I stepped off the bus and headed home, with anitsipation of playing xbox and watching tv. When I opened the door to my two-story suburban home I was welcomed by a water balloon to the face. All I could hear was the high pitched laughter of my 13 year old sister Ann. As my vison cleared I could see the 5'4, dirty blond, medium chest, loose clothes wearing demon laughing in the kichen. A playful rage filled my body, but I didn't show it. I slowly took off my backpack and set it on the ground, and then I yelled.

"I'm gonna get you!" I charged her. When she looked up and saw me charging, her eyes shrank. She turned and ran through the kitchen. I barrled around the corner to see my mom and Suzy washing dishes. I slowed for half a second to enjoy the view. Mom is 5' 7 with a supermodel figure, but she has unnaturally large tits. Suzy is much like my mother at 5' 8, she is 'fat' if you ask a supermodel, but she still has those sexy curves. Just like mom her tits are bigger than most 19 year olds. As I looked in awe I could feel a small hard on growing in my pants. A collision with the wall snapped me out of my day dream. I shook off the blow and refouced on my target. Her foot diappered into the tv room. Quickly and quitely I entered the room to find her catching her breath. An evil smile crept up on my face. As quitely as I could I crept behind her, I hovered my hand just over her back. Then I gave her a nice slap on the back. She obviously didn't expect it beacuse she jumped and landed flat on her back. I stood there laughing at the fall that the little brat had just taken. Her eyes filled with hatered* as she stood up and ran upstairs. Once I stopped laughing I turned on the xbox and tv and got ready to play when mom came in and turned the tv off.

"Don't you give me that look." She said "You know damn well why I'm turning off the tv. How can you be so mean to your sister?"

"You don't know how evil the little troll can be." I said "I mean you work from five in the eveing to eight in the moring. You only see her for an hour or twoa day."

"I know that and I don't like it anymore than you do, but my job pays for everything since your father died in Iran. I'm the reason that you have the devices you have, the reason that Suzy can go on the week long college experience thats starts tonight. Which reminds me. Since I'm working and Suzy won't be home you'l need to watch Ann till I get home, and if you don't then you'll never a another minute on this xbox. Am I clear?"

"Yes ma'am." I said with as much sarcasm as I could put in the sentence. Mom gave me a dirty look as she turned to the kitchen and yelled.

"Suzy get your stuff! You need to get going!" Suzy walked in and smiled.

"Don't worry mom. I've already loaded up my car." She looked at me. "Brad try not to make Ann comitt suicide. OK?" I gave a playful smile.

"No promises."I said.

"You might what to try and say goodbye too Ann." Mom said

"Good idea, but then I have to hit the road or I'll never make it." Suzy walked past and started up the stairs. Mom followed close behind. I leaned back and turned the tv on. I filpped through all the channles we got, but nothing was caching my eye. Soon the three women came down the stairs. I threw a goodbye over the back of the couch as the three started their crying fest.

ug I thought she's just going away for a week it's no big deal. Shortly after Suzy left mom said her good nights and left for work. Ann, still upset, went upstrais and closed her door. I sat and watched TV and slowly drifted off. I was suddenly awoken by a noise outside the window. I figured it was just some birds. I looked at the clock and saw it was ten o'clock. Got up to go check on Ann. I slowly opened her door to see she was sleeping on top of her covers. I slowly, carefully lifted her up and moved her covers over, then I tucked her in. I smiled and whispered good night. I left her room by turing off her light and closeing the door. I ploped my self in front of the TV again. Just as I was getting comfy the nosie from outside piped up again. It sounded like someone was hiding in the bushes. I got closer to see if I could figure out what was making the noise. When I got over there, I heard a sound like a machien spinnig up. Then suddnely I was flashed by a bright light. I backed up from the window from shock. I felt really dizzy and sleepy. Then the ground came up to meet me. The last thing I saw was Ann coming down the stairs and she was running towards me. Then I blacked out.

