Katie makes for an alley to relieve herself, but she is discovered again...

Katie could barely keep her boobs under control. Not only were they painful to run with lacking a sports bra, but they were also struggling to fly out of the bra altogether. Surrounded by hundreds of men and women of all ages along with the audience watching from the sides of the race, she kept her hands glued to her breasts. Her boobs were not her only problem however, as her lace panties were quickly riding up into her crotch, creating an obvious cameltoe (which thankfully would be difficult to see considering she was surrounded by a host of other runners. Her panty issues continued on back though, with the thin material falling between her marble cheeks. What little the panties covered before was now being completely exposed, with probably about 60% of her butt already on display, with more being revealed every second. Beyond all of those issues was a compounding one with her bladder begging to be released. Katie knew that it was normal for runners to take quick breaks and even have accidents, but her panties were not made to be peed through. The lace material would stick to her skin and be essentially see-through! Hot breath choked her, but through the moving bodies around her, she spotted a number of tall buildings off to her right. She decided to just take a quick bathroom break before getting back out into the marathon. Maybe she could even find a way to get better clothes. Fighting her way through the crowd, she managed to get free. A few people gave her sidelong looks, the guys especially checking out her lower half. Ignoring them, she ran over to a isolated alley. Getting inside the narrow tunnel, she was disappointed to see that there was little cover, only being a couple dumpster to hide between while relieving herself. Making her way over, she found the dumpster closer together than she expected. Pushing them apart, she felt her panties and bra snag a bit, but she made sure to carefully unhook them (or did she?) before sliding her panties down and squatting.

Only Katie wasn't quite free just yet, as right after she started, she heard footsteps approaching from just a few feet away. She had to act now!

Who finds Katie?

• Could be a news crew looking to interview a runner

• Maybe one of her family members checking on her

• Maybe a pervert who wants to watch Katie do her business

• Someone else?
