Jessica reaches her limit

It was too much. Poor Jessica's bladder was too full, her bare pussy exposed beneath her skirt, the cold metal seat sending chills through her body.

She regrets not using the toilet- or at least finding some underwear to shelter her pussy against the cold. Try as she might, the incontinent girl's floodgates opened, and wouldn't seal shut-

Suddenly, Jessica gasps as a single trickle of pee escapes her tingling pussy, a hissing sound emanating from the poor girl's seat as the trickle gives way to a flood, her quivering pee hole forcing itself open from being strained beyond its limit.

The sound of her warm piss stream spraying the metal seat was loud enough to attract the attention of the classroom around her, her ears catching distant whispers students snickering around her. Even Ms. Haythers stops what she's doing, pausing lecture to check on her, though Jessica was far too embarrassed to pay attention.

Eventually, the stream dies down to the final spurts, her skirt soaked at the back where she'd sat and at the front where she'd held her crotch, her pussy soaked with fresh piss as she curses herself for thinking she could hold it.
