In the gritty streets of Berlin, a 16-year-old amateur, under the mentorship of Prollking, explores his fetish for massive cocks and enlarging his own. Wearing sportswear and sneakers, he starts with a 16cm cock, working it with his hands and the pump, feeling it grow and stretch. His foreskin plays peekaboo with his glistening, engorged head as he nears climax, finally releasing a huge, thick load that dribbles down his shaft and onto his socks.
