Mark saw his father walk in and begin to set up to milk the cows. Mark knew that if he felt what it was like to be milked as a full cow, he might never want to be human again. Mark resisted the urge and fought through the throbbing pain of his swollen udder to look for a way out. Unfortunately for Mark the only opening he saw was the door to the bull pens. Mark knew that the bulls were free to roam outside and enter their pens at will so hopefully all the bulls would still be outside for Mark to buy some time.
Mark stumbled toward the gate, not used to walking on all fours or weighing almost 5 times his usual weight. Lucky for Mark, the bull pen door never locked when it was shut, so Mark was able to push it open with his snout. Upon opening the gate, a rush of bull musk filled Mark's snout, dazing him momentarily. In his dazed state, Mark was beginning to reconsider going into the bull pen. As Mark thought it out in his mind, his new body betrayed him and continued to walk into the pens. It wasn't until the harsh sound of the gate latching did Mark realize he entered the bull pens and locked the door behind himself. Feeling light-headed, Mark knew the smell of the pens was getting to him - he would have to work quickly before he lost himself to his growing urges...or worse.
