Shaving my mother's pussy

Long story short, my father was very ill for years and passed away in March 2021. My mother Elaine 44 is quite good looking and use to staying home with my late father. Never a party girl and is well off due to family businesses and not needing to work. I'm John junior 25 named after my late father and his father before him. I'm the eldest of 3, my two sisters are at university most of the time and only come home on their breaks. I was never good at school and became a mechanic as I love cars and lived at home and still do. Since the death of my father, Elaine has kept to herself mostly and done garden and rarely go out. Mainly shopping on Saturday mornings with me or to a movie also with me. I do date and have had some success, but no girlfriend at the moment. Anyway Elaine was reading a women's magazine and it mentioned that women shaved their body hair under their arms and around their pussies. She always done under her arms, but hadn't ever done her pussy. I was the only one of her children home at the time, curious about what she had read she asked me did the girls I date shave their pubic hair. Yes I replied, I don't keep secrets from my mother and as I stayed out all night at times with my dates. She would've guessed anyway, then to my surprise she asked why, it either wasn't mention in the magazine of she was just checking. I said it was a matter of personal taste or they believe it allowed them sexual pleasure. That seemed to satisfy her at the time, after our shopping trip the next morning. I was helping her put away the shopping and she straight asked me to help shave her pussy. I was a little shock at first, but I said I think the girls go and get waxed. No fear she said I shave my legs as I had them waxed and it was pure torture. Okay I said I'll help you shave, after we went to bedroom and removed her panties and she had a big bush of pubic hair. I decided to cut it back as far as I could with scissors first, once that was done I shaved her pussy with a razor. I told her she had a cute pussy and rub some lotion over the area I had shaved. She enjoyed me rubbing in the lotion and I went a little further and than further still. Till I was actually fingering her and I than went down on her and than mounted her and fucked her. After as we laid together she told me thankyou I needed that. If that approval the flood gates opened, I would start to feel her up and even join her in her bed and sex became regular between us. I still dated and got luckily now and then and on getting home I would also try it on with her. Not always successful, but enough to keep me trying. My older sister Catherine 23 is engaged and always going out when she's home from university, my other sister Gwen is more like Elaine quiet and rarely goes out at all. Last time Gwen was home Elaine was visiting her old aunt Ruth for the day wasn't very well. Catherine was out with her intended Gordon and I was alone with Gwen, I heard a soft moaning coming from Gwen room. Realizing Gwen was masturbating herself I walked in and caught her in the act. While she was still shocked at getting caught, I joined her on her bed and took her virginity. She was a great fuck and I done twice that day. On Elaine getting home, I kissed her passionately in front Gwen. Then followed by kissing Gwen passionately in front of Elaine, then taking their arms took them to Elaine's bed and we had a threesome together. Both Elaine and Gwen are my willing lovers and also enjoy each other without me. I take precautions with Gwen, but I wouldn't be too concerned if I got her pregnant. I date more when Gwen is back at university and have travelled down to visit her on weekends with Elaine and we fuck together in the hotel room every time. Catherine isn't aware of our lovemaking, but I wouldn't reuse her if she wants to join us. But she is totally involved with Gordon and unless that changes, things will stay as is.
