When he came back he was clutching my own clothes that he had confiscated yesterday.
"These rags should do, off you go Samson, there's a good boy." I realised now that I was no longer just a 'human dog' to him, but was now being totally humiliated in whatever way he wanted. Knowing that he had incriminating photos of me, I felt really turned on that I had to do whatever this nerdy little geek asked of me and so I took hold of my own clothes and used them to mop up his piss from the floor of the bathroom.
"Samson is too much of a boy dog's name for a sissy dog like you, so I'm renaming you 'Daisy'. I also think you should have your chest, legs, arms and armpits shaved because a little girl dog like you should be completely hairless. Wait here."
After a few minutes, he returned with his ugly, fat sister. He'd obviously just woken her up as well because she looked even more repulsive than yesterday, and was dressed in a grubby pink dressing gown that didn't really fit very well. When she saw me pathetically crouched naked on the floor, covered in her brother's piss, wearing a dog collar, she whispered something to her brother and they both giggled at me.
"Come over here, Daisy, there's a good little girl, I'll shave you and make you look all pretty for your master, Kevin," she said laughing to herself.
Kevin stood in the doorway in his white pants, which were tenting with his obvious erection as he watched his sister use all of her shaving products to gradually remove all of my manly chest, leg, arm and armpit hair. It took quite a while, but it really turned me on and she kept touching my little cock teasingly as she shaved me. She was so ugly she'd have been so out of my league if I had seen her at one of the pubs or clubs in town when I was out drinking with my friends, but now I was almost begging her to play with my little cock as she humiliated me in front of her geeky brother. When she'd finished, and I was told to stand up for them both to inspect me, I was completely degraded and actually felt less like a man; my legs and arms looked like a female's and my shaved little cock was the only sign that I was male at all, although I now looked like I did before I hit puberty. With the exception of a buzzed crew cut, I was completely hairless.
"Before you come into work tomorrow I want you to go and get a tattoo on your shoulder that says 'my name is Daisy' so that all your mates from the gym can laugh at you when you take a shower. And I think we'll enter you into another dog show next weekend so you'd better come here every night after work to practice in front of my family. Now put your clothes on and go home."
Far from being something I did every now and then for my own pleasure, Kevin was going to get revenge for all the times the older, good looking lads had bullied and humiliated him at school by making my whole life utterly humiliating, and there was nothing I could do about it. The urine had dried on my hair and body and I got dressed into my damp, piss soaked clothes, which now stank like a public toilet. Kevin went back to his room and I hurried out of the house as fast as I could. Once I was home and lying on my own bed thinking about what my life would be like now as Kevin's pet, I started to get hard again and couldn't help grabbing hold of my pathetic little cock and stroking it furiously for a few seconds until I came violently all over my smooth chest and face. I lay back on the bed and let the cum dry slowly on my skin, managing to humiliate myself by not getting rid of it.
