Tease him.

You wrap your fingers around the strings of your bikini top, and slowly bounce them up and down. You watch as his eyes follow your breasts movement's perfectly. You explain to him that you really really need some clothes. Even a wrong movement could pop your tits right out of your top...

He seems absolutely mesmerized, and when you look down, his trousers are barely containing a rock hard cock. You have him right where you want him. You ask him again.

"I--... I d-don't know..."

You bend over slightly, cradling your cleavage directly in front of his face. You ask once more.

"Uhm... Okay! Okay! Take a few pieces, but please bring them back as soon as you can. My niece will be so angry..."

You smile and approach the line. You remove a pair of black pants that look like they'll fit well enough, as well as a black t-shirt. Hoping you can do it without a wardrobe malfunction, you slip the pants up your legs and to your waste before unbuckling the skirt. You place the skirt away in your bag, and you slide the shirt up over your head, allowing the barely-a-bikini to fall loosely to the grass.

You look yourself over. The pants seem to be skin tight, clearly yoga pants, and the shirt fits alright. They're both slightly too small, but a huge upgrade to before. You thank the old man and head on your way. You have no panties or a bra, but you feel more covered than you have all day. Things are finally looking up today!
