A dominant voice sets the rules: "Get naked, fuck your ass, and cum in 10 minutes." The eager amateur strips, lubes up, and fingers his asshole, moaning as he works it open. He strokes his rock-hard cock, the clock ticking down. With just minutes left, he plunges a dildo deep into his ass, fucking himself hard as he jerks off. The challenge complete, he strokes out a massive cumshot, panting and satisfied.
