Mom takes sleeping pills

My mother Fiona 47 divorced couldn't sleep so she got her doctor to give her sleeping pills but they weren't strong enough. So she got stronger ones and was out like a light after taking them. You could have a war outside of her room and she wouldn't hear it or would it wake her. Especially after they had first taken affect on her, after a hours they would wear off and she would wake up. I'm Franklin 24 her only child and I live with her, not much good with dating girls and so I hired hookers to get sex. I'm average in looks like Fiona and neither of us date that often and while sitting at home bored out of my mind. I realized Fiona was dead to the world in her bedroom next door the lounge where I was. She had gone to bed after taking her sleeping pill and I decided to see how good they had worked. I went into her room and she was out to it, I started feeling her breasts and moved lower and fingered her. No reaction from her and so I went further and removed her panties and licked her pussy. After I mounted and fucked her, before cleaning her up and putting her panties back on. I started doing that every chance I got, like her I worked shifts and sometimes I was working when she was sleeping. A month or so later we both took holidays to have a break and it away for a few days. We stayed at the same place in the same room, Fiona didn't take any sleeping pills. So I didn't try anything, after a few days I had been out and returned to our room catching Fiona masturbating herself. She was shocked at getting caught and I got an instant hard-on. On seeing my hard-on she became curious about my hard cock and asked to see it. So I showed her and she started to stroke it and I started to feel her up. Then I just kissed her an pushed her back onto the bed and got on top of her. This led to me fucking her while she was awake for the first time. After we had finished, the genie was out of the bottle and sex now became regular thing between us. On returning home I moved into her room with her and fuck her every chance I get. She has stopped taking the sleeping pills and sleeps better now than before our sexual relationship. We both enjoy the sex, but Fiona says she wants grandchildren. But I don't have a girlfriend as yet and grandchildren will have to wait awhile yet.
