Thick MILF Riding Purple Toy in Passenger Seat

She knows exactly what she's doing to you. Her thick body sways gently in the passenger seat, her yellow floral dress hugging her curves as the car moves. She's got a blue fuzzy cover wrapped around the seatbelt across her chest, and a thin silver bracelet with a charm glints on her wrist.

She picks up that light purple vibrator, resting it on her lap near her thighs, and slowly starts to use it inside herself. Her facial expressions shift, mouth open, eyes looking forward or closing briefly, lips parted, cheeks flushed. She smiles faintly at times, and you can see her getting more into it by the second. Her body responds, her breathing changes, and you can almost hear the sounds she makes as she edges closer.

You're stroking along with her rhythm now, feeling your pulse quicken as she tips over the edge. She's still seated, holding the device, looking toward you with a slight smile as the car keeps moving outside. What happens next?
