when I was around 10 years old my sister would constantly try to hit me in my privates. I was walking around always on guard so as to not get hit in the nuts. When she managed to score one she would laugh at me lying there on the floor gasping for air. She is older than me and much larger so I was at a real disadvantage when she would chase me down. After much ball smacking she decided one day that she wanted to actually touch me instead of just smacking it, she got on top of me and got my pants down. She started pulling so hard on me that I thought it was going to get ripped off. Soon I was hard and she was just stroking away and pulling on my cock very roughly. She would do this all the time and some days my cock was raw from her stroking it so much.

Time went by and I grew up, my sister turned into this woman who could not get a job or a boyfriend and soon she was just sitting on the couch all day watching tv. I came home from school one day and we argued about things, she got up and started trying to wrestle me down again and then tried to kick me in the balls. I grabbed her and forced down and started pulling her clothes off. I pinched her nipples until one of them was turning practically purple, she was yelling so much and started crying. I just told her see how it feels to be smacked around and then I rolled her over and spanked her ass until it was red. She was so pissed off she could hardly talk. I got her legs pulled up and was able to spank her pussy a few good times but the look on her face told me she was done and I had slapped her pussy pretty good. I took off my pants and pulled my cock out looking at her on the floor. I sat on her chest and told her to open her mouth, she told me she would bite it if I stuck it in her mouth so I got her spread again and spanked her pussy some more. She was yelling for me to stop and agreed to suck me off, I told her she was going to get face fucked and not enjoy it. I got on top of her again and pulled her hands up above her head. I stroked my cock in and out of her mouth until she was gagging, her face was so red. I came and she started really gagging but I just kept shoving it in as she twisted around trying to get it out of her mouth.

I told her that the same thing was going to happen tomorrow if she did not start cleaning up around the house. When I got home the next day the house was still a mess so I spanked her again and made her suck me off. She finally got the message and started doing chores but I would still once a week or so strip her naked and spank her just for the things she did to me when I was younger.
