Viktoria's Secret #8

Viktoria checked her watch and her computer repeatedly.  It was that time of the month again.  That damned old crone with her magic curse (who believed in that kind of thing these days) had made sure Viktoria, once a month, changed.  She'd been everything from part snake to part fish to part snail to ... just about anything imaginable over the past seven months.  She wondered if the curse's batteries would ever run down and just let her be.

The first hint of the change came early this time.  Usually it was well after midnight before anything got started.  This time the change started at 10 PM.  Viktoria felt something swishing across her legs and, checking the strange feeling, discovered she had a tail.  Not just any tail -- a horse's tail.  Shiny and dark and unbelievably tangled.  Viktoria did her best to straighten it out with her hairbrush but didn't completely succeed.  While she was occupied with the tail, short brown fur grew in from her waist to her feet.  Her feet became too painful to stand on and Viktoria watched as all her toes save one began to shrink.  Her middle toe grew until it was easily as long as her feet had been.  The feet were thinning and changing shape before her eyes.  It didn't take too long before her single toe had developed a hard horny cover -- in short she now had hooves in addition to a tail.

For a while, nothing else seemed to change.  Viktoria wondered if she was done when she began to feel dizzy.  Her rump was growing, stretching backward into something huge and monstrous.  Viktoria had worked hard to keep her figure and to suddenly end up with a huge butt was more than she could take.  The growth eventually stopped, leaving her with what looked like a two legged horse attached to her waist.

After a few minutes, Viktoria noticed she was getting large in the belly.  The growth swelled until she looked like she was nine months pregnant.  Her stretched belly hurt and she rubbed it to help ease the pain.  When she thought she could stand it no longer, two small sharp hooves erupted from her middle followed by a pair of forelegs that would have been more appropriate on a newborn foal.  This state of affairs didn't last.  The legs quickly lengthened and filled out.  Viktoria shook her head.  She was now a centaur -- well, more properly, a centauress.  She sat on her bed for nearly an hour, hoping it was all over, before she felt something push through her hair.  Sure enough, when she felt at the sides of her head, she now had a pair of horses ears to go with the rest of her new body.

She looked over herself.  She didn't look bad as a centaur filly, she decided.  Something, though, was bothering her.  There was something she wanted -- no, needed to do.  She couldn't quite figure out what it was.  Idly, she stroked the gradual transition from the horse fur to her own skin at her waist.  What could it possibly be?  It was important, even critical.  She couldn't quite put her finger on what it was.  She felt hot and moist in places she couldn't reach because they were between her hind legs.  Finally, it struck her.  The curse always struck when she was most fertile.  She was most definitely "in heat".
