Both?

Panicking for a moment, Melissa spins around, trying to figure out what exactly just happened...coincidentally, giving both the bus driver, and the riders in the first few seats a great view of her ass through the windows.

Feeling around, she quickly finds the skirt... hanging off the pole like a very short flag. and begins tugging, causing her butt to jiggle slightly, and after a few seconds, the skirt comes loose with a small tearing sound, a sound that's quite worrying to the exposed redhead...

"Miss, I have to leave, please get on now or wait for the next bus," says the bus driver, having watched the whole show Melissa put on, and sees her going to try to put the skirt on, interrupting her.

Melissa freezes... she couldn't possibly miss this bus, not with how bad the wind is today; she might end up flashing the road for another hour if she doesn't get on, and so, making a quick decision, she climbs onto the bus, clutching her skirt in her hand, hoping that her shirt is doing enough to hide her bottomless state... unaware that Mary made sure that was not possible earlier when she rolled the shirt up.

Red-faced, lower lips open with clear signs of arousal, moisture leaking down her thighs... Melissa finds herself suddenly grabbing onto a hanging strap on the bus as it lurches forward, leaving her standing, unable to find a seat in her nearly blind state, praying that no one can tell that she is bottomless, unaware that not a single inch of her lower half is hidden.
