Public Masturbation Leads to a Messy Orgasm

She finds a semi-secluded spot but it's definitely still a public area. Starts slow, just rubbing over her shorts, then slips her hand inside. You can see her getting wet, fingers working her clit in tight circles. She's trying to keep quiet but her breathing gets heavier. Picks up the pace, hips bucking against her own hand until she tenses up and cums. A quick, risky public masturbation scene that ends with her trying to catch her breath and straighten her clothes, looking around to see if anyone noticed.
