A very accommodating sister

I live in a Midwestern town a pretty normal everyday place. My mother passed away about 4 years ago when I was 10 and my sister was 16. Some relatives in California wanted to take us to live with them but we chose to stay with Dad. I think without question that was the right decision he needed us and we wanted to stay close. My sister dad and I were very close knit it was a good family relationship we made it work. When my sister turned 18 she married her high school sweetheart and then moved out not far from us she visited quite often.

I always felt I could ask her anything and didn't feel odd or unusual about anything I would ask her. Father had to go for 3 Days to help his sick brother so that would leave me alone. I wasn't excited about going with him so my sister told him she would come over and make sure I would be okay. I looked at this as being a great opportunity I have been masturbating probably for a couple of years but of course when you live at home you have to be careful about when you do this so as not to get caught.

My sister came by the last day my dad was going to be away to bring some Chinese takeout we had dinner I went in to watch a little TV she cleaned the kitchen up and followed me in sat down on the couch next to me. We made small talk about school and how things were going with me I told her everything was good. I was an average student at best didn't really like school but it was one of those things you got to do I just couldn't wait for it to be over. She asked me if I was seeing any girl in particular I told her no she said she was surprised as she was dating very young and I was almost 15 and still no girlfriend. She asked me if it was okay if she would ask me a personal question couldn't imagine what it might be but I told her yes no problem. She asked me if I had discovered masturbation. This really made me uncomfortable I didn't know what to say do I lie to her and tell her no or do I tell her honestly I've been doing it for a while now?

She said she was sorry she made me uncomfortable with the question and I just told her yes I have discovered it as in school they said that it wasn't abnormal but it was quite usual. She said that's good then she looked at me with a firm face and asked if she could jack me off. I said what she said I want to masturbate you. I told her I don't think that's a good idea you're my sister we are family. She said it's not that big a deal it's just like a massage finished in a wonderful way.

I told her I'm still not sure it's a good idea and then she said to me can you keep a secret? I told her yes no problem and then she told me that for the last 4 years she's been jacking Dad off. I said to her oh my God when does that happen. She said sometimes she pops over for coffee early in the morning and gives him a handjob sometimes later in the evening whenever time is available. She said this happens 2 to 4 times a week and has been ever since mom died. She said I know you think this is terrible but there's no sex involved whatsoever I just stroke him until he has his climax. He is appreciative and it's exciting to me. After jerking off Dad I get so excited I go home and rape my husband.

By now I had a cock that was so hard it could cut glass she asked again if she could stroke me off just a nice massage I would enjoy it and she enjoyed doing it she said it was a fetish whatever that was I didn't understand I told her okay I figured it couldn't hurt and as hard as I was if she didn't do it I was going to have to go into the restroom and take care of it myself. She told me to wait a second went into the bathroom came out with a hand towel and a small bottle of baby oil she pulled down my gym shorts I just leaned back into the recliner she squeezed a small amount of oil onto the head of my dick and massaged it in and started a steady rhythm with her free hand she massaged my balls or where my balls were supposed to be anyway she laughed and told me they disappeared. And then she told me they were making the sperm that I would shoot out soon. She kept stroking from the base to just over the head slow steady strokes sometimes using two hands in a corkscrew motion other times just one hand. This went on for about 7 or 8 minutes and I could feel the pressure building up down in my nuts I told her I was going to ejaculate soon she told me not to let her know she likes surprises. A couple of minutes later the first little bit of sperm squirted out she picked up the pace I shut off four or five good shots across my stomach as far as my chest and one shot hit me in the chin. I don't usually shoot off that much when I jerk myself off. She jerked until it became sensitive and then it softened she used the towel to wipe up all the spunk and to clean me up she went to the bathroom washed her hands. We talked for a few more minutes she asked me if I was okay I said yes it was great. I asked her if she really jacked off Dad or if she just told me that so I would allow her. She told me she would let me know the next time and she would figure out a way I could watch. I don't know why but this really excited me to watch my sister jerk my dad off crazy maybe. About a week later she told me she was coming by after work if I could find a excuse to leave the house she would leave the curtains in the living room cracked just a little bit and if I wasn't there she knew that Dad would be up for getting jerked off.

As she had said she arrived I saw her from up the block I waited until she was in the house a few minutes and then I went down and as she said she had opened the curtains slightly just enough so I could see inside without a problem. Dad was sitting on the couch with a beer she went over to sit next to him and I couldn't hear anything that was being said but they were talking. He then unzipped his pants pulled his shorts down and withdrew his cock my God he could have been in a porno movie it was huge well it was compared to mine anyway and it was really thick. You could tell this was going on for a while like my sister said because she showed no hesitation she went right to work he was very limp unlike myself that was raring to go right away she had to put some work in to getting him hard. That took all of about 10 minutes and while I'm watching this I have a raging hard on unfortunately I'm in a position where I can't do anything about it being in view if cars drive by. She oiled up her hand a little more she oiled up her hand a little more and kept stroking she needed both of those hands to fully stroke his shaft this only went on for about 5 more minutes and he erupted it just kept coming I could only hope to be able to shoot that much, it was everywhere. Like she did with me she cleaned him up with a hand towel. I waited until they were in a non compromising position then I pretended to just arrive at home through the front door my sister gave me a hug told me she was happy to see me dad asked me how my day was.

I told him I had a good day my sister give me a kiss on the cheek said she had to get back home just wanted to come and see Dad. I headed straight for the shower jacked myself off finish my shower collapsed on my bed. Life wasn't so bad
