You decide to stay still for the time being. After all, despite what you might have guessed, being Kristen's panties is endlessly fascinating. It feels like your face is constantly in her pussy, and you feel like you're continually hugging her ass, and if the excitement ever goes away, you're sure it hasn't yet. Actually, you don't know much about how the transformation gun works when you turn into an inanimate object: maybe you feel happier as an object when you're doing what you're meant to. It's a neat thought. Either way, you love being Kristen's panties. Each moment in the darkness between her legs is heavenly.
But it's not like nothing happens while Kristen stays seated during class. Every few minutes, Kristen shifts in her chair, which for you is an interesting feeling as some parts of you are pulled tighter and other parts become loose. You don't feel pain or anything negative when you stretch, so it's just intriguing for you as you wonder what Kristen must be doing or thinking at that moment. What you do find disorienting, however, is not controlling your own movements. When you first turned into Kristen's panties, you were so fascinated by being green and silk and so differently shaped than you had been as a person that being worn by Kristen felt more like a ride than anything. Now that you have more time to reflect on your experience, you find your inability to move by yourself to be just another tight connection between you and your wearer. When she moves her leg, you move. When she shifts, you shift with her. It's a wonderful experience.
Even though the class goes on for well over an hour, you're still thrilled you had the foresight to do this. Eventually Kristen's shifting becomes suddenly dramatic and you realize that class must be over, and she's standing up. So far today, being Kristen's panties has been an adventure, and you're excited to find out where she's taking you next.
