She finds some relief

This whole experience has been sexually overwhelming for Leigh, and she can't wait any longer. She practically runs into the open dressing room, throws the curtain shut, and settles back on the bench, legs spread. Without hesitation she starts rubbing her soaked pussy. She has never been more turned on in her life.

She pulls her shirt up, freeing her tits so she can rub and squeeze them with her other hand. She rubs her clit in circles, then plunges two fingers into her cunt, fucking herself with abandon in the dressing room. She alternates between fingering and clit play, building herself toward orgasm.

She watches under the curtain as people walk by. She can hear conversations and laughter. Just feet away, with only a canvas sheet between them, hundreds of people are going about their day, completely unaware of the slut masturbating nearby. Leigh shudders. It's so hot.

Then she realizes--not everyone is totally unaware of her sluttiness. She remembers the man staring at her chest. She remembers the two girls who saw a clear shot of her pussy. One was disgusted, and the other was interested, and somehow both of those turn her on. Knowing that strangers saw her makes this even hotter.

Soon, Leigh is reaching the edge. She starts to moan and immediately claps a hand over her mouth, stifling her sounds. She rocks her hips on the bench, riding her hand as she pushes herself to orgasm. She cums with a shiver through her whole body, silently screaming, and she can feel her wetness dripping down onto the wooden bench.
