Tied and squeezed!

I fixed his hands, then tie his cock hard and tight.he can not come so, I know that! I blow his cock, cum, suck more and more intense until he is hypersensitive.he can not cum, can not stand it anymore but I have no mercy and continue until he whines.then I jerk him hard and fast and hit his balls! he is totally finished and I just let him lie with the tied cock!