Darkness filled my vision. I could feel that I was laying down on some cold, metal surface. My body slowly came back online. As my head reactivated I could hear something loud and muffled. I lifted my head up a little. My eyes opened slowly and adjusted to the light. Do I smell...Do I smell a hamster? I thought. Suddenly there was a loud slam. I jumped as my body went from fifty-percent active to a hundred percent. I shot up only to be shocked back to the ground. I could not believe my surroundings. I was in some kind of cage, but that wasn't the weird part. What was really weird was I could swear that I was looking out into Ann's room, and everything was huge. I got up and turned around in a stunned circle. I was in Ann's old hamster cage, and there was a piece of paper near to the wheel. I walked over to it, it had huge chicken scratch on it. I did my best to translate.

"Brad" it said "I don't know how else to tell you this but last night I was awake when you tucked me in. I was coming down to thank you and say I was sorry for the water balloon when I saw you fall. I ran over but when I got over there your clothes had vanished and you had lost a foot."

'Lost a foot'? I thought as I looked down at the ground to see both feet still there. Wait does she mean that I had shrunk a foot? She must, I mean there's no other explanation. I continued to read the note.

"I kneelt next to you. I was too scared to touch you, and I'm happy that I didn't. I sat and watched you quickly shrink to only a few inches. Once I was sure it was safe I picked you up, and carried you up to my room. I wanted to make sure you were safe so I put you in Mr. Hamster's old cage. I don't know when or if you'll read this but I have to go to school now. Hope you get better. Ann" I stood there as my brain worked though this new info. Then a thought came to mind.

What time is it? I walked over to the bars and looked for Ann's clock radio. It was next to her bed. 5:05 PM was the time. Suddenly I heard a lot of banging for outside Ann's door. It opened slowly Ann's head appeared around the door. Her face was long and somber.

"Hey." She said.

"Hey." I said as she walked into the room I got a good look at her. She was wearing tight clothes, something she swore she'd never do. She walked over to the cage, and that's when I got a real feel for the size difference. I stood, even with the table and cage to boost me, only to her belly button. I know that because I was staring at it. I looked up my now gigantic sister. Her body flew by as she got on her knees. Her face was in front of me, filling my vision.

"I don't know how this happened." She blurted. "You read the note?"

"Yep. Or at least I tried to, you have got to work on your penmanship." She chuckled.

"Same old Brad, making jokes in the most dreadful situations. Listen until I figure out how this happened, I'm gonna keep mom, and Suzy out of the mix. You're going to have to listen and trust me ok?" I nodded my head. She smiled "Ok good now let's get you out of there so I can lay down the ground rules." She opened my cage, and reached in with her huge hand. She grabbed me and slowly pulled me out. Her hands started to shake. Then she let go, and I has free fallin'. The air flew past my face and into my hair. Seconds before impact I put my arms out to break my fall. Suddenly pain shot through my arms. I laid on the shag carpet arms throbbing in pain. Then the pain started to leave my body. I looked at my arms they didn't hurt anymore. I looked up at Ann to see her bending over to pick me up. She gently cupped me in her hands, and brought me close to her face. She was near tears.

"Ann." I said

"I don't know what came over me. I'm sorry. I'm so, so sorry." She said through watering eyes.

"Ann! I'm fine." I yelled. "Look it does hurt anymore." I started hitting my arms against each other. Ann's eyes filled with wonder, and any sign of sadness had vanished.

"So.....does that mean.....that? You can't die?" I looked over my arms.

"Well, I think it means I can't die by physical damage."

"But what about drowning, or old age?"

"I have no idea, and I'd rather not test it. Now what where those ground rules you were talking about?" An evil smile appeared on her face.

"I think I should explain first. While I saw at school I thought about your.....helpless situation. And I've decided that you are now my pet.

"What!?" I yelled

"You heard me" She said in a mater-of-fact tone. "I said you are now my pet, and as m pet you must listen to your mistress. That reminds me the rules are as follows. One you will address me as mistress nothing else. Two you will do whatever I tell you to do and you'll do it quickly. Finally you will not run away. Break any of these rules and you'll be subjected to varying levels of punishment. First you know how I go for a jog every morning, and when I come back my socks are filled with my sweat. Normally I throw them in that bin over there." She said motioning to the green bin full of clothes and socks so stinky I could smell them from across the room. "Disobey me and they might start ending up in your cage. Second level is you get an up-close and person view of what my socks and feet go through in a day. Get my drift?" I nodded out of fear. "Finally you know that bottle rocket that's sitting in the garage? Well I did a little research on how to work those thing and well I might tie you to the rocket so you can tell me how high it can go, or how it feels to land with no chute. Understand?"

