From time to time I milk my slaves to keep them attended and servile. It's most important that the slave must not enjoy his ejaculation; if I milk them, it could be very painful. today I put clamps on the slave's nipples and with some strips attached to the clamps I can make them very painful everytime I pull on them. I also lace a strip around his balls to make him unable to shoot out his cum. While I prepare that milking I spits into his mouth again and again. That makes him really horny but he is in my cruel hands. i then uses my milking machine on his cock. No man can resist this devilish vibrating machine. He must cum. I spits into his mouth while I massage his cock with the machine. The moaning from the slaves gets louder and faster, he is going to cum and so I tighten the grip of my leather gloved hand on his cock. i perfectly ruins his orgasm and there is no shoot out. The juice only flows out of his cock and drops into the slave's mouth. With a cruel smile I leaves the milked but frustrated slave on his own...
