like overworked dough. She squealed in despair, completely powerless to prevent this latest humiliation.
"Puh - Please don't do this to me" she whimpered. "They hurt so much. They're too big. How can you expect me to function with these monstrosities stuck to my chest?" Her back arched, her slender frame trying to support new weights that without her former strength. And still they swelled, and grew, and his continued manipulations sent spasms of agony ricocheting through her body.
"No!" She screamed.
After minutes that felt like hours, he finally let her go. Her hyper-sensitized breasts were each now literally the size of basketballs, but impossibly still proudly uplifted with thumb-sized nipples reaching to the heavens. Now struggling to support her own weight, and exhausted from the various brutalities and indignities, she had endured she collapsed against the chains that bound her.
"Ok boys, let her down - let's see how she copes with her new friends..."
