Emrinde mahvoldu - mahvolmuş orgazm

My horny slave wants to cum.. But I won't let him yet.. I very slowly tease and edge him to remind him his place, and that he's not allowed to ever have a 'real' orgasm.. After repeatedly being edged, he just can't take it any more and bursts right when I mention how close he is.. Poor slave knows that is all he gets so he stays horny and frustrated for me..
