Bedding my Schoolteacher

I left school at 16 and became mechanic and 8 years later I met my old schoolteacher. She didn't remember me, which isn't surprising as I barely attended any class. I was obsessed with cars and my parents finally let me leave to become a mechanic. I bought an old house at 20 with help from my parents and grandparents. It wasn't much to look at, but it had a large steel shed on its large block. Which was the main reason I wanted it. With family help the house was improved and made livable according to my mother. I wasn't concerned over the house; I was just interested in the steel shed. But the house was a lot better than it had been before. I fitted out the shed to allow me to work on cars on the weekend, either for personal projects or to make some extra cash. With hoist installed and air compressor and other things, it was almost as good as being at the garage I was employed at. I did date but wasn't in any relationship at the time I met my old teacher 34, separated and divorcing at the time. Due to the legal costs and rent along with teacher's being lowly pay. She was struggling to make ends meet at the time of our meeting. She was told of me repairing cars at lower cost than proper garages. Her car was needed to get to her school job and home again. No public transport serviced her actual requirements, and it meant waiting over an hour just to get within walking distance of her rented room. So, with car playing up, she decided to have check it over, hence us meeting again. She came on the Saturday morning and I could hear her car running rough, I always give a free quote first. No other paying work at the time, only a private project. Serval things found in the inspection; most minor problems easy to fix. Tune up, oil and grease new spark plugs filter etc. But there were 3 bad oil leaks, and all 5 tires replacement required. As she was my old teacher, I done tune up, oil and grease and new plugs and filter for parts cost only. The next weekend I would fix the oil leak by stripping down the engine changing gaskets involved and change the tires for her. She didn't a spare, but I'd a spare rim and would retreads for her replacements. The following Saturday she was back to get everything else fixed. She stayed like the previous Saturday while did the work, again I only charge for parts (tires & gaskets). She paid me half straight away and would pay the rest in a week or so. I also gave her my number in case she ever had car trouble. She paid as promised and a week later, she rang me her car wouldn't start, and I went to see what was wrong. Her battery had failed completely, and another was required. I'd another battery at home in my project car, that was a match. I got her car start and she drove it to my place. I followed and changed the batteries over and was already dark by then and had started to rain heavily. That when I found out her windscreen wipers didn't work. New wiper motors required, I could've drove her home and replaced the motors next day Saturday, But I offered her my spare bedroom instead and her accepted. We had dinner together and one thing led to another, and we slept together. Having Sex again in the morning and her staying overnight again only going to her home late Sunday afternoon. The following weekend she came by again nothing wrong with car, she had been thinking and thought as we got on so well. Maybe she could rent a room off me instead of her current place and be closer to her school. Sex wasn't mentioned but was the main reason I said yes. But I didn't say so, we do have sex from time to time. Not in any relationship with each other than friendship.
