Unlocked from chastity to be edged and denied

I restrain Rod's ankles and wrists to the milking chair and blindfold him. Once he is restrained I unlock his chastity cage so I have access to his cock ready to have a play. I edge his cock over and over ensuring he doesn't go too far by always stopping just before he blows and give his cock a good slap then leave it to calm down before starting again. He didn't get to cum I just wanted him to think he might do.
