All In The Family

When I was 13 my oldest sister, then a full figured 19 year old, came home very much under the influence. She could hardly speak let alone walk. I got it because our parents were away for the weekend, she and my brother (21) like to turn on the bad, with when the cats away, behaviours. I tried to help her to her room but her being at the time, bigger than I, it was impossible. As I attempted to get her up on her feet I could see with her mini skirt, that she wasn’t wearing panties. I gave up on moving her lifeless body and let her lay there on the floor. I stared at her exposed hairy pussy. I couldn’t help but spread her legs giving me a much greater access to her vulva, my very first exposure to a real life one! I gave it an intense inspection, moving her her lips and pee-flaps open. I went as far as lifting her legs up sniffing her, getting a full shot of her anus and slit putting my fingers in her. I took note of a white substance oozing from her twat. It was obvious that she had been freshly fucked. I of course had a rock hard erection through all this. I knew what I was wanting to do was wrong but my urge was stronger. I took off my pants and entered her pussy with my dick. I could not believe how fucking great it felt coming in but one minute of being in her. She just laid there every now and then moaning. I undid her top exposing her incredible breasts. I felt them, suckled on them, they were great. She moaned, looked at me and smiled saying, “You little fuck! Stick your cock in me!” I did again, lasting maybe 3 minutes before cumming. She said, “Help me up you little shit.” I did, helping her to my room since it was a lot closer than hers. I gave her several glasses of water to help her sober up. After about an hour, she told me to take off her clothes, now with her laying naked on my bed. She told me to get naked as well. “Nice cock for such a little guy” she said. She placed my cock in her mouth, sucking me to orgasm. I thought she was chocking on my cum, which she was, followed by her puking all over my bedding. It was a hell of a mess. Her entire night of whatever, blowing out her mouth. She got up, showered and went to her own room. I thought it was a one off night but sis would often come home intoxicated and not, crawling into my bed and fucking me hard. Many years have gone by now, she’s been married and divorced twice and I once. Last week she came for a visit. After a few we reminisced about our sex life decades ago into her mid twenties.
We thought, what the fuck and did it again.
Talk about loving the one you’re with.
