They head for the first ride

Sofia gasped as she felt a sudden snap, the seams of her sundress giving way with a sharp rip. She looked down just in time to see the fabric split open across her chest, buttons flying, leaving her suddenly and shockingly exposed. Her hands flew up instinctively, face flushed. “Oh my god, Leonor!”

But her sister was already laughing, breathy and carefree, her Bimbo Beer long gone and her Exhibition-Bits doing exactly what they promised. Leonor had slipped her dress almost completely off one shoulder now, showing far more skin than Sofia had ever seen her casually reveal in public. “Babeeee, just go with it,” she giggled, tossing her hair and licking a bit of sauce from the corner of her lips. “You look so hot right now!”

A group of guys nearby let out a cheer, clearly having caught the moment. One of them whistled, another shouted, “Park of Pleasure strikes again!” and suddenly the sisters were the centre of attention, with Leonor soaking it up like sunshine. She grabbed Sofia’s hand, tugging her up from the bench with surprising enthusiasm.

“Come on, we’re totally riding The Nipple Fucker,” Leonor chirped, bouncing slightly as she led the way towards a coaster in the distance. Her hips swayed, dress barely hanging on, and she made no move to adjust it. Sofia stumbled after her, still stunned, one arm trying in vain to hold her busted dress together, but the tingling warmth from the fries was still spreading, and deep down, something inside her was starting to let go, just a little, especially as she felt good about the guys's attention for some reason and also because she caught some peaks of her sister's pussy between Leonor's legs as she not cared that her dress had slipped up.
