A lone figure, Cgy2015's soloboy, explores the intense sensation of urethral insertion using a medical-grade syringe. With a steady hand, he fills the barrel with clear lubricant, positioning the tip at the entrance of his slit. He pushes the plunger, feeling the cool gel fill his urethra, stretching the delicate tissue. His cock twitches, reacting to the unusual sensation. He repeats the process, increasing the pressure, until he can't take it anymore. With a groan, he milks his engorged member, releasing a torrent of cum, mixed with the excess lubricant, in a satisfying bukkake finale.
