Supergirl

A familiar face filled the screen, blonde hair framing her face, and Lois shivered. The camera panned down, the almost skin-tight suit hugging the Girl of Steel's athletic, toned, perfect body. The background of the picture was a blank field of color that pulsed slightly between white and pink.

"Have you ever wanted to be perfect," she said, and Lois was drawn to the slight, almost barely visible swirls in the the background, before focusing back on the face. It looked like Supergirl, it sounded like her...but the things she was saying weren't things the Last Daughter of Krypton would say. The reporter suspected this was a computer-generated model...a deepfake, to create a commercial.

That perfect smile appeared on the camera. "This can be yours. This can be you. A little bit of my Kryptonian DNA is in you. Changing you. Making you...like me. Perfect."

The sun lamps against the walls began to heat up. Lois worried for a moment, but suddenly felt...good. All the aches, nausea, and fever she'd been experiencing vanished in moments as she soaked up the rays.

The background behind "Supergirl" was visibly pulsing now. The camera panned back down, as the blonde began to disrobe, revealing pale, perfect skin, the subtle swell of muscles, the outline of strong bones...and a tiny S-shield cut into the blond fur that hit her crotch. If not for that, Lois wouldn't be able to tell that this was Supergirl at all.

The lights continued to intensify, and though Lois knew she should start to feel the burn from the lamps, it felt no more than being out on a summer's day...albeit naked.

"You will never be sick again. You will age slower, process toxins faster. But that's not all."

Lois shuddered at this implication, and looked around the room as the Supergirl commercial continued her pitch. The faux-Kryptonian's hands clutched and pushed her tits together, talking about how they would never sag or droop, no stretch marks either... The background seemed to be pulsing faster, the patterns more complex, and Lois had to focus hard to concentrate on the words and not just stare at her massage her tits.

"...Kryptonians experience transformations when exposed to some varieties of kryptonite. For us, these effects are temporary, but for you, the effects can be permanent...if you want them to be. Imagine a natural breast augmentation, with no surgery or healing time. Or an instant, perfect gender reassignment for transgender individuals. Even more exotic options are available for those who suffer from body dysmorphic disorder..."

The light was almost blinding now, even with the goggles, but Lois felt...alive, almost burning with excess energy. Even the tinge of pleasant alcoholic haze had vanished. Unconsciously, she found she was massaging her own breasts, just as Supergirl was on screen. She felt better than she ever had in her life...but also deathly afraid.

"...expand your body and mind, experience what it means to be...super!"

Lois wondered about the other women, who had stood where she stood now. This sort of treatment had to be experimental...even if it worked, there could be side effects.

"...we are now going to administer a change in you now." Supergirl said. The camera panned down to her crotch, to one perfect hand rubbing at it, back and forth. Lois felt her own pussy itch in response. The background behind the Kryptonian's crotch was pulsing fast and furiously, things moving in between the flashes, strange obscene shapes Lois could not focus on... "Stand still."

And Lois did.

A panel disappeared from the ceiling, and a small arm began to descend. On the end of it was a chunk of crystal. For lack of better options, Lois steeled herself. Whatever was going to happen, she couldn't run from it.
