Helping my mother

I'm 26 a carpenter by trade and lived near my parents and then they divorced. It wasn't unexpected, I had mainly moved out to get away from their regular arguments. I had a room at a hostel, and it was just big enough for a bed and not much more. My father departed to live in the next state and my mother 53 got the house. But no alimony, so she had to work to support herself. I stayed at the hostel to allow thing to cool as they say. Then my mother had a fall at her job and was left with unable to walk for a week without assistance. Taking the chance, I moved back home to assist her. As the younger of 2 and the closest to her. My brother is married, and I decided it was me who should assist. She didn't need much help just mainly getting to appointments and in and out of the car. Once she recovered, she wanted me to stay with her. The family home is a 3-bedroom 1 bathroom Ranch style and one day after work I was showering and started to masturbate myself. My mother came in saw what I was doing thru the clear glass and joined me in the shower. She took over stroking my cock and I played with her body, we had sex in the shower and then in her bed. That is how we are now; I fuck her regularly and sleep with her every night. I haven't a girlfriend not that interested in finding one either as my mother gives me everything want at the moment. She is well past having children and so no worries with precautions either.
