I awoke to find myself curled up on the end of my sister's bed like you would find a dog, not that it mattered, that was how she treated me.

I looked around the room and realized that my sister wasn't there. I stretched out and crawled of the bed, then crawled all around the house and noticed my Cassy wasn't anywhere to be found.

I went into the kitchen and found the dog dishes filled with a note taped to the cupboard in front of them.

'I made you some breakfast, I expect you to eat it all. I will be home soon, and expect you to mind your manners. You should know the rules and what to expect if you disobey.' Was all the note said.

I looked into the dishes and I must say, it didn't look as inviting as yesterday, and the water in the other bowl...Was YELLOW!

I started to get teary eyed. It was bad enough having to wear her pee, but now she was expecting me to drink it? And worse yet, to do it even when she isn't here?

I think I just stared at the bowls for a moment before deciding that I wasn't going to sink that low. I stood up and walked over to the TV and sat down on the couch, grabbed the remote and turned it on.

At the same moment, I noticed that didn't have the 'tail' in me anymore. Not that I minded one bit, but what the hell was going on?

Cassy caught me by surprise when she got home. I didn't even see here come into the room.

"WHAT THE FUCK IS THIS!" She screamed at me.

I jumped so high off the couch that I must have looked like one of those comical pictures of a cat hanging from the ceiling.

I fell to the floor feeling like I was having a heart attack. Wide eyed, and trying to catch my breath.

"I leave for a couple of hours, nice enough to take your tail out, and leave you breakfast, and I find you lying on the couch like a BAD DOG, and you haven't even touched your food!" She continued.

I started shaking, terrified by her yelling at me. I was so scared of her that I actually wet myself right there on the floor.

"DAMN YOU, LOOK AT THIS MESS!" She yelled, "GOD, I thought we finally had you house broken... and all over the CARPET!"

I started sobbing.

"OK, TALK! Why did you not obey my directions?" She asked.

I looked up at her, not sure if I could really talk or just bark at her.

"I TOLD YOU TO TALK! It's the only chance you are going to have for a while," She said angrily.

I don't know why, but I started yelling at her about everything, finally ending with her 'Breakfast'. "I DON'T KNOW WHAT THAT SLOP IS, BUT I WON'T EAT IT! AND I'M CERTAINELY NOT WASHING IT DOWN WITH YOUR PEE!" I screamed.

Her anger flared up so fast that I couldn't have reacted if I wanted to. She grabbed me by the hair and dragged me into the kitchen, to the bowls on the floor. She shoved my face to the 'slop' first.

"This is biscuits & gravy, your favorite breakfast if I remember!" She said before lifting my face to the other bowl.

"AND THIS...IS NOT MY PISS!" She screamed again, pushing my face into the bowl of yellow liquid. "DRINK!"

Sniffling, I took a sip. 'Lemonade, oh shit, it was just lemonade,' I thought. 'She made me my favorite breakfast, and I stuck my nose up at it without even thinking!'

"You were so good last night that I thought I would do something special for you, but you had to be a little Bitch again!" She started. "FINE! You didn't want it, then we just have to find something else for you."

She picked up the bowls and tossed out all the contents before filling the food dish with a can of dog food again, and setting it on the floor.

"You can eat that...And as for the water, you can just drink that straight from the toilet like most dogs do," She said looking down at me with fury. "Before you eat, go clean up the mess you made on the carpet."

I went over and grabbed the carpet cleaner and a rag, and went to work scrubbing the floor as my sister sat on the couch, watching me with angry eyes. I knew that things had just gotten worse for me that day.

Just before I had finished with the carpet, Cassy got up and walked into the bathroom. She didn't shut the door. I suppose she did that so I could hear her pee. I also noticed that she didn't flush when she finished. My heart sank. I had finally got on her good side the night before to have fallen so far because I was so stupid and not even sniffed to see what she left for me to eat.

Cassy sat at the kitchen table as I choked down the dog food. It was some kind of meat chunks in gravy. It was disgusting, cold, and slimy. I thought I was going to throw up, but I managed to keep it down. I needed to wash it down with something, but I knew what that was going to be, and I sure as hell didn't want that.

After I had licked the bowl clean, I looked at my sister, hoping that she would take some pity on me, but that was just hopeless at this point.

I was thirsty, and desperate to get this horrible taste out of my mouth, so I crawled to the bathroom. My sister followed me in there, watching silently as I brought my face to the toilet bowl.

I looked into the bowl, and could see the water in there, tainted with my sister's piss. I looked to her again, tears in my eyes'.

"You brought this on yourself today," She said. "I was even thinking you learned your lessen, and was going to let you enjoy the rest of the week, but you just couldn't help yourself, and pissed me off again. So drink up as much as you like puppy, it's all you get now."

I looked down into the bowl again just as a tear drop fell from my eye into the yellow tinted water below.

I closed my eyes' and stuck my face into the cold smelly water. I started lapping at the water, tasting the acrid salty water. I got a couple of swallows down before I started gagging and coughing. I was sure I was going to puke, and did everything I could not to.

