Growing Up With Sister

So....many years ago when sister and I were kids she walked in on me as I was lying on my bed naked and jerking off wildly (I was a teenager so you know what I mean ).  She was a little younger and we were both shocked but I kept going and she watched me shoot ribbons of young hot cum on my stomach and chest! She ran out into her room and slammed her door....later that day she asked what it was she had seen me doing. I tried to explain but it didn't seem to register with her so I told her maybe another day she could watch and she agreed. We were home everyday after school for at least 4 hours and our parents did go out often for business reasons.

Two days later after school she asked if it would be ok to watch and I stripped in seconds lol and was on my back....she stood there eyes wide open and watched me get hard! She didn't say much, was just watching me stroke and as I got close I told her to watch because it was going to happen .... and it sure did....she was amazed and started asking what it was, why it happened etc. and then she asked if she could touch it! I said touch what and she said this stuff. I told her sure, all you want...she was feeling it and rubbing it between her fingers saying it was hot and sticky lol.

This became an almost everyday thing now...she loved watching it and swore she would never tell what we were doing.....around a month later she asked if she could try doing it for me! Now I ask you what teen boy wouldn't let any female touch his cock? Well once again I'm on my bed naked but this time I told her if she wanted to do it she needed to be naked too! She hesitated a bit but there it was hard as a rock throbbing lol...she took everything off! Seeing her nubile titties and pretty much no hair on her pussy almost made me cum just looking! She grabbed my cock and started jerking me off and I came in seconds! She was so proud of herself that she made it "spit"! lololol.....this went on now every day and either she would come to me naked and asking "can we" or I would ask her.

After a week or so I would grab at her little titties as she was jerking me off and then I would slide a finger down her pussy slit...it was amazing! She was wet!!! One day I decided to show her a porn magazine which showed a girl/woman sucking a guy's cock....she looked at me naked and looked at my cock and said is that what you want me to do? Of course I said yes and said....well look, girls are supposed to do this! .....she had my cock in her hand and brought her head down to my cock head, it was already leaking pre cum and she licked the head taking some of the pre cum into her mouth! I almost shot my load right then!

I did offer her some assistance by sort of pushing her head down and then it happened! My cock was inside my sister's mouth! So warm and hot and then she started to instinctively ....suck! I shot the biggest load right in her mouth and she started to pull back and I held her head!  When I was done she was almost in tears and spitting my cum out on to my stomach... I told her how great she was and that it's another thing girls like and they do swallow it too.

Long story short....the next time she sucked my cock like a pro and swallowed my load and.... it continued for years as well as 69 and fucking .....it was a great time !
