Lost in thought, she discovers her panties damp with arousal. The cool air against her skin sends shivers down her spine, her nipples hardening. She slides her hand inside her panties, finding her clit, circling it with a practiced touch. Her hips move in rhythm, her body yearning for more. She pulls her panties aside, baring herself, her fingers delving deeper, mimicking the thrusts she craves, until she's writhing, her breath coming in gasps, her body convulsing in silent ecstasy.