I took my head out of the toilet bowl, and crawled out of the bathroom, crying. I didn't even look up at my sister as I crawled past her. I was just outside of the bathroom when I heard the toilet flush. I sunk even lower.

Before I got too far, my sister caught up to me and grabbed me by the collar (Which was all I was wearing). "Where do you think you are going?" She asked me.

She dragged me by my collar out to the garage where our dad had some saw horses set up. She pulled me over to one, tossed an old wool blanket over it, and told me to climb on up.

I wasn't sure what she was going to do now, but if I refused I knew she would do something far worse then what she was thinking of now, so I did as I was told.

She tied my thighs to the legs of the saw horse, and then tied my ankles to my thighs. Pulling my body down tight to the board, she attached the leash to my collar and tied that to the bar between the legs of the saw horse in front of me. She then tied my arms to the legs in front of me, and another rope around my back.

I couldn't move an inch, and the wool blanket was making me feel all itchy and uncomfortable.

Cassy pulled her panties off from under her skirt and shoved them in my mouth. Then she picked up a long wooden ruler off the work bench. "Now I want you to think about everything you could have done to prevent this from happening, Lucy."

I was starting to hyperventilate as she walked to the side of me, rubbing the ruler against my butt.

I didn't know why she shoved her panties in my mouth till she lifted the ruler and brought it back down hard across my butt, flattening my cheeks. I think my scream would have woke the dead had I been able to scream! The force of her thrust made me move slightly in my bonds, rubbing my body across the wool.

Fire engulfed my ass, as an itchy scratching moved all over my small breasts, stomach, pubic mound.

Cassy laid into me for a good 10 minutes, but to me, it felt like an hour or more. I couldn't even imagine what my ass must look like, but it felt like the pain would never go away. How wrong I was about that.

I was sobbing so hard, I didn't even see Cassy walk in front of me, set down the long wooden ruler and pick up a smaller school one.

She got behind me again and I felt her hand run along my now bruised butt cheek. God, her fingers felt like razors moving across my very sore behind.

I was pulled from the pain in my rear when she flicked the smaller ruler hard onto my exposed pussy lips! I started screaming into the gag, and thrashed against my bonds and the wool blanket beneath me, crying and sobbing with renewed vigor.

I barely noticed when her fingers starting rubbing my pussy lips. I finally noticed when she started blowing on my sex, and I started feeling some pleasure. I even started getting a little wet from the light touch and cooling air.

I moaned into the gag in my mouth, when I felt her pull my lips apart... Then everything went black as my body erupted in pain from my sister bringing the ruler down hard on my erect little clit, causing me to pass out.

I woke a few hours later, finding myself lying on the couch again. My sister was in the kitchen making some food.

It smelt so good, but as she sat at the table to eat, I noticed that she didn't make anything for me.

I could tell she was still mad at me, and I didn't know what to do. So I crawled into the kitchen, and knelt down at her feet, trying to keep any weight off my sore behind.

She looked down at me for a moment before going back to her food. Without a second look down at me she said, "If you're hungry, I'm sure you can find something to eat."

I was confused, 'what did that mean?' I wondered. Then it hit me like a ton of bricks: 'Now I want you to think about everything you could have done to prevent this from happening, Lucy,' she had told me earlier.

I moved under the table, and saw my sister scoot forward in her chair a bit, lifting her skirt up. I slowly brought my face between her thighs; I could smell her intoxicating aroma. A smell that disgusted me a few days ago.

I breathed her in before wrapping my upper lips against her lower ones. I was coming to love this taste, the feel of her pubic hair tickling my nose.

I have never felt as close to my sister as I did at these moments. I wanted to please her, so she wouldn't hurt me again.

I felt awful when she got up to clear her plate, I couldn't even get her off. 'She is still mad at me' was all I could think.

As she was standing at the sink washing her dishes, I got an idea, although it was my idea, I didn't like what I was about to do, but I had to make her happier with me.

I think I shocked even her when I crawled out from under the table and stuck my face under the back of her skirt.

I heard her gasp and drop one of the pans she was cleaning when I pushed my face between her butt cheeks and licked her asshole.

"Oooh gawd," she moan, reaching back to grab hold of my head. "You really do want to please me don't you? Good girl."

I couldn't believe I was licking someone's butt, but to be honest, it wasn't as nasty as I thought it would be. Truth be told, I really liked it, and even more, I loved the reaction I was getting out of my sister.

She let me lick her for another 5 minutes while she moaned and trembled. When she finally pulled my face from her ass, she turned and knelt down level with me.

She stared me in the eyes for what felt like a lifetime before she shocked me by grabbing the back of my head, leaning in, and kissing me!

My first kiss... It felt so strange when her tongue entered my mouth. I wasn't sure what to do, but soon I was moaning and shuddering into her mouth. When she broke the kiss off and stood up, I found myself still kissing the air.

When I opened my eyes, my sister was standing over me smiling, sort of giggling. I blushed at how stupid I must have looked.

"Alright girl, what would you like to do now?" She asked, talking to me like a dog again.

