Advanced magic

Samantha should have paid more attention in her magical studies class. They warn of flipping ahead and casting spells that are too advanced. Sam figured she knew what she was doing and decided to cast a transference spell with her cat. She figured it would be fun to be a cat for a few hours. The only thing was the spell required her to cast a nullification spell first set for time she wanted to swap back, but she went right into casting the transferance spell. She found herself on all fours and she loved it. Not having to worry about her human life and the stress that came with it. She could just sleep and eat and lay around the house. When she got bored of it, she went into her room and saw her body playing with her boobs. The cat apparently was enjoying being human. That was when Sam found out that she couldn’t swap back and that she skipped over a step. Turns out without the nullification spell she could only swap back if both parties agreed to the swap and Shadow loved being a human and did not want to swap back. So Samantha was doomed to remain a cat forever or until Shadow got board and wanted to return.
