In the garden Saturday night,mom was out watering the plants and doing the garden and dad was getting ready to go out. Mom and dad were going out for a party and would be back only the next evening. Once they went out I sneaked into my dad's room and saw that my sis was pulling out 500$ from his locker. To my worst nightmare she saw me too. She stared at me and walked towards me. I had a cunning grin on my face. She said, "This is going to stay just between the both of us right honey." I replied "No way." She said, "You seem to be very confident about that honey..." Saying that she sprang her hands and held my balls and a tight grip it was that I felt all the strength and power and energy in me draining out of me into her. Then I slowly collapsed to the floor with the face of a victim and the grin I had on my face had come up in her face. When I fell to the floor, she wasted no time. She kicked my stomach and sunk her feet into my stomach. I was confident at this moment that I was the victim. She was looking down at me and laughing. She then very delicately placed her feet on my face and pressed them lightly to my face. She then ordered, "What are you waiting for? Kiss it." I was terrified at the whole scene and I just kissed her foot. She laughed at me. She said, "Now i need some money. Im going to leave this back but you are going to help me." She put the money back in the locker and she held me by my hair and she pulled me to my room. She knew that I had a locker too in my room and she asked me to give her the keys. I gave it to her. In it I had 7520$. That was my 3 years saving I had for getting a bike. She took all of it. She said, "Now before i finish using this up I want you to save more money and give me. Is that clear." I said yes. She then laughed again. She said, "You are going to obey anything that I say. Are you trying to be my slave. Yeah thats good maybe you can be my slave." I never uttered a word. She then sat on the bed and she stretched her legs and lay down. She said, "Here now I want you to give me a good massage, you bitch." I could not help it but she was controlling me. I was massaging her feet and when I stopped after a while she would kick my face and I would start all over again. Then I began to get back to consciousness. I said, "Nicole! Maybe we should stop. You are my sister. I think what we are doing is a mistake." She turned around and stared at me. She said, "You are right. You are my little brother and you must obey whatever I ask you to do. You have to serve me like you are my slave." Her voice is very hypnotizing and her choice of words trapped me like prey. She said, "Now get up. I will set things right for you." I got up. She then held my balls again and when I was totally disabled she pulled out my cock and started to jerk it hard. It was like she had the remote control with which she could control me. When I was totally under her control she said, "Don't you feel like being my slave and obeying my orders." I said yes. "Don't you want to be my foot stool. massage my foot and be my ass cushion." I painfully said yes. She then slowly released me and she resumed her position and I began to massage her feet. After a while she turned around again and she smiled at me. She said, "It is so good to have you as my slave." She then slowly got her feet to my face and in moments I was busy kissing licking and sucking on her feet. She said, "There you are. my foot slave." She then kicked my face off. She got up. She removed her skirt and undid her panties. She showed me her beautiful ass. It was big. bigger than my head. She said, "You want to kiss my ass. " I waited no more. I bend forward. knelt down and kissed her beautiful ass. She laughed. She then showed me her asshole and asked me to lick it. I shoved my tongue in her asshole and began to lick her asshole. As I was licking she flapped her ass cheeks frequently to let them slap my face from two sides. It was unbelievable and so lovable. She then was confident that she had me trapped completely. She said, "Now as long as you remain my slave, mom and dad will not come to know. The moment you stop serving me and disobeying me, I will give you the worst embarrassment of your life." I agreed with whatever she said and whatever she wanted. She then said, "You are to have no girl friends. I should be the only woman in your life. You must beg to get the permission to jerk off." Are you ready??? I agreed to all her conditions. She was so happy to trap me so easily and I was equally happy to fall prey to her trap. She held me by my hair and slapped my face and I stood kneeling like a dog in front of her. She laughed at me. She then said, "Ok now tell me what do you want from me to approve of your good slavery, my dear brother." I said, "I want to get smothered in your ass. I want you to tie me to your bed and sit on my face and my face must be fully inserted inside your ass and you must not let me breathe and I must pass out there." She smiled at me. She spat on my face and her spit rolled down my face. She then said, "So you like to stay inside my ass, is it? my boy" I looked up at her with burning hopes. She then slapped my face again. She said, "Now I want you to beg me for it." I was on my knees. I bend over and held her feet. I then kissed her foot and she kicked my face away. I begged her like a dog and she kept teasing me and made me feel completely like a dog that I was.At last she said, "all right, but you must earn your price. I want you to go downstairs with me and in front of me I want you to kneel down and kiss the maid's ass. If you do it I will give you your price." I then went downstairs with her. The maid was washing the dishes. My sis went to the kitchen first. I went behind her. Without the maid noticing, I knelt down behind her and quickly kissed her ass. My sis laughed hardly and maid was shocked. Then my sis explained to her the whole matter. The maid laughed at me. She was the age of my mom. She promised not to speak of this to my mom. She then lifted her skirt and asked me to kiss it once more. I knelt down and as I was kissing she held my hair and forced my ass up her ass and she rubbed her asshole with my face and then released me. She said, "Hey Nicole. Thanks. when you not here he is going to give me good service." My sis said, "He better." My sis took me to her room. She stripped me naked and she too got naked. She then lay me on her bed. She cuffed my hands to a beam on the wall and tied my legs to the bed and in additional strapped a band across my stomach so that i would stay still while she was on. She then said, "Listen, you bitch!!! I have got these 2 dvds. Im going to watch them and will rise only when i finish watching these movies. See I have got snacks here with me. You want to get smothered right. You got it." Before she sat, I asked whether I will die out if she smothered me for long. She said, "Im not quite sure of that. Anyway we will find out. If you live longer after my smother then you are the kind of guy i need, the right fit slave and then your life is mine." Saying that she climbed on the bed. She showed me her ass and she she lowered her ass right on my face. My full face went inside her ass cheeks. Her ass cheeks covered upto my ears. Her ass is that big. I felt a darkness and smelled her ass. After long,I was smothered and I felt like I was passing out. She knew that I was struggling. She changed her position. The weight on my face increased and my face went deeper. I could no longer feel the smell. I was growing numb. In regular intervals she pinched and twisted my nipples. She was saying something but I could not hear. Soon unconsciousness conquered me and I had passed out not knowing what happened later. Then after long, i really dont know how long but it was long. I felt a slap on my face and I woke up. It was night and it was my sister. She said, "You did a good job. Still alive.hmmm. now you are all mine and Im not leaving you at all. You have been out for 6 hours. Get up, I need some licking." The rest of the night she rode my face and I licked and munched her pussy and all I remember was that she came atleast 5 times into my mouth and after that she still continued riding my face and I continued tonguing her. She got so wild that she grabbed my hair and pulled out a few strands. She is one true goddess. Now its a routine that a day atleast 5 times she grabs and twists an squeezes and punctures my balls. Of course it hurts. I will have her old panties in my mouth so that I wont scream. If she forgets I will have to beg her for it and at night she can sleep only if my head is between her thighs.
