The black panties, a stark contrast against his tanned skin, become his obsession. He fingers himself through the fabric, feeling the rough texture against his throbbing clit. His moans fill the room as he thrusts against his hand, his body tensing. Finally, with a cry, he cums, staining the black panties with his white, sticky seed. He pants, his body shuddering with the aftershocks of his intense solo pleasure.
