Underwear as swimwear

[NoOnesOnion87]

Who among us has ever been invited to a cookout or a friend's party or a beach party and you hadn't planned on swimming, but then something or someone changed your mind, but the only problem was you weren't wearing swimwear and you didnt bring a swimsuit, and you ended up swimming in your underwear. I'm curious as to what anyone said, and women? Please tell us about it?!
