Quickly, Jen's enhanced horsecock herm flu spread through the school, as men first turned to women; to the women, breasts grew and filled with milk; hair got longer, silkier, and more perfect; hips expanded and asses grew; horse ears replaced their normal ones; bushy horsey tails grew; and finally, normal genitalia was replaced with horse pussies, assholes, and cocks.
Mental changes quickly took hold as their scents changed to a sexy, horsey musk, capable of arousing both humans and horse herms. Most of them forgot their old lives immediately, and the ones that didn't were still happily taken over by lust as their minds slowly faded away. Jennifer and Kylie were the only ones who still remembered the old world; Kylie had been taken over by lust and obedience for Jennifer, and Jennifer didn't really feel any regrets. She continually orgasmed throughout the day, and as her huge cock spouted corrupting horse-herm cum. The newly transformed herms, in fact, seemed especially attracted to Jennifer, and she had her own little harem of fucktoys by the end of the day.
"Oohhh it feels sooooo goooood!" Jennifer cried out, as her harem of horse herms pleasured her. One of them kept sucking the milk out of her gigantic breasts, another alternating between her cock, balls, and pussy, and the last pleasing her ass. Jennifer suddenly came as the bell rang and noticed that every single horse herm in the school came. "Interesting... I guess it really does effect reality."
Satisfied, Jennifer went home, her corrupted mind eager to see her family.
