I seduced my mother without trying

My mother Joyce 46 and my father Harrison 49 were fighting a great deal and Harrison was going away on business regularly. I'm the youngest of 2, my sister is usually away at university and that leave me Jonas 21 home with Joyce alone the most. I didn't go to university I left school after finishing high school and wasn't interested in years more learning. I train as a plumber as I knew from a friend that plumbers made good money. Anyway I was at the golf club when Harrison left early to catch a plane interstate, it was a party for a friend of theirs birthday. Joyce had wanted Harrison to catch an early flight the next morning, but he decided to take 5pm flight and have night in bed before his meeting. Joyce drank more and more and I decided I should take her home before she either passed out or fell over. It was easier than I thought to get her to go home early with me. On getting home she started drinking again, I told her she should shower and have a early night. She said she had planned to have an early night but HE wouldn't take a later flight. Anyway she was having trouble standing and I helped her to her bathroom and she just on the toilet seat. I had to help her undress and then I undressed and showered with her. While I washed her I copped a feel as they say and she didn't say anything and I kept feeling her up. I also got a hard-on myself and with asking inserted into her and pumped her until I came inside her. Still not telling me to stop and while drying I decided to take her to bed and fuck her again. I slept with her that night. In the morning I awoke to her sucking my cock, she wasn't annoyed or upset that I had used her the night before. She told me that Harrison didn't want to fuck her. I could anytime I wanted and since then I've been her go to guy for sex. Harrison either doesn't like sex or to engrossed in his work to care, either way I'm getting regular sex from Joyce and have become a total sex addict.
