My Aunt Katherine

My aunt Katherine 39 single my mother Joanna 44 divorced only sibling dropped by to visit me while in the town I lived. I'm Andrew 27 single and work for a bank, I have my own house and wasn't in any relationship. Katherine hadn't ever married and had been busy with her career and due to her company being taken over by a larger company. Was now out of work and had decide on a holiday/break before looking for another job. With no real plan for what she was going to see or do on her holiday. I asked her to stay at least until after the next weekend, she agreed and would stay at my place. On the Friday after work I asked her to go to dinner and a movie and she accepted. The movie was a bit to sexy for seeing with your aunt, I thought while watching it with her. But she didn't say anything and after we had a couple of drinks and talked. Then heading home, Katherine then straight out asked to sleep with me as she was horny and she had always been straight to the point type of a person. It wasn't a concern to her that I was her nephew, I was a man and she wanted fucking. I agreed and we spend the night together and most of the months later I got a call from Katherine and she would I mind her returning for another visit. I told her your most welcome to come anytime, 2 days later she turned up. She had another job and could work via computer anywhere with internet connections, I noticed straight away she was pregnant. I soon learnt I was the father and that the baby was healthy. She wasn't concerned about being pregnant to her nephew, just wanted to be near someone when the baby arrived. I was delighted and shocked in equal measure, she slept with me from the start of her return and we started to fuck. Joanna came 3 days later already knowing that Katherine was pregnant and also knowing of her previous visit to me had put 2 and 2 together and guessed I was the father. She wasn't angry or upset at either of us and didn't try to stop us sleeping together. Katherine and Joanne had a long talk while I was at work and I found out on getting home that evening. I was told that Katherine would stay with me after the baby came and Joanna would also move in with us and asked if I had any objection with that. I hadn't any objections and was quite happy with it all. I suggested we all go out the next night (Friday) and celebrate and Katherine said great idea. After the dinner we all got home and Katherine said lets celebrate in the bedroom and to my great surprise Joanna agreed. I fucked Katherine and then Joanna twice, the following Monday returned home to start getting everything ready for her move to live with us. A month later she was living fulltime with us and had another job with the same company, but now in my area. In March our baby daughter Elizabeth after their late mother was born. I still regularly fuck both and sometimes both together. Katherine is thinking of another child before it's too late for her and I have agreed to father the baby again. But I'm looking for a girlfriend, as both Joanna and Katherine have told me find one. I will still be able to get a fuck anytime from them even after I get a girlfriend I want a fuck. I told them I'll always want to fuck them.
