Viktoria's Secret #7

Woman: Erieye Stock

Many women loathe the time of the menses.  PMS and the general mess of that time of the month make it a time of misery for them and their significant others.  Viktoria had never been one of that crowd.  Now, since the curse, she'd come to dread a different time of the month.  Whenever she was most fertile, her body would change.  Not the usual water weight gain, not at all.  No, she would literally become something else.  She'd taken to sequestering herself a few days before the time and not seeing anyone until she changed back a few days later.  This was hard on friendships particularly her love life.

It was that time of the month again.  Viktoria could feel it approaching even if her cell phone's calendar wasn't doing a countdown.  The day before her expected change, she bought whatever groceries would get her through the five days, booked off work (thank god for an understanding boss) and retreated to her apartment.  The night of the change was always one of dread.  She could never be sure that she'd end up something that could breath air.  She filled the bath tub, just in case, and lay on her bed, reading.  

A few hours after midnight (no she didn't try to sleep ... she had to be awake for safety), she felt the change start.  Her legs became weak and began to elongate.  From her waist to the tips of her toes slowly became a dark brown.  Her legs soon began to fuse into a single large mass that grew until it was nearly 50 cm longer than the ends of her toes.  After a few minutes, it began to grow until her new tail was wider than her hips.  A bulge began to form about halfway along.  Soon she had a muscular hump.  This began to secrete a hard substance that, after a few hours, grew into a huge dark snail shell.  Two pair of muscular antennae developed from the sides of her head and her lower jaw.  Soon she could wiggle them disgustedly in the moonlight that streamed in through the window.

About five O'clock in the morning, Viktoria noted that the change had stopped and, because she was in no danger of having to make an emergency dash to the water, she allowed herself to sleep.  When she awoke six hours later, she found herself lying in a small pool of yellowish slime.  The tip of her tail, which hung over the edge of the bed, had dripped enough of the slime to create a significant puddle.

Viktoria, taking in her new form and the mess she found herself in, sighed.  She hoped the slime wouldn't stain things and would prove easy to clean up.  Something told her that, with her current luck, this wouldn't happen.
