"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.
