As the last customer leaves, young Matheus de Andrade Carvalho locks up the supermarket, his shift far from over. With a mischievous grin, he slips into the storeroom, unzipping his pants to reveal his throbbing erection. He strokes it eagerly, his precum glistening under the harsh fluorescent lights. The sound of his hand sliding up and down his shaft fills the empty store as he thinks about the day's customers, their eyes on him, wanting him. His body tenses as he feels the familiar surge of pleasure, his cock pulsing as he unleashes a torrent of cum onto the cold concrete floor, groaning loudly in the empty supermarket.
