My Mom's plaything

Joseph 24 going to local university and doing quite well in my studies, I don't do well with girls and haven't yet had a date. My parents Richard 67 and Barbara 47 are of the social elite. I have a sister Helen 26 who is engaged and lives with Gordon 28 and they are to marry in June. Last October there was a little trouble in the family, no arguments just a tension you could cut with knife. Richard was either working or playing golf and Barbara wasn't happy. Then Richard when away straight after Helen's birthday and engagement party and that annoyed Barbara. The party was held during the day so he could go away for golf. Those all smiles I could sense she wasn't happy and also she was drinking heavily. As everyone left so did Richard, leaving me and Barbara which was usual for a weekend. Barbara continued to drink, I went to my room to study and be out of sight. But as it turned out, I wasn't out of mind. A while later Barbara came to my room drunk and totally naked and told me if I was a good son I would have sex with her as my father couldn't get it up anymore and couldn't take the blue pill due to high blood pressure. To say I was shocked is understated but it will do, Barbara is a good looking woman for her age and has a nice body. I usually masturbate to pictures of naked younger women on my computer, but now I had a real woman wanting me to fuck her. I was slow and that annoyed her a bit, but we had sex and then she sucked me off until I was hard again and she mounted me and rode me until I came inside her. She fell asleep in my bed and I awoke first in the morning and decided to shower. Unsure of how she would act when she sobered up, while showering she awoke in my bed and then joined me in my shower. She remembered everything and didn't care that I had fucked her, other than wanting to be fucked again. Which we did in and after the shower, she really likes sex and I was now her sex toy. She told me straight out that Richard didn't want to do her, so it was up to me to satisfy her. I had enjoyed the sex, not the first as much as the others that came after it. On the Monday evening, Richard was home again and went to his office like he usually did. I went to room to study after dinner as usual for me. Shortly after Barbara came in and wanted fucking and we fucked on my bed. Then she left and I done my studying, that how it was every night that week. On the weekend Richard went away to play golf and Barbara drained my balls. Richard would go and play golf or would go away for business and Barbara slept with me. In January Barbara had an accident and couldn't walk as she had twisted her ankle. Richard still went to play golf and Barbara had me service her in her bed. That's how it is now Barbara still loves to fuck, not everyday like when we first started, but I get drain every weekend. Whether Richard home or not, I still haven't a girlfriend. But am able to talk to the girls better now and maybe soon get a girlfriend.
