Mom Needs It.

About two years ago I was surprised to learn that my mom is something of a nymphomaniac. It is a trait which she has managed to keep fairly well hidden.
I was over visiting my parents and we were all talking, and somehow during the conversation my mom mentioned how she wouldn’t mind having my dad and I share her sometime, that she would find that exciting.
My dad looked a little self-conscious, apparently aware of her sexual appetite. He just sort of said how that would be fine with him. I wasn’t sure and asked her if she mean like both of us at the same time. She happily said, sure. My dad just shrugged and asked me if I wanted to. I kind of didn’t know what to say, and said, sure. My mom went off into the bedroom and when my dad and I came in a minute or two later, there was my mom naked on the bed waiting for us.
We got our clothes off and my mom invited me to join her. So I did. I was a bit nervous and intimidated being like that with my mom, and to have my dad right there watching. But he seemed to have no problem with it, and my mom and I proceeded to have sex while my dad watched approvingly. Then when I finished dad took his turn with her and I watched.
It was quite a surprise to see my mom being so sexual like that, and It was something of a turn on. By the time finished I was ready to go again and so my mom and I followed throught.
Now for the past two years I have been joining them for these regular and really great and fun sex sessions. On more than one occasion my mom has performed oral sex on me in front of my dad, and has done the same to him, and my dad and I have even had anal sex with my mom, as she likes this and finds it thrilling. At first I wasn’t too sure about doing this with them, but now I can see that my mom thoroughly enjoys our threesomes and likes to have sex multiple times and that she needs this to be satisfied. All I can say is that I’m glad that I can help out.
