I went to help my Aunt

Last weekend I was the only one home as everyone else were away and the phone rang. It was my father's sister Elizabeth 43 and a bit of a drunk, she had run off the road and needed help to get her car out of a ditch. Her husband was away also and she had 2 daughters who at their friend's places. So she rang us, as my father was away it was up to me to Elizabeth's car out of the ditch. I own a pickup and grabbing a snatch strap headed off to help Elizabeth. I'm Andy 22 and work in landscaping and as soon as I arrived I knew she had been drinking. Luckily the car wasn't damaged just didn't have the power to get back on the road. I hooked up the strap and towed it back on the road, then checking to see if it was okay to drive. It was the drive had been in the air and so it could get out of the ditch. We were a lot closer to my home than Elizabeth's home and I told her she should follow me home and I would check the car over better there. She agreed and led the way and I followed her back to my place. I let her inside the house and gave the car a better look over just in case I had missed something. It looked fine and I went inside and Elizabeth was laying on the sofa. I told her car was okay and she said she would make it up to me. I said that's okay all in the family service, she got up and I thought she shouldn't drive until sobered up a bit and told to use my parents bed for a nap. She looked at me saying you think I'm drunk, just a little I answered. I'll show you I'm not drunk and she completely undressed in front of me. I was totally shocked and also got an instant hard-on, Elizabeth is a horny looking woman even if almost twice my age. I asked why are you undressing and she replied it better to fuck naked than dressed. Then she asked why I wasn't undressing, I said your my aunt and it's incest. We're not making babies just fucking, don't be such a prude she answered. With a hard-on I couldn't say I wasn't interested and I went with her to the bed and we had sex and she really drained my balls twice and later after she left. I missed her almost straight away, next morning Sunday she drove up to the house and came inside and asked how I was. I said Okay and thanked her for the sex, she than said I still horny you up for a repeat and I nodded and we again fucked several times that day. I've had girls friends off and on and have gotten a fair amount sex, but never had as much sex on a weekend before as I had with Elizabeth. My family got home yesterday and I saw them on my finishing work. Shortly after Elizabeth turned up and she asked me straight in front of my parents to go to their house in the country and help her clean up the garden and yard. Winking at me at the same time, I was about to answer, when father said he'll be happy to help you. I don't much gardening or clean up is going to get done and I'm excited about going with her.