I thought for a moment, when I realized I needed to pee, and running around outside might be nice too, not to mention keep Cassy in a good mood. So I ran to the back door on my hands and knees, and scratched at the door whimpering.

"Oh, you need to go potty?"

"ARF!"

As soon as she opened the door, I bounded towards 'my tree' and lifted my leg, before she was even outside.

She laughed when I finished and grabbed a stick in my mouth, dropping it in front of her bounding around her barking.

She picked up the stick, and giggling said: "Is this what you want? Huh? Go get it girl," As she tossed the stick.

I don't know why, but I was starting to have fun in my role as her pet. It was exhilarating to be running around the yard naked, pleasing my sister in any way I could.

I got the stick and brought it back, but my sister wasn't there. So I just sat there dumbly holding the stick in my mouth wondering where she went.

She came back a couple minutes later with the tail in her hands. "You just didn't look right fetching a stick without your tail."

I really didn't want that thing back in me, but I could see her point, sort of. I turned around and put my head down and presented her with my ass.

After I had my tail back in my sister gave me a few commands, had me wag my tail, tossed the stick for me, and all the time, I was running around barking. I even tried chasing my tail like a real dog. It was all very embarrassing, but at the same time, so much fun, and my sister was smiling, enjoying my performance.

That night in my sister's room, I got another shock. While I lay on the edge of my sister's bed, she came back from the bathroom wearing nothing, but instead of the sight of her pussy, she had a penis!

My eye's got wide in both the fear and excitement of what saw. Then I heard my sister say; "Come here Lucy, come on girl."

I knelt in front of her, hands planted on the floor, her realistic cock inches from my face.

"Now sweetie, this is going to hurt you a lot more than it will me, but if you're a good girl, things will be better for you the next couple of days," She said as my nervousness started to show on my face.

"Suck my cock. Take it as deep as you can," She said

I didn't know what I was doing, but I tried.

I took the thing in my mouth and tried to push it in, but I went to deep and started to gag. I pulled off of it and looked up at my sister hoping that she wasn't going to do what I thought she would.

"If you don't keep going and try your best, I am going to do my best to push the whole thing into your stomach," She threatened.

I put the fake penis back in my mouth and kept trying to take as much of the 6 inch tube into my mouth as I could, slobbering and gagging on it as I tried.

All of a sudden, I took a deep breath, and swallowed, and found that the thing went all the way into my throat! I didn't mean for it to happen, and from the look on Cassy's face, she didn't either.

My wide eye's on Cassy's face as she grabbed the back of my head and held me there, while her other hand reached down and felt the bulge in my throat.

"HOLY SHIT! I wish you could see what this looks like, your neck is bulging out!" She told me. "There aren't many girls that can deep throat like that, especially not at 11! You got talent!" She explained.

I was feeling pretty proud of myself, even though I felt like I was going to choke to death if she didn't let go of my head.

When she let go of my head, I pulled off coughing.

"You ready to become a woman?" She said.

I wasn't sure if I should talk or not, so I just shook my head.

"AWWW, poor baby. Scared?" She taunted me. "Don't worry, it's going to happen one way or the other, so you can either be good and it will hurt, or you can struggle and it will hurt more."

I just turned around and sat there on my hands and knees waiting.

To my surprise, she grabbed the tail in my butt and pulled it out with a pop.

"Since you're going to be a good girl about this, I am going to help you get over this with as much pleasure as I can manage. Up on the bed, turn over and spread your legs," She told me.

I felt a lump in my throat, and felt a tear run down my cheek. It wasn't a tear of fear or anything, but of a feeling of love for my sister. I can't explain it. I knew what she was about to do was wrong, and how mean that she has been to me this week, but just that little bit of kindness was enough to make me want to let her take my virginity.

I turned over and spread my legs. My sister looked down on me, noticing the worried look on my face, and the tear on my cheek.

I felt her get close, her cock resting on my pussy lips. She poured something on me down there, and I closed my eyes fearing the worse.

Then I felt something sliding into me. I grimaced at the intrusion between my legs, and felt my sister kiss the tear on my face.

Just as I started thinking that this wasn't as bad as I thought it would be, she thrust in hard and broke through my barrier! A new pain shot through me body and I wanted her to pull that thing out of me, but when I opened my mouth to say something, she stuck her tongue in there once more.

When I started to relax, she started to move back and forth. It went from a sharp stabbing pain, to a dull throbbing pain, to numb, to feeling good. I couldn't believe the sensations.

Soon I was moaning, then wrapping my legs around my sister. I was thrusting myself up against her, and then it happened, that exploding feeling from deep within me. I thought Cassy would stop after my body went limp, but no. She fucked me for an hour and a half, pounding me hard, giving me orgasm after orgasm till my body hurt from all the pleasure.

She finally pulled out of me, and collapsed next to me on the bed, panting heavily. She removed her toy, and rolled over onto her stomach.

"If you enjoyed yourself, you should show me how much you appreciated it," She said.

I looked over at her beautiful up turned ass and just buried my face in those cheeks till I heard her start snoring. Then followed suit, and fell into unconsciousness using her butt as a pillow.
