How do you "accidentally" wear someone else's underwear? Did you accidentally fall through the leg holes and accidentally pull up it up?

"Oh no! These are cotton panties! I wear lacy lingerie! My reputation is over!"

If you set out to make your classmates very confused about their sexualities, mission accomplished.

One thong is like another?

Definitely need a follow up on this one. Unless there's something fishy going on between you and your sister.

How accidentally was this?

Hopefully it wasn't stretched out to much in the crotch for you.

I have just one question: HOW?!?

I really appreciate the cleverness of the title

"Accidently"? Ok. Doesn't female underwear lack the roominess of male underwear in certain places to realise it was the wrong one? Also move away from tighty whities to boxer briefs. .
