Drive-by stripping!

As she ran, Kaitlyn was aware of the back of her towel billowing behind her, likely showing a lot of leg, if not more. Her backpack helped to keep her towel pressed against her, but it ended his above her bubble butt. Her towel ending just a few inches beyond the bottom curve of her bodacious booty. The towel separated in the front with each step, teasing a glance of the treasure between her legs, but never giving anything away.

Finally, Sarah had to wait at a traffic light to change so they could cross. However, as Kaitlyn stood on the corner waiting, she should have stood a bit further away from the curb, as a car that had been slowly following her had now caught up. The passengers had seen the hint of bare inner thigh as they followed and wanted to know if their suspicions were true. As they sped around the corner, the front passenger reached out and grabbed a handful of Kaitlyn's towel.

The **** of the car pulling the arm, which pulled the towel was enough to uncouple the knot she had tied! In an instant, Kaitlyn's towel opened and and was nearly pulled off, but thanks to her backpack, it remained on her body, but her entire right side had been exposed.

The passengers inside whooped as Kaitlyn's right breast was uncovered, but as the towel remained behind, they groaned at the failure to procure her garment.

However, the one who was the most disappointed was Sarah, who had let Kaitlyn stand in front of her, so she only saw the events transpire from behind, missing out on her exposure completely.

However, once Kaitlyn got her towel back on securely, it was time for them to cross, and then walk a few more blocks to school.
