Spider Queen (Patreon)

Five hours ago, they'd been enjoying each other's company at a campfire in the deep woods.  Then everything changed.  At first, they thought it was some kind of aircraft flying just above the ridge line but, when it stopped and hovered, they decided it was a drone of some sort.  Unfortunately, it was neither.  The strange craft had an electric blue glow that seemed to come from the craft itself and the very air around it.  It quickly came to rest above them and both lost consciousness.

Ten minutes ago, Carl regained consciousness by the stream they'd camped by.  His head ached and there was a strange electric buzzing in his head.  He looked up and collapsed to the ground.  The craft was still there, hovering above him.  But where was Catrina?  He wondered whether he should go for help or hide or something.  He discovered the best he could do was sit, anything else was somehow forbidden by whatever field the strange craft was generating.

Then a translucent metal cylinder extruded through the hull of the craft.  One by one, a series of strange steps of similar material flew from the open belly of the craft, positioned themselves like a step and expanded laterally.  Within seconds, a series of floating steps were in place reaching from the cylinder to the ground.  As Carl watched, the tips of eight metallic legs were lowered to the top steps.  At first, Carl couldn't make out who or what it was.  But when the creature was finally stable on the steps, he realized he was facing a giant metallic spider.  Struggling to escape, he forced himself to stand and run but found he lacked the coordinate. Falling backward, his gaze left the huge metallic spider to the apparition blended with the front of the monster.

"Catrina," he croaked.  "You're different."
"Nonsense," she replied calmly, looking down at her strange new body and holding her breasts.  "I'm exactly the same as I've always been."
