A solo masturbator pushes his limits, pissing and cumming repeatedly in a marathon session. His boner never wavers, each stream of piss and cum more intense than the last. He's a slave to his desires, his body arching with each release, the room filling with the scent of sex and urine. He's lost in his own world, hands-free, his body the only tool he needs to achieve multiple, satisfying climaxes.
