It's my human pet's turn for the night shift. He's wearing my collar, waiting for me in the stall behind the milking station. Just thinking of him kneeling there naked, cock hard, a mix of anticipation and fear, makes my nipples stiffen. I need to go 'inspect' his obedience first, 'soothe' him properly with my toys until he comes in my hand, or on my face... Only then can I take him to show him off to the new heifers. A good pet deserves his owner's rewards, don't you think?
