Jen couldn't stand it any longer. Her hand shot up and Mr. Simms responded.
"What is it now Miss Smith."
"C..Can I be excused? I need to go to the restroom." She asked.
"Very well... but no more interruptions, this will be on the test."
Jen got up and tried not to run out the door. She closed the door and started down the hall*, feeling her pussy shift and contort even more. She rushed down the hall and burst through the door of the restroom, vaguely noticing that no one else was in the stalls. Hurrying to the stall farthest from the door - which also happened to be the largest of them - she darted in, before slamming the door shut and locking it.
Hurriedly, she dropped her near-empty school bag on the ground before practically ripping her skirt and panties off her body and tossing them into said bag. Looking down at her crotch, not much seemed different, aside from the fact that her pubic hair had become a dark, chestnut brown color instead of brunet. It actually almost looked like fur. It was that short, if not shorter, all the time anyways, so it didn't bother her too much.
Bending down further, Jen still couldn't see much, though she did notice that her pussy lips seemed... puffier, like she was incredibly aroused. Rummaging through her bag, Jen extracted a small hand mirror she used for applying makeup in the halls between classes. Opening it, she angled it so she could see her slit. Gasping, she stared at her changed twat. Instead of the normal soft, juicy cunt-lips that would generally greet her, she instead had a long, tear-drop shaped slit. When she pulled the lips apart, instead of the moist, pink flesh that was normally revealed, a great gaping hole of a pussy greeted her.
Getting over her initial shock, she studied it more, and suddenly remembered what it looked like.
"The curse is real..." Jen murmured. "I have a horse pussy... A mare pussy for fuck's sake!"
Pausing for a moment, and looking at the very real, very animalistic pussy that was now hers, she pondered her options.
"Hmm... Well, I supposed that since I have it... It can't hurt to try it, now can it?"
Setting her mirror down, Jen sat herself on the edge of the toilet, before reaching down with a hesitant hand, before gently rubbing her new, larger, clit. Shuddering at the increased sensations, Jen rubbed harder. No wonder horse didn't need to couple that long to get so much pleasure! This felt great!
Reaching down with her right hand as well, as her left continued to pinch and rub her clit, Jen plunged a few fingers into her expanded cunt. Her shuddering increased with the greater stimulation, but it still wasn't enough. Balling her right hand into a fist, she plunged that fist into her folds, elicting a cry of estacy. Soon, she was bucking uncontrollably as she masturbated with her new equipment. Suddenly, without all that much warning, a great orgasm rocked her, causing her to muffle a sudden cry at the intense pleasure.
Slumping as she came down from her high, she looked at the pussy-juice splattered floor in front of her, as well as her soaked hands.
