My chastity sub is ready for a milking so I get him naked and on his knees in the living room. His balls are chained up to his waist chain keeping them out of the way to make the almost orgasms more intense. I proceed to milk his cock with a handjob from behind and slowly edge his cock until the cum is ready to flow and then I stop at the perfect moment to ruin the orgasm while squeezing his balls while the cum dribbles out. After the first ruin it doesn't take long for 3 more ruined orgasms to follow in fairly quick succession. One after another, I slap his cock around, tease his frenulum and use slow strokes to frustrate his throbbing cock and empty his balls while ruining his orgasm.
