Panties stretched tight around thick cockhead, stranger thrusts into fabric barrier while bus rocks with passengers nearby, her thighs clench to hide the bulge. Pink pussy lips peek out slick and swollen, gripping the shaft base as he grinds deeper with hands on her hips. Almost caught vibe spikes when she glances back nervously, yet she pushes ass into him harder amid the crowd. Random guy unloads ropes of cum soaking through panties, warm seed seeps onto skin while she bites lip to stay silent. Bus seats creak under shifting weight, strangers oblivious to the filthy creampie happening inches away. She adjusts skirt quick, cum trail glistening down leg before anyone notices the mess.
