Hidden behind a flimsy wall, a stranger's cock awaits, throbbing with need. A soft, warm mouth envelops it, sucking gently, then hungrily, their tongue tracing the veins, teasing the slit. The recipient leans into the pleasure, their body tensing as they approach climax. The mysterious giver continues, their pace steady, their goal clear. The room fills with the sounds of wet slurping and muffled moans, a symphony of anonymous lust.
