Leo, left alone with his girlfriend's tanga, can't resist the temptation. He slips it over his hard cock, the fabric tight and warm. With each stroke, he pictures her in it, her ass cheeks bouncing, her moans echoing. His hand moves faster, his breaths coming in short gasps. The tanga fills with his cum, and he collapses, spent, the tanga sticky and used, a testament to his solo indulgence.
