Nothing quite like trying to remain relatively still in your seat while a transformation is kicking in. Glancing around nervously as your ears become more and more conspicuous, peeking underneath the table/desi to see your shoes fill to bursting, squirming as fur or scales or whatever covering brushes against your clothes, feeling your ass shift against the seat, or is it your hips, or wait, are you getting curvier? Maybe the seat has edges on either side, maybe a solid back, for your tail to overcome here in a bit when it decides to grow.
Are you in class? At a restaurant? At work? In a meeting? Wherever you are, you’re changing when you shouldn’t be, and it’s impossible to hide.
