He hangs there lightly, almost weightlessly, like a wet sack. The slave pig. Rigidly fixed by his arms and legs, spread wide, his ass out, his cock rock hard. The smacking of the milking machine and the gentle rocking drive the horny sack almost into the nirvana of horniness. It pumps, it sucks, the vacuum of the Venus 2000 draws the **** from his head. Can he think clearly? None. That's how the Mistress likes it. The shaft throbs, the Mistress laughs and holds the smacking, greedy device in place. The stupid sow is milked like a cow. He swings and rocks in his harness, he moans and sighs. Not out of desire, no, because he has to. There is no escape, only sucking and laughter from the Mistress. His cock is already overstimulated and sore. And then finally the liberating command. The hard emptying, a painful orgasm, and his final twitch. Shot empty and left hanging. It's just not a bed of roses. The rubber slave's life.
