Ben after seeing how quick and painless the transformation was decides to volunteer. He knows that there's a 50% chance that he could end up female but that it wasn't likely to happen. Besides he was hoping to stay male as he had always harbored a slight crush on you, unknown to you. "I'll take it!" He says
"Very well then, come on up" Ms.Tomlin says
Ben feels his heart skip a beat when he realizes that Ms. Tomlin accepted his offer to volunteer and he'll get to be with you. He takes a deep breath, stands up and makes his way to the front of the class. You take your place next to Ms. Tomlin and turn to face the class.
"Now then, my dear boy, have you always had an interest in wolves?" she asked.
"Yes, I've always been interested in them." he said.
"I see, so I presume then that you are ready to undergo your transformation then?" Ms. Tomlin walks over to her desk and opens the bottom drawer. She pulls out a bottled potion that is black in color. She walks over and hands you the bottle. "Drink up then, my boy. Not all of it, though. Remember to save some for the rest of your classmates."
Ben takes the bottle and takes a swig of the potion, forcing himself to swallow the thick liquid, thinking it will all be worth it as soon as he gets to be with you. It tastes like black licorice and he has to wonder what exactly is in the concoction to make it taste that way. You set the bottle down on the desk and stumble backwards, not feeling well. Ben begins to feel itchy all over and begins to scratch furiously, The transformation was beginning.
He looks down at his arms as grey and black hairs growing in as his fingernails grow out into claws. He can feel his teeth growing out into fangs as his ears grow to points. Ben looks over to you smiling, clearly enjoying the transformation.
Ben hears a tearing sound and looks down as his feet stretch and transform into digitigrade paws. The seat of his jeans tears open as his waist reforms and a large, bushy tail grows out. Shucking off his pants Ben sees his cock and balls slowly retreat into his body as a sheath forms over them before they continue changing inside his new sheath. His body begins to make more dramatic reformations as he falls forward onto what are now his front paws. The rest of his clothes rip and tear as his body slowly finishes reforming. He shakes off the tattered remains as the last of the changes takes place, his face slowly pushing out into a lupine snout as he is now a fully formed, if slightly larger than average male wolf.
Ben isn't paying much attention to what else Ms.Tomlin is saying, too entranced by the scent of a female wolf in heat.
