The bathrooms!

You make a sprint towards the bathrooms, swinging open the doors of the woman's side and stumbling through it. You look around quickly to make sure you're alone, but you're not.

Ahead of you is your friend Alison. She's a long-haired blonde with a pair of denim shorts and a pink tank top. You're relieved to know it's at least a friend of yours, but you're standing in front of her with no pants on! You continue to cover yourself, looking out frantically, just waiting for the door to open... But you can't move even a few more steps right now. Not with these panties.

Alison raises an eyebrow at your situation. "... Are you alright?"

You shake your head, explaining your situation desperately. She curls her lips into a much-too-big smile.

"Naughty... I bet you planned all this. You wanted all those people to see you, didn't you?"

You shake your head again. That's not what happened!

"Mhm," she purrs. "Of course not. Well, I'll help you out. Why are you so worried anyway? People change in the bathrooms all the time."

She's not wrong. Though you aren't used to wearing such a revealing bottom in public. When you dress for the beach, you at least are somewhat more covered than this... Additionally, you usually aren't moaning with every movement of your legs. You stop self-consciously covering your underwear anyway, nodding, thanking her for her help.

"I heard Troy and Roger are at the beach anyway. There's a lot of nice guys there too," she says with a wink. "Luckily for you, I always pack an extra bathing suit. But you're going to have to pay me back. I even have a way of how you can."

You smile, accepting her offer. She begins to dig around in her bag. "Come on now, Jane. Take off your clothes. Don't worry. I'll be doing it too."

You reluctantly slip out of your panties, and then your shirt, and lastly you unclip your bra. She happily takes them from you, putting them into her bag as she pulls out two bathing suits. They don't appear too revealing. In fact, they're both nearly the same, though she hands you a red one while she takes her pink.

"Now... The payment part," she whispers, suddenly sliding something between your legs. You yelp, trying to escape, but she holds you tight. The feeling soon subsides, though as she pulls back up, you can still feel something in there... You look puzzled.

"Trust me. It'll be better than going out there naked. Or, you can take it out, and I can leave right now, with all your clothes."

Your eyes widen and you accept whatever her twisted game is.

"Good." She puts her bag down and slips out of her own short shorts, revealing her thin pair of pink undies. She pulls them off as well, followed by her tank top, and then her bra to match. You try not to eye her naked body over, as it's a little embarrassing given your situation.

Thankfully, she hands you the red two-piece while she slips on the pink one. You put it on, testing it around. It's definitely too tight. Clearly Alison has a much smaller chest and general physique than you, but it's definitely an upgrade from earlier. You feel concealed enough to be confident again, thanking her again.

"Not a problem~! Now, let's go see the boys. I think it'll be fun."
