The curse spread like wildfire throughout the school, the girls that were on the bus all had similar experiences to Jens in their own classrooms. They saw their teacher or another student that riled their beast to life and they couldn't contain themselves. Some incidents were more contained where the girl tried to hide her cock and a little bit of cum escaped onto another girl, just like Jennifer's case. But for the most part the girls couldn't handle the immense pressure of their growing desires. Their huge horsecocks sprang to life tearing through their clothes and bursting into the view of the class, and then the girls couldn't help themselves, they started to stroke their huge throbbing members and finger their quivering horse pussies. The classes were shocked and frightened as this girl they thought they all knew just whipped out a horsecock and started masturbating. It didn't take long for their huge amounts of cum to start churning in their horse testicles. The girls screamed out in pleasure as cum rose up their shafts and gushed out of their monster of a horsecock, showering the class with hot sticky seed.
As cum rained down onto the unsuspecting girls of the class their own changes began. They all felt a burning in their crotches as the curse took hold. The untransformed girls were all in a state of intense pleasure but also horrified to what was happening to them. Moans could be heard throughout the rooms as a bulge started to push against their panties. The girls yelped as their growing horsecocks burst through their restraints tearing whatever was in its way. The pleasurable heat continued as their pussies and ass began to change as well. Their pussies becoming a jet black mares cunt, and their asses puffing out into a jet black horses anus. Their huge testicles dropping into their newly formed sack and begin to brew a huge amount of cum. The girls cocks continue to grow immensely into a monster of a horsecock ranging from 2 to 3ft and a variety of colors. Cum churns in their balls as their beast reaches its full potential. Horror passes as pleasure takes over and the girls are compelled to stroke their new pillar of a horsecock. Cum fires up their shafts with a fury of a volcano as the girls scream with their most powerful orgasm of their life, cum explodes out of their cocks and gushes all over the classrooms covering everyone. As their cocks were raining down cum upon the class their horse pussies squirted girlcum covering their balls and horse ass and started to run down their legs. The boys have no idea what is going on and are horrified when cum is slathered all over them from the new addition of horsecocks that just sprang out of every girl in the class. However after getting turned on from the sheer amount of pleasure the girls were having they joined in on adding their seed to the mix. The girls were in a haze of fascination for their new horsecocks and continued to drive themselves to completion over and over again.
The classrooms of the infected girls were all covered in cum along with everyone in them. Yet these were only a few classrooms of the school that had changed. But then the bell rang to switch classes it was all over. Everyone filed into the halls where the the curse spread like a super virus. Every female in the school started to get the curse and they all grew their own ginormous horsecock complete with a horse pussy and ass. The entire school was filled with the sound of pleasure as the female students and teachers got accommodated with their new additions. The whole school was covered in cum and no one had any idea how or why this happened. The school ended up closing for the day sending all the students home. The girls all wandered home trying to cover their horsecocks as best they could. They all got off their cum filled buses unknowingly about to infect any female members of their family.Jen and Katie sat next to each other on the bus ride home discussing the insane day.
