Kathryn notices the young man's eyes locked on his friend. With a smile, she steps towards Tim, Kevin following close.
"You like what you see, Tim?" The witch asks, looking the boy up and down.
"I just," Tim starts, "he's a, he has, it's just so," he trails off.
"Cute." The witch finishes his statement. Tim wasn't sure what he was going to say, but he realized that's exactly what he'd been thinking.
"Ya," Tim smiled a little, "he's so cute." The boy took a step towards Kevin. "I just want to pet him."
Kevin's tail twitched slightly at the comment, and Kathryn laughed a little, "what's stopping you?"
Tim lifts a hand to his friend's waiting head. He touches the cat boy's ear and then pulls back, still not sure if he's imagining things. He slowly lowers his fingers and rubs the triangular object, eliciting purrs from Kevin as he does.
Kathryn watches as Tim pets Kevin's ear. As Tim strokes, his own ear starts to twitch and move, migrating up his head. He laughs a little, starting to enjoy petting his friend. He reaches up with his other hand and strokes both of Kevin's ears. Tim feels a dull buzz in his head as he pets, the light headedness covering the movement of his once human ears to the top of his head, now two brown furred triangular cats ears.
Kevin nuzzles against Tim's chest, the smell of his head tickling Tim's nose, causing him to sneeze and push whiskers out of his face. Taking his friend into an embrace, Tim has a clear view down Kevin's back, straight to his excited tail.
Kathryn's voice floated into his fogging brain, "it's an adorable tail, isn't it?"
Tim nodded absent-mindedly, his back tingling as he did. Reaching down, he took hold of Kevin's tail, feeling the soft fur. Kevin nuzzled against Tim's chest, and a lump formed in the seat of Tim's pants. Another stroking of the tail and Tim's own growth was pushing against the seat of his pants sharply.
Kathryn walked up to Tim, placing a hand on his neck and petting softly, "that's it, enjoy yourself, my cat boy."
The words caused Tim to jump in shock, the flexing of his new back muscles pushed his tail through his pants. Tim looked back at the brown tail now attached to his back, then felt the ears growing out of his head.
"What," he mumbled, "what is this?"
"You're my second little cat boy," the witch laughs.
