Jimmy figured the normal fire alarms would have some sort of invisible ink on them or something, so he ducked into the chemistry lab. The chem class was in lunch right now, so he was the only one there. He poked around for a minute, found the alarm, and pulled it.
Jimmy quickly stepped back into the hallway and started towards the nearest class he could see, the Trig class. They were all in his grade, so he didn't look horribly out of place, but someone would see him eventually. Better make sure that doesn't happen.
Jimmy turned towards another student. He saw some nerdy guy he didn't remember the name of. He'd do. Jimmy imagined him changing, and just like that he fell onto his hands. Almost as fast as he imagined it (Jimmy was getting good at this), his fur grew out, and his tail began to rip out of his pants. "Wh-what the fuc-" was all he managed before his muzzle extended too far for him to talk. Looking down, you see he has a pretty big boner. Maybe he did want this after all.
The change was almost done, with the guy as a very nice looking wolf. The rest of the class was so concentrated on leaving the building only one girl, Caroline Johnson something-or-other, had noticed anything. "It's like the're just coming to me," Jimmy noticed. No need for discretion this time. He forced her onto four legs almost instantly,repositioning her hips so her pants fell off immediately, unlike the other guy, who still had his torn clothing on. Her face hadn't changed yet, so she could still talk, but her ass was most definitely not human.
Exactly as Jimmy had hoped, the male began too sniff the air, catching the scent of a female in heat. He quickly noticed the new she-wolf, and began to go down on her. Caroline started to yell, but her face quickly changed, leaving a girl in a wolf's body being fucked. Her sanity wouldn't last five minutes.
They both came at the same time, spraying sexual juice everywhere. Jimmy had already walked away. Caroline would be a sex toy for the wolf for the rest of her life. Jimmy ran through the mostly empty halls, knowing he would very shortly need a pretty good excuse to shift the blame for this. However, he knew the answer to this question before he even finished asking it, running into a hallway full of students. He got an idea...
