Riding Mom

I'm Adam 24 single live at home my parents Patrick 46 and Amanda 43 and my sister Carol who is at university. Patrick is a keen golfer and fisherman and is away most weekends fishing or playing golf or both. Carol is away at university mostly or rarely at home when she is on breaks from university. So most weekends I'm home with Amanda and I started seeing her as a sexy woman and not as my mother. Last December Patrick went away on golfing and fishing trip with some his buddies and Carol went skiing with some of her friends. This left me and Amanda alone together, Amanda likes to have a G & T in the evenings after dinner. Anyway I got a bottle of Vodka, not the local stuff the real burn the air off your chest stuff and I got a bottle of it and as it was tasteless I replaced half of Amanda's Gin with it and add some to her bottle of tonic as well. I waited to see if she would notice and after we had dinner that evening and clean up. She sat down with her G & T to watch T V, I wondered if she would notice anything different. But we had chilli for dinner and I think the chilli taste was still in her mouth and she drank her drink without any problem. But she seemed to drink it faster than usual or did the high alcohol evaporate away I wasn't sure. But unlike other evening she made another drink and drank it as well. After a while she was tried to get up and was having trouble standing and I helped her stand. I was also feeling her up as I was holding on to her, I took her to bedroom and sat on her bed and left her sitting there. I went to pee and shortly after she called back saying she also want to go to the toilet. I was only in my boxers at this time I helped her to toilet and after she had lowered her panties and sat on the toilet I was standing in front her and I had a hard-on. She noticed I a bulge in my shorts and gave me a feel and my cock poked out the fly straight at her face. She quickly took hold of it and started playing with it. She was stroking it and it started to burn from the friction of stroking my cock. I told I needed to get a wet cloth for her to keep stroking it. But instead she started to suck it. Just to wet it at first and then she sucked me right off I blew my load in her mouth and she swallowed it. After I took her back to her bed and helped her into it. Thinking she was ready to go to sleep, but she said I done you now you do me. She undressed completely and I done what she wanted and by the I had finished her I was hard again and just mounted her without asking her first. I blew my load inside and slept the whole night with her. Next day we were still together bed together both naked and I awoke first and was thinking about showering when Amanda awoke and told me to fuck her again. Which I did and then we showered together and after breakfast Amanda wanted more sex and we spent most of the day fucking. Since then anytime we're alone together she wants sex. She told me Patrick isn't doing her much at all and as I'm willing she is making the most of it.
