I am about 3 years older than my sister
Anne. We started exploring sex when were young.I was about 12 and she was 9. It was very exciting but scarey as I had only rudimentary knowledge of the facts of life and I thought she could get pregnant. As wae got a couple of years older urges got stronger and I had sexith Anne on trip into the countryside with our parents. We left them behind and it was deserted. We had sex by a stream. My parentsboth worked late and after we got in from school one day Ient to Annes bedroom. She was still in her uniform. She was still just starting to develop physically but when I took her pants off she had fine downy hair between her legs. We didnt know about foreplay and I quickly moved on top of Anne. I was pushing and she guided the tip between into her slit. In seconds I was inside her. Anne opened her legs wider and I penetrated her fully. I could feel the tip of my penis sliding against something and I now now it was her cervix. After urgent,eager thrusts, I was suddenly squirting hot jets of my ***** all over the entrance of Anne's womb without any contraceptive precautions.
