It's been almost a month since I was kept as a slave dog. As an indoor dog, I have become a daily routine for my master to satisfy his sexual needs after he comes home and before he goes to bed. However, he gradually gets bored of that and shows little interest in my vagina, and instead trains my other hole, my anus. During the day, I work as a space designer and live a life of luxury, but the truth is that I want to master the path of a masochistic animal, one that believes that suffering is beautiful.
