Unexpectedly Pet

While searching his girfriend's room, Tom found an interesting cat's bell and decided to try it on just for fun, wondering why she had one of these things to begin with.

As strange sensations began to spread around his body, the scared boy tried to take the bell off... But it has already locked itself on his neck...

His cotton shirt shrunk and became tight, as if it was made of rubber.
His pants slowly dissappeared like leaves on autumn.
He yelped, and a strange voice he didn't recognize came out of him.

As the transformation complete, he (she?) looked down on himself (herself?).
His chest had sizeable breats, his waist was thin, and his ass was...
Well...
Those were all the features he wished a girl would have... But he wasn't one.
There was also a long tail comming from his behind, and every surface of his skin was covered in fur.

He wasn't a girl...
He wasn't a cat...

"Was she?", asked a voice in his head.

"You are", it said.

"No!", he screamed, with a high pithed voice, "I'm not... I'm a... I am..."

"A girly cat", said the voice...

"No...", he tried to remeber what he was... But it felt so distant...
"I am..."
"I am..."
"I am cute..."

"Yes you are"

A few minutes later, his girfriend finds herself a pet she wasn't expecting to play with...
