When I was in my early teens, as most boys do, I would jack off every chance I got. I had a place in the woods behind our house where I had hid a couple of my Dad's old playboys and would go out there to jack off. Some days I would do it 4 or 5 times and still want to do it more. One time when I was out there I thought I had seen someone move off in the distance but couldn't be sure because of the woods. I didn't stop and continued to go out there when I needed some relief. A couple of weeks after I thought I had seen someone I was back at it when I noticed what looked like a shoe sticking out beside a tree about 30 feet away from me. I switched from looking at the mags to checking to see if someone were there and after a few minutes I looked up and the thing I had seen was gone. I got nervous so I put my cock away, zipped up and went inside. We lived in an area where we didn't have any close neighbors so I was scared to death that it was one of my siblings who had seen me.

I was on pins and needles for a couple of days but no one mentioned it or acted any differently so I made my way back out there first chance I found. I eased around to make sure no one was around before going to my spot and dropping my shorts. I got really into it and didn't notice my sister standing about 5 feet behind me until she spoke to me. I was stunned and couldn't move for a second. I dropped my magazine and grabbed my shorts and started to run off when she yelled to hang on. I stopped and turned to face her and that was when I noticed she had her top pulled up and was pinching her nipples. I didn't know what to do or say but she did. She told me to come back over to her and I did. My sister was kind of chunky and had some huge tits and fantastic nipples. When I got to her she told me to take my cock back out and to finish what I had started. I said no way I was going to do that in front of her and that was when she told me that she had watched me do it hundreds of times and that she had even come over after I left and found some of my cum and that she had even tasted it several times. I still said I couldn't but she wouldn't take no for an answer and reached over and yanked my shorts down. She squeezed my cock and grabbed my balls and said not to make her ask again.

Reluctantly I grabbed my cock and started stroking it while looking at her fat titties. She kept hold of my balls with one hand and pinched her nipples with the other. I finally got into it and reached out and grabbed her tits and gave them a squeeze. She moaned and it felt like my dick grew longer when she did. I was stroking away like a mad man when she asked me if I wanted to see her pussy. Boy did I. She slipped her shorts down and slid her finger up along her slit and touched it to my lips. I was in heaven as I stroked my cock faster than I ever had. She was touching herself and moaning when I said I was about to cum. She stopped and asked if I would cum on her tits. Hell yeah I said and had her kneel down as I stroked away until I shot my load on her tits and face. She shook a little and was rubbing my cum all over her tits and licking her fingers. I eased up to her and touched her lips with my cock and asked her to clean me up. She gladly did and when she was done we both wanted more. We didn't fuck that day but eventually did. For weeks after that day every time I went out to my spot she would follow me and we would go a little farther with each other until we finally had sex. That was about 30 years ago and we still hook up from time to time. Just this past Saturday she gave me head while watching the football game. My wife doesn't know and never will but I so want to see them go at it together.
