What's their first move?

Vicky Grabs Charlotte.

"So, I now wish to... HEY!" Charlotte said as Vicky grabs her from behind. "What are you doing, Kelly?"

"My... name... is... VICKY!" Vicky said as Michelle discarded her human disguise and pounced on the camerawoman, knocking the camera to the ground. "I've been putting up with your bullshit for too long, now you're going to remember who I am, for eternity."

Charlotte watched in shock and horror as Vicky's clothes burned off as she orgasmed hard. Her transformation was quick, her skin turning a deep red while her hair grew out, becoming jet black. Her wings and tail burst out as she became a Succubus, a flaming whip forming in her hand as she glared at Michelle, holding her down.

"I am no longer your bitch, you are going to be mine!" Vicky said, sitting her pussy down over Charlotte's head and cracking the flame whip over her. "Eat my pussy bitch! Become MINE!"
