My Maiden Aunt

My aunt 52 is the oldest of 3 and only girl in my father's family and she put her career before having a family. I'm the oldest of 4 in our family 2 boys 2 girls and left after high school as I wasn't doing well. Trained as plumber and now qualified, was asked by my aunt to update her plumbing. I 24 agreed and would do the work on weekends, I'm moderately successful dating and do get laid. But no actual girlfriend just girls I know who put out. My aunt is slim and looks great all the time as she is always well dressed, and my father says she never been kissed. But she is a driven woman, anything she wants she goes for it and never gives up till she gets it. I arrived early 6am to start work and she was already up and looked great as usual. I started putting in the new pipes and when everything was in place, I connected the new and once done removed the old pipes. It was just after 6pm and I was filthy from being under her home and I'd other clothes and would shower before leaving. I removed my coveralls and was showering in her spare bathroom, and she entered and joined me in the shower. I was shocked at first but rose to the occasion and I fucked her in the shower and after we had dinner together and I stayed the night with her. Fucked her all Sunday and finally got back to my place at 8pm and had promised to visit her the next weekend. But she decided to visit me on Wednesday evening bringing dinner with her, having rang me first. My aunt loves sex I found out and really drains my balls. I still date girls still but have become my aunt's living dildo.
