Restrained sub humbled for intense cock milking ruined 4 times in a row

My chastity sub is naked on all fours with his ass in the air, ankles restrained to either side and wrists shackled to the other end.of the bondage table. His balls have a steel ball weight and a humbler chained up above him to keep his ass in the air and his balls out of the way for a good milking.To begin with I plug his ass and then I use my fleshlight to get him hard and use my hands to softly edge his cock. After I get him to the first ruin, they come quickly one after another, each one more frustrating than the last. 4 ruined orgasms in a row with the man muck firing all over the table. After the 4th he's super sensitive and can't take anymore so I call it a job well done and write a nice message on his ass to remind him that he got OWNED!.
