Sam rushed into the first bathroom he came to, not noticing that it wasn't a mens' room. He was barely two steps in before he came face to face with Tiffany Slade.
Tiffany Slade was a freshman, a petite little brunette with quite small breasts. She was only 5'3", and weighed in at an almost nonexistent 95 pounds. Today, her medium-length brown hair was pulled up in pigtails, and she was wearing a short skirt and a white button down shirt, much like a Catholic schoolgirl outfit. Her brown eyes widened as she saw Sam. She opened her mouth to scream, but Sam quickly clasped a hand over it. Her hall pass fluttered to the floor.
"Transform or dare!" Sam hissed in her ear. Tiffany tried to respond, but couldn't; her mouth was still covered by Sam's rough hand. "No response, then you get both!" He said gleefully, "I dare you to do whatever I tell you to do. Transform into a shewolf whenever I change, with the duration lasting two hours until you revert to human form." Sam smiled at her,"Don't scream." He said, uncovering her mouth. Tiffany just stood there, staring blankly at him. "Now, use transform or dare on me, and make my duration two hours as well."
"Transform or dare," Tiffany said, almost robotically. Moments later, Sam's duration matched his new slave's.
"Now," Sam said, feeling his wolfish side coming out as his arousal grew, "Drop your panties and lean up against the sink countertop." Tiffany complied without complaint, much to Sam's delight. His eyes began to glow as his wolfish side pushed further out. He could see his wish had come true, as Tiffany's ears had begun to twist and point upwards as well.
Sam pulled his cock out, sliding it in Tiffany's slit, slamming into her roughly, growing rougher with each thrust as the two of them changed, watching it in the mirror.
Their clothing began to rip as their bodies changed and contorted. A few minutes later, and they were no longer recognizable as students, rather as hulking, howling beasts, a pile of tattered clothing the only evidence of their transition from human to beast.
"Now," said the Sam-wolf, in the language of the werewolf to his new slave-mate, "We infect the school."
