My Sister

Many years ago, I was 15 and my sister was 14, one night about 3am, I was suddenly woken as I realised that I was not alone in my bed and suddenly I heard my sister whisper that she was naked and she began pulling my shorts i was wearing down, I was shocked at first and tried to get her to stop, she gave a little giggle and pulled my shorts off and she positioned herself in the 69 position over me and she asked me to lick her as she began sucking my penis, I should have made her stop but it felt so good and I began licking my sister, it was fantastic we 69ed together and finally had sex together, she has asked for sex together number of times in past 40yrs and ive always refused but I regret not fucking her again.
