Diana, married but craving thrills, slips into a public restroom, her heart pounding with excitement. She pulls out her phone, browses something tantalizing, and her hand slides into her panties, fingers rubbing her wet slit. Just as she's losing herself in sensation, the door creaks open, and a woman walks in, catching Diana with her hand in her panties, her face flushed, and her socks still on. Embarrassed but aroused, Diana smiles, her secret now shared.
