Chloe and Sergio, clad in lab coats, conduct a 'cumshot' experiment in the name of science. Sergio, the latino lab assistant, strokes his massive cock, building up a hefty load. Chloe, the curious scientist, guides him, jacking him off as his cock grows harder, veins bulging. The room fills with Sergio's moans, his breathing ragged as he nears climax. With a final stroke, he unleashes a torrent of cum, painting Chloe's face and tits, completing their 'cumshot' study.
