First Apartment & Money Shortage

So a few months ago I finally finished my studies to become a psychiatric nurse. I saved up a bit of money and finally (it wasn't bad at my moms house it was just time to move out and be on my own) moved into my first apartment. It's nothing special but I like it. To save some money I buy a lot of furniture and other stuff from a kind of swiss craigslist. A week ago I visited a other user to pick up a nice bookcase for 60 bucks. I arrived at the doorstep and rung the bell. A short time after a really attractive lady in her 60s opend the door. She wasn't wearing a mask and asked me if I was there for the bookcase to which I agreed. She told me to come in and offered me a coffee. I was pleased to see some hospitality in these strange times and I couldn't say no. I asked for tea instead and we ended up talking for about 15 minutes. It was my only offday in that 6 day work week and I steered the conversation towards the price of the bookcase. She now knew that I was working as a nurse and short on money. She told me that 50 was more than enough. I thanked her for the reduction in price and she quickly strung me up in a conversation again. I don't remember much but sometime during that conversation she mentioned that there was a second option instead of paying. I dug deeper into this second option and she vaguely said something among the lines of "helping her instead of paying". After some more talking I asked her what she was hinting about. Strung into a few sentences she basicely asked me to fuck her and get the bookcase for free. I think that she is about 40 years older than me but I actually have a lot of fantasies about older women and I could even save money at the same time. I agreed and a short time after she stuck her tongue down my throat. What followed was a good 30 minutes of very amazing sex. She even convinced me not to wear a rubber which ended in me clenching and cumming inside of her pussy for what felt like 10 seconds. She had multiple orgasms while I licked her beautiful hairy pussy and came once while rubbing her clit while I was slamming my dick inside of her as deep as possible. After I came she told me to leave my dick inside of her until it wasn't hard anymore. So I was kinda laying on her and we talked for a bit in that position. Fast forward 30 minutes and a second round later she told me to visit her again some other time and hinted that my wallet will be happy as well. So for the past few weeks I visited Margret who I know now is 63 on a weekly basis. We have what I consider amazing sex everytime and most of the times she prepeares a meal for me in advance which was always super delicious. I leave with 50 to 100 bucks everytime and I'm really happy with this situation. I can experience some of my fantasies, get money and even dodge the whole relationship drama I despise so much. So at first I kinda did it for the money but now I would do it even if there wasn't any money involved anymore.
