My Shy Cousin

I'd recently divorced after 23 years of marriage and returned to the town I was born in. I could work from so it was no problem workwise relocating. My parents were both deceased and only sibling 64 was on the other coast with his family. Back in my hometown there was just my aunt 78 and her daughter 60. I was 61 at the time and my aunt wasn't doing well health wise. My cousin had been homeschooled and is ultra shy around most people, but when she gets to know you, she isn't so shy. But not outgoing as most people usually are, I bought the old family home, and it is across the street from my aunt's home. So, I was a regular visitor to my aunt's home and my cousin relaxed around me. So, when my aunt illness worsened, and she was in hospital. I was the one to watch over my cousin and take her to visit her mother. My aunt told my cousin to do whatever I asked her to do, and I would look after her. My aunt died after a suffering a heart attack and it was just me and my cousin, having my cousin live with me seemed the best option and her now house was sold. She settled in fairly quickly and kept very close to me, everywhere I went I took her with me. We were home and a storm was brewing, and the wind was blowing. So, I decided to shower just in case the power went off and told my cousin I was going to shower, normally she would watch TV. But this time she followed me, and I quickly remembered she didn't like storms. As we were getting very well, I decided to shock her and said if you want you can wash my back. Not expecting her to agree, she didn't say anything, and I entered the bathroom and she followed. I started to undress and said if you're going wash my back you'll need to undress also. Fully expecting her to leave the bathroom. She undressed instead, so I got into the shower, and she joined me I washed her, and she washed me. Nothing other than that, the next time I was going to shower and there weren't any storms around, I said I'm going to shower and asked her to wash my back again, just to see what she would do. She said OKAY and got up and again joined me in the shower. I gave her a feel up while washing her and she didn't react in anyway. After as we dressed for bed, I asked her to join me in my bed and she did without any hesitation. I didn't try anything and so she started sleeping with me every night since. I had to go to the city and as was now usual brought her along with me. Sharing the same room and bed and on our return, we were going along as was now usual. Except one evening when we were showering, I got a hard-on and as she was letting me feel her up, I mounted her in shower fucking her for the first. No attempt to stop me and later I fucked her again in our bed. Now she was my lover and I'm regularly fucking since. Everyone thinks she is my wife anyway and we're too old to have children and she is happy with our relationship. But I'd to ask her why she did everything I asked of her, and she replied Mommy told me to do whatever you wanted me to do. So, I asked then do you like me fucking you and I was very happy to hear her reply yes very much.