"Yes An-Mistress." I said as rage bubbled inside me. This can't be happening. I thought. My own sister has turned on me. Then a question popped into my head. "Why are you doing this, Mistress?"

"Because you are so cute." She said. "Plus I've been dreaming of this moment for years now. You don't know, brother, how many nights I've toyed with my body imaging you deep inside me. Not your cock I'm talking about your whole body. OH, I'm getting horny just thinking about it. I mean look at my nipples." She lowered me in front of her fully erect nipple.

That's not good. I thought. Most girls lose control over themselves when they get horny, and if she really HAS fantasied me being her sex toy. Then something tells me I'm gonna to get really wet.

"And that's not to mention my wet clit." She said seductively. She lowered me down even more, I was now being held right in front of my 13 year old sister's pussy watching as its juices flowed out from its lips. Ann took her other hand and shoved a few fingers into the young pussy. Her head flipped back in pleasure. Instinct took over as I was brought up and sandwiched up against her tit. Her hand started messaging me into her tit. Milk started squirting from the nipple. Some of the sour substance made it into my mouth. Regardless I had a boner so hard it was starting to hurt. Ann, now covered in sweat, lifted me to her face. In one fluid motion she opened her mouth and threw me in. She rolled me around her mouth like I was candy, and I liked it.

The hell is wrong with me. I thought as I hit my climax. Cum shot from my cock and mixed with her saliva. She spit me out unto her tits, and asked.

"Slave, did I tell you to cum?"

"No Mistress." I said

"As your punishment I banish you to the confines of my pussy till I cum." Without another word she picked me up and shoved me into her deep, dark pussy. A little bit of pussy juice land in my open mouth when I penetrated. It tasted better than anything I'd ever had. It was hot inside my sister's clit. She pushed me in then pulled me out with quickening speed and more force. I could hear her screams of pleasure inside her pussy. Then she screamed "I'M CUMMING!" As a wave of fresh fluids washed over me. She let go of me and I rode the wave of cum out onto her bedspread. Both of us breathing heavily after the most wonderful fuck we'd had ever had.

As I laid there, between my sister's thighs, I could feel her delicious cum start to harden. "Mis....Mistress." I said

"Yes.....slave?" She said in between heavy breaths.

"Could you clean me off? It's getting hard to move."

"Yes, Yes of course. Just give me a second."

"Mistress." I said as I slowly sat up. "If you don't mind my asking, but why weren't you shy about telling me your fantasy? And how are you not a virgin?" Her breathing stopped for a few seconds. Then she sat up with a distant look in her eyes and said.

"About a year ago, I was trying to go to sleep, and I was failing horribly. Then I heard some weird sounds coming from Suzy's room. It was mainly screaming so I went to see if she needed help or was in trouble. When I opened her door I saw something that still scares me to this day. Suz was naked with a dildo up her pussy and a porno playing on her laptop. At first I was confused, then I was horrified." She said taking a deep breath. "I ran back to my room in silent fear. When I woke up I convinced myself that what I was saw was a dream, but I couldn't get it out of my head. Every night for the next three months I came up here right after dinner to do some....research. Everything from lesbian pornos to google searches. Once I learned everything I thought I could, I swiped one of Suzy's dildos and, once everyone had gone to bed I took it out the dildo and slowly inserted it into my clit. It hurt like you would no believe. Blood ran down my legs. I wanted to take it out, but all the women in the internet loved it so I kept pushing. After it was in all the way I blacked out. When I woke up it was early morning, and no one was up yet. When I tried to get up I felt my first bit of sexually joy shoot up my spine, so I took the dildo and fucked myself. I was drowning in ecstasy, the only thing that brought me back to reality was my first orgasm."

"Well I said that explains how you're not a virgin, but what about your fantasy?" I asked.

