Guy wearing shirt, tie and glasses gets totally covered in thick green slime. The sensation of being gunged, fully-clothed, combined with the knowledge that his humiliation is being recorded on cam, turns him on. It makes him aroused, his cock hard in his pants. He fondles himself. Plays with himself. And as the gunge rolls over his bald head, his plays with his erect cock. Eventually he drops his trousers and enthusiastically masturbates, both humiliated and excited, until he ejaculates into his briefs.
