Justin focused through the pleasurable sensation of the slippery pig-skin against his body. He knew that he mustn't give in to them, or he'd fail the exam, and he might even be trapped in a pig-boy form if he was expelled afterward. Desperately, he tried to think of a form that could win out against the mental will of the pig-boys. Just as his snout began to take form and his tail began to sprout, he thought of the perfect thing.
"No! Enough!" Justin screamed with renewed willpower as he took control of his transformation. The pig-boys hesitated as Justin doubled in size in one enraged burst. The clothes that the pig-boys hadn't already torn off of Justin fell to the floor in tatters. Justin's skin toughened, and his snout morphed and re-formed into a long muzzle. His tail straightened and grew long, thick fur to match the color of his hair.
