“Ahhhh!” Nicholas cried, his voice going up a couple of octaves. Sparks of painful bliss shot through his chest, causing his whole body to shake. He knew this was wrong, but the fumes from the water made it hard to do anything but give in. She’s changing me-- they’re using magic. What is happening to me? I-- I have to go…  He tried pulling away from Tia but found it more difficult than expected. His arms looked so small now, his hands small and lithe without hinting at the callouses he once had. No, no-- it couldn’t be… Was he turning into a girl? This was a complete nightmare.

“Look how sensitive you are! Don’t try to fight this, okay? Look how nice your legs are becoming,” Tia giggled, dipping a hand in her water.  

“This-- this isn’t right!” Nicholas pleaded as Tia’s hand brushed against his calf. She slid her hand up the entire length of his leg and then slowly rubbed up and down over his inner thigh. Not only was this arousing, but he felt how much his legs were changing. The first time her hand made a full round up and down his leg, he could feel his muscles. But, the longer she rubbed his leg, the softer and less musculature it seemed. Soon, her leg was even more sensitive. “H-- Hey! Stop…” Nicholas begged, squirming away. His thighs shouldn’t be so damn sensitive. To make things worse, he felt a ball of pressure forming below his navel while his hips contorted and pushed outward. 

“Ugghhh!” Nicholas groaned as his waist suddenly pulled inward. The pressure inside of him started to grow at an alarming rate while his beard stubble and body hair fell off of him and into the water. “I-- I need to fight this-- you’re insane…” He whined as his voice got higher. He felt his whole head and face tingle as his bones and cartilage popped and cracked. He kept shrinking while his squared, masculine features melted away. His physical resistance was futile; why couldn’t he fight!?

“New kittens are especially affected by catnip, you see. The oils in this water invoke a sense of euphoria and relaxation, nyaa~” Tia insisted. “‘I’m excited to have a new little sister.”

Sister? Catnip? What?-- No-- no, no! He panicked, trying to stand up. As he did so, he felt the weight of his new hips. He felt the pronounced curve of his back leading all the way to an ass that was much perkier than it had been minutes ago.

“Shhhh… You’re small enough for me to do this now,” Tia flashed a devilish smile as she grabbed Nicholas. “Come down into the water with me, sweet kitten,” she purred.

Nicholas was too weak to fight as Tia pulled him onto her lap and held him from behind. He felt her hands slide all over his body, touching his abdomen, chest, legs, and hips. His changing body was so damn sensitive. As Tia touched every inch of him, his body’s new curves and shape became more apparent. “I-- I am not a kitten!” He squeaked in protest, his voice sounding more feminine than masculine.
