Write a sci-fi story: Aliens have conquered the world and slaved humans. They are especially interested in human milk. Every year, girls over 18 are collected by the aliens and turned into "HuCows". They are stripped naked and put into milking stalls, which are machines that suck their tits and stimulate them sexually at clit and vagina by vibration. The aliens treat the girls like animals and have no mercy and abuse them without any concern. Tell the story of NAME_1, a girl that is catched and put into the milking machine. Write how she feels to get used like that with no escape for years.