"On one of my searches." She said still refusing to look down. "I stumbled across a site called giantess world, and let me tell you this site is a gateway site. Soon after the discovery I found giantess booru, and it was all downhill from there." She finally looked down and smiled. "Now let's get you cleaned up." She gently picked me up and carried me to the bathroom down stairs. She filled the sink with hot water as she filled the tub with hot water. Once both were full we slipped into our pools of water. The warm water made my muscles relax, and it felt so good. We sat without speaking, relaxing and unwinding in the hot water. After a long time Ann got out of her, now dirty, witches brew of water. She started to dry herself off. Once she got the towel to stay on her dripping wet body, she came over and gave me a hand cloth to use as a towel. We dried off and she took me back to her room. She put on her dog printed pjs.

"Um, Mistress, do I get any clothes?" I asked.

"No silly, pets don't need clothes." She responded, as she picked me up and took me to the kitchen. She set me down on the counter then went to the frig and pulled out a block of cheese. A cold burst of air flew over my naked body when she opened the door. I shivered a little bit. Then she went over to the cabinet and pulled out two glasses, one about twice my size and the other was just below my head. She pulled out a giant knife, one so shiny I could see my whole body in the refection. A cold chill shot up my body as I was reminded of my fragile state. She cut up the cheese into small pieces, and put some of it onto a plate and some into her mouth. I gapped in awe of her mouth.

No bad Brad! I thought as I looked away and shook my head. I can't believe I'm staring at my thirteen year old sister's mouth. Like I want to be in there, and yet. I could fell something inside me, some primal, urge, wanting to take over and throw me in her mouth. When I looked back she had lowered the plated just below me. When I looked at her she motioned for me got get on. Once I did she took the plate, me and the cup, that she had filled while I was looking away, to the TV room. She pulled down the couch table and set everything down on it. Ann turned the on and flipped the channel to some reality show.

"You can drink from this cup." She said. "Eat as much as you can you'll need your strength up for tomorrow."

Oh great. I thought. What does she have planned for me now? She pulled a can of Mountain Dew from the folds of the couch. She looked at me and smiled.

"I keep soda hidden all over the house. Been doin' it ever since mom made the 'no soda' rule. Now let's sit back and enjoy the show." We did just that. I snacked on the cheese and climbed over the edge of the cup to drink every now and again. Then a thought came to my mind. I pondered and pondered, but could not come up with a realist answer, so I turned to Ann and said.

"Mistress, I just had a thought."

"Oh, no. What have I told you about thinking?" Came her sarcastic reply.

"You use a lot of curses. Where did you pick those up from? I mean, I know porn vids curse but you can't be as comfortable as you clearly are with those words after only a year." She sighed and said.

"Those words have been floating around the school for a few years now. Anderson Middle School is different from when you went. Everyone curses, even the teachers have stopped censoring themselves. The only time they do is when the principal or someone from admin shows up. I learned most of the words from there. It wasn't until I heard them on the porn vids that I knew they were used outside of school, and now that Suzy is gone for a week, mom working all night, and you at this size I feel normal cursing. Let's forget about that and just enjoy the show." She sat back and resumed eating the bigger blocks of cheese. We ate for a while until around eleven o'clock. When Ann put the plate and cup in the sink and took me up stairs. She flipped open my cage and set me down inside. Then she closed the door and kneeled in front of the cage. "Remember earlier, when you came in my mouth, I banished you to my pussy? Well, after thinking on it, I've decided to give you a real punishment." My mouth hit the floor.

"Wh wh what?" I stammered as fear and anger ran ramped through my body. "What will the punishment be Mistress?"

"Get some rest. You'll need it tomorrow." Was her only response. She stood up, turned off her light, and crawled into bed, leaving me in shocked silence. I sat there on the cold, metal floor trying to understand what just happened. As I worried I could hear a small voice.

"Have no fear you will be free in days." It said in a ghostly thin voice.

"What? Who's there?" I said in a panic. I turned around in a small circle.

"Have no fear you will be free in days." It repeated.

"Hello? What do you mean free?" I said in a claimer tone. I sat sit for a few seconds awaiting a response, but none came. With fresh fear coursing through my veins I laid down shaking. I closed my eyes and cried myself to sleep.
