Ruined orgasm at the milking table

Giving my friend a ruined orgasm under the milking table. I unlocked him from chastity, so he can get some relief. But I didn't want to spoil him, se he wasn't allowed to see me (he was blindfolded on the table) and his orgasm had to be ruined. After long denial all he could do was to lie on top and listen to his cum splashing on the floor.
