In a kinky experiment, a smooth, young twink pees directly into a Ziploc bag, capturing every last drop of his clear, sparkling piss. He seals it tightly, then brings it to his mouth, licking and sucking the bag, savoring the salty taste of his own essence. He then presses the bag against his hard dick, jerking off furiously, the cool, wet plastic sending shivers down his spine as he edges closer to release.
