Thick thighs splayed across the red bus seat, her fingers dig into her pussy as she grinds against nothing but air. Back bows off the cushion, belly trembling with each desperate stroke, her other hand clutching the seat edge like it’s the only thing keeping her from flying apart. The bus hums around her, headlights flickering past the windows, but all she cares about is the wet sounds filling the aisle. Curvy hips lift off the seat, thighs shaking, as she bites down on her lip to stifle the moan threatening to escape. One hand stays buried between her legs while the other reaches up to grip her own tits, squeezing until her breath comes in ragged gasps.
