Human Cow - Selling Lucy: Milking, Book 4 (Unabridged‪)‬

Investigative reporter Lucy bit off more than she could chew when she broke into the Science Institute and discovered Dr. Felton's lucrative business; converting pretty young women into human milking cows. Captured by the security guard, she received a large dose of Formula X herself and before long her life became unimportant as long as she was milked regularly and sexually satisfied. Now completely conditioned to her new life, it was time for her to be sold on to a new home so Dr. Felton holds a cattle market.
