Silver hair tucked behind her ears, the older woman grips the edge of her seat with one hand while the other disappears under her skirt. Her thighs tremble as she rocks her hips, fingers moving in quick circles. The car’s interior lights cast a soft glow on her flushed cheeks as she bites down on her lower lip, breath coming in short gasps. Every squeeze of her thighs tightens her skirt against her thighs, the fabric straining with each pulse of her fingers. She leans her head back against the headrest, eyes squeezed shut, lost in the raw sensation of her own touch.
