As John is looking into the mirror, seeing how odd he looks, he notices his clothing becoming shiny. "What in the ... Meow!?" He watches as his black pants turn into slick latex, and then shrink into a pair of skin tight shorts. His cock is plainly visible through the stretchy material.
His shirt on the other hand, turns black, and then turns into latex also. But instead of shrinking, it developes holes. The holes grow bigger, and his shirts turns into a skin tight latex harness, which is attached to his collar.
Nobody could possibly mistake him for anything normal now. He looks like some rubber fetishist wet dream.
Almost as is to prove him wrong, the bathroom door suddenly opens and somebody runs in. They pass by John, almost ignoring him. They quickly use the urinal, wash their hands, and then nod at John as they walk out. He watches several other people, use the bathroom, and they only seem to look at him oddly because he is just standing there watching them.
