Liam Harding, a burly, bisexual step-dad, finds solace in the confines of a public toilet, his massive, uncut cock aching for release. He strokes his big dick, feeling the veins pulse beneath his fingers, his foreskin sliding over his sensitive head. The tight space, the scent of sex and soap, drives him wild. He imagines his stepson's eyes on him, his own hand replaced by the boy's eager, young one. Liam's body convulses, and with a guttural groan, he nuts a huge load, his thick, creamy cum painting the stall, a testament to his bisexual desires.
