Ruined Handjob in Latex Gloves Restrained by the Balls

My sub is blindfolded stood naked with his wrists restrained behind his back to the bed post and his balls chained to a heavy weight between his legs. I put on my latex gloves and proceed to edge, stroke and tease his cock until it's time for him to cum and then I stop any stimulation to ruin his orgasm. I slap his cock and then catch his cum in my hands for later.
