Mia's cow has been on the milking bench for a long time. But that doesn't matter. Mia needs to get as much pre-cum out of it as possible. Mia knows that the cow is withholding. She knows it has more inside. Mia needs to get it all out. Everything. Not one drop left. Every little bit of pre-cum is worth money, and Mia likes money very much. A cow should never keep anything from its Princess. Whatever he has is hers. A cow owns nothing of its own. Not even its potentially valuable body. Mia cares nothing for her cow's fatigue or suffering. She only wants what is rightfully hers, which shouldn't be too much to ask from a lowly cum cow. Mia sits on the cows face to entice it to produce more for her. She's frustrated that she's had to wait as long as seventy-six seconds between edges. The cow needs to get to the edge faster so that she can make as much money as she possibly can. Mia shocks it. Maybe that'll get it back on track. The cow cries and screams with pain into Mia's ass. The penalty shocks build and build. Every time the slave does not reach the edge fast enough it receives another punishment shock. Mia loves hearing the cow whimper with pain. It's pleasure levels start to drop and it reaches a state of male exhaustion. Mia fiddles with the machine until the cow is sexually aroused again. She can't collect her profits if the cow isn't aroused enough to be edged for pre-cum. Mia uses the machine to force the money right out of him. He can't help but be stirred by the compound sensorial experience provided by the machine. The cow starts begging its Princess. Mia reminds it that cows are not to talk, only moo. The cow moos as it is denied orgasm after orgasm. It has been edged like this for hours, and will be hours more before it's all over. Even when his shift has ended, his Princess will never be sated. There is no way he can fulfill her inexhaustible desire for material things. His body will give out long before her need for more and more of everything. When Mia has finished using the cum cow's erection, she removes it and puts the cow away for the night. 15:40 long)
