My mature work colleague

I'm now 32 and this time last year, my work colleague Carol 55 as having a hard time financially. Last her husband (heart attack) in June 2023, with his funeral and medical bills along with just one income she needed a cheaper place to rent. Neither of us are anything special nor were we dating anybody either. I've 4bed 2bath house, I'm paying off and as I live by myself another colleague suggested to Carol, she ask me about renting a room off me. Saying it would also save her money on getting the bus to and from work. With nothing to lose she asked me, not really interested but I liked Carol so agreed. Decided not to charge her rent as she did the cooking and my washing her suggestion. Pleased with how everything was going we settled in living together, the cleaning of the house was a mutual effort. Not that I'm a messy guy, usually just dusting and vacuuming. Over a couple of months, we had settled into a routine. Finally getting home from work on a Friday night together, I thought I would go and see a movie and have dinner out as well. So, I asked Carol about joining me and she agreed, meal at a diner saw a movie and had a few drinks at a bar. Got home Carol gave me a hug as a thank you, I got aroused and she saw it. Deciding to get me off she suggested we sleep together; we had sex twice; it has been a case of once you start you can't stop. We regularly fuck now, either I ask her if she is willing, or she asks me. Still not dating anyone, our sexual relationship is for our mutual benefit. I'm very happy I agreed to her living with me.
