Robotics

You show up to your elective robotics class. You introduce yourself and explain your lack of wardrobe. The teacher seems to understand. Especially because you used your backpack as a chest shield, selling the idea that this was a freak accident and you're tying your best to cover. Your first lesson is in soldering. Oh, perfect! You actually already know how to solder and that's how you know you can pull this off. You wait until someone sitting near you makes a sudden movement and you drip solder all over your pants and the soldering iron in your lap. It gets hot and starts smoking but you're not in any real danger yet. As hoped, the teacher panics and pulls down your pants to save you. In his haste, he also pulls down your panties and for a few seconds you pretend not to notice to give the class a good look at your naked bikini zone, front and back.

You then pretend to just notice "Oh my God , why are you stripping me naked, sir! You're humiliating me!"

The teacher blushes profusely and stammers "I'm s-s-s-sorry! I-I didn't mean t-to!"

You cover your ass and pussy with your hands. And demand your pants and panties back. The teacher says "I can give you the panties but I'm afraid I can't let you keep the pants. They have lead solder on them."

He nervously pulls your panties up for you and demands that you pull of the pants, which you do after pulling off your shoes and then putting them back on afterwards. The teacher has a hard time looking at you during class and you see some of the boys sneaking glances at you and talking amongst themselves. This worked out better than you hoped. Not only were you able to find a way to get rid of those troublesome pants while maintaining your "innocence", but you even got to put on an unexpected ass and beaver show. And the teacher gave you a note about the incident which is great, because this is becoming increasingly implausible and you're not sure how long other teachers will fall for your charade.

You've got two tiny pieces of clothing left and you would also like to ditch your shoes and socks somehow, if possible. You're doing great so far!
