In the street

The clock rings, but you don't wake up. Two hours later, you wake up realizing that you're late for work. Yuo quickly dress a tight dress that you left there close to your bed, not using underwear. You grab work stuff and you go running to the bus stop. There, a few cars pass, and huge truck. The truck pass close to you and without you noticing, one pointy part of the truck hook your dress, and for the velocity of the truck, the dress rips off. You hear a huge "RIIIIPPPP", and then, a cold breeze, and then everybody looks at you. You finally look down, only to see your erect nipples and your hairy pussy. YOU'RE NAKED IN PUBLIC!!! What do you do: cover with your purse or you just call help?
