Mutate the police woman

"Yes, that's right, I've got a grey Ford sitting here. No plates or identification," the officer, one Alexandra Janson, reported through her radio. "There's signs that it was driven recently. No sign of the driver. Should I call a tow now? Over." Kelly slithered out of the bushes and reformed to her full human shape as she casually walked up behind the officer.

"Excuse me, but that's my car."

Alex turned around to see... "Kelly Brook?!" the officer gasped. "What are you-mmmph!" Kelly's mouth was on Alex's and smothering her with kisses. Alex was no lesbian, but she felt oddly hot and aroused by this sudden show of affection... even as Kelly's body began absorbing her, clothes and all. Unlike the stalker, Alex would feel no pain as her mind was too drowned in lust to feel her dissolving body as anything but the greatest orgasm of her soon-to-end human life. Kelly's body lost all human shape as she pinned Alex to the ground and melted themselves down into a singular blob. Only the metallic parts of Alex's uniform, namely her badge, radio, and gun, were left behind.

After the greatest two minutes ever, the single blob split off into two and each reformed into a visibly-naked female form, one being Kelly, the other being Alex. Having been given a full explanation of her new capabilities during her time merged with Kelly, Alex flexed with inhuman glee as she felt just how formless yet powerful she now was.

"You go back to your patrol," Kelly ordered. "If you find anybody worth mutating, do it covertly. And if anybody gives you trouble." She licked her lips, a gesture which Alex understood perfectly as she felt her own hunger grow. "Meet me at my villa when your shift is done."

Alex nodded and used a slime tentacle to pick up her dropped radio. "Never mind. I found the driver. She's going to move it now. Returning to patrol, over." Realizing she was naked, Alex focused on her flesh and summoned a perfect facsimile of her police uniform to form on the surface. Re-equipping herself, she got into her car and drove back into the city. Kelly morphed a skimpy black skirt onto her own form and was soon driving back to her villa.

The Mutant Slimes were here... and humanity was about to get a whole lot gooier.
