"You are my cow――" Every time her collar is tightened, her breasts are squeezed, and she is forced to make a sound, her reason is eroded, and she is trained as just a 'sex disposal animal'. Her body, where even shame and pain turn into pleasure, twitches, is milked, and enjoys herself while crying at the command of her master. Her pride as a human being and even her name are taken away, and she continues to serve, cry, and cum. Please see to the end the fate of a woman whose extreme masochistic desires run wild and is completed as an 'animal'.
