The guide stopped in front of a door and smiled at them.
"The machine doesn't feel as good as a hand of course but ... well, I have said that a cow-girl's body is made for milk production. Don't you think the process would go better if the body was designed to make milking feel good?"
At these words, the guide opened the door. They understood immediately why the door was soundproof - the song of many women moaning with pleasure was very loud.
They entered the room. In the center of a very large room were around forty of the milking machines. Ten cow-girls sat around it, pleased to be milked. Christian scanned the room, stopping to look at one who had horns, ears, and a tail. The four nipples of her udder were connected to the machine. Emilio himself noticed the cow-girl he had seen earlier in the reception area. Her torso was nude, but she was at least wearing her jeans. Both cow-girls appeared to be in heat, moaning as milk went out of their breasts and udders.
The busty one looked like she had an orgasm, crying out as milk flowed out of her. She stopped, exhausted. Then, after just one or two minutes, she pushed a button and the milking process re-started.
"I never had a girlfriend who had that much fun with me," said Christian, totally lost in the view.
Emilio didn't answer. He was trying to figure out how the cow-girls could get any pleasure from something like that. He wondered what it felt like ... and it disturbed him.
After some time, they saw different cow-girls stop and leave, quickly replaced as new cow-girls entered the room and began milking. The machines looked like they could be adapted for all types of morphologies (even the four-breasted one).
The voice of the amused guide surprised them.
"You probably don't realize it, but you have been here for over 15 minutes. I think it is time to move on to the next area."
