Jen headed to her next class, her mind wandering in twelve directions simultaneously. Every person she saw seemed to drive her to another level of arousal. It didn't matter whether they were male or female, classmates or teachers, she found herself entertaining the thought of having her way with them. "Good LORD, girl," she thought to herself, "You really have to get a grip!"
She walked into class as the bell was ringing. It was science, a class she normally did quite well in, so she initially wasn't too concerned. She took her seat at the back of the third row, pulling out her textbook and awaiting the lesson from her teacher, Mr. Jackson.
"Okay, class," he began, "You'll recall that in our last lesson, we finished studying the earth, so now we'll move on to our nearest heavenly neighbor, the moon."
Jen began to sweat profusely, and her heartrate suddenly increased threefold. Her right arm moved against her will, her hand sliding underneath the waistband of her skirt. Jen fought against it. She couldn't give in to her urge, not here, not now!
She gripped her desk tightly with her left hand, tensing against the urge to masturbate. Her nipples stood at rigid attention, visible to anyone who might glance at her, as they practically poked through the fabric of her top.
Mr. Jackson continued, turning the lights off and turning on a slide projector. "The moon has sustained hundreds of meteorite hits over the millenia, causing its trademark craters."
Jen whimpered, then whispered, "Nooo," as the combined second instance of 'moon', combined with the large screen images proved too powerful for her to resist the curse any longer. Her crotch felt like it was on fire, and there was only one thing she could do to relieve the feeling inside herself. She knew she shouldn't, but it was too hard to resist.
She released her hold on the desk, lounging back in her chair, splaying her legs apart, letting her right hand find its way to her clit, massaging it frantically as she tore at her shirt with her left.
The change was less painful this time, Jen noticed as her feet tore through her shoes. "Holy shit, I'm changing!" Jen realized, her conscious mind catching up with what was going on, unlike her first change. Just as before, her breasts ballooned and extra sets blossomed beneath, as she grew covered in a lush coat of golden fur. Her human mind was swept away before her muzzle grew, but it had stayed longer, and when she reverted, she would remember a bit more.
But that was later, now the class was quite aware of her condition, and her particular aroma of a bitch in heat. Heads began to turn, some terrified, some terrifyingly aroused.....
