These guys solely live for the sake of producing milk for D-Corp. They care for nothing else except for the pleasure they gain from their cocks being constantly milked. Each spurt, each drip, even each twitch, from their cocks, is orgasmic bliss. Then there are robotic arm extensions that periodically administer nutrients and aphrodisiacs. They also help massage and tease them when needed. Everything is provided for them; these men truly love their job. Thank you D-Corp!
